Slow internet and collisions

[eduardo.seijas]

I have configured a 861 router and I'm seeing that the internet connection is slow and it is also saying that I have collisions.

How can I fix this?

I'm attaching the configuration file.

Have you tried hard-coding the duplex settings of both sides to full duplex?

You mean configuration the wan connection to full duplex?

Yes.
