RandomR
Tuning in

Hey,

I'm getting a frequent observable packet loss spikes throughout the day starting a few days ago. See the following quality monitor for reference:

Can someone take a look and see if anything is wrong with my stats etc:

What actual issues are you experiencing on your connection?  Also, are they on just wifi connections or also on ethernet cable connections too?

Those spikes are remarkably cyclical at every four hours.  Do you have anything connecting - say on a timer -  every 4h?

Hi I see some post rs errors on 2 channels, as well as quite a few t3 timeouts on all channels but channel 1.

What does your netlog say? Do you have any t4 timeouts and has this been happening for a while? or just one day. Have you any time sensitive packets like gaming or streaming or video calls if not you probably won't notice it. Though packet loss is a sign of network problems with the timeouts post rs errors and t3 timeouts. Someone from vm should contact you on here soon good luck.
