said by Dominion:How many samples did you include in that plot? It doesn't look like you have any packet loss if that's actually showing the full 40 minutes.
After reading the guide for Pingplotter I realized that I accidentally left it on the default option for graphing so it only graphed the last 20 results. That chart is useless as it only shows a small fraction of the time I ran the test unfortunately. However, the slow upload has returned this afternoon and I am running a thorough pingplotter test that will continue for many hours. I don't think I will find significant packetloss but at least I will know for sure.
said by Hard Harry7:Looks like there is a 5% packet loss between hop 1 and 2. I notice you have a Cellspot router, any relation to performance problems and making/receiving cellular calls?
Not that I have noticed, wifi calling has been very stable on my home network. I have only had 6 dropped calls in the lifetime of the router and all of those are easily attributable to the person on the other side. Occasionally when I check my phone I will notice that the "T-Mobile Wifi" indicator that WiFi calling is ready is missing but if I turn off and on wifi on the phone it comes right back.
