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.
Does anyone have any idea what problem could be? I have a 7510 32gb Tab.
