Factory Reset Motorola AP-5131

Motorola_AP_5131The Motorola AP-5131 is a fully featured 802.11a/b/g wireless network access point that supports MESH networking.

I recently needed to reset one of these access points and thought it would be useful for anyone else looking for information on the subject.

Step 1. Serial up to the AP5131 with 19200-8-N-1

Step 2. Power cycle the AP5131

Step 3. Press the “Escape” key when the AP5131 states “Press escape key to run boot firmware”.

Step 4. From the “boot>” prompt enter “passwd default”.

Step 5. Reset the system by entering “reset system”.

The AP5131 should perform a full reset and end up at the login prompt after it has booted. The default administrator password is “symbol” (case sensitive).

Note: starting with firmware release the AP51x1 password was changed to “motorola”.

Upon logging in for the first time the administrator should be prompted to change the password. The default administrator username is “admin”.

Note: the default IP address of the AP5131 is and the DHCP server is enabled in the factory configuration so you should be able to connect your PC to the LAN port and then open a web browser to access the Admin GUI.

    Just wanted to say THANK YOU SOOOO MUCH!!!! By any chance do you happen to know where I can download one of the earlier firmware versions? Unless you already posted it that is lol.

  • Michael McNamara January 22, 2009, 1:50 pm

    Hi Sean,

    I’m happy you found the information useful. Unfortunately I don’t have any software for the AP5131 and I believe Motorola requires you to have a support contract to access the software. Thanks for leaving a comment!

  • Elliott99 January 23, 2009, 9:34 pm

    Thank you for the information – It’s very useful. I wonder if you can help me though. My 5131 is playing up… The Green and Amber lights are flashing together everyone 2 seconds and it isn’t assigning me an IP address. I left it off for a few hours whilst I thought out my plan of action but it i’m still having no luck. I wonder if you have heard or came across anything like this before?

    The wireless isn’t working.
    The ethernet isn’t assigning me an IP address and I can’t manually assign one. (The green light flashes at the same time of the Green and Amber on top. It sometimes stays green too).

    I don’t have a clue what is wrong with it and I need to get the network up and running again!!

    I will check back soon! I hope you have an idea!

    Thanks in advance.

    Hi Elliott,

    I don’t have much experience with the AP5131 but let me ask some questions that might get you on track.

    I’m assuming you can access the web management interface, if you can’t access the web management interface how did you configure it (did you configure it?). Let’s assume you did… are you using the DHCP server on the AP5131 or the DHCP server from your broadband router or corporate network? I would suggest you start like this, setup an ESSID and leave the security (WPA/WEP) turned off for now. The AP5131 is designed to be an all in one solution (router/firewall/DHCP server) which can be annoying for us old school folks that just want an 802.11 a/b/g wireless bridge. Do you see the ESSID in the list of available wireless network on your Windows XP laptop/desktop? Accessing the management interface do you see your wireless device associating with the Access Point?

    If you see yourself associated then you know it’s not a wireless problem but rather a DHCP and/or configuration issue.

    I’ve uploaded the Motorola AP5131 Reference Guide to my website. Hopefully it will be of some help.

    Good Luck!

  • Elliott99 January 24, 2009, 9:10 pm

    Hi Michael,

    That’s the problem, I can’t even access the web UI. If I could access the webui then I should hopefully be OK but alas I can’t :(


  • Michael McNamara January 26, 2009, 12:48 am

    Hi Elliot,

    So where you able to connect up to the serial console of the device? I had assumed that you had previously configured the device. You should be able to configure the device from the serial interface as well although you’ll probably need to refer to the reference manual.

    Good Luck!

    hola buena tu informacion ,pero a mi no me sirvio ,te explico tengo un ap-5131 ,lo compre usado y tiene clave ,me conecto pero me pide clave mi pregunta es como entro en el o como lo reseteo si no tiene boton de reseteo si tiene alguna informacion o alguna guia de como desbloquearlo atte arjor gracias.

