Internet grinds to a halt during the day - large number RS errors
I have a hub 3 and in the past few months, the internet frequently grinds to a halt during the day. I've looked at the logs, and there are high Pre and Post RS errors. I have switched off the router to clear the errors, checked and changed the cable, and changed the channel from auto, but the errors have resurfaced. The network log also lists errors, any ideas?

Pre & Post RS Errors - Is this Healthy?
Can anyone advise whether the below are good/bad/to be expected. I am on M350 (in Modem Mode) and over the past 6 months have noticed a decline from our usual 75Mbps D/L speeds to regularly only getting 25Mbps (I would LOVE to think we ever got close to the advertised speeds). I check using the Service Checker in case there are any known issues in our area. In the olden times (we had this installed in 2000 when it was ntl - I was working for them back then) I would just call up and request a Service Engineer to come check (and would be happy to pay) but now I can't seem to get anywhere other than in a perpetual loop of check it myself, reboot the router, check it again. If anyone can point me as to whether the below should be cause for both concern and insisting on a physical visit it would be much appreciated.
