Running Vista. My laptop won't conenct via wireless, but other laptops i add can connect via wireless to motorolla SBG900, even though i have added my laptop's mac address for the dell wireless card.

This is worked for me on Vista:
1. Goto Network and Sharing Center.
2. Click on your Wireless Connection "View Status".
3. Click on Propertes.
4. Uncheck the option that says "Internet Protocol Version 6"

When I did this, my wireless began working again.

Yes you can use this device for that purpose.

In my case I had the SX515W configured via USB with other computer with Win XP, and later working by WiFi.
With may new laptop with Win 7, I have the error with the NetSetup installation CD.
First I checked that it was possible to print via USB with the laptop, and after I added by wifi using the "add new printer wizard" as explain Quagmire69 in the link attached.
Good luck

Reset your wireless card in your laptop.

Hi,

Please check the security feature which you have enabled on sgb900. I dont think that running vista or Xp will make any change.

Vista is tricky when adding networked printers.  
Add printer by using a local device, not a networked device.  Assume the printer is connected locally to the machine.

I suggest you network the printer and access it through the wireless access point.  

Also, I do not mean to insult your computer smarts, but if you do not have a driver installed, you will not be able to talk to the printer at all.

Is the problem connecting to the wireless or the internet?

When you look on the box that the router came in, you have to look to see what Operating Systems it is compatible with. In many cases, routers will not be compatible with vista. I have a Linksys WRT300N, and it works great with Vista.Hope this helps.

Hi!

Try these:

1. Go to CONTROL PANEL > MANAGE WIRELESS NETWORKS
2. Remove all the preferred networks
3. Restart your laptop
4. Reconnect to your network

Hope this helps!
