problem connecting to the house internet

Hi this is my first time on a site and I just wonder if anybody can solve my problem!
I,ve read a few posts and set my xda llI so that in connections my network card connects to work!Also have done all the rest and set it to internet just in case as well
My Isp in connections window is on the advanced tab and select networks on the network Management is set to My Isp.
my Wirles Lan Manager is status connected to network
My ssid is the one that all the house computors are set to,my mode is Infratructure and Tx is Auto.My channel is 6
my bssid is 00-18-2D etc etc.
My Mac is 00-09- etc ,etc.
My IP.169.254.168.73
signal quality is good
I,ve been onto the 192.168.0.1 website and added the mac address of the xda lli but when I try to get the internet on the xdalli to connect it justs says default page. I cannot seem to connect. is this normal or do I have to go through O2 to pay for another internet connection besides my home address one.Have I missed something out!Help would be greatly appreciated! thanks

Hi,
Your IP of 169.x.x.x means that you are trying to use DHCP to get an ip address but haven't been supplied one by your router..
The ip addres of your router is 192.168.0.1, so it may be sensible to setup your router to allow a dynamic address range of 192.168.0.100 to 192.168.0.110 (say) - when anyone tries to connect using a dynamic address (using dhcp), they'll be given an address in this range.
So, initially check if DHCP is enabled.
Do you have a laptop that connects using a dynamic ip address (ie not static - ie not implicitly defined) - if so then DHCP _is_ already working and there's another problem.
If this is the case, I'd initially disable any kind of mac-filtering or security until you get a simple connection going..
Sorry, if this isn't too clear - I'm tired - what router are you using?
Kev

First hand it can depend on your router
I have had problems connecting with Virgin broadband routers for instance.
Have you tried connecting elsewhere?
Also what type of security do you have on your router?
One more thing to try
Check under the "Network Cards" settings when disconnected and select "the internet" from the drop down menu.
Hope this helps

clearing the way so that I understand correctly!

My router is a netgear dg834GT.I,ve looked at the range and the range for 192.168.0.1 actually goes from 192.168.0.2 upto 192.168.0.254 so the range should be there. how would I know if the router is DHCP, is there a way of seeing this? The filter would be set up where for the mac address?Is there a way of changing the isp on the phone so that its range is within the 192.168.0.1 range?the only security that I have is the routers own and the avg antivirus.would disabling the avg help!

thanks for your response!

If you haven't set up mac filtering, then it won't be a problem.. if you have, then there should be an option to disable/remove any you've input - build security up from a working setup.
Have you (can you borrow) a laptop that you can setup wireless with a dynamic ip address and check that connects; if that's okay then the router is setup correctly.
So I the Alpine comes up with "connected to network" but the ip address is 169.x.x.x ..
This means that the Alpine has not been allocated a usable ip-address by the router for some reason and you'll get nowhere until this happens.
Your other PCs.. are they set to dynamic ip addresses - I guess so as you have no room for static addresses. You should probably check they're all dynamic as if (say) you've allocated a static ip address of 192.168.0.2 to one of them and then DHCP tries auto-allocating addresses, I guess there could be a conflict (don't know how clever dhcp is). Usually I would set the DHCP range to 192.168.0.100 -> 192.168.0.200 (allowing 100 different dynamic addresses).
Have you checked that authentication is set top 'Open' and Data Encryption 'Disabled' on the Alpine; and ensure you've disabled (temporarily) all router security..?

Thanks kev for replying.
I have a hard wired lead to the router for one computor and 3 laptops connected by wifi and another computor connected by wifi.
the range or should I say the ip addresses are 192.168.0.3,192.168.0.4
upto 192.168.07.I,m at work at the moment but as soon as I get home tonight I'll set the wep key to disabled is there any other thing on the router that I need to do?

Can't think of anything else...
But at least you know DHCP is working if the other PCs are getting ip addresses okay.
And you know the wireless is working...
So it does look likely that it will be something to do with WEP/WPA encryption... (I guess you've got it setup at home), hence why the router isn't allocating you an ip-address.
If you can't get it going, it may be worthwhile doing some sceenshots of the router configuration pages (or config files)...
What I can tell you is that what you are doing looks correct and you have everything setup so you can go on the internet whilst at home using the Alpine. Mine uses the router whilst at home and GPRS whilst out.

