Common Problems and Solutions

Symptom/Question

Possible Solution/Answer

I forgot my password and now I 
can’t access the Access Point’s 
configuration tool.

Contact Proxim Technical Support for 
assistance.

I can’t remember the static 
IP address that I assigned to the 
Access Point.

Contact Proxim Technical Support for 
assistance.

I’m using the Access Point in 
Independent mode.  What 
happens if I add an AP Controller 
to the network?

The Access Point will exit from Independent 
mode and partner with the AP Controller 
approximately one minute after the 
AP Controller is connected to the network.  
The AP’s Status LED will turn solid green.

I moved the Access Point to a 
network that has an AP Controller 
installed.  However, the Access 
Point does not partner with the AP 
Controller.

Check the Access Point’s IP address.  If you 
have assigned a static IP address, set 

Use 

DHCP

 back to 

Yes

.  When an AP is connected 

to a network that contains an AP Controller, 
its IP address assignment should come from 
the AP Controller.  This applies even if you 
want to assign a static IP address to the AP; 
in this case, use the Harmony System’s 

Specify IP

 option.  See the 

Harmony AP 

Controller User’s Guide for details.

What happens if my AP Controller 
fails?  Will the Access Point switch 
to Independent mode?

If an AP Controller fails, the Access Point will 
not switch to Independent mode.  The unit’s 
Status LED will turn amber once the Access 
Point has detected that the AP Controller is 
no longer available.  If the AP Controller 
remains down, recycle power to the Access 
Point; the Access Point will operate in 
Independent mode after it reboots.
