Just got a FWA510 and been trying to use it over the weekend.

After the unit has been turned of for 3-4+ hours it starts dropping the connection, I'm guessing it's loosing connection to the mobile network after looking in the logs.

Once it starts dropping the connection it will keep on doing it randomly several times an hour until i reboot the unit.

It happens both when I have 4G and 5G reception.

The only time the router worked for more than 5-6 hours was yesterday when I placed the router in the middle of the room on the floor, instead of having it in a corner or inbetween the wall&couch

I've tried reseting the router on the button on the bottom of the unit.

Latest firmware is installed.

A colleague bought the same router and haven't experienced this at all, he has placed the router by the window. I can't put the router by I window since I have floor to ceiling windows so it would look pretty bad having the router on the floor by the window.

Does anybody recognize this behaviour and maybe knows how to fix this?

The logs look a bit different every time but around the drops I've seen this :

    Hi @chris238975 ,

    The stability of your mobile router's connection is largely influenced by signal strength. When the router is situated between walls and furniture, such as a couch, obstacles can impede the signal, leading to instability. To enhance this, we recommend the following steps:

    • Utilize the Zyxel Air app to assess signal strength in various areas of your environment. This will help you identify the most optimal location for your router. Additionally, adjusting the orientation of the router can significantly improve signal reception. Ideally, position the router so that it faces a window and the nearest base station for the best results.
    • Examine your surroundings for any environmental factors that could be negatively impacting the signal. This includes electronic devices and large metal objects in close proximity to the router. Relocating these items away from the router may enhance connection stability.

    when the router was placed in between the couch and wall it had 4-6 inches on each side and the front side was open out towards the room. It went between really great 4G and good 5G, and it switched between 4G and 5G no problem.
    In the corner of the room it was close to the walls on two sides of the router and then open out towards the room on the other two sides. Same connection quality here as when I had I placed at the couch.
    I used the app to verify that I had a good connection where I placed the router

    So, it’s not like I have them in a closed cabinet or anything.
    I understand that connection quality is affected when the router is placed in closed spaces , but the drop outs that I’m experiencing are at least 3-5 minutes. That can’t be the right way of handling connection issues, I have huawei , TP-link and a asus mobile 4G routers on different locations and none of them behaves like this.

    Are 3-5 minute drop outs the FWA510 way of handling mobile connection loss?
    Why do the drop outs occur more frequently after the first one happens ?
    And why do the drop outs stop when I reboot the router ?
    There has to be something wrong with my unit

    Hi there,

    Thank you for providing a detailed description. If you're experiencing connection drops, typically 3-5 minutes, despite having great 4G and 5G signals, we would like to assist you further with an in-depth analysis. Here's how you can enable us to do so:

    • Enable Zyxel support by navigating to 'Help' (identified by a question mark icon at the top right corner of Nebula portal) > 'Support Request' > 'Zyxel Support Access', then click 'Enable' and 'Save'.
    • Provide us with the name of your Nebula organization/site here or via the private message by clinking to my account > Message.
    • If possible, please arrange a Teamviewer remote session and we can confirm the suitable time to implement that. This will allow us to gather the FWA510 log during a connection drop event.

    Your cooperation is greatly appreciated.
