Getting sluggish internet speeds compare to the M200 speed that is advertised which seem to have got worse since the local "upgrade". Reliability has also worsened. I have tried using wifi and wired direct to the hub. The latter has achieved slightly better speeds. I have tried multiple rebooting of hub. The hub is a Super Hub 2ac. I have used Ookla speedtest at various times of day and days of week with wired connection using laptop with Windows 10 and latest versions of both Chrome and Firefox. Maximum ever achieved is 89 Mb/s download and 21 Mb/s upload. More usual download speed is 30-50 Mb/s and sometimes less than 1 Mb/s. Upload speed varies between 10 and 21 Mb/s.
Network log, downstream and upstream channels are as follows.
I have removed a 2-way splitter that the Virgin engineer inserted in the line to my router. This has improved the download signal levels (see below). Are these now OK or do they need to be even higher and therefore need an engineer to turn up at the cabinet? Download speed has not improved though - measured about 70 - 90 Mb/s this evening on a wired connection direct to the router.
The Superhub 2ac is hardware version 1.03 and software version V2.01.15.