    • Michael McNamara April 29, 2009, 12:02 am

      Hi Arjor,

      While I took many years of Spanish in High School and College I could only make out a few words above so I through your post into Google (I suspect you’ll need to-do the same in order to read my reply).

      “hey your good information, but I do not sirvio, we have explained an ap-5131, and is used to buy key, I connect but I asked my key question is how come in or as if it has no reset button reset If you have any information or guidance on how to unlock some atte arjor thanks.”

      We’ll even with the translation I can’t say that I really understand your question. Sorry I can’t help.

    • Siquem September 26, 2012, 2:23 am

      La receta funciona como detalles el usuario es admin y el password es symbol o motorola, de acuerdo a la fecha de fabricación, despues del reseteo deberas usar algo para escanear cual es la ip ya que solo está reseteado el password pero sigue conservando la configuración original.

  • arjor May 4, 2009, 11:36 pm

    Hello my name is Jorge, good the publication of the Access point AP-5131, I wanted to know like resetear or desconfigurar the Access point AP-5131 would be thanked for it since it does not have reseteo button, if there some program, aside from the method that you say thank you very much.

    • Michael McNamara May 7, 2009, 2:38 pm

      Hi Arjor,

      I’m not aware of any other method to factory reset the AP-5131 other than cabling up to the device and following the previously posted instructions.

      Good Luck!

  • Eliseo August 20, 2009, 11:51 am

    i can´t acces to my Ap 5131, i need some software or something? becose the cd don’t have anything.
    i nedd a quick answer please, thank you, Eliseo from Argentina

    • Michael McNamara August 20, 2009, 6:52 pm

      Hi Eliseo,

      So when you connect a serial cable up to the AP5131 and configure your terminal application for 19200-8-N-1 you don’t get any output?

      I can’t remember right now but I believe the AP5131 requires a cross-over (DCE/DTE) serial cable. You could use a null modem, if you have one, to check and see whether the AP5131 requires a DTE or DCE connection on the serial port. In any case as you power it on you should definitely see something on the serial port.

      Good Luck!

  • Anish Abdulkhaadar October 3, 2009, 6:10 am

    hi dears ..am new in this ..you all are discussing about the password reset of AP5131..i need to reset the AP to factory default by all means.can any one divert me to the right path?

    • Michael McNamara October 3, 2009, 12:04 pm

      Hi Anish,

      After you login to the CLI interface enter configuration mode, from there you can issue the “default” command.

      Are you sure you want to default the configuration? :

      Good Luck!

  • chander sharma December 15, 2009, 12:28 am

    i am using two access point AP5131Access point

    client bridge
    mesh client bridge setting and select the mesh network after then access point give the reply but not connect with the laptop or mobile device
    please suggest me what i do

    Chander Sharma

  • Jeremy March 17, 2010, 11:12 pm

    My problem is that the default user and password (admin & motorola) do not work!!!! Has anyone else ever encountered this? I personally took this out of the box and there was no indication that it was ever powered on by anyone else who could have changed this. I can bring up the login gui and have tried every combination of admin/administrator and symbol or motorola there is. I have never had to use a serial cable to configure a router before and do not even have on at the moment. Will I be able to reset the password to whatever I please or the “default” that may or may not be motorola? Thanks.


    • Michael McNamara March 17, 2010, 11:28 pm

      Hi Jeremy,

      What version of software is the AP5131 running?

      Unfortunately Motorola (formerly Symbol) has changed the password more than a few times depending on the version of software. You should be careful in that the username and password are case sensitive. You should try the following;


      Were you able to successfully factory default the access point?

      Good Luck!

  • Sergio April 27, 2010, 5:40 pm

    I wonder if you have any manual for “USERS” to reset the AP AP5131, picture or anything else to make this process easier.

