Modem Speed Vs Router Speed

[angelj211]

Hello.

I have my own modem and router.

                      Modem- Motorola Sufboard SBG 6580

                      Router- Linksys ea6500

                     I have Cat6 cables hooked up to everything. 

When I hook my computer up directly to the modem I get 117 MBPS. 

But,  if i take that same cable and hook it up to the router, which is also a gigabit connection and is hooked up directly to the modem via Cat6 cable, I get 30 MBPS. 

Does anyone know why that is?

Thank you.

6580 is obsolete, only does IPv4... but that's not the issue..

 I'll bet you didn't put the 6580 in bridged mode and are double NAT'ing.

Thank you!

I dintn't even think about bridging it.

That seems to have fixed the issue!

You can double nat but the gateway and DHCP starts need to be different subnets...

first one  192.168.1.1   second one 192.168.3.1  but you're better off bridged and in total control of your router.
