Extra antenna to extend WiFi range

[alexjimenez1070]

I am looking for a cheap WiFi antenna that will connect me to my WiFi underground I have a shelter off of the house and would like to receive WiFi without running any wires out there. Any suggestions?

Do you have wall sockets there? How about Power LAN Adapters?
Electromagnetic waves can not pass thick walls or layers of earth and still give you a good connection.

There are wall sockets and a ventilation shaft in the ceiling.

So if the shelter is on the same electric network as your house, you can use the above mentioned adapters, also called powerline adapters to put your signal through. LogiLink, Linksys, Netgear and larger router manufacturers usually also have powerline solutions to offer.
Here is one https://www.amazon.com/TP-LINK-Powerline-Pass-through-TL-PA9020P-KIT/dp/B01H74VKZU/ref=as_li_ss_tl?ie=UTF8&qid=1471790573&sr=8-1&keywords=TP-LINK+AV2000&linkCode=sl1&tag=nerdtechy-20&linkId=e8f1509ae00760229775f35bfe718add

Okay thank you. Also if I wanted more ports could I connect a router or would I have to purchase an adapter with more ports.

It is possible to hook up a router or you can buy more modules to the powerline kit. Both works.
