Ok, I have a rooted, wifi only Galaxy Tab. In an attmept to enable the ability to use wireless tether with my Epic 4G, I folloawed a video step by step on how to replace the wpa_supplicant file. Now, not only am I unable to connect with the phone, I cant connect on my wifi either!. It says "error" after trying to connect. Anyone know how to fix this? I'm dead in the water :-(
