i can connect to a access point, but when i try to open internet explorer n try to go on a site it always says page not found after few seconds
but when i got bak to setting - connections - network card - the phone is still connected
i also tried using WiFiFoFum, which locates the access point, click on connect but nothing happens.
can anyone tell me where am going all wrong?
Are you definitely getting connected to the access point - are you getting an IP address? (Check your wireless lan IP settings in the "settings/communication" program, and look in the "advanced" tab)
yes am definetly connected, cuz i keep chekin on "network card" when it keeps failin to load up n it says connected there and also get the IP address as well, signal strengh is just about 60%
Did you make sure your connection /network card is set to connect to 'the internet' ?
I found that makes a difference on mine...
it always has been set to "the internet"
I have the same problem guys.
It seems like it's looking for a modem connection and does not use the existing WIFI connection. This s*cks. :x

Have the same problem
I have the exact same problem, any help very welcome.
easy fix, your going to kick yourself. go into the wifi setting where it shows battery setting efficiency and move the bar to the left for "most efficient". it fixed it on my qtek. let me know if it worked
i manage to keep the connection stable after tweaking the wifi settings to performance boost to max instead of power saving mode..
give it a try...
go to settings, select wireless lan, select the power mode tab, slide slider all the way to best performance instead of best battery.
every webpage loads up after i do that
Connection still not working
Hi, moved the slide to best perfomance.
Still can't ping the gateway.
- The manager shows me connected to the network
- The device has a IP
- I can see the device on the router
but still no connection to the other machines or the Internet.
I'm pretty shure I did a config mistake...
Thanks for help
I had the same problem too. I found the answer a few days later after few tries.
I couldn't find the help here, and I wished someone had the answer. Now that I have the answer I am sharing it with you. It's the real answer.
If you have wireless protection, you'll need to set up the connection correctly with your key and your personal WLAN IP address. Once you've setup your WLAN connection on your Wizard correctly, the Wizard will tell you if you are connected or not. That's the easiest part.
Ok, now when you go to IE on your PDA phone, it might just go to a local webpage stored in your PDA memory. When you try to go to an actual internet address like yahoo.com, you get an error message. In that error message, you'll get an option to be linked to a full explanation from Microsoft on how to setup IE properly. You can screw the explanation, and dump this information away for your WLAN setup.
What you really need is to setup your DNS, and alternative DNS. To do that, you'll need to know your DNS, and alternative DNS. If you don't know it, call your ISP, DSL or Cable company to get those information.
To set it up, you go to CONFIGURE NETWORK ADAPTERS >> SDIO WLAN WIRELESS ADAPTER >> NAME SERVERS.
BTW, the Wifi connection is extremely slow. So don't be surprised to be disappointed after all your work. I mean you won't even bother to use it in the bathroom because you'll be done with it, seriously!!!
Good luck.
I just bought the new T-Mobile (USA) MDA a couple days ago, a version of the HTC Wizard.
I have been able to connect with GPRS/EDGE, and seem to be getting EDGE speed, which is nice (my first EDGE phone).
However, no such luck with Wi-fi.
At my house, I can easily connect, at all times, with a few different wi-fi networks, with my wi-fi enabled laptop, and with my older PPC--an IPAQ 2210, with Spectec SDIO Wi-Fi card, can browse the web via Wi-Fi, etc.
The MDA does connect to Wi-FI, appears to be connected to it. (After turning it on in Connection Manager, of course.) But I cannot access any web sites with it. On trying to do so with PIE, I always get the error message:
"The page cannot be displayed or downloaded because the connection was lost, Check the connection and try again later."
I have not once been able to access one web site via Wi-Fi, with the MDA.
Can anyone help with this?
Thank you.
I ahve the same problem and have not figured out how to solve this...
Can anyone help us?
same problem here, also with t-mobile as provider. can it be a problem related to t-mobile???

I have exactly the same problem
I guess you could try going under "Settings" "Connections" "Network Card" and make sure your network card is set to connect to "The Internet"
Select your wireless card and then make sure the drop down says "The Internet" and hit ok.
Also, make sure your GPRS Connection settings aren't setup to use T-Mobile's proxy. When your gprs is setup to use a proxy for web browsing, PIE will attempt to use the proxy with any connection. And by proxy, I'm not talking about an APN or anything.
Are you running security on your router? If so try shutting it off to test or try to connect to someone elses WiFi network to test.

