FWA510 -5GNR Problems with Telekom Germany

Jens_S

Hi,

we bought an FW510 and are having problems with the 5G modem in the Telekom network.
An LTE connection can be established, but 5G bands are not used.
As soon as the N78 band is activated, there is even no connection at all.

Tested multiple SIM cards. Everything works with a different brand of router.

Like the issue here:

Is there a similar solution for FW510 with modem module update?
Greetings
Jens

Hi @Jens_S ,

We are pleased to inform you that the issue regarding the absence of a 5G connection with the Telekom SIM card on the N78 band has been successfully resolved by updating to the latest firmware version, 1.17(ACGD.1)C0.
With this resolution in place, we will now be closing this case. We appreciate your cooperation and patience throughout this process.

HI @Jens_S ,

To check whether your FWA510 can get 5G connection, I would suggest the following:

1. 5G signal availability: Check local (Telekom) 5G signal via nperf website, please choose correct Country and Carrier (Operator) https://www.nperf.com/en/map/US/-/-/signal/
2. Firmware Update: Ensure that your FW510 device is running 1.15(ACGD.3)C0 - the latest firmware.
3. Network Settings: Check your Cellular band settings, whether “Band Auto Selection” is enable to allow the router find any possible bands. The path: Network setting > Broadband > Cellular Band.

By the way, could you share with us when you configure the Access Technology as NR5G-SA/NR5G-NSA/4G (Auto Switch), whether System Info and Cellular Info show like below:

Hi Judy,

1. 5G is available
2. Firmware is up to date
3. No connection with 5G. only with LTE.

The same SIM card has 5G with a bandwidth of 900MBit in a Huawei router.

Hi Paul,

hast du schon Neuigkeiten aus deinem Ticket?

Seit gestern versucht Zyxel bei mir via Teramviewer meinen Router anzuschauen.

Bist du auch bei der Telekom?

Hi @Bacanu ,

Hi there,

Your Preferred Access Technology is set as "NR5G-SA/NR5G-NSA/4G (Auto Switch)". The local GUI indicates that the FWA510 operates effectively with both NR5G-NSA and LTE 4G.

System info shows:

Cellular info shows:

If you have any queries regarding NR5G-SA, recommend you reach out to the WINDTRE operator first to ascertain whether Wind Tre or your service package includes NR5G-SA service.
