This is only marginally related to specific Mikrotik hardware, even if schemes 2 and 3 could use a GPERx4 (GPERi14) and the currently installed TP-LINK Access point will very likely be replaced by a cAP or wAP (WAF shouldn't be a problem as the current TL-WA1201 has been accepted).
The current setup is a (basically) a "FWA with outdoor CPE" as installed by one of the leading ISPs in Italy (TIM).
A LTE outdoor modem/router is installed on a pole on the roof, powered by a PoE PSU placed in the attic. In the attic there is also the "main" router (ZTE H388X) and a connection (physical CAT6 cable) to the TP-LINK TL-WA1201 which is PoE powered (passive 12V) which is in a corridor. There is another connection (physical CAT6 cable) to another room on the floor under the attic.
Now, more than seldom (but not really often) there is the need to power cycle any of the three devices (Nokia, ZTE or TP-LINK) because something is not working. Usually both the ZTE and the TP-link can be rebooted remotely from the network, but I have not access to the Nokia to reboot it from the network, I need to physically unplug the power brick from mains.
Lately it is happening more often than before that the one that needs to be rebooted is the Nokia and it is quite a PITA to have to go up the attic to disconnect and reconnect it.
The actuall internet speed the (LTE) coonnection allows is - on average - 30 Mbits or so, in very lucky days (actually nights) it can go 50-60 Mbits top.
In order to make troubleshooting easier (I do suspect that there is an issue with the Nokia PSU but have not yet made tests) and more generally making my life easier for the future, I plan to move the power supply of the Nokia and the main router to the room, so that I have easier access to devices and can plug/replug them if needed.
I know that the bottle neck will be the single connection attic-room, and while it may be possible to add a new connection (another cable) it is not exactly easy to do, and for the moment I prefer not to go into the trouble of it (these CAT6 cables are not exactly easy to pull into conduits).
So I came up with three different schemes (I am attaching them) that could (should) solve the problem, at least temporarily.
Schemes #2 and #3 are essentially the same, the only difference is the way the TL-WA1201 is powered (from mains or from PoE).
SInce the TL-WA1201 is currently running OpenWRT I could - if needed - see if I can configure it as router/access point (as opposed to the current plain bridge/access point) and/or replace it with a cAP AX or a wAPAx.
GIven the actual (low) speed of the ISP connection, even if I downgrade the attic-room connection from 1Gb to 100Mb (scheme#1) it should - I believe - make not that much difference,
The other 2 schemes should be better, and using the GPERx4 I would have the possibility of power cycling the Nokia from command line.
On the other hand the TP-Link TL-SG1005P-PD has a function (if it works) to power cycle automatically not responding devices).
Thoughts/ideas/reports of similar experiences would be welcome.
P.S.: only as a side-side note, I did have in the "drawer of things that may come useful one day" a pair of (supposedly) RJ45 splitters, but upon inspection, and even if I checked that at the time I bought them that they were sold as "splitters" they are actually (good for nothing) RJ45 couplers (1,2,3,4,5,6,7,8 of the single port go all to both other ports on the same respective pins), so I had to order a couple of (hopefully) proper splitters (where the 1,2,3,6 of the single port go to 1,2,3,6 of one of the two other ports and 4,5,7,8 of the single port go to 1,2,3,6 of the remainig port).
