I have a wireless network from which I can use two laptops to access the internet. I am able to access some web sites from my xdaIIi when it is connected with my laptop, but it tries to use GPRS to connect. All I want to do is use the xda to surf while both laptops are being used. I can connect to the network. Please will someone tell me All of the settings required for internet access.
Really appreciate any help.
Wifi the simplest to do.
I really dont know what the fuss about connecting via wifi is all about.
I am by no means a technical person on such issues but here I have tried to explain step by step to get wifi on XDA 2i & the laptop.
PLEASE DONT TURN ON THE WIFI until the steps are completed
Step 1
Click Start -> Settings -> Connections tab -> Connections -> Advanced Tab -
Select Networks -> Select MY WORK NETWORK for both (from the drop down menu) -> OK -> OK.
Step 2
This is the most important part & most people I feel get confused here becuase of some numbers involved.
Click Start -> Settings -> Network Cards -> My network card connects to: The Internet (from drop down menu) - click tiacxwln Compatible Wireless Ethernet -> Use specific IP ADDRESS
IP ADDRESS : 192.168.X.xx -> X is mostly 0 or 1 (check in the laptop),xx= any number other than the one in your laptop
Subnet Mask : 255.255.255.0
Default Gateway : 192.168.X.1 -> X = 0 or 1
-> Click Name Servers tab
DNS : 192.168.X.1 -> SAME AS DEFAULT GATEWAY
ALT DNS : CHECK LAPTOP,put in the same numbers (not necessary to fill)
WINS : 192.168.X.1 -> SAME AS DNS & DEFAULT GATEWAY
Here is my settings in INDIA.
LAPTOP XDA 2i
IP ADDRESS : 192.168.1.32 IP ADDRESS: 192.168.1.33
Subnet Mask :255.255.255.0 Subnet Mask:255.255.255.0
Default Gateway: 192.168.1.1 Default Gateway:192.168.1.1
DNS: 192.168.1.1 DNS: 192.168.1.1
ALT DNS
WINS :192.168.1.1 WINS :192.168.1.1
Please remember these are the settings for India .I think 192.168 is common through the world I guess ,only the last two numbers are different,i dont know
STEP 3
Click Start -> Settings -> WLAN -> turn on by clicking the [w] in the bottom
voila!!! (I HOPE ) Connected to NETWORK appears in STATUS.If you are using a WEP key on the laptop ,use the same key on the XDA 2i when prompted.
(If the network connection doesnt appear as connected in status)
Below the Main,Settings,LEAP tab there are 2 icons - PDA & W
click on the PDA icon
Configure Wireless Networks appears under which find your network & click on that
Network Name :
Connects to : WORK
Click Network key tab
Authentication : OPEN,SHARED among other choices in the drop down menu.(If you dont know then look it up in the laptop under wireless connections )
Data Encryption : WEP (MOSTLY)
(unselect the key is provided automatically if it is ticked)
Network key : ********(The WEP key as you enter in the laptop)
Key Index : 1
click 802.1x tab
Tick the selection & select PEAP from dropdown menu.
OK ->OK -> OK
FINALLY
CLICK START -> Programmes -> Internet explorer -> HAPPY SURFING
P.S - Must agree easy to do but tough to explain .
Nicely explain by nannlp
For me, just follow the Step 1 and after that turn ON the WIFI and get connected....
Most of the time, leaving your wireless adapter settings configured for DHCP will work fine - you just make sure your wireless profiles are set to connect to the Internet (when it finds a new network, it shows the box "which does this connect to?" and you have the choice of Work or Internet) and it should work fine, provided you don't have any hardware issues.
You can have hardware issues, though; my Alpine can't connect to some wifi routers (such as the wifi-enabled Thomson SpeedTouch 780WL modem/router which my ISP gave me, and which I HAVE to use to access the Internet at home) - it'll connect to my Linksys router fine, but that has no modem in it (I'm using it as a wireless repeater) but it just passes all traffic to the SpeedTouch anyway, so the SpeedTouch assigns IP addresses and does all the configuration work when new devices connect, and I've had problem elsewhere too - the device either doesn't connect at all, or it connects but then just goes round and round in circles not connecting properly.
It's a pain in the arse, and it's definitely a hardware fault (I've tried Hitchhiker and various other apps to try and make the device connect, and I can only get as far as "assigning an IP address" and it falls over). My new Hermes works fine on everything though, so I assume it's a definite hardware flaw.

