david Posted January 23, 2010 Share Posted January 23, 2010 Every once and while, I will be surfing the web and my connection will drop. I get a yellow exclamation mark on my network icon. The only way to fix it is to do a power cycle on the router and modem and then reboot. Sometimes that will not work. I have tried a new router, still does it. Replaced the cable line, still does it. Bypassed the router, still does it. I have a SB5100 connected via ethernet. Is my modem supported on Windows 7 Ultimate x64? Link to comment Share on other sites More sharing options...
+allan MVC Posted January 24, 2010 MVC Share Posted January 24, 2010 (edited) It's either a problem with your ISP, your modem or your network card. Easiest way to better isolate the issue is to connect another computer to the same modem / router and see if the problem persists. The fact that it's intermittent certainly makes it harder to diagnose. Link to comment Share on other sites More sharing options...
