Slowdown in the evening

On our wavelength


First I'm an IT person so I've tried the obvious...

I have a Hub 3.0 and the contract is Volt 350.  We also have O2 sim only so should get a boosted deal.

I also have the hub in MODEM mode, and use a Sophos UTM as a router.  I say this as I don't want to have a conversation with 1st line support who will want me to rejig the house setup to use the hub in router mode if its I can help it.    Typically I get about 200m bps.  I know it could be higher but I'm gessing there is an overhead in the appliance but dont worry to much.
Recently in the afternoon our speeds drastically dropping according to,  it coud be contention but I'm also see ing CM errors.    My PC that I test on is wired to a gigabit switch and on to the router, so its dont think its a slow device creating I'd see that all the time not just the evening

This morning (8am)  I got about 190 ish MBPS but tonight (17:47) speedtest is reporting 28.85 mbps. 

I think this is probalby going to need a engineer call out, There are lots of RCS errors in the network log (mac partially redacted), I'm just looking for some confirmation before I fight first line support and a fixed script about going to router mode on the hub....

Can someone case an eye over it and say if it looks OK or do I need someone to do some local testing?
