Let me guess: Your mobile phone is on a 2 GHz channel (1-13)? If that is true, then the AP on channel 36 (5 GHz) with good RSSI (83%) will always win because this is how join was taught to make decisions: * Given two APs, determine the "better" one of the two. * We compute a score based on the following attributes: * * crypto: wpa2 > wpa1 > wep > open * band: 5 GHz > 2 GHz provided 5 GHz rssi is above threshold * rssi: rssi1 > rssi2 as a numeric comparison with a slight * disadvantage for 2 GHz APs * * Crypto carries most weight, followed by band, followed by rssi. > Attaching to this particular net would be helpful - saves some time > avoiding workaraounds... You can use 'ifconfig iwm0 nwid phone' to override auto-join decisions and always attach to a network called 'phone'. To re-enable automatic network selection you can use: ifconfig iwm0 -nwid
