I called a antenna web site that was linked from the Seattle Wireless site. They had a 5dbi antenna for appx $69.00 while FAB-Corp has one for appx $35.00. They could not explain why their's might be better. They also pointed out, however, that increasing the gain on the AP may not be sufficient if the laptop's wirless card is insufficiently powered too. They implied that the AP's antenna might be able to "see" the laptop but the laptop may be unable to "see" the AP. Is he just trying to sell me more hardware or is his point valid? I would think increasing the range of the AP should produce a coverage donut that more strongly encompasses the laptop even if the laptop's card remains the same, no? -- Jake Colman Principia Partners LLC Phone: (201) 209-2467 Harborside Financial Center Fax: (201) 946-0320 902 Plaza Two E-mail: [EMAIL PROTECTED] Jersey City, NJ 07311 www.principiapartners.com -- NYCwireless - http://www.nycwireless.net/ Un/Subscribe: http://lists.nycwireless.net/mailman/listinfo/nycwireless/ Archives: http://lists.nycwireless.net/pipermail/nycwireless/
