Investigate router, access point issues

Hi there guys

I suddenly can't connect to wifi, but the problem is solved when I use the cable, and connect my laptop directly to modem. surprisingly I checked and it seems I can connect with my tablet to wifi spot! I used recovery and system restore point, but it didn't help.

I really appreciate your help. :)

oh and yes in wireless mode, I can see different wifis, but when I click to connect, it tries "connecting" but fails as well.

Do you use MS Update in Autoupdate? looking to see if you are 'current'.

get make/model of your WiFI device (see device mgr),
find the version of the existing driver, then
see if you can find a newer version; install it if found.
