Hi Everyone,

             I wish to help a friend to get onto the internet wlrelessly through their HP Pavilion Entertainment dv6 Entertainment PC.  While the wireless on this laptop does detect available wireless networks and even connects to the desired one,  it still will not permit internet connectivity.  Through some technical investigation of this matter, I have found the following which might be of troubleshooting interest:

              First, the IP information of the wireless.  The IPv4 address of the wireless is 169.254.64.251, Subnet Mask: 255.255.0.0., and the Default Gateway does not have any value.  Of course, this IP information is not correct or what it should be.  What is really puzzling is the fact that the wireless "does" connect to the SSID or wireless name with excellent signal strength, yet, there is no IP information for the wireless router.  How is that possible?  That does not really make sense to me.

             Secondly, I did notice this laptop does have an HP Wireless Assistant which when opened only gives the options to disable/enable the wireless.  Now, this also raises a question with me.  Speaking hypothetically of course, could the HP Wireless Assistant somehow be conflicting with the integrated Wireless Zero Configuration within Windows Vista?  

             With regards to troubleshooting, I have tried the following without success to resolving this issue.  First, I carried out ipconfig /release and ipconfig /renew within c:\ prompt in administrator mode.  Secondlly, I carried out the following commands under the assumption it could be a corrupted winsock:  netsh winsock reset catalog and then enter,  netsh int ipv4 reset "c:\reset.log  and enter., netsh int ipv6  "c:\reset.log and enter.  I also checked the TCP/IP stack and noted it is set on Obtain IP address automatically and Automatic on the DNS portion as well.  I also turned off IPv6, but, it did not take care of this either.  So, I went back and turned that back on or enabled it for Tx and Rx transmission, whatever that means..lol

               Well, that is everything in a nutshell.  To be honest, I am very puzzled on this one.  If someone could get back with me with regards to other options available, it will be greatly appreciated.  Many thanks in advance for any attention given to this question.

                Thank you.

                 George

"First, the IP information of the wireless.  The IPv4 address of the wireless is 169.254.64.251, Subnet Mask: 255.255.0.0., and the Default Gateway does not have any value.  "

The "address" is an address that your wireless card in the HP is assigned (by itself) when it is unable to obtain an IP address from the router.

The problem may be that the router's DHCP server is not turned on; that the router is filtering MAC addresses, and does not recognize the MAC address of your HP, etc.

Have you tried connecting to any other wireless routers?  Perhaps one that is known to have its DHCP server turned on, and otherwise is willing to connect to whatever tries to connect to it?

Alternatively, have you tried to connect other machines to this particular router (machines to which it has not been previously exposed) to see if it will allow such connections?

And YES, the HP wireless assistant absolutely could be conflicting with Vista's built in wireless configuration.  One or the other of them should be turned off.

hello...try double-checking the password for that wireless network you're connecting to. There are times when you write the worng password that you are able to connect but since the password is worong you don't get an IP. For troubleshooting purposes, try turning off temporarily the security for your wireless network.

Hi Everyone,

             Thanks for the prompt replies.  The issue is not with the router because I have other computers, both wired and wireless which connect from it.  And, my friend did mention the same issue at their home using a router different from my own.  The router I am trying to connect too here at the house is unsecured, thus, not requiring a password.  

            At this point, I will go ahead and turn off the wireless within the HP software and see if that helps.  In the meantime, if anything else should come to mind, please feel free to post and I will try out any other ideas.

            Thank you

Note that if you have Vista there is no Windows Zero Configuration. Try uninstalling all the wireless software from HP and updating your wireless card driver.

Hi Everyone Again,

          While I know how to enable/disable wireless within the HP software, how may I do it within Windows Vista using the Wireless Zero Configuration?

           Thank you

Hi

            Since there is not any Wireless Zero Configuration within Vista, what built-in or integrated utility does it use to manager wireless connectivity?

             Thank you

Hi Everyone,

          I just noticed on the screen of this laptop a popup with the title of Enterasys NAC Assessment Agent which makes me suspicious.  Within this box, the following message appears:  The Agent has not connected to the server for 30 days.  If the agent is no longer required for network connectivity, then, it can be uinstalled.  If I am understanding this message, it is almost like this 3rd party program, Enterasys NAC Assessment is trying to manage wireless connectivity as well.  If that is indeed the case, should I uninstall this program?

          Thank you

Hi

          Ok.. here is where I am at with everything.  First, I did uninstall the HP Wireless Assistant and  Enterasys NAC Assessment Agent, then, attempted up update the wireless adapter within Device Manager by right click and selecting Update Driver and choosing let Windows Search Online for the most updated drivers and software for the wireless card.  After Windows got through doing its search, I got a message indicating the latest driver software is already installed for the wireless card.  Unfortunately, the uninstallation of those programs did not solve the problem.  In fact, I can not even connect to my wireless.  

            Now, let me take a moment and shift to something which might prove as a clue to resolving this problem.  When I selected the option to Diagnoise Problem when it was unable to connect to my wireless, I got the following message within a box with the title of Windows Network Diagnoistics: Windows tried a repair but a problem still exist.  This computer is set to manually connect to CCHS-WAP4.  To automatically conect to a network, change the network settings.  And, I have an option to view available wireless networks and connect manually to CCHS-WAP4.  But, this is not the name of my wireless, so, I am not sure at all where this is really coming from.

            Any further help here will be appreciated and needed.  

            Thank you

Hi

        Ok.. I deleted the wireless name CCHS-WAP4, but, I still do not have any internet connectivity.  Also, I still do not have an IP address for the wireless router either, yet, it says connected to unidentified network (name of SSID) which is correct.  While I know the SSID is the name of the wireless connection,  it is also the name of the router given when I logged in and configured it some time back.  None of this makes sense to me.  It seems that if it is connected to the SSID or name of the wireless or router, then, it would make logical sense there should be an IP address given for the router.  Otherwise, how could it connect to the SSID or wireless name managed by the router?  See what I am getting at?  

          Well, it is very late and I should have been in bed a long time ago.  I am  calling it a night for now.  If other ideas come to mind, please post them and I will give them a try tomorrow.

          In closing, thank you for trying to help me here.  Good night : - )

Hi Everyone,

           Thanks so much for the insightful and thought-provoking suggestions given within this post.  To be honest, I did learn a great deal from this experience.  The feedback given certaily allowed me to make sense of various key areas to address when attempting to troubleshooting any wireless connectivity issue.  Now, lets move on to what I did to resolve this issue.  

              First, I opened IE, went to Tools, Internet Options, Advanced, and clicked Reset to return the browser back to its default setting while still retaining my favorites along with cookies which store important log in information.  Secondly, I ran a utility called WinSock Fix.  After doing these things, I attempted to reconnect to my wireless and was able to do so.  Then, I ran an IP config test and did notice correct IP information displayed this time for both, the wireless and the router.  192.168.xx.x.
Furthermore, I was able to ping to the router and to a randomly selected website address, like google.com without an dropped data packets.  Since I had connection to the router and connection to the internet confirmed, I immediately opened my browser.  Unfortunately, the pages were loading very slowly or not at all.  So, I knew then I was not completely out of the woods yet.  To correct the very slow loading of the web pages, I logged into my router and changed the wireless channel from 6 to 11, and it solved the problem.  The pages began to load fast then.  Apparently there was some interference going on from a nearby wireless and changing the channel corrected this issue.

               In closing, this problem is now solved.  Many thanks once again for the insightful feedback given to this post.
