I find this really odd. I'm using Panther and the latest version of safari. I still have to upgrade to the latest version of firefox. Anyway, I find this really odd. At our office you can do either a wireless or ethernet connection to the internet. When I connect via wireless, I can't use firefox. It keeps asking me to configure the browser w/ a proxy. I've done this and I still can't connect. When I use the ethernet connection, I can't use safari--even if I change the proxy to the correct one. This isn't really urgent as I just switch between the two when I have to, but it's a wee bit annoying.
You may wanna get in touch with your Network Administrator for they might have specific settings for your office network.. I'm sure they can really help you with it
Have you tried setting your Mac's network preferences to 'Automatic?' System Preferences -> Network -> Location -> Automatic
XyNo - No I haven't tried that yet. I should though. But I have all the settings for the usual connection, and no one else I know who's using a mac in this windows dominated network is having my problems. booblanco - I have separate settings for the wireless (which is on Automatic) and the ethernet because they apparently use different proxy numbers. I don't know if having separate locations is the best way to do things.
