View Full Version : Preferred AP list in WiFi?

Is there a way to select a preferred AP list from within the SB?

I now have a strange problem with one of my two wireless SB2s: About once or twice a day, my SB2 in the office attaches to the WiFi access point in the living room (60 feet away) instead of the AP in the Office (10 feet away). When this occurs, the signal strength drops to <50% and Shoutcast stutters and stops playing. Normally, the office AP has >90% signal. Why would the SB opt for a weaker signal? Does it autoroam? Can I change the order somewhere? Both APs have the same SSID to allow roaming with my laptop.

My only workaround is to change the SSID of the living room AP to something different and reboot the SB.

Office router-AP: Netgear WGR614v5 WPA-PSK Channel 1
Living room AP: Netgear WG602v2 WPA-PSK Channel 11
both SSID's set to broadcast

How does it connect to the second access point without the WPA key? If you never supply it, is it possible it'll never connect? Change your key on the wireless router you don't want it to connect to.

While the OP didn't mention it, there are huge numbers of WiFi access
points without any encryption.

And many still have the factory SSID, typically Linksys

check out kismet and be amazed

But what he did mention, was that his two are encrypted. So this may very well be the trick.

Depending on the AP, it may well be possible to restrict access to it to certain MAC addresses. That could be inconvenient, for instance if a friend brought over a laptop and wanted to connect. But you can use this method to prevent the SB from connecting to this AP.

@FredFredrickson: Both APs have the same SSID and Key (same PSK) in order to allow seamless roaming on the laptop.

@danco: I hadn't thought of mac blocking, I'll check into that on the livingroom AP. Great suggestion!