The dg834GT is pretty much the one that Virgin use, like I said in my earlier post.
I have found these particular routers to be a problem (sometimes) with my Alpine.
You should try to update the firmware.

Well Done Kev!
It was the "open"on the phone and putting "open" on the router.I had to intiallely disable the wep key.then when I got connected,I reactivated the WEP key and I could not connect.So on the phone I unticked the automatically connect to my name of my router name and reput in my encryption key again and I was in and On line.Thanks to both of you(Kevcal and Voxshots) for helping me.Definately could not have done it without you Pair.I like the idea of using the screenshots so I,ll post a screenshot of all the settings on the phone and computor so that anybody else will be able to resolve there problems with all credits going to you people on the bottom!

Very happy to have helped and glad you sorted it out

setup issue "We weren't able to discover your Chromecast on the network"

I'm trying to connect my chrome cast to my wireless AP. I get the error message "We weren't able to discover your Chromecast on the network"
I've read that AP isolation is the problem, but I'm pretty sure that isn't enabled. And if it is, I have no way of disabling it.
I have a dlink DGL-4500 and a DAP-1360 running in parallel. Same ssid, same password, same channel. It's a seamless transition from one to the other when I walk from one to the other. I can even stream video with no problems.
Chromecast won't connect to my AP. I don't have wlan partition enabled. I don't have igmp snooping enabled.
I do have wmm enabled.

Have you tried turning one of them off to verify? Also are you running on 2.4, 5 ghz or dualband? I'm using cisco/linksys setup with a repeater (regular router on ddwrt) but they all have different ssids(3 total) and I know it works between them except obviously the chromecast won't connect to the 5ghz one.

I only use 2.4GHz. the DGL-4500 is either/or.
I've turned off the wireless on the AP, but the range of the router is too far away to connect.
I tried it directly on the DGL-4500 and it worked the first time. Then half-way through a movie, my phone refused to find the chromecast device again. I had to do a hard reset.

I can find no setting for AP isolation on the DGL-4500. Does anyone else have this router and having it working with an AP?

Make sure WLAN partition is off.
My settings finally were 20MHz single channel, WPA2 PSK, Mixed BGN.
My network is hybrid. I've got the DGL-4500 as the main router. I've got another Linksys WRT120Nish as an AP (which the chromecast is actually connected to at the moment and I've got the DAP-1360 setup in repeater mode in the middle.

Chromecast connected to wifi but cannot access internet

Hi All
Got my chromecast to connect to the router, it even says "ready to cast".
However, on the TV screen it says: Chromecast connected to wifi but cannot access internet.
My router is a TP-LINK N600 Wireless Dual Band Gigabit Router, Model No. TL-WDR3600
Firmware Version: 3.13.31 Build 130320 Rel.55761n
Hardware Version: WDR3600 v1 00000000
For Wifi the settings are:
Wireless 2.4GHz
Wireless Radio: Enable
Name (SSID): Internet5A_2.4GHz
Mode: 11bgn mixed
Channel: Auto (Current channel 1)
Channel Width: Automatic
WDS Status: Disable
I connect to internet using PPPoE
Router is right behind the TV, where the chromecast is.
AP Isolation is disabled
Any kind of help is greatly appreciated!
I have already gone through troubleshooting, restarting router / chormecast, factory defaults for router / chromecast..etc
Called Google, they had me to it all over again, still the same thing.

Well first question...Can you stream Media to it? If your using aVia you shouldn't need internet.
Check Router settings make sure you don't have something like Mac Filtering on (although I would think it would not connect at all if that was the case)
Also check to see if you have Internet Access limited for any Mac Addresses.
Make sure UPnP is enabled on the router.
I looked at the router compat chart and all of the TP-Link routers appear to be compatible so if it is therouter it will be some setting you changed from the default.
Also check to see if there is a firmware upgrade for your router.
I should point out though that Google is notorious for lying about Internet access and in many cases use a successful connect to Google Services as the indicator. If thats the case here then it may very well have Internet access but couldn't connect to Google!
We know Google thinks it is the internet but it isn't the entire internet! LOL
Almost forgot...If your router connect via PPPOE make sure to set it to not expire and stay always on.
If you have it set to connect when needed then the CCast may get a No Net access response while the router is connecting.