    Sergio Rojas

    • Michael McNamara April 28, 2010, 12:16 am

      Hi Sergio,

      You can probably find the procedure buried in some Motorola manual but I don’t believe you’ll find any ‘pictures’. The process above is pretty simple if you familiar with consoling up to various equipment.

      Good Luck!

  • chester king April 27, 2010, 8:34 pm

    I can get in the web ui so I configured it and can ping all clients and server on my network but no internet access. Please help. Thanks in advanced.

  • chester king April 27, 2010, 8:37 pm

    I get no internet access on the wifi clients but can ping any client on my local area network. What’s the wrong? DNS is working correctly.

    • Michael McNamara April 28, 2010, 12:25 am

      Hi Chester,

      Your post really isn’t on-topic regarding the original content of the post.

      You can post questions over on the discussion forums, however I will try to address your question.

      Are you relying on the AP5131 to act as both the wireless access point and the router? You appear to be use two RFC1918 address blocks ( and Is the AP5131 configured to NAT to the public address or are you just routing the IP traffic through the AP5131? If you are routing you’ll need to put a route in your backbone network back to the AP5131.

      You can find the AP5131 reference guide right here.

      Good Luck!

  • chester king April 28, 2010, 7:26 pm

    These are my NAT config:
    WAN IP Address: NAT
    Type:1 to many
    Outbound Mappings: LAN1 IP addresses get translated to
    Inbound mappings: not cofigured.
    Is my NAT config creating this issue?
    Thanks for your reponse.

    Hi, Ive recently aquired a pre configured ap-5131.

    the problem is, I have no idea what the passwords are for it. when I console in, none of the above passwords work.

    Is there a way to master reset this unit, even if it means cracking it open to do so? (Im not shy about this, ive jtagged my linksys wrt54g to unbrick it numerous times)

    • Michael McNamara January 7, 2011, 12:36 am

      Hi Eric,

      Have you performed a factory reset? What version of software is it running?

      Good Luck!

      • Eric Furtado January 17, 2011, 11:58 pm

        nevermind I got it working, thank you so much. Motorola conveniently left this part out of the manuals its seems.

  • Jeremy January 7, 2011, 9:17 am

    Once I performed the factory reset following the above instructions my password was indeed “motorola” Now sure why the password was none of the above right out of the box but hey as long as I got it working I guess. Good Luck!

  • Greg C February 8, 2011, 4:43 pm

    I have two of these devices that are several years old and the firmware is way out of date. I’d like to put them back online but I’m afraid of vulnerabilities so I’d like to update the firmware. Sadly it looks like Motorola/Symbol charges you for a service contract to access new firmware even if it’s for bug fixes and security patches.

    I don’t imagine anyone knows where I can download a more current firmware? I’m on

    • Michael McNamara February 8, 2011, 5:23 pm

      Hi Greg,

      The AP5131 is only a few years old… unfortunately you won’t find any software here. I don’t believe there are any significant security vulnerabilities that would preclude you from using it for home use so long as you use WPA2/AES.

      Good Luck!

  • Eli R February 9, 2011, 9:11 am

    I have 2 motorola AP-5131’s, 1 is working and the other I am unable to connect to. I started reading your tutorial on how to reset the unit back to default but I am stuck at step 1 – serial up… I have a serial cable plugged in and was going to use hyperterminal. The only problem is I don’t know the address to connect to it. I am unable to login to the web interface. The IP’s are all messed up. Any help is greatly appreciated.


    • Michael McNamara February 9, 2011, 5:22 pm

      Hi Eli,

      As I posted above you need to use the serial interface to connect to the AP 5131 and factory reset it. If you’re unsure that your cable or serial port settings are correct try connecting to the working AP5131 and you should get a login prompt. If you don’t get a login prompt then you have the wrong cable (I believe you need a NULL serial cable for Motorola equipment) or you have the wrong baud rate on the port.

      Good Luck!

