This I took into account when designing the link and estimating the throughput. I have decided that the cost (time and energy) in cracking into the network is far below the value of the data sent over it. I run firewalls at either end effectively securing my important data. With an FTP server (ProFTPd) at one end.
If someone got into the network they would then have to sniff a password for an ftp account, then that would only give them access to that one account which is chrooted on a secured linux box. The data is not that important, in fact it is now MORE secure, previously data was couriered across town on CD rom, these where then thrown in the bin, if a criminal wanted the data they could just have searched the bins. It is easier most of the time to break into a company, insert a wireless hub right on there network (In the roof somewhere) and hack away that way. Photocopy repair, Telephone repair, Sight Survey, Suspected leaky roof. Who would know??? I am just an IT consultant working in the Bristol area, I got onto the BAWUG list cause I liked what they where doing and would like to start something similar. These networks will hopefully become a lot more common and ISP / Bandwidth vendors will start to open there eyes to cheep "Last mile" connectivity that these solutions can offer. Regards Richy P.S.

I just wanted to ask you if you work in the WiFi field, I am graduating from Uni this summer and was hoping to get into this as a career. My dissertation is WLAN Security, I noticed you have locked MACs and are using a filter, but a hacker can flash his products MAC to be the same as either of yours if he is skilled and really can be arsed to (he would get ur MAC from the association probe response of one of the APs - even if SSID broadcast is disabled). Nice one on the link, why did you do it? And how much did the project cost?

Thanks My Setup I have 2x Buffalo 54G access points (1 each side). The one my side is sat in a Tupperware box (Clear Lunchbox, lol) on our roof attached to the antenna mast with a hyperlink 15db high gain mini grid antenna. Other side involves the same antenna attached to an unused coat stand and an IPCOP firewall / gateway. A full test has yet to be run but a preliminary test simulating the distance gave 650kb sec throughput (FTP transfer) Can anyone calculate the Mbit from that, hopefully getting around 18-20mbit? Hopefully I will have the link running formally by the end of the week so I can report back the overall throughput at the distance etc etc. I intend to photograph it all and upload it to my website to hopefully help others in a similar situation. BTW, im running the link in bridge mode with everything off that can be turned of (IE, not required), I am not using wep as I have locked Mac addresses and the bridge only allows the other side to communicate.