I spoke with a TMob customer service rep about this a couple weeks ago, and this is basically what he told me to do. A T-Mobile HotSpot (Starbucks, etc) should work without making any changes. But if you want to use your own WiFi connection, you have to do the following:
Start Menu -> Settings -> Connections Tab -> Connections Icon
Select Advanced Tab -> Select Networks
Change first dropdown to "My Work Network".
Click OK, OK.
Then when you want to roam with GPRS/EDGE again, you have to change it back to "T-Mobile GPRS".
Very annoying to say the least. If anyone knows a better way to do this, I'd love to hear about it.
This works for me:
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
Make sure My Work Network is set to connect to the internet, but has NO proxy settings.
Make sure T-Mobile GRPS is set to connect to the internet, but HAS proxy settings.
Magic!
frycow, you rock!!
That worked perfectly!! I hated that I had to keep switching networks whenever I wanted to go online via GPRS or wifi!!
Thanks!!!
frycow,
wow. that sounds great. but I can't get it working. could you take a couple minutes to walk me (and I'm sure others too) through your exact settings? especially the proxy settings.
thanks!
frycow is a freakin champ....that did the trick!! I've been WAITING to get this working!!
AHHHH, AND IT FINALLY GOT MY POCKET MSN TO START WORKING TOO!!!! Still doesn't work on GPRS, but it certainly works on Wi-Fi!! I suppose the last thing would be to get it working on both!! regardless, this is SWEET!!
I can´t get it working :evil:
When I Change the first dropdown to My Work Network and after that tryn to sync without having wifi enabled, the device does not connect with GPRS..., solutions...
frycow, hazchem, djswivel:
Could one of you help out Paltkugen and I? Both of us can't get it working. If you could let us know the specific settings, including the proxy settings, I would really appreciate it. Its so frustrating to know it works for some people, but not being able to get it going.
Thanks!
I did EXACTLY what fry posted....follow this carefully
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 settins in the edit menu, only check both boxes this time. Then type in 216.155.165.50 as the proxy server. From there you should be good.

That is exactly what I did too. Just tried it again and I can't use GPRS to surf. I have Wifi turned off. GPRS is not connected. I open PIE and go to some URL (google.com). GPRS starts connecting and successfully connects to T-Mobile GPRS.
Then, for about 30-60 seconds, the status bar says "Locating". Then an alert pops up that says "The page cannot be displayed or downloaded because the connection was lost. Check the connection and try again later."
Next, I turn on WiFi. It conects to my local WiFi network. It is still connected to T-Mobile GPRS too. I go back to PIE. As soon as I try to goto a URL, the GPRS connection drops, and again it says "Locating..." for a while. Then the same alert pops up again.
So now that GPRS isn't connected and just WiFi, I try going to the URL again. Same results.
Next I try turning off WiFi. Now there are no connections. I restart WiFi and there is just a WiFi connection. Same results in PIE.
I thought maybe the proxy is the problem, so I turned off the proxy in GPRS. When I do this, the checkbox "This network connects to the internet" won't stay checked. Even if I check it and click ok, when I go back it is unchecked. And when I did this, I couldn't even connect with GPRS. And with WiFi on, it would connect to Wifi, but going to a page would immediately pop up an alert that says "Cannot Connect with current connection settings. To change you connection settings, tap Settings."
I added the proxy back in and then tried changing the GPRS access point name from wap.voicestream.com to internet2.voicestream.com and internet3.voicestream.com. internet2 wouldn't even make a connection, but internet3 did. however, i still couldn't locate pages in PIE. So I changed it back to wap. I think my unlimited GPRS plan is configured the VPN way, so I remember having to use internet2 or internet3 in the past.
Could the proxy server not be working right for me? Is it possible that I cannot locate the proxy because I'm configured in a non-standard way (with a different access point - internet3) than most?
I think I'll call tmo and see if I can get changed to the regular AP (wap). I'm not using VPN stuff right now anyway. If anyone has other ideas, please let me know.
Thanks again!
I think i have a work around. but involes changing it back and forth when switching btwn wifi and gprs..
created two connections.
one with proxy and one without.
im only able to surf gprs with proxy.
when connecting via GPRS set both networks to connect to PROXY.
when using WiFi, set both networks to connect using NOPROXY.
that should work. at least it worked for me. tried only 2 pages and it loaded for both. GPRS used myvoicestream and wifi google.

