This happens on my laptop, phone, and gaming consoles. I've called Comcast multiple times for router resets, diagnostic checks, and even had a tech come out to replace the lines. Both the original Comcast gateway and my new Netgear AC1750 DOCSIS 3.0 gateway display this problem.
would indicate some kind of problem common to all devices
how are the devices connected - wireless, cable or a mixture of both
if they are all wireless -can you try connecting with a cable to say the laptop and see if that disconnects on a cable connection also - that would eliminate any wireless issues
assuming they are all wireless - lets have a look at Xirrus and see if it maybe interference or signal problem

post a screen shot of the program running.
if there are a lot of networks showing can you click on
"networks" top lefthand area - so we can see all the network information.
post which SSID name is yours, its located in the list, under network "Adapter Name" (1st column)
Note:
For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about
-70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be
green".
note: the signal level is a negative number, so for example -88 is worst and -40 is better
