Hey guys,When I first got my A81E I flashed it with firmware 0809 (custom rom.) With that, the wi-fi would be very iffy. It would either:1. Work for a good amount of timeor2. Connect, work for less than a minute (not sure of the exact time anymore) and then fail to actually transfer data. It would still say it is connected up top, but no application could access the 'net. I would come back later and it would be disconnected.Now with 0823, I get #2 all the time. Only except it definitely does not transfer data for longer than 7 seconds or so. It's difficult for me to test what happens after I leave and come back, but it appears to be disconnected and opening up a web browser and entering a URL does not make it connect (I reconnected by going thru settings and turning wi-fi off then on.)My wireless router is a Buffalo WZR-HP-G300NH (high power 802.11n 40mhz) running the latest firmware 1.74 (buffalo's proprietary linux.)In a few days I will be able to test it out with another router, a Buffalo WZR-HP-GN (high power 802.11n single-band) running the august release of DD-WRT.If anyone has any advice, I'd love to hear it.EDIT: Incorrectly stated that my router was dual-band. It is actually 40mhz wide rather than the normal 20 mhz wide, although I could put it back down to 20 mhz wide. EG, it uses something like channels 1+5 rather than just 1.

Every time you flash, your MAC address changes, not sure if that's your issue with your router

 

[mikedep333]

kjhadfield, I used the wrong terminology. My wireless router isn't dual-band, It is actually 40mhz wide on ~2.4ghz rather than the normal 20 mhz wide, although I could put it back down to 20 mhz wide. EG, it uses something like channels 1+5 rather than just 1.I think I will change it to 20 mhz wide in the morning when the rest of my (engineering) fraternity brothers are mostly asleep or at class.kmmkx2, that's very useful to know, but I secure my network with WPA2/AES. There is no mac filtering enabled. My router may give it a different ip address now that it is on a new mac address, but it obviously is getting an IP address because it is able to communicate for a short period of time.

 

[eviltuna]

The 40mhz is your problem. You gotta run it in 20mhz.

 

[mikedep333]

eviltuna, the 40 mhz is an option. Devices are supposed to fall back to 20 mhz if they don't support it.Anyway, I tried setting my router back to 20 mhz and yet it still didn't work.I went to the other access point, a Buffalo WHR-HP-GN (high power 20 mhz wide 802.11n) running the august release of DD-WRT and it seems to work great (fast web browsing) but I cannot login to google when I go to startup GMail or the Android Market. It says it cannot establish a reliable data connection.Any advice on this? I'll start another thread if I have to.

Mine doesn't connect if there are more than 1 AP active nearby....

[mikedep333]

Port blocking?

There's no outgoing port blocking on my router. Buy maybe it's the web proxy. I'll try disabling that.EDIT: Disabling my transparent squid web proxy didn't work (and I did change the firewall rule back to allowing HTTP traffic directly through.)

That sounds like my situation.

i have also run through all of the avaliable roms, i can't not keep wifi connected. in logcat, you can see it connects, gets the ip and DNS, then will reconnect about 30 seconds later. At this point on fresh install of mns ROM, can't even connect to wifi the first time. Router is open and has been rebooted several times.We need the source so we can fix it.

Are there any other ways to view logs for the market or for wi-fi/networking?

 

[fbelleri]

It 's just an attempt.After I tried all the logical things, I tried those to be desperateI changed the transmission channel to number 11 in the AP and it worked.Maybe it can work for others.