Earlier today I had been trying to get VM Net Browser or Resco File Explorer to work, and they *were* working, albeit very sporadically. Sometimes I could see whole windows network complete with shared files and directories, other times I could browse to my computer and it wouldn't show anything as being shared. Looking for a solution, i found this thread.
I followed the recommendations of the previous posts and got exactly the same results as yowzator, including the weird thing with the "This network connects to the internet" checkbox unchecking. My GPRS access point is also named wap.voicestream.com - not sure if that matters.
However, I know that I was having at least partial wi-fi success before trying this fix or I wouldn't be able to have seen my home network. So I gave up on this fix and put everything back to the default - GPRS for programs that automatically connect to the internet, no proxy, and My Work Network for programs that automatically connect toa private network, with "This network connects to the internet" unchecked because it's impossible to check it and expect it to stay checked.
I tried surfing around to a few pages with wifi only (connections shows me connected to my network, I turned off the phone icon in the comm settings, and tapping on the connectivity icon on the taskbar didn't have GPRS listed) and amazingly, some of them worked - though the "locating" process seemed to take a while, they sometimes seemed to load faster than with GPRS (especially if I let my MDA go to sleep and then turn it back on again).
And then they don't work again, without me doing anything. So I don't think the fix we've been trying is a true fix to the problem - if it was then then pages would *never* load with the proxy disabled. Right?
I've been wondering if the "modem" tab under My Work Network is supposed to be blank . . . even if it's using wifi it seems like a poor UI design to not have a checkbox or something saying "this connection is for wifi and not dialup".
I am using the 2.17 ROM update. My wireless router is a D-link DI-624 extreme g. I'm using WEP encryption.
I am crying . . . tears . . . of confusion.
SOLUTION!?
This works for me (suggested in another thread):
1. Add the following to the registry:
HKEY_LOCAL_MACHINE\COMM\TIACXWLN1\PARMS:
DWORD dot11SupportedRateMaskG=8
(Note that there is already a key in the registry called "HKEY_LOCAL_MACHINE\COMM\TIACXWLN1\PARMS: DWORD dot11SupportedRateMask=1" - you should leave this alone)
2. Do a soft reset.
3. Go to your wi-fi settings -> Power Mode tab -> Best Performance (without this step it didn't work for me)
4. Turn on wi-fi and connect to anything in internet explorer. It should seem blazing fast compared to GPRS.
Note that this assumes you haven't done any of the fixes in this thread. That is to say, leave it with GPRS for programs that automatically connect to the internet (with no proxy), and My Work Network for programs that automatically connect to a private network, with "This network connects to the internet" unchecked because it's impossible to check it and expect it to stay checked.
So far (for a few minutes anyway) this is working for me! Even Resco File Explorer seems to mostly work - I can map my PC's shared folders and see my stuff reliably, as far as I can tell. VM Net Browser is still wonky though.
The thread this solution comes from is http://forum.xda-developers.com/viewtopic.php?t=38898&start=0&postdays=0&postorder=asc
Hi,
tried that solution
(I have a thread below)
still falls over on "locate".
I have no home network so I have never got anything working - connects fine on a public hotspot, but as I say, fails on locate.
I've had enough - may either phone T-mobile pay CS - something I really don't want to do out of principle - or just send teh phone back.
any new info on this? can seem to get it to work.
i have configures it many ways as suggested above. only time i was able to browse on wifi was with no proxie was set up. i connect through another network, (the mda automatically hooks you up to all avalible networks) but that only lasted a few minutes.
is there even a chance i could someone at tmobile even help me??? anyone here call them and get got service/help with getting it to work?
thanks

Hi,
I've just got a T-Mobile Vario. It connects fine on GPRS and PIE navigates to web pages.
I then try to connect to a free WiFi hotspot (I have no home wifi network to test on).
It *connects* fine. However, when I try to navigate to a web page it hangs on the "Locate" message, then times out.
I have searched the forum and read similar problems but with home networks not public hotspots- for example:
http://forum.xda-developers.com/viewtopic.php?t=46118
I tried the solutions suggested there but with no luck. Has anyone had similar problems?
I *really* need to get WiFi working (by the end of the weekend hopefully) as thats what I got the device for in the first place.
I am a WiFi virgin so any pointers will help.

