Part 2 - computer up and running - NO internet - help! :(
Got the eMac back up and running.
No internet connectivity on the eMac yet
Right clicked on the airport icon at the top right of the desktop.
Selected the correct network name, say "home".
Entered the encryption key, 128 bit hex code (40 characters) that the router is setup to use.
Checked status of Airport:
Signal level: 12 bars out of 15 bars highlited. Good signal level.
Opened up Safari but it cannot open default url "livepage.apple.com"
Tried opening"www.hotmail.com" , also failed
This is really an airport question. If possible you should change the title.
Can't remember if you can do that as an edit or if the moderator has to do it.
For me it has been almost 3 years since I had the grief of dealing with wireless so I will defer to more qualified members for an answer. I vaguely recall clearing all the settings (including keychain) and starting the set-up from scratch but cannot remember any details at all. Sorry.

256meg ram (slot 1), slot 0 is empty
56K modem? but no modem listed in hardware setup listing when running hardware diagnostics.
OS X is really working your hard drive with only 256 MB of RAM. You need at least 512 to run it properly, and I would go for a 1 Gig. Otherwise, every once in a while it will have a memory crash like the one you had.
It may have damaged your directory, so next time you boot, hold down option-S for single user, wait for all the UNIX to finish and type fsck -fy
There is a space after the fsck.
If it makes changes, type it again. Then when its done, type reboot.
Then go get some RAM. Tiger (I'm assuming) is very stable on G4's when you have the memory, it was Intel that it had some bugs on. Leopard has fixed those.
As for the connectivity, I would run the assistant. Not sure if its your network prefs or the airport. You could find your airport plist file and delete it and redo the network settings. Unplug the router and plug it in again. Etc.
