Linksys WRT54GS wireless router occasionally drops to 1.0 Mbps and stays there.

Sorry. The names are sufficiently similar that I often get them confused.

Very cool. That would give me a tool to test for local interference at one end of a wireless link without sniffing the traffic. If a client receiver is hearing RF junk from a local source of interference, the data rate from the wireless access point to the local receiver will probably be much lower in that direction. In the other direction, where the receiver does not hear any interference, the data rate will be higher. Acer, err... Asus, did that one correctly.
