Atualizar Firmware AP2000

Galera,

Estou tentando atualizar o firmaware de uma AP2000 Proxim, pela interface http não faz nem o download, aí utilizei o Telnet configurei e fiz o download, mas depois do download ela dá a seguinte mensagem:

File AP2000.bin is being downloaded from 200.213.33.25.

An error has occurred while downloading file AP2000.bin

Vejam a configuração, o que pode estar errado?

[ORiNOCO AP-2000]> show tftp
