The ath6kl driver has been merged today into the official CM9 build. So it should be at latest in tomorrows nightlies :)

I don't know which version of the driver it's though :(

The ath6kl mods made it into the May 22 nightly build. I reflashed this morning with it because of that. Unfortunately it didn't help with the enterprise WPA2 setup we have where I work. I was really hoping it would. The firmware crashes.

I'll try to get a dump posted somewhere for further review.

---------- Post added at 11:07 AM ---------- Previous post was at 10:35 AM ----------

After the new nightly, I'm seeing the following when I connect to my employer's enterprise Wifi. (WPA2 Enterprise, PEAP Authentication, MSCHAPv2)

We have other devices which work great on the WiFi, so I can't necessarily fault it... But it works great on my other WPA2 PSK Wifi networks (so far).

How is the new driver? Does it fix any of the sleep issues? Also, I noticed that my wifi on cm9 gets less range than when I boot into webos. I can go far enough away where cm9 will not find my network and then I'll boot into webos and it generally pulls up the network with a near full signal. Do the new drivers fix this issue?

My battery life has definitely improved, wifi signal is a lot stronger but still not quite as good as webos but that's to be expected

As for me it solved the wifi sleep issues, that's for sure. Signal seems to be stronger as well, even tho it sometimes just stop loading pages. If it comes to battery life there are still some issues. I often leave my touchpad unused for long time. With build from 30 may and wifi driver around that date device dies after 48-50h when not being used. There's almost no activity on battery stat page so can't say what's using so much. On alpha 2.1/3 it used to survive 6 days when left unsed, so there's still a lot of work to do.

I have two 32gb TP's, one with the 0527 official nightly and the other has 0517. The 0527 nightly has one of the older wifi drivers that JC Sullins provided and I can set sleep policy to turn off wifi when the TP is put to sleep. I have been using Battery Monitor Widget to watch current usage and have noticed that I get reading similar to my other TP that has sleep policy set to never. I can definitely tell on the 0527 TP that current usage is much improved when asleep. The 0517 TP I turn off wifi from settings and use around 30mA, do not get alerts, email or anything that requires wifi. When I wake it up and turn on wifi, it takes around 25 seconds for wifi to reconnect to my AP. The 0527 TP uses around the same mA's as the other, but I get alerts, email and the like while it is asleep. I see occasional spikes in mA's used which I figure is when the wifi wakes up to receive email, then it goes back to around 30mA. Also when I wake the TP up, wifi is up and running after a couple of seconds.

\Does anybody else get problems with Youtube using the latest wifi drivers? At a certain point Youtube videos just stop buffering and I have to toggle the "HQ" setting for it to continue.
Actually the problem is not just with Youtube - its with any operation that needs to maintain a network connection for a certain length of time. I also get web pages that don't load all the pictures, Facebook app doesn't load all the pictures, dowloads stopping etc.
With the drivers prior to 0522 I never used to get these kinds of problems. :-(
BTW, my wifi router is set to channel one, 2.4Ghz etc. I have two wifi access points and I get the same symptoms with both. I also get the same thing when I connect to my phone using wifi tethering.

My Touchpad just continues to refuse to connect to any of the Wi-Fi networks at my university when using an Android ROM :(

Works fine at home though...

Oh well, looks like I'll have to stick to using WebOS when I'm at school.

You say the latest wifi drivers. What version of the drivers are you using? It most likely depends on the date of the nightly you are using.

You need to explain more. What Android rom? Are you using CM7, CM9, ClassicNerd, AOKP, etc. If you are using CM9, what is the date of the nightly you are using?

Sorry about that.

Tried AOKP TL4 and the latest CM9 Nightly + CN

Anytime I tap on the wireless networks at my university, the connection configuration window does not appear after the first time. IP won't configure. Restart doesn't change any factors.

At home, it works normally like it would on any other android device.

Thought I read a few months back that HP would be releasing something that would fix wifi for good in July. Am I wrong or will that happen? When should I set my calendar to come back and check?

