Hi

(Dell 1450)

My plan is to use one of these

Does anyone know if this will work and what range id get after the mod
im not sure if that is actualy a u.fl connecter on the board
can anyone confirm this?

Er, why are you doing this - do you need wireless at the end of your garden or something? The Dell is a b/g wireless, have you thought about using N instead? Iirc they have greater range.
Also the delivery on the yagi - 23 working days - thats almost 5 weeks :0

Well basicaly i live in a hostel with no phone line etc
the only way i can get wifi is from some unencrypted wifi across the road from me
since im on 3rd floor i just need a bit of a extra boost from the adapter
Also im a bit straped for cash atm so im doing this with cheap parts that i can get ahold of
i dont mind waiting for a bit for the parts realy

Using a directional antenna such as the Yagi should boost your reception distance considerably. It basically will turn your reception bubble from spherical to a elongated ellipse. A good yagi will allow hundreds if metres line of sight. Whether this £5 item is a good yagi remains to be seen.

I've seen a few homemade ones on YouTube that supposedly work well including cantennas and one made out of White foam plastic and copper wire.

These yagi seem quite small, I wonder if their listed gain is an exaggeration.
