More wi-fi problems

---

Got an AT&T Titan today.

It seems to have wi-fi problems. I've connected it to my wi-fi network but frequently the phone refuses to *re-*connect to it. It can see the wi-fi access point and shows it with full signal strength but "forgets" to reconnect. When I tap on the connection in the list in wi-fi settings it will usually connect but sometimes will put up the popup saying that it could not connect.

I do not have this issue with any other device on the network (and I have many). I suspect that this related to the issue being reported on the other thread in this forum, that the phone starts to prefer 3G over wi-fi even when wi-fi is connected. There's a similar issue with the Radar.

Anyone find a way to work around this, maybe with some magic settings on the wi-fi access point?

Edit: maybe my AP? I'm trying a different one to compare.

Exactly the same problem here.. Wifi is unstable as hell, when it's been on for some house.. You never know if and when it's gonna connect again.. HTC drivers

No problems with WiFi here. My connection is always stable even when switching to other networks.

Update: I've done a few things with my wi-fi AP and at least one of these measures seems to have helped, as I've not seen the problem since:

* Turned off 802.11b/g/n, turned on 802.11g only
* Turned off QoS
* Changed wi-fi channel to 5
* Added a second AP also set to 802.11g only (same SSID, channel 8)

According to the phone's wi-fi signal strength display I shouldn't have needed the second AP, but with it I definitely have a much stronger signal all over my house. BandWidth shows a speed bump from ~5M to around ~10M.

So maybe the Titan is very sensitive to signal strength? Or doesn't like 802.11n. Or maybe it just doesn't like the Belkin router I have.

I'll be trying this at work tomorrow to get even more data points. I use this thing on GoPhone and so non-reliable wi-fi --> the Titan is going back.

This seems to be a common bug. Mine is doing the same. It can be helped by disabling the data connection in mobile settings while you want to use the WiFi. Not a solution, more of a workaround but it bodes well for a software fix I'd guess.

I think this phone's wi-fi is working but is extremely sensitive to fringe wi-fi signal and/or channel interference.

Since I added a second AP in my house and adjusted the channels to avoid conflicts with the neighbors (using a wi-fi analyzer on a tablet), I have not seen this at home.

At work I've only seen this happen once, and it was near a doorway (where the wi-fi signal presumably is at its weakest in the building).

Mine seems to have developed this problem after installing the latest update from HTC (still on 7720). This happens even with the 3G turned off..

Hopefully it will be fixed in the next update because it is quite annoying!

hard reset makes a difference

so i spent a bit of time with htc support. they recommended hard resetting as others had warned me. in the end i got so fed up with it i tried it and actually the phone is much better on wifi right now. i totally cleared out zune too and reset everything i could think of. one thing i had on before was wireless sync. decided not to bother this time. no idea if it's the culprit but are you guys having problems using wireless sync by any chance?

I have also been experiencing the same issue with the AT&T titan. My old Focus works great. I know that HTC had some problems with the using spoofed MAC addresses and maybe the fix has something to do with it. HTC is a great company, but it seems to take them a few versions to get their code clean.

I manually pushed 7440 to my phone and I am not sure if it is related, but I have not experienced the WIFI issue since. The patch does not mention anything about WIFI and since it is likely a driver issue, probably a wild goose chase, but...

This thread has the instruction in case you want to try:

I take it back. Just got home and the problem still exists.
