TRB500 low download speed

Dear community,

I am writing you because I am struggling with the commissioning of my brand new TRB500.
I’ve decided to go for a TRB500 because I live near a mobile tower I do have a good 5G/4G signal. Before installing the TRB500 as intended I’ve done a few performance tests in a good environment to see if the device is working well. Unfortunately, I’ve always achieved less than 240 mbits in download speed - even though I’ve achieved the full download speed with other devices (600 mbits). The upload speed is good though.

Is there anything else I could do?
Is there a firmware or modem related issue?
Are my expectations too high - considering possible differences in the carrier aggregation technology used in the TRB500.

Please share your thoughts with me.

sup, try this: Band Lock - Teltonika Networks Wiki

since you’re getting fair to poor/good values on some signal values that could mess with the speeds.

what devices are u referring to? if a phone for example, the mobile module inside of it has a completely different structure and they’re almost always gonna outperform routers and such

Hello,

Thank you for reaching out and sharing the details regarding your experience with the TRB500.

As you already have an active support ticket created on our internal email platform, you should have received a message from our engineer regarding the speed performance during commissioning. If possible, I kindly encourage you to continue the conversation directly through that ticket so our engineer can thoroughly troubleshoot and analyze the situation with you.

Please don’t hesitate to reach out if you need anything else in the meantime.

Best regards,

Hi,

thanks for your comment!
I forgot to mention that I’ve tried locking the bands earlier.

Fortunately, my e-mail inquiry was received and I got support from Teltonika.
I have followed their advice and got very good results.

Adjusting the PDP typte to IPv4 only and setting the APN selection to manually made a huge difference.

Now I am able to achive the maximum download/upload speeds of my Sim-card (600/60).
I am very happy with the performance of my TRB500.

Hi,

thank you for your reply!
I’ve followed the advice and the performance of my TRB500 is great (600 down/ 60up - which is the SIM-maximum).

We can close this ticket.

nice, awesome Daniel, enjoy the device
