For the most part my wifi works pretty good, but I have problems with my touchpad wifi at work. The wifi connects for a few moments then simply loses connectivity. The setup at work is a system of enterprise access points all using the same ssid, and for whatever reason it throws the touchpad (and some other android devices) for a loop. My android phone used to have issues too, but it was fixed with a custom rom, and webos connects fine also.

I have tried almost every rom with mixed results. The "Bricked"rom v4 gave the best experience. CM9 A6 was ok.. Next I tried classic nerd buttah 0.1.0 v1 and v2. I found it wasn't really any better than other roms out there, and had some pretty annoying glitches. I read though all of the classic nerd posts looking for answers, I found their thread to be hostile, so I didn't bother posting any questions. I promptly uninstalled, and moved on to CherryKang with the hopes that the wifi driver fix would work out. It didn't seem to do anything, but I have to say that CherryKang runs pretty good, hasn't given me any problems, and I like the 132 dpi. Every install was preceded with full wipe.

So I started tinkering with the build.prop and wpa_supplicant.conf

My hope is that something in there can be tweaked and solve my issue.

After doing some research I found a few settings that have helped other people:

-Changing hostname to a shorter hostname. The default touchpad hostname = android-78abb09201c4bca8. Edited the build.prop and added net.hostname=touchpad

found here: http://ergh.org/cmtp/-

*didn't work for me but may work for you

-Setting scan_ssid=1 in wpa_supplicant.conf

Oddly made the disconnects less frequent. Still testing

-Disabling WMM support. WMM causes havoc with some routers and devices, shutting it off sometimes clears things up.

*haven't tried it yet but I will post something when I try it tomorrow.

Other than that, I'm not sure what to try next. Any ideas?
[TouchPad Development] bobtidey:
Your experience I think is very similar to mine. I could get home wifi access OK by adjusting router, but work access was a complete nightmare with none of the ROMs being perfect. Most were very difficult to connect and would disconnect after a few minutes making them unusable.

I find CherryKang is much better and typically lasts about 3 hours for me. I did also try all the wpa_supplicant tricks like you say, short hostnames etc but I can't get it perfect at the moment. What is interesting is that if I turn wifi off and on to get it to reconnect then it either obtains ip straightaway or there is a delay of about 30 secs and then just says saved and isn't connected and won't recover from that. It is about 50/50 which happens and I suspect something similar is happening with a rescan to cause the drop out after it has been functioning. The work SSID is also not published and I wonder whether that can have an effect.

I tried out WebOS at work again to get a benchmark, and got 8 hours with no drop outs so the hardware and access point can function OK.

I am a little puzzled by the nature of the wifi fix in Cherry Kang so plan to post a message in there and I notice some other wifi drivers for a similar device seem to be surfacing. So I'm optimistic that this issue will be finally sorted out soon.
[TouchPad Development] Nizda1:
Bobtidey,

I also have done some in depth research regarding the wifi issues and the patches some are compiling into their kernel or as the other post in the CherryKang thread suggested manually inserting and removing the new/old modules. I definitely am noticing an increase in performance when I tried the rom, wifi was stable but for me I just got lucky and have not really had problems besides the random disconnects and what I thought was hanging turning it on. Anyway let me quote from the commit of which both these fixes originate from "Patch Set 1: I would prefer that you didn't submit this This needs stress test before it can be committed (dalingrin)." "Patch Set 1: I'm wondering if you get any firmware crashes using the new ath6kl module (check dmesg - it was the main reason why activating Wi-Fi sometimes takes very long). That's the main reason that I withheld this patch for now." So that prompted me to be a little skeptical on using this as obviously I would consider dalingrin's advice over all. There's some more to it than this as there is also a timing issue that causes crashing :

"This is not quite ready. It is the most promising driver for us going forward. However, none of the android specific functions are implemented yet. There also a crash related to timing issues though I think I can fix that. I will upload another patch set when I get a chance."

Anyway just thought I'd chime in on the subject especially after the last comment which in my opinion is rather unsettling

Links/sources from quotes and for a nice look at the material.

Classicnerd Butta v2 vs v2.1

Add'l infoI have been running the succession of Classicnerd team builds including the predecessor Xron series. I had no problem in either WebOS or in any build until Classicnerd-Butta-0.1.0-v2. Then I had several instances of connection failure after waking.

I also noticed that the signal strength was shown as dismal even right next to the router. I'm thinking that some of the problem may be the radio not waking up when the tablet does. I was able to connect by tapping the SSID listing on the TP. Then the signal strength returned to normal.

