Does anyone have any idea what problem could be? I have a 7510 32gb Tab.
I used to be able to connect to my 5ghz wifi network without a problem. It stopped working recently when I flashed one of the CM9 ROMs. I thought it had something to do with the ROM but it was working on earlier CM9 builds. I flashed back to Task650's v14.1 ROM where it used to work fine but I still can't connect. It sees the network but when I click connect it doesn't do anything. I haven't made any changes on my router and I can connect to my 2.4ghz network fine. I have a Linksys E3200 router with the 5ghz network setup on channel 36, 40mhz channel width and WPA2 personal security. I've tried changing all the settings on the router but i still can't connect. I did Odin back to stock last week because I was getting a lot of reboots on the CM9 ROM I was running. After that I flashed CWM and then flashed the latest CM9 ROM. It seems like the trouble connecting to my 5ghz network started around that same time.
