Hmmm... Perhaps I'm not explaining myself very well. In an ordinary situation, I'd connect the tp link device to the D Link one via WiFi, ostensibly to "extend" the coverage of the WiFi network provided by the D Link. (I hope that makes sense?) The TP Link device would then be "extending" or "repeating" the signal from the D Link. I would NOT be connecting the two devices physically via ethernet. Now, consider the above scenario, with the TP Link device inside a faraday cage (the shed). "If" I could physically separate one of it's aerials from the actual device - i.e. by running an extended length aerial cable from the device to somewhere both outside the shed, and with line of sight to the D Link device, theoretically I'd now have (A) My WiFi network extended, and (B) have run the WiFi signal from the aerial, through the aerial cable, to inside the shed. Again, the theory goes that I would disconnect one of the removable aerials from the TP Link device. I would then screw in one end of the extended aerial cable to the connection where the aerial was previously. The other end of the cable would be screwed into the (now removed) aerial, and mounted outside the shed, so that the TP Link device could access the WiFi signal from the D Link device via line of sight. Again, I do NOT wish to physically conjoin the two devices; I wish to broaden or extend the range of the WiFi network I already have, using commodity hardware and an extended aerial cable similar to that shown here https://www.mwave.com.au/product/tplink-tlant24ec5s-antenna-extension-cable-5m-aa81188. Is this possible? Please, let me know if I need to add further to the explanation.
