Extending wifi to garden office

[#1]

Hi, we just built a small garden office which is installed with electricity and an ethernet cable that runs from the router in the house to a socket in the office.

I currently have a netgear wifi range extender that I've connected to the ethernet socket, but the signal is still pretty patchy (and dropped out completely half way through a meeting today!).

I was looking at a Deco mesh extender to give me reliable internet out in the office as well as improve the signal upstairs in the house — I just wasn't sure if it would cover this distance (the office is about 120ft from the original router).

Someone suggested a powerlink adapter instead/as well? But do I need both if the office has a direct ethernet connection?

Any advice would be much appreciated. Thanks.

As you've run ethernet cable you should get a solid signal in the office. Try connecting a laptop by ethernet and then run a speed test. If it's poor, there could be a problen with the ethernet cable from the house.

A Wi-Fi extender will be looking for a Wi-Fi signal to extend. Can you put the extender in Access Point mode ?

Do you know someone with / have an old router? Turn off the DHCP, plug into the ethernet and set it up. I used the instructions here, even though mine isn't TP. Most routers have the same functions, you just need to find them in the settings.
