Can anyone please do a small easy test, do you have this issue?

Initial state: any OpenWRT CC build, enable wireless and encryption.

Step 0. No wireless clients.
Step 1. Do: client A - connect to 2.4 GHz
Step 2. Do: client B - connect to 2.4 GHz
Step 3. Do: client A - disconnect from 2.4 GHz
Result: client B - goes offline (connection is associated, but network not available, no ping).

You can use 5 GHz connection for both clients too.

I will be firing up a WRT1900AC V1 and will test this scenario for you but I need to know which CC image you are running.

Chadster766, thank you. I've tested:
- official build 05-May-2015, r45601, linux 3.18.11, https://downloads.openwrt.org/snapshots … u/generic/
- official build 18-May-2015, linux 3.18.11, https://downloads.openwrt.org/snapshots … u/generic/
- Kaloz build 23-Apr-2015, linux 3.18.11, https://downloads.openwrt.org/people/kaloz/
Any build have this issue.

Ok will test those out.

Any build is interesting to me, it is strange that no one is mentioning this issue, maybe any other popular build doesn't have this issue.

You won't be able to score a v2 for quite some time.

I'll keep the v1 then.
Somehow I predict that the v2 will sooner or later have overheating issues, so that fan might come in handy.

WRT1900AC V2 is shipping. The below link is to a thread where a user has one and is doing a review:

http://www.snbforums.com/threads/linksy … ost-183613

I did the testing as described with both Kaloz and Trunk images on the WRT1900AC V1.

Testing was done with IPv4 only and the default wireless settings except I changed the 5Ghz SSID to OpenWRT_50. I never have both the 2.4Ghz and 5Ghz SSID the same as a policy. My desktop (Client B) wireless adapter is set Static IP Address 192.168.1.2 and my S5 (Client A) is DHCP.

Client B could always ping 192.168.1.1 whether or not Client A was connected.

Looks like this might be an issue with your OpenWRT settings or wireless adapters.

Chadster766, thanks. Both clients were connected only to 5 GHz? Encryption was enabled? Did you followed order (nothing connected, then first connect A, then connect B, then disconnect A and check B)?

I'ed like to see uboot's boot log.

In your test description you only mention 2.4Ghz so I didn't do 5Ghz but I can if you want.

Yes I followed the connect and disconnect order with only two client devices.

No encryption since those are the default wireless settings.

Question are you using a 4 letter password for WPA\WPA2 encryption? Shouldn't that be a minimum of 8 characters?

Chadster766, please enable encryption, it is required to trigger the bug. All other is ok, I've incorrectly read your message about 5 GHz, you can leave 2.4 GHz. I've used 8 character password, it was just masked in my post, sorry for confusion.

Sure i will enable the encryption and do the test again.
