I have the same problem in 2 different PCs: if I boot in safe mode with network only I have the full ISP bandwith (650Mbs for LAN, 150Mbs wi-fi), but in normal mode I have around half when wired and only 20Mbs on wifi
I had already updated all the possible drivers, without success...
I have Norton 360 on the LAN pc and Office Scan on the wifi pc. Windows firewall is disable on both
I've tried to disable the Norton but nothing changed. I can't disable office scan.
Do you have any idea or do you know any tool that can help me in understanding what software is causing the problem?
Not sure if this is the right place for this request: please point me to the correct one in case is wrong
thanks in advance for your help!
