hi all,I`m new here..DLINK sent me..new guy old problem..

http://images.thetechguide.com/forum/public/style_emoticons/<#EMO_DIR#>/laugh.gif\' class=\'bbc_emoticon\' alt=\':lol:\' />
I believe my wifi access point signal is weak enough to not let Internet Explorer load a page.
It will,however,download Windows update,I saw it happen wireless-ly.It is unsecured.
I get the message:"limited or no connectivity",and that I may not be able to connect to the internet,
but I can see the DLINK program shows that I am connected.
I can see that I am sending 4x more bytes than I am recieving.
Properties will show that I get a 50% signal,[low/very low], the access point is 54. mbps strength.
I have not tried a real wifi hotspot yet, but the question is :
"do I have a reception issue,or an old laptop issue?"
Below I will specify what I do have:
celeron 933mhz/256mb.ram/60.mb free space
DLINK dwa-652
windows XP s.p.3
thanks for your help!!
BIlly
