I have an old DELL Dimension 8400 desktop with a DELL 1450 Wireless USB Adapter. It was working fine with my Linksys wireless router. I had to replace my wireless router. I now have a D-Link 825 Dual band wireless router that I installed without any problems. Other PC's I have are NOT having any trouble with the new router. The 8400 does not find any networks in range even though the router is only 5 feet away. Where is the wireless switch on the 8400 located at?
There isn't one.
Only laptops with the miniPCI wireless adapter can make use of the F2 key.

If there isn't one then why doesn't the wireless network show up when I display available networks? The other Laptops I have pickup the new network without any problems.
I see that the Dimension 8400 uses a USB Adapter. Is the Dell Wireless 1450 (802.11a/b/g) USB2.0 Adapter installed?

In order for the USB Wireless Adapter to work, I would suggest this.
Update the firmware in the D-Link wireless router
Make sure to change the SSID to something you didn't use before (This will make connecting easier)
Broadcast your SSID
Use WPA-PSK (TKIP) Security (Personal) (The USB Adapter likes this type of security)
Use channels 1, 6 or 11 (The USB adapters work best on these channels) I use channel 11
Use mixed mode.
Make sure your password is at least 12 digits long.
Save everything and exit. Turn off your ISP Modem/router and your D-Link wireless router. Wait 30 seconds. Now turn on the ISP Modem/routeer first. Wait 30 seconds, then turn on the D-Link wireless router.
Restart your computer.
Now try to connect to your new network.
What is a Dell Service Tag and how do I locate it?