Thanks for advice councils guys
i REALY dont know why you need to run though all those setting, just turn your wifi on using the tab at the bottom right of the screen, then click on wirless manager (bottom left a square with a W in it), then the wlan icon to trun on the wifi, click on settings, its bottom right looks like a phone with a wire. find your wifi network and hold on it then click connect, if it comes up with network type, chose interet. then enter your wifi security key if needed, click okay and go back to main, then u can surf the net all you want the next time u just have to turn on your wifi and it will auto connect.

hy, last week I've bought an unbranded Qtek 9100. I flashed it with the latest Mr. Clean ROM, works without problems, the only thing is that i can't use the wifi anymore. My phone can't find my network or it can't connect. With the older firmware there was no problem. I've tried several things such as unsecured wlan etc but it will not work anymore. Even to downgrade the firm isn't possible.
Any suggestions???
Same
The same thing has happened to me. I have a Belkin WiFi router and with this ROM it sees the router but cannot connect to it.
Wireless LAN Configuration
For those having problems with their Wireless Home Networks with or without the ROM update, here are the instructions. Loads of the ones on the Internet are not very clear. Try those first If you like otherwise try this, I tried to make it easy I hope.…
Wireless LAN Configuration
Start Menu -> Settings -> Connections Tab -> Connections Icon
Select Advanced Tab -> Select Networks
Change the first dropdown to My Work Network
Change the second dropdown to T-Mobile GPRS
Click Edit on the My Work Network dropdown -> Proxy Settings Tab
Check the first box (This network connects to the internet), but NOT the second (This network uses a proxy server to connect to the internet)
Now do the same for the T-Mobile GRPS settings in the edit menu, only check both boxes this time. For UK type in 216.155.165.50 as the proxy server.
In ZoneAlarm… (or other firewall I guess)
Allow 169.254.0.0 / 255.255.255.0 as Trusted Subnet
Allow 169.254.2.0 / 255.255.255.0 as Trusted Network
For ActiveSync make sure all its 4 exes have full access to Internet, act as Server and send mail are all ticked.
All should be working ok now.
Got the same problem... Yet only WPA-protected networks fail - unsecured works fine. No luck with twiddling the settings your way or any other.
I'm confused. My IE instance quite happily connects to my 3G t-mobile connection when no connections are enabled. However, when I enable the WiFi - the little mast icon says connected... but IE can't find anything. I'm assuming its a DNS issue. I've tried disabling MAC address security, and it made 0 difference to the failure to connect - so I'm assuming the MAC address I typed into my router was the right one. (Can't even find the TyTnII MAC address now!)
So - what do I need to do to ensure that the TytnII loads the WiFi connection when at home, and actually allows me to surf? I tried putting in the router address as DNS - and it didnt make any difference either. What next? Too many options!!!!
Graham
If its over a wep network(which it probably is) you need the key(passcode)...
Nope - got that - (and it only prompted for the passkey once - so I guess it stored it somewhere). Its got something to do with DNS - because it cannot resolve names (like google.com!) - but I don't know how to check this out. Are thetre tools like TRACEROUTE / IPCONFIG etc for WM6??
Graham
Try removing any proxy servers that might be configured.
Go to settings/connections/wi-fi and tap your connected Wireless Network to configure. In next screen check if "Connects to:" is set to "The Internet" . If set to "Work" IE will use your 3G dataconnection. When set to "The Internet" IE will use your WI-FI connection. When you are outdoor and your home WI-FI connection is not available IE will then automaticly use your 3G connection again.
Hope this helps as it works this way with me.

Does your WiFi network use a proxy to get to the internet?

Hi there,
Can someone please help by advising me on how to overcome this problem.
If I broadcast my SSID, the device connects fine, but when I stop broadcasting, the device will show that the network is unavailable. Even though I did check the "This is a hidden network" checkbox option, in the settings.
Configure Wireless Network-
Network Name: MyWirelessNetwork
Connects By: The Internet
This is a hidden network: CHECKED
Configure Wireless Authentication-
Authentication: WPA2-PSK
Data Encryption: TKIP
The Key is Automatically Provided: unchecked
Network Key: **********
Key Index: 1
Please help,... many thanks!
Kind regards,
JonD
My device is the HTC TyTn II (Kaiser) running Windows Mobile 6 Professional
Additional information about my WiFi Router:
I'm using a D-Link DI-524 wireless router that I set as a hidden network (disabled SSID broadcast).
I also enabled the MAC filtering, and of course the device's MAC address is already added to the approved list for connections, so I think there is no issue with the router or network (like I mentioned before, when I enabled the SSID broadcast all devices connect perfectly and all is good, but when I disabled the SSID broadcast, the Kaiser & the vista laptop will say the network is unavailable and can't connect).
No problems with connections at all with my other laptop that runs on XP.
Stupid question...but are you able to connect to the network with another devcie. Also have to tried running a third party program that can scan for wireless AP's from the device.
And can you connect to any other hidden network..
It might be in a really good hiding spot.

