Did you come from stock and flashed DDWRT for the first time?
If so did you do :
Code:
nvram erase && reboot

from the CLI/putty?

What DDWRT build are you using (always state router and build number when posting)

Do you have Shortcut Forwarding Engine (SFE) enabled on Startup page?

Are you aware that the stock firmware has proprietary CTF (Cut Through Forwarding, a proprietary SFE) which is faster then DDWRT?

500M is the max on this router (1 Gig 2 core cpu)

SFE is a poor substitution for a fast CPU.
