Move router far from hifi components?

There are a lot of great LPS available today I just chose the W4S for their versatility , the ability to hook up 4 different units instead of using 4 different wall warts or 4 different LPS, Currently the one W4S comes in handy powering my FMC, Aqvox switch and Optical TV line. The 2nd W4S and mentioned previously handles the router. I have found its very important and effects the SQ having high quality Ethernet cables vs the standard cables supplied from the Manufacturer like the basic PC from manufacturers are cheap and effect the SQ of the overall system. Mike Lavigne once stated, once you reach a certain level in a high end system the improvements are small but so important to the overall SQ. Boy is that the truth. Every little step regardless of cable, PS, isolation, room acoustics ,component makes an improvement. My system is Ethernet based and high quality Ethernet cables have definitely made an improvement .
I would very much like to get my hands on a Paul Haynes PS one day as Im sure they well further improve upon the SQ in any high end system.

In regards to the router being in a separate room my access point ( router are in the same room just 10 meters from my system and on a different power line, I have an isolation transformer running my system with digital and analog on different dedicated lines. 

I have found from reading about this on CA that running Ethernet with optical ( Isolated lines ) have made a huge impact on SQ and highly recommend it with anyone using an ethernet based system.

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.

My cable internet box, and WiFi router are behind the plasma TV.
Right above the power conditioner for my stereo. But I do keep them and the power supply for the laptop and powered recliner on another cheaper conditioner. Having used a noise sniffer to look for AC grunge. I can say neither are adding anything bad to the lines. (Unlike my Cd five disc changers!)           
Your digital gear is adding more garbage to the stereo than anything coming for the WiFi router. Even a lighting dimmer on another circuit adds more! to the lines or the equipment.Using a small isolation transformer for the digital gear AC line is a good idea.Plus realize.. check HOW MANY WiFi signals you can find? I can find over fifty in the air in my apartment. Some are very strong. directly above or below.. then next door and to each side...
