Hi All,

I have a garden outhouse which I use to work in. I have a Mesh Child Node in there but the WiFi is still quite flaky.

My main Router Node in the the front room of my house (connected to the ISP Internet). I ran some Cat6A cable that someone gave me under the floorboards & into the next room. I need to extend this into the garden outhouse so I can connect it to the Mesh Child Node there & get stable Internet. The garden outhouse is about 30 metres away from the rear of the house.

I bought some Cat6 cable (as Cat6A was very difficult to terminate into RJ45 plugs) & a Ethernet Cable Joiner. I plan to use this joiner to connect the Cat6A cable to the Cat6 cable & run it all the way to the garden outhouse & would like to ask, if this will work properly or if I am missing something or doing anything incorrectly?

Please see diagram below,

Many Kind Thanks!

No issues with CAT6 vs CAT6A.

You may already be aware, but just in case…

Running Ethernet underground to another building can introduce ground potential issues, which could fry your remote node. There are opto-isolators you can buy (not all that expensive) that’ll reduce that risk.

Unless the OP has a substation, high power radio transmitter or electrified railroad next door, running the CAT6 in the ground shouldn't create a potential difference that can't be handled by the transformers used in Ethernet ports.

I would recommend running the CAT6 in some sort of conduit - plastic would be fine.
 
Hi All,

Thanks kindly for the input - looks like I have got things right then with regards to how I have planned the wiring as per my diagram above - really good to know as now I can proceed with confidence.

Thank you so much!
