Auto DNS and IP

A friend is trying to set up a US Robotics WiFi/Router/Printer Server initially through the LAN. He has the published parameters in the correct boxes (in the set up program connecting to the US Robotics web pages).

However he cannot connect to the Internet and the hitch may be the auto DNS / auto IP settings have been carried over from his USB ADSL modem.

Would the use of ipconfig/release and then renew help solve the problem? Or can anyone suggest other routes to helping him connect.

Has he checked with his ISP if the MAC address for his previous modem, or PC used to connect previously, needs to be cloned for this new WiFi ADSL router?

I presume it is a new ADSL-modem & WiFi Router combined, which replaces the older USB ADSL modem?

Danoh - yes it is exactly that. His real problem is he's in Spain and talking to the local ADSL provider (Telefonica) isn't easy. Imagine you talking to BT about Broadband but in Spanish to see the difficulty.

Is it possible to change the MAC address of the new US Robotics kit to the old USB modem MAC address? I know you can do it for USB WiFi sticks but can you do it for other equipment?

Any help gratefully received!

I seem to recall reading of problems when trying to connect via a router if the previous USB ADSL setup hasn't been uninstalled. Try uninstalling all of the software relating to the USB modem.

Running IPCONFIG /ALL will show you whether or not the PC's network adapter has got an appropriate address, because it should be a LAN address rather than one allocated by the ISP.

Routers do normally have the facility to "clone" the MAC address of a network adapter, either automatically by reading the PC's network adapter or manually by typing in the address. This requirement was more usual with Cable broadband where the MAC address registered with the ISP was used for authentication, whereas ADSL ISPs authenticate with a Username & Password. It wouldn't do any harm to enter the USB modem's MAC address into the router's settings if you can find it.

mgmcc - thanks. I'll ask him to try removing the USB Modem software and changing the MAC address. Let's see what happens.

It seemed to be a combination of many factors including the MAC address and the old USB ADSL software. When a new laptop was LAN cabled it worked correctly, so the USB ADSL drivers etc were uninstalled on the old PC and it worked.

Many thanks everyone.
