Check your firewall and security setting...ie WEP/WAP make sure you've the network key to be able connect also make sure your part of the right workgroup.

I have an Acer Aspire 5570 running Windows Vista Home 32 Bit. I had a similar issue with my wireless connection where my signal strength would only reach between 50% and 60%. I spent hours troubleshooting my router and the wireless settings on my laptop. I even installed an old external wireless card that I had from my old laptop. When I used this card, I got a good constanst signal immediately so I knew it had to be the internal card itself. I ended up changing to a different channel on my wireless card's advanced settings and now I am at 99% signal strength. Also check the wireless settings on both the router and the card to determine if it transmits over B, G, or A. I made changes in my router to broadcast only on wireless G and this helped a great deal as well.
