Getting only b speeds

I received a TrueMobile 1300 PCMCIA card with my Dell computer and I
purchased a LinkSys PCI adapter, model WMP54G. Both say they will work with
the g standard, and both are 2.4GHZ. I have them set in a Ad Hoc mode, and
have the option set on the software for the LinkSys card to only allow G
devices to connect to the network. However, I am only getting 11Mbs speeds.
I believe the G standard is 54Mbs.
I was reading that to get the 54 speed though, the card had to run at
5GHz, not 2.4. So I am a little confused. Would this mean the cards are
only g compatible, but not run at g speeds? Can the card say 2.4Ghz and
still run at the 54Mbs?

Thanks

whatever speed/standard, you will never achieve the full speed, always go
half so G will give you 54Mbs so 27Mbs and B will give you 11Mbs so 5.5Mbs
etc

802.11a supports a maximum of 54Mbps at 5Ghz. 802.11g supports 54Mbps at
2.4Ghz. There is a difference between nominal bitrate and actual throughput.
Nominal bitrate must be one of a fixed set of values that are negotiated
when a client joins a network. Actual throughput is the real rate at which
data flows, which is always less than the negotiated, or nominal, bitrate.

For 802.11g, the nominal rates are (in Mbps): 54, 48, 36, 24, 18, 12, 9, 6.
For 802.11b, the rates are 11, 5.5, 2, 1. 802.11g includes 802.11b for
interoperating with 802.11b devices. The 802.11g rate sequence uses a
different encoding technique from the 802.11b sequence. If a network
contains only 802.11g devices, the bitrates 11, 5.5, 2, and 1 will never
occur. The bitrate might degrade due to poor signal quality, interference,
or just too much contention from too many stations, but it will degrade
through the sequence of values 12, 9, 6 if there are only 802.11g devices.

The "speed" setting you read from the Windows connection icon (or the
manufacturer's connection management utility) is usually the negotiated
bitrate, not the throughput. This will always be a number from one of the
lists cited above. If you are seeing 11Mbps, then your two devices have
established an 802.11b network. Evidently, you have not succeeded in
restricting one or both devices to 802.11g only. Or, is it possible that
some other 802.11b device has connected to your ad-hoc network?

Thanks for the information. This gives me a bit more to chew on. I
thought there was something wrong somewhere. My quess would be the
TrueMobile card. I'll need to email both companies and see what they say.

It really sounds like a simple configuration issue. Both client adapters
need to be set to avoid the 802.11b bitrates. I have DLink equipment, so my
config menus are different from yours, but something similar should be
available to you. In my case, using the DLink config utility configuration
tab, there is a set of selectable bands. If I select 11B, the client
connects at 11Mbps. If I select 11G and deselect 11B, the client connects at
54Mbps and will never attempt 11 Mbps.

If you are using Windows zero config, I recommend using the vendor config
utilities instead (disable Windows zero config). Windows config doesn't
always allow access to all the configurable properties of the device. If
there is a way to use WZC to restrict rate negotiation, I haven't found it.

Out of interest, if I have a G card but its at the limit of the range,
quite few brick walls to go through. Is it better that I use B protocol
or will the lowest G rate of 6 work when the lowest B rate of between 1
and 2 is just sufficient?

Good question. I don't know. I'd guess that you'd do better at extreme range
by choosing to be 802.11b and going down to 1 Mbps - but that's just a
guess. If you have both 802.11b and 802.11g modes enabled, I expect most
cards would automatically switch to 802.11b encoding and bitrates below 6
Mbps.
