Network Log Critical Errors - Hub 3

Hi,

I am new here and I am noticing some critical errors in my hub 3 Network Log as copied below. I've also copied in my stats and config. My hub is in modem mode and I use a Google Nest WiFi router. It's worth noting too that it took me an age just to log onto the hub 3, it was constantly timing out.

Re: Network Log Critical Errors - Hub 3

I honestly don't think there's anything obviously wrong with the stats from the Hub as posted, you can safely ignore the DHCP messages and the occasional  T3 error is fine, it looks as if you're only get one or two every few days. I don't know how long the Hub has been up for but if it's any length of time then the error rates aren't really anything to worry about either.

Are you actually having issues with the internet connection at all - excepting the login issue with the Hub which has always been a bit slow?

Re: Network Log Critical Errors - Hub 3

@jem101 thanks for the message! My Google Nest outdoor iq camera keeps going offline basically. It's like it's being booted off for using too much bandwidth. However the nest wifi router doesn't have much advanced settings to change and so I thought I'd better look at the hub logs to see if there was anything in there. I've been with virgin media for awhile now and looking back I can see these error messages all the way back.
