ZTE MF286D 4g router

I have a Three branded MF286D router with a Three paygo sim. It has worked perfectly for the last 3 years.

Current software is B08 which is quite recent.

Since B07 (which was released earlier this year) the 4 ethernet ports no longer work, the rest of the router works fine with wireless connections and the phone RJ11 port also still works.

I used to have 3 ethernet connections for smart TV, a laptop and the SKY TV box.

Unfortunately there does not seem to be any release notes available for the software versions.

Has anyone else had this problem?
 
I gave my MF286D to my daughter recently but vaguely remember having a couple of device connection issues over the months, but that would have been on WiFi. I think I simply set the TV to a static IP, specifying the DNS & gateway and got it to work. That would indicate a DHCP server glitch on the router.

I'm inclined to think your problem is not related to a software release (as you've had two and if the first had caused the problem it would surely (!) have been fixed in the second).

The Ethernet ports on the MF286D each have a green LED which is lit when connected to a 1Gbit link (highly likely on your laptop if fairly recent). Do any of the Ethernet LEDs light up when the port is connected?

just tried my MF286D (on Three stock firmware B07), no issues with wired LAN. Put in an old Three SIM card and the router upgraded itself to B08.

Thanks for the response, I am beginning to think it is a hardware problem myself.

When I plug in an ethernet device the green light flashes from time to time, I beleive this is probably a DHCP request and the router does not reply.

OK, that's useful to know. You might want to try a full (factory) reset if you haven't already. I presume you can still get to the router's web page via WiFi, so should be able to do it from there.
