I just purchased the Tilt and love the features and possibilities, however I may be forced to return it if I cannot solve this problem.
I can connect the Tilt to my home WiFi network (Open/WEP) without any problems, and I can connect to several other APs (Open/Encrypted and No-Encrypt) without any problems.
In my office (where it'll be used the most) we use Cisco's lightweight access points with the WCS controller system. This system is configured with Open authentication and no encryption, and has a captive portal that you must login to in order to gain access to the network.
When I connect to this network, I stay connected for about 30-45 seconds (I can ping the Tilt from my wireless laptop for about that long), and then the Tilt stops responding on the network. The WiFi status says that it is reassociating with the network, but it never does. I can manually tell it to connect to the network, but that fails, too. While this is occurring, I can see all of the SSIDs (including ones not on the Cisco controller) that are available in our office, but cannot connect to any of those, either.
After a soft reset, I can connect to any of the other SSIDs with no problem until I try to connect to any of the SSIDs that are on the Cisco controller. After trying that, it repeats the same pattern and I must reset the Tilt before it will connect to any other access point.
I've actually done some wireless captures and cannot see any problems with the communication between the Cisco APs and the Tilt. It's just that after this "malfunction", the Tilt will successfully perform the normal 802.11 open-mode authentication, but will never proceed to the association phase.
I've talked to AT&T and HTC, and they told me my phone may be defective and to try a new phone. I've done that now, but it is still doing the same thing.
Has anyone had any similar experience?
Thanks!
This was a similar issue with my phone[Similar by reassociating with network, and soft reset], except it was on a campus[uses cisco] and not office! Basically i just had to register my kaiser's mac address with the school, and everything worked perfectly. Hopefully this helps!
That's an interesting observation. A campus network would be similar to my (large) office network.
Before you registered your MAC with the school, were you able to browse to anything?
I ask because our network doesn't require MAC addr's to be registered. It allows anyone onto the network as a "guest" and then you have to browse to a web page that lets you login to get Internet access.
But, the fact that you had to do a soft reset to get it working again is quite interesting, and points to a bug with WM6 or the device.
The Cisco WCS has some protection against DoS/etc. Maybe the tilt is doing something that's causing the WCS controller to think your device is a bad-guy and it places you on a blacklist. I think by default the WCS has a blacklist timer of about 5 mins... can't remember now. Could be what's happening though if after a reset you can't see the WCS SSID anymore.
That's a great point, too. We don't have any of the IDS/IPS functions that you're referring to turned on, but there's always those hidden features
We ran a quick test and watched the debug output of the WCS and didn't see any messages to indicate foul play.
It turns out that this problem was specific to Cisco's WLAN implementation. Cisco has a set of wireless extensions called CCX that are implemented on wireless devices (clients) to aid the infrastructure in managing the radio environment, location management, roaming, etc.
Apparently the WiFi chipset and/or drivers on the Tilt do not implement CCX (as 90% of other radios and drivers do), so when the WLAN sent a broadcast out asking for radio management reports, the Tilt's WiFi stack would just freak out.
We were able to work around this by disabling the CCX Location Measurement function in our Cisco 4400 series WLAN controller.
It would be nice to see an update from AT&T and HTC to fix this problem.
same thing happened to me.. same cisco wlse and same pda.. i also have to disable CCX. but it is quite useful feature of WLSE. i hope htc can fix it.

Anyone know if a new driver is part of WM 6.1? I am holding out for the official AT&T version but was just wondering since I have this problem with the wifi at school.
I’m here on the coast at Keesler Air Force base. There is no internet to speak of and I do not want to spend roughly $1,400 to obtain it through a Cell provider for my laptop. I setup the Internet Sharing on my TILT and it works somewhat. Well, I lied. It stays “connected” however the damn thing peers off and the laptop continuously loses connectivity.
I only use Skype and sometimes webmail with the Internet Sharing and it cannot handle it. Every minute, sometimes up to six minutes, Skype videocalls and standard webcalls are dropped and I test the internet connection to see that it’s timing out for another minute or so and then it magically reappears.
I closed all applications and the antivirus crap to ensure that there was no extra throughput bandwidth. Anyway, I’m about to lose my damn mind here because I cannot stay in contact with my fiancée who’s on the other side of the globe right now.
According to the phone I’m only getting the Edge network and that makes sense as there are not 3G towers nearby. The signal continually shifts from two bars to four bars. I have used the Kraiser Tweak to enable HDSPA but that service is not being picked up.
Any ideas as to how I can keep the connectivity from dropping between the cellphone and the laptop? I assume that’s the issue as the phone stays “Status: connected” within the Internet Sharing application.
If it matters, I can only use the "Media Net" option under Network Connections. Media Net utilizes the wap.cingular access point.
I have tried to use the "ATT ISP GPRS" option but it continually loops through attempts to connect to the internet. Eventually it gives up without any success. The ATT ISP GPRS uses the isp.cingular access point.
Please any assistance would be most appreciated. This United States Airman is about to lose is frigging mind over the fact that he can’t communicate with anyone any longer. Ugh!!!
Thanks to any thoughts and advice to better my situation...
Oh and for the record, if it isn't understood being a Tilt, my provider is ATT.
HSDPA will not work without 3G service. MEdia Net is the best way to tether, I use it all the time. Make sure the proxy option is unchecked, or you will get very poor speeds and high latency.
What do you mean by HSDPA? Also, I tried with MEDIANET but I continually lost connectivity. However, ATT ISP GPRS seems just as bad if not worse. Any thoughts on something I can do to boost connectivity? I don't know about the proxy but where I looked one is NOT enabled.
I enabled IP Compression and Software Compression for ATT ISP GPRS and it hasn't seem to have any affect...
Thanks a lot.

