Questions regarding wireless N routers/adapters

by rcs0926 / January 14, 2010 6:24 AM PST

1. If a netbook is equipped with a wireless G network card, will using a wireless N USB adapter upgrade the wireless capabilities of the netbook?

2. If I have wireless G devices, will switching to a wireless N router allow these devices to get a stronger signal from farther distances?

3. Assuming a wireless G device can be upgraded to a wireless N device with a USB adapter, will the wireless N device have an easier time getting a stronger signal from a wireless G router from farther distances?

Thanks in advance for you answers.

1. You would think so.

2. No. I'm having more luck with setting N routers to 802.11b/g mode. Your mileage may vary.

3. They claim such but in practice it matters about locations and interfering signals than N or G.

1. Only if you get a Wireless N Router. Best if you get a router and adapter that broadcasts 2.4Ghz and 5Ghz simultaneous (Dual Band).

2. No. Best to get wireless high-gain antennas that boosts your signal at least 7dpi or more (higher the number the better) from both your Wireless G router and Wireless G adapter.

3. No. There is no difference with N adapter to G router ?vs- G adapter to G router. Also USB adapters do not allow you to add high-gain antennas to boost the signal and pickup.

The problems with today?s Wireless N 5Ghz ? Wireless N 5Ghz technologies are currently designed for speed rather than distance. With wireless 2.4Ghz you can add high-gain antennas to boost the signal and pickup. But getting Wireless N 5Ghz high-gain antennas to boost the signal is also hard to find. This is because of the technology with wireless N makes it harder for high-gain antenna manufacturers to design their high-gain antennas and still make a profit. Hopefully in the near future there will be standards for Wireless N. That should make designing high-gain antennas for 5Ghz wireless N easer.
