I hope you guys can help me. I've just moved house and have set-up my computer and XBOX 360 today but the XBOX cannot see the PC.
Setup as follows: PC wired to ADSL router modem, XBOX wired to POWERLINE Acces point, 2nd POWERLINE Access point wired to ADSL router.
I managed to set up the extender by disabling the firewall and in fact all works fine with firewall disabled but as soon as firewall enabled, XBOX cannot see PC.
I have tried setting ports as described in www.microsoft.com/windowsxp/mediacenter/extender/setup/firewall/config.mspx
but this seems not to work. Can anyone give me an idea?
