good day all..

i need a wifi connection for 300 user and in around 1km range only..
i have 10mbps high speed broadband connection here..
i already bought and configure :

1. asus rt-n66u gigabit router
http://www.asus.com/Networking/RTN66U/
ip - 192.168.1.1

2. tp-link tl-wa5210g - access point
http://www.tp-link.com/en/products/details/?model=TL-WA5210G
ip - 192.168.1.254

3. tp-link tl-ant2415d - outdoor antenna

4. tp-link 3 Meters Antenna Extension Cable TL-ANT24EC3S
http://www.tp-link.com/en/products/details/?categoryid=&model=TL-ANT24EC3S

the reseller said i can reach between 15-50km wifi range with this deployment..
(as shown on the product description)

but it seems my asus router wifi range bigger than this tp-link tl-wa5210g access point..
i already try all wireless mode in this access point but all failed..
i trie set it as ap only, client, repeater and universal repeater.. all failed..

because i cannot get more than 100 meter range even with or without the outdoor antenna..
the tp link access point antenna alignment also dont show any signal...

i think all setting was right because i can access to the internet from my router or tp-link A.P SSID..
the problem is.. the tp-link AP wifi range too low...

i do meet tp-link technical support this evening to help me solve this problem..
but they also dont have a clue...
some say they can get around 3 to 5km range using this tp-link tl-wa5210g - access point..

anybody.. please help me...
