I have a 2013 Toshiba Qosmio laptop. Had it for three and a half years. Up until 3 weeks ago the wifi adapter in it (atheros ar956x) worked great! I have 40 down and 5 up internet.
Last month I went on a trip and used my phone to usb tether since that was the only internet I had there. Ever since I've come back from the trip though my internet has been extremely slow! I get maybe between 1 to 3 Mbps down and same up.
Tried uninstalling and reinstalling the WLAN driver. I tried disabling and reenabling the adapter. I unplugged and plugged back in the router. I've tried everything I can think of but the performance is still the same.
So I'm wondering, what is the problem? I have windows 8.1 64 bit btw. Could the adapter have been damaged going through x-rays at the airport or just natural wear and tear? Could usb tethering the phone have had an adverse effect on the speed? What can I do? I need to use/keep this laptop for at least another year before I upgrade. Thank you very much everyone.
Also forgot to mention a couple weeks ago when I got back but before I hooked it back up I took my laptop into a computer place to get it cleaned/dusted out. Could that have affected anything? If the card is bad, what is the best usb 3.0 wifi adapter I can get that'll hopefully use as little of resources (cpu/ram/etc) as possible? Thanks.
