FWA710 No download speed.

GrahamP · July 29

Good Morning, I seem to have an issue with a FWA710 router I have installed, along with some AP's and a switch.

The Router is getting a perfect 4G/5G signal, but when i do speed test through its GUI I get 0.01 download and up to 74.1 upload.

When this was first installed, and found this fault I chatted with Tobi AI, and I have done everything he has suggested, It has the latest 1.70 firmware, it is on a pole on the chimney breast of the house, So no wall interference of any kind as it is outside. I am using the original power supply, supplied with the router. I have tried manual APN settings, I have tried manual cellular band settings, (which has increased the upload speed) but still get no download speed.

I feel like I have exhausted all fault finding exercises and still no joy.

I am starting to think that the router might be faulty.

Any help would be greatly appreciated.

Hi there,

To troubleshoot this issue, we recommend the following steps:

Check the SIM data plan — Please confirm with your carrier whether download data is included and active on your SIM plan.
Test with a known-working SIM — Insert a SIM card that you know provides good download/upload speeds into the FWA710. This will help confirm whether the issue follows the original SIM or the router itself.
Test via a directly connected client — Connect a laptop directly to the LAN port of the PoE injector using an Ethernet cable (bypassing your switch and access points), then run a speed test using Speedtest.net or nPerf.

If the download speed is still 0 after completing all the steps above, please share your Nebula Organization and Site name, and enable Zyxel Support access so we can investigate further on our end.

Hi Judith,

I have done all of the above options you have offered, The sim is known working sim and the data plan is working, as the sim has been tested in other devices.

All tests on the router have been done with a hard wired laptop on site.

I will go and allow Nebula Support access and let you have a look.

Hi @GrahamP ,

Thank you for the information. We were able to access your Nebula site and can confirm the download speed shows as 0.01 Mbps, as you reported. We'll investigate the symptom.

By the way, could you please share the download and upload speeds specified in your SIM plan?

Its an umlimited data plan with uncapped speeds.

Hi, sorry to hijack the thread, but I'm experiencing exactly the same issue.

Zyxel modem speedtest showing 0.1 download irrespective of connection speed.

Run speedtest on a device behind the modem (and router) and the download speed relates closer to the connection.

First experience of this was 13/06
