but nothing so if anyone can help me i would really appreciate it.

 

I had neighbors with these problems. Simply disable your firewall settings and let me know if that helps.
Directions: Start>Connect to> show all connections>right click wireless connection>hit properties>the advanced tab up top> then the settings. Then click off. That is usally the problem. Let me know if the problem persists.
Also update the drivers and firmware for the card and router.

 

What kind of wireless card do you have? If it's an Intel card, go to their website and download the latest driver package for your card. I did it for my PRO2915 and I got a much better connection.

Also, what kind of encryption are you using?

 

I don't have a firewall or a router. My laptop is a Sony vaio S560P the ethernet card is build in. (none of does ideas worked thanks doe)

 

What laptop and card is it?

 

if you are running windows xp then you have a firewall and it is on by default.

how are you connecting to the internet? wireless? NIC? straight into the cable modem?

we need more info to be able to help you.

 

Yes the more info the better. There are hundreds of possible solutions and problems.

 

Joker,

From what you have indicated below:

1. Cable modem (not DSL)
2. No router/firewall, direct connect to modem
3. Works on desktop wired nic, but not on notebook wired nic
4. Limited or No Connectivity error

From what you've listed, it sounds like you're not getting an IP from your ISP. If you run IPCONFIG /ALL from the command prompt (Start -> Run -> CMD), you will probably have a 169.xxx.xxx.xxx based IP address for your built-in network card and DHCP Enabled should say Yes.

This might happen because your internet connection may be limited to a specific MAC address (each network card has a MAC address, like a serial#). If this MAC address doesn't match your desktop's MAC address, the connection will not happen. There's no easy way to modifiy a MAC address, so the only way to bypass may be to get a wireless router and clone your desktop's MAC address. This will report the desktops MAC address to your ISP and allow you to share the connection between your desktop & notebook simulateously.

Either that or your ISP requires a static IP to be setup. A specific IP/subnet may have been used for your desktop to connect to the ISP's network. If this is the case, you just need to modify your notebook's NIC to use the same IP address or same IP range as your desktops NIC.

To check if a static or dynamic IP is used, you can do the following:
1. Start -> Run -> CMD -> IPCONFIG /ALL
2. Should say if DHCP Enabled is on or off, if off Static IP is used

Or you can do the following:
1. Start -> Settings -> Control Panel -> Double click Network Connections -> Right Click Local Area Connection -> Properties -> Double Click Internet Protocol (TCP/IP)
2. If there are any #'s entered, it's static, if not, it's dynamic

If they're static, just put the exact same info into your notebooks TCP/IP settings and see if it works.

Good Luck!