Somethings wrong with what you posted. WPA2-PSK is a form of authentication, and it would use either AES or TKIP as it's method of encryption. There is no such thing as a WPA, open network (WEP, open yes, but not WPA).
gwnorth, thanks for pointing that out.... the following is the correct configuration:

As for the other questions (for Arlop & ChumleyEX), I've got no problems connecting to my non-broadcast SSID network with my laptop running XP.... but I face the same problem with my other laptop that runs on vista.
of course, when I enabled the SSID broadcast, everything connects fine (the Kaiser and the vista laptop).
If anybody faced this similar problem and knows a solution, please let me know. Appreciate your help in the matter.
What is the point to have the system acknowledging that the network is hidden or not (checkbox option "This is a hidden network:" CHECKED or UNCHECKED ), but still fail to connect to it.
cheers,
JonD.
I'm not sure if this will help ...
I'm using a Netgear wireless router provided by my company which is set to an hidden network.
To set up access via my Kaiser I enter:
Setting > Connection > WiFi > Add New ...
Network name > Mynetworkname
Connects to > The internet
Hidden network > Checked
Authentication > Open
Data Encryption > WEP
The key is automatically provided > Un-Checked
Network Key > ****************************
Key Index > 1
What you haven't mentioned, but something that I needed to do ... The router needs to know my PDA mac address to allow access in its settings to support authorisation.
Since our IT department control the access rights (unless you have the password ), I do not know if the mac address information is a company protocol or part of a 'hidden network' setting.
PS. I always keep the WEP key in a text file on the PDA to copy and paste, because it's too troublesome to type it out each time I change the ROM's and have to set it up again.
I hope this helps.

Sounds to me like you have a network issue, not a Kaiser issue since you said your having the same issues on Vista.
I do not broadcast my SSID and my tilt has no problems connecting.
Maybe you have MAC-address filtering enabled?
I have seen routers giving problems with MAC-filtering disabled and SSID broadcasting disabled.
Devices that had a working connection, disconnected when we disabled SSID-broadcast.
Strange, but enabling the MAC-address filter list solved that.
To ajs007, jallenclark & johanromijn thank you for your replies.

ajs007, do you think different authentication protocols (you use WEP, but I use WPA-PSK) make any difference?
jallenclark, is there anything you did differently?
Thanks.

I have the same issue with mine. I cannot connect to a hidden network....initially.
I turned on SSID broadcast, the Tilt connect immediately and then unchecked the SSID Broadcast.
Now it connects always.
Seems like it should work.. other devices connect fine as long as the name is specified.

Sadly, I tried that, connects immediately when the SSID is broadcast, and while it remains connected, I turn off the broadcast and the device lost connectivity immediately too.
Man... I don't understand this......
here are some more info (ROM version and stuff), just in case you guys out there can help figure this out...... many thanks!
ROM version: 2.50.771.0 WWE
ROM Date: 10 March 2008
Radio version: 1.27.15.32
Protocol version: 22.51.88.13H
I have similar problem, Hermes with wm6.1. When my router is set up to use WEP I have no problem to connect, but I prefer WPA2-PSK and my PDA gets stuck on "connecting".
My iBook and a PC laptop can connect without problem...and so does my buddy's iPhone...
Change the radio version. try flashing a radio that end in 36. xD
i have similar problem with my x1. radio version ends with 18. firmware version is R2AA010. exists one with newer radio? thx.
Works on mine?
I went to a customer site recently where they were deploying a Wireless LAN. As they were using a hidden SSID & WPA2-PSK & AES I tested it with my Kaiser and after a couple of attempts it connected OK (I think typos on my part were why it took two attempts..).
Hidden SSID's are pretty useless anyway as they are easy to discover. I think beefing up the back end security is a much better option - use WPA2 with PEAP or EAP-TLS instead of just hiding the SSID and using Pre-Shared-Keys. If the key is leaked then think of the number of devices you need to manually reconfigure.

