Quick background. (i'm a noob to this as well which doesn't help)

House refurb and builder was to provide cat6 at the chimney along with Coax.

Apparently the sparky thought I had made a mistake and only ran the Coax.

I can't retrofit the cable now (not allowed ffs).

I've a big site and wanted an access point on the chimney as it would provide wifi outdoors perfectly. I don't now need a TV aerial so I have been looking at POE over coax solutions.

Most seem to be aimed at legacy CCTV cameras and only support 100 base-t or is that more than enough? I wish to access remote off grid wifi cctv and a summer house down the garden with no mains power.

Therefore this seems perfect. TP-Link AC1200 MU-MIMO Wireless Gigabit and the standard is 802.3af/Passive PoE (PoE Adapter Included)

All coax and Cat6 come back to a cupboard so I can pop a switch in there.

Any suggestions as to kit required?

That's a very serious mistake by the electrician, was that written in the contract that you requested Cat6 and Coaxial installing? Why did you go with Cat6 as well and not Cat8? I know it won't make much difference now but if it's a permanent installation, Cat6 might start to be the bottleneck down the line.

You say you're 'not allowed' to retro fit a CAT6 ?

Yes not allowed! As it would now mean running cables outside.

The job was done some time ago. It's not essential but it would be nice to have an access point at that location as I had originally envisaged.

I've emailed the manufacturer of the adapters for advice.

Sounds like a job for powerline adapters.

sorry can't help on what you're asking but is "running cables outside" an aesthetic concern, it might be worth talking to a (good) sparky who might have some creative ideas how to hide or minimise the impact.

Everyone I know installing ethernet Cat cabling (and I work with communication and systems engineers), works with CAT5e at home. The bend radius limitations and cost of going to Cat6 (and beyond) is just not worth it. I would however caveat that by saying they use trunking so an upgrade could be done with a deep retrofit.

Save yourself a lot of heartache and run some UV resistant Cat 5E (copper FTP - foiled twisted pair with drain / earth wire). £16 for 50m up the wall and over your roof. It's practically invisible once laid on the tiles, and the run up the wall will just look like the other wall runs, like BT, power, TV etc - you never notice nay of them.

You can now put a decent Poe wifi entender up there. Having two, makes a HUGE difference.

I have this on a wall 2 stories up:

TP-LINK CPE210 Outdoor 300 Mbps WLAN Access Points

That sends wifi over 100m - works great on a device with a decent antenna built in, like a laptop, but very sketchy on a phone.

However, once I put this at the other end (building with no power):

KuWFi 150Mbps Wireless Outdoor CPE 2KM Distance Outdoor Wireless Access Point WIFI Repeater WIFI Extender Bridge CPE Router with UK POE Adapter

I now get unbrakable, full on, full speed wifi at the remote end. The reason my remote one is different is because it cab be powered by 12v direct, and I power it with a car battery and solar panel. You could put these at both ends instead of using the TPLink.

The link is so strong that mounting it under your eaves would almost certainly work great too.

The cat 8 thing is rather amusing. As is the obsession with Cat 6.

Cat 5e gives you gigabit over 50m, and unless you are planbnign on running a wireless server farm, it will serve you well probably for the rest of your life.

IPCams only need a few Mb to work well.

and as for powerline adapters? - not really a job for them unless the OP wants to run a huge T&E cable to the chimeny and have an outdoor power socket installed on it :-)

unfortunately running a cable is not an option.

However, that KuWFI device! Can it repeat my wifi externally via wifi? I can run 12v DC over the coax to the chimney.

I've heard of devices that do this but never really understood how it worked or if latency was an issues. I presume such devices use 5ghz for the repeat and then then 2.4ghz for the access point??

I'm fairly sure it can. You'll need to do your research but I'm fairly confident.

It shares it's bandwidth between the uplink and downlink. It only operates on one frequency.

Latency isn't a problem.

Is the coax in trunking? Is it in a relatively straight run? Could you tape some cat5e cable to one and and pull it through?

Alas no.

If there was a way of capturing my wifi signal and just repeating it that would be ok. I can put a fair bit of current up the coax.

I just need such a device that will so that and has a DC input.

Check the specs. I'm pretty confident what I've linked will do it. I'm not going to do all the leg work for you ;-)

External cat5/6 out of house at floor level (got a spare on an external wall?)
Buried in tubing to nearest gutter down pipe
Cable behind down pipe to roof level
Cable pushed under tiles into loft to gable end and then drilled out to WiFi repeater location.

I do it for clients all the time with cables, it just takes some thought.
