"my computer (only 1 computer ,a gaming desktop) has problems with internet (WiFi), I have tried many network adapters (Internal PCIe, USB, etc), but no matter what the internet is unstable, its not jumping off but its impossible to play online games because of the spikes, Runniing speedtest shows same spikes happen regularly, it's been reinstalled many times and has been tested with different drivers, best result is a foldable Android tablet connected as a USB network dongle (which is connected to wifi) but even then its still unstable, any ideas?
I tried increasing the CPU voltage and updating the BIOS just in case but it didn't do anything so I just put the CPU voltage back down"
Does the motherboard control network somewhere? even for USB devices?