Hi,
I have ADSL modem, and I am trying to connect to the modem (via WiFi) and use internet on my HTC VIVA.
My internet connection requires authentication in order to connect. I can successfully connect to modem using Wifi connection. In order to connection to Internet, I added new VPN server from settings > Connections > Edit my VPN servers. I added all the credentials as provided by my ISP, however I am not able to connect to internet and access web pages from the Internet explorer of my device.
Please help me and let me know where I am going wrong?
Thanks,
You don't have to set your authentication data in your Viva.
All you need to do is connect to your ADSL modem using WiFi and start browsing the web. It should work correctly unless your ISP requires a proxy server.
Tell us what happens.
Hi GFX,
Thanks for replying. I connected to ADSL using WiFi, but when I open Internet explorer I get page not found.
When I was in US, I was able to access Internet as per your reply. But now I am in India and I am not able to access Internet.
Some of the differences that might help you or any other who would like to contribute
USA India
====== =======
ISP Comcast BSNL
Authentication WPA2-PSK Open
Data Encryption AES WEP
Thanks,
I'm not sure what's causing this.
Probably your ISP requires a proxy server. Can you connect to the internet using your PC??
The other thing is, your ISP has nothing to do with your ADSL modem authentication and data encryption modes! You can set these settings manually according to your personal needs. Read your ADSL modem user manual for more information.
A WPA2 authentication is recommended so you can protect your modem & internet connection from outsiders and hackers.
Check your ISP's website to see if they require a proxy server. And tell us about your ADSL modem brand and model so we can help you.
My ISP does not require proxy server, and I can connect to Internet using my PC. I am able to connect to my ADSL modem but somehow I am not able to connect to Internet.
Following are the details of my ADSL modem
Brand: Huawei
Model: WA1003A
Its an ADSL router.
Thanks,
OK, please check the following settings in your device:
1- Goto Start-> Settings -> Connections -> Connections-> Advanced tab-> tap on "Select Networks", and check that the first dropdown menu says "My ISP".
2- Goto Start-> Settings -> Connections -> Wi-Fi -> Network Adapters tab, and check that the first dropdown menu says "The Internet".
If you made any changes to the above settings, try to reconnect to the modem once again, it may work this time.
However, if you left the above settings unchanged then your problem lies somewhere else. Check if you can access the internet using Opera Mini, or try connecting to another router. Because we need to determine the source of the problem.
Good luck.
have you simply tried connecting via wifi with default settings?
when you switch on wifi, once the network is detected, you can feed in the values then right? sorry if this seems like a stupid answer but we often miss whats right under our noses,
Sorry for replying so late, was busy with lots of work for some time.
GFX: My connection settings are same as you mentioned. But even with these settings in place, no success.
karthiksk: I get connected to WiFi network, but after this I don't get any popup box in my device to enter the details.
Guys, however I got the solution, since my network uses PPoE, I had to configure these settings in my Modem. Earlier I was entering ISP credentials in an external PPPoE client on my PC, this way I can access Internet with only one PC at a time and WiFi was also not working.
I entered ISP credentials in my modem and configured PPoE settings. Now I can connect my PC (using Ethernet cable), my laptop using WiFi and my HTC device using WiFi at the same time.
Thank you all for helping me in trying to resolve this issue.
Good to see your problem solved.
Turns out it has nothing to do with your device!
Enjoy your Viva, it's a wonderful device.

