Why does MacBook Loose Wi-Fi occasionally?

My wife's MacBook that was working fine in the same room on the Wi-Fi network from my Time Capsule now cuts out for a minute or two occasionally every day. I've had other glitches since installing OS 10.8.5 on both my iMac and MacBook and suspect this is another of them. I tried switching from the MacBook Network 5GHz to the MacBook Network 2.8 but it made no difference. Both are set on Automatic so it doesn't select a specific Wi-Fi channel if one of the neighbor's networks is interfering. Perhaps I can go in and change that; should I?

iMac (21.5-inch Late 2009), OS X Mountain Lion (10.8.3), Comcast broadband, TM

Change your router channel number. Most times this works & is all you have to do.

Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.

System Preferences>Network

Click the Assist Me button.

In the next window that pops up, click the Diagnostic button & do the necessary.

If using a Linksys router, contact LinkSys Customer Support and/or post in their forums.

Automatically is greyed out so I cannot change to a particular channel. Shouldn't it choose the most interference-free one? Haven't tried the unplugging for awhile so will try again. As I said, I have Apple Time Capsule for my router and it has worked much better than the Linksys I had before. Until now.

As recommended in my last respone, post in the Airport forums.
