Network / Sharing :: Win 8 / 8.1 - Timeout Too Often / Page Cannot Be Displayed

I have MSI laptop 17.3" Core i7-3630QM/16GB DDR3/NV GTX 675MX, 4GB, Windows 8.1 upgraded to from win 8. Wifi: Intel Centurino Wireless N2230

Not only on Windows 8.1 but on Windows 8 as well ever since I am on the new system, I get too many times 'This page cannot be displayed'. This happens like a page timeout where it takes it longer to load than allowed..

I have been on Ethernet 50 mbps and there seems to be no problem - I can load 10 tabs at a time and they will load. The problem happens when with wi fi modem and supposedly no one else uses the connection, with speedtest I get 17 mbps download, 8 ms ping, 10 upload or smth.

At first I thought it's specific sites doing it but heck it can happen anywhere, forums with just background images, this is where it mostly happens btw, not google images or places with just many images, even forums with simple UI interface, emails.

Is this a lan card issue? Hardly, Ethernet connection is good but maybe it is separate. the modem? If I try smartphone with the wifi which is usually disconnected to not eat the traffic and connectivity, it works fine but maybe Android works too differently. With the notebook I've been having this for 1 year and getting annoying, haven't changed the place yet but 17 mbps should be good enough

In few games, I may lag but this happens rarely in most cases such speed is fine and yet for forums and such it can't load a darn page until I refresh 2-3-5 times... (sometimes without the pictures). This forum loads fine but others and sometimes mail services do not.
