NR5101 - much Problems

Hello,
I have bought the Zyxel NR5101 because it is the only 5G device at the German market with antenna connectors. But I am not happy with this device. I planned to use it at home with Vodafone 5G network (700 MHz). But the router seems not able to find the 5G network. Also it seems that it is not able to seek for 5G (or 4G) networks. And fully unhappy it is that there is no manual for the router in the download area and not in the delivery box. If I set the network to "NR5G" (What is NR5G ?) the router find nothing. If I set it back to auto he also find nothing - no 4G network, no 5G network. What it is for an alpha version ? I paid 600 Euro for an 5G device that can`t use 5G ? And for what is the int/ext switch at the back of the device ?
It would be nice to get help for that device.

    Hello @Antennenfreak

    Zyxel Support Campus have just posted 4 days ago an initial setup video for the NR5101 at https://www.youtube.com/watch?v=T-VKIXlUves

    The user guide is available from this page https://support.zyxel.eu/hc/en-us/articles/4403365084818-Advanced-Downloads-for-5G-devices if you select NR5101 in the model selector.

    I hope that this is helpful.

    Kind regards,

    Hello @Antennenfreak

    The int/ext switch switches between the Internal and External antennas for cellular reception.

    The connectors for Ant1 and Ant2 are half way down the back of the device, behind a panel I think, see https://www.zyxel.com/uk/en/products_services/5G-NR-Indoor-Router-NR5101/photos and are SMA connectors, see Hardware Specifications at https://www.zyxel.com/uk/en/products_services/5G-NR-Indoor-Router-NR5101/specifications

    If you have external antennas connected to Ant1 or Ant2 or both, then you need to move the switch to Ext position in order to use the external antennas to improve your cellular reception.

  • I have installed the newest firmware and newest modem firmware. Now I have SOMETIMES 5Gbut not every time at the same position where the Huawei CPE 5G Pro2 has 5G every time. The firmware is buggy, in the manual I see the possibility to switch between internal and external antenna but that is not in the firmware. 5G I had only after I canceled Band20 at LTE. The switch at the Router between internal and external antenna seems to be no function. The RSRP is the same, also when I have no antenna at the router. When I switch to NR5G only I have no network, 5G I gave only in automatic mode. 
    It seems to be an alpha version of a device. It is definitely not the best device of Zyxel.

    Hi @Antennenfreak

    NR5G mode is for the 5G SA mode. 
    I suppose that Vodafone's 5G network is in NSA mode, so you have to use automatic mode.

    Hi,

    It’s not my meaning to ”hi-jack” from thread starter, only sharing similar experiences with my NR5101.

    I’m using it for travel, most of the time located in Denmark, using the Danish provider TDC, which have great 5G covering and the NR5101 is performing very well and satisfying.

    I have been traveling in Austria (Tyrol), using the same TDC SIM in the NR5101 which of course then roaming, however can’t remember provider. The experience was very well, 5G covering and great performance.

    But my experience using it in Germany is quite disappointing. I have been at different locations, and the experience is pretty much the same. Very poor performance, or no connection at all. Right now, I’m located in Niedersachsen, and I can’t get any connection with the NR5101. However, the “Cellular connection status” states that I’m connected, roaming on Telekom.de. But there is absolutely no internet connection.

    Besides the NR5101 I’m bringing a little Huawei 4G “pocket modem” equipped with similar TDC SIM. What surprises me is, that it’s providing decent 4G internet connection, even the NR5101 is not. I notice that the Huawei is roaming on Vodafone.de, which make me wonder, if that would be of any better result for the NR5101 to use. But I have not succeeded to find out, how to force the NR5101 to use Vodafone.de instead of Telekom.de. I have tried from Network setting->Broadband->Cellular PLMN, disabling PLMN Auto Selection, and then trying to chose Vodafone.de from the list. But it seems that it’s somehow not working, it’s not changing.

    Not saying it’s all about the NR5101, I’m not mobile broadband specialist at all, but I’m a bit incomprehensible to, that it’s not at least doing it as well as my 65 EUR Huawei 4G “pocket modem”

    Any suggestion on how to get better result?

    Best regards Ole
