WPA & 802.11b

WPA & 802.11b

Post by blackba » Sat, 01 Jan 2005 23:20:50


Never owned a PDA before, thinking of buying a Dell Axim X30.



I have a Belkin FSD 7630 Wireless Router/ADSL modem.
My home PCs use 802.11g & WPA although router is set to mixed 802.11b
& 802.11g




I'm hoping the Dell PDA will 'see' the 802.11b whilst the rest of my
house uses 802.11g.
Seen a lot on this & other sites about WPA problems.
I've read that Pocket pc 2003 SE supports WPA.
If the wifi won't work I'd sooner buy a cheaper non wifi PDA.



Will my existing WPA network prevent the PDA connecting to router via
802.11b?

Anyone using similar mixed 802.11b & 802.11g set-up with WPA?

WPA & 802.11b

I have the Axim X-30 and it works flawlessley with my AP at work - a Proxim
Orinoco AP600 with WPA. I have both B & G clients connecting to it.

Basically, You should have no problem with newer equipment. However with
older equipment it is far more problematic.

At home I have both an older Dlink 614+ and a Netgear 614, both of which I
upgraded the firmware on, and neither one of these work with the Axim with
WPA. (WEP is no problem on either router though) The problem is not with
the Axim, as far as I can tell. The Axim will not connect with the Dlink
router AT ALL with WPA but my netgear WG511T PCCARD will.

OTHO both my laptop and Axim will connect to the Netgear router, but almost
immediately it (the router) will go into a cycle of constantly rebooting,

Bottom line though is that I think WPA was an after thought with BOTH these
early models of these routers (before WPA was ratified) and will NEVER play
well with WPA...

That being said, I recently helped a co-worker go wireless with a Netgear
WGT624, and it worked well with both my "B" Axim and his "G" laptop
connected (at the same time) with WPA.

So... It _SHOULD_ work with your Belkin, but you can never be 100%

As they say YMMV!!

Good luck

Aaron

P.S. I REALLY like my AXIM - well worth the money!

Thanks for a useful and in-depth reply. Looks like I'll take a chance
then.

Funny, I've always thought of PDAs as technology for technology's
sake, now I've convinced myself I can't live without one...basically I
love gadgets.

Incidentally, how old are the Dlink 614+ and Netgear 614?

FWIW...I use WPA-PSK (TKIP) on an iPAQ 5555 and a Buffalo WBR-G54. It works very well in my case.

Keep in mind that if an 802.11b device connects to an 802.11g/b network running in mixed mode,
802.11g clients will drop down to the 802.11b speed until the 802.11b only client disconnects...

Really? All clients drop down to 802.11b speed when a single b device is
connected... I had no idea. I've heard of schools and companies turning off
b access and had no idea why they would do that, but that all makes sense
now. That's just crazy, why would the router have to drop everyone to slower
speeds?

That's the case for most, if not all consumer grade 802.11g access points. I believe some higher
priced access points may be able to run in a true dual mode but have no personal experience with
them..

I beleive that my Orinoco Proxim AP600 does dual mode, (but don't quote me
;-).

Anyway, at home I've never really noticed a difference in terms of speed
when I have both devices connected (my "G" laptop and my "B" Axim). That
being said, I'm sure I _might_ notice a difference if I were trying to
transfer a large file from my PC to the laptop and had the Axim connected,
but for the most part I don't really think you would see any degradation of
speed for WEB based stuff (i.e. streaming shows, mp3's etc) as my 1.5 DSL
doesn't even get close to filling the pipe, even for the11 mb per sec of the
"B" devices).

More 'n likely if I were transfering a file that big anyway, I would just
plug a CAT 5 cable directly into the router to get a full 100 MB connection
to the network (at least untill I get the WGT624 router <GRIN>)

I also get around the problem by having both routers connected (I simply use
one as an AP rather that a router) so that my laptop connects to the Netgear
router in "G" mode and the Axim connects to the Dlink in "B" mode, so the
one doesn't slow the other down.

I will also set it up the same way when I get the Netgear 624 (hopefully
soon, as I have the 108mb Netgear 511T card for my laptop, which will ONLY
go up to 54Mb while connected to the Netgear 614).




The Dlink is about 2 years old (I think), and the Netgear (which I bought
used from a friend who wanted to u/g) I've had for about a year (it is the
ver.1 and probably came out closer to 2 yeas ago i'm guessing - it was
definitely before WPA was ratified I think and is part of the problem of why
WPA doesn't work very well on either of these routers.).

I may be way off on the age, but it SEEMS like I've had both of these
routers forever now! Definitely time to buy a shiny new one to play with!!

've done some tests with my linksys ap's in mixed mode and I didn't notice
any speed decrease. To test I put my ap in mixed mode, then transfered a 1
gig file over the network and while the file was transfering I turned on my
pocket pc and tranfered another file over the network to the device. I did
notice a small dip in the transfer rate to my laptop 1.2Mb/s -> 1.1Mb/s but
that was about it. I have seen other ap's have horrible times when a "B"
client connected in mixed mode so as always YMMV.

Eric,

Thanks...

My middle step-son recently installed a Linksys WRT-54G so it will be interesting to experiment a
bit when I visit him next. He has an 802.11g equipped laptop. I don't have a way to test this
802.11g vs 802.11b drop off on my home LAN simply because my iPAQ 5555 is my only wireless client...

Later...

Ahhh, the wrt54g have the same hardware as the wap54g so that should be a
good test.
