hi everyone, i don’t know if this is the right place to ask this question so sorry in advance, the thing is i bought a year ago a 4g wifi router snice there is no dsl or fibre connection in rural areas but i have been suffering from the slow internet connection specially if it’s cloudy, raining or there is a massive users pressure, but i’ve heard lately about some type of antennas designed for this type of router to support them and help boosting the signal waves, there are none in my area and i have no choice but to purchase one from ebay but i didn’t do it yet cuz i want your help guys in finding the best antenna that suits me. the device name is soyealink with two antenna ports from behind. THANK YOU!!
