Intermittent slow speeds (~0.5Mbps) for 30s, Modem Mode, Normally 300Mbps+
a month ago
I've seen similar posts to this one before, but they all either end without resolution, or after a VM member starts a private chat with the OP.
I get intermittent slow speeds on my VM 350 connection. Some days this will happen every 5-10 minutes, dropping the speed down to ~0.5Mbps, before returning back to ~full speed. Some days are without issue.
This happens on wired connections as well as WiFi.
I'm using Modem Mode, the router is an EdgeRouter X. Speedtests on the ER also show the same slowdown, so I'm fairly confident it's the VM hub.
Basically - Downstream should be between -6 and +10dBmV with an SNR above 34 and RxMER similar!
Upstream power should be between 34 and 51 dBmV at 64 QAM
There is a really good 'sticky' post that goes into all the technical side of it - but this is generally what VM looks for! - If your network log or BQM (see my signature) looks horrendous and all the levels look OK - they will usually still book an engineer as there is clearly a problem! This is why it is good practice to keep a BQM going!
Gave them a call, apparently there's a local issue currently due to performance improvements in my area. I doubt this is affecting the issue as I've had it for months, but they said no tests could be performed reliably while this work is taking place.
I'll try again on the 9th when it should be completed, if a rep doesn't appear here sooner.
