How to improve speed?

[Lessram]

using TP-Link 1043 v2.1 with Gargoyle 1.6.0
WiFi-N - 40Mhz (Channel 9+13)
Antenna's 9dBi (also TP-Link)
Signal strength is 100% / RSSI is 47
UTP Cable is CAT5e
Router gives max. rate 450Mbps
WiFi adapter (TP-Link WN823N) is ransmit rate 300Mbps
Connection to provider is 150Mbps
To test: distance to router is 2 meter
To test: Laptop is only device in network

Wired I get 130Mbps
Wireless I get 75-80Mbps

What can I do to get better a wireless speed?
I think I already done all.... but somehow it sticks at max. 80Mbps

Might stopping bwmon be a solution?

Code: Select all

 /etc/init.d/bwmon_gargoyle stop
 /etc/init.d/bwmon_gargoyle disable

(haven't tried it yet, because I don't know how to enable it again, afterward)

Or are there other options to try?

I gave it a try, assuming enabling code for wbmon would be logical.
So;

Code: Select all

/etc/init.d/bwmon_gargoyle stop
/etc/init.d/bwmon_gargoyle disable

would become;

Code: Select all

/etc/init.d/bwmon_gargoyle start
/etc/init.d/bwmon_gargoyle enable

After I gave the commands to stop/disable bwmon, I found out it really boosted the WiFi speed. from 75-80Mbps I now get 100-115Mbps
So a boost of about 30%

Even wired I get a boost
before: 130Mbps
after: 150Mbps (which is my providers max)

What is causing this? Is the CPU of the TP-Link 1043v2.1 too weak. Or is it a "problem" of the Gargoyle firmware?