You mentioned HSDPA, so that's why I said it. As for ATT ISP GPRS, you do not want to use that unless you have a modem tethering option on your AT&T account. If you go under MEdia Net settings, and then check the Proxy tab, make sure the proxy option is unchecked.
Allrighty, I've confirmed that the Proxy is not enabled. The only thing on the Proxy option section that is enabled is the first option where it says this network connects to the internet.
Any ideas on stabilizing internet on a 2 - 3 bar Edge network? If I do more than one task (more than one website OR a website and Skype) the internet gets lost quite easily...
Thanks a lot man.
Wow when I was over that way I dont recall have any issues with ATT and internet. When I access the net while tethered I use the ATT program that connects via laptop... Its not the internet sharing program.... Its called ATT Communication Manager... It may read as being tethered so if you dont have tethering on your plan then I dont know if id use it. If you have tethering it works great for me. Heres a link for the download...

You might want to try flashing another rom and radio. I remember I had an issue similar to this with my hermes from ATT. Swapping to another radio can definitely boost your signal quality. If your signal drops too low even for a second, it can cause major latency issues on the edge network( which WILL cause skype to dop a call ) . I recommend trying a ROM that already has a radio packaged in with it to save you the trouble of having to match a radio to a rom. Also look for one that has the network configuration cab built in so it can automatically set up your Connection settings for you.
Hope this helps
Allrighty... I don't have much time to research ROMS or RADIOS unfortunately. Any suggestions on where to find them, or what I might use? I'd almost prefer just to change RADIOS so long as I can find the original RADIO to replace any changes back to what I was using...
Currently, I have:
ROM 1.62.502.0
RADIO 1.27.14.09
Any help to further this US Airman along would be appreciated.
Thanks.
Hello to all diamond people,
We all know, there is huge issue with this great phone about Wi-Fi connections. While Wi-Fi is one of the reasons people choosed touch diamond, what is their disapointment when they find out wi-fi doesn't work as it should.
I am talking about problem I am experiencing by myself - I am unable to connect to my home WPA secured and encrypted network. If I turn the security off on my router and wireless network becomes open, there is no problem at all.
But who wants unsecured, open wireless network at home, so all the neighbours can download whatever they want through your network?
Nobody.
During my research throughout forums I have come accross many people, experiencing same problem, but was not able to find the solution to the problem, or what is causing it.
My aim is to gather as many information as possible to help to fix this problem, so everyone could use wi-fi on their own home WPA secured wireless network.
Any ideas?
What is your ROM and radio versions? I've no problem connecting to my WPA enabled network. Which WPA option did you choose? It must match the same WPA option on your router. There are WPA, WPA-PSK, WPA2, and WPA2-PSK, then there are also TKIP and AES to choose from. Try setting both Diamond and router to use WPA-PSK (TKIP) first, this should have the highest compatibility with other WPA supported devices on your network. And make sure you use a strong passphrase, you can use a WPA key generator.
Hey,
both router and HTC are set to WPA -PSK under TKIP encryption. I use my own network key.
The thing is, in wireless lan manager i can see htc does connect, but only for about a second, then it starts reconnecting all over again.
Sometimes it does connect and works for few minutes and sometimes it does connect to router, but not to the internet. It drives me absolutely mad.
I tried Advanced Config -> Network -> WPA authentication - enabled/disabled, but still experiencing problems.
I have heard there used to be issues with ROMs provided by the network operators, but that is not my case.
ROM: DIB Diamond v 1.33
RADIO: 1.00.25.05
WPA secured
Hey,
If You want to use WPA secured wireless networks with Diamond go to Settings-Wireless LAN-Power Mode and there set Power Save Mode to Best Performance. It works
Sorry for my English...

I guess it's probably not your ROM, since the DIB Diamond v1.33 is based on the newer 2.03 ROM. I was wondering, do other devices on your network have the same issue or it's only the Diamond? Connection dropping can be many reasons, and one of them is the router itself.

