BIPAC 5200G router firmware query.

[BOAC]

I 'helpfully'(!) 'upgraded' no2 son's desktop to XP PRO SP3 from SP2 during a virus clean and now find his Bipac 5200G router has dumped the wired desktop connection. Firmware update required and waiting to go on - Billion Products for SSL VPN, ADSL Modem/Router, Wireless ADSL Router, Powerline ADSL Router and Adapter, VoIP ADSL Modem/Router, Security Router, Broadband Router, SHDSL Bridge/Router, iBusiness Security, ISDN Product has the info. I understand it was poor 'non-compliant' firmware coding by BIPAC that caused the issue.

I can crack that - BUT - he also runs a laptop with Vista on Wireless on the BIPAC router which does connect ok on the 'bad' firmware. Anyone know if the upgrade will still allow the Vista wifi connection? I cannot see anything definitive on the BIPAC site.
