I just updated to iOS 4.3 (from 4.2.1) on my first generation iPad. I have a Time Capsule running a 2.4 GHz network and a Linksys E2000 setup as a network bridge (DHCP and NAT disabled) running a 5.0 GHz network. I live near a college and need the 5.0 GHz network because there are at least ten 2.4-based networks in the area.

Before the update to iOS 4.3 my iPad was able to connect and use the 5.0 GHz network without issue. Immediately after the update it reports it cannot connect to the network. My wife's iPad, still running 4.2.1, can connect to the 5.0 GHz network without issue. I have removed the WPA2 key and ran the network unsecure for a couple of minutes but that didn't resolve the issue. When I re-enabled WPA2 I also changed the Linksys to use 2.4 GHz instead of 5.0 GHz; the iPad connected immediately. When I changed it back to 5.0 GHz the iPad immediately would no longer connect.

I am quite familiar with networks and, despite having two routers on the same network, they are configured properly and this setup has worked for months. Indeed, it still does work with my iMac and wife's iPad (running 4.2.1).

Is anyone else having difficulty using the 5.0 GHz spectrum after this OS update?

Thanks!

iMac (Late 2009), Core i5 2.66 GHz, 4 GB RAM, Mac OS X (10.6.6), 16 GB iPhone 4, 16 GB iPad (1st Gen.), Apple TV (1st Gen.)
