"Acer Aspire v5-571P - Replace the network card?" için yanıtI have the same problem with my Acer v3-571g. In my case the network card deactivates itself even when im connected via ethernet cable (at first i thought maybe its just a wifi problem). And it's so frustrating because I have to restart in order to make it work again... I tried a lot of solutions, seems nothing is working. Did you manage to fix your problem?
