[Reposting this, since my original thread disappeared.]
I have an M200 fibre broadband (200 Mbps download and 20Mbps upload) for few years.
Download speed are pretty stable, but upload speeds often drop, especially in the late afternoon/evening, to 1 or 2 Mbps. Even attaching a small document to an email would hang and often fail.
This is going on since at least 23/October (1.5 months).
I tested this from a wired connection. Virgin hub (v3.0) is on modem mode, by the way.
I have tried to reach the technical help desk but they said they see no issue on their side. I have also sent a more formal complaint two weeks ago, but received no reply.
What could be the reason for upload (but not the download) speed to drop? Could it be an area utilisation issue?
On the network log I see things like:
If relevant, the following info has been taken when the issue was NOT present (if it matters):
Upstream bonded channels
Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID
Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts
I have also just set up a BQM:
Any help/insight would be greatly appreciated, thanks!
