I just bought a new laptop yesterday. it came preinstalled with windows 8.1. To be specific the brand is acer aspire e5-411-c313. My problem here is that whenever i conncet to the wifi, after 20 minutes it suddenly disconnects and when i turn it on again my laptop says there are no networks found. Can somebody please help me? I'm really having a hard time figuring this out. I downloaded all the updated drivers but to no luck. I even tried to uninstall the broadcom driver and install it back again but still it wouldn't fix the wifi. It goes back to normal once i restart my laptop but then again after 20 minutes it disconnects and i cant search my own or even my neigbours wifi. Hoping for all of your responses.
