Lots of Errors & Profile Assignment Changes
There seems to be something not quite right with my connection, which has been going on for around 2 years. I did have an engineer visit, which helped the disconnections, but the Downstream and Upstream errors, never seemed to improve. Also getting lots of profile assignment changes in the logs. I recently switched over to modem modem and installed a new Deco Mesh system and decided to revisit this issue. System has been up for 52 days and I plan to reboot today. Potentially need an another engineer visit, but would appreciate the feedback of the community.

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? Logs below: Channel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID 1 267000000 2.9 38 256 qam 17 2 275000000 3 38 256 qam 18 3 283000000 3.2 38 256 qam 19 4 291000000 3.5 38 256 qam 20 5 299000000 3.7 38 256 qam 21 6 307000000 3.7 38 256 qam 22 7 315000000 3.7 38 256 qam 23 8 323000000 3.7 38 256 qam 24 9 331000000 3.7 38 256 qam 25 10 339000000 3.7 38 256 qam 26 11 347000000 3.7 38 256 qam 27 12 355000000 3.5 38 256 qam 28 13 363000000 3.7 38 256 qam 29 14 371000000 3.4 38 256 qam 30 15 379000000 3.2 38 256 qam 31 16 387000000 2.7 38 256 qam 32 17 395000000 2.5 38 256 qam 33 18 403000000 2.2 38 256 qam 34 19 411000000 2.4 38 256 qam 35 20 419000000 2 38 256 qam 36 21 523000000 1.7 38 256 qam 37 22 531000000 1.7 38 256 qam 38 23 539000000 1.4 38 256 qam 39 24 547000000 1.7 38 256 qam 40 Downstream bonded channels Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 1 Locked 38.6 6103 29372 2 Locked 38.6 5882 28746 3 Locked 38.9 6887 26860 4 Locked 38.6 10108 22585 5 Locked 38.9 12039 19624 6 Locked 38.9 17120 13776 7 Locked 38.6 19928 10383 8 Locked 38.9 21590 9071 9 Locked 38.6 21831 8239 10 Locked 38.9 21947 7394 11 Locked 38.6 20830 7828 12 Locked 38.6 19614 8410 13 Locked 38.6 17856 8503 14 Locked 38.9 17994 8577 15 Locked 38.6 17651 7446 16 Locked 38.9 16744 7319 17 Locked 38.9 15496 7436 18 Locked 38.9 13588 9366 19 Locked 38.6 13500 296325 20 Locked 38.9 12102 7787 21 Locked 38.6 3513 9541 22 Locked 38.9 1670 9757 23 Locked 38.6 1966 9767 24 Locked 38.6 1344 9701 Time Priority Description 15/07/2024 11:41:8 notice LAN login Success;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0; 15/07/2024 04:05:19 Warning!

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.
