On one laptop...Dell Latitude E6520, the Wi-Fi will just drop. I can go to networks and reconnect each time but it drops sporadically.

On a custom built pc with a Wi-Fi adapter, it does not drop at all, but after a reboot, Windows does not remember that network even though I checked the Remember radio button.

Not a real bad deal, but it is annoying. The Dell laptop has the Dell 1520 n card and the other pc had a TP Link TL-WN725N.
