Ping alto, dmesg estranho, s.o.s.

Amigos, tenho um pedaço da minha rede que é um canal entre um AP-1000 e do outro lado uma maquina linux com card pcmcia ORINOCO. O sinal entre os pontos é excelente mas tem horas que o ping fica muito alto até mesmo com baixo trafego.

Abaixo passo o ping e o dmesg do linux:

Alguem tem ideia do que esteja acontecendo e alguma solucao para isso.

Outra coisa, nesse momento o trafego estava na casa de 1 Mbps, mas ocorre esse problema até com trafego de 256 Kbps.

Valeu ...
