Today my virgin fibre optic broadband got installed that is capable of 1100+mbps however wehn I use my cat6 flat ethernet cable to hook up my pc straight to the modem, using SamKnows Real Speed (https://samknows.com/realspeed/) it tells me that my pc maxes out at 155mbps. I have checked the network connections in control panel and it states that the speed of the ethernet cable is 1gbps so I do not understand why I'm limited to 155mbps
