Question about Dell Inspiron 9400 Notebook
If you add an extension card then the onboard card would automatically stops working and the computer will give priority to the card. However, you have to make sure that the CARD is compatible with your motherboard. There are times when extension cards have conflicts with other hardware parts.
What's the build of your computer? What the specs of the card?
Please provide me with more information when you get back to me.

Go to "Device Manager" and look if any yellow or red alerts are being displayed next to any devices. To access the "Device Manager" go to the 'Control Panel", "Administrative Tools", "Computer Management" and select "Device Manager" located in the left side column.
If there is an alert, double click on that device to determine the problem, i.e.… device not configured, cannot start this device, etc…

depending on your ISP, this may be a common problem. I have Verizon DSL and wireless is included on the modem. I recently expirenced a similar problem and i hardwired my laptop to my modem (you can do this with your router as well) via ethernet cable and this worked for me. once you get internet this way, unplug the cable and you should be connected wirelessly

If you can here sound in headphones, but not through the speakers, most likely the phone jack switch is bad. The whole jack needs replacement.
Also, in some cases, it could be more then that, like Audio CODEC chip on motherboard is bad, but lets assume the best.
