I'm having trouble with my ethernet connection. My modem and router are both working properly. I say this because my wife has no trouble accessing the internet on her laptop ( the device that I'm typing on right now), nor do we have an issue with either of our android phones. So I think my wireless router is ok. Also, I've hooked up her laptop directly to the modem via a wired connection and no problem there either. The issue I have is with my PC, after boot up, I get the "yellow triangle" saying "no internet access." I open the Network and Sharing Center and let Windows 7 diagnose the problem and I get one of two messages,
#1) The connection between your access point, router, or cable modem and the Internet is broken.
#2) The DNS server isn't responding.
So, having read several posts on this site from folks having similar problems, I have downloaded Malwarebytes and Kapersky TDSSKiller and ran them both. Neither of them detected an issue. I even thought that I may have been being paranoid about having a virus causing the problem so I bought a 20 dollar ethernet card and installed it (thinking that my onboard Mobo port my have died) and still have the same issue.
I'm at a point now where I'm not sure what to do. I know I'm probably overthinking it and making it worse than it is, thus making the simple solution elude me.
Anyway, for those who read this and have a suggestion. Thank you.
You said the laptop works over wire, but you only tested that when connected directly to the modem. Try the laptop connected to the *router* over wire so we can see if this affects EVERY wired device to the router, or only Gavin-PC (in fact, use the same cable and same port on the router too).
Ok, I unplugged the cable from my PC and I'm running on the same one to the laptop now. So it seems that the router isn't the issue, and the ethernet cable isn't the culprit either. I did forget to mention that I tried all four ports on the router in my original post, all with the same result.
Just want to say also, thanks a ton for the help man. I've been fighting this for a couple of days and my brain is a bit fried.
Just turned on my PC to beat my head against the keyboard some more and for whatever reason, I have internet access again. So on the positive side, I have access for now. On the other hand, it looks like I have an intermittent problem... and those are always a pain to troubleshoot.
