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.
Enable AP Isolation - Unchecked
IPv6 - disabled
Thinking of giving up on this..

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

Enabled IPv6, but does not show it on router page.
Also, I can ping Google DNS.

Does not show it as in... the router still shows the option as disabled, or something else?
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!

Thanks for your help. For me it was pppoe set to Connect auto, changed to manual 0 - never disconnect works like a charm. (TP-LINK W9960)

Guys i m having same problem and till not resolved.. my smart tv not work chromcast.. but except it working ok like youtubr and other apps, steam too. only chromecast and wireless displays not work.. for last 5 month i m fightin with xiaomi india..

How to setup chormecast in dlink 2750 router

Please help me to set up chormecast in dlink 2750 u router
i can connect to router but it show not connect to internet
thanks in advance

What are the first 4 digits of your serial number? Just curious what firmware build you might be on. If you're on 12072 you might want to get root while you still can!
Looks like your router is D-Link 2750U?
Page 36 lists a Wireless Multicast Forwarding (WMF) option - you might have to enable that for Chromecast discovery to work, but first we need to get Internet...
Page 58 lists a LAN to LAN (Intra LAN) Multicast Enable option - again, you might have to enable that for Chromecast discovery to work, but first we need to get Internet...
Page 63 - Enable IGMP Snooping - you may need to toggle this setting.
Other than those, I dont' really see anything that would specifically block Internet access from Chromecast... Make sure you can ping 8.8.8.8 and 8.8.4.4 from the 2.4 GHz wireless network using another device if you can.

Sorry for the late reply
it work automatically
i just have o brought a wifi extender as my router far away from my tv

Impossible to Setup

I had 2 Chromecast working just fine for a long time,one in the main network and the other in the second network in a room that is too far from the main router.
Then one day i disabled UPNP for security concerns and soon after I realized chromecast needed it and enabled it again, however i was never able to set up it again
I tried using many phones like Galaxy S4, RAZR D3, iPhone 6, Windows 7 PC, I tried resetting the Chromecast to factory defaults many times without success, then I tried the other Chromecast and reset it to factory defaults and could not set up it either, so the problem is on my network.
My wi-fi settings right now:
11n only, it's 2.4GHz only
Channel Width automatic,
Channel is set to 11,
IGMP proxy disabled,
[WPA2-PSK-CCMP][ESS](from wi-fi analyzer app)AES with 54.000 seconds group key update period,
My password length is 13 with ! and () and numbers
WPS disabled
Mac filtering disabled,
Transmit power high,WMM enabled,
Short GI enabled,
AP isolation disabled,
beacon interval is 50,
RTS threshold is 2304,
fragmentation threshold 2346,
using a DHCP server,
UPNP enabled(again),
SPI firewall is enabled ALG all enabled but SIP ALG,
Forbid ping packet from LAN,
Ignore ping from WAN(tried without this too, so i don't think it is this),
Parental control is disabled,
My router uses google dns by default.
I don't use any VPN
My router is a TP-LINK TL-WR941ND my firmware is up to date(3.15.9 for V5 hardware) it is connected to another modem that just run as a bridge and nat disabled if i remember right i don't think it is a problem it with it and the only options related to IGMP on it is IGMP proxy and chromecast support says it need IGMP enabled + IGMP proxy disabled so how i check out this?
I also tried moving the chromecast to a TV that is right next to my router, still get 'can't see the chromecast on your network',
I also tried to give the chromecast a permanent static ip, and port forward it(virtual servers on my router) 2-65535 UDP and 2-65535 TCP but still setup won't complete, i don't know what more i can do other than just trash this stupid chromecast and back to see all my series on laptop.
Sometimes i'm able to cast my tab from a little time after a failed setup but then soon it will say 'no chromecast found', my pc runs comodo firewall however it was not giving me any problem and i tried to setup it with it disabled.
For the god sake i just want to be able to watch my series again, anyone please help me! If you need any more info just ask it, i can run wireshark and send some prints if this can help too.
- edit
Tried today with an Ipad and has able to do the setup and got the screen ready to cast, however i see no ports open in UPNP, and the chromecast app on ipad said it was configured but was not possible to dectect it on my network, and also from time to time the screen would go back to 'connecting to your wi-fi' then go back to 'ready to cast' i was able to cast this table as i write this,will see if it will stay stable and come back.
On my Galaxy S4 GT-i9500 on my chromecast still says no chromecast found for some reason, but i'm able to cast from it, however i seems to get black tabs now when streaming to my chromecast which i don't like, verified the same for my Galaxy S5 , for my Ipad and for my Iphone 6, why????????? I can ping the chromecast too however i had 1% loss of packet on 200 pings in the same room as my router.

