thanks for your replies.
I tried the wired connection on same subnet, does not work on any of the ports.
Microtik support said I should upgrade the routerOS and do a reset, so I upgraded it to 6.43.8 (the latest stable version) and performed the reset. Still no joy.
Which LED's should flash is confusing, I was initially seeing the SFP+ flash and thinking that was the reset, so I tried holding until the 10 ACT LED's flashed before releasing. Still no connection in browser to 192.168.88.1, still no MicroTik wifi network.
I just want to run 'QuickSet' and get the thing going, as I was assured by Microtik sales it would do.
While doing the router upgrade via Winbox, I did notice the top menu item was 'quickset', it is not the user friendly version that is expected from reading this manual: https://wiki.mikrotik.com/wiki/Manual:Quickset
I gave it a whirl anyway...
First note - top left - choose the correct router mode, for me it was 'Home AP Dual'. Set the country and a couple of IP address stuff until it was happy to apply it.
Ended up with a WiFi network, but obviously got stuff wrong as can't connect to it, seems DHCP is failing to dish up addresses but I did set it to use a range on same network, so still no QuickSet, get connection timed out errors.
Got to prove I have reset working, as doing another reset removed my MicroTik wifi network.
But now can't even connect to it with Winbox
Even after resetting from backup RouterBOOT loader by holding reset as plugging power back in doesn't let winbox back in.
Very frustrating, such a waste of time for such a high end business grade product (my opinion is changing on that currently).
