Guys, I really need help on this. I am stuck in Afghanistan for another 1/2 a year. We only have wireless Internet, no wired. I want to be able to connect my tablet and cell phone to the network, but there are a couple of issues. First, the signal is very weak in my room, so I bought a high gain wireless usb antenna for my laptop that made things better. Second, the ISP requires a login. You can't log in with multiple devices and it takes over 5-10 minutes to drop a login (you can't log off). Even if the log-outs were shorter I couldn't connect with my phone/tablet anyway because of the weak signal.
The wireless adapter I bought has SoftAP for Windows and I can also share the connection on Windows from wireless to wireless using Connectify. The issues with Windows are that I need to disable the firewall for it all to work (no way around it) and I keep getting logged out or the connection will go stale after awhile. The network works extremely well in Linux Mint 14. The connection does not drop, even overnight. The problem is that I can't find a way to share my wireless connection with other wireless devices. There is so much information on how to share an ethernet connection over wireless with Ubuntu/Mint, but nothing on sharing a wireless connection over wireless. This can be done quite easily in Windows for almost 2 years now. I just can't believe that this can't be done on Linux. I'm discouraged that no one has replied to my post.
