Hello,
Running a Hub 3.0 with ver CH7465LG-NCIP-6.15.30-1p4-NOSH on it.
Wondering what basline numbers is "normal" on Pre and Post Errors, here below is a snip of mine:

4 Locked 40.366 107959691 5
*1h after reboot
What I've noticed is that the router reboot itself looking at the logs at the time of the event I see nothing to the cause of this.
MIMO Event MIMO: Stored MIMO=-1 post cfg file MIMO=-1;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0
Any advice on firmware upgrade, replace hardware *cables etc. would be greatly appriciated. Just posting this a bit quick here since I don't have time to sit on the phone for 1h.
Cheers

Good afternoon @andlid,
Welcome to the forums and thank you for taking the time to post.
I am sorry to hear that you have had some issues with your services.
Have you managed to follow the advise from jbrennand? If so has this improved things?
Kind regards,

Hi, actually no. It's used 24/7 and I'd be strung for checking cables . They're all brand new out of the box so don't think that's an issue though to be sure I'd need someone to measure the cabling. I'm currently trying to figure out if this virgin outlet is the main or the one not in the office is. The cabling outside is pitiful to say the least. Today we had a drop on the wifi side too so something ain't right with the service.
I did get a splitter with the box so Will try and remove that since I don't have a tv using the service.

Update:
Took the splitter away from the equation. traced cabling from these two wall sockets one in the office and one in the living room. Both connect to the same splitter looking box under the roof outside. Since this is a bus network I guess (using old COAX) my problem could be on any of the other properties in the link chain. Is it possible to remotely measure where there might be a "kink" / "issue" ?
Below are the numbers before taking off the splitter, will see if this made any difference of the service.

Hello andlid
Sorry to hear this is happening
I am more than happy to take a look at this for you
I will need to send you a private message to pass security
If you can check the purple envelope top right of your screen that would be great

Can se these items in the log:

Comparing the logs from yesterday to today (less then 24h) tells even me that something can't be right with the to me massive increase of number of errors. Guessing the poor little box is working overtime to try and correct and sub affect my wifi?

Having a read around the community it seems I need an engineer on site to see where this problem lies?
