APX120 non-functional

Casual_User

My AP30 would have connectivity issues whenever I updated the firmware on my XG.  Other than that, it was rock solid.  It was posted elsewhere that the AP30 is an end-of-life product and no longer supported.  So, I purchased an APX120.  I connected it last night.  It sat with a solid red light for a few minutes before being recognized by the XG.  I did a brief test to ensure that the devices were connected via WiFi.  They were, so I left it.

While I was away during the day, the APX120 continually dropped connections to the point that it was not possible to browse websites.  I could not find any settings to better this.

Tonight I decided to reset it by pressing and holding the reset button.  The manual says to hold the reset button until the LED blinks red.  I tried this but it never got to the blink red state.  It stayed at solid red.  So, I released the reset button.  It then went into a cycle of solid red followed by flashing green and then solid red again.  This lasted for 5 minutes.  Since there was absolutely no progress, I disconnected the power and plugged it back in after a minute.  Now it just sits with a solid red light.  At no point did it flash red which would have indicated it was doing a firmware update.

I've replaced the ethernet cable in case something went wrong when I was unplugging things, no change.

I've tried the reset button again, but nothing.  I've left it unplugged for 10 minutes and no change.

I've rebooted the XG and no change.

It would be really nice if there was some type of feedback on the APX120 or the XG to let me know what is going on or not going on.  Troubleshooting appears to be limited to "the light is red = something is wrong".  

At the moment, I have an expensive red LED light for my office.

    Hi,

    check the logviewer authentication and system views.

    Hi Ian,

    I've checked there.  The Authentication logs only covers my logging into the XG.  The SYSTEM logs show the APX120 under "Wireless Protection" as "Successful sent config to AP" every few minutes throughout the day, but nothing this evening after I power cycled it.

    The APX120 is not listed under my DHCP addresses either.  Seems it just powers on but does not try to connect to anything.

    Hi,

    do you have a switch between the AP and the XG, are you using VLANs?

    Have you tried restarting the XG without the AP connected?

    Odd, the DHCP should at least get a request. 

    Did you check, that there is actually a DHCP Server of XG running for this Port?

     

    Could you perform a tcpdump? 

     

    tcpdump -ni any port 67 or port 68 

    That should be enough, replug the AP, let it boot and check, if some packets are arriving on advanced console.

    Hi Ian,

    Yes, I have a Cisco switch that all my devices are plugged into.  The switch is not KVM, so there are no settings to change on it.  It has been rock solid for the past 6 years running continuously without a single issue.

    I have not tried starting the XG with the APX120 disconnected.  That will have to wait until tomorrow night as the internet here is used heavily during the day.

    My switch is located in the basement.  I have network cables running into wall outlets in the office.  I decided to plug the AP30 directly into the switch using a ethernet cable and a power cable (to bypass the POE injector).  The lights on the switch did not light up which indicated that the AP30 was not making a connection.  This is very odd given it was working perfectly two days ago until I plugged in the APX120.

    I then plugged in the APX120.  The lights on the port go solid green for two seconds, flash then go dark.  It repeats this every 10 seconds or so.  I went to the XG logs to see if there were any connection attempts/logs.  There is nothing in SYSTEM other than the last connection it had yesterday before I power cycled the unit.

    I had created new firewall rules last night to allow any LAN traffic (regardless whether it had a DHCP issued address) to the WAN.  I also created a similar NAT MASQ rule.  This didn't make a difference.

    Yes, my entire LAN runs off one port.  All the other devices on this port are running normally and acquire the proper DHCP addresses.

    I logged into the console and tried your tcpdump command.  The console gives me an error "Unknown parameter 'any'".  If I shorten it down to just "tcpdump -n port 67" it gives me an error "Unknown parameter 'port'".

    It appears that the way this should be entered on the XG is (Port1 is my LAN):
    > tcpdump interface Port1 'port 67'

    and

    > tcpdump interface Port1 'port 68'

    When I run the above commands on the console, nothing is returned as per the below snippet:
