I have used a Cisco Valet Plus wifi router for several years. A few days ago I could not connect to most websites. I could connect to gmail, to Facebook and to Linked-in. This was true on my desktop which has a hardwire connection from the modem through the router to the computer, and to my iPad. When I eliminated the Cisco router and just went from the modem to the desktop all was o.k. When I would reboot the modem and router the first attempt to connect to another website connection worked - but after that not.
I am thinking this could not be a desktop computer issue since it also affected the iPad. At present I am just connecting with my desktop as the wifi is bypassed so can't connect via the iPad.
Any computer experts here have a clue?
