7920 associates to root bridge but not to non-root bridge
I have 7920s using open authentication with WEP128 cipher. I have two 1300 root AP's (with client support) and three non-root AP's (also client support) in the same lab area. The root AP's and non-Root AP's associate and link to each other no problem. However, the 7920's will only associate with the Root APs. If I power down the root APs, the 7920s show "no AP found". I've verified SSID and WEP128 keys. I've also noted that the root AP does have a channel specified under dot11radio0 but the non-roots do not. Do the 7920's just scan for any channel until it finds an association or do I need to specify a channel in the non-root bridges?