Cingular 8125 WiFi fails
I have the same results. My router assigns my device an IP address with WiFi on, but I get the message "...the connection was lost." whenever I try to surf internet. If anyone understands how to set it up, we'd appreciate instruction that works (I'd like a Cingular user if possible) but I would also like to learn what the settings mean. Anyone have a link to network setup information? I have a WiFi network in my home which works for my wife's laptop and my old PDA. This 8125 is bugging me.
working now...
OK, as soon as I posted and went back to the PDA the WiFi connection now works - gremlins again... I didn't change anything or even soft reset - it just connected. I wonder if it was because the GPRS connection ended... I'll try turning off my automatic e-mail checking and post again. BTW, I am using the suggestion of the first Network being "work - no proxy" and the second being "MediaNet - proxy"
Your problem doesn't seem the same as mine.
I have no home network.
My vario, on a public hotspot, always "connects" but always fails on "locate".
you need to make sure the connection is not using a proxy server.
go into settings
connections
then manage existing connections
untick the checkbox on the proxy settings tab that says this connection uses a proxy (or words to that effect)
now you should be able to connect to the network as long as their is no security in place to stop you.
good luck

Hi,
I have no "manage existing connections"
under settings->connections.
I go into connections which gives <tasks> and <Advanced> tabs
Under Advanced> I have <select networks>
This screen "Network Management" has two drop downs
1 states "Programs that automatically connect to the internet should connect using"
"T-Mobile Internet" is selected
If I edit and look at proxy settings it has:
"This network connects to the internet" ticked
the proxy server box is empty
If I edit the modem tab it has Cellular Line (GPRS) selected
Dropdown 2 has
Programs that automatically connect to a private network should connect using:
the dropdown is filled with "My Work Network"
By default the "connects to the internet" box is empty. I have filled this in previously with no luck.
Modem is empty as are all the other entries.
I have swapped the order of the dropdowns, I have made both "My Work network" and both "T-Mobile Internet" with no luck.
I have tried the suggestions on the thread I referenced above - again with no luck.
To repeat I can get the "connection" up. When I select the network it states connection is "good" yet when I try to surf to a page it craps out on the "Locate" message.
Is it failing to find a DNS server on the wifi link?
I'm just guessing as I know v little about WiFi as I have never used it before
TIA for any further contributions
I just wanted to say I have this same problem and have not been able to solve it yet. I can't tell whether to use GPRS while using Internet, or whether I should have the connection set to "Work" or "Internet" or what.
I have tried with 3 unprotected wireless networks already and have gotten the same results with each. I suspect it may be due to DNS. Hopefully it is not the phone itself.
Hi mat,
Well it can't be that you *must* use GPRS whilst surfing - thats what WIFI is for!
I suspect (no real evidence)T-Mobile have somehow crippled the OS to make it difficult to work out how to get free hotspot access working properly. Looking at their site they say CS do not "support" WIFI access problems - how convenient!!!!!
Although I am a WIFI virgin/idiot, I am not a *total* idiot and would have been able to get it working if it was completely straightforward.
To add ammunition to this opinion, I do not have a T-Zone account (I should have but it hasn't been set up correctly). Anyway I tried to connect though a t-zone and it worked straightaway presenting me with the login page. I could also download data - the terms and conditions.
However, obviously I couldn't surf to totally check it out as I couldn't login.
I wish someone would provide a definitive solution as it is really irritating me now!!!!!
Why would it be hanging on "locate"? I imagine it must be because it cannot look up the IP address through the free WIFI link. I made the same suggestion as you did earlier something to do with the DNS setup.
Thats as far as I can get!!!!!
I just really started playing with my T-Mobile MDA today. It still has the stock firmware from T-Mobile.
When I'm at home I like to turn the phone off and just use the wi-fi on the device. The phone sees my wireless network (802.11b) and I enter my encryption key. The phone connects to my local network and gets a valid IP address. However if I try to use Pocket Internet Explorer to navigate to a web page it never works. It always says "Locating..." and eventually says that it cannot open the page. GPRS works fine.
I have T-Mobile's internet3 APN for my GPRS so I don't use any kind of proxy for it so the trick of having a proxy for GPRS and none for wi-fi won't work for me becuase both have no proxy.