I updated to v2.1-Odex yesterday and haven't experienced any more connection failures. :cool:

All of my flashes have been done with factory reset and wiping everything on clockworkmod, reinstalling Gapps and reinstalling apps. I have not restored any backups or backup data.

Update: I have now experienced a couple of instances where the wi-fi is not connected and doesn't automatically reconnect after the TP has been sleeping. Simply turning off and turning on the wi-fi has fixed it.
[TouchPad Development] mike-y:
Just an update on the issue I was having with my 5g network. I changed the "wireless networking mode" on my router from "N only" to "mixed" and am now able to connect.
[TouchPad Development] bobtidey:
I had looked at those before, but I think they may have changed a little now and clarified things. If my current understanding is correct then Cherry Kang has the new board file referenced in the 12342 and gets some wifi benefits but this is a temporary measure. 12341 then refers to fundamentally replacing the drivers when more work has been done on them, hopefully leading to even better long term wifi support.
[TouchPad Development] krook6023:
WiFi has been beat to death in almost every thread in the development section, I encourage this thread and hope it can decrease the the clutter in the ROM threads.

I have said this many times, and this is very true in most instances...however in this case I feel differently.

[TouchPad Development] bobtidey:
This morning at work my wifi was dropping out more frequently than recently even using Cherry Kang build; it was lasting about 15-30 minutes.

It seems to be correlated with the probability of it connecting properly when wifi is toggled off and on. When it works it immediately says getting IP address. When it fails it delays and then just says saved. This morning this was happening 50% of the time and I had to toggle it off and on again a few times to get it to connect.

I suspect it is also something to do with re-activating the device from screen off even though I have wifi set to the default of never sleep.

So in the afternoon I left it on WiFi Analyser app with the setting to prevent the screen turning off. It stayed connected for 5 straight hours leading more credence to a theory that is somehow a re-connection on screen waking up that could be part of the issue.
[TouchPad Development] dahauss:
Has there Ben any fix for the wifi issue? I'm almost ready to ditch Android on the tp and get a real tablet.
[TouchPad Development] jsgraphicart:
So I am running CM9 Alpha 2. I notice that sometimes, when Im trying to load a web page, it will act like I've lost connection and stop loading half way through. I have to keep hitting refresh until the web page decides it wants to load. Also, with youtube, I sometimes cant get through a whole video without it stopping and not load the rest of the video. Ironically, Netflix works pretty well. The wifi icon at the bottom stays "lit", it just seems like it momentarily loses connection. Are these issues related to the wifi? Should I try the drivers posted on the last page?
[TouchPad Development] rydeordie99:
Yes definitely. But I highly recommend that you first wipe and upgrade to the latest cm9 nightly as there have been a lot of improvements since alpha 2
[TouchPad Development] nevertells2:
Which rom date, official or unofficial?

---------- Post added at 09:18 PM ---------- Previous post was at 09:15 PM ----------

I have noticed this lately using the stock browser and Firefox as well as on my desktop PC. So not sure it CM9 that is the issue.

ath6kl compatibility

I notice that in the latest O.A.T rom, which previously included the ath6kl drivers, there are now two variants as he found the latest kernel update is not compatible with the drivers at the moment. One version has old kernel and updated drivers and the other has new kernel but not the driver update.

Reason for posting that here is that it probably also means that it is not a good idea to flash the driver update zip on top of very recent CM9 roms until that gets resolved.
[TouchPad Development] LikeaG2root:
I am currently on cm9 latest nightly.I was previously having issues staying connected using cm9 and aokp builds. It was bad and so I went to my router settings. I have a Linksys router with both wireless G and N. I disabled the N signal and set my G signal to channel 1. Wi-Fi is working better than ever and have not had any disconnects since the change. So apparently the N signal interferes with the hptouchpad's reception. Hope this helps someone

routers

i am not having any problems with cisco wireless router am on n setting, initially i had a problem on the touchpad along with my pc but it was due to time change correction on the touchpad,do all hp touchpads have the same recievers or do they differ ,if they are same why are we having different problems on the same device or are they defective,i have other android devices and none of them have behaved like this.i think when we have the source kernel from hp it will solve all the issues.
[TouchPad Development] Moshe5368:
While it would be nice if the source code release solved all the android issues for the Touchpad, do not expect this to be the case. HP is releasing the webos source code only. The drivers for the broadcom wifi are, and will continue to be, closed source. Most wifi issues currently have work arounds and they vary as much as the software versions available for the touchpad. Some android releases for the touchpad have more stable wifi than others but there are so many variables involved that I expect to see wifi issues continue for quite some time. I currently have 3 touchpads and, at times, have had to use various workarounds to get wifi reception to be stable.

