How to pull RT68 WAN interface Stats

[puyallup]

I'm looking for some help troubleshooting any issue I'm having with the WAN interface on my RT68U. Is there a telnet command to pull WAN interface stats? Possible CRC errors or anything like that.

I have a Comcast Gig and I have notice that after either rebooting my Router or Cable Modem or disconnecting the cable between them for a couple of seconds and putting it back I get full gig speed (900ish) I'm expecting at any time of the day or night. However after several hours those speed slow to 500 - 600ish Mb. So I'm trying to determine the root cause.

All the setting on the router should be correct:
1. Reset to default and reconfigured the router
2. Disabled QOS
3. Disabled Span Tree
4. Enabled CTF/FA

I have tried different cable modems: MB8600 and CM1000 hoping that it might be an issue with the Gig interface on that side. At this point hoping I can find some clues thru the router stats before I look at replacing the router altogether.

Try using ifconfig on your WAN interface (it's either eth0 or vlan2).

Look for errors on RX/TX packets or collisions.

admin@RT-AC68U:/tmp/home/root# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 30:5A:3A:C7:8A:20
          inet addr:82.22.119.92  Bcast:82.22.119.255  Mask:255.255.252.0
          inet6 addr: fe80::325a:3aff:fec7:8a20/64 Scope:Link

Thanks ColinTaylor, exactly what I was looking for!
