New install (M500): Scatty speed results

I've just done a self-install today.  Speeds are all over the shop.  I've achieved 500Mbs speeds from time to time (both wired and wireless), but it's dropping significantly and the median seems to be around the 120Mbs mark.  I'm using the Hub 3.0 in Modem Mode, though I have also tried using the Hub's own wireless.  I use Amplifi kit in modem mode which has worked very well with a recent G.Fast 300Mbs connection, so I know that Wi-Fi is good here.  I've rebooted the AmpliFi kit a couple of times during my testing.

Hub 3.0 stats.  SNR seems to be reasonable to me.  So I suspect possible congestion in my area (26) or maybe something else.

As a self-install, I didn't have a wall socket - rather when I originally had Virgin Media in the house many, many years ago, the engineer put through a single coax cable through the wall (and a separate phone box) from the box outside the house.  I used the old cabling from my previous installation from 2018 and it seems to be okay.

Excuse the mess, everything is in a state of flux right now!).  The first image shows the incoming coax cable from the outside, this goes into a TRIS-1002L isolator, which then goes into a splitter for the TV (which I don't have) and the Hub (second image). 

I had initially tried the isolator + the bundled isolator (since the supplied cable was male, and the coax that comes in was also male), and that worked, though having two isolators seems .. strange, so I reverted to the old set-up I had back in 2018.  All seems fine apart from the inconsistent speeds.

Update: Since rebooting my Netgear switch, and performing another restart of the AmpliFi router, speeds have improved somewhat.  But then again it's 12:30am, so people may have gone to bed 🙂

Re: New install (M500): Scatty speed results

Hi mbdrake,

 

Thank you for your post and welcome to the community. 

 

I'm very sorry to hear about this. I have taken a look on our side and I am unable to see anything that could be causing this issue. 

 

How has your service been since your post?

Re: New install (M500): Scatty speed results

It looks as if I just needed to reboot a switch (and the AmpliFi router) - that looks to have done the trick and speeds have been what I'd expect them to be.
