Do I understand you correctly, you flashed Neejay's zip into the CherryKang rom?

If that is what you did, be aware that CherryKang already has a fixed wifi module in it.

---------- Post added at 09:28 PM ---------- Previous post was at 09:24 PM ----------

Several weeks ago, Dalingrin pretty much panned this build.prop modification. Sorry I don't have the link, but he said that using it is mostly a waste of time.

---------- Post added at 09:33 PM ---------- Previous post was at 09:28 PM ----------

Launch the terminal app.

Type su and tap enter. If asked for super user permission, allow it.

Now type the following: rm -rf /data/misc && reboot

For clarity thats: rm(space)-rf(space)/data/misc/wifi(space)&&(space)reboot

and tap enter.
[TouchPad Development] bobtidey:
I think there are two different things here.

As I understood it the CherryKang had the first intermediate fix which just loaded a better wifi board level binary whereas this zip loads a complete ath6kl wifi driver set. If CherryKang has now been further updated with the complete driver set then please correct me.

Some report the full driver set gives even more improvement but with maybe faster battery drain. That maybe because I don't think it has yet been fully converted to support all necessary ICS calls. When that gets done we may be close to a really good wifi driver situation.
[TouchPad Development] nevertells2:
You may be right bob, but the best person to answer this question is phil over in his CherryKang thread. I'll post this there and see what he has to say.

I'm also concerned that whatever he did in CherryKang and the update.zip might be causing a conflict.
[TouchPad Development] Animec:
Thanks a million, flashing the driver proved to be the quickest, most effective and def. most practical fix!
[TouchPad Development] bobtidey:
Good to hear that.

Could you also report whether there are any negative effects like increased battery drain as some have reported? Obviously that may be a small price to pay if they had bad wifi before but it would be good to start to quantify the effects.
[TouchPad Development] Animec:
Haven't noticed any such problems yet, but I think my wpa_supplicant goes longer between scans and it doesn't look like it's left the scanning up to the driver :o
[TouchPad Development] nevertells2:
Someone correct me if I'm wrong, but can't you change the scan rate in the build prop?
[TouchPad Development] Neejay:
Yep!
[TouchPad Development] sonjohn1:
Nevertells,

Did exactly as you suggested in Terminal and got the aforementioned error message. How do I unlock files with Terminal and is it worth the effort. I'm assuming at some point someone will figure out how WebOS uses WIFI and will replicate the settings in Android. I can wait for that, since I don't have the expertise to manipulate Linux. I enjoy messing with my Touchpad, but I'm not a programmer. Thanks.

[TouchPad Development] OwenChiang:
Thanks all, cm9a2 + wifi fixed patch fixed my office wifi problem.
[TouchPad Development] nevertells2:
Guess I didn't see the error message you mention. If you typed in the line

rm -rf /data/misc && reboot with all the spaces in the proper places, ie.,

rm(space)-rf(space)/data/misc/wifi(space)&&(space)reboot

Remember you have to type su first.

Another way to delete the wifi settings folder is download a file manager like Root Explorer or Rom Manger that have root permissions, and browse to the data/misc folder and look for the wifi folder. Delete it and reboot your TouchPad. You will have to reconnect to your AP again and enter the password.
[TouchPad Development] Mgamerz:
I removed the wifi folder some time ago. Tablet crashed like 3 or 4 times soon after attempting to bring up wifi. But it restored itself, though it wasn't much of an improvement.
[TouchPad Development] wizzbang3:
I have tried CM7 and CM9 with my touchpad.

I have a FritzBox modem (7390) and I think I've tried channel 11 and channel 6 on wifi.

It also offers 2.4 and 5ghz and both of them have the same issue.

The wifi doesn't drop out so much, as it's inconsistent.

This is EASILY demonstrated using the XBMC remote control application, with constant timeout / socket timeout errors.

Using speed test.net reveals good speeds (maxes out on my ADSL2, 15mbits, a nice low 35ms ping and 1mbit upload (max)!)

That 'looks' fine but the reality is my desktop PC can barely ping my touchpad, almost as if it has a firewall.

The touchpad springs to life and responds to pings (breifly) when it's initiating it's own wifi connection.

