Around October last year I suddenly started getting intermittent high ping and packet loss (10-30%) on wifi and ethernet which became very noticeable during work calls and gaming. I used both sky and BT over my the last months I lived in that rural 70mbps max area but swapping didn’t seem to effect anything. I initially believed it was caused by a connection point and cables which I replaced several times to no avail. I contacted my internet provider and had several engineers sent out but they couldn’t find anything wrong with the physical connection and just kept dismissing the case aside from the occasional router change. (Including some of my own which I just bought online) I didn’t really believe them at the time because the same issues were present on multiple devices in the house and trace routes seemed to indicate there were issues at the neighbourhood box so I just brushed it off until I moved. (My new place has 1gbps on both wifi and LAN) However as soon as I moved to my new place my PC started having booting issues where it wouldn’t load into windows and would remain awake but on a blank screen until I did a boot override using my ssd from BIOS. However, stranger still is that my connection was working perfectly on all fronts for about 5 days with no issues whatsoever before it suddenly started experiencing all the same problems again. (I’m currently using Tp link router with virgin wifi gigabit internet) Every other device I’ve tested, including my phone, exhibits none of the same issues as my pc.

My Ethernet is controlled through the motherboard by a Realtek PCIe GbE family controller and my wifi by a 802.11n wireless LAN card, with neither showing any problems I’m able to see. I’ve tried updating and reinstalling every driver in my pc, tried checking for corrupt files, updated to the latest BIOS on a gigabyte B550 gaming x V2 motherboard, checked and redone every connection on the board (GeForce RTX 3060, wifi card, ddr4 16gb ram, AMD Ryzen 5 5600x, 1TB ssd + 500gb hdd etc), looked through device manager and event viewer for anything obvious, made an entirely new profile to see if the connection changed, used a USB to Ethernet adapter to check every USB port I could on the motherboard, (same issues across all) reset the network and the firewall several times and constantly run ping plotter and trace routes. The packet loss on wired connections has gotten significantly worse to where it averages around 60-90% with low ping, however the wifi seems to have much less packet loss but very high ping even though I’m setup directly next to my router. My only guess at this point is that some chip on the motherboard is fried but I’m at a complete loss as nothing has worked and it only seems to be getting worse. I’m not sure what to do from this point aside from take everything out and replace it so any advice or help is appreciated.
