Hello,
I have an Aspire E1-571G with Windows 8.1x64 (clean install, no upgrade and so on) and I've been having issues with my broadcom wireless drivers ever since I installed it. The troubleshooter showed up that there is a problem with the default gateway but here's what really happens: I can stay connected to a wireless network but after random periods of time I just lose internet access (note that it doesn't show up in the connections page, everything looks perfectly fine there) and I have to reconnect to the wifi to regain it. I have tried on multiple wifi network and it does the same thing. It works fine if I use an ethernet cable but that just makes it more frustrating.
I have tried all the possible solutions I could find online like checking the power management settings, reinstalling the wifi card in safe mode, checking the priority of the wirelss connection, virtually anything. There is no hardware issue with it, it worked perfectly fine on Windows 7. I haven't been able to find wireless drivers for 8.1 and even though I have the latest drivers, it still doesn't work right. There are moments when I can keep my connection for more than 2-3 hours but there are times when it crashes every 5 minutes or so.
Does anybody have any idea how to fix this instead of waiting for the drivers to be updated ? I've seen that I'm not the only one with this issue and it's a bit common for e1-571g users. For example lenovo users had the same problem and the only fix was to install the default windows drivers but that doesn't work for me.