I have Linux as my firewall/gateway system so I told it to show me the packets it's getting from the phone when I try to go to a web page. It looks like the phone is correctly looking for the default gateway and my Linux system responds with what it is. However the phone keeps asking and eventually gives up. It then sends the DNS request to the broadcast address and that will not work so it's unable to resolve any names.
This looks like a pretty serious bug in the software of the phone. I've seen other threads where people mention the same problem but no resolution really. Does anyone have any suggestions? I'm guessing my only resolution for this is to try new firmware. This is pretty annoying since this is basic functionality (the low level network stuff).
First is your phone a mda vario = htc wizard or mda = htc wallaby? you may be in the wrong forum but a simple suggestion if it is a mda vario is try it on wifi g mode fix is here (only for vario) http://forum.xda-developers.com/viewtopic.php?t=38898
My phone is the Vario. I actually have a custom ROM that has the enable for 802.11g but I went into the registry and turned that off thinking that was part of the problem because I have an old Netgear access point that is strictly 802.11b. I just tried unplugging the access point and plugging it back in. The phone connected to it for a minute and then suddenly the network went "unavailable." Now it won't connect anymore. This is driving me crazy! I am running the 2.21 custom ROM that's put together by another member here (sorry, I can't remember the name). I wish there was a way to get some diagnostic information from the MDA and maybe I could better see what's going on.
Did it connect with the original rom? and maybe its better to try qtek or imate rom like most of the vario users who have upgraded are using. (which will default to wife b mode)
The original T-Mobile ROM did not work very well either. It continually asked my DHCP server for an IP address and it replied but it just kept asking.
Can you make a ROM recommendation for what you're referring to? I've been through the FTP site here and there are a dizzying array of ROM choices.
Most vario users seem to upgrading to qtek 2.17.7.2 ROM here you can download ftp://xda:[email protected]_2170702_21707102_20710_QTEK_WWE_Ship.exe
user name xda, password xda hope that works for you.
Given that's a generic ROM is there another package that will install all of the US T-Mobile settings?
There are cab's available to install GPRS, MMS settings etc but to be honest it is just as easy to do it manually (many websites give these settings) - I did it with my qtek, came with no settings - did it manually for O2 UK.
I've got the same problem with my home WiFi.
Panera - Good
Starbucks - Good
Home - Not good.
Like the others. I put in the WPA passphrase, connect to the home network, and wait, and wait, and wait....
Now, in some cases I've been able to hard code my ISP's DNS servers into the WiFi card on my MDA and soft reset and presto. Working. But after that if I disconnect the WiFi and go GPRS, doesn't work, because my ISP's DNS servers aren't accessible from the T-Mo (Voicestream) network.
Any help would be good.
In case you've not tried; Setting the Wireless power setting for 'best performance' finally enabled my home connection.

I had the same problem. This is what I did to resolve.
got to start menu,settings,connections,then connentions again. then go to advanced, then select networks In the first box put my isp.(or create it). In the second box should be your t-zones settings.(dont edit)then hit ok twice and then exit to today screen. Give this a try, it worked for me.
The reason this is happening is because the proxy servers used by all major carriers are only available from inside thier network. Im not sure if it is because of DNS records are not provided from outside their network. Once you connect to the WiFi network, the proxy server is unreachable.
For other purposes than this, I have 2 networks setup. One with all the proxy settings for the cingulara network and one that doesn't have the proxy settings. Its easy enough to change when you just have to select a different network to connect to the "internet" with.
Can't have proxy server set up and use wifi too....
My first wizard had defective wifi card. I spent numerous hours with the tmobile support and HTC support to try and get it to work. The first thing they had me check was to disable proxy settings. Both tech supports straight out told me you can't have both. I once saw some thread where someone adjusted a lnk file or registry value so that when wifi was turned on, the proxy settings were disabled;when turned off they were re-enabled.
Hope that helps, Jess
I have a HTC Wizard running WM5. I am running a connection with proxy settings and one without. I can turn on wifi connect to IE and then turn off wifi. Re-open IE and gprs will connect and then load page. I did'nt need to use any special registry settings.
