In similar scenarios I have seen engineers put together some "bank shot" solutions to bridge networks, like when they put a wireless backbone down the staircase at the Roosevelt Hotel at HOPE 5... <a href="http://www.the-fifth-hope.org/5hwiki/WiFi">http://www.the-fifth-hope.org/5hwiki/WiFi</a> . There are certainly (expensive) dual-radio combos that are of a sufficiently low enough frequency that the occasional brick wall should prove to be less of a problem either figuratively or literally. <a href="http://www.ubnt.com/">http://www.ubnt.com/</a> makes incredibly powerful radios... 900 Mhz at 1W can overcome some difficult masonry issues... are you using bridge-utils or is there a more recent package for wireless bridging?</div><div><br></div><div>"It shoots through schools" - Danny Vermin (in Johnny Dangerously)</div><br><div><div>On Aug 20, 2012, at 9:03 PM, Phil C. wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>Kurt,<br><br>Thank you.
