My ethernet will disconnect randomly while i'm doing anything on it. When the first time it disconnect, I need to press the "scan for hardware changes" to fix it, disabling and enabling the network adapter results in a code 10(device cannot start). Then, windows install a new adapter named "Realtek PCIe GBE Family Controller #2". After this if it disconnect again, it can be fixed by disabling and enabling it. Also, when playing a flash game, the adapter disconnect very often, about every few minutes compared to a few hours if not. When watching a video on youtube, the same thing happens but clicking another video on the sidebar cause it to disconnect immediately. When starting any online games, it also cause the ethernet to disconnect. But this time, the light on my router goes off as soon as the game loads for ~5 seconds before coming back on (note that when not playing a game and it disconnect, the router light never goes off), but i still can't use the internet (windows shows a red x on the network logo). Sometimes i would have to reset the ethernet adapter 3~4 times before it works again. Using ASUS P7P55D-E Pro, and it searching on google it seems that quite a number of people using an asus mobo gets random ethernet disconnect. I've tried reinstalling the drivers, used a different router, changed settings in the adapter (switched the settings one by one). This started happening about 1 week ago, and it seems to be getting worse, the frequency of the disconnect is getting higher. It seems that when it disconnect while i'm loading a page, it will keep loading for minutes until i disable the adapter, which it then displays an error.
