problems with WPA | Linksys 802..11b wireless

Archived from groups: alt.internet.wireless (More info?)

Greetings -

I've been happily using my LinkSys 802.11b wireless router (BEFW11S4),
with my laptop (running WinXP SP1), which has a WPC11 v4 wireless card
- but, using WEP encryption.

Fora bunch of reasons (most having to do with a desire to increase my
system security), I decided to try 'upgrading' to WPA (using PSK).
However, I've had no luck at all - if I set up the router for DHCP, my
laptop doesn't pick up an IP number. If I try a fixed IP address, I
can connect to the router, but I can't get out to the internet.

I've done all the usual things (upgrade drivers, confirm WPA patch for
WinXP installed, etc), but no luck.

What I find really puzzling is that WEP works perfectly. I've followed
the WPA instructions step for step, based on a lot of articles I've
read, and yet I'm still having no luck with it.

I'm guessing this is a fairly common problem, and am hoping there are
some common fixes out there.

Suggestions?

    I'm using the exact same hardware and had the same problem. Iposted
    here before you did and have had no responces. Hope you have better
    luck than I have.

    You may want to try switching network protocols over to NWlink IPX/SPX
    instead of NetBEUI and see if that buys you anything.

    It's a shot.

    If I get anything helpful via private email, I'll post it here.

    Of course, LinkSys 'tech support' was singularly unhelpfull -
    everything 'works' at their end.

    Of course ;-)

    I can see that NetBEUI and IPX will allow you to communicate on your LAN
    without the need for an IP address, but none of these protocols are
    involved in the process of obtaining an IP address. That is done with
    broadcasts, which is just a simple ethernet frame.

    You are certainly correct that NetBEUI and IPX are not involved with
    obtaining an IP address. But obtaining one isn't an Ethernet function. An
    Ethernet frame addressed to the broadcast MAC address (ff-ff-ff-ff-ff-ff)
    carries an IP packet addressed to the limited broadcast address
    (255.255.255.255), which carries a UDP segment addressed to the BOOTP port,
    which carries a DHCP message containing the request for IP address
    assignment.

    I'm sure that is very correct, as some IP info would have to be in there
    somewhere to indicate port 67...

    The Linksys router model number BEFW11S4 you mentioned in your post is
    not capable of using the WPA standard.

    Don't confuse "Open", "Shared" and "Auto" for the authentication type
    with "Pre-shared key" for encryption. It's two entirely different
    things.
