I have DirecWay satellite hook up for internet on the Ethernet port on a G3/upgraded to G4. I have a Linksys Wireless G router hooked to it and a Tibook 400 with an Airport card. I have been able to do wireless printing and access the other Mac's hard drive all through the network. The Tibook has 10.3.4 and the other Mac had 10.3.2. I upgraded it to also be running 10.3.4 and now I cannot network them any longer. The printer is gone and I can't access either hard drive from the opposing computer like I could before. Yet the Tibook has wireless internet access so there is a connection somehow. Arrgh this is driving me crazy, I have looked everywhere. Why would this change? Something obvious I'm overlooking. I also repaired permissions, logged in and out and restarted. I give for the night.<br><br>

Was the firewall turned on when you upgraded?<br><br><br>

so what IP addresses do each have?<br><br>both can access the internet?<br><br>have yu rebooted the router and have it release all DHCP leases?<br><br>You cant polish a Turd.

They each have a different one.<br>Both can get online.<br><br>When I first hooked it up it required nothing to get online. I hooked it up opened up Airport & Voila. I turned on shared printing and remote access everything worked well. So I decided to go one step farther since it was going so good and upgrade Rick's software. Of course that's when it really screws up.<br>Anyhoo I perused the settings and finally just poked the reset button since it was never set to anything custom anyway. Boom I am back to working again. Printer back access back dog back pickup back, wait that's a drinkin' song.<br>Thanks for the reset idea nutty it was something obvious.<br>Is this a bad thing? I had to go for it to access the file sharing.<br><br><br>

That's ok since you are behind a router, but you shouldn't need to turn that on anyway. That is making your Mac act as another router. As long as your router is in b *and* g mode, all of your computers should get their IP addresses from the router.<br><br><br>

Thanks I see what you mean. I turned it off.<br><br>
