SRX 240 with access point hang

10.18.11   |

We have 4 access points with 2 ssids, it seems like every few weeks that the APs will hang, and when users connected to the ssid, they still can see the ssid broadcast, but when they connect it, not able to get ip address. SRX is the dhcp server for the ssid, after we reset the AP, then users will get the ip address as normal.

Just an idea maybe:

 

user@srx>show system services dhcp binding  

 

You can check if you have too many DHCP clients and if they are aging out correctly.

 

From the notes on the following AX411 Release notes:

 

Outstanding Issues for the AX411 Access Point
The following items describe the outstanding issues for the AX411 Access Point:
• After a period of time ranging from several days to several weeks, Radio 2 stops
communicating with wireless clients. The radio still sends beacons, and clients can
still see the SSID, but when they attempt to connect to the network they do not receive
an IP address. The workaround for this problem is to execute the restart wireless-lan
service CLI command on the SRX Series device that manages the access point.

But i only have radio 0 and radio 1, Radio 2 stops communicating? But the symptom described is exactly the same, so no choice have to wait for next release firmware?

Looks like the issue in question, if so, its a bug and you will have to try another release.

 

JTAC is the way, they may be able to give u direction to a working version or an ETA on the next release.

Upgrade your SRX firewall with the latest Junos recommended release i think your problem will be resolved.
