Routers are the modern equivalent of TV antennas -- essential eyesores that don't really fit in with the rest of your home decor. Here's a decorative tip from IKEA Hackers that will keep your router hidden from view while also extending your Wi-Fi coverage.
To make a discreet router placement, all you need is an IKEA Ribba picture frame, which retail for $5.99. This has a deep frame which should fit most routers. You'll need to make some openings in the back for ventilation and to allow the cables to come through but otherwise no DIY work is required. For a cleaner look, you can also add plastic ducts/trunking to hide any protruding cables.
As an added bonus, you should also be able to get better Wi-Fi coverage by placing the frame closer to the centre of your home, as opposed to being tucked away in a corner. The only downside to this solution is that you'll need to pull the frame off the wall and fiddle with the back whenever you want to switch it off.
