Connect to desktop - Motorola MC9190-GST

Most desktops need to be connected with a wire to your network because most desktop computers do not come with a wireless NIC (network interface card). If you are not sure if yours has one you can get your service tag off of your computer and type it in the Dell website (link below) under drivers and downloads and look at the original configuration for your system. If you have a Wireless NIC card in your desktop it should connect just like your laptop computers did. If not you may have a defective wireless card.

Dell Website

Either the "data" cable between your screen and your desktop is defective, or that cable is not connected to your screen, or that cable is not connected to your desktop, or the video-card inside the computer is defective.

Check the connections.

Temporarily connect the screen to a different laptop/desktop computer, to see if the screen still works.

Temporarily connect a different screen to your desktop, to see if your desktop's video-adapter is working.

Download and install the latest Handheld Software for your model then open Desktop Manager and run the application loader once the USB cable is connected to the device. 8220 Software located here https://www.blackberry.com/Downloads/contactFormPreload.do?code=1905AEDAB9BF2477EDC068A355BBA31A&dl=702BB8A8D212AB863750ABA38D5103B0

Just fill out the form and the download is free.

you can buy a cheap USB wifi adapter and connect the desktop wirelessly just like your laptop, this should do the trick.
or you can buy an access point to extend the range of the wireless network, you should not be moving the router itself this way.

I have the same problem. Startign this morning, when I connect modem directly to desktop, it works. But when I connect modem to this router and then connect to desktop, nothings works.

again - if connect modem back to desktop directly, then it works!.

what is the issue.....? not able to figure it out.

I did reset, change router IP etc etc everything nothing resolves the core issue!

connection is to the router not the desktop pc
Ignore the desktop pc
check the wireless security settings in the unnamed router and make certain that the non-connecting laptop has the same settings.

It sounds like you had a pre-release version of RDC 6.1 installed which you should have uninstalled before installing SP3.

Check this out - under "Remote Desktop Connection" you might find the solution you're looking for.

Hope this helps! : )

Have you checked to make sure the laptop wireless NIC isn't acting as an AP by mistake? That could explain both desktop and laptop connectivity issues. Just a thought.

Sounds like you are setup to use Internet Connection Sharing. don't do this. Have each computer connect to the internet via the router. If the router is wireless connect all computers wirelessly to the router that are wireless capable and any computers that are not wireless capable, connect them to the router via a cat5 cable to the cat5 ports on the router. This will solve your problem. BPCS
