At work I share my internet connection with a G5 tower to my Macbook (I prefer to have my Mail sync with my personal computer and not with a machine anyone at the university can access). Anyway, whenever I reboot my macbook (which has been frequent, come on 10.4.8 ) I cannot for the life of me get the internet back up. It works fine before a reboot, I get blazin' fast internets - probably economy tubes. However, with a reboot I guess my tubes get all clogged and I can't get it to work again. Any advise to unclog the tubes?
