Internet strange behaviour!

Hi,

I have wirelles in my house.That one is connected with my PC via wire.Now after leving pc on all day and returnig home and trying to browse internet i couldnt do it.So i run troubleshooter and he couldnt identify problem so I decided to restart pc.After restart internet worked for few minutest and then sudenely stops.I restart wirelles.and problems stays.Scaned pc and he is clean.I take my mobile phone and coonect to wirelles and i try to brows internet.Guess what it works perfect!I can watch youtube on my phone and on my pc it wont open google for start.Then it take my laptop(Wrting from it now),and first thing i do is go and brows internet and i tworks.So what hell ig oing on??I have Win 7 64 PRo and NIS2012.I have also tryed to stop all NIS protections and i tryed again to use internet but stil same problem.MOzila and IE9 are not working.I also forgot to mention that when i restart PC and use that time gap while iE is still working and lounc small app that i use often to listen internet radio it will work.you can listen radio even if after that time IE cant open anything and when network troubleshooter is telling me that there is problem.but if i exit that app and try to run it again it wont work..
