Hi javedsaleem,
Thanks for coming back to us on this one.
I'm sorry to hear no one has been able to explain the RS errors for you. A normal connection usually shows a steady spattering of pre-RS errors but there should only be a tiny number of post-RS errors.
To explain this further, when the hub reboots, the first moments are quite chaotic and messy. Data is pouring in, but the modem hasn't yet synced up with the CMTS on our end. As the synchronisation is taking place, at the same time, corrupt data occurs hence the errors.
If damaged packets of data arrive at your Hub, it will automatically try and repair them. If that's successful, the pre-RS error counter will go up. When it fails, the post-RS error counter will go up. If your post-RS error count keeps going up it's likely a sign of an issue with your connection which is why we run the checks that we do. Looking at your logs, all the packets are being repaired which is why you have a 0 post-RS error count.
When there has been an uptime of over a few days it's worth resetting the counter to 0 by rebooting the hub and then checking periodically to see if the number rises.
I have checked all aspects of your network today and there is nothing that I am seeing I'm afraid.
Keep us posted on if you notice the post-RS error count increasing or if you have any further issues.
Thanks,

Hi Javed,
Thank you for reaching back out to us, sorry to see you have been seeing lots of errors on the Router logs, I was able to locate you on our system with the details we have for you and cannot see any issues at all, can you check all internal connections are hand tight, this includes all equipment plus and splitters powered and standard, once done please let us know if things improve.
Regards
Paul.
