Ad-Hoc Wifi on Acer A500 Tablet (Honeycomb)

I was able to get wifi tethering up an running using the information in these posts:

Enable Ad-Hoc wifi access using these instructions:

Worked very smoothly and it was my first foray in to Android and rooting....
BTW... I am tethering to a WinMo 6.5 phone using WMWifiRouter. It works nice too!!

Thanks for pointing out the thread that worked on your A500. I am going to try it this week. I'm also new at this and have been able to root and do a few other things thanks to everybody that posts the great walk-throughs here.

I got adhoc working on my A500 also (tethering to a jailbroken iphone with PDANet). I was running into issues trying to run the ADB REMOUNT command, with the error "Operation Not Permitted" being returned. There is probably a more skilled & elegant way do do this, but I modified the instructions I found here:
You need to turn on Airplane mode to disable wifi, or you will get an error when trying to copy the wpa_supplicant file with ADB PUSH later on in the instructions...
adb shell
# su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# chmod 777 /system/bin/wpa_supplicant (Or any subdirectory you want to push to inside system)
# exit
adb pull /system/bin/wpa_supplicant <local path on your computer> (this is to backup your original file in case you have to restore it)
adb push <local file> <device location>
and eventually you should restore the original directory permissions by going back into the shell:
# chmod 755 /system/bin/wpa_supplicant (Or any subdirectory you modified permissions to)
Now turn off Airplane Mode, and give it a test.

I also got adhoc wifi working on my A500 too by manually update wpa_supplicant via Root Explorer since the Acer new OTA version Acer_A500_1.126.03_COM_GEN1 still don't fix this issue.

I accidentally did it without turning the wifi off, now wifi doesn't work. Is there a way to recover it?

That's weird, it wouldn't even let me overwrite the file unless airplane mode was on (disabled wifi). If you made a backup copy of the file, just restore it. If you didn't, here's my original backup (which is not modified)....be sure to unzip it first before using it though.

Nothing, still get the same error, i think something happened in some other files because it was connected when i changed the file. Any idea of what could it be?

What error are you getting? I would also try rebooting your tablet. I am, unfortunately, no expert at this...I've only had exposure to honeycomb for 5-6 days now. So, I'll have to defer to all the experts in the forum.

I even tried a factory data reset but still get the same error, it just doesn't connect.

Any idea of what could be the problem?

Maybe i should wait for the os update?(can i do it without internet connection?)

A500 rooted/recognizing wifi, but pages don't load
I followed the steps: rooted my A500, uploaded the wpa_supplicant file, changed the permissions. I use WMWifiRouter on my HTC HD2 phone. Now, my A500 recognizes the ad hoc wifi and connects, but the browser fails to download any pages. My Acer netbook (Windows) works fine using the same connection. The A500 has Dolphin, Firefox, and pre-loaded browser - none of them will download pages. Also, the A500 browsers work fine on my home wifi and other wifi networks. Just not on the ad hoc wifi. Any ideas?

Damn, it took me hours to stumble upon this thread, but thank god I did! Now I finally have ad-hoc wifi working, though I couldn't follow the instructions: adb just kept complaining about device not present error. Had to do it another way.

Dear Sir
I have same problem with you.
My cell phone is HTC tough diamond and the soft is Windows Mobile 6.1.
My A500 can link with my cell phone but can't run browsers neither internet.
How do you conquer this problem? Can you share it?

Pretty sure your issue is with permissions.
I used a terminal app and entered the following for permissions w/ wifi disabled:
su root
chmod 755 /system/bin/wpa_supplicant
chown system.wifi /data/misc/wifi/wpa_supplicant.conf
Reboot and try again.

I so want to do this, as I could really use a WiFi AdHoc connection, but do not want to brick my WiFi. Are there a few other people who can confirm this as working?
I am using Acer_A500_4.010.13_COM_GEN2. Thanks

I have the same problem. Someone did it fix?

This worked for me using root explorer. Thanks for the post, I was getting a little mad that the ipad could see my phone but the a500 wouldn't see it.

[Q] Ad-Hoc

Greetings to all. I have ROM prime 1.6. At me such problem. There is no return through wi-fi. Speed of return - 0. An access point - Ad-Hoc, created through Connectify me. What can it be? Forgive for my English

I'm not sure if ad hoc is possible on the Transformer. I've tried rooting mine and changing the wpa supplicant file with one that was supposed to work. No luck.
If anyone else has a way to get the Transformer to connect via ad hoc, I'm all ears.

