I do not know what is happening with my router, connects in a few days my users saying that the connection is not responding.
So I try to access remotely and does not respond to ping.
Interface console appears the message "Low on memory; try again later."
This is already the second router I'm using, I changed two days ago, and now caught again.
There is only a single wireless router connected to the network interface, which covers four users.
Attached with the settings and the screen with the problem.
