Hi.
I'm not the account holder, but she's asked me to post this topic.
After a long period of poor service performance on an M350 package, our household was upsold to M600 in July 2021 on a support call. Since then things have degraded further. Disconnects until power cycling the hub are common, pinhole resets are unhelpful, and we get at best 5% of the listed service bandwidth - usually, weirdly, with better up than down.
Our LAN has been running 600+800 WiFi and PLC and performs close to theory for ping spam and transfer tests *before* reaching VM hardware. We're at a point where we're now upgrading to WiFi6 6.6gbps local but are getting a tiny fraction of our expected WAN performance.
We've had the street to hub fiber replaced once recently by a virgin engineer during landline deprecation.
The following table is speedtest results with extraneous data omitted for a device capable of gbps networking, connected to a hub 2, then later hub 3, both in modem mode, with cat6 and more recently cat8. All are 4 server, 0 miles, performed with no other connected devices. Note that while the test dates aren't regular, it's always this bad.

I haven't kept long term hub runtime logs. RCS Partial Service spam is common, as are sync fails. For example, in time with the most recent test and some time after a power cycle:

Technical aside, for a long time we'd have had better, cheaper line performance with something running from the local exchange; I'd appreciate any help I can get.

Hi gillgrawlings, thanks for the message and sorry to hear that you are having issues with the service. I will send you a private message so that this can be looked at further. - Chris.
