Covr-1203 WiFi hangs intermittently

(1/7) > >>

m8377:
I have setup my system to use Ethernet backhaul with both B nodes plugged into an unmanaged switch. Sometimes when I am using a device (browsing internet, streaming video) it will become slow for up to 20s on that single device. I managed to get a speedtest running during this and my speed goes from 80mbit -->1mbit during the slowdown.

This can happen when I am in the same room as either the A or a B node where the device has no reason to switch between nodes.
Running Hardware A, FW 1.05. I have started logging to a syslog server and can upload the log on request. Same with screenshots/setting.bin.

Any ideas on what would cause this?

Edit:
After 5min of syslog I have almost 2k lines that are almost all spamming these messages https://imgur.com/a/rhbshFN

What is the distance between the router point and the remote points? Feet?


* Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?

* What region are you located? Canada - We share most hardware/software config with the US. Hoping this may be an issue with US version as well?


* Has a Factory Reset been performed? Yes

Internet Service Provider and Modem Configurations

* What ISP Service do you have? Cable or DSL? Shaw Cable

* What ISP Modem Mfr. and model # do you have? Hitron CGNM-2250  set to bridged mode

What is the distance between the router point and the remote points? Feet? Both B nodes are ~20ft from the main node, about 2-3 rooms away.


* Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences? There is a 2.4ghz home phone. 0 nearby WiFi networks on 2.4 or 5G.

After resetting I though I would try setting up the B nodes as wireless. Now I see the B nodes connect, get the solid white light. Then after 2-5 minutes the light will flash orange, white then go solid. If I unplug the B node and measure the wifi signal it looks stable.

FurryNutz:
Ok, 20 feet maybe a bit too close. I would try 30 feet if wireless with the B remotes.

So when Ethernet connected to the B Points, any switches in between the A router and B Points? If so, Mfr and model# of this switch?

I would test the current wireless configuration with B points wirelessly connected to see if anything continues to hang. Keep us posted.
If nothing hangs, I would then connect just 1 B point via ethernet and test again.

I have encountered similar problems with my COVR 1203 system.  In wireless mode it works fine and has been very stable.  But as soon as I plug a cable into one of the ports so that it goes into wired backhaul mode, it can become unstable.  Sometimes an individual node appears to vanish from the network.  Other times connected devices become unresponsive.

After playing around with it tonight, I am seeing a tripling of performance with the nodes using wired backhaul as compared to their wireless throughput, and yet the nodes are constantly flashing orange, and the management interface reports a "Weak" quality connection.  And yet I'm getting 300mbps from them, so there's nothing wrong with the connection.

All the nodes and the A (main) point are connected to the same unmanaged switch.

Any ideas as to what may cause the occasional instability, or why the nodes flash orange?  Maybe the backhaul software is buggy?  It was just added in the latest revision (1.05) from the looks of it.
