Thinkpad T430s - no network :S

RFD,

Hope you can help me troubleshoot this.

I've had this machine for almost 6 maybe 7 years and no issues. Yesterday evening the T430s (Win 10 Pro) resumed from sleep mode and had no network connectivity.

It is connected via WiFi and it does receive an IP but it is unable to get out of the home LAN. It say DNS failure.

Fair to point it, none of my other devices, notebooks, RING, lapotps, TVs etc have any issues. Safe to say, the issue is localized with the machine.

Troubleshooting steps I've taken include:

Laptop
- Reboot the machine at least 3-4 times
- Switched off/on and Disable from device manager
- Delete the existing home WiFi network and have the laptop re-acquire it
- As mentioned, I do acquire an IP but pings to anything outside the home LAN fail (General Failure)
- Pings to inside the same home LAN are OK
- Pings to the DG (default gateway) are OK
- Even tried WIRED blue cable plug in DIRECT - no go i.e an IP is granted but cannot get out

Wi-Fi router (Linksys)
- Rebooted the router
- Rebooted the incoming feed's cable modem box

Another WiFi source
- Using my iPhone's tethering, I setup another WiFi network and had the T430s connect to it
- Again, yes it is connected and an IP is granted but it cannot get out

Pls help.
Please thank me if you find this helpful

RFD,

Problem solved.

I use a VPN app called - Windscribe - you might have heard of it? Anyway long story short, it had added a line to my Windows hosts file. I deleted said line, uninstalled the app and rebooted PC.

All is well!

I have written to their customer support informing them of such.

Weird because in all the months with Windscribe - I never had any problem.

Thanks.

Wow. Wondering how did you find out it was the hosts file? Did you end up trying sfc /scannow?