My wild guess is that it has an incredibly aggressive power saving mode enabled in the core driver (I don't know much about Linux but something along those lines)

The problem is incredibly frustrating - when you're using the device, many apps you don't even notice, like web browsing and so on. It's more cconsistent stuff where it falls down completely.

EDIT: I've tried at least 10 builds of CM9, I've wiped cache, I've wiped dalvik, I've wiped data- I've used "the best" of the wifer fixer apps (deletes your wifi profile after disabling and enabling wifi)

I'm convinced it's an issue in the driver, maybe even a hardware incompatibility with some routers

EDIT:EDIT - ever tried updating a touchpad when it doesn't work via USB as a drive and wifi is dead? it ain't easy. Normally re-boot into WebOS to mount as USB, copy on latest build and then flash, terriblE!

---------- Post added at 02:46 AM ---------- Previous post was at 02:16 AM ----------

I just put the LATEST build on and hte fix in this thread which might cause worse battery (sorry I forget the name?)

FINALLY I have consistent ping to the touchpad, seems a good sign as a big Android remote for XBMC! :) Will keep updated
[TouchPad Development] nevertells2:
Removing the Wifi folder is something that other folks have suggested that supposedly helped them. Like you, others say it didn't. That whole list I posted earlier is just that, suggestions from people that say one or more of the suggestions on that list helped them. The one that helped me was changing the channel on my router to channel 6. If you read that post, you would have seen what I said and could have tried some of the other suggestions to see if one helped you.
[TouchPad Development] jask0:
Hey guys. Came here to vent and to seek help! I'm at my wits end with my Touchpad. Got it about a month ago and started with CM9 A1 without any issues really. Upgraded to Alpha 2 when it came out... again, no issues really. As of late, Wifi has been crap. It's at the point where it's not even connecting at all, even after a reboot, wifi on/off toggle, airplane mode on/off toggle.

The only way I can get it to turn on is to flash a new rom and that initial setup, it works. Even so, after a fresh new rom, as soon as I reboot it, it goes back to the same where it doesn't connect at all. I've tried reverting back to CM7.1, fresh CM9 A2, AKOP Build 27 (gets stuck in boot loop) and AKOP M4. I've tried to read through this thread, but seem to be getting no where.

I've just recently tried deleting the wifi folder in the misc as well... didn't help. Same problem persists.

Can someone point me in the right direction on how to fix this issue? Are there any SOLID roms where the Wifi doesn't have issues? I wouldn't mind a CM7 or other Android rom... as long as the Wifi works. Can't really use the TP without Wifi.

Any help would be appreciated! :confused:
[TouchPad Development] jask0:
I went ahead and changed my router channel to 6 as well and this seemed to help, as my TP now actually connects. Very strange. If I bring my TP anywhere else, do all other routers need to be on channel 6 for this to work?

I'm still interested in a solid rom. :(
[TouchPad Development] calash:
You are seeing what i see from the Wifi, where after a reboot it looks like it is not even trying to connect.

My workaround, outside of not rebooting until I am outside the range of the access point, is to:

1 - Forget the Network

2 - Toggle the WiFi off

3 - Turn the Wifi back on

4 - Enter your access information again.

This fixes the issue for me every time. A bit less of a pain than reloading the rom.
[TouchPad Development] nevertells2:
@jask0, hang in there, the dev's are working on wifi drivers that should help.

I've updated my list of things to try to get wifi working, so I'll post it again:

This may not help, but one never knows. Reboot your router, ie., unplug it for a minute or so and plug it back in. Wait until all lights turn green.

Try connecting.

Several other tips to try:

1. Another obscure fix, boot into WebOS and make sure your wifi connects. Use your browser for a sec and then boot back to CM.

2. Delete your wifi profile:

start the terminal app

type su and tap enter

the pound sign # turns to a dollar sign $

type rm -rf data/misc/wifi && reboot and tap enter

For clarity that's rm(space)-rf(space)/data/misc/wifi(space)&&(space)

Reboot your TouchPad.

After your TP reboots, you will have to reestablish the SSID and password for every AP you use.

3. If you are using WPA2 and AES encryption, log into your router and change it to WPA and TKIP encryption.

4. If your router is a dual band (2.4/5 ghz ) router, log into your router and turn off the 5 ghz band.

5. If your router is wifi b/g/n, log into your router and switch to b/g only.

6. Change your router channel to either 1 or 6. Try downloading Wifi Analyzer and having a look at the spectrum in your area.

Pick either 1 or 6, whichever had the least usage.(This tip is what worked for me.)

7. Go to Settings -->WiFi --> Menu --> Advanced --> Keep WiFi on during sleep --> Always

8. Edit build.prop and add the line net.hostname=TouchPad at the end of the file.

Some routers do not like device names that are real long. You can name it whatever you want, TouchPad is just a suggestion.

9. Download Clock Sync, configure it for your timezone and set it to sync on boot.(An incorrect date or time can screw up

wifi and several other things in Android)

10. Try turning off wifi, turn on Airplane mode and then turn wifi back on.

11. Download Wifi Fixer by Zanshin-g1. It got a cheap Android tablet working on wifi when all the other tricks failed.

12. Download FXR Wifi Fix and Rescue. It's helped others when nothing else seemed to.
[TouchPad Development] Hälftebyte:
Thanks for this. Wifi's been strong for 3-4 days now. Absolutely no issues.

[TouchPad Development] kleinbiker:
Messing with the hosts file seems to mess up Wifi

CM9 03122012

Had Wifi working fine. Installed the AdFree app which inserts a bunch of entries into the hosts file. Couldn't get Wifi to connect no matter what I tried - reboot, turning airplane/wifi on/off, deleting settings.... Uninstalled app, deleted the hosts file and rebooted. Wifi started working again.
[TouchPad Development] slick_rick:
Ok WiFi is horrible for me. It literally works about 2 minutes at a time before I have to do the whole forget connection, turn off wifi, turn WiFi back on. I've tried alpha 2, nightlies, WiFi driver update, and every other Rom available. Nothing seems to work for me. Guess I'll just have to wait til the next Alpha drops.
[TouchPad Development] nevertells2:
Have you tried any of the work arounds I've posted here several times? It's not the roms that are the problem, it's the drivers for the hardware in the Touchpad running Android. Have you tried WebOS? You will find that it has virtually no issues. So as soon as someone gets the driver code right, Android will be the same and from what I have read, they are getting close. Until then, you need to read a little more. Go back to the last post on page 12 and you will find a long list of suggestions that have helped many.
[TouchPad Development] slick_rick:
Yes I have tried all your methods, about deleting your wifi profile, I've tried neejays wifi driver update zip. Yet nothing seems to work. I'll keep trying though.
[TouchPad Development] Neejay:
There's a 2.7 driver update that's supposed to be used with all nightlies starting from 3/06. I'll upload it shortly. It works with the newest kernel updates that's in the nightlies.

EDIT: temp upload: http://db.tt/aqc2GTqN After the first initial flash, you may have to toggle wifi on/off once.
[TouchPad Development] slick_rick:
Ill try it with the latest nightly, thanks.

edit: Still not working for me. I've tried just about every fix in this thread with no success. Guess ill just stick with WebOS til this officially gets fixed. Thanks though.
[TouchPad Development] nevertells2:
Just curious, have you tried CM7, Alpha 3.5?

Don't get why you are having so many problems with wifi. Where is your AP? Is it yours or do you live in a dorm or something? What does Wifi Analyzer show the spectrum looks like in your area? You are the only person I have run across that cannot get wifi working no matter what is tried.
[TouchPad Development] slick_rick:
I live in an old college dorm, but the signal works great for any other device I have. I got here once CM9 alphas had already dropped so I haven't tried CM7. Is wifi analyzer a market app?
[TouchPad Development] nevertells2:
Yes, Wifi Analyzer is on the market. The fact that you have no control over the router that provides your wifi signal in your dorm explains a lot. I have seen many college students say they have a lot of problems with their college wifi. I'll bet it works fine with WebOS. Don't waste your time trying CM7, you'll have the same problems. You might want to try CherryKang version 0.9.1. you'll find it here:

http://xdaforums.com/showthread.php?t=1488561

I remember a couple of college students saying that it got their wifi working at least enough to use it.
[TouchPad Development] slick_rick:
Thanks I'll give it a try.

