Router Problem, could a wifi printer cause it?

[newmember27]

Hello,

Just installed a wifi printer and installed the drives and so on. The printer worked. Right afterwards the xfinty comcast router was not connecting with our wifi devices. Connecting with a lan cable is fine.

Any idea what the problem is?

FYI, I don't know anything about routers...
