Wireless WinXP Laptop Won't Connect to Internet

Perhaps someone can help? My laptop won't connect to the Internet
through my home wireless network, even though other PCs do.

Here's the setup: One computer, running WinXP Home, connects directly
to the Internet through a USB modem with Internet Connection Sharing
enabled. It also connects (using a powerline network) to a Dlink Access
Point. The computer is set to be the DHCP server -- I think that *has*
to be the case under Windows XP in this configuration, though I may be
wrong.

Other desktops have Dlink wireless cards, also run WinXP home. They get
IP addresses from the DHCP Server/ISC computer and access the Internet
without a problem.

The laptop runs WinXP Pro and has a Netgear PCMCIA card. It doesn't
receive an IP address and reports that connection to the wireless
network is "limited" -- this even though the laptop and access point
are within several feet of one another. If I manually set the IP
address, it reports "excellent" connection to the network. But it
doesn't find any web pages, and can't even open the access point's
maintenance screen. This problem occurs even when I turn off Windows
Firewall on both the laptop and the ISC computer.

Can anyone explain what's going on, please? I've spent hours fiddling
and getting nowhere.

Google a copy of winsockxpfix.exe to repair the TCP/IP stack. Check
TCP/IP properties, advanced button, Options tab, TCP/IP Filtering
properties. Verify that Filtering, if Enabled, is set to Permit All for
all ports/protocols, Apply, then turn off filtering. Set the wireless
to Infrastructure only, uncheck the bit about automatically connecting
to unpreferred networks.

Is this a *broadband* USB modem? If it is, then you will find superior
performance with a router or an ethernet NIC in the host computer.

Q

Hi
May be this can Help.
In General you can debug the Network Settings of a computer by following
these steps.
Step One. Check the Network parameters in the Computer's Device Manager.
Make sure that the drivers are installed correctly; there is No IRQ
conflict, and No Ghost installation. http://www.ezlan.net/faq#ghost
Step Two Verify Basic network setting in the OS:
http://www.ezlan.net/Installing#verify
If the above two Steps indicates that every thing looks good but
functionally it does not work.
Step Three. Check (and repair if necessary) the Socket Layers, Winsock, and
or refresh the TCP/IP Stack. http://www.ezlan.net/clean#refreshnet
If need to Reinstall; Log to this page it have a lot of links to
instructions for Windows Network Installation -

Folks, thanks for the suggestions. Will take a look when I get home
tonight.

may be u didn't set your dns? o

That was it! I was hoping it would use the ISP's DNS automatically, but
looks as though I had to give it the IP address. This means it now
works with an assigned IP. The "get address from DHCP server" route
isn't wokring, but at least I can now use the damned thing.

The two parts go hand in hand. If you "get address from DHCP server" it
will set up DNS as well. Otherwise, you need to set both the IP _and_ the
DNS addresses.

Yeah, XP will allow you to set static DNS with dynamic IP, but not the
other way around. Dunno what the appropriate RFC allows.

Hi,

A quick test for your DNS resolution.

Go to Start------Run ----type in CMD and hit OK

Type in nslookup

then type in www.yahoo.com

This should return an IP address for yahoo.com

If you get a time out, then you know DNS is not working...if you get an
IP address for Yahoo.com then DNS is OK.

If your DNS is not working, you need to ensure that you are using the
DNS servers from your ISP.....if you have a Broadband Router that is
assigning you IP Addreess, then the DNS server is the IP address of the
router.........if you have a broadband connection with a Static
Address, then the ISP needs to provide you with the DNS servers.

Hope this helped.
