We recently purchased a 4402 controller. It was running the 3.2.195.10 release, which I upgraded today to 4.2.99.0. I also updated the bootloader to 4.2.99.0-ER.
I configured everything like I did before the software upgrade. Same IP address, same subnet, no VLAN tags, and so forth.
The controller is on a segregated subnet, apart from my desktop machine. I have another machine on that segregate subnet, which I'm using for terminal access. I can remote desktop into that machine just fine.
I can also ping the controller from that machine.
I can not ping the gateway from the controller. I can ping the remote computer from the controller.
I can't ping the controller from my desktop, and I can't ping my desktop from the controller.
Any thoughts? The only difference is the upgraded software, as far as I can tell.
Thanks!
