Hello!

My brand new NR5101 from Amazon doesnt want to upgrade firmware. I have V1.00(ACCG.3)C0 firmware installed from the box. I've set it up and the Nebula WEB interface suggest upgrading firmware, but the router doesnt upgrade nor through the WEB GUI, nor through Nebula interface.

Through Nebula interface it says "upgrading" when I select "upgrade now" but after a couple of minutes it returns to the same suggestion of upgrade and the firmware version stays the same.

I've tried also through WEB GUI (192.168.1.1.): downloaded V1.15(ACCG.3)C0 from the Zyxel web site, but it says "wrong image file" when I click "upload". I've also tried resetint the device to factory settings twice - still doesn't upgrade. Tried to upgrade firmware without SIM afte reset - same problem.

    Please going to Nebula > Help (On the top of right) > Support Request > Zyxel support Access to enable and save for us to check. By the way, could we implement the firmware upgrading process to clarify the issue?

    Hi @User4321 ,

    Thank you for your cooperation. We were able to reproduce your issue in the Nebula. We'll analyze the case and provide you with updates.

    Regarding upgrading the firmware via the local GUI, please ensure that you upload the .bin file, not the .zip file. We believe that the message "wrong image file" will appear when you attempt to upload the .zip file.

    Hi Judy

    Thank you for a quick reply and your help. I own a Zyxel LTE3301-plus without Nebula for four years now, so I'm familiar with the Zyxel firmware update process. I've downloaded the firmware update for NR5101 from https://www.zyxel.com/global/en/support/download?model=nebula-nr5101 and I've used the 115ACCG3C0.bin file from zip folder. I've checked everything again and unfortunately update through local GUI is still failing.

    So, I'm looking forward to your analysis results and updates.

    Hi Judy

    Could you please tell me – any updates on my issue?

    I’ve bought this NR5101 for 390 EUR from official Zyxel store, and frankly speaking currently it performs very poorly.

    Same place, same LTE coverage, where my Zyxel LTE 3301-plus shows downlink speeds up to 100 - 120 MBit/sec during the day, NR5101 shows only 50-60 MBit/sec. Uplink speeds dropped from 39 Mbit to 5-11 Mbit/sec. I was hoping that higher LTE category of NR5102 (CAT20) will improve the DL and UL speed significantly, comparing to LTE3301-plus, which is only CAT6, but it doesn’t happen.

    I hope this situation will improve with updated firmware, so I’m looking forward to your reply.
