Whenever I have my external seagate goflex drive hooked up via firewire, my macbook pro shows being connected to wifi but refuses to load any webpages. Even if I just eject/unmount the drive it's the same thing, but as soon as I physically remove and disconnect the drive the internet connection works again immediately. If I hook up the drive via USB, no issues. I went into the network preferences and selected set service order and removed/moved firewire down the list and wifi to the top above firewire. Still the same issue.
Any help here guys? No idea what to do here.
Sounds like it's trying to use the GoFlex as an internet device when it's connected via FW. Go to Network in System Preferences when the drive is connected via FW, see if it's saying anything in the Status window. If it is, click on the gear on the bottom left, and click "make service inactive". Hopefully that doesn't kill the drive storage device aspect of it. It might.
FW is also a network protocol, not just for connecting drives. However generally it shouldn't try to act as the sole interface, particularly if the drive obviously isn't dishing out valid IP information. I've never seen this happen, personally, and I use a lot of FW drives.
