Hi, After upgrading to Windows 8.1 my download speeds are maxing out around 4mbps.
I have a 120mbps connection and all other machines on my network are achieving around 70mbps.
I have reinstalled the correct wifi and lan drivers several times which solves the problem but only until a system restart or a switch between wifi and wired lan, at which point speeds return to 4mbps.
I have trawled through countless forums on microsoft and lenovo websites.
There doesnt seem to be any consensus as to the whether this a Broadcom, Realtek or Windows problem.
Please help, I am very frustrated with this situation.
