How to Recover the Access-Point DAP-3690
Before beginning we must keep in mind that the DAP-3690 is an outside AP, so you do not have a button to perform the reset. The only method by which you can restore factory settings is using the console port connected to a PC
Step 1 - Connect one end of the supplied console cable to the console port
of the DAP-3690 and the other to an available serial port on the PC (that you will use to connect to the AP)
Step 2 - Run HyperTerminal on the PC. (If you do not have HyperTerminal installed you can download it from Microsoft or use another program such as Putty.)
• Go to the Start menu
• Select All the programs
• Select Accessories
• Select Communications
• Select HyperTerminal
