HP Pavilion 23 desktop with Windows 8 (recently new)
Comcast DOCCIS 3 compliant Xfinity modem delivers 50mbps directly connected but just 15 feet away drops away to almost 16mbps during the day, maybe 28mbps in the early early morning on the East Coast.
I am reading on another forum that speeds can be tweaked at the Windows Registry. Can this work for wireless speeds and in Windows 8?
That's not an OS issue. Wireless signals are hampered by physical materials (walls, that sort of thing), that the OS cannot fix. If you're looking to boost a signal, a wireless repeater is what you would need.
