Why risk it? Use rasp pi and feel safe in the knowledge that you are in control.
TP Link has many advantages over the Pi:
- can restart your miners, Pi would need a script and relais
- less than half the price (15-25$ WR703N vs 30$ for bulk Pi)
- already with Case, has Wifi and comes with USB cable and Wallwart
- no SD card needed and commandline-tinkering for network setup
- smaller and you dont feel like wasting overkill features like with a Pi
but i wonder, why dont someone just build a LuCI GUI for cgminer and slap it on generic OpenWRT
