I have 50 Mbps internet and i'm using E2500 with Firmware: DD-WRT v3.0-r27600 mega (08/11/15) just installed yesterday and it stuck at 37 Mbps. I already try to change channel, tx power but the result always the same, while my other router with stock firmware could reach 46 Mbps.

My setting is :

Wireless Mode AP
Wireless Network Mode N Only
Wireless Channel 1
Channel Width 20 Mhz
Sensitivity Range (ACK Timing) 50
Network ConfigurationUnbridged Bridged
Frame Burst Enable
Beacon Interval 50
DTIM Interval 5
TX Power 50
QOS Disable

Is there something wrong with my settings?

Which E2500 do you got?

V1 and V2 have a 300 Mhz CPU
V3 have a 500 Mhz.

Channel Width 20 Mhz. Increase to 40Mhz

What speed do you get on a wired client?

My E2500 is V3, i also try 40 Mhz and increase overclock to 400 but still no luck

With wired i could get 46 Mbps
