[MLB-WIRELESS] strange wireless problem with XP Pro

[Rowan Crowe]

Yep, I have the firewall disabled.

The first thing I did was uninstall Norton AV. I've heard it's hard to get
rid of this completely... I wonder if that has something to do with it?
Unfortunately I have to work backwards with this laptop - start with
everything preinstalled, then disable or uninstall what I don't want.

I initially thought it was an MTU/MSS problem but I can see that even 670
byte TCP packets are being "ignored" (if it was that problem then only
packets around 1460+ bytes would be an issue).

To summarise, the TCP connection succeeds and some data is transferred
(there doesn't seem to be a consistent amount), but after that XP seems to
be ignore inbound packets for that connection. If it was a firewalling
issue then I would expect the connection to fail from the start...

BTW can you ping an XP/SP2 computer? I never get any ping replies. I
presume they're blocked by default.

Cheers.