Used a custom kernel?

I have my Asus transformer connecting to my iPhone which uses an adhoc type of connection
All ive done was add the wpa_supplicant to my Asus's System/bin and replaced the WPA that was there... oh by the way backup the old one before u replace it...

yout will need root access, root explorer and the modified Wpa_supplicant file

I used the search feature of this forum and found this for you -
adhoc thread 1
adhoc thread 2
adhoc thread 3
Mine works fine with my Hero running an adhoc spot.

Interesting... can I just confirm something?
So in order for my TF101 to detect and use Ad Hoc connections, i must do the following.
1. Root my TF 101
2. Replace the wpa_supplicant file
3. Have my Nokia 5800 run JoikuSpot
4. Done!
Sorry, i'm really new to this.

[Q] anyone have the original wpa_supplicant file for p6210, wifi stopped working

So, i did something stupid and followed instructions to allow my samsung tablet gt p6210 to accept ad-hoc wifi tethering from my smartphone. it said to replace the wpa_supplicant file with another one and ever since the wifi won't turn on. i made a system back-up before, using titanium backup, but even when i restored it, nothing worked. i'm wondering whether doing a factory restore will help? or if anyone can give me a working wpa_supplicant file (the original) so i can have my wi-fi back. please!

Ad-hoc wpa_supplicant

Has anybody looked for, or found a working wpa_supplicant that allows the tab to tether off another device?
D
.

I've been hoping for that. If only someone would make one...

FWIW - I tried a lot of things to get tethered to my Droid X. I finally settled on WiFi Tether for Root Users which puts the X in the infrastructure mode.
You probably already know this: http://www.xda-developers.com/android/android-ad-hoc-wireless-network-support/
What's the advantage of ad hoc over infrastructure?

Samsung Tab 2 10.1 w/ 4.0 ICS - cannot access adhoc networks
I just got my Tab 2 10.1 with 4.0 ICS. I rooted it and then tried putting the wpa_supplicant file mentioned in these forums in the system bin directory with permissions of 755 while in airplane mode. When I reboot, and try to turn on wi-fi, it just hangs with "Turning Wi-Fi on..". When I put the original wpa_supplicant file back and reboot, everything works again.
I notice that the patched wpa_supplicant file is only 295,964 bytes long whereas the original wpa_supplicant file is 569,140 bytes long so it would appear at least that in ICS there has been a lot of code added?
Is there a wpa_supplicant file that allows adhoc mode that works on the new Samsung Tab 2 10.1 with 4.0 ICS?

I ran into the exact same issue
I went back to stock

Really need AD-HOC...
...because my phone cannot tether in infrastructure mode !

i've been using that app from my ns4g. works like a charm.

I have exact the same problem.
Hope for a solution (a working wpa_supplicant file)

Has anyone run across a solution to get Ad-hoc working on the Galaxy Tab 2's? I've tried numerous wpa_supplicants, numerous ROMs, searches, etc. with no luck...
Thanks.

Same here. Feel desperate.
I googled for 3 days with no luck. Try serverl wpa_supplicants resulted in a halted "turn on wifi"...
I know there is a solution in os 2.3.6(coz I tried it before on a old tab P1000)...
is it possible to downgrade a Tab 2 (P3110) from os 4.0.3(stock) to 2.3.6??

The reason I need this:
I got an iphone 3GS which can ONLY setup an ad-hoc network for my tab to connect to.
(while an iphone 4 can share in infrastructure mode)

Need help
Hi there,
Would someone PLEASE upload their original wpa_supplicant and send it to me, has i obnoxiously failed to backup my original one before attempting to use a 3rd party wpa_supplicant?
My wifi still isn´t working AT ALL.
I´m using a 7 inch galaxy tab 2 with android 4.0.4
THANKS!!!!

I suffered the same problem...just dont bother to load wpa files etc.....
flash stock firmware....thats it !!!
theres not much to do when files are corrupt....

[Q] adhoc problem in cm10.1.+/4.2.+

Anyone use adhoc? Have it working in 10.1.+/4.2.+ ?
I've tried all wpa_supplicant files I could find with no luck.
I can't get the a700 to see my adhoc ap.
I've got a working wpa_supplicant for a200/ics.
Otherwise I'm happy with
A700/cm10.1.1 stable/kitman v4.1 kernel(3.1.10+)
