Internet sharing is slow / not working at all

Question

Hello everybody and everyone.
Something strage has happend with my Internet Sharing.. I discovered it for me since a week. So, I made the whole thing in the Preferences bla-bla-bla.. A week or even more it was working. (I'm using my iPod with the Wi-fi from my iMac. And iMac becomes it from Ethernet) So, it worked perfectly.. But now my iPad see it, use it, but if I want to look a movie or something like that (it worked, actually) he just stops. Internet surfing is every time like "10min pause, then JUMP...another 10 min pause".
Internet on my iMac still be perfect. So thats not a problem. When I click on my sharing WiFi, it shows me something like "The connection with "(null)" is failed. By the connection the timeout is occurred" (sorry for my english, actually I use a German language on my Mac, so if somebody knows it: "Die Verbindung mit „(null)“ ist fehlgeschlagen. Bei der Verbindung ist eine Zeitüberschreitung aufgetreten.")
I tried to change passwords / chanells / name, but nothing help. It gives some "push" for 5 seconds of internet-happiness and then starts this crap again.
To make a long story short: I'm sharing wifi from my iMac, iPod catches it, but when I open a web-site, he can use wifi anymore.
Thanks for help, sorry if it was too long

Mark, this is not the same as Robert Cole's problem. He's talking about Internet sharing -- sharing his Mac's connection to the Internet with other computers. You're talking about Web sharing -- sharing files on your Mac with others via the Web.
Robert, I haven't had success with this yet, either -- but I've only tried it once, and didn't have the opportunity to fiddle. I would try -- in order --
turning off the FireWall on the G5;
going into Network Preferences > Airport > TCP/IP on the iBook, and listing your G5's Airport IP-address as the default router. While you're there, make sure your iBook has an Airport IP-address that's different than the G5's, but on the same subnet (differing only in the last number).
If #2 works, you can probably turn the firewall on your G5 back on.
Post back & let me know how it goes!
