Sorry for the degeneration into squabbles and such. And sorry if my
original answer was hasty and confusing.

I hope you can get a decent answer out of this thread. What Dan S
said is good advice. Read it carefully, as that's the ticket for a
good long-term solution. With a cheap wireless router thrown in, it
will cost about $200 or so.

If you want to go cheaper then you could try sticking a USB wifi
adapter out the window (protect it from elements) with a long USB
extension cable running into your house. 15' is the max for USB
passive extension cables. Won't give you roaming, but you will have a
connection inside.

This one has been recommended as a good USB adapter for extending your
range: http://www.gohawking.com/store/produ...roducts_id=140

Again, the best solution is probably what Dan S suggested.

And yes, you could buy a standard consumer repeater product as sold by
Linksys and others at your local store, and it might work, but it will
not be weatherized or come with a directional antenna. Generally, it
must be the same brand as the router your parents have and your wifi
security may not work right. You can always try it from a store with
a good return policy....

Cheers,
Steve

Thank you, you guessed it I'm not an expert, and have appreciated the
simpler explanations. DanS you are spot on with your 1, 2, and 3!!!
I'd like to spend $250.

My question though, is there a big difference between 9dbi directional
vs. 7dbi omni? My network card originally came with a 7dbi omni
external antenna and I couldnt get my parents signal with it (it was
probably $5). A geek made me an antenna out of a tin can which worked
amazing, I've been using that.

Do you think the $150 one with a 9dbi directional will get me the
signal when a 7 dbi omni couldn't? Or, since my budget is $250 would
you spring for the $184.99 one with a 16 dbi antenna? Then get a
Belkin F5D7132 wireless repeater and Cat5 cable... then I should be
good to go?

Thank you!

Yes. In addition to the 2 dBi in gain, the omni will have a much more
restricted vertical pattern, and will be less able to reject
interference.

Really? Most wireless cards come with 2 dBi or less (often much less)
antennas.

Sure. Much higher gain, and directional to reduce interference.

I suggest you try a reflector with your current antenna.

It takes FOUR times the gain to DOULBE your distance, 20 a mere
2 dB gain won't do much for you.

Jumping from 7 dB to 16 dB is a 9 dB gain, so that will more than
double your range with gain to spare to offset coax loss.

Would you consider a BBQ dish antenna?

15 dBi gain $35

24 dBi gain $55

Don't forget you cables, and remember your Linksys has a reverse
type of connector.
