This morning I updated the firmware to version 7.6.3. After updating I lost my internet connection and my wireless network. Any ideas on how to fix?

Hi, instead of resetting the base, whichever it is, I would downgrade the firmware. In this case from 7.6.3 to the previous 7.6.1. You need to hover the cursor over the firmware version number of the base in disk utility.
If you have lost connections, your base might be invisible in the disk utility. Simply connect the MBP and the base station, then the base becomes visible again. Now do the firmware downgrade. This way worked fine for me.
Now, we are to wait what apple does about the unfixed fix, or whatever you may call it.
Hope I could solve your problem. Cheers.
Sorry connecting was meant with an Ethernet cable.
I have Airport Express and had similar problems, so I downloaded and reinstalled 7.6.1 (never got 7.6.2).
The following includes instructions on how to install older versions of Airport firmware:

Hope that helps.
I agree with all posters suggesting to downgrade. 7.6.1 just works better. All you need to do it hold option with your mouse over the firmware version in Airport Utility and then select a different version.
Firmware update to 7.6.3
