@androll Ok, thanks for the explanation, I understood that this is unfortunately a different error than the one I encountered. I have a changelog of module version changes from A11 to A12. If I had this problem, I would look for a changelog from version A08 to A11 if this error was eliminated and then I would try to update…

@androll You can try to change IPv4 to IPv4v6 and set the option to save router logs. If you want to check the logs, you have to click the button to download the file to your computer, because they are not displayed in the router. There you can check if the router loses its connection forever, or if it can reconnect to the…

@androll Unfortunately not. I don't have the right phone to connect to the router and I won't have one. Taking this opportunity, I would like to add that the router has been working flawlessly for 16 days without turning it off :D

@JeanFrancois In "Celluar APN" I set IPv4v6 and since 11 days I have no problems with disconnecting the Internet. I checked if the IPv4 address changes and yes it does router loses connection and reconnects after a few seconds. It is true that I changed the network from Orange to T-Mobile, but it also disconnected me from…

@Zonha It's great that you managed to find a solution :) I did the update using a cable connection. From what I was able to find, I have an Excel file with the given band aggregation possibilities. I do not know why it is stated that the LTE module supports aggregation of 5 bands, and there are only 4 in this file.…

@Zonha Hello, What version of router firmware are you using? Are you downloading the correct software version for your region (Europe/Australia or USA)? I was updating on version V1.00(ABQV.3)C0. The download link is available below: https://www.zyxel.com/pl/pl/support/download?model=lte5398-m904 I have prepared a video…

@BruCom In general, last week I changed the operator to T-mobile to check if the router will not drop the connection. Internet speed increased from 131 Mbps to 179 Mbps when aggregating the two bands BC_1 and BC_3. I changed the location of the router, which turned it off and on again. On May 28 at 14:30 my Internet…

@fabriba It should be rather "Cellular APN", but I found this option :) You can set IPv4/IPv6 there, but I don't know which option the router is currently using, whether IPv4 or IPv6. It is only shown that it uses IPv4v6. I went into System Info -> WAN Information and found the following information. Does the "N/A" in the…

@JeanFrancois Hey how do I check if my router is currently using IPv4 or IPv6? In which tab is this information located?

@BruCom Thank you for explaining the problem with the inability to upload the A12 version. It's good that the system showed an error and did not damage the router. I read that about updating the LTE module you need to turn off and on the router and reset the router to factory settings. I did not do that. I only turned off…

@tonygibbs16 Yes, I managed to update the LTE module to the A11M4G version. The latest firmware version for the router is V.3: https://www.zyxel.com/pl/pl/support/download?model=lte5398-m904 Changes in this version are available here: https://download.zyxel.com /LTE5398-M904/firmware/LTE5398-M904_V1.00(ABQV.3)C0_2.pdf…

Unfortunately, I do not have an analog phone to connect it to the router and test it. In my opinion, Zyxel produces hardware and software V1.00(ABQV.3)C0. Quectel releases software updates for its LTE-A EG18 modem and updates all its functions. Qectel is the publisher of the update file, not NetGear. It depends on the…

I was looking for information about this module on the forums and found a thread about updating the firmware for this LTE module. Below link: https://community.netgear.com/t5/Orbi-4G-LTE-5G/LBR20-probl%C3%A8me-de-connexion-orange-en-4G-LTE/td-p/1990719 I suggested the firmware version that was given there. @androll I don't…

Because both devices use the same LTE modem model EG18-EA:

Yes, I found update the modem firmware. Description in my post: https://community.zyxel.com/en/discussion/16882/lte5398-m904-lte-module-upgrade#latest
