i bought 2 of this device (sxtsq 5 ac) my friend has fiber in his house but i only have adsl so its slow, he is across my building clear sight, i put 1 dive connect to his router and 1 device connect to my pc, the guy who sold me these(local tech company) they told me they will set it up as i want(basically i wanna connect to his fiber via with devices) but when i try it says no cable connections,both device gets power with PoE cables* and there is 3light+signal light but only power light works rn, so no idea what to do after this point. http://prntscr.com/ugi6ws , http://prntscr.com/ugi7cm
