Summary: this antenna does what its suppose to, its a cheap way to boost your signal around the house, i would recommend it to others, only concern would be is its much longer than the factory antenna's so it might get in the way if your router is on a desk or shelf
Pros: good price, easy to install, boost signal
Cons: very long antenna compared to stock antenna's
Summary: I use to have 2 or 3 lights on ,in my clear moden ,after I install this antenna the 5 lights are on and have a better speed .just remember to put the modem close to a window to have the better reception .
Summary: I'm an IT consultant (25 years now). I installed this on my mom’s wireless USB NIC. Before swapping out the antenna she would only get 1 or 2 bars and connect at 5 Mbps. After putting on this antenna she would get all 5 bars and connected at 54 Mbps. The speed increase was very noticeable when just surfing the web. I'm so happy with it that I've decided to get 4 more of them, 2 for my router, one for my laptop and one for my desktop.
Summary: I bought 3 of these antennas to attach to my TP-Link router. There's a small improvement in signal strength when I test at a short distance from the router (1-3 meters). At a short distance it goes from -40+ dBm to -30+ dBm. The change is even smaller at a greater distance (10+ m). I expected a greater improvement going from 3 x 3 dbi antennas to 3 x 8 dbi. Good thing that I pricematched and didn't spend too much money.
