Put my G4 running 10.1.5 in the closet for 6 mo. after I got a G5. G4 had no problem accessing the internet before I put it away- now it can't, even when I plug it directly into the DSL modem. Something I tried gave me an error msg that it had no dial tone. The G5 has no trouble connecting. Any ideas? If it's OS related I got Tiger ready to go, but it says I should update the firmware before installing- and I can't access the internet
