1-This forum is about iBooks, NOT PowerBooks
2-Your issue is with wireless networking; there's a Networking forum where your question should actually be posted.
3-Learn to use capitalization and sentence structure, or your message will be lost because people will not bother to read what you write.
Post this (rewritten so people can reas it) in Networking, and include which model of PowerBook you have. The titanium-cased PowerBooks had well-known wireless range issues, but the aluminum-cased books have gotten much better.
