M200 broadband download seed only reaching 10mbs max

M200 service speed used to be good (100mbs or more) but last few weeks much slower. Download never better than around 10mbs with upload 20mbs

Have reset router, tried hard-wired devices to rule out WiFi issues, have run VM checks which come back reporting no issue. There is also no faults on the VM status in my area

Looking in the HUB 3 router status, all of the the 24 downstream bonded channels have lots of Pre RS and Post RS errors, so not sure if this is pointing to the issues 

Is anyone able to offer any assistance please?

Hello

Lots of Post RS errors tend to be an issue with noise, can you please go around and make sure that all coaxial connections are finger tight, best way is too loosen then and re-tighten them, then power off hub for 30 secs and then back on.

If your post RS errors keep rising at a large rate can you post the downstream, upstream and network logs here and the community can have  a look.

Regards  Mike

Hi Mike

After doing what you suggested, the Post RS errors are now at zero and Pre RS errors in single digits. This is after 10 mins of uptime / use. Download speed is back to the 160 - 180 mbps rate

Thank you so much for helping me out

Neal

Re: M200 broadband download seed only reaching 10mbs max

Disappointingly, the slow speed issue has returned

10.6 mbs on a 200mbs service

The post RS errors have not returned but the pre RS errors are increasing

Below are the screen shots. Is anyone able to advise on next steps please?
