I have been having trouble with internet speeds dropping significantly (< 5 Mbps download speed).
I'm on the M600 Fibre Broadband plan, but I cannot say I've ever done a speed test when things "work" so I wouldn't even know what to expect when things are running optimally. Maybe this has just become normal for me...
Thinking about it now, it is entirely possible I've never reached the speeds I should be getting.
I've not been actively monitoring it in terms of measurements, but clearly there are periods when things get slow enough for me to notice and do a "speed test" and there have been a number of times since March 2022 that I have noticed this occuring.
During the problem times, download speeds hover around 5 Mbps, with upload speeds 3-4 times better (so 20 Mbps), ping is 25 ms.
Today after speaking with VM on the phone, things later improved for around 2 hours (5-7pm) and I was able to reach 150-200 Mbps, but now things are back to where they were.
Naturally I'm using my own ASUS router with the VM one in modem mode. Although I've tried over ethernet and not recieved much better.
