Pros: I have a TP-Link TL-WDN4800 WiFi PCI-e 1x adapter in my desktop. This wireless card is fairly expensive, sometimes up to $70 if it's not on "sale". It comes with three external antennas. I also have a Apple AirPort Extreme wireless router. My PC sits three rooms away from the router, and it gets a fairly good connection at -63dB. For your information: Anything between 0 to -30dB is considered excellent, -30 to -60 to be good, -60 to -80 to be passable, and anything past -80 is considered unreliable by most WiFi 802.11 2.4Ghz standards. I wanted an improvement, so I purchased a Hawking external antenna to replace one of the three antennas that are on my WiFi card (since the Apple AirPort Extreme cannot support external antennas). The results were noticeable, but not by much: using inSSIDER to run a benchmark test, I was connected at about -59dB on average. That's an improvement of 4dB, which is fair given the specifications on this antenna. It really doesn't give me a "more solid" connection, or faster bandwidth. However, the product does what it stated it would; give me up to 7dBi gain depending on configuration. Also, I went from seeing 6 other WiFi connections from my neighbors to now seeing 11 other WiFi connections, so it's definitely a noticeable difference. However, you should probably look for a higher gain antenna if you are trying to fix a non-existent connection. This antenna provides minimal gain.

Cons: Minimal gain of only 4dBi when connected to 802.11G 2.4Ghz with antenna on client-side.

Pros: Cheap

Cons: This product sucks... It gave me no real boost... I actually have a weaker signal with it... Waste of money

Pros: Bought this antenna for my extra desktop in the upstairs bedroom. Since the router is on the 1st floor on the whole other side of the house, I would get 1-2 bars average or sometimes no signal at all due to the terrible antenna that came with the desktops wifi card. After I replaced one of the antennas on the wifi card with this, the signal strength shot up to an average of 4 bars. Although the omni-directional antenna was not needed, I thought it better because if my internet was ever down I could pick up the neighbors ;o.

Cons: None so far. Only owned for about 3 days however so we shall see.

Overall Review: Good for any desktop with a wifi-card where you would be wanting to pick up signals from all directions. Be reminded though, if you have this connected to a router on the edge of the house, you might not want to get an omni-directional antenna because half of the signal would just be going outside. Best for locations in the middle of the house.

Pros: Looks nice.

Cons: I have a weak wireless spot in my home where the signal fluctuates between 20% and 50% on average. It's just enough to cause problems browsing the internet and downloading anything (packet loss is too high), and gaming is impossible. I bought this thinking it would give a modest boost to my signal in the back room and hopefully rectify some of my problems but..... this product simply doesn't work as advertised. When connected to a computer the signal from my router actually got worse (dropped from 55% with the 4 inch included antenna to 27% with the Hawking).

Overall Review: Spend a few extra bucks on a signal booster or repeater, you will have much better results.

Pros: huge body of wifi floats around this booster it is like a lake of wifi in your house and you are a boat in the middle Alex Cucu, of Willoughby Hills

Cons: none

Pros: Outstanding product, worked great. Simple installation and increased my network strength as desired.

Cons: The base is not very good for mounting on a vertical wall.

Overall Review: Purchased this as a replacement for an overcomplicated range-extender unit and was very happy I did. This is a much simpler solution and that means much more reliable and durable.

Pros: looks decent.

Cons: This thing didn't do anything the default antenna couldn't do. No signal gain. No boost in reliability. All it did was take up more space on my desktop.

Overall Review: I can't comment on how well it'd work on the router-end of things, but used with a wi-fi adapter, it's not worth the price of shipping.

Pros: Fair price

Cons: Not as great as my other antennas, line of sight only. I got better reception on my regular antenna that my dog had chewed.

Overall Review: Save your money and build a cantenna, or find a good 10db+ amplified antenna
