Wireless router "contamination" of sound?

A follow-up to my previous post: I would not rule out the possibility that RFI (radio frequency interference) or digital noise from the router, unrelated to (and at much lower frequencies than) the wifi signal it broadcasts, could couple into the audio system and have audible effects. The likelihood of that occurring would increase, of course, with decreasing separation between the system and the router.

The same effect is perhaps just as likely to occur with a router that does not include a wireless function, depending on the specific design and on the specific audio system and setup.

I would not place my audio gear physically close to any typical household computer or router due to potential for RFI type digital noise as Al alluded to. I tend to avoid wired connections as well just as a precaution.

Otherwise Wifi and other radio signals in the air should have no effect on the sound of most audio gear under normal circumstances. The proof would always be in the pudding though via testing with and without presence of suspect offending devices.

A Wifi network data connection from computer server to audio gear is an excellent solution for best isolating potentially noisy digital computers from audio gear that I strongly recommend when needed.

I had the same thoughts so tried switching off the household wifi while listening. I could not hear any change. My system has become more resolving since then so I might try it again sometime. Agree with the comments on isolating the system from some noise via wifi vs a wired connection, and I also think that an optical connection can potentially provide better isolation from other components than coax.
