I had used these on my own router and was successful. So naturally when a friend asked what I recommended, I ordered these for them. They're not computer savvy and installed with no problem. Their WiFi signal is now successfully reaching areas on their property that were previously dead spots.

The antennas did work and increased my signal.. not much, but enough to reach my bathroom where I didn't have any signal at all... Note if your access point has two antennas make sure you change both..

I got this product like 3 months ago to get a better signal at a room locate just in the opposite corner of my house about 60ft, separated for one block wall and 3 sheet rock walls. it helps improving the signal reliability because it used to "fall" every time we use the microwave oven. but the speed of connection didn't get any noticeable increase ???. I'm shopping now for a new "N" wireless router.

1.0 out of 5 stars Don't bother buying this antenna
Reviewed in the United States on October 24, 2010
Verified Purchase
This antenna does not increase range or connectivity in any way. Brand name antennae work better no matter their size...size really doesn't matter! In short, don't waste your money on this product.

Update: I'm sorry not to be helpful to all who read my review...to be more specific, I have tried this antenna on 3 different devices without any noticeable difference in speed or signal strength. In fact, upon use on an internal wrt54g adapter card, the signal strength dropped. I then chose cisco brand antennae with definite improved signal range and reliability.

Achetée pour remplacer mon ancienne antenne wifi cassée, exactement le même model, sans le "ALFA" dessus,

Le signal est comme l'ancienne antenne, voir un peu plus stable que le rafistolage que j'ai pût opérer en attendant,
Cependant, j'ai tout de même l'impression que j'aurais due investir dans une "double-antenne", ou autre afin de couvrir une zone plus large ^^'

Pas déçue pour autant, surtout au niveau rapport qualité-prix! (9dBi)

Con esta antenna he cojido unas 10-15 redes mas, el alcance es muy bueno y hace su trabajo sin problemas, por notar que tienes que tener un adaptador de Wifi que pueda darle poder a esta antenna, veo a gente decir que no hace nada pero es mentira, lo que passa es que no puedes poner un adaptador de 10 euros y esperar que coja 300 redes, el adaptador tiene que tener MW para que la antenna funcione a la perfecion.

5.0 out of 5 stars Antenna straordinaria incredibile sono perplesso dalle sue prestazioni!!!!
Reviewed in Italy on September 27, 2019

Fa la differenza questa e un ottima antenna io la uso sul mio drone fimi A3 ma non sono ancora riuscito a trovare il suo limite all momento sono arrivato 2.2km e il segnale era all massimo senza cali durante il tragitto e alla base il drone arriva a 1km con fatica e varie perdite di segnale!!! Sinceramente oltre le mie aspettative perché non ho ancora raggiunto il limite e dubito di riuscirci perché con le batterie e senza vento dovrei avere un autonomia di 3km ad andare e 3 a tornare e tanta adrenalina sperando di non incontrare vento!!! Quindi in sicurezza non andrei oltre 2.5km!! Quindi questa antenna e straordinaria!!!!

5.0 out of 5 stars Poor WiFi signal strenth? Upgrade to this Antenna.!
Reviewed in the United Kingdom on April 24, 2018

Wow! 5* to Alfa on a decent omni directional 9db Antenna that actually works!
I bought 4 different products, a directional ariel from Alfa of 6db, junk!
A 16db omni aerial from China, junk! Also, a 25db high gain Yagi directional aerial. Not arrived yet from China.
Don't waste your money in desperation, like me, trying to get a decent WiFi network connection. Just buy the Alfa 9dbi Antenna. This nearly doubled the amount of WiFi strength I was getting with the 2.4ghz Alfa aerial.
If your a penetration tester or want to use it for wardriving, then this is the one for you.
