Hi Ilya,did you made a upgrade recently?What FW Version do you need?Are all SSID's affected?I would suggest to update to 10.41.07. Disable 11k/MFP/fast Transistionif enabled.We need more details.RegardsUmut Aydin
Is that the same SSID that works for 2.4GHz & 5GHz and not even one client works on 2.4GHz ?Do you use the load group feature on this SSID.
OK let's do that step by step....Is that the same SSID for 5GHz and 2.4GHz ?Per the describtion the clients on the 2.4GHz are connected to the SSID but get no IP.- are they authenticated = if you check the client/SSID report to they all have the green lock in the first row- who is the DHCP on that network, is it the controller or a ext DHCP- does the communication work if you set one client with a static IP
I've been seeing this on 10.41.08, I'll have to dive into it this week. We only have a few buildings with 3825s and most devices support 5GHz, the rest of the campus is still 3710s and they work fine on 2.4GHz (you can actually walk from one building to another and the 2.4GHz only device connects as soon as you walk out the door). So it's a 3825 specific problem I think.
