Review on 📶 Alfa AC1900 WiFi Adapter - High-Speed Long-Range Dual Band USB 3.0 Wi-Fi Network Adapter with External Antennas by Tim Beckett

No difference to those with two antennas. Same signal level as dual modules. At least this one stayed on and didn't turn off from time to time. I have a WiFi cable right in front of my house and I'm looking for a solution to connect it! I can literally go beyond 50 feet from my location and intercept a very strong Wi-Fi cable from my phone, but Wi-Fi modules with large antennas can't do anything but pick up a weaker signal or drop a better connection. My building paid a flimsy telecom company (Frontier - HORRIBLE!) for exclusivity which I hear is illegal so I don't have the pleasure of getting cable that is cheaper and MUCH, MUCH faster! Instead I should be held hostage by this company who raise prices at will without explanation and they do whatever they want! All I needed was Wi-Fi to accommodate it. This one claimed to work up to 500ft, but it took me 100ft at best and nothing! Tried extension cords but they weaken the signal. I tried powerful PCIe cards, the signal is the same. I tried big dbi antennas - it helped but nothing. I tried HD antennas but extending the cable ruined everything. My last try will be to get a dual antenna again, but this time try a long USB 3.0 cable! Since I can't improve the signal with an antenna extender, I try to place the module closer to the source instead. Unless Frontier installs something to interfere with the signal (I know they have a habit of blocking or unplugging the cable when people get their "service"), there shouldn't be any reason I can't get that signal can! This impressive looking device with 4 antennas could not be realized and was too expensive to maintain as it was no better than half the price - at least for MY needs.
