Summary: The motherboard in my mid-tower has WiFi built into it and connectors for two antennae on the backplate. The dual antenna that came with the motherboard was some kind of cheap folding dipole thing, so I wanted to replace it. Having these two nice lookin' antennae attached directly to the backplate is so much better than a dipole antenna magnetized to the outside of the computer case.
Pros: Bought two antennae, plugged them directly into the two connectors on the backplate to my mid-tower. My Windows 7 computer liked its new antennae so much that it started ignoring my CAT5 cable and connected to the internet via WiFi! Sheesh! Computers these days will chase after any new equipment that catches their eye! By the way, I didn't detect that change for a couple of days and my internet services seemed to perform at just as high a level as my CAT5 cable connec...
Cons: After my Windows 7 computer found the new antennae, I couldn't convince it to prefer its old CAT5 cable connection. After hours of attempting to prioritize it to favor the cable connection over the WiFi connection, I found that Windows 7 refuses to ignore WiFi as its primary connection. I finally disabled the WiFi in order to get Windows 7 to finally connect to use the cable connection. Not the antenna's fault, they can't help it if they're pretty! Zero Eggs deducted.
Summary: My desktop is only getting me 1/3 internet speed when compared to laptop in the same room. I was hoping this antennas will solve the problem and it slightly improved my internet speed. However, the overall performance gain wasn't enough to make me think my $16 (since I bought two of them) was well spend.
Pros: - Slightly improved my internet speed
Cons: - Performance gain doesn't justify its price tag
Summary: I purchased 3 to replace the 3 x 3 dBi antennas that came on my TP-LINK TL-WR1043ND Wireless N Gigabit Router but the signal did not improve. It even went down a little according to wifi analyzer on android and my wifi icon on my laptop lost a bar. I gave it 2 eggs because I have had great success with TP-Link equipment but these just didn't do anything for me. Other reviews show that they do work, just not in my case.
Pros: Great price.
Cons: Did not improve my signal at all. If anything it made the signal slightly worse. I am not even sure how that is possible because they are 2 dBi stronger than the factory ones they replaced.
