wireless N speed

[kruijf]

My wireless give me a 72 Mb/s connection speed, but i'm using wireless N.
The speed must be 150 Mb/s or higher, how can i speed up the connection speed?.

Does you ISP even supply that high of a bandwidth? If not, then no.

[kruijf]

Yes they supply that, friends of me have 150 Mb/s speed.
They have the same ISP as me, onley they use Windows 7.

What's the max speed when you are directly connected to the modem via a DSL line? Can you go to www.speedtest.net and verify you speed?

[kruijf]

I'm talking about the connection of my laptop whit my acces point, not my internet speed.
But now i know my internet speed is not correct also i must have 100mb up and down, and it is now 30mb up and down.

If you have a 150 Mbps connection, the 150 speed is only theoretical. The true speed will always be slower - and you will only near 150 when you are very close to the access point or router. 72 Mbps wireless-N is not bad if there is a wall in-between.

Maybe you can get higher speeds with computers that have a 300 Mbps wifi card. If the signal is so bad that you have only half speed, a 150 Mbps wifi card will have 75 Mbps signal while a 300 one will have 150 Mbps signal. At least, if your router supports the 300 Mbps 802.11n standard.

Ok its not bad thats true, but there is no wall.

What wifi card do you have? Please run inxi -N in terminal and post the output.

[kruijf]

Here is the output

Code: Select all

inxi -N
Network:   Card-1: Realtek RTL8188CE 802.11b/g/n WiFi Adapter driver: rtl8192ce 
           Card-2: Atheros AR8152 v2.0 Fast Ethernet driver: atl1c 

[AlbertP]

Ok, you have Realtek RTL8188CE wifi. That's only a 150Mbps card, meaning the actual speed will always be lower than 150Mbps.

Maybe speed can be improved by installing an updated driver. Please download compat-wireless-2.6.tar.bz2 from here: http://linuxwireless.org/en/users/Downl ... he_tarball
After unpacking the downloaded file, please go to the folder where you unpacked it, and run this in terminal:

Code: Select all

./scripts/driver-select rtlwifi
make
sudo make install

Then please reboot and go to speedtest.net again.

[kruijf]

The speed is the same as before.
