[MLB-WIRELESS] strange wireless problem with XP Pro

[Daniel Whitehead]

Rowan,

If you have XP sp2 installed, the XP firewall will be turned on by default. 
to turn the XP firewall off, go control panel, network connections, right 
click on the LAN or WLAN interface that your are accessing the internet by, 
and go to the advanced tab, then click settings, and make sure u turn the XP 
firewall off. Install a 3rd party firewall, i find that the M$ firewall is 
Pox and not decent enough.


regards


Daniel Whitehead
