Nebula FWA505 and a series of issues - connection and Smart Life App

Jii

Hi

They were, I cross-checked what FWA505 reported with what was given for the operator in cellmapper.net. In my case bands were B3 and n78.

@Zyxel_Melen,

I've experienced some improvement in stability with the latest configuration, but there are still occasional connection drops.

Could this be related to the 5G network reception? I'm wondering if external antennas might help improve the connection. If so, do you have any recommendations for compatible antennas for the FWA505?

Thanks again for your support,
Douro

Hi @Jii,

Thanks for the information. Please help to clarify:

1. Is the 5G signal strength good? You can check the dashboard for this information. If it is not good, please place your FWA505 in a place with a better signal.
2. What "Referred Access Technology" are you using? (Path: Network Settings > Broadband > Cellular Band) If it is "NR5G-SA/NR5G-NSA/4G(Auto Switch)", could you change to "NR5G-NSA/4G(Auto Switch)"?

Hi @Douro,

Thanks for your update. I would like to check your 5GHz signal strength first. Please help to access the dashboard to check the signal status. If it is not good, please place your FWA505 in a place with a better signal.

In addition, you may also try changing the "Referred Access Technology" from "NR5G-SA/NR5G-NSA/4G(Auto Switch)" to "NR5G-NSA/4G(Auto Switch)".

Hope it helps.

I have following with external antenna:

Access Technology NR5G-NSA

Signal Strength -99

And the switch was already set to NR5G-NSA/4G(Auto Switch)

Hi, exactly the same problem here with the FWA505 on latest firmware. After max. 1-2 days the 4g/5g connection drops completely (but the leds on the router and inside the gui show that the connection should be perfect - but actually it isn’t). Only hard reboot helps. Tried everything (fixing DNS, fixed bands, and several other settings) —> this is so frustrating! Please fix it in the firmware and as a first step please put a scheduled “reboot” option in the firmware … this should be the least. Thanks, Dirk

Hi @Jii,

Thanks for the update. Can the issue be solved by rebooting your device? If yes, please try to set a scheduled reboot for the workaround.

Since FWA505 is a Nebula support model, please navigate to the Nebula control center to set the schedule. The path is Menu > Site-Wide > Device > Mobile Router > Configuration > Maintenance.

Using scheduled restart does not help, as situation has gone from bad to worse in my case; now in the worst case connection stays up only 2 hours and presently I have to restart FWA505 3-4 times per day. And this after I managed to improve signal strength to -90 by switching back to internal antenna (external antennas have apparently too long cables for 5G's higher frequency).

Hi @Jii,

Could you help me to enable Zyxel support so I can check the "SINR", "RSRP", and "RSRQ".

Please go to Help (identified by a question mark icon at the upper right corner of Nebula portal) > Support Request > Zyxel support Access to enable and save.
