3400v2 Wired Connection Throttled!

Hello,

A couple weeks ago I upgraded to 100mbs internet and noticed I was only getting around 50-60mbs when connected through the router.  When connected directly to the modem (ARRIS) I see 100-110mbs.

 

I have tested the cables and both transmit the full 100+ so cables are not it.  I have reset the router countless times, maybe around 15-20 along with modem reboots throughout also.  I have tested all four output channels on the back and they all are the same.  After resetting router I have both manually setup and let the wizard setup the connection.  I do have the latest firmware version 1.0.0.54_1.0.82

 

My settings are:

Interent Setup

No login

Get Dynamically from ISP

Get Automatically

Use Default Address

 

WAN Setup

Only setting checked is Disable IGMP Proxying

1500 MTU size

 

LAN Setup

I am using Router as DHCP Server

 

When I check the Internet Port "Show Statistics" it shows the WAN and LAN ports as 100mbs/Full.

 

Any help please?

Thanks