Can't stream media to it. Tried it with Avia, (chromecast inapp purchased).
Mac filtering not enabled
UPnP is enabled
There is a firmware update that I will try later today and reply with the results.
Thanks for your support!

If the firmware update doesn't fix things, look for additional options related to Multicast, IPv6 and IGMP

Definitely check your PPPOE Settings to make sure it is always on...
If not then you aren't always connected to the Internet and CCast may only check status on initial connection.
Inability to cast at all says to me that something else in your router config is amiss but It's possible that since it can't get to the Net that it can't retrieve the Whitelist which would prevent casting from anything.

Tried all of the above. Still no joy. Updated firmware to latest, etc..
IGMP Proxy: Disabled
This text is just under the IGMP Proxy setting, in RED:
IGMP(Internet Group Management Protocol) works for IPTV multicast stream.
The device supports both IGMP proxy with enabled/disabled option and IGMP snooping.

Can you successfully ping Google DNS at 8.8.8.8 from another device connected wirelessly to the same router?

Pretty much all the option types that Google mentions for the various routers in their router known issues page, it's worth trying on and off, if your router supports it, and only if you are having trouble. It's more combinations, but worth a shot.
Otherwise, if it ain't broke, don't fix it.

Thank you all for your help!
I disabled parental control (on ISP side), and it worked!
Sorry for all the trouble!

Can't connect Chromecast to Netflix

I took delivery if a Chromecast today and the setup is a breeze. As I'm in Europe I have changed some settings in order to access the American version of Netflix because if the extended selection of films and series. It runs fine on my Galaxy Note 8, iMac, and Xperia Z1. But it can't run on my TV. Every time I try to cast a film on it I get this error: "Whoops, something went wrong...Device Messaging Error. There was an unrecoverable error on your computer. Please reload the page to resume controlling your device."
I have done some searches and found various possible solutions, but none worked. This is what I've tried:
- Signed out of all devices in Netflix.
- Reset the Chromecast.
- Disabled WWM on the router.
I doubt it's an issue with Netflix as it works fine on all devices except on the TV. Sometimes I do see there is an error on my iMac saying that Microsoft Silverlight has crashed but that doesn't seem to affect anything. Is there anything else I could do to troubleshoot?

Please tell us...
What make/model router do you have?
Can you describe how you "changed some settings" to access US Netflix?
Do YouTube and other services work?
If you use your normal DNS settings and access your local Netflix, does it work okay?
Chromecast is its own device and does its own DNS lookups and Internet requests after receiving the "go play this video" request, so if you're redirecting DNS on specific IPs/devices (rather than everything on your network), then you need to be sure the Chromecast IP/device is being redirected.
Otherwise your phone/tablet/computer is in Mens and Chromecast is in the Ladies and...
Phone/tablet/computer: "Excuse me, could you get my phone next to the urinal?"
Chromecast: "What's a urinal??"

The router is a Cisco EPC3925.
I used the instructions from the Unblock-us website. Changed the DNS settings to 208.122.23.23 and 208.122.23.22 as instructed. But I also changed the DNS settings to that on the Cisco router - otherwise the US material would not show on my tablet and phone (only on the iMac).
YouTube and Plex work just fine when casting material to the TV.

Thanks for the info.
Seems like your core problem is that by default Chromecast uses the Google DNS servers regardless of what DHCP provides, so even though you've set your router so all its DHCP clients are being told to use the Unblock-us DNS, Chromecast still isn't. So all your devices are in the Mens, with the exception of Chromecast, which still goes to the Ladies, even though you tell it go to the Mens, thus it responds with "What's a urinal??" when you reference things in the Mens (US stuff).
Chromecast will fall back to using the DHCP-supplied DNS server(s) only if it doesn't get a response from Google's DNS.
Normally the ways around this would be to:
Route Google DNS requests to a bogus/non-existent gateway
Block Google DNS requests entirely
so Chromecast does not get a response from Google's DNS. Which one works depends on how your router handles the blocking/forwarding. You want a timeout or destination unreachable, rather than an outright refusal.
But... I looked in the manual for your router (seems to be a VoIP+modem+router combo) and unfortunately I couldn't find any way to add a static route, nor did I find a way to block or forward requests specifically for Google DNS.
So unless the ability to add static routes or the ability to block port requests for specific WAN destinations has been added, you may be a bit stuck. Definitely check through your router's config to see though, often times the manual lags far behind the current feature set.
However, if you don't have the necessary options in your router, that leaves you with these possibilities:
Add a router that can provide blocking or redirection via one of
static routes
IP-specific port-blocking
iptables rules
to provide network to Chromecast and devices controlling Chromecast (they need to be on the same subnet).
VPN - which is beyond my area of expertise for this usage.
Get a rooted Chromecast so you can use Eureka-ROM to enable use of DHCP-supplied DNS rather than Google DNS
If you go with option (a), you will have double-NAT, which can be problematic.
You would connect the new (filtering) router's WAN side to your existing router's LAN site. You cannot connect the two routers LAN-LAN as the new router will only filter/redirect traffic when it does the IP translation from LAN to WAN.
If your existing router has a Bridge option for its LAN connection, that would avoid double-NAT (bridge will connect the WAN side to LAN side transparently and disable all router NAT and filtering), but it's more likely that you would get a Static Route option before you get a bridge option.
Anyway, contemplate a bit, first check if there's Static Routes in your router's config. Sorry this has been such a verbose post.

