Random ping/latency spikes and concern about failing equipment outside of house
Recently, my internet has developed random ping/latency spikes that are resulting in average pings of 20-30ms to spike up to 120-150ms every few moments. This is noticable in games and when I run a ping test to 18.104.22.168. I have run through all of the standard troubleshooting methods, including restarting/resetting my router, cable modem, checking/tightening connections, and ensuring no faulty cable issues. I have run ping tests directly from my computer to the router to verify that no issues are occuring between that connection--everything checks out OK. The cable connection coming into the house appears fine--cables are tight, no rust, etc. However, near the property, the connection box is a cause for concern because a section is hanging open and an extensive amount of cable is wrapped around the outside of the box. Also to note, I am on a wired connection and the signal strength on the modem appears to be within acceptable ranges. I believe it's not unreasonable to suspect that an issue might be coming from some faulty equipment there.
Is it possible to request Comcast to service this equipment?
