I have just installed a very nice new router called Asus RT-N66U.
One of the main features is the ability to have separate WiFi networks on 2.4Ghz & 5GHz.
Everything was going well, until I tried to connect my iPod Touch to the 2.4Ghz network. It could not see the 5GHz network unfortunately.
The iPod Touch could see the 2.4GHz network, but would only connect about 5% of the time. The trick to make it work was to login to the routers settings and change ‘Channel bandwidth’ to be 20 MHz, rather than the default 20/40Mhz.
After that it connected immediately.
