Every night, at some point, the Internet to my desktop and wife's laptop slows way, way down. Web pages plain do not load, although I continue to get Steam friend alerts, so I know there is a connection.
The weird part is, my iOS devices continue to work perfectly during this time.
The problem generally disappears in minutes with no action taken.
All devices are connected wirelessly to my Apple Airport Extreme which has a wired connection to my U-Verse modem/router (whose wireless connection is disabled). This setup has worked fine for over a year.
Any help would be greatly appreciated!
