My touchpad hates connecting to wifi but recently its been better...
[TouchPad Development] fast96:
I have posted this elsewhere, but I've had wifi issues on a couple of android tablets before, now I do not. The only work fix I've found is to install clock sync , and let set the date and time on boot. Check the system date when you cannot connect to wifi, I think it is a bug in most android builds. My system date occasionally would change to 1-1-1970, and would either not connect, or would throw certificate errors when connecting to sites.

I wish someone who has wifi issues consistantly would try this, and post back. It can't hurt to try it. Clocksync is free.
[TouchPad Development] Neejay:
I'll try it when I get home from work today...thanks.
[TouchPad Development] Animec:
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 :)
[TouchPad Development] Nizda1:
Interesting solution, I will give it a try when I get home in a couple hours. I believe it will definitely fix one aspect of all the issues were seeing. I actually noticed the other day while reviewing some logs that after my wifi cut out or when it could not reconnect after a reboot there was a long string of errors trying to obtain the time.

Thanks, ill let you know if this helps, I also have to set the wmem tcp defaults higher as an easy test using a speed test like the app for instance knocks mine out on the first packet by sending one twice the size of our min 2048 too low.
[TouchPad Development] dahauss:
Tonight I tried both solutions and so far no wifi drop
[TouchPad Development] dahauss:
No go. Dropped and a reboot is only way to get it back
[TouchPad Development] Konowl:
So I installed the clock sync program and everything has been working great so far. Very strange. No dropped connections, I can turn Wifi off and on at will. Before I installed the program, the wifi was brutal - only a power off and reboot would let me connect.

Interesting solution so far, will monitor and see if it pans out.

What are some good ICS compatible launchers? i hate the one that comes with CM9.
[TouchPad Development] Neejay:
:D:D:D:D So far, after about 3 hours, no wifi dropping.

This didn't work for me, although I didn't try "1" yet, only "2".
[TouchPad Development] dahauss:
None of these solutions worked.
[TouchPad Development] Animec:
Sorry to hear it :(

Worked perfectly at school too. Connected immediately and no overt or secret drops. I decided to experiment some more and found that the wpa_supplicant file was reset whenever I restarted wifi, leading to problems. Mucked around some more and have now gotten it "working" reliably even after restarts and reboots by setting update_config=0, granting ownership of the file to system.wifi and clearing caches. No doubt some of these steps are extraneous but I'm too ignorant and too lazy to figure out which. Input would be helpful! The problem with this method is that I probably won't be able to add new networks with update_config=0, but I'm happy that it works well at home and at uni.

This is good since I don't have authority over the uni's IT-people :)
[TouchPad Development] Neejay:
1 day later and my wifi hasn't dropped yet.

+1 for solution of "clock sync" set to "on-boot".
[TouchPad Development] dahauss:
Didn't work for me.
[TouchPad Development] ray2jerry:
ditto, clock sync didn't work... Which makes sense if you think about it considering it needs a connection to sync :rolleyes:

Will try some of the other suggestions... Too bad too, it's otherwise running like a dream!!

I've compiled a list of things that help me and others. The channel change is what help me. Here is the list:

*********************** Paste ************************

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.

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 FXR Wifi Fix and Rescue. It's helped others when nothing else seemed to.
[TouchPad Development] fast96:
Good stuff "nevertells2", anything that will help wifi, makes the tablet experience better, for sure.
[TouchPad Development] Mgamerz:
Your remove wifi profile assumes system is already read write. What's the command?
[TouchPad Development] calash:
/data is writable as root, no need to remount.
[TouchPad Development] Mgamerz:
Hmm... I guess I followed a diff guide under system. Either way it said read only. Maybe I wasn't superuser... pretty sure I was...
[TouchPad Development] jmouw:
My wifi was freezing every20 minutes our so on both cm7 & cm9. I have two connected wifi routers in my house and I noticed it cut our on one primarily. I changed the channel from 11 to 1and I set it wireless G only. This fixed the problem for me.
[TouchPad Development] dahauss:
Well, in my case, and probably in a lot of peoples cases, we dont WANT to switch to "G" only. I have other devices in my house that use N. Also I have the same issue at work with some APPLE AIRPORT DEVICES which are "G" ONLY (NOT N)....

There has to be a fix for this wireless issue. I wish all developers would STOP building any features to their ROM UNTIL we can get the WIFI ISSUE WORKING. if not, I think I am just going to use this as a WEB OS tablet and go get a new tablet (EITHER ANDROID OR IOS).....
[TouchPad Development] Neejay:
I actually flashed an update to our wifi driver...the only catch (of course...) is that it drains the battery faster. But I'd rather have working wifi than a useless tablet with 100% battery life. This was a last resort effort for me, as I was ready to just sell mine.

USE AT YOUR OWN RISK, CREATE A NANDROID BACKUP FIRST, I ACCEPT NO RESPONSIBILITY.
[TouchPad Development] kosumo:
Another solution is to try one of the last nightly build

I installed the "update-cm-9.0.0-tenderloin-KANG-20120303-0600-signed.zip" on saturday and the wifi is great. Connection is fast and no disconnection in 48h.

the black point is that the nightly build can be less stable than an alpha :cool:
[TouchPad Development] jmouw:
Understand. I'm just happy that I don't have to keep switching the wifi off and on every twenty minutes.in my case I narrowed it down to one of those 2 changes(channel & G>N) and have had a dramatic change. In using cm 9 with wifi set to "always on".

One point of interest is I noticed for me that it wouldn't freeze if I was watching netflix. I could watch a netflix movie without it freezing once before the fixed.
[TouchPad Development] Mchasard:
im running todays nightfly and wifi seems to be better...but not perfect ...

Thanks for thé info
[TouchPad Development] nevertells2:
I think that everyone needs a reminder that CM is experimental/alpha software. Expecting every aspect of it to work flawlessly at this point in time is ludicrous. We should all be grateful that the developers even considered releasing it before all the bugs were worked out, otherwise we would all still be waiting. They put in thousands of hours doing this and all they expect in return is a little gratitude. Complaining and demanding that certain aspects of the operating system be repaired now just shows that one doesn't really appreciate what alpha software is all about. It is provided with out warranty. You use at your own risk, you test, play, and report back your experience with the hope that helps improve the end product. If you can't live with this prospect, please uninstall CM and enjoy the WebOS experience. Come back in a year or two when all the bugs have been worked out and give it another try.
[TouchPad Development] dahauss:
I can live with EVERY BUG EXCEPT WIFI.. you cant use the tablet without it.. EVERY ROM I have FLASHED on the TP has the same WIFI ISSUE. Im going to try to updated driver and see if that works. BUT to wait a year or two is crazy. I might as well go get another TABLET....
[TouchPad Development] robrob777:
If it helps..

Guys if it helps, I'm using a Netgear router (it is white and has only B/G, channel 2 only and WEP)

I always hear in forums, my iphone/ipad/android etc doesn't connect to my router, and a lot other devices, but all mine work perfect with my router including the touchpad.

Actually I have my wifi sleep policy to "only when connected" so it disconnects by it self when sleeping (after like 45 min) I notice that it doesn't connects back when I turn it on, but I just have to toggle it, I have a widget for that and it does it in less than 5 seconds.

I have the same or better battery life than with webos with this policy. (WIFI/ touch the 3 dots in the right-up corner, advanced, sleep policy)

I'm running CM7 nightly but it was the same with 0.6 and A2.

I use the touchpad most of the time that I'm doing something online, I kinda don't my computer or phone, so it is my daily driver.

Thanks
[TouchPad Development] dahauss:
Didn't do anything for me. I'm running an ics build. almost time to give up and get a real tablet. If I were to get one, which one do you suggest?

---------- Post added at 08:58 PM ---------- Previous post was at 08:41 PM ----------

Can someone post a WIFI DRIVER ZIP and a KERNEL ZIP both flashable that will work with CLASSICNERD BUTTA ICS for the TP??
[TouchPad Development] Nizda1:
One common theme I've come to realize about these wifi issues and some of their respective solutions all lead to the tcp buffer overflowing resulting in wifi crash. Now that can be temp workaround by tweaking some tcp values and in other cases reducing speed/throughput by switching to b/g..etc. At home I use a Linksys 3200 dual band router and I don't turn the 5ghz off and use either chan 9 or 11 and it works fine for me. Tested under mixed and n only both work fine as I would never switch to any combo without n and sacrafice the speed of every other device. Wifi analyzer app which I'm sure most have heard of, when I occasionally lose signal I always notice mass interference on the specific channel I am on. In my case that's usually 1 or 6 as it seems my entire building defaults to them. For those of you that experienced a "fix" under switching to 6 or 1 or whatever when you use the app do you notice that the channels that seem to fix the issue are the least crowded? To those having issues I would say use the app as intended see if it works. Although unfortunately the bottom line is the current drivers are not stable which is well known and being worked on. If wifi flat out has been a complete nightmare with the device then it could also be that the TP in general does not always play well with routers that don't have broadcom chipsets, which I've read too many occurrences to be an anomaly. Lastly for those with working wifi on N are you able to use say speedtest.net app without it crashing your wifi? If it does, attatch a logcat as I am working on a more stable temp fix for atleast this issue until the new drivers are done. Btw. Something I found interesting I was able to connect at 150mbps while messing around which I didn't even know was possible with this device, anyone else ever get above 72mbps?

For the post above me there are so many nice tablets coming out I would wait but if you don't want to it really depends on how much you want to spend, but I have a xoom that works awesome and a galaxy tab 10.1 both excellent.

[TouchPad Development] minimonkey7:
I like many others have been having Wifi Issues and I refuse to change my router settings, I think implementing this has helped towards resolving all the Wifi problems.

First put this on Alpha2 using root browser lite (free) then installed the nightly update-cm-9.0.0-tenderloin-KANG-20120302-1426-signed.zip (this seems to keep the ap_scan=2 after reboots/don't know why) and later nightly's have broke the Wifi.

Second I installed Bricked kernel v65 #68

Third I installed the SUPREME Mods v1.2

I have also installed after these: the Battery mode, Boot animation and ts tracking.

I have connected to about 4 different Wifi networks now with positive results even after reboots and disconnects.
[TouchPad Development] InSaiyanone:
I currently use CM9 w/cornerstone build and even though I have wifi issues here and there I just find a few restarts and turning on wifi usually gets it up and running. The build I use has "dev tools" included so I just crash the system server (I learned that from having a SonyEricssonX10) which just restarts android instead of the entire device. Sometimes I don't need to do that when switching from webOS, other times I'll have to do it about 3 or so times after checking if it actually connects to the AP. I have no issues seeing the wireless networks just sometimes it won't connect but once I see it trying to acquire an address I know I'm good.

including #10 and nothing gets your wifi working? If that is truly the case, I'll be happy to buy your TP and put you out of your misery. Just don't expect to get much for a TouchPad that won't connect to wifi.
[TouchPad Development] dahauss:
Well...formatting and loading the new classicnerd. Ice solved almost all my issues. New version came out last night and someone on the irc for this rom helped me and now I have a great tablet. Wifi works both home and work with no disconnects.
[TouchPad Development] OwenChiang:
Kindly could you help tell more detail how you fixed your problem? I got two set of TP both got problem connect to my office wifi but working fine on my home one. I dig out a old buffalo G45 router and change the setting as people recommended (channel 1, wpa..etc) still no luck.

I did try serveral roms like alpha0.6, cherrykang and alpha2.0 all got the same results.
[TouchPad Development] ArmanUV:
My only problem with wifi is that I have to turn wifi off and then on everyone I unlock my touchpad. Does anyone know a fix for that?
[TouchPad Development] nevertells2:
Guess you won't be selling me your TouchPad.:mad: However, I've got some bad news for you, one, there is absolutely no difference in the way Classicnerd folks build their rom compared to CM when it comes to wifi. If fact if you read the thread far back enough, you will see they have the same wifi issues too. Second, CN does not have HD acceleration working yet. So have fun over there in CN country. Let me know if you change your mind about selling your TP.
[TouchPad Development] dahauss:
Ok well I had cm and couldn't get wifi to work at all. It dropped every 2 minutes or so. the latest cm doesn't. Maybe the latest cm works too. I like Cn
[TouchPad Development] Chinpokomon:
Not crashing when using speedtest.net. I'm on channel 64 and pulled 25Mb/s up and down. I'm not sure why my setup is so special. Details about my setup can be found in an earlier post in this thread.
[TouchPad Development] ankorez:
hi all

i'am in CM9A2

my problem is that the wifi logo shows activity constantly for no reason

dont understand why...

this problem persist since CM9A0.5 for me...

it uses much battery

in catlog i have this message

I don't know if this is related
[TouchPad Development] gtg2:
Praise Jebus! It's finally working again. Thanks!
[TouchPad Development] nevertells2:
Your TouchPad is constantly syncing with Google, Gmail, your other email servers and any other apps that communicate with their servers. So no doubt you are going to see activity just about all the time. If you are not using wifi, turn it off and save battery power.
[TouchPad Development] Ratix0:
I've got a quick question.. I understand that android, by default, is unable to detect and use adhoc networks. However after doing some googling, there were patches released for froyo by some xda communities to enable usage of adhoc networks.

I'm curious if there are similar things, patches or whatever that I can do to allow my touchpad to use adhoc wifi networks?

Also, I seem to have pretty good wifi, no issues at all with CM9 Alpha 2. :)
[TouchPad Development] XBrav:
So my wifi issue seems to be that it can see all APs but cannot connect. Multiple reboots never fixed it. Tried turning wifi on in airplane mode and it worked!
[TouchPad Development] Nizda1:
What type of error or do you get when your able to see the AP but can't connect. If you don't see a clear visible reason/error. Try using lumberjack from the market it will allow you to watch your logcat, event radio etc at the same time. Also for anyone that doesn't want to go into terminal its a easy gui. For me I have been getting excellent connections using 5ghz and ill have to look into this further but have yet to had a forced loss of connection on that spectrum. Most likely an anomaly. :)
[TouchPad Development] ankorez:
I don't think because same problem after full wipe without set up google account
[TouchPad Development] nevertells2:
So you think that just not activating your Google account is going to stop the numerous apps that come installed in Android from pinging the web for information? There is a lot more going on besides your Google account. When you have wifi turned on that means it is using battery power because the wifi radio is transmitting to the AP and receiving information from the AP. Do you have a laptop? Watch the wifi activity on that sometime. It's busy all the time. I did notice that the CM team did change the wifi symbol and the way it behaves in CM9. CM7 did not have the little activity indicator like CM9 has. That is probably why you think you are seeing something more happening when it has been happening all along.

For the 1st time ever I get a wifi icon that says I have an excellent connection. The only problem is that it won' connect to the internet or finish registering my google account. I'm on Cherry Kang 9.2 with the Atheros wifi fix. Any suggestions?
[TouchPad Development] Cubicsilver:
That's because you have to delete /data/misc/wifi and reboot.

It will clear out the old wifi settings and allow you to connect again.
