I'm hoping someone might be able to help with this problem...

I'm trying to set up a wireless network for my laptop (Dell Inspiron 1300
running XP Home SP2) and my desktop PC (generic, also running XP Home SP2).
I've got a SafeCom SWBAR-5400 router, which is linked by ethernet cable to
the desktop.

I started by setting up a fully wired network, using a cable from the laptop
to the router. All was fine - shares worked in both directions, and both
computers accessed the internet ok (through a cable modem attached to the
router). But now that I've changed over to the wireless connection, I can't
ping the laptop from the desktop by name any more; and almost never by IP
address (the laptop replies to about one packet in eight). It all works fine
in the other direction: I can ping reliably from laptop to desktop, and
access files on the desktop. Internet access from both computers is still ok,
if a bit slow from the laptop.

I've tried some of the fixes mentioned in this newsgroup and elsewhere, but
without success. If anyone's got any suggestions, I'd be grateful.

I'll include ipconfig outputs below. First is the laptop ("Inspiron"). Next
is the desktop ("Prx").

Here are the outputs I get from ping attempts:

C:\>ping Inspiron
Ping request could not find host Inspiron. Please check the name and try
again.

C:\>ping 192.168.123.123

Pinging 192.168.123.123 with 32 bytes of data:

Reply from 192.168.123.123: bytes=32 time=11ms TTL=128

Thanks.

Caolas,

Are the Intel drivers on Inspiron up to date? I'd start by checking that.
Then, I'd look at LSP / Winsock corruption.
