My friend is moving into a new house and wants to set up a wireless network.
I have suggested him to use D-Link hardware because it is one of the best performing routers out there.

However we have some questions. He will have 2.4ghz phones in the house and doesn't know if he should use the G band or the A band. He was even perhaps thinking of the D-Link router that has A,B, and G bands. He still has some B network cards that he could still use. He will also be buying some more as well and he will need good range so probably G is what he will be buying. With the 3-band router...can one operate at all three bands at once or only one at once?

Also, he will need to spread the signal throughout the house. I was thinking of recommending him to buy a big omnidirectional antenna that he could hookup next through the router instead of buying multiple access points. We are not sure on the feet calculations but he will probably need some signal boosting so perhaps a different antenna may be the way to go to spread the signal throughout the whole house. Thankyou.
