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!!
You may do well to obtain an external antenna, either omni-directional or directional antenna (if you know for certain where your nearest cell antenna is, and can point it there with a clear line of sight). This antenna would need to be mounted outside your home or office.
That tiny connector there should be called an “SMA” connector, and the specific antenna you need will depend on which cellular technology you are on, 4G, LTE, and so on.
