sudden decline in Mbps being reported by speedtest using Chrome

[moof]

I routinely check and record my speeds to keep an eye on what I pay for vs what I get... on average I'd say I'm around the 900Mbps mark and happy with that on a 1GB subscription. Have done this for years.

ethernet connected, third party router, VM Hub 5 in modem mode

 But since the turn of the year it fell off the cliff....way down 😕

Initially I opened a VMchat and said my connection speed was looking slow and they said "we can see an issue with your router we'll arrange an engineer" ...the date set was the same day I had also got info they were doing works in my area midnight-3am. I also wasn't convinced the VMagent realised the Hub5 was in modem mode.

However after coming off the VMchat I ran the speedtest in an alternate browser and got a VERY different result, so cancelled the engineer.

Nearly double!   Chrome was around the 370/98 Mbps mark, Safari 782/100 Mbps. Same computer, same ethernet connecting, two different browsers.

....to throw a huge spanner in my investigation I was on a Win11 ethernet computer in another room and Chrome gave me a result of 209/856 (yes - upload was massive compared to download 😳). But I digress.

Digging a little, I'm down the rabbit hole of turning off extensions in Chrome, clearing cache, fresh profile yadda yadda but no dice. If I use Chrome I'm seeing a HUGE decline in the reported speeds

Anyone else?

I'm in modem mode and only use the speed test incorporated in my Asus router settings as a reliable test. Check your hub stats too re power levels and set up a BQM to further monitor your connection. The link is below.

Unless there are obvious signal level or error rate reasons don't assume this has got to be a Hub problem.

Excluding web browsers will give a more dependable result.
Try with the Speedtest Windows program.    https://www.speedtest.net/apps/desktop

+1 on use the speedtest app instead.   Thee's windoze, Mac & mobile versions available.

I see quite a range of results with various browsers on most speedtest sites.

Download a game from Steam is a better test

Hi @moof thanks for your post here although we're sorry to hear of your concerns raised.

We've tried to run checks and it seems this isn't fully possible so is your Hub in Modem Mode perhaps?

If so, we'd not be able to advise fully as this does take it out of our hands when a third party Hub is in play.

We do hope this is resolved soon for you but if not, please take your Hub out of Modem Mode and come back to us.

Many thanks
