My scenario:
* Starlink router installed in metal spray foam building
* WiFi - very strong inside not so much outside
* 4 - Security cameras ~ 40' - 100' from house
* closest camera has 60 dBm furthest has 81 dBM
+ 65-70 dBm is acceptable
* lived in RV while house was being built w Starlink router in the RV. it powered a camera ~300 feet away.
* the metal building is blocking the WiFi range.

Looking for a completely wireless solution to extend my WiFi outside of the metal building.

* I have tried a TP Link directional wireless extender that is an interior install that you put in a window. It didn't work well.

My continued research is pointing me towards a WAVLINK exterior extender.

Does anyone have experience w this situation? Your solution? Any assistance would be greatly appreciated.

You can run a weatherproof wireless access point with an outdoor rated cat6 cable from inside to outside. Youll need to probably add a router internally from the the starlink as I dont how many ports your setup has but its doable. What kind of range you get Im not sure but your metal building is acting as a shield to the outside as youre finding out and is common. You must go from the inside to the outside with a new wired access point to get that signal out there. Your results may vary tho.

Basically what Onemangoon said. Or move your starlink stuff out of the giant faraday like cage and run wires inside it to an indoor WiFi router to connect the indoor devices to and the outdoor ones can the starlink like you did when living in the rv.

I went down some AI prompt rabbit holes on building remote wifi nodes on property to extend wifi and ultimately to replace data plan/ cellular cameras with wifi cameras like nest or reolink. the metal building will be a big hurdle- those block signals- I think if you can run a coax or certain type of ethernet cable from your router and mount an antennae on the roof of your metal building, you'd open up a lot of possibilities- you'd immediately extend the wifi range, but you could also mount some nanobeam or other tech to a node elsewhere on the property and get cameras out even further. or, what I was looking into - get a HaLow hub (which is long range wifi) on the roof of your building.

What version StarLink access point do you have?

Unlike the earlier versions that required an adapter to install hard wired network components the newer (I think V3) router does include built in ports. Shoud easily be able to install an access point outside that will mesh with your network.

I'm honestly at the edge of my network knowledge.... But I've used some of these products in my last job (I just didn't have to do the configuring).
I used the AC Mesh Pro and the AC Mesh (the "bunny")
ChatGPT or the Nerdery could probably help with the configuring.

How far away are your cameras? Then how widely spaced are they?
The biggest issue will be power at the remote sites. Most equipment comes pre-packaged with 120V to 12 or 24V PoE, but you can get the appropriate PoE that will run off of a 12V Solar setup.

I've done it. But we ran them off portable batteries as the entire thing was temporary.

Just connect a power over ethernet equipped antennae to the Starlink router and put the antenna on the roof of the building. As long as you have power to the metal building, you can plug in to power the POE there and run the antenna on top. Then use solar panel equipped Nest Cameras or similar.

Kenneth, I have the Gen 3 Starlink.

I am keenly aware that I can accomplish with an Ethernet cable from the router port to an external WiFi extender. I am trying to avoid running the cable and trying to solve via a wireless solution.

The metal building is a Barndominium and, right or wrong, I am trying to minimize penetrations. I am going to try the WAVLINK AX3000 WiFi 6 extender before going the cable route. Several reviews from RVer's, used this extender in the "repeater" mode to wirelessly pick up the RV parks WiFi signal and were successful.

If it doesn't work, package it up and send back to Amazon and go the cable route.

Thanks to all who responded.

Does your window open? If so just use a flat ethernet outdoor rated ethernet cable to bypass under it and a POE access point outside. No holes needed. I have done this with both RJ45 and ethernet before with no issues. Same for feeding a cable out a soffit vent if you have those. Plenty of places usually to not need to drill a hole when you have 300' to play with range wise to get your antenna mounted outside and ethernet cable back inside. It will be exactly what you need with an omni directional POE AP on the roof or similar.

As mentioned before you built a faraday cage, an rv camper is nothing like that where most of those reviews will be based from. Fiberglass vs metal is drastically different for wifi signal degradation.
