Hi, I have a thinkpad T40 running OpenBSD and live in a small, nice city close to Barcelona whose city hall offers free wifi Internet to everybody.
Unfortunately they do not have a good coverage and where my building is, I don't get any signal. The card is identified by OpenBSD as ath0. I was thinking, as somebody in the thinkpad forum suggested, of "an USB WLAN "dongle", but one of those with an external antenna that is connected through a standard (typically: Reverse) SMA-connector. Next, get a sufficiently long, low-loss cable and a parabolic antenna (some 24 dBi gain, e.g.), mount the antenna at a point having preferably line-of-sight to the WLAN source (the public router/access point), and disable the Atheros internal miniPCI interface (or, is this perhaps even not necessary?). If your Linux will support the particular USB WLAN dongle, then you're in business... otherwise, well, you're in trouble! A few images showing what type of USB WLAN "dongles" I am having in mind are something like this no. 1 http://cgi.ebay.com/USB-11g-Wireless-2-4G-WiFi-WI-FI-LAN-External-Antenna_W0QQitemZ150208258653 or this no. 2 http://cgi.ebay.com/Alfa-50mW-USB-WiFi-24dBi-Grid-w-Mount-WLAN-10-ext_W0QQitemZ130190878170 or this no. 3. http://cgi.ebay.com/802-11g-Wireless-LAN-WLAN-High-Gain-USB-Adapter-Antenna_W0QQitemZ180168479250 An example of an outdoor, high-gain parabolic WLAN antenna is shown here - http://www.embeddedworks.net/antenna/f2400_Outdoor-Parabolic-Grid-Dish.html there are TONS of such available, and at a variety of prices; Google around a bit, and you will find much cheaper ones. " Now, my question is... will this work with OpenBSD? Has any of you tried this? I have googled for a while and found nothing... thanks Pau
