Move router far from hifi components?


I just finished reading Hans Beekhuyzen's Kindle book on file based audio. This is what he said about where your router should go.


"Like cell phones, Wi-Fi uses radio frequencies that might cause interference in your stereo. Try to keep the Wi-Fi access point as far as possible from the hifiequipment and always use well shielded audio, power and network cables on your hifi. If Wi-Fi is your only choice, you’d rather hope you’re in an area that has little Wi-Fi traffic."

i don't think I have heard about this before and was wondering if this really makes a difference. I'm tempted to move my router and modem to another room to test but wanted to poll everyone to see if they have done this.

I realize this is a conversation from a couple if years ago, however, I just read it for the first time recently and decided to see if some if the advice contained within would help my system and I can say that it most certainly did. 

My WiFi modem/router is still close to my system rack, but I moved its power cord and also a couple of other various switching power supplies for the cooling fan, Roku and Aptx Bluetooth receiver I use when I am looking for something new to add to my Tidal playlist to a separate power conditioner I had  and plugged it into a separate outlet and I am very, very pleased with the results. 

I may try an isolation transformer later but I am really enjoying this essentially free improvement.
