    Using ENH202 to service a back lot and several small produce storage areas with sliding doors that allow signal to radiate into the coolers.  System was working 100% until recently when we lost the AP's Wi-Fi signal.

    Removed the AP to our bench and connected to our 192.168.1.xxx network for testing. 

    Using our shop POE injector we do have Wi-Fi signal again so we may have a PS issue at the site.  Strangely enough we could still access the router GUI via the LAN connection when the Wi-Fi was missing!?

    Device IP is 192.168.2.xxx BUT we are seeing that it is using our in-house DHCP server to issue addresses on the Wi-Fi in the range of 192.168.1.xxx.

    Trying to understand how the device is able to communicate with our server across the 192.168.1.xxx LAN with the current 192.168.2.xxx IP address.

    Seems the AP should not know anything about our local DHCP server.

    Tech says the device is a bridge but we are running AP mode and on a completely different network.

    Anyone able to elaborate?


    The ENH202 when configure as Access Point, it must be connected to a Router or DHCP server. The access point will only advertise IP address coming from the  DHCP server or Router since it has no DHCP service.

    Best Regards

    Ok after taking a break from this I have done some more investigation and believe we are on to something here!

    On my machine, I usually run a DHCP server in addition to the static IPs.  So I'll have, for example, and as my static IPs.  I'll also have a DHCP server dishing out IPs in the range.

    So I break out another fresh radio (this time ENS500EXT-AC) and this one, out of the box, I can't ping it at  I run traceroute on it anyway though:

    traceroute to (, 30 hops max, 60 byte packets
     1 (  0.735 ms  0.565 ms  0.617 ms
     2  * * *
     3  * * *
     4  * * *

     7  * * *
     8  * * *
     9  * * *
    10  * * *
    11  * * *

    Ahh here we go!  The device is actually at  It's gotten a DHCP address, but is still responding (kinda?) to  I'm guessing this is a new behavior in firmware version "1.0.0 + 1.8.53".

    I'd suggest in the next firmware to update it to not use DHCP, or to amend the manual @ https://www.engeniustech.com/engenius-products/enturbo-outdoor-5-ghz-11ac-wave-2-wireless-access-point/ to note that it will come up in DHCP by default.


    Thanks for all the effort and finding in regards to the above issue. Yes you are correct, the IP setting of the ENS620EXT will become DHCP after updating to firmware version 1.0.0 c1.8.53.

                Rationale: So the EWS Controller and ezMaster can easily find, add, manage, and control the access point.

    I will forward this to the engineers for confirmation and possible manual revisions.

    I've tried with different INT, ETSI and FCC firmwares, no success. By the way I think the 3.0 FW is not region restricted. There are 3 versions of 2.0.361 FW for example, with headers





    In case of 3.0 there is just



    ALL, not ETSI, INT or FCC.


    Did you try flashing the firmware FWINFO-EAP1750H-FCC-v2.0.361-160519 to your EAP1750H  then try downgrading the firmware.

    As I have faced serious VLAN issues I've decided to downgrade the FW. Unfortunately I'm not able to do that as I'm getting the error


    Firmware upgrade is failed for unexpected reasons. Please make sure your firmware is valid.


    All I can do is to reflash the current FW. Is the FW downgrade forbidden?

    It is possible that the firmware you are trying to upload is not compatible with your hardware. As mentioned above the firmware version 3.0 has not released in the US, you may try contacting EnGenius Europe for compatible firmware for your EAP1750H. See below:

    I have three EnGenius EAP1300EXT access points. Visiting https://www.engeniustech.com/engenius-products/enturbo-11ac-wave-2-indoor-wireless-ap-w-high-gain-antennas/ showed that new firmware was available, so I upgraded one of my access points to make sure everything works ok before upgrading the other two. It appeared that the upgrade completed ok.

    Problem is that after the firmware upgrade completed, I can no longer access the CP. I get the login screen, and using my user default name and password shows an invalid username or password. I tried using the factory default, no joy.

    Even though there's no documentation for this model on the hardware reset button, I tried it several ways, 10 seconds, 30 seconds powered, unpowered, and going from unpowered to powered. No joy there either, only now if I try logging in using my username and the default 'admin' password, I get a white screen. Trying any other combination shows invalid username or password.

    Wifi Explorer shows the unit is online and connecting to clients normally using the SSID & WPA2 passcode as I set it up before the upgrade. It's only the CP that I can't access, so I can't make any future changes.

    Looking at that white page Chrome console shows a 404 error, and looking at the page source looks like the standard login screen.

