Please log in for more thread options to my wireless router AP. So my questions are, in effect, where do I go from here? a) I've got AT&T wireless service, and am told that when I happen to be within a hotspot location, I should be able to scan for APs and identify the AT&T netork as "attwifi". Is the procedure to head out to a hot spot, scan for this attwifi AP, and then set up a profile for that network? That is, I'd like to be able to connect with wifi from console or terminal. b) Will that one profile serve for all AT&T hotspots across the country? Is there anyway to find out the location of hotspots without actually being there? If I plan to travel to Podunk Hollow, for example, can I know in advance there's a hotspot in Joe's Barber Shop? c) I scanned for hotspots using a gui utility named "wifi-radar". Can I do the same thing from command line? That is, what commands would be used to 1) scan for hotspots, 2) define their profiles, c) connect to one? d) When I boot with a CAT5 cable connected to my router, I find that eth0 is UP and obtains an IP address from it, while the wlan0 interface is DOWN. To connect by wifi, I have to issue the commands # ifconfig eth0 down and # ifconfig wlan0 up. This works, and I prefer a command line, but not sure if this is the proper way to do it. e) How would I reverse priority so that when I boot wlan0 starts in an UP condition, and eth0 is down. Do I simply reverse the order of the stanzas in /etc/network/interfaces ? -- Haines Brown, KB1GRM | ||||||||||||||||

Please log in for more thread options to answer most of my questions, although my answers remain tentative and were picked up by accident as I stubmled about in the dark. Life would have been easier had I known of a handy source for the definitions of key terms and concepts and had found a simple overview. My only remaining question: -- Haines Brown, KB1GRM | ||||||||||||||||

Any centralized list would require the hotspot provider to put themselves on the list. And there could be many non-related lists. Now commercial hotspots likes McDonalds, Starbucks, etc. can be found on their respective home pages. | ||||||||||||||||

You might try a google search for hotspot "Podunk Hollow" Quite effective. A more structured approach might include http://jiwire.com which has a lot of spots, and any spot can list themselves there. -- Clarence A Dold - Hidden Valley Lake, CA, USA GPS: 38.8,-122.5 | ||||||||||||||||
