Below is the router I use. Works great, I use the syslog feature for managing an alarm system, very handy, however I pay xfinity for 200Mbs, but I can only render 100Mbs. I recently plugged my windows box's ethernet connection to the cable modem and rendered 225Mbps. Then I plugged only this windows box to the E3000 router and the only other E3000 connection was between the WAN port and the cable modem. I can only render 100Mbs. How can I troubleshoot this ? The E3000 has wifi off.
Thanks

PS Upgraded to latest DD-WRT v3.0-r44715 mega (11/03/20) - same 1/2 speed result.

you seem like a classic case Razz
-first.. see the forum guidelines with helpful pointers about how to research your router, where and what firmware to download, where and how to post and many other helpful tips:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=324087

-than update to a newer build as the one you run is old and not recommended
-last builds here https://download1.dd-wrt.com/dd-wrtv2/downloads/betas/2023/

In general routers have a different classes..and specs..low specs routers cant do much
for better speeds its always recommended better routers...
many posts on your subject...
with 2 words when you update...reset after the update and rebuild your settings manually...
Than try, on basic config page there is a section called Shortcut Forwarding Engine (next to MTU). enable it save and reboot and check your speed again...if this helps...

dont forget to read the guidelines !!

Upgrade to K3X, enable CTF option under Shortcut Forwarding Engine (unless you use port forwarding of any sort). Current release is 52720.
