when I was using windows 8 it was Ok with my NetGear P2TV 3000 >>>> when I update to 8.1 ... It stopped working ( in both situation if i use old drivers of wireless and WiDi or the latest) .... but i'm not facing any problem if i disconnect my WLAN internet connection ...... so I can use only one connection ( WiDi or Wireless internet ) But not both !!!!!!
I didn't try to update Intel graphic card because I'll face screen monitor brightness problem with win8 or win8.1 ... i have to use old driver !!!!!!
It seems that there are a lot of conflicts between hardware and windows 8 and 8.1 because I lost the ability to use two fingers touch on the tap as right click after I updated to win8.1
But the other major problem I found in WiDi technology is that when i open any 3D game while i'm using WiDi i'll hear only the sound from tv but what appears is only damaged picture ( colored dotted lines) ...... It seems like that the WiDi connection speed is very low and can't handle gaming ...because If I use cable to connect to TV I can run any game in any resolution I want .......
Please i need solutions .... at least for solving connecting to TV through WiDi without need to disconnect Internet WLAN Connection
