Put a different AP online last Friday. No disconnections or problems seen since.

Hmmm.. okay.. devices are disconnecting and not reconnecting but to which device, router or extender? Are the two wireless bridged or wired? How far apart?

Re-test with 2600 only and power off the 1300.

I'll setup the COVR as a router for 32 devices in my lab and see how it behaves. I have about 13 wireless devices and 19 wired devices, mostly cameras.

Not connecting back to the 2600. I havn't been using the 1300 extender at all. Just the 2600 alone in LAN to LAN AP mode behind a different main host router. That routers wifi radios are turned OFF.

I see an issue with the 2.4ghz. Once you start a continuous 1mbit+ transfer from 2.4ghz to LAN, packets are dropped but only on traffic coming in/out of 2.4ghz devices. Everything else is working as expected and 1300 is powered off. Channel selection is not allowed on this model, so its been stuck on Channel 5, even though it should be set to automatic selection.

A different channel might change the behavior, so instead a (DIR-879) was tested on the same channel 5 with the same number of devices connected. The results were identical, packets were being dropped once load is applied onto the 2.4ghz medium. However, as soon as the channel is set to 3, packet lost dropped to 1-4 % range.

If I can change the channel on the COVR, then maybe we can figure out if this is wireless interference or a buggy firmware.

FurryNutz, is the 2.4ghz channel on your Covr fixed to 5?

[FurryNutz]

I'll have to reconnect it and check and the 890L has been online and working flawlessly. 

I'll get it reconnected today and check for you...

SSID is Airport Extreme highlighted in Green.

This is the DIR-890L, looks like channel 11:


This is the COVR, looks like channel 5. Also Protocol seems to report AC instead of B,G,N for 2.4Ghz?

In a wireless shielding room, the engineers manage to change the channel other than 5 and they were able to influence by a 2nd router.

For some odd reason, my unit is stuck on channel 5 no matter which location in our building. I may have to take this home to test.

FurryNutz, you may have a better chance on your side. Let me know if you can get that to change.

[FurryNutz]

I haven't been able to while using it on it's own. Seems to like chl 5. I can set up a different router and configure it to channel 5 and then bring the COVR online and see what channel it picks...

[FurryNutz]

Ok, I set my 890L to disable SC and manual channel 5 downstairs. I connected the COVR router and changed the SSID name so I could see it.

Before COVR was online: Airport Extreme SSID on 890L


After COVR was online, It still shows channel 5 even with the 890L on same channel: Airport SSID name for COVR

[Gattsu]

I have conducted the same test and I set the 2nd router to channels 4,5,6,7, and 9, but the COVR still uses channel 5.

What is the serial number on your COVR?

[FurryNutz]

SY551H7000499

[Gattsu]

It seems there maybe an issue with the COVR's automatic wireless channel selection process. It is being look at right now..

[FurryNutz]

What I was thinking.  Hopefully the problem can be fixed. My unit is ready for testing.
