[Q] Enabling ad hoc mode for wifi tether?

Recently upgraded to 1.2 using MN 4.5.18 and I've been reading how the supplicant is different. Does any one now of a working patch or process to get this working again?

adhox fix
down load wpa_supplicant.adhocfix.
Backup current system/bin/wpa_supplicant
rename wpa_supplicant.adhockfix to wpa_supplicant
replace current file with new file.
Reboot.
You should see adhoc connections at this point. There is 1 bug though, once your unit goes to sleep, the wifi needs to be reset once woken up.
I found a program that you can download for free from the market that worked for me, that resets the connection automatically after wake-up. "blade wifi fix"

Thanks. Now, I saw those posts but they were saying that the wpa supplicant in 1.2 is not the same as it was for 1.1 and previous.
If it does (and just I'm finding exactly what you're talking about) can put up the link to files you used?

Adhoc connectivity (wpa_supplicant)

adhoc connectivity worked on galaxy s2
this trick found from another thread
you need a rooted phone & root explorer
1. Unzip the file attached here (wpa_supplicant.zip) and send wpa_supplicant to your phone.
2. Using Root Explorer go to the folder were you save it (wpa_supplicant) and copy the file.
3. Using Root Explorer, enter the /system folder and press the Mount W/R button (upper right corner)
4. Now go to /system/bin and backup your current wpa_supplicant, and paste the new one.
5. Set permissions to wpa_supplicant like attached picture, then go back to /system and press Mount R/O (upper right corner, so you leave everything exactly like it was) and reboot. Done. Enjoy AD-HOC!

Thanks for the patch, but before you get banned by some moderator, please remove your first attachment. It's a paid app/ WAREZ.

Root Explorer is paid. Don't post it.

Tested & working on sgs 2! Thx man!

I can see the ah hoc network established from my laptop now.. but when I try to connect, it stays in a state "Obtaining IP address" .. so cannot access internet anyway .. Is there any workaround? Thanks.

Thanks dude
excellent, previously i was using connectify to connect my phone to Laptop but the signal strength was so poor and also after few mins it is used to go down. Now got rid of the problem using this file.
Thanks again

+1 for me too.
P.S. just replaced the original file using Root Explorer.

hi,
the same here that varunmagical with VillainRom 2.4.2.
gs2 is able to find adhoc network but cannot obtain an IP.
very much thanks if you can find a solution...

Thanks a lot
it worked for me.

I replaced this file. This step is important:change the WPA to WEP encryption mode on PC. AD-hoc is ok using my SII I9100 mobile.Pls to try it. tks.

still not for me despite the wep ad-hoc network created from the mac.

what are the permissions to set?
is it important to switch back to Mount R/W ?
thank you

i have a tablet running android 2.3.3 rooted with superoneclick...i follow the instractions to copy paste the wpa_supplicant using root explorer.but when i open my wifi shows false and my table restarts.what i do wrong...i am lucky that i made copy of the original file

I´m actually able to see network but not to connect to it, any advise??

I take it this is not ICS / CM9 compatible ??

Galaxy S II
CF rooted stock 2.3.6
Working in free and WEP modes.
But there were problems with WinXP configuration.
(In wifi network first have myself to connect to created adhoc network, only then phone sees adhoc network)

Galaxy Note's WIFI VERY unstable after replacing wpa_suppliant.
I wanted to connect my galaxy note to my iPad's Mywi for wifi (ad hoc) connection.
Thus i did the following steps:
- root galaxy note using zergrush
- downloaded xda's replacement wpa_suppliant
- downloaded root explorer
- uploaded the replacement wpa_suppliant file to the phone and replaced the original one at /systems/bin
After this, my phone was able to connect to iPad's Mywi, BUT connection is VERY unstable and gets disconnected every 5-10mins. Also it takes really long to get it connected back, like about 10-15mins for it to try to get connected.
I've tried re-doing the WHOLE of the steps above, INCLUDING re-rooting my phone, but to no avail. My Wifi function was working perfectly fine prior to this.
Can some kind souls out there please advice me if I've done anything wrong in my steps? Or if there's any way to solve this (WITHOUT re-doing it back to the original)? thanks!

Hi! Recently I bought the Galaxy W equipped with GB 2.3.6 and yesterday I installed the latest january's firmware upgrade.
Did anybody try to install the modified wpa_supplicant into that device?
Thank you!
Antonio

Set permissions to wpa_supplicant like attached picture? Which permissions? Can you upload that pic again or just tell us what to mark, owner group others? read write execute? And from special permissions: Set UID, Set GID, Sticky?
By default at my stock wpa_supplicant permissions are set and marked like: Owner=mark at read, write and execute, Group=mark at read and execute,
Others=mark at read and execute. None of special permissions are marked.
Should it be the same for new copied wpa_supplicant or?
Thanks in advance...

Just one little question here. I hope someone takes time to answer it. I have been around reading about adhoc this and adhoc that. But what I wanna know if these methodes that enable adhoc functionality, allow 2 mobile devices to get connected to each other. I mean like between 2 SGSII not between a PC and a SGSII?
Like making one of the SGSIIs the center and the other client (or infrastructure or whatever it's called)?? Is this possible with all these adhoc enablers?

Can't turn Wi Fi on after using the file from OP.
Using ICS/CM9 Hydra rom.

How to connect to a Mobile HotSpot. 2ways.

