Since last friday we lost the Wifi at our company. I checked the Aruba A800 controller but he doesn't respond anymore. I can't ping nor I can go to the webinterface.
Today I did a reset of the A800 controller to get a clean config. (With a serial cable, in Putty -> #write erase all) I configured the original network settings as before the reset:
Default gateway: 172.20.0.254
But after that, I stil can't connect to this IP address even though i'm in the same subnet.
The Aruba A800 is connected to a 1gb switch. If I connect my laptop to the same port on that switch, I receive an IP address. So nothing is wrong with the switch.
Also, when i'm in the console (CLI), i can't ping to other servers or clients in the same subnet. The Gigabit port lights on the controller (connected to the main switch) are flickering, so he is doing something.
What can be the problem with this? I don't believe he just died..

If there is no obvious errors in the console and it all looks fine, it could be a duplicate ip address.
Unplug your controller and plug the laptop into that port and see if you can ping that 172.20.0.50 address. Do a wireshark capture as well to see if there is any arp traffic from that ip.
If my post is helpful please give kudos, or mark as solved if it answers your post.

perhaps try to exclude the switch, just connect a laptop with cross cable directly and see what that does.
what is your port config on the controller now?

Thanks for the replies.
I connected my laptop to the aruba controller with a cross cable. Gave the laptop a 192.168.2.1 address and the Aruba 192.168.2.2
Still no connection. Maby the aruba NIC (network card) died?