Many thanks for your detailed reply!!
I don't know much about modems/routers so would be a bit wary of setting up a new router. I checked in the setting on the modem/router provided by my ISP and there is an option to add static ip. Would that be a way to block Google's DNS?

Unfortunately not - and don't change that - you'll lose Internet connection.
While you're there, though, can tell me what options you have in the Working Mode dropdown where it currently says Router Mode?
DON'T change it though - that's likely to break your Internet connection too.

Cool. If you decide to get another router, you should be able to switch that dropdown to Bridge Only and connect your existing router's LAN port to the new router's WAN/Internet port, and it should avoid double-NAT-ing.
Essentially your existing router would only be used as a modem (and VoIP, if you're using VoIP), and you'd disable old router's WiFi and do all your DHCP, WiFi, etc on your new router.

As a rule I try (best I can) to avoid Dual Purpose networking devices as I have found they do neither task very good....
Unfortunately ISPs are moving towards these all in one boxes (Modem/Router/WiFi) and it Wreaks havoc on those who have their own networking gear....
Whats worse is they are locking the configs of these devices so that you can't change them easily to get it to do what you want.

Sounds too simple to be true. I do have an extra router so perhaps I'll test it out at some stage during the week. Thanks for your help so far!

You can also try this simple test without the router to see if it works....
Connect your computer directly to the Modem/Router...
Set the Router to Bridge Only mode and if your PC gets an outside (Public) IP Address then you know it will work with an external Router.
The only issue you might face is sometimes if the ISP provided the Modem they program it not to accept that change without it coming from their side.

I connected a new router (ASUS RT-N56U) to the existing router/modem. The existing was set to Bridge Mode with DHCP off and it can connect to the internet but not cast any show (local or US) to the TV. Not sure what details are needed for you to help me getting it to work. I can cast local Netflix onto my phone and tablet. YouTube videos can cast to TV.

Not totally up on the settings screens for your new router but check to see what IP Address it has under the Internet settings.
Every Router has two IP Addresses, one local (192.168.x.x) and one Public (should be provided by the Modem in bridge mode),
If both are local IPs then your double NATing which will easily break Netflix. If one is a Public IP then check other settings in the new router most notably UPnP and Multicast.
Also ( sorry dumb question follows) but you did make sure to set up the CCast to connect to the NEW router not the old one?

There are two IP addresses: 192.168.1.2, 192.168.1.254, first one local and the other public. I can't locate UPnP and Multicast in the router.
I made sure to set the Chromecast to the new network. The old one shows but it's not connected to the internet. It's in bridge mode.

As I suspected...Your Double NATing is the problem....Your new Router is not actually breaching the Modem to the Internet.
This modem also has WiFi built in I bet....
The DHCP you shut off probably doesn't apply to anything directly plugged into the Modem. Just the WiFi.
You need to look for a setting that gives you the option of passing a local/internal (192.168.x.x) IP or Outside IP and set it to pass an Outside IP. (this is on the Modem BTW)
If the Router reports any IP that starts off 192.168 for Public then you are not set up correctly.
If you see the option to change from local IP to Outside IP but it is greyed out then your ISP locked it out and they must make the changes on their end.
Call and tell them your Modem is in Bridge mode but doing double NAT translation and you can't breach the Modem with your router.

