Had my usual issues last night, and hooked up the lengthy run of CAT5 and they immediately disappeared, probably to no one's surprise.
Now I have reliable audio, but the cable running through the house has disqualified me from appearing in Better Homes & Gardens magazine.
Next to try the other app suggestion from Huge, and send an email to Naim tech support...as well as start checking on the digital cable problem with the CD/DVD.
Unfortunately this strongly suggests that either your WiFi signal isn't strong enough or it isn't consistent enough at the location of your 272. If this is the case, using a different app won't help at all.
However there are still possibilities...
If you really do need to continue using wireless...
The simplest answer is to put a WiFi signal strength meter on you phone, then move your router around (within your acceptable limits) to maximise the signal strength at the location of your 272 however this may not be enough)
The best answer is to use a separate dedicated WAP (Wireless Access Point), rather than the one built into your router, connect it to your router (turn off the router's own WAP) and move this around to get the best signal strength)
Another possibility is to use a WAP in 'Bridge' mode - i.e. it acts as a separate wireless receiver which can then be connected to the 272 via an Ethernet cable. This could then be positioned somewhere closer to the 272 (where an Ethernet wire is OK), but where the signal from your main WAP (be that your router or a dedicated WAP) creates a stronger signal). This can also be combined with the dedicated WAP.
Lastly, and most disruptive, but still the best signal performance is to use a hardware Ethernet connection
You might consider using a fibre channel Ethernet and FMC, as optical fibres can be thinner and easier to hide than an Ethernet cable.
However, cable or fibre, you'll need to route it around door architraves, along skirting boards and through holes in walls / floors / ceilings etc., routing it where it can't be seen, but always paying attention to the minimum bend radius. (Consider cutting a thin channel into the corners of door architraves and skirting boards to 'round off the angle at the corners.)
