hi yall im a highschooler and i just got myself a notebook and turned my little crappy house wireless.

well the thing is i live RIGHT beside my school. there is a field beside my house then the school. is there anyway i can use my wireless netork from my house at school. i would figure that the building is about 400-500 feet away. i was wondering if i can use a repeater (if that exists) to send the signal over that way. and to do this i figure i will need my wirless hub that sends the signal through about 20 feet to get to the computers that are going to be wirless and go to something that i can use to send the signal to my school. i think that even if the signal might not be strong enough i can get a directional attena outside my window that would give me the db boost.

im sorry if that sounded confusing this all came to me it 1:30 in the morning.

p.s. i wont be able to test it in the signal in the school because it is summer but i can test it around the school and i have a keychain signal detector.

What does your school administration have to say about this?

Yep, misread your post, and consequently your intention. Yes, you could use a repeater. You would almost certainly need to add a directional antenna, probably a yagi, with some pretty decent gain on it. That would be primarily for transmit however. You'd need something similar if not the same on the other end, whatever you would be using over there. A standard wireless client card isn't going to work.

ok i think i understand what i would have to do on the home/sending signal side but im abit confused about the recieving end with the laptop. would i just be able to replace the atenna(SP) on my laptop to a slightly bigger one or do i not have to. i really don't want to have to lug around something that is pretty big at my school. it would probably look kinda odd

and also thank you for your help and what did you think my intention was

If the yagi on the parent AP is bi-directional, and most you would buy would be, it's still enhancing transmit much more than receive. That leaves your tiny little 1 or dB clip-on on the laptop to try to get back home. At 4 to 500 feet that's asking a bit much. You can try it. You probably can get an association if your yagi is pointed well. I'd look for about a 12-15 degree beamwidth and horizontally polarized antenna from the AP, but your performance would likely be poor. With wireless if you have line of sight you have a shot, but prepar to be dissapointed if you maintain the original laptop antenna.

this should be the last question from me

i know that the laptop atenna sucks is there anything i can replace it with that can work. i would like a atenna on this side and not a dish. if you have any recommendations that would be great. and it would be even better if the attenna works like a stereo systems attenna where it collapses into a smaller size.

in other words do you know of any good collapsable attennas

and i know i can not spell attenna i don't do that great in english

A dish is an antenna, just for clarity. Some PC laptop cards will have detachable antennas that will allow you to attach a different antenna to it, using an adapter and pigtail usually. No collapsable antenna that I am aware of but I don't do day to day wireless installation anymore. Perhaps there is something out there that will work for you. Google it.

yeah i googled it and found out how to make a collapsable attenna. it mainly just folds up.

anyways i set up my house side now and i can detect my network most places around the school so i should be fine.

thanks for your help