You mention you have a main network and a second network. Can you elaborate on how those are connected together?

The main network is the network of the house and the second network is the network of the backyard, but i'm trying to run the chromecast in the main network, and the second is currently off.
The main network is the tp-link router as access point to a TG862 ARRIS in brigde mode, with firewall and nat disabled.
I think my wi-fi settings are all ok right? So why the chromecast can't setup???

I'd try changing wifi channel to 1 or 6. I'm not a network expert but I'd try that.

Comcast Moden Connection

Cant get chromecast to connect to comcast modem DCP 3939 https://support.google.com/chromecast/answer/3438461 cant find these settings is there a fix or work around

My guess is that your have the modem/router from Comcast. I've learned that you need your own router as I spent weeks looks for a workaround for my in-laws.
Comcast blamed Google, which made me laugh when I connected the Chromecast on my own network and it worked. From my research, Comcast did an update to the modem/router that essentially caused the problem.
If anyone has found the solution, please share!

I have one of the comcast routers that was installed with my X1 box. Per the router info it's a Cisco Model DPC3939. It supports both 2.4 and 5 GHz.
Make sure you are connecting to the 2.4 GHz not the 5GHz (Chromecast help page says 5GHz is unsupported).
I tried rebooting router then chromecast, that didn't work.
I tried adding the mac address manually to the router and was still having trouble (router saw the chromecast as connected but during chromecast initializiation it couldn't connect to the newtork).
What finally fixed it for me was fiddling with the UPnP settings then rebooting the chromecast after. You can get to the UPnP settings by logging into the router, then:
Advanced > Device Discovery
These are the setting I have, that worked:
UPnP: Enable
Advertisement Period: 5 minutes (default is 30)
TTL: 10 hops (default is 5)
Zero Config: Enable (default is disable)
After saving those settings I then restarted the chromecast and went through the connection initialization on the chromecast app and it now connects / works
It also worked for me

Comcast has 15 types of modems, when did you get it, what does it look like?
Does the name of your WiFi have a space in it?

Just my advice...
But anyone using an ISP provided device that has it's own WiFi is using a router and should go out and buy your own then have their ISP put that device into Bridge mode.
You will have a much easier time with getting streaming and other servers to work and you will have complete control over your home network....
As opposed to someone who lives 100's or 1000's of miles away who may or may not speak your language!

Can't connect to both Cell data and Local Adhoc Wifi website

Have a Nexus 6 Rooted; Android 7.0 Stock and attempting to:
1) Stay Connected to cellular data
2) Connect via WiFi to Local Ad-Hock Network ( DHCP); "SharedData"
3)Access both WWWeb sites via browser, and the local webserver on the local WiFi ad-hock network ( @ DHCP 192.168.4.1 on SSID "SharedData")
*Constraint: Can not change webserver from current IP scheme which is
SSID: "SharedData"
BSSID: f4:55:95:11:3a:3f
Lease duration: 86400
Server address: 192.168.4.1
Broadcast address: 192.168.4.255
DNS(1) address: 192.168.4.1
DNS(2) address: 0.0.0.0
Mask: 0.0.0.0
Gateway: 192.168.4.1
IF the Cell side data connection is disabled, can connect to local WiFi network, and access the local webserver, but once the Cell side data is re-enabled, the WiFi stays connected but browser request for HTTP: //192.168.4.1 fail and can no longer reach the local webserver.
Seems to be a routing / DNS tied issue, but not sure how Android handles request when cell data and wifi are both active and handling request.
Any ideas of a configuration that preferable will not require root would be appreciated, any and all idea are appreciated.
Thanks!

Your issue is that it cant be used at the same time as they use the same hardware. As an example. When mms comes in and you are connected to wifi the radio disables the wifi connection for a sec to download it on the cell network. They both use the same antenna so only one connection is active at a time.
