Weird WiFi problem with an HP laptop

My friend has an older HP Pavilion DV6-1253cl and it has Windows 7 on it and it will connect to the internet only through a wired connection. He cannot not connect to the internet at all through WiFi
I have tried using the internal card and several external USB adapters (One being High Power) It will actually connect to the router/access point but it will just have no internet access
I have tried ipconfig /release and ipconfig /renew and that did not do anything. I am stumped at what the problem is

I can connect to the same network wirelessly in the same room and I get internet access. This problem happens with every access point connection (except wired) so it is not isolated to a single router/access point

So I am asking what can the problem be?

Thanks

Strange, but I had the same problem with a laptop I borrowed to my grandmother two days ago in a resting home. Got an IP address from their router, but no ping and no network access whatsoever. Tried rebooting and whatnot, always got an IP address and default gateway, but no internet or ping availability. Thought it might be the location so tried moving for a stronger signal, but still nothing. Haven't rung her up to see if it fixed itself but that one had me stumped. So if anyone knows how to troubleshoot this one I'm also listening.

Thing the computer is an HP also, an older one. Weird thing is, here at home it works just fine, never had any problems with it whatsoever.

I already tried a live Linux (Linux Mint) from a USB drive and I could not get the WiFi to work. Would it work in Ubuntu?
Anyway when I get a chance I will do the ipconfig /all thing and post the results. Next time I see my friend I will do that

Maybe this can Help.

Assuming that the Router's Wireless is configured correctly that there is a strong signal and the Wireless card on the Computer is physically on.

Go over these steps and tell us where the breaking point is.

Check the Device Manager for valid Wireless card entry.

If there is No valid entry, delete any Bogus Entry, and re-install the Wireless card's Drivers.

Check the Network connections to make sure that you have a Wireless Network Connection Icon/Entry, and that the Properties of the Icon (right click on the Icon) are correctly configured with TCP/IPv4 protocol in the Network Connections Properties.

------------------
Many Wireless cards' drivers also install the vendor's Wireless utility.
Make sure that if there is a vendor's Wireless Utility is Not Running together with the Windows native Wireless utility (WLAN Service) .
----------------
Make sure that No Firewall is preventing/blocking the Wireless components to get to the Network.
Some 3rd party Software Firewalls/AV/Security suit,s keep blocking aspects of Local Traffic even it they are turned Off (disabled).
If possible configure the Firewall /Security suit correctly, otherwise totally uninstall it, and get rid of its residual processes to allow clean flow of local network traffic.
If the 3rd party software is uninstalled or disables, make sure that Windows native Firewall is On .
3rd party Network mangers like Bonjour, and NetMagic can block local traffic too.

---------------------------
Working TCP/IP stack should look this way.
Right click on the Wire card Network Connection, choose Status, Details, and see if it got an IP and the rest of the settings.

Description is the card manufacturing data.
Physical address is the card's MAC number.
The xx should be a number from 0 to 255 (all xx same number).
yy should be from 0 to 255
zz should be from 0 to 255 (all zz the same number.
The lease date should be valid to the current time.

*Note 1. IP that starts with 169.xxx.xxx.xxx is not valid functional IP.


*Note 2. There might be an IPv6 entries too. However, they are not functional for Internet traffic or LAN. They are needed for Win 7 special HomeGroup configuration. ---------------------------------------------------
A message in the Wireless little Window that says Connected does not means that your are really have a valid functional connection.
If everything above is OK you have to be able to connect to the Router.

Connecting to the Router means that you can enter the Router's core IP into an address bar of a browse, be able to connect, see, and configure the Router's menus.


If it does not connecting to the Router, log from any computer that can connect to Wireless Router with a Wire, disable the Wireless Security, make sure that the Wireless broadcast SSID is On, and try to connect with No Wireless security.

Enable the Wireless security after you mange to establish a functional connection.