Hi guys,
Since the mobile hot spot is an adhoc networks, so tablet cannot recognise it
directly.
So I found a instruction which is called can solve this problem.
We simply replace the original wpa_supplicant with the new one.
And put it in /System/Bin/.
I did the root and copy, but it still cannot find the adhoc hotspot for me.
So anyone have any idea?
Solution 1: solving it with the magic "wpa_supplicant"
Solution 2: changing the configuration of hotspot in my mobile to a normal wifi.
I'm waiting for anyone who can solve this.
Cheers
Winston

Hmm. I have a mytouch 4G and the A500 connects to the hotspot easily. No mods, rooting etc. needing.
Is this in relation to phones that are using less than carrier proposed methods for enabling hotspots?

Hi Neo,
According to what I have had known so far, it seems that google blocks this function,
so someone modified the wap_supplicant to enable the hotspot functionality.

Solution 2 depends on your specific phone and its implementation. My Droid for instance doesn't support infrastructure hotspot (outbound), so I had to use the "magic wpa_supplicant" approach. Other phones may support infrastructure mode, either directly or through a 3rd-party wifi tether app.
In terms of solution 1 - if you get the wpa_supplicant (apparently a new version has been posted for those of us w/ 3.1 update) you also need to reset the permissions on the file to match that on the original file (which I know you backed up, right? ); easiest way would be through Root Explorer and set Read: (Owner/Group/Others), Write (Owner only) and Execute (Owner/Group). I'm too lazy to remember what the Terminal Emulator chmod command would be
As a reminder to all who do choose to replace wpa_supplicant, keep a copy of the original file, you never know when Acer's going to require a specific original file for any future updates (wpa_supp wasn't needed for the 3.0.1 update but was for 3.1)

Yes I would say do not delete or move the old file just rename by adding old to end of file name. Its how I done it renamed did the update changed back. And now all is well again.I used the same replacement file from before. No need for a new. Version

Hi Vereyn,
Thanks a lot.
Could you please provide the link to download?
Frankly, I have tried all wpa_supplicant in this forume.
None of them works for me.
My version is Android 3.0.1
Acer ICONIA A5011, rather than A500.
Cheers

Soo... Which rock have you been hiding under exactly? This is pretty old news, and there are already a few threads detailing exactly what you need to do... Hell, there's one on the first page of this forum section!

Dear Floating,
Could you please send the link to me? or at least give me the title of that article which
you are talking about?
Because it disappeared again now >_<;

Again,
yes there are many ad hoc articles, but none of them work for me....

The links are in the forum, just scroll down a bit.
As for the articles not working... If they're not working for you, maybe you're doing something wrong or missing one of the steps?

How many with WiFi DHCP issues on Stock 3.1?

Hi,
Just wanted to find out how many people are having the WiFi disconnection/reconnection issue?
I'm thinking of delving deep into the frameworks to fix it, but I'm not sure if it is just a few devices (including mine) or more of a systematic problem.
Thanks

i had the same problem over the last few days. If factory reset didn't work it was a reflash. It works for me now but you never know when it's gonna crash out again.
currently running your 3.1 rooted rom and i'm in Sydney if that makes any difference.

had this issue with the leaked 3.1, Acer_A500_3.019.01_COM_GEN1. i'm using the new stock OTA Acer_A500_4.010.07_COM_GEN1 and haven't had that problem since i upgraded. i'm connecting my Iconia to a home router and a mobile hotspot and both work without problems.
A. if you're rooted, you can just delete dhcpcd-wlan0.lease located in /data/misc/dhcp and try reconnecting.
B. if not, you can try this:
1. Forget the connection
2. Reconnect to the hotspot, this time using Static IP instead of DHCP.
3. Assign a valid IP Address and connect.
i always do option B when i was having the issue.
hope this helps.

Just delete this file in term or root explorer whenever the issue occurs.
/data/misc/dhcp/dhcpcd-wlan0.lease

[Q] issues after ROOT, please help/guide me

Last night I decided to root my Nook Simple Touch, so I did the following:
1. upgrade to last official firmware (manual) - 1.2.1
2. root using this method
2a. problem with backup, so I started again, no backup.
-ROOT SUCCESSFUL, but no internet access (Connected, but no internet)
I tried rebooting, enable/disable wifi, change encryption, nothing worked
3. full factory reset - still no internet access
This morning, internet fixed by itself, so I decided to root again (remember that I made a factory restore last time):
1. root (like before)
1a. - backup went fine, it took long, but it finished
1b. - I could not find any backup on my SD, only a 62.9MB partition (free 41.3MB) ... so I assume that the card was partitioned and somewhere, the backup is written ... but how to copy it into my PC to keep it safe?
2. again, no internet access (Connected, but no internet)
Short version:
-after root it seem that I cannot access internet, what should I do?
-how to retrieve the backup from SD ? (as I said, I can see only a small partition, nothing more)
Thank you very much.
EDIT:
-I managed to find backup partition and save the backup file on my HDD using this partition mounting method
-Internet problem still remains...

I'm guessing that your internet problems and rooting might not be related. Have you tried things like resetting your router, using other wireless devices, etc? Maybe also try to use a different wireless connection somewhere too?
In my limited understanding, rooting shouldn't risk breaking wifi - at least before we get onto kernel and stuff like that.

And you were right ... from some reason, upgrading from 1.2.0 to 1.2.1 made things a little incompatible. But I had a lot of luck (I cannot tell that I know what I was doing), but now I can connect to internet.
