Let's say someone has nothing but 802.11b in said wifi network with 6 units. Remember that wifi is half-duplex at best speed of 11 megabit. If someone is a bit further out, their connection may degrade the network to about 1 megabit and then that is split 6 ways.
All this is nice and all, but the fix is to upgrade the WAP to 802.11g, lock out 802.11b use and it will get better. However, one P2P user and everyone suffers again.
In closing, the "workgroup" display in windows was not a good test of how many users are on the wifi network.
I live in an apartment complex that has 6 units. They provide free wireless internet for us. Im not exactly sure what service it is but i think its satelittle from direcway, but I could be wrong. Anyways I connect at 11 Mbps and get a good, to very good signal 99% of the time. The thing is it that it is so slow. I feel like im surfing the web on 56K dialup. What could be making it so slow? i checked the workgroup and theres only 1 only computer connected, so i doubt it could be using all the bandwith. Any ideas what I can do to improve speed?