This is a Windows Mobile and HTC VIVA forum, it is highly unlikely that you will get your solution here. and it is unsafe to post you mobile number.
I'm facing the same problem..it's not the ISP or modem..it's only & only viva...
It sucks badly...I purchased two different modem router..one of netgaer and other one of linksys...and the didn't work on both of them...wifi only works with the modem ZTE ZXDSL 531B
**** off viva...
hey guys ..
i can't think of any reasonable reason why it's not connecting to my router !!
i'm using my wifi connection with many laptops ..
and the GalaxyS was working properly yesterday too !
but now it's not working .. it finds the network and start obtaining IP adress for it but it can't , it just try to do that again and again
i assume that there is a password...you tried re-entering the password?
if so and still not working.
what did you do in the phone yesterday before it stopped connecting?
installed anything new?
yes there is a password .. i tried to enter it again
and i tried "forgetting this network" and start the connection over with no result
i didn't install anything new, but i updated some of the programs i have !
What ROM are you currently on ??
i have had this issue many times with darkys ROM
i'm using an official one ,, the one came with the phone (Froyo)
thats weird....
what about the kernel ?? or is that stock too ?
stock too
2.6.32.9
[email protected] #53
hmmmm........
i dont know how to help you.... whenever i get this problem i re-flash the kernel / modem / ROM.
I think you may need to do a factory reset, in order to get the wifi back. BUT !! to make a full backup you will need an app like 'titanium backup' which requires you to be rooted.
I can pretty much guarantee a reset will fix your problem.
Also if you dont fancy going on to a custom ROM, have you checked your up to date with KIES for the latest firmware ??
ok if i backed up my data ,, will it back up my apps too ??
or only emails, msgs and numbers ?
titanium backup will back up all your apps and app data and settings.
then after the reset, re download from the market and do the restore and hey presto !! job done.
ok i'll try that and i'll let u know
it worked .. thanks
well done thats good news !!
Reboot
I sometimes get this problem, too. I'm on stock ROM and kernel. When it happens I simply reboot the device and problem solved!

Try this.
Firstly, what brand of router do you have in your house? You need to find out if the router itself has restrictions on how many 'clients', or devices, it can have connected to it at any one time. To know what brand of router you have also helps with what the "Internet Protocol' (I.P.) address it has. It should be something like,
192.168.0.1
or
192.168.1.1
or similar. You will find out this information, on a Windows computer that's connected to the router, by clicking the Start Button, and where the 'Search programs and files' bar is at the bottom, type in (without quotes) 'cmd' and press Enter. At the prompt, type this exactly:
ipconfig /all
and the IP address of your router will be shown next to 'Default Gateway'. You then type those numbers only into the address bar of Internet Explorer/Firefox/Opera/Chrome and a pop-up will appear asking for Username and Password. Username is often
admin
and the Password is either
password or admin
You can then look for Wireless Settings that will show you if there are restrictions on how many actual devices can be connected to your router at the same time. While you are in the config of your router, it's a good idea to have researched the Primary and Secondary DNS (Domain Name Server) addresses of the Internet Service Provider you are currently signed up with. Just Google 'your internet service provider's name' along with 'DNS settings' and you will find the info you need.
You can then input those details into the router directly through the Settings menu, and change it from constantly seeking a domain to a situation where the router knows exactly where to look for the internet. This can speed up your internet a bit. With all the info you've grabbed, you can also set static (permanent) IP's for every client (computer/device) that's connecting to the router, making the whole network in your home faster.
Okay, now to your Galaxy. If your router is allowing a large number of clients on board it's wireless network, then it's a case of your Galaxy and the router not talking fast enough about assigning an IP address to your phone. The way you fix that is quite simple, assign a static IP to your Galaxy. With wi-fi turned 'On' on your Galaxy, go into Settings/Wireless and network/Wi-Fi settings. You'll see the name of your network there, and it should say something about 'obtaining IP address'. Now, here's the fun part.
Click on the left soft-key, and you'll see 'Scanning' and 'Advanced'. Click on 'Advanced', and a new menu will open. Down the bottom, you'll see 'IP settings' and under that, 'Use static IP'. Put a check in that box, then click on 'IP address' (below the checkbox). A little window will pop up, asking for an address. You now need to put a value in there that's similar to your router's IP.
Example:
If your router's IP is 192.168.0.1, then you type into the box 192.168.0.3
You need to make sure that the last digit (or digits) you use is different from any other computer using a static IP that's connected to your router.
Once you've clicked OK, scroll down a bit and you'll see more options. You need to tell the phone what 'Gateway' to use. That number is the same as what you found when you looked up the IP address of the router. Next, 'Netmask'. That's 255.255.255.0 Now, 'DNS1' and 'DNS2'. They are the Primary and Secondary DNS addresses for your Internet Service Provider, that you researched earlier.
Now you should find you'll connect to your router a lot easier, and have a more stable connection. Note, however, if you go roaming about and try to connect to a wireless 'hotspot' somewhere else, you'll need to go into the same area of Wi-Fi settings and turn Off Static IP in order to connect to the 'hotspot'.
Hope that helps...
