Regular dropouts - day and night

For many weeks now I experience regular loss of connectivity for seconds/minutes at a time.  This is on both wifi and wired connections.

Re: Regular dropouts - day and night

Connect to the hub by clicking on this link http://192.168.0.1/  That should pull up the log in page for the hub.  But don't log in, just click on the link "Check router status"  That'll bring up a window with five tabs.  Open the Downstream tab.  Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here.  Post that, do the same for the Upstream and Network log.  You'll get an error message when you post the Network log, just click on "post" a second time.

Then we can check for any obvious problems with power, noise or error counts.

Re: Regular dropouts - day and night

Downstream SNR is borderline on some channels and too low on the primary (channel 1), with serious error counts as a result (post-RS are the problem, pre-RS are usually not significant).  

I've marked your post for the forum staff to advise - might be an area SNR problem in which case it'll be under investigation already, if it's unique to you they can assign a technician to come and fix it.

Re: Regular dropouts - day and night

Good Morning gybe,

 

Thanks for your post on our Community Forums and I'm sorry to see you've been having issues with your connection.

 

Looking into your router stats on our system and it appears that one downstream channel is slightly out of spec (Modem SNR)

 

I can also see the hub has and uptime of 6 days, can you please either perform a basic reboot for me, or if possible, can you please try a pin hole reset?

 

Kindest regards,

 

David_Bn
