Slow 500 service

[WYNIR0]

Upgraded last week from 350 to 500 and even after a call to service team where they sent a new profile to the Hub I'm still maxing at about 320 whereas I peaked at 380 before.  Will post router stats below. Is anyone able to assist please?

COnfig looks fine - deffo the 500

How are you measuring your speed?

[WYNIR0]

using the speedtest.net app from a  pc directly wired to the router attached to the Hub. 1Gig Nic and all Cat 6 cables.

Hi @WYNIR0

Thanks for your post 🙂 

I'm very sorry to hear you're experiencing slow speeds, I appreciate this is frustrating and we apologise for any inconvenience caused. 

How have things been since posting? I've managed to locate your account and I can see the team sent hits and requested a reboot, has this helped improve the speeds for you? 

Let us know.

Thanks,

@WYNIR0 What's the position on Downstream post-RS errors? When you last posted those there were a bad number of those.  A post-RS error is a data packet that can't be corrected by the hub's on board error correction, and so the data needs to be re-requested.  That will usually have a dramatic and bad effect on speeds, and the cause is radio frequency noise ingress through a faulty joint or cable.  Be aware that a reboot of the hub resets the error counters to zero.  As this affects lower frequencies, a possible cause is emergency services radio, ham radio or aviation & radar, in which case the noise may be intermittent.

Try undoing and redoing the coax connections for the cable to the hub (finger tight only, both ends of the cable, plus any other VM coax connected gear like splitters or TV boxes).  If after that you still see rising post-RS error counts then it will need a technician visit - the remote "kick" VM can give the hub won't make any difference to a noise ingress fault.

Thanks, Speeds still around 300 Mbit. I've been busy with work and kids so not had a chance to look any further as yet. Am on leave for a few days after today so will spend some time on it, check connections, keep an eye on Post RS errors and report back.

Appreciate the assistance everyone.
