So, what can I check, to see why it's doing it? I don't see anything in the logs on the router that suggest it's doing anything. I am connecting to a VPN on there, through Cisco AnyConnect. I've seen various VPN's pop up on forums in the past when troubleshooting (other) issues, could that be it? Any tips greatly appreciated.

Yeah, I'd disable the VPN and see if it behaves the same way. That's show if it was a VPN issue or some other issue with the laptop.


Also, make sure you're on the latest router firmware.

Yeah, so, weirdly it's not the vpn. I've got the latest firmware, and even tried changing the router before I narrowed it down to the laptop. It's super odd, like you can see, the SECOND it disconnects the Internet speed returns to normal.

Make sure you're using the very latest WiFi drivers for the laptop. Get the drivers directly from the network card site rather than the laptop site. Sometimes the laptop site will have very old drivers.



If that doesn't help I'd try booting from a free Linux OS on a USB stick and see if the same behavior continued or not. That'd determine if your issue is with your main OS install or with the hardware itself.
