WiFi dropouts every few minutes/hours and router resets every few hours.

[Jpt44]

Hi,

For MONTHS/YEARS, my virgin media router has been restarting itself every few hours, causing for the WiFi to be down for atleast 3-4 minutes at a time. This has been happening for SOO long that I cannot even remember when it started. When looking at the network logs, there are many 'warning' codes and then the router decides to restart.

Another issue that has quite recently arose within the past week or so, the WiFi will disconnect my computer, then reconnect me a few seconds later. This has been happening every few minutes for the past few days and makes using the connection unbearable. Also, the router is capping my computer to 80mbps and after changing the MAC address of my computer (so that it detects it as a different device), it will uncap and let me receive the normal 300-500 mbps.

Overall, there are just many issues which have been happening and I really do need a resolution to these problems as there are just WAY too many.

The post linked here, seems to have also had the same issue and it has been resolved.

I will put the logs below here. The only thing that I can tell from these is that when it says 'REGISTRATION COMPLETE - Waiting for Operational status', these are the times that the router has reset itself. If anything else is needed, please let me know.
