I’m using Chrome, Windows 7, and from time to time my internet stops working. When that happens, I open Firefox and IE, but still no internet. It only starts working after I restart the computer. The odd thing is that my mom uses a laptop, and she’s having the same exact problem. We recently had our cable provider install a new cable modem, but the problem still persists. I also reset the router, but to no avail. My Mom’s laptop also has Windows 7, McAfee Antivirus Plus, and we’re both sharing a router. Does someone have any suggestions? Any help would be great!

You may want to have your cable provider to a line-check to make sure you have a strong signal. If two separate computers are experiencing the same issue, that is most likely your common denominator. Another question is how are the computers connecting to your router: wired or wireless? If wireless, are you sure you don't have some interference issues happening?

One computer is wired and the other wireless. The signal is strong. I can still how many Mbs is being transferred. And nothing wrong with the "Activity." Still transmission, but no internet till I restart.

try this network sharing center (right click your internet icon)/manage network connections/right click your network icon/properties/power management/clear box that says"allow computer turn off this device to save power"/ ok, this option when is check it turn off your network adapter after some time and you dont have acces to the internet even if you are coneccted so clear this box and I hope it works good luck.......any help is well appreciated, it all depends on who needs it. mark as answer if it help.

Thanks for the reply aztecamex. I applied the changes last night, but still experiencing same problem this morning. Anyone else have any suggestions?
