Router stopped working for no reason
This morning, I noticed Wifi AND direct Ethernet connections had no internet access from my RBRE960 router. I checked the Xfinity app, it said the modem was online and fine. There was nothing in the ...
To answer everyone's questions:
FURRYe38 I submitted a support ticket!
How many days was it online before this happened this morning? 7+
Only thing I can think of is enable debug logging on the RBR at start up and if it happens again, see if you can save off the logs. ---> I couldn't access either the router admin web page or any running lan/wan capture logs when it happened. So that probably won't be useful.
CrimpOn I could not get access to the debug page - I tried that. The network was completely down!
Ok, Ya hoping that NG can figure this out. Should not happen. Only thing I can think of is you've seen odd behaviors since you installed the XS series switch. 🤔
It could also be related to higher speeds - I used to be 1GB now it's 2GB. Probably not a ton of customers running at that speed on Comcast (which they have clearly had challenges with). Also, if they can't/don't test a ton of long-term issues, that would fit in - it ran perfectly for 7+ days.
Let's be honest here, there's potentially bunch of issues - pointing to firmware code that needs some serious walk-throughs, code audits, updates where later open source versions are available, etc.
What we have seen:
1- IPv6 issues - just Comcast maybe? Related to using Comcast DNS servers? (that has gone away by using Google DNS servers)
2 - Power cycle of the RBS then RBR, or just reboots will frequently require second power cycles of satellites (850 and 960 series) due to hop count being 0/blank so nothing can connect to it.
3 - system comes up unstable with 2 RBSs with ethernet connected backhaul - solution is often to let an RBS sync wirelessly then move it into position for wired backhaul
4 - adding a switch (XS508) and moving RBSs over to that switch, using their 2.5G ports, caused WiFi speeds to drop to 10% of their normal speeds starting 24 hours later.
5 - IPv6 requires about 125MB extra memory on the RBR - happens to some customers, most do not see this. Related to issue #1?
6 - FURRYe38 haven't you seen memory and CPU usage creep/increase that doesn't go back down?
Anything else?
