Hi there,
I have RB433AH with R52H card using b/g mode and 16dbi omni directional antenna with 20 clients connected to it.
What is the best speed i can acheave and is there a way to improve it with a new wireless card?

Clients are nanostation loco 2 and Edimax access points with Grid antennas.

Currently i can acheave a maximum of 11mbits...but it is not enough.
I need at least 20mbits for the moment. I want to evade placing other APs right now so i look for some improvement.
Cant use 2.4ghz-turbo and nstreme becouse of the clients devices.

Any suggestions?

Regards, Ventsi.

Nstreme is good for point-to-point links.
Reality doesn't care for your needs.
Change the omni antenna to some directional antennas (sectors), seperate wireless interfaces each. Will work just fine, if configured right. Don't use b/g, use g.

Hahahah,
Reality really doesn't care

I will install in addition some Nano M2
Just was curious if i can reach better speed.
Thanks anyways.

And btw...why is better to use g only?

You try talking to two people simultaniously in two different languages!

If they support 802.11G and have connected via G mode, they should get around 30Mbit, if you have good signal.

Hmmm...thanks Normis... i will change it to G mode and will post later the result.

Hmmm...no improvement.
It seems that the best outgoing traffic from the wireless card is 11-12 mbits.
It is strange as i remember 4-5 years ago i used 2x Edimax APs on 5km link and managed to pass 16mbits ptp...i hope that the CPU of the board will handle the same traffic or better

Anyways, thanks for the help.
I am gonna place another AP

what is the signal level on both ends ?

It is PtMP link.
There are around 22*2= 44 ends
