Bro semua, numpang nanya

Kebetulan di tempat baru kita koneksi internetnya via kabel LAN dan via wireless. Untuk pc yang via kabel, koneksi internetnya normal (kita memiliki langganan yang 3 MBPs).

Nah anehnya, laptop yang menggunakan wireless akses poin, browsingnya lambat bangat.

Topologi jaringan wirelessnya sbb:

Laptop --> Wireless AP (WAP54G Lyksys) --> Modem Router

Saya udah nyoba ganti-ganti DNS, baik google, OpenDNS, Nawala, dll, tapi tetap sj browsingnya lambat

Ping ke DNS milik ISP memang kalau sy lihat kurang bagus, baik lewat kabel maupun lewat wireless, ini yang via wireless :

terus terang saya bingung ni dengan soal. Kira2 menurut bro semua permasalahan di saya ini karena apa ya? Apa yang bisa saya lakukan untuk mempercepat akses internet supaya sama dengan via kabel?

Terima kasih