  • Esteban May 3, 2011, 2:11 pm

    Hi Michael, I have the AP-5131,the null modem cable, the problem is that I forgot the user and password, and I need use my AP with other parameters, I tried to reset the AP-5131 password with your instructions but when I press the “ESC” key the boot continues normally and the prompt no display for type “passwd default” What I can do?


    • Michael McNamara May 3, 2011, 9:37 pm

      Hi Esteban,

      Perhaps it’s the terminal emulation that you are using? You might want to try a different emulation type such as VT100. I’m assuming that you can type in a username when the AP5131 boots so that proves that your serial cable is good.

      Good Luck!

  • Steve November 4, 2011, 10:42 am

    Hi Michael, I have the AP-5131,I’ve used a null modem cable to reset everything so to speak. I’ve set the admin password and country code. I’ve also set the VLAN mask to and my pc to, mask however I’m still unable to connect to the AP thur the IE. I only get as far as the AP-5131 Access Point Login screen. When I enter my admin ID and password all I get nothing not even an invalid password message. Of course if I enter an invalid password it does tell me I did that. Please help! Steve

    • Michael McNamara November 6, 2011, 12:07 am

      Hi Steve,

      What are you using for the username and password?


  • Steve November 7, 2011, 10:17 am

    The firmware version is 2. something so I used admin and motorola as the PW then changed it via serial connection. I’ve tried it with another computer since my last posting and was able to connect with that system. Still don’t know what is stopping me with this one. I’m on IE 7 with the latest java verison. same as the other pc.

  • Leonidas January 22, 2012, 8:16 am

    I cannot get connected to a Motorola AP-5131 neither via utp (cannot ping or nor with a serial cable (via hyperterminal)!! What should i do?
    Can i use a simple 9F-9F serial cable to hyperterminal Motorola AP-5131 or do i have to use only Motorola’s 25-96992-01R serial cable??

      Hi Leonidas,

      I would start by validating that your serial cable and HyperTerminal settings are correct and fucntional. Do you have another AP-5131 or similar AP that you could use to test your serial cable and terminal settings? I believe the AP-5131, AP-7131 and RFS4000, RFS6000, RFS7000 all utilize an RJ-45 console port cable (rollover) similar to Cisco. However, they utilize 19200 bps as opposed to the usual default of 9600 bps for most manufacturers.

      Good Luck!

      Hi Kamal,

      You’ll need to connect to the serial/console port of the AP-5131. I would start by verifying that the serial port on your laptop/desktop works – can you connect to anything else. Are you sure you have the correct serial cable? I believe it should be the same as a Cisco console cable. When you have that working you’ll know that isn’t your issue – then just connect to the AP-5131 with 19200-8-N-1 and you should be set to go.

      Good Luck!

      Your syntax looks all wrong to me… you probably need to refer to the manual.

      Good Luck!

    what program should I use in Windows 7 to connect to the console port in the AP5131.

    • Michael McNamara May 23, 2013, 4:42 pm

      You can use any terminal emulator such as HyperTerminal or PuTTY.

    Hi Michael,

    Firstly thanks questions and answers to get me this far.

    I am trying to configure a (Motorola brand) AP5131 to a (DHCP) cable modem. Modem cable into POE “data in” and data out to LAN on the AP. No problems with configuring the SSID and securing WPA2. I can connect with my notebook but no internet access.

    Have I missed something? Gateway?
    Do I need new firmware to support the new IP4 / IP6?

    Really looking forward to your reply. Thanks

      Hi James,

      Your just utilizing the AP as a simple wireless bridge… you should get your DHCP address, etc from the cable modem. Are you able to ping the cable modem (default gateway)?

      Good Luck!

      Hi Gerard,

      I believe the configuration should be retained to whatever the ‘admin’ password was previously should still be configured. You can try the standard defaults;


      If that doesn’t work you’ll need to factory reset the AP per the instructions above.

      Good Luck!
