Is there a better option than PowerLine or WiFi to "bridge" two networks together?

I live in a rental, and can't run cables through walls. I want to move my servers out into the conservatory so the noise doesn't bother me.

Problem is that I don't know how to connect back to the rest of the network that lives in my home office room, where my internet connection also comes in.

The distance is only around 30m point to point.

Anyone have any suggestions?

I wonder if I can do something with two old routers flashed with OpenWRT.

Basically I want them to work as a wireless.... wire, carrying all trunked VLANs across.

@mhamzahkhan I did similar to extend coverage beyond workshop building, that is shielding half of my yard.

I've used MikroTik devices, and EoIP L2 tunnel to pass VLAN trunk over WiFi on a dedicated SSID for this point to point link.

I will redo this after winter, but will use station-bridge mode now, which wasn't available back then for their new WifiWave2 driver. So, I shouldn't need the EoIP tunnel anymore, if my understanding is correct.

@mhamzahkhan the speed wasn't great, not bad either.

I cared only for good enough coverage for a WiFi baby monitor, and casual internet use on the smartphone.

The speed definitely won't be a gigabit when trying to penetrate a wall with the signal in your use case.

However, with 802.11ax on both sides - in the AP and in the laptop - I was able to get decent speed through one floor.

@mhamzahkhan I've opened a thread on MikroTik forums for this https://forum.mikrotik.com/viewtopic.php?t=202902.

And, they recommend Wireless Wire. That's the name of MikroTik's product.

It is oriented on outdoors wireless connection. Given high GHz probably it won't be good for wall penetration.

VLAN Trunk over WiFi for SOHO networks - use EoIP or else? - MikroTik

@kravemir I did see the Wireless Wire stuff, but I was a bit worried about the wall penetration as well.

The conservatory is attached to the house, but it was built as an extension to the house so the wall between my living room and the conservatory is very thick as it was originally the external wall.

I'm going to try the flat ethernet cable others have suggested, and see if there is enough tolerance between the door and the door frame for it otherwise I guess I will be trying Wireless Wire.
