strong wireless signal... loading lags bad

[paulmpianist]

I have two PC's side by side. The landlady had a problem and was re-setting the modem a few times before I found she had her wireless turned off on her laptop.
So now that the signal is back to where it was... one of my computers is very slow. It will load a page ever 20 minutes.. maybe a second page, but then everything hangs and nothing will load.

It is an ENgenius wireless antennae and it worked great before. I get a good wireless signal on this PC I'm writing from now.. its a cisco. if I want to get a signal from an ipod or an iphone it works ok too.
so the one computer won't use the signal it has very good. All the stats look good in the Engenius interface, but just long waits for when it feels like loading bytes.

thanks for any tips.

one more irregularity... my Local Area Connection Status (ITS Windows XP) has a yellow exclamation point on it and it says limited or no connectivity, but that is only between the two computers (I think) but the network between both computers works fine. I can shuttle files back and forth between computers.
Also the LOCal Area Connection Status message says "this problem occurred because the network did not assign a network address to the computer. but then the network connection details windows opens with an IP address and a subnet mask number too. but no default gateway and no DNS Server or Wins server.

now I found something I never found before in all the 5 years or so I had this great computer. There is a diagnostics tool that runs tests. It says "Connection test passed" but in the list of items in the test there are three more exclamation points... one for "no gateway available for this connection" one for "no DNS server is available for this connection' and one for "no WINS server is available for this connection" also a red X for Ping Network 169.254.etc.etc. failed

Did you try reinstalling the wireless driver?

thanks... yes I did that... I'm looking at the lights blinking on it.... everything shows good connection even once in the last couple of days I had a youtube video streaming which was a lot of action for this wimpy connection. sometimes I've noticed these things heal up, but not yet... its very scant of bytes flowing.
thanks for the reply,
