The external antenna sockets seem to fairly useless, certainly for MIMO. without having to flash a different firmware which may have other limitations. Telnet would allow sending AT commands directly to the radio modem which should open up various possibilities, like band locking etc. I don't know whether it works on the Three firmware. There is an interesting article here to turn on telnetd on the router. Hence it would be good to get Telnet to work on this box. They seem to have spent more time on a nice design than providing any relevant functions. The web UI is very basic, to put it kindly. I am not entirely sure whether it really uses VoLTE or CSFB, but I was quite impressed to see the phone function working at all.

I briefly tested the phone socket on the MF286D with a 30 year old wired phone and it worked with SIM cards from 1p Mobile (on EE) and ID Mobile (on 3). The MF286D appealed to me since it offers Bridge Mode (I want to keep my Fritzbox 7590 and stick the MF286D in the attic) and VoLTE. I am looking at moving my broadband from a rubbish ADSL2+ to 4G. Thanks to Google Translate, these provide more interesting insights. Besides the Italian and eko.one forum in Poland, I found some more stuff here and here You should now see COM3(DIAG) in ZTE Terminal Software. Select Port from PortManager as LINE1 USB in 'ZTE Terminal Software'.

There are also some Qualcomm usb drivers which work. 'ZTE 3G Phone AT' should be the right one. Good to see that the discussion about the MF286D is picking up in the UK. See COM4(DIAG) -> if anything other adjust drivers in Device Manager. I think this device has a lot of potential but the restrictive software interface lets it down a bit.

I've had a fiddle with the external sma connections to my outside wall mounted bluespot antenna and just swapped them round, download has not changed much but upload has quadrupled which is a sign of good things, its more than the 535 could muster anyway. I'm no expert here but I've done my fair share of flashing LEDE/Openwrt/DD wrt to routers over the years but then its only possible when you have the necessary access available via the above methods. I'd prefer not to brick mine as Ive bought mine outright but I can still return it to Amazon I guess! OEMs do like to lock it out for consumers especially ISP provided routers. That said not all devices have this option, usually only the quality stuff. TFTP is like a method to send files and data - lots of routers have this outside of their main operating system to flash in a new or updated firmware thus making it possible to recover from a "bricked" situation.
