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.
