Looking for new LTE/5G router

Hello. I am looking for a new LTE/5G router. I have a ZTE MF289D but flashing it with OpenWrt is probably not possible.

The only important thing is that the router supports external antennas for 5G and 4G.

Thanks a lot.

AFAIK there are no 5G devices supported by openwrt.

5G + router....

There are some kits I've come across on ebay and other places but, as a prepackaged off the shelf option it's not likely unless you're going through the provider for FWA service.

Huh? There are plenty. But few are plug-and-play. USB connected 5G modems are similar their LTE cousins. But the power requirements means careful hardware composition, with both a high current 3.3V
supply for the m.2 slot and enough cooling. And wwan configuration can still be somewhat messy in OpenWrt. But this isn't any different for LTE.

And there are fully supported prebuilt 5G routers. At least one: https://openwrt.org/toh/zyxel/nr7101

@bmork I presently use a Huwaei B818-263 in bridge mode connected to an RT3200. I wonder how a device like that might compare to the B818-263? I get pretty decent LTE connection stats already with my B818-263 (just using indoors):

The one that is running OpenWrt is currentlu placed on the basement floor behind piles of fire wood. Not much use in testing signal strength there....

I have one mounted outdoors, but it is running OEM firmware (this is a test device for daytime job). It's currently showing this under some load (necessary to trigger the NSA channel)

AT+QENG="servingcell"'
+QENG: "servingcell","NOCONN"
+QENG: "LTE","FDD",242,01,31A6A04,305,3050,7,5,5,79E1,-82,-11,-51,14,9,140,-
+QENG:"NR5G-NSA",242,01,392,-69,13,-11,643654,78,10,1

OK

If I decode that right, the LTE -82,-11,-51,14 is RSRP,RSRQ,RSSI,SINR. So your numbers are very good indeed. Not sure about the interpretation of the NSA numbers.

For fun, this is the OpenWrt device in the basement (about 30 meters away and 4 meters lower than the first one):

AT+QENG="servingcell"'
+QENG: "servingcell","NOCONN"
+QENG: "LTE","FDD",242,01,31A6A03,113,1450,3,5,5,79E1,-109,-10,-79,14,12,230,-
+QENG:"NR5G-NSA",242,01,185,-100,5,-12,152600,28,1,0'

Intriguing. I spent days optimizing the location. It's on its side adjacent the wall underneath a window.

Resurrecting this thread since that device was mentioned in the ROOter forum. I guess it is one of these: https://ztemobiles.com.au/optus-mf289d/ ?

IPQ4019 + MDM9250-2 - that should be supportable. But someone with the hardware has to connect a console and start figuring out the board specific detail. Start capturing the OEM boot log and the OEM device tree. Then maybe try to mem boot an OpenWrt initramfs for some similar device and work from there.

The MF289D SoC and modem is similar to the ZTE MF286D. But that doesn't necessarily mean that the designs are identical or similar at all.

For adding OpenWrt support for a device, please open a new topic in #devel .
Thanks! :slight_smile:
