This isn't directly unix-related, but I know a lot of you have more experience with wireless networking technologies than I do.
A friend of mine asked me to help troubleshoot his network. He is using several Cisco Aironet 350 bridges (100baseT/802.11b) to connect different network segments. There is frequently a lot of latency on the network, and the wireless links seem to be the bottleneck. The bridges report that they are operating at 11Mbit/s, and have 85% signal strength (and 95% signal quality). Yet transfer rates seem to be topping out at about 200KB/sec. Even allowing for a lot of protocol overhead, etc., that can't be more than about 2 Mbit/s. I'll probably get on the phone with Cisco tomorrow, but I wanted to get some real-world experience from the list. What kind of transfer rates can I realistically expect over an 802.11b link? Is the correlation between signal strength and throughput roughly linear or how does that work? Any general suggestions on how I might improve matters?