Edit: Well it looks like it may be my schools wifi after all. Im tethering from my epic 4g touch and its working great. Thanks for all the help, ill flash the latest nightly and use that.
[TouchPad Development] silvacrest:
i think im gonna sell my touchpad i have tried different roms, the supreme update as well as neejays wifi fix but its to hit and miss for me to use

[TouchPad Development] hutc:
wifi issue

well i reinstalled the whole partition of android and i realised that wifi was not at all working after the second boot, this is after 2 weeks of cm9 alpha 2 usage(i tried to clean the partition and reinstall) the wifi after initial success was not budging at all , this is what i did

1) installed the latest driver as above mentioned in the above posts and wifi worked with more battery consumption

2) then i synced the time of the touchpad to the exact time of the location,earlier what had had happened due to time change in usa after that my wifi was screwed ( before that it was great)

3) then i installed the super mod 1.3 again through the recovery and after that i followed the instructions and currently wifi is working great with minimum battery consumption.

i think syncing the time is the first thing you should do as early as possible to keep the wifi intact
[TouchPad Development] nevertells2:
Kind of a brash statement. What seems to be the problem? You weren't very descriptive about your problems and what you have done to resolve them.
[TouchPad Development] wizzbang3:
While I don't intend to sell my touchpad, I understand his frustration.

I've used CM7, CM9 and about 20 different nightlies and alphas on it, I've tried the ath6kl wifi fixes (2.6 and 2.7) I've wiped (thoroughly) the device from scratch and re-installed (including in different order of installs)

I've changed the channel on my router, I've attached to the 2.4 and the 5ghz channels on my router. NOTHING will give me sure fire, standard reliable wifi like my BlackBerry, Laptop, Galaxy S2 or HTC HD2. The touchpad has serious wifi problems.
[TouchPad Development] eyeb:
don't know if it's been mentioned but for the people that get wifi connection, go to advanced settings and always allow wifi connection even during sleep, then it won't loose it and you don't have to mess with reconnecting it, i lose about 1-2% a hour doing this not very much, about 9-10% over 9 hours of sleep :S and I get around another 5-6 hours of use, then i charge while sleeping
[TouchPad Development] arozer:
What exact Wifi issues are you guys having, that's frustrating you so much?

My Wifi issue is:

If I don't use my touchpad for a few hours and I come back to use it, my wifi will get disconnected.

All I have to do then is: go into settings, wifi, click on my wireless connection, hit "forget" and re-type the password and it works fine.

If that's the same issue you're having, then that's not SOO bad.

It's an easy fix.
[TouchPad Development] slick_rick:
I was having the same issue but it was 10x worse to the point where I was only using WebOS. I would connect to my wifi, it would work for literally 1-2 minutes and then I'd have to forget, turn off wifi, turn on wifi and connect again. Then once again work for a couple minutes and repeat cycle until I got tired of it and went back to WebOS. Problem was my dorm wifi router. Tethering from my phone, I never lose connection so its all good.
[TouchPad Development] nitrobg:
Why don't you wait until July before doing anything which involves getting rid of your Touchpad? It's a wonderful device for a extremely cheap price.

Wait until July, HP has promised to release the source for system manager bus and core apps in WebOS, after that the developers will be able to port the necessary correction to make Android's wifi working as intended.

Until then - don't whine and do your best to support the developers.
[TouchPad Development] nevertells2:
Actually, wifi on the WebOS side is solid. No one is saying that there isn't a wifi problem with CM in general. I'm sure you have seen my list of things to try. There are two apps on it that have helped a lot of folks. Many folks say that using the CherryKang rom has gotten them a wifi connection when all else failed. Is the only AP you have tried is yours? Have you tried some free places like the library or Micky D's? I am aware of guys who have gone out and purchased a new router and now their wifi works. Several folks have said the latest official nightly has the newest wifi code and are happy with it. Might want to give it a shot.
[TouchPad Development] Blueness88:
Wifi working

I can vouch that my WiFi works solidly at home on the latest CM9 Nightly (3/29). I had to set my router to use channel 1 which magically made it connect 100% of the time. Knowing WebOS's wifi works flawlessly, I know the problem lies with the current CM9 build, which will probably be resolved over time. I think CM9 may be having wifi issues across the board but i'm not entirely sure.

