[ubuntu-us-mi] 802.11n wifi

[Robert Citek]

A friend of mine recently setup an 802.11n wifi network[1] in his
house using Ubuntu 8.10. However, instead of getting 300 Mbps or even
100 Mbps, his data rate is 54 Mpbs. Since this rate is no better than
802.11g, he was wondering is there something special he needs to do in
order to get 802.11n speeds.

Thanks in advance for any pointers.

does he have a 802.11n card in laptop? Are there other clients that are
connecting? Are they all 802.11n ?

if he doesn't have a card that supports 802.11n his speeds will be limited
to what it supports. If there are clients that are not 802.11n the router
will drop down to the lowest 802.11 client's settings.

Yes, both wifi card in machine (a desktop) and router are 802.11n.

There may be other clients on the network. Just to clarify, if a G or
B client is on the network, will the router drop down for just that
client or will it drop down for all clients?

It depends on the router. Some are capable of dual-broadcasting two network
types, while other are only capable of one.

What is the router model?

Which I assumes means that if the router is only capable of one, it
will drop all connections down to the lowest speed. Is that correct?

I do not know. I'll ask.

BTW, there are indeed other wifi clients (all G) on the network. So
my guess is that the router is single band and the other clients are
forcing the router to drop down to G speeds.

That is most likely correct.

My first thought is to ask if the wireless card in computer is also an N
card. The second thought is: are the drivers native Linux drivers?
Even if they are, they may just be copies of the 11g drivers without the
tweeks to enable the N.

Just thoughts,
Mark

Yes: card and router are N. No, non-native drivers. He has to use
ndiswrappers.
