I have got a new internet connection which is at 50Mbps. The previous one was at 6M. I have this problem now where i can't get more than around 15M. My wifi card is the RTL8187 onboard of the "asus p5k premium wifi", which according to specification says it supports 54M. I have installed the driver through the package "firmware-realtek". I use Debian with KDE.
When i run iwconfig i get:
wlx0015af3e89a2 IEEE 802.11 ESSID:"Digicom -Inva"
Mode:Managed Frequency:2.432 GHz Access Point: C8:3A:35:B0:4D:F0

It says 9Mbps even though i get around 15. On a laptop it says 144Mbps and i get good speed with the same connection. So i figure it must be my wireless card at fault but when i try to increase it,
sudo iwconfig wlx0015af3e89a2 rate 54M
It does nothing and remains the same
sudo iwconfig wlx0015af3e89a2 commit

Is there anything i can do to max it out?
One more thing, i dont know if this means anything, but i was unable to connect to this network using /etc/network/interfaces, as i was connecting to my previous modem. I resorted to using wicd (the only thing that worked) because plasma-nm was not working either.
auto lo iface lo inet loopback
iface wlx0015af3e89a2 inet dhcp
# this below works fine