The fact that we have an android install is a blessing so the wifi fixes are a small price to pay. HP developed a great device and we have the ability to dual boot android. I am content with that.

kernel mode change

Linus Torvalds has said that the kernel from 3 onwards are going to incorporate android support in it ,i hope it will help everyone on xda forum with regards to android device support so that the wifi issue is gone currently on latest cm9 tenderloin build with no wifi issue with wifi mods 1.5.

i think the cm9 builds are still using 2.6 kernels i hope when they have stable 3.0 kernels thay can make a stable switch with great support for wifi.
[TouchPad Development] MikeCriggs:
Dalingrin is working on a Linux 3 kernel atm. Hopefully we'll see it soon, but it might be until July when HP releases everything.
[TouchPad Development] mkosem:
I've had my TP since February, most of the time running CM9, and haven't had any wireless issues with it at all. My home wifi network is hosted by DD-WRT on a Linksys WRT610n. The 2.4Ghz and 5Ghz networks are both set to N only, channel auto selection, and are both mac filtered. I installed AOKP last night and wifi was stable on it as well. I generally have the TP on the 5Ghz network, but haven't seen any issues with it on 2.4Ghz either.

[TouchPad Development] nevertells2:
You seem to be one of the lucky ones. It's a mix of hardware(routers) and software(wifi drivers) that affect what kind of wifi issues a person has and which work around helps. Hopefully some day the devs will figure out just the right kind of magic and Android wifi on the TouchPad will work just as well as is does on the WebOS side.

2.9 driver on Touchpad eyeballer 050112

I downloaded the 2.9 driver and flashed it to my touchpad

running Eyeballer 05/01/2012 ROM.

My wifi has been

perfect

so far(24 hours so far).

I have yet to connect on WPA2 yet, but on WEP and open routers it's been perfect.

Thank you for the brilliant site.

I found it with a bit more reading.. seems to be working with AOKP M5 (at least I can boot up fine) :D

will see if it fixes my wifi issues as it did with M4
[TouchPad Development] -Maverick-:
What are the odds, I have the same setup as you and have no problems either. The only difference is I turned off the 2.5 GHZ band. Public WiFi is hit and miss though.
[TouchPad Development] robrob777:
Running AOKP M5,

I never had disconnect issues, but now in OOKP sometimes my wifi reconnect sautomatically after sleep (policy is to never keep wifi while sleep) wich is good.

BTW went from CM7 to AOKP w/o wiping, not recommended but it works.
[TouchPad Development] ryuken11221:
My only issue with wifi is that if I step like 10 feet away it goes in and out but my phone and PS vista still shows up full bars I'm running the latest nightly build with the latest version of gapps to I just got my touch pad yesterday and this seems to be the only bug I have got tin besides not being able to fully use Google voice, camera, and mic but other than that everything runs very smooth

[TouchPad Development] Flashmaniac:
Since two days I have massive wifi problems.

Wifi simply not connects to my network anymore.

So I tried wiping data etc wifi then works but after a reboot it does not connect again. I don't know what can cause this problem but on web os wifi always works fine so I guess it's not hardware related.

Removing the network and turning off/on wifi then reselecting the network helps until I reboot...

did someone have that kind of problem too?

running latest official cm9 nightly and latest gapps.

Toggle on Airplane Mode

Toggle off Airplane Mode

Turn on wifi

Wifi bars decrease a lot for me when using ath6kl but the only way to get the touch pad to attempt to connect is by ath6kl.
[TouchPad Development] ryuken11221:
Oh OK well its great that it works for you

Using the ath6kl drivers seems to half my wifi bars but yet it connects???

It'd be nice if it kept the strong signal from the normal wifi driver.

Possible reason because I don't have that issue. Wifi Sleep Policy is set to never too.

After a full day of use, haven't got any problems with Wifi (hurray!).

I did not notice any changes/improvement on battery life though. I still think battery decreases pretty fast on the TouchPad. For comparison, my wife uses her iPad couple hours every day (as I do with the TP) and she has to charge it every 4-5 day, I however as to plug it in every day or two...

Hopefully this will improve with new roms. Battery life is definitely better on WebOS than ICS for now.

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?
