laptop sees network can not connect
Hello and thanks for being here!!

I have a desktop computer which has a Realtek wireless access point. My Dell lap top will not connect to it!! It sees the AP but it can not connect. When I IPCONFIG and ping it the lap top comes back with an autoconfiguration IP Address of 169.254.206.64.

I have tried it with an unsecured, unfirewalled configuration and visa versa. I have uninstalled and reinstalled the wireless router. No luck.

Any ideas at all?

Thanks

Jim

Make sure the laptop radio is on. There might be a key, such as FN+F2 or a slid switch to turn the wireless radio on. Look for antenna symbol on the dey board or on the laptop.

Then, for both computer:

Start, Run, CMD to open a command prompt:

Type the following command:

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here {credit johnw}

TCP/IP stack repair options for use with Windows XP with SP2.

For these commands, Start, Run, CMD to open a command prompt.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

Reboot the machine.

Also, please explain how your system is setup. Do you have DSL? When you say access point is connected to desktop what do you mean?

Explain what connects to what starting from the modem

Does the Realtek wireless access point have a model designation? And, how have you configured it? There doesn't seem to be any connection to it in your desktop's ipconfig???

Or are you talking about the Realtek RTL8187 Wireless adapter shown in your ipconfig? If so, then you have to tell your laptop's Intel(R) PRO/Wireless 3945ABG that your wireless network is ad-hoc; have you done so?
