A few Uncorrectable Codewords errors are okay but the DOCSIS 3.1 channel should have very few, if any.  You have 19864.  You should ask Rogers to investigate this.  You can either call tech support or you can send a Private Message to @CommunityHelps  for assistance.

I've been here awhile

Hi, my Modem's internet connection keeps dropping every few minutes (Orange blinking, ethernet and wifi disconnects). It goes back to solid white with connection about 30-60 seconds later. It's been like this consistently for a week. It looks like I have a high amount of uncorrectable codewords, see below.
Is there any way to fix this, or is my only option to request someone to come look at the lines?

I assume this is normal as I haven't really experienced any dropouts, I never get a stable gigabit though

@stepy2015  No, this is definitely not normal.  It is totally fine to have a HUGE number of Correctable Codewords errors on a DOCSIS 3.1 channel but the Uncorrectable Codewords stat should be zero (or as close to zero as possible) across all channels.  85240 Uncorrectable Codewords on the D3.1 channel is TOTALLY unacceptable.

So how do I get it investigated? because when I get the techs to run tests they say everything is fine, even level 2's

Call into Rogers tech support right now, with the Ignite gateway in its current state.  Do not reboot it (or allow them to reboot it without investigating first) because that will zero out the stats.

 

When they see those error stats, they should see that your service is clearly not working properly.

Wow, okay.  That's not good.  You can also try sending a private message to @CommunityHelps  and ask them for a second opinion.

Re: Uncorrectable codewords

@bestjsg1 @Quinnler @stepy2015 when you post the codewords, can you also post the signal level table as well.  It would be useful to see where the signal levels are, at the same time that you posted the codeword table.