I can't really say if my CM9 Touchpad connects to random access points well since i've been only testing it at home, but for the price, the touchpad is a steal. I wouldn't sell it just yet. :)
[TouchPad Development] wizzbang3:
If you're an infrequent user, sure it's not so bad.

If you use it regularly and want to replace a laptop for some functions, may as well just sit and wait for Windows to load...........

Also the speed is inconsistent and the reliability (without this new driver)

I just got 500kb/s sustained from it... 500kb - sitting 4' from the router. My Galaxy S2 gets 1.5mb/s sustained and my laptop 6mb/s.

I'd be happy with 1.5mb even but 500kb and inconsistent? cmon.
[TouchPad Development] slick_rick:
To anyone having very bad disconnects on their TP constantly having to forget network, turn off wifi, turn on wifi, repeat. I've seemed to have found some ways my Touchpad performed better that might work for yours also. I live on campus on my university so I guess its the way my dorms wifi is set up but I would have problems on their network with very constant disconnects. One thing that does work for me is tethering straight from my phone using the wireless tether beta 11 app. Idk what it is but I never get disconnects using it so maybe you should see how it works for you. Another work around I found is a bit more complicated but easy to do. What im basically doing is taking my dorms wifi (the one that barely works at all on my TP) and then turning my laptop into a virtual access point for my TP to connect to. And guess what, it works PERFECTLY! No disconnects whatsoever. Idk what the difference is just straight connecting my TP to my dorms wifi and it performing horribly to connecting to my laptops virtual access point (which is basically resending out my dorms wifi).

1. go to http://www.virtualaccesspoint.com/ and make up an SSID and WPA2 key for your access point

2. follow the steps on this website http://wlanbook.com/windows-7-internet-connection-sharing/ to set up internet sharing connections.

3. enjoy

This is for Windows 7 but im sure its similar to XP or Vista. I know this post is kinda confusing and hard to read but im sleepy from chem lecture lol. Let me know if it works for you because its working great for me or any questions.
[TouchPad Development] nevertells2:
Sucks to be you!!:o Just checked mine and smoking along at right around 10,000kb both upload and down. BTW, that's using CM not WebOS. And I get that consistantly.

Just checked my other TP, and I'm getting 14500kb down and 11600kb up. Oops, almost forgot, I'm sitting in the other end of the house from the router.
[TouchPad Development] beckitach:
My TP never really stays connected to my school's wifi no matter it was under CM7 or CM9: after like 2 or 3 minutes, the wifi bar is still there, but it never communicates with Internet any more. However, it could stay connected under webOS.

p.s. It works perfectly with the router at my house.

Since there's no way for me to change settings on school's routers, has anyone experienced similar issues and found a way/mod that solves the issue?

(I'm guessing it's because that there are many routers all over the campus sending out the signals which confuses TP. Just a random guess :P)
[TouchPad Development] bobtidey:
When you can't help things by router settings then I think the two main things to try are Cherry Kang ROM which includes some slightly better low level wifi drivers and/or the athl6 new wifi driver set 2.9 which is referred to in an earlier link in this thread. Quite a few people have experienced good results with these.
[TouchPad Development] slick_rick:
If u want, try what I said a couple posts above you. I live on campus and experience the exact thing with my schools wifi.
[TouchPad Development] bobtidey:
Although I think we all want our Android Touchpads to eventually get as good from a standalone wifi point of view as WebOS using a tether or local virtual access point can be a method which works for some when all the other software / config methods have failed to give good stability.

If one does not have a laptop in the local environment then nano routers like the Edimax BR-6258n might be another option. These are handy devices to perform all sorts of wifi related tricks like a regular router, repeater, bridge, client etc.

They are cheap ($25-30) tiny low powered devices (can run from a USB port). I carry one of these around with me as part of my portable networking toolkit.
