Update - I'm not getting full speed from the Trendnet adapter. I'm on 3 Mbps DSL service, and routinely see 300 KBps downloads from a wired connection on this iBook. However wirelessly, with a signal strength of 2 or 3 out of 5 bars when connected to my 802.11g router, I'm only getting download speeds of 140 KBps. Still useable for most purposes (except video streaming), but was expecting better performance.