    Using Device Discovery on the Tools page of another AP on the network sees the AP and it's showing firmware 3.0.0 (the other APs show firmware 1.0.0).

    So at this point I'm not upgrading my other APs to the newer firmware. My network is operating ok (even the AP with newer firmware) and no users are affected by this issue, only the poor admin (me) who can no longer control or make any changes to the AP. 

    Does anyone on this forum have any ideas or suggestions? I did backup the configuration, but there's no way to restore it without access to the CP, otherwise I'd have tried that.

    Thanks in advance for any wizardry out there that can help!


    I see that you are having issues with your EAP1300EXT after updating its firmware to the latest build. Could you please let me know as to where you downloaded the firmware? It may perhaps a cache error on the browser? Have you tried clearing the browser histories, cache page, form data, password, offline sites, etc. then re-launch the browser? Have you tried using a different browser?

    You may also try pressing and holding the reset button for 1 minute while powered on. After a minute, release the reset button then disconnect the power for 10 seconds.

    We're gonna have another one of our team try it tomorrow with a 3rd radio and see if he has any better luck. 

    I've updated firmware so many times on these things though it's just hard for me to fathom that I could be screwing it up somehow.

    laireV do you know if the set of radios you've been updating from was on, or something more recent?

    I see. There is no other firmware release after It has the same firmware as yours.

    Ok so I set aside RADIO1 as a brick and pulled grabbed a new ENS620EXT I had just provisioned.  Firmware version according to the Javascript in the admin interface.

    * Began the firmware upgrade steps with a factory reset.  Held reset button for ~30 seconds.  Removed power.  Waited 30 seconds.  Applied power again.  Device comes up at  Good so far.

    * Uploaded ENS620EXTaddCAPWAP.bin.  SHA256 sum of that file I have is: ac119efb30dd1c05054f79f71f9415d88410cc4f1f9c501e43c9660752f4d375

    * Firmware upgrade timer starts at 600 seconds.  I let it be and come back and can get to the device fine at   The admin page shows its version to be "1.0.0 + 1.8.53".

    * Proceed with second factory reset.  Held reset button for ~30 seconds.  Removed power.  Waited 30 seconds.  Applied power again.  Device does NOT come up at 

    So I've got two bricks now.  Unless I'm doing something really wrong, or we have a box of bad radios, I have to suspect there could be a bug in the firmware upgrade process from to the latest.

    Never had any issues updating the firmware of my ENS620EXT using the same exact procedure posted on the website.

    I have a set of ENS620EXT radios and was attempting to upgrade one to the latest firmware.  Downloaded version from the site, as a RAR file.  Unpacked it and found these instructions:

    1) Factory Rest the ENS620EXT
    2) Upload the ENS620EXTaddCAPWAP.bin file first to the ENS620EXT
    3) Factory Reset the ENS620EXT
    4) Upload the ENS620EXT-int- to the unit
    5) Factory reset unit
    6) The unit should be ready to work with EWS switch or ezMaster Network Managment Software.

    A bit more than I'm used to seeing, but I began following it step by step.  Steps 1 and 2 went fine, but after doing the factory reset in step 3, the device no longer boots and I can't ping it at (except for a few brief seconds when it powers up). 

    Has anyone successfully performed this firmware update?  From looking at the Javascript code on another radio, I believe the exact version of the current firmware I'm on is

    This should be the correct steps on how update the firmware of the ENS620EXT. At step 3. Perform a 30 second hardware reset (exactly 30 seconds). 

  9. Spanning Tree Protocol (STP) is a network protocol that ensures a loop-free topology for any bridged Ethernet local area network. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. Spanning tree also allows a network design to include spare (redundant) links to provide automatic backup paths if an active link fails, without the danger of bridge loops, or the need for manual enabling/disabling of these backup links.

    If you have multiple wireless bridges linked together, you can enable the STP for redundant path/link.

    I see. I honestly do not have any word from the engineering team here in the US. However if there will be v3.0 firmware for EAP1750H (US version), it will be posted on EnGenius US website.

    No worries. This community forum is not only for US. Your post caught my attention so I did respond. Hopefully, EnGenius Europe would also find this interesting.

    There may possibly a change on the MIB file as the configuration settings has also changed on the new firmware code. I will check with the engineering team and if possible getting the latest MIB file from them.


    Just curious, where did you get the firmware v3.0.0 for EAP1750H? 

    EnGenius US do not have this version of firmware. For EAP1750H US version, firmware can only be downloaded from the link below:
