Tower Plus EBT2250, will not connect to internet (ethernet) when going to sleep for short periods
I have been having this issue from when i bought the computer, when my computer goes to sleep for short periods, when it wakes up, it will not connect to the internet, i need to disconnect my ethernet cable, then connect it and its fine. I have noticed when it goes to sleep for extended periods, its fine. I have tried all kinds of things, anyone have a solution?
