A wireless router (detachable antena) with USB port in it

Hi,

My friend is looking for a Wireless Router to connect A PC (Wired), 1 Lappy, 2 mobile and one PS3.

His priorities are;

1. Detachable antenna OR 7dbi Built-in Antenna
2. 150mbps
3. USB connectivity for devices like external hard disc or printer. (optional)

Do let me know if you require further details.

Regards,
Adhip.
