Buffalo AG300H connected to a Cisco dpq3925 donīt work

[Jakkov]

Hello,

 

I have a Cisco dpq3925

Connected to this router I have a Netgear WNDR3300

Then I have connected to the netgear a Buffalo AG300h

 

This combination works perfect with no problem.

 

But when I try to connect the Buffalo directly to the Cisco DPQ3925, I can not connect to the internet (I check the cables and are perfect), I can access to 192.168.11.1 with no problem but no internet.

 

Could someone help me to have access to Internet?

 

Thanks a lot.
