fr0stbound posted this but i can't find the main post
first,check if you can access your canopy homepage. look here
http://www.testmy.net/t-186161. when you've accessed your homepage, click Tools, then AP evaluation.
2. look at the bottom of the page and click Rescan AP
3. look for a good AP. one that has a low jitter (preferably 1 to 4) and a high RSSI (preferably 500+). when you have done that, take note of its color code.
4. now click Configuration, then click Radio. Enter the color code of your selected AP where it says "Color Code"
5. click "Save Changes" then click "Reboot".
