BT Business Broadband connection having intermittent high lag

marcl — Fri, 18 Aug 2023 10:15:57 GMT

I was a long time customer on Home Broadband (Halo 150 i think) and then moved to BT Business Enhanced Fibre 76 (I think) because I need a static IP for my work. It is not FTTP, but FTTC. I have a Business Smart Hub 2.

I still want to use the connection for streaming and some gaming, but expected that to be fine.

The connection went "live" on Friday last week but due to an Openreach issue didn't actually work until Monday (issue with jumpers in the cabinet).

Since Monday following an Openreach visit and fix at the cabinet, the connection has been "stable" I guess, but there have been huuuuge periods of high lag.

During these periods pinging google.com from the Ping screen in the router admin screens is giving over 1000ms. The download speed crashes to almost nothing, as does the upload.

I set up PingInfoView to run a ping every 20 seconds and you can see here how it presents. Connection is running well then apropos of nothing, it starts spiking like mad and then is consistently high ping for a long period (could even be a couple of hours).

I also run PingPlotter, and here is what it looks like:

I'm being told the connection has a 10 day "settling in" period but this feels vague and wooly to me.

Does this look normal for the "bedding in" period? It's unusuable during these times, which is a big problem for me.
