Internet stability on full fibre

[Robrat]

Hello - in recent months I've switched to Sky Broadband, full fibre to the property. We were previously with BT, with no issues. Since switching to Sky the internet stability has been woeful. We first noticed this with the Sky Stream puck we got - where the TV signal drops regularly and intermittently. Sky replaced the Stream puck to rule out a hardware issue there, but it didn't help.

Other devices have had similar - but slightly less noticeable issues.

Sky stream issue I've experienced both on wired and wireless connections - so it's not a wifi interference issue.

SPEED isn't the issue - albeit this morning I had download speeds in excess of 700MB and upload speed had dropped to 0.5MBs.

I'm hoping someone will tell me that there's some magical thing that can be done by Openreach to fix it. Any other self-diagnostic things I can look into?

I've been running a stability/ping test in the background - and while the average is fine, there are regular very high peaks that I'm noticing.

Just tried another reset and changing some cables around. Now back to this. What on earth would cause such a poor upload speed?

Getting nowhere on this with Sky customer support. Told today perhaps I have too many devices connected to wifi - I don't, but even if I did (20 by the way, most of which are IoT devices using almost no bandwith like my washing machine and car charger) Sky's 1GB FTTP should be able to handle that.