I have never had a wifi issue that I know of. I used to run scott's MIUI, then I switched to CM 9 alpha 2 when it was released. Is there anything I can do to contribute?

If you install the July 7th nightly, you will have the latest wifi drivers and they work quite well.

You should stick with the latest ath6kl:

There are no issues since it has been merged into the nightlies almost 2 months ago.

    This thread is intended to be a gathering point for all wifi issues on Android Touchpad ROMs.

    Having a separate specific issue thread for this will serve several purposes.

    • Avoid wifi issues getting lost in the more general Touchpad ROM threads.
    • Allow issues common to wifi operation on all the different ROMs to be concentrated in one thread.
    • Reduce annoyance to those who are currently enjoying good wifi operation and who see repetition in the issues being aired.
    • Make it easier to report tests and experience on different set ups and as new drivers / ROM integrations appear.
    • Make it easier for users with questions to see if it has been asked before.

    Background
    Wifi operation on Android Touchpads currently is a hit and miss affair. Some users report flawless operation regardless of access point. Others can get stable operation with careful set up and / or choice of access point but problematic operation on access points over which they have no control. Others still fail to get conditions right for any form of stable operation.
    This is in comparison with WebOS based operation where the problems seem to be much fewer. Probably most of the explanation for this difference is the current lack of suitable drivers integrated into the ROM environment. Hopefully this will be fixed at some point and there are some encouraging signs already that improvements are possible.

    Factors affecting operation
    There are several factors which could potentially affect the wifi performance with Android Touchpads including the type of Access point, the set up of the Access point, the local signal strength and interference conditions, variations in Touchpad hardware build, and how the ROM software has been installed and set up. A key factor on top of all these is the wifi drivers used and how they are integrated.

    General advice
    Until the fundamental performance is improved the end user of the Touchpad can do some things to help get better performance particularly if they have control over the Access point. Typically this will be in the home situation. Possibilities for adjusting setting for work or public access points tend to be small or non-existent.

    Note that not all suggestions work for everybody affected so you have to be prepared to experiment a little to see what may work for you.

    The primary suggestions I offer that worked for me in my home situation is to lower the channel setting on the router to Channel 1 even though for me that was worse from a local interference point of view. Other suggestions include avoiding dual band operation and experimenting with security settings (like using WPA instead of WPA2).

    Posting
    Please post to this thread if
    • You want to ask Android Touchpad wifi specific questions including problems you are encountering
    • You can answer Android Touchpad wifi specific questions posted here
    • You have reports on specific problems that may help resolve wifi issues
    • You have suggestions on how to improve operation in the short term with existing drivers
    • You have reports on new driver operation either better or worse.

    Please also include the ROM and version used in any specific reports. Although wifi issues have been present on 2.3( e.g CM7) and 4.0 (ICS) the focus for development is now firmly on ICS and that is where improvements are likely to be made.

    It is unhelpful at this stage just to post here that you do not have any wifi problems unless you have some specific advice on how that can be generally applied. We already know there are many who enjoy good wifi performance.

    Currently I am using CherryKANG 0.2a which does have some experimental new drivers in and for me gives much better performance.

    So no fix yet for wifi :(

    Until today I could not connect to my home network without forgetting it and reconnecting, and my uni's network has been almost completely unusuable (on CM9, whereas webOS has been great).

    Attempts to manually change locale/region in various ways have all failed.

    adding "ap_scan=2" to data/misc/wifi/wpa_supplicant.conf fixed the problem with my home router. Hoping it will work at uni as well.

    If you have wifi trouble, if nothing else can help, and if you're bored, maybe you can set ap_scan mode to 2. This mode seems to be appreciated by some of the more frustrating/crappy drivers out there. If it works, let us know! Maybe try ap_scan=1! Good luck :)

    Clearing /data/misc/wifi and rebooting makes my touchpad connect to the router without any hesitation, I guess it is similar to forgetting and rebooting(but haven't tried that)
