My PC is Dell, 2GB RAM, Win Vista Ultimate. I have a router supplied by my internet-service provider. I added a wireless access point (D-Link). It worked well. Recently the router was changed. The connection is ok when the router is connected directly to the PC. When it is routed through the access point, connection was lost. After correcting the IP ad it works. But it is not working when the encryption is enabled.

My questions are:

On the D-Link (access point) adapter properties which IP ad should be written? When the D-Link default is entered it woul not work.

Should I enable/setup/delete the LAN (Intel) adapter? If enabled which IP ad?

Which will be the gateway?

I am not a computer professional, just a PC buff. Could you suggest "a simple, essential reading" on the topic for me?

Open a command window:
Start > Run > type in [u]cmd[/u] and click OK.

In the command prompt window type [u]ipconfig[/u] and press Enter. You will end up with something like this:

Do you mean a different router was installed or a change was implemented on the router.

Either one could have changed the default addressing scheme the router uses for the internal network.

e.g. Default network address changes from
192.168.0.1 255.255.255.0 to
192.168.1.1 255.255.255.0

I have noticed this seem to be the trend for new home router devices.

If the router has changed to the .2.1 range and the AP is still on .1.1 then the AP needs to be reconfigured
