Internet signal booster Device concept (For example, if the main internet device is on the ground floor and the signal is weak or not reaching the upper floor, this device will extend it to you). Honestly, I tried the device and it's excellent, and its settings are very easy without complication. Among its features are dual bands 2.4g and 5g, and you can connect it wirelessly, or wired if you prefer. """ The device does not take a SIM card """ Device condition (New, unopened from its box)
