Hello! I've recently discovered my internet speeds on my Asrock Z170 Extreme4 are extremely slow, I'm hitting 83 Mbps every time I speed test ( it hits 80 and slowly reaches 83.9 when using speed test), when I should be getting 300. I know this is not my LAN cable or network as I have tried this LAN cable in my brother's PC ( Which is an Identical build to mine ) and he is getting the correct speeds (300-350) as well as other computers using LAN and WiFi (5Ghz) also reaching these speeds. I have tried resetting my PC, switching BIOS, changing drivers, resetting the router, changing network settings and trying to look for any LAN related settings in the BIOS but nothing has worked. If anyone has a solution to this problem it would be greatly appreciated! I have ordered a NIC in the meantime ( TP-LINK TG-3269 ) but I would prefer using the inbuilt Intel I219-V. Thanks.
