Has anyone noticed Safari issues when browsing on a 5GHZ band? I have a turbo connection with Time Warner + DIR-825 router, but a lot of webpages get hung out (do not properly load) when I am browsing on my iPad2.. I just got it yesterday so I haven't had a lot of time to use it, or really compare it that much with 2.4GhZ. Any reason a 5ghZ would be slower on iPad?
