Problems with WiFi

Posted on Petri but just thought might be worth giving it a shot here. Suddenly my laptop connected to my home WiFi stopped displaying websites. The thing is I can still ping both external IPs and urls. I tried system restore in case some update affected my NIC, deleted temporary internet files, reset my AP to factory and reconfigured, enabled WiFi on my router and tested with that to no avail, updated the driver from manufacturer's web site, scanned the laptop with Malwarebytes, disabled the firewall and run in safe mode with networking. Finally I run Wireshark on the laptop and I can see DNS traffic resolving IP but then the server sends RST,ACK for whatever reason. However, I noticed that when the browser connects to a website in it's status bar I can see some transfers going on but then it just hangs on waiting for page. Bizarely some websites manage to actually display some very small pieces of a page that I'm trying to visit like some titles, sometimes even some low-res graphics but that's rare and the page eventually dies. At the same time all works fine via wire. Any ideas?