As @Asphyx said, there's double-NAT going on. This may be a problem, but the core problem at the moment is that new router's WAN and LAN are using the same subnet.
I recommend...
Turn off the WiFi on your old router, if you can.
Look for the stuff Asphyx mentioned.
If you get stuck, call your ISP
Ask them to enable Bridge mode and explain that you're looking for more robust routing and firewall features
Ask if there's a firmware update for your existing modem/router combo to provide this, if there is a different ISP-provided modem/router you can use that has better features, or if they can provide/recommend a modem-only device (if they don't/can't enable Bridge mode)
Ideally, you want to see is your new router getting a WAN address that is not 192.168.x.x
If you reach that point, you're done.
If not, you at least want your new router getting a WAN address that is in a different subnet from its local network.
On your new router, change the Local address to 192.168.2.2
That will switch things on the new router to the 192.168.2.x subnet. Now the new router and old router will be on different subnets.
Make sure any client devices (wired or wireless) that have static IPs set are changed to use IP 192.168.2.something and gateway 192.168.2.2
My network is double-NAT and I have not had issues with Chromecast, streaming, VPN, or anything else, but you definitely should avoid double-NAT whenever possible.

Chromecast Not Connecting to Comcast Modem

I have a Chromecast that will not make a connection to WiFi. You can see it on the network, but when going through the final steps I am told that it cannot communicate with the Chromecast and it times out. Can anyone provide some suggestions?
I am using modem for business class.

You may have tried this already, but did you try power cycling the modem?

Yes, tried everything!

is it possible to turn off AP isolation?

Something that may or may not apply to your situation but should be noted...
Comcast is currently (in some areas) running two Wireless Networks off the router they give you for your home service.
One is for their Public WiFi use (which I believe requires a Comcast login)
and the other for your own local network use.
Is it possible that you are trying to connect to the public SSID and not the local?
Do you see two different SSIDs available?
Otherwise the best suggestion is to call Comcast and let them walk you through it.
I personally never allow my ISP to control my wireless or router and insist they put their equipment into Bridge mode.
If you are having problems just connecting I can't imagine what kind of other issues you are going to face with settings needed for a good CCast experience.

This explains the numerous open xfinitywifi APs I've been seeing lately... Glad I have my own modem.

Yes and also glad I have my own router with it's own security system so that the Modem the public might be connecting to can't possibly make a connection to the local network without a proper router priv.
One of the reasons why I always suggest people do not use the ISP router as their own and insist the ISP put it into Bridge mode so the only way anyone can possibly get a local IP is by going through my routers own security.

I have the xfinitywifi disabled on mine and changed a majority of the default settings.

Anything related to...
AP Isolation (should be off)
Multicast (needs to allow multicast, but the on/off state depends on the exact setting)
IGMP (depends on the exact setting)
?

I'm not having any issues... but I did find this:
I couldnt really find anything regarding AP Isolation, But I know by default ICMP and Multicast are blocked. Theses need unchecked.
Gateway>Firewall>Custom Security
Uncheck 'Block ICMP' and Uncheck 'Block Multicast'
Edit: Setting the firewall to Low Security will also enable ICMP and Multicast
dpalmer76, is your comcast biz router a DPC3939? Its 'Incompatible'...

They let you into the Admin or did you just find your own way in?

Comcast routers have a user accessible admin panel. They have the info for logging in on their site.

I'm actually shocked! LOL

Thank Thad
Here's how I got mine Chromecast to work after getting the "cannot communicate with Chromecast" error on the final step of setup:
Called Thad with Xfinity Customer Service, and he found a fix. Tell your support agent to
Factory reset the modem
Set security of the modem to WPA2AES
Enable UPnP and set the time to 30
Set hops (scale of 1 to 5) to 5
Enable Zero config
After resetting your Chromecast and going through setup, it should begin to work.

So you don't need to even call comcast for this and it'll save you time because they really just don't know.
Go to 10.1.10.1/ on your browser. The User is : Cusadmin and the pass word is: Highspeed. It may change on your region but comcast will give you that info.
On the left menu Click advanced, then under device discovery on the left you will find all the settings you need.
as twill said UPnP enabled. Advertisement period set to 30. Time to live/ hops 5 and zero config enabled
