No, nothing to do with WxC... They can access their emails, and I can connect via LogMeIn to their laptops. One of the laptops can browse websites, the other can't.
Strange though I can't, from their laptops, browse to 192.168.1.1 (their router). I'd like to reset it but can't do it now, for some reason (unless WxC has decided to disable all access to the router, which was enabled before?)
