broadcom bcm943224 unable to connect at n speed

I have a bcm943224 duel ban 2.4-5GHz a-b-g-n card in my Dell Latitude e6400 I connect to my router with a Netgear WNDAP330 wireless bridge. I am using the Broadcom-wl driver and kernel. When I connect using 2.4GHz it connects using G ban only and runs at 54mgbits and when on 5Ghz I get up to 200mgbits but only A ban… I have also tried an Atheros duel ban a-b-g-n card with similar sec’s with similar results*.*
Any Ideas why the card does not see my N ban or is this a limitation of the Broadcom driver.
I am running opensuse 12.3 64 bit

The driver you are using is closed source, i.e. none of us has any chance to see
what it is doing. When you choose, or need to, use such a driver, you are stuck
with the results.

If I understand you correctly, you say that an Atheros dual-band card is also
limited to 54 Mbps. If that is true, then it may be that your AP is not
configured correctly.

Actually The Atheros (WPEAN-127N) gets great speed some time up to 200mbps on 5GHz A-ban it just does not see my N ban only the G-ban on 2.4 or A-ban on 5GHz router. As for the Broadcom card I also tried the kernel driver but it did not work at all, and the B43 driver and firmware is only able to see the 2.4 GHz radio.
I guess my question should be is there any cards that can connect on the N-ban ether on 2.4 or 5GHz network. All of the cards I’ve tried so far seem to only see the A or G-bans. Ateros with ATH9k driver Intel with iwl3945 driver.

Sorry if this seems rambling but this is my first time on the forums and I’m not quite sure how it all works yet.

First of all, the term is band, not ban. There is no way you can tell the
capability other than by looking at the connection speed, throughput, or the
configuration page of the AP. For example, two of my APs are shown below:

The AP for cell 3 has 802.11bgn capability and is capable of 300 Mbps in the 2.4
GHz band. All wifi communication is limited to 1/2 the raw rate and I have
seen 70 Mbps throughput with it, whereas cell 5 is capable of 802.11g only, or
54 Mbps. To my eye, there is little difference is the scan data. As I said
above, only via throughput measurements or from the configuration page of the AP
is the result known.

Throughput is measured using a program such as iperf with a server connected by
wire to the AP/router.

Thanks for your patience with my poor spelling. Could you please post the code you used to get the read out you posted. I used (sudo /usr/sbin/iwlist scan) but it gave some what different read out.

If I look in network manger when connected to 5GHz it is A and on 2.4GHz it is G my card is an A-B-G-N card is there a way to choose a band? Thanks

This one is in the 5 GHz band; however, it is weak.

You should use the code tags to enter computer data. The way you posted, this
entry was code wrapped and I missed it at first.

This one is also in the 5 GHz band, but is a lot stronger.

You choose the band based on the AP that you select. Why are there two different
5 GHz APs with the same ESSID? Is this at work and they expect roaming?

If you have a choice of 2.4 or 5 GHz bands, you should choose the 5 GHz band.
Not only is it less crowded, but it will penetrate walls better and give you
higher throughput.

I was unable to figure out where the code post function was as I am new to posting, I will figure it out. Cell 1 is my base station down the street at my office about 1000’ and cell 2 is the end point of my bridge at home where I use my laptop. I saw the roaming line in the code and wondered what it was. It should not be expecting me to roam. I have the 2.4 GHz radio on my bridge turned off and use the 5GHz for the better through put. The bridge I have is capable of up to 500mbps but not on A band. Thus my dilemma as my card has N band but does not seem to want to use it.

Well it seems I may have just found the answer to my problem. I found a post on an other forum.
**(Change default channel width of router - **The higher speeds of wireless N and AC can only be achieved by using the 40MHz wide channels. For wireless N (and possibly wireless AC), the default channel-width set on routers is only 20MHz. But you can login to the control panel of the router and in the wireless settings change the channel-width to auto 20/40MHz.)
I have my bridge set to auto 20/40 I am going to change this tomorrow to 40MHz and see what happens.

It is true you need to use 40 MHz channels to achieve the highest throughput.
With a 1x1 (1 transmitter, 1 receiver) configuration, the maximum is 150 Mbps.
You need a 2x2 configuration for 300 Mbps.

One other thing, using a wireless repeater, which is what I think you mean when
you say “bridge”, you will cut the rate in half as the repeater has 2x the
amount of work to do, and wifi is half duplex.

Having the repeater set to “auto 20/40” should be the correct setting otherwise,
it will never transmit 20 MHz channels.

The repeater I have is a commercial grade unit very hi power. When I connect hard wired at the end point the through put is around 400mbps or more. On the 5GHz band there is no dynamic channel setting it must be to a specific channel, I’m assuming I can pick one that is 40Mhz.

How do you measure throughput? Please document that 400 Mbps.

No wireless connection short of 802.11ac can possibly attain rates that high as
that. For 802.11n, your 43224 has a 2x2 configuration, thus a raw rate of 300
Mbps (Mega bps) is possible. As I have explained, any one station will never
reach more than 1/2 that value due to the half-duplex nature of the
communication. Furthermore, the repeater will further cut the rate in half. I
would not expect you to get more than 75 Mbps throughput. I have no idea what
mbps (milli bps) means.

The originating AP, not the repeater, sets the parameters. Think of it as a
mirror - it passes on what it actually receives, not what you want.
