Hi,
When I switched my pc on yesterday I had no Internet connection. WiFi is working fine but the connection between the router and pc isn't being recognised. I've tried plugging the cable into a different port on the router with no luck. I've tried a different ethernet cable - still no luck. In Device Manager, Network adapters, it says the device is working properly.
Any suggestions as to what to do?
We had a lot of thunderstorms could that have caused a power surge or something???
Also, whilst switching the pc off,unplugging andleaving it, the monitor has failed too, so now I can only get it on bt pressing F8 during the boot up. 🤔😬😭

Network routers, modems and such are susceptible to power surges. It is possible that all or some of the ports on the router were damaged. I have seen it happen. Wireless works fine, but, all the ports dead.

Can you connect directly to the modem? If you can and if you get a good connection then you'll know that the router ports are bad. If you don't get a connection then the problem is in the computer.

Judging by a problem with the monitor I would bet the problem is the computer.

Thanks. I have 4 ports on my router and one of them connects the Powerline adapter for my Youview box. That hasn't been affected and it works even if I plug it into one of the other ports which don't work for my pc ethernet cable. the LED light for the Powerline cable is constant whereas whichever port I use for the pc's cable flashes on and off. that indicates to me that the ports are ok.
I haven't tried connecting directly to the modem as I'm not sure what you mean.

Hi Mokies,

Please confirm that this is a Win7 machine.

....the monitor has failed too, so now I can only get it on bt pressing F8 during the boot up
When you hit F8 there should be an option to boot using "Last Known Good Configuration" - give this a try.

Yes it is and I can report that the monitor is now working ok.

Hi again,

Good to hear that your monitor is now behaving itself.
I assume that you still cannot use an ethernet cable but wireless is OK ?

Go back to Device Manager.
Make an exact note of the device listed for your ethernet connection.
We may need this later.

Now right click on it > Update driver.
[ you will need to be connected to the internet ]

If still no good - Device Manager again > right click the device > Uninstall
Re-boot the machine.
Windows should find "New hardware" and re-install the drivers.
Try the ethernet cable again.

*** What is the exact make and model of your machine please? ***
