Wireless Clients Unable to Resolve Gateway - HELP (Possible Bug?)

[craig.cartlidge1]

Hi,

I have a situation where wireless clients are not able to resolve the Layer 2 address of their default gateway (I can see this via an arp -a command on a wireless client), this is on our guest SSID, the controller sits in the DMZ along with the gateway. This does not happen all the time (once every 5 days?) but can only be solved by a restart of the anchor controller. we are running software version 7.6.130.0 .

Has anyone had this sort of issue before and how did they resolve it? is it a bug? we are unable to upgrade to version 8.1 of code as we are still running a number of 1242 AP's

Thanks

Since it is almost buggy behaviour, I would suggest to move on to 7.6.130.26 which is the TAC recommended version for 7.6.x

Here is the listed bugs fixed in that code.
