I have in my possession a G1 and a new Android tablet (the Kmart one, the Gentouch). The Gentouch uses wifi to access the internet; the G1 uses a T-Mobile cellular connection. Ideally, I'd like to somehow cause that G1 to emit a wifi access point, so that whenever the G1 and the Gentouch are in close proximity, the Gentouch can piggyback off the G1's internet connection and reach the internet itself. Assuming I am willing/able to root both devices if necessary, how would I accomplish such a task?

There are apps on the market that can do this on most rooted phone. Barnacle is pretty popular for this and people seem to like it. Actually the first review for the app is someone doing exactly what you want to do just with an Ipad. Just search for "barnacle wifi hotspot" on the Market, good luck.

    @Matthew Read: That's fair, absolutes are probably not appropriate when it comes to rooting. I'll change it to a more flexible, "most". Commented Dec 27, 2010 at 19:41

  • Problem: Android seems to have trouble connecting to Ad-Hoc networks, and the Barnacle supplies.... an ad-hoc network.

  • All of the wifi enabling apps that circumvent the carriers WAP service use adhoc.

For completeness, now I got the tablet to connect to adhoc:

wpa_supplicant.conf edit


#added ap_scan=2 so it scans all networks including ad-hoc
#this causes priorities to be ignored below.  
#it just goes through the networks one by one.  
# this can really slow things down.  
#I recommend putting a simple file like this with the ad-hoc network at the top
#on your sdcard and then just copy to /data/misc/wifi directory when needed. 
#I sure someone could write a script to backup current and swap in adhoc one.

#added my ad-hoc network.  
#wep_key0 only needed if you use wep.  "" if ascii / no "" if hex
#mode=1 needed to indicate ad-hoc

#normal access point network
   auth_alg=OPEN SHARED

  • It's a solution to make the previous solution work.. not sure what that would fall under. +1 for the details. Commented Dec 28, 2010 at 14:08

  • I think its great you added it. I was actually going to ask what changes you made just for future reference. Commented Dec 28, 2010 at 15:29

I ran into the same problem with my archos tab not being able to see an adhoc wireless connection. I was able to effectively connect my unrooted archos (running 2.2) and my rooted droid (also on 2.2) via the bluetooth tether option of the "wireless tether for root" app. To be clear this allowed me to access the web on my tab through my phones 3g connection. I wasn't able to get it to work when the tab was on 2.1, but I had read about others that had.
