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.

Can you iPhone create a ad-hoc? That's maybe why you don't see.

ad hoc
I use pdanet to turn my iphone into a hotspot. I was told by someone that pdanet creates an ad-hoc and thats how devices connect to it. It works on other phones , IPads, notebooks, the only device that doesnt see my iphone as a hotspot is my Galaxy tab. I have a friend who has the vibrant and when she turns on her tethering app my galaxy tab sees it and connects. Basically im stumped

I was wondering if you kown, can the Tab create a ad-hoc? I would like to use the Tab to create a ad-hoc network, other devices can join it. It looks like its "Mobile AP" is doing it. But without SIM card, it does not active. Same as you, I don't have data plan for it, even no SIM card inserted. Thank you.

I don't have SIM card inserted. I don't see the network SSID from my laptop, so I think it's not enabled because there is no SIM card.

If you are trying to use your Apple iPhone with the unlimited plan to tether to the Tab, try using MyWi in either Cydia or ROCK. It works great as this is what I use since my iPhone plan is unlimited and it sees the new Adhoc connection with this update above.
