That's what I was thinking: isn't it a problem to have to APs with same SSID (and maybe the same channel) in reach of each other? Don't the clients get confused? Or are the drivers usually smart enough not to flap between the two? Many righteous WLAN cards have the election process

Assuming you want continiois coverage, same channel is actually best, unless you can go cross-band, which impacts roaming. The number of people who don't understand this, and instead want to talk about 3 non-overlapping channels and other cr*p is amazing. Same ESSID is what you want, too.

They most likely are getting it from Cisco of all places. Cisco talks about using 3 non-overlapping channels when establishing a multi-AP roaming wireless network with their APs, and they explain the reasoning behind it in their documentation. Bottom line, if there is too much overlap on the

at the risk of talking about cisco gear on a freebsd list, they're full of it. In 802.11 the client gets to 'pick' the AP it associates to. Scanning (which is a client activity) off channel takes more time than scanning on-channel. Thus, a client could pick an AP 'on-channel' more