I don't have any problem even in Power Save mode.
Somewhere I have come accross the information some routers (particullary Belkins) do have problem with windows mobile devices.
Today I wrote to Belkin Support, thay should reply in 72 hours mad, however we may know more.
Since I am using unsecured wireless network now, at least I have activated the MAC addresses lock - only allowed MAC addresses can connect to router now. What do you think, how secure is that? There is no encryption now, could someone see the sommunication between me and the router?
Which Belkin router are you using? Check if there is a firmware update, you may want to try that.
MAC address filtering should be ok for now, it can stop the majority of people who try to use your network, it will take someone with a bit more networking knowledge to gain access to your network, but most people don't have that knowledge.
Yes, people can capture any unencrypted packets and read them. But if you're connecting to a secure website through HTTPS or any other secure protocols, the packets are still unreadable. For example, in the browser, if it's written https instead of http on the address bar, those sites are secure. Most regular websites are not secure though.
I was having a similar problem on my Touch Pro a while back. My router is also set to WPA-PSK/TKIP. Although you said you tried it, the solution for me was indeed to go into Advanced Config > Network > WPA Authentication > Disabled. I then removed all previous wifi settings and then added them again, and it connected without a problem.
It could be that there's something else preventing your connection, but from what I can tell you should at least have that setting disabled.

its pretty secure, as you cant guess the password, you would have to get in and add your device to the list (which you would need the username and password for)
Does the N1 have 5GHz wifi like the Samsung?
My home LAN is 5GHz only, so I don't disturb the neighbors with my video streaming.
No, 2.4 only...
Ugh.
OK so I turned on the router's 2.4GHz, but with broadcast SSID off. My N1 wouldn't even try to connect. So I turned on router SSID and it connects AES.
I do -not- want SSID broadcast on, as Windows machines' lazy active scan will find me. Sure they'll never get in, but I do not want broadcast on.
Has anyone succeeded in connecting with it off?
When I am connected wifi and open a website on the phone, does it go over wifi preferred over 3G?
I want to share the SD card with a machine on the LAN. What's the best way to do this? FTP? Reverse SSH tunnel? Is there a sshfs for Android? EDIT: NM on this one.
Yes, I remember connecting to a WiFi with SSID off, when I had Nexus.
It is pointless to keep SSID Broadcasting off. It is super easy to find your SSID anyway, and it causes all sorts of additional problems (like the one you are seeing above). Just keep the network secure and it makes life a lot easier.

Ok, but sure passive scanners like Kismet will still see me, however 90% of scans are done with an active scanner like Winduhs. Of course I'm using WPA2-AES, but I want to take every measure possible.
Now I find that whenever I have the phone connected to wifi, I lose -all- internet access. Just times out. 3G is still on and wifi is showing connected, but I can't get to websites. As soon as I turn off Wifi I can access the internet again through 3G.
With wifi I -can- access the wireless router's setup webpage from my phone, which tells me I am working through wifi, and I can remotely mount the phone filesystem on a LAN machine using sshfs, but I can not reach anything outside. Any idea why?
Does anyone know whether, when it's working right, it uses the wifi connection in preference over 3G?
The WiFi is ALWAYS preferred to 3G, which means - when you're connected to WiFi, all the internet traffic is routed through WiFi.
I don't understand then, why all data traffic stops to the outside when wifi is connected. The rest of my LAN gets outside fine, just not the phone.
If you can see LAN computers and exchange data with them - it's not the phone that's making problems. See if you have any restrictions in your router.
Oh FFS, my fault...
I set my IP statically for my LAN, and through some alert troubleshooting I found I can ping IPs outside but not DNs. I'd mis-set the DNS server in wifi settings. Now it works great!
I can now use sshdroid to mount my phone's filesystem on my LAN securely. Now, if I could only get it to wifi associate with beacon off...
It would also be nice to mount a filesystem on my LAN to the phone, although I consider the phone unsecure and question the wisdom of that, even with DroidWall running.
There is a market app that lets you connect to a hidden ssid

Cool, but Market is FCing on me. I did a complete reinstall of the newest MIUI.us, and now Market's FCing again. So can't install any Market apps.
As someone else said, turning SSID off is pointless. It's like taking the numbers off the outside of your house and thinking people driving by won't see your house sitting there.
Apparently you didn't understand what I said here:

If nothing else, please just respect my decision in this regard, or give valid proof that active scanners are not the preponderance.
Whenever I'm connected to my vpn (surfshark), my s20fe registers my wifi connection as a metered one, which never happened on my previous two phones. I've set the particular wifi to be treated as unmetered through advanced settings, but it hasn't changed a thing, and various apps that I've set to require a wifi connection for backups/checks aren't working as a result. Is there a way to remedy this?
