I have a Windows 7 PC that had been happily connected (by Ethernet cable) to a fibre modem/router for about a year. This evening, I turned it on: no internet connection.
After some tinkering, a couple of things stand out to me as particularly strange:
I've tried various things that seemed obvious:
What could possibly have gone wrong? And how can I fix it?!
Many thanks for any help.
After some tinkering, a couple of things stand out to me as particularly strange:
- The PC connects fine to the internet via Ethernet cable to a second router, which in turn is connected to the fibre modem/router. (This setup exists because the fibre modem/router doesn't have WiFi itself, the second router does).
- My laptop connects to the internet fine over the direct Ethernet connection to the fibre modem/router (which the PC can't).
I've tried various things that seemed obvious:
- Ran Windows network troubleshooter.
- Rebooted the modem/router.
- Rebooted the PC.
- Checked basic connection properties (auto IP address, auto DNS server address).
- Reinstalled NIC drivers.
- Flushed the DNS cache.
- Winsock reset.
- Ran virus scans (Malwarebytes and MS Security Essentials).
What could possibly have gone wrong? And how can I fix it?!
Many thanks for any help.
