I've had similar problems with my TiBook 15" 800 MHz. Sometimes I'll lose the signal strength completely. If that happens during a mail check or a Slashdock update, the system slows to a crawl and the CPU usage goes through the ceiling. If I put the book to sleep and wake it up again, the problem of slowdown is usually resolved and the signal strength returns to its normal 3 or 4 bars.
