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.
