Question about Cisco Unified IP Phone 9971-Charcoal Standard Handset w/ Cam CP-9971-C-CAM-K9
I am trying to connect my Cisco 9971 wirelessly in my home. It works fine directly connected to my router. I unplug (sitting right next to router - so it isn't signal strength) and no connection. My router is WPA2 - phone doesn't have WPA2 listed, so I chose AKM. Any ideas?

Then you need power adapter for Cisco 7960 IP phone ( -40V DC).
Cisco phones work best with Cisco, and sometimes ONLY Cisco switches.
One question which voice gateway you will use for your 7960 VoIP phone calls to go through ?
(AT&T probably supports only their IP Phones with special and usually hidden settings from end user)

If you can plug the cable that you have ran into your router into your computer directly and it works, then you can plug the router back in. Then connect the computer to the router via cable and unplug the router for about 15 seconds and plug it back in. If you connect the computer by cable directly and it doesn't work, then try unplugging your router for about 15 seconds and then plugging it in. I have found many networking items that need to be reset whenever a network cable is plugged in when the device is powered on.

Frequent wireless disconnection can be caused by different factors such as:
b-Physical obstructions: Your router or wireless computers may be losing connectivity because of physical obstacles such as walls and floors. Try to move the equipment to different locations to find a better link.
Having default wireless settings on the Linksys router may cause conflict with other Linksys routers within your network range. We suggest changing the SSID (network name) and the Wireless Channel of your router. Also, if it is possible, enable the Wireless Security of your router.
1)To change the router's SSID or the wireless network's name, click here.
2)To change the router's channel, click here.
3)To enable the wireless security on the router, click here.
NOTE: If the wireless connection remains unstable after performing the steps above, it could mean that your firmware is corrupted. For instructions to reload or upgrade firmware, click here.
I think is better to configure your router again, so you can set the router to keep alive every time.

Connecting a hub or switch to the "PC" port on the back of the phone is not a recommended best practice by Cisco as the IP phone does not support spanning tree protocol.

Tips for a great answer:
Wireless networks have become an increasingly popular way to access the Internet. Connecting to a wireless network allows you to browse the Internet without having to physically connect any cords to your computer.
Troubleshooting wireless connectivity can sometimes be confusing, because even if a wireless network is not able to bring you to any web pages, often your computer's wireless card will still connect to the wireless network that is being broadcast.
In other words, a wireless network will read "connected" even if it is not connected to the Internet.
Connect to a different wireless network. If there is an alternate wireless network within range of your computer that you legally are able to use (a free public Wi-Fi rather than your neighbor's wireless network, for instance), try connecting to it and browsing the Internet.
If the same issue occurs on the alternate wireless network, you may have an issue with your computer's wireless card or with your Internet browser.
If you are able to connect to the alternate network but still not able to connect to your own, the problem is most likely localized to the wireless network you use at home.
Reset all devices.
The great majority of Internet connection issues can be resolved by a simple reset of all the devices in your home network.
Locate the power cords of both your modem and your wireless router and unplug them (if you use a modem/router combination, simply unplug its power cord) for a full 30 seconds.
Plug them back in and restart your computer.
Try to connect to the Internet using your wireless network after your computer has booted back up.
If the connection still fails, some further troubleshooting is required.
Bypass your wireless router.
If your computer's wireless card is connecting to your wireless network of choice yet you are still not able to access any websites, there may be a connection issue on either your modem or router.
The easiest way to locate the problem is to temporarily eliminate the router from the network. Locate the Ethernet cable that connects your modem to your router and unplug it from the router.
Plug the cable directly into one of the Ethernet ports on your computer and reset the modem in the manner described above.
Now try your Internet connection again. If there is still no Internet access, the problem is most likely with your modem or your computer; contact the technical support department of your Internet service provider (ISP) for further assistance.
If the modem goes online directly connected, your router is causing the problem and may need to be reconfigured. Contact the router manufacturer for further assistance.
Hope this helps
