I set the router up with different SSIDs on each channel, and hoped that I would be able to connect at 5GHz with my SGS2.
I can see both SSIDs with my iPad 1, and can connect to the 5GHz channel.
My SGS2 can only see and connect to the 2.4GHz channel, it cannot see the 5GHz SSID at all. Using the android app "WiFi Analyser" the SGS2 cannot see the 5GHz channel at all.
The SGS2 is running ICS
Baseband Version l9100XXLPS
Kernal Version 3.0.15-l9100XWLP7-CL340913 dpi@DELL134#3
Build Number IML74K.XWLP7
Does anybody know if there is a known issue with ICS and WiFi at 5GHz, the net seems to have a number of people having issues with locking up and rebooting and needing to remove the battery to restart since ICS was released, I have only had one reboot when enabling WiFi and that was while trying to get the 5GHz wireless to connect.
