I've been googling the heck out of this. I updated to Windows 8.1 on my laptop a few weeks ago. Ever since, I can only hold a wifi connection for maybe 15-20 min max. Else it goes to a "limited" status where I have to disconnect and reconnect and then all is well again for another 15-20. This has happened at my home, at hotels, at my parents' place. I've been traveling a lot so I'm seeing it everywhere.
My Mac and iphone and other wireless devices at home are not having any issues with wifi connectivity.
Based on my searches, I verified that my driver is updated, I made sure that the power saver for network is unchecked. What else can I do? The MS website just keeps referring to the driver or your ISP. It's clearly not either of those.
Network adapter is Broadcom 802.11n
Thanks in advance!
