Zte mf286d will not connect to 4g+

I just realized my 4g router provides way less network speed then my phone. Tried both sim cards (phone&mobile broadband) in my phone, ~80mbit/s. Both sim cards in my router, ~37mbit/s. I now believe that the issue is that ly phone connects with the 4g+ (or lte-advanced) protocoll but the router only uses the regular 4g. This conclusion i base on the fact of the lower speeds and also that my phone shows a 4g+ connectivity icon whereas the router only says 4g (see pic for reference on a router that actually gets 4g+).

The router is supposed to have a cat12 4g chip. I get similar signal strength on my phone and my router (-70dBm). Both use the same band B20 800mhz. My firmware version is Nordic_MF286D_B12.

So my question is simply - why doesn't my router connect to 4g+ and what can I do to fix this? I am considering external antennas but since the signal isn't weaker than the phones I am not sure that would solve the problem.

Your phone is likely much higher "cat" than the router, I think this is the explanation.

What bands does your phone connect to when doing a speed test? You can see this with apps like Network Signal Guru or Netmonster.

You need to check if those bands are supported by your router.

In addition to what @Lucian said, you also need to check if the router can aggregate the bands available at your location, e.g. it supports the necessary combos.

You should be able to see your serving Cell id in MF286D web GUI. With this information you can try to find the mast (or tower) details on cellmapper.net

What's the modem firmware version, as CA download and upload was not fully enabled until the later versions.
