871 hanging for security problema

[marisg1979]

Hi,

I have a 871W router that's been hanging daily for several weeks now. I think it is under a denial of service attack (I'm quite new with this security problems).

I'm attaching the log, if you can help me with the diagnosis and give me some recomendations.

thanks in advance,

Mariana
