The message I get is: "The connection has timed out. The server at www.(name of site).com is taking too long to respond."
We had time warner and now have Verizon. I had the problem with both carriers.
My husband has no problems getting to any site he types in. We don't have anything blocked that we know of so we just have no clue what is going on with the computer.
Also, when I am surfing the web a lot, I will start having problems with more sites loading (such as those I normally have no problems with) and I end up having to reboot the computer.
