Samsung Tab and Ad-Hoc wifi Networks...?
I purchased a Samsung Galaxy tablet this weekend with out a 3G data plan as my idea was to just tether it to my cell phone where I have an unlimited data plan. There are several apps that will turn your phone into a wifi hot spot but all of them create an AD-HOC wifi network. Much to my surprise, by default, the Samsung Galaxy Tab will not see or allow you to connect to AD-HOC wifi networks. I took me some time to figure out how to get around this. I figured if I posted the information it might same someone else the same problems I had:
1. ROOT TABLET (This is a MUST)
2. MOUNT /system as RW - #mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
3. MAKE A BACKUP OF /system/bin/wpa_supplicant
4. REPLACE wpa_supplicant WITH VERSION I HAVE ATTACHED TO POST
5. MOUNT /system as RO - #mount -o ro,remount -t yaffs2 /dev/block/mtdblock3 /system
6. TURN wifi OFF and BACK ON.
Once you complete step 6 if there is a AD-HOC network in range it will show up as ssid(adhoc)
in the available network list. Once you see the AD-HOC network you will be able to configure it and connect to it like you would any other wireless network.
