Question

Router not detecting Wired Connection

Mar 31, 2018 8:11AM PDT

Have an interesting issue - I have a router netgear R6250, and a PC with a wired connection to it. Recently, my wireless printer stopped working, and after some troubleshooting, I realized that it was because my router doesn't see my wired PC on the network. It sees all my wireless devices, and my other wired PC, but not this one.

I have internet access on the PC, which is the strange part. I have tried resetting the router, rolling back windows 10 updates, WinSockFix, making sure network discovery was on and the associated services are running, created a limited access windows 10 account and trying it from there - nothing.

Any ideas? I was working previously but only in the last month has it stopped - hard to peg down as the internet still works fine.

How was this set up and how far from it is the router?

I'm going to say that, if you have internet access through that router, your wired connection is fine as long as your PC doesn't also have a wireless network interface device as well as a wired one. One easy way to see if you can connect to the printer is to try and ping it's IP address. I always use a static address with network printers so that's why I asked how was this set up. If your printer gets an address from the router, troubleshooting gets more complicated. You'd need to see if the printer has an LCD screen where you can find its current address so you could attempt to ping it. If by any chance your router is in a basement area and the printer upstairs, I'd look for that to be related to the problem and a bit more information about the setup and distance would be helpful.

Hello,

Printer gets an IP assigned by the router, as did everything that was connected to it - for some reason the same isn't happening for the 2nd PC in my office.

I have tried to connect a laptop to the same cable the PC is connected and I get the same problem - gets internet but no local access to any other device connected. Its about 65 feet from the router.

I cant ping any device on the network from the PC

When we call on such

We carry in cables and another router to see where the problem is. This can be very rough on new networkers since they don't know the easy troubleshooting ways. That is, swap out what you suspect.

I take it you tried a few things, power off and on, etc.

Thanks everyone for the help - It was a cable issue. Strange that it would still carry internet. Would ahve never suspected.

I understand that having only the transmit and receive pairs properly functioning is OK in limited circumstances such as 10 base T or maybe 100 base but all 4 pairs are needed for Cat5e and up. I could be wrong about that but I'm going to guess that your transmit and receive pairs were proper something was amiss with one of the other two pairs. It would be easy to test this with an ohmmeter if you had one.
