Why isen't my WI-FI working?

Question

I have sort of an older dell, and yesterday just got wi-fi.

I hooked up correctly and everything...I added a password and did all that.

Then I went on my lap-top and for a second the wi-fi worked so then i tried to go to Yahoo.com....then all of a sudden it said it wouldn't work.

It also was working on my DS.

I typed in the password right on my laptop that didn't work.

and I do belive my laptop supports wpa/wpa2

(if you know what i mean.)

i got linksys for my wi-fi.....

Also..the wi-fi keeps saying "signal streach: excellent"

and then chaning to "no connection" or something like that every 10 seconds or so.

Its not working at all.......

Please Help!!!!

Answer 1

Try removing the password on the router....when everything is okay...Put on the password again...It happened to me before

Answer 2

make sure your wireless card on your computer is on.

Depending on the model, it could have a physical switch to turn the card on/off (a benefit of this is, when you're not using it, it will save battery power) or a button (usually in the F keys) that, when paired with the Fn key, will do the same as the other switch. If this is the case, it will look something close to this-->

If that doesn't work, then maybe it's a problem with the actual router. Depending on where & when it was bought (usually, the warranty covers the first year), then maybe you could return it and try a different brand.
