■ Speed of connection: The 802.11b and 802.11g standards will
| automatically choose the best speed depending on the quality of your |
| connection. As the signal quality weakens then the speed falls back to |
| a lower speed. The speeds supported by 802.11g are 54 Mbps, |
| 48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps, and 6 Mbps. The |
| speeds supported by 802.11b are 11 Mbps, 5.5 Mbps, 2 Mbps and |
| 1 Mbps. In general the closer you are to the Gateway the better the |
| speed. If you are not achieving the speed you had anticipated then try |
| moving the antenna on the Gateway or moving the Wireless |
| computer closer to the Gateway. In an ideal network the Gateway |
| should be located in the centre of the network with Wireless |
| computers distributed around it. Applications are generally available |
| with the computer wireless card to carry out a site survey. Use this |
| application to find the optimal siting for your wireless computer. |
| Consult your Computer Card documentation and vendor for more |
| details. |
