My MBP is in the shop. I'd cloned it onto an external drive, which I'd hoped to use as the startup disk for a borrowed, nicer/newer MBP. Both computers run 10.5.8. The borrowed MBP gets onto Internet via my wi-fi, no problem, but if I start up from the external drive, it connects to the wifi but can't seem to actually get on the internet (even from right next to the router). Signal strength looks good. Yah, I unplugged the router for a couple mins and then repluggd it. No joy. Ideas?
