I have installed a DLINK DI-634M wireless router.  Using cable provider as ISP.  The modem and router are hard-wired to one computer, which is accessing internet successfully.  I have installed a DLINK wireless adapter (DWL-G650) into a laptop computer (HP Pavilion ze4430us).  The card is installed successfully and I can see the network from the laptop.  I can also ping the router from the computer successfully.  I am unable, however, to access the internet through IE.  Also cannot ping any internet sites.  I have disabled the windows firewall and have no other firewall software running.  Operating system is XP Home Edition.

Thank you.

Will the hp laptop access the internet through IE on a wired connection?

Also, I want you to go to start<run<   type in              cmd              hit ok,  at the command prompt type    ipconfig /all     and hit enter, post the info displayed, ip address, etc.

A physical reset of the router may help, look for a small hole or button near the antenna, depress it for approximately 30 seconds with the tip of a pen if its a hole, when all the lights are done blinking, reenter a security password, and try it.


Also download netstumbler, http://www.netstumbler.com/downloads/     install and run it, make sure you're using a different channel than your neighbors.


Also, you may want to try uninstalling the wireless adapter along with the software, reboot, then install the software, turn off the laptop, plug in the card, start computer, then windows will detect the new hardware and install.


Check for malware; Download Ewido http://www.ewido.net/en/download/


Install and run the scan, let it delete all it finds.


Go to http://www.merijn.org/files/hijackthis.zip and download the file, run and save a log file.

How have you connected the router? Does it have a wan and some lan wired connections? If so, connect the wan port to the cable modem, the lan connector to the other wired PC's. Also turn the cable modem off, then on again. You should now be able to connect to the internet on all lan and wireless ports.

If you have a setup where there is another internal DHCP server, then turn the DHCP server of the wlan router off and don't use the wan port. That way all connected PC's will get the addresses from your preferred dhcp server. If your other PC is connected directly to the cablemodem, you might have a problem with the ISP, as they often allow only one connection at a time. If that is the case you will have to use the wlan router for the other connection as well.

I have one PC hard wired directly to the router, which is connected to a cable modem.  Comcast is ISP.  I have attempted to reboot the pcs and the router.  I have also checked for malware and removed all files it found and installed netstumbler (did not find any conflicting networks).  I also checked the ip connections from the working laptop and found a DNS suffix that I coded into the nonworking laptop setup.  None of this has worked.  

The laptop that is hard wired to the router is DHCP Enabled.  The nonworking laptop is not.

That looks good. Can you ping www.google.com and ping 644.233.183.99 and post the results here? Have tried a browser like firefox to browse the web?
