Haven't tried that SD in truth, will give it a go tomorrow. RGB, only windows firewall, which prior to the new router had no bearing on the issue, so I discounted it as the cause, but tried it with the firewall off too & no joy.
Under wpa, telnet reported local host unreachable, wpa off & it connects. As an aside, telnet is not switched on in windows 7, you have to add it from the control panel.
