Guide Wifi Ad Hoc Working Samsung 10.1v

[drnackers]

Hi Guys,

I have just gotten Wifi Ad Hoc connection working in the Samsung 10.1v (don't see why it won't work on the 10.1 either)

You need to have adb installed and your Tablet needs to be rooted.

I used 2 threads as reference for making this work:
http://forum.xda-developers.com/showthread.php?t=1069569

and
http://forum.xda-developers.com/showthread.php?t=1033314

As a newbie to this i will show you what i did, maybe someone can clean up the process with a simple approach:

You need to turn on Airplane mode to disable wifi, or you will get an error when trying to copy the wpa_supplicant file later on in the instructions...

I had trouble with the adb push command (shown in the above threads) so I did this instead.
Unzip and copy wpa_supplicant file (attached) to Tablet (I used downloads directory)

Get ES File Explorer from Market
Open ES File Explorer and in settings menu select Root options.
Set Root Explorer and use HiAPK
Then Tick Mount File System, then exit menu and navigate to /system/bin and copy wpa_supplicant to somewhere safe (I made backup directory in storage/ sd memory)
Now copy new wpa_supplicant file from where you saved it (downloads directory) to /system/bin

Now in windows command box type:
adb shell
# su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# chmod 755 /system/bin/wpa_supplicant
# chown system.wifi /data/misc/wifi/wpa_supplicant.conf
# exit

Now reboot and turn off airplane mode and enjoy.

Usual conditions if you follow this and something bad happens please don't blame me i used the above method (with trial and error) which worked for me (but maybe i just got lucky)
Also I want to acknowledge the hard working devs that pioneered the process and created the file - great work!!

Good luck...

what about the usage of battery after install that wpa_supplicant.conf

Because i used to transfer a similar file like wpa_supplicant.conf to help my samsung Galaxy S i9000 to connect the adhoc WIFI. The usage of battery is horrible, I charged my phone whole night and there is no more battery remaining next morning

 

[drnackers]

I will keep you posted, but been using it on ad hoc for a couple of hours now and nothing out of the usual. Battery seems just same as on wifi.

I will leave it on overnight and report back tomorrow

OK well it has been connected all night to Xperia x10 running barnacle no issues downloading through swarm bittorrent client.

Battery was 78% now at 58% so I would see this as acceptable.

Only 1 issue I have noticed, every time you connect to ad hoc it asks for password and adds it as new connection, so you end up with a few in the list but hold on old connections and 'forget' works fine

woooo! Wonderful!

I had used the ad hoc wifi and knew that issue already. Anyway, thank you for remining!!

Maybe something should do with the usage of battery, because there is 20% drop during the whole night.........

well, in that case, my cellphone cannot tolerate it

 

[chesterchen]

just installed the JuiceDefender app on my 10.1v.

before that, the wifi/3G standby overnight will consume about 10% of battery.

after installing it, and the night more, it went down by 4%.

2nd day of using it and battery life SEEMS better.

I created a zip flashabile on recovery, we'll post it and put it in the first thread?

 

[DroidHam]

Anyone try this on 10.1?

 

[rs125]

Anyone try this on 10.1?

I haven't tried but it works

 

[baggenismo]

I cant seem to get it working right...
After following these steps my wifi drops every 10 seconds... It will see the adhoc though ;-D
I have to disable wifi and re-enable then it will auto join a network for another 10sec before it drops. any advice?

 

[nick7920]

I used adb and it worked "MAKE SURE THAT YOU LOCK THE PERMISSION with CHMOD 755 or it will not work"

put the tablet in airplane mode
I download the file put into C:\ of desk top
I had backup my original by using adb pull /system/bin/wpa_supplicant
these are commands and responses

Tried the flashable zip using cwm 4.0.0.4 but I keep getting installation not successful message. The installation starts, file is opened but the result is unsuccessful. Any suggestions?
10.1v /unlocked / rooted / cwm 4.0.0.4

Edit: Just saw the manual push method above. It will just be so much easier if the flashable version would work.

 

[mattXdezzi]

pushed to system/bin w/ root explorer and edited permissions with RE too.

works so far on my 10.1 retail rooted

Works perfectly. The only thing different is the file size reported. Typo?

I have exactly the same issue. I did this same procedure on my galaxy tab (the original 7" one) and it worked great. Replacing the wpa_supplicant file on my galaxy tab 10.1 has the connections work for 10 seconds and then drop. Incidently, I find this is true for all connections (ad-hoc and regular). Switching back to the original file fixes this. I've played around with the config file in /data/mis/wifi/wpa_supplicant.conf and added ap_scan=1, but I've had no luck. I have the 16 GB retail version. My version also had a locked bootloader. Any suggestions would be most appreciated.

Thanks,

Ben

I don't seem to have this problem of wi-fi disconnecting on my 10.1v. So far working perfectly with Connectify, even when the device has screen off, connection seems to persist - I did select never switch to mobile data from settings. I don't know how long it will stay connected though, haven't done a time test yet.

My tablet is wifi only. Perhaps this is the issue. Has anyone gotten this to work who has a wifi only tablet (retail edition)?

 

[tiltyu]

does not work...

 

[makbil]

Left the tablet aside for an hour. I unlocked the screen, and instantly opened the web browser. The connection was working. So maybe it does have something to do with 3G connection even though it is turned off. I am using Connectify (free version) on my notebook.

 

[mattXdezzi]

Just thought of something. I have juicedefender set to turn off 3g when my phones screen turns off. This could cut connectivity without dropping wifi signal. Will test theory tomorrow...
