hi i have linksys router downstairs connected to my cable modem and i have a second computer up stairs with a wireless pci card thing. iam only getting very low and low signal. how can i boost the signal as cheap as posible or even for free...?
What model linksys router? if it's a WRT54G, you can flash it with custom firmware (Alchemy) that allows you to boost the signal 4-5 times the normal. Other routers can be flashed as well, AFAIK.
You're lucky, that's a great router. Check out this link: http://wrt54g.thermoman.de/ It's going to get a little advanced, but nothing you can't handle. The page that I linked to above is a good starting point, but you're going to have to do some reading. Like I said in my original post, "upgrading" your firmware will add some serious functionality to your router (including; upping the signal strength). Good luck!
Click the link right below this sentence: http://wrt54g.thermoman.de/ Trying out the other wireless card certainly wouldn't hurt, in fact it could solve your problem altogether!
