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.
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 ...
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...
Summary: honestly expected much better than this and things like this should probably be sold in 2 packs aswell now for wireless n
Pros: did increase signal strength.(by a very small margin)
Cons: wish these were cheaper the ones that came with my wireless card were half the size and perform within 3% and they are only 2dbi. these are 5dbi so thick at the bottom that they touch and can only be bent at certain angles or they hit each other allowing no more movement
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.
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.
