How far can a wifi signal travel? Got a question on it...

post #1 of 35
Thread Starter 
How far can a wifi signal travel? My aunt just got a laptop and has wifi at her house and wants to use it at her's dad's house like less than a mile away. How good or if any signal would she get over there? I've never heard of anything like that except for like maybe 300ft-500ft from my house. But my laptop is newer than her's probably lol. So, anything you can offer to me for when I call him up and tell him what he shoud get?

Over 9000.

I would say a maximum of about 150 ft if the router is on the first floor. Maybe 200 if it is higher. But it will not be possible to go as far as you need without some serious equipment.

You'll need 802.11n, an omni-directional antenna, clear line of sight, and lots of luck.

Otherwise, you'll have to resort to proprietary tech (expensive).

Two things:

1. How powerful is her router (G, G+, N, N+) (N+ allows travel of up to 300m)

2. What card has your laptop got? (G, G+, N, N+)

My macbook is N, so this allow a pickup of a router about 200m down the road, with a connection of 150mb/s

Hope this helps

That's what I was afraid of. They've got an antenna, would there be a way to extend it and mount it on their roof for farther range or something, but would that be cheap? And they've got a ton of trees around them, so the line of sight is another issue.

My uncle bought a G router I'm sure of, but he can take it back to get an N router if her laptop card would accept it. Most likely it won't as I think she got it off craigslist for like $80 lol.

^^ People with (cheap!)homemade antennas and a clear line of sight have reached several miles with off the shelf AP's and adapters.

Cut down those trees!

If you mount an antenna on your roof and they have an antenna on theirs, do you get LoS then?


Otherwise, it probably won't work.

They probably won't mount something on their roof. And where is my laptop coming into this lol.

I think the best bet for her is to piggy back off a closer wifi connection closer to her dad's house.

Ok, just called him. Her laptop is new, just bought yesterday, so it will accept N type. And they bought an N type router. Now, here's the other thing. they wanted to hook up his desktop wirelessly to it, but I believe his is a G type. All I would need to do is hook the N type up to the G router correct and that would serve both computers, right?

They are in seperate rooms as well. Would the N type be able to feed the G router wirelessly so that his computer is accessable or what?
