Question About Wireless Range Extenders

Thu Jun 30, 2011 8:23 am

I am shopping around for Wireless Range Extenders since I spend part of my week on a Island with only 2 building locations that you can access the internet. Now the internet service is Hughes.net part of (Direct TV) which is available to all persons working on the island.

I'm looking for a decent Wireless N Range extender that I can hook up in my room to get in the internet with my Toshiba laptop and i Touch. About 2 weeks ago I bought a NETGEAR - Universal Wi-Fi Range Extender and it pulled in the signal at only 17%. Needless to say it wasn't enough to connect so I took it back. The room I stay in is about 50 feet downhill from the building with the internet router.

Here are the ones I looked at so far-

I looked at 3 different models but not sure which one is best for me.

What I'm looking for is one that has the best range and even of it costs a little more. Any advice or other suggestions are appreciated.

Regards, Mike

I know very little about the topic, but since you've not gotten any replies I'll toss in my 2 cents.

The thing to remember about wireless (at least 802.11) is that most countries place limits on the transmission power (off the top of my head I'm thinking it's around 1/4 watt). The only way that I can see an extender working is if it sits within working range of the primary source and then repeats the signal (I'm guessing on a different channel). I'm definitely no expert, but I don't see how an extender can work on the receiver's end if you're already close to being out of range (it's power is limited as is the original source).

Maybe the dish variant has a better shot at this since it can focus both the transmission and reception. The other thing to keep in mind about a dish is that it has to be about 20x the wavelength of the signal to be effective, according to my vague recollections from class a few decades back    . So a 3GHz signal for example, has a wavelength of 1/10 meter, so it would take a 2 meter dish to be effective if my basic math skills are working today. A 5 GHz signal would require a smaller dish, a 1.5GHz signal would need a larger dish.

Really not that much.....move your laptop to several locations (and heights) and check the signal strengths.
When you find a suitable place, that's where you will put the extender (preferably one with antennas outside of the case...) .
