i used rtn12hp_b1 for 4 years, full 50mbps wifi with default settings, no tweaking.

50mbps, 2.4ghz is fine... ethernet or wifi... if yr router is performing.

download... dunno what DL u mean, but p2p, it depends on seeds and peers.

if good enough, u should get max 50/8=6.25MBps, maybe 6.5 at times.

if poor seeds/peers... poor, zero even.

if u r consistently getting poor DL speed with wifi, u gotta think another router.

That speed is good la... apa lagi mau?!
