NetworkManager Applet 0.7.0 always drops connection after ~30 seconds

Every time I boot my computer, I pick my wireless network (NETGEAR) from a list and it connects. However, the NetworkManager Applet always tells me the signal is lost after about 30 seconds. I know the router is working fine and I did not have this problem until I upgraded to 8.10 Intreped Ibex. I will be happy to provide anymore information that may help to solve this problem. The command output below has been produced after the wireless connection has been fixed, or reselected.
Should I file a bug?

the lspci command output reads:
