I bought the TP-Link Archer C2 to equip my cable Germany Internet connection with WLAN and etc. to hang some devices like a NAS, a Raspberry Pi into the net. The technical data read well and the price was right, so I slammed. Unfortunately, I was not at all convinced of the C2. I've gotten the second copy in use and also this one I will return again to Amazon. The reasons are, firstly, that the Wi-Fi, especially in the 5 GHz range, extremely unstable and slow is often simply want off the connection, even if you only 2m away sits. Secondly, breaks the performance in Lan after approximately 12 hours of operation, then I can on my NAS only data at around 10 MB / s copy, with my gigabit switch go between 50 and 60MB / s through cable. You then reboot the router, to get back to the old performance, but I will not start my router 2 times to start every day. Perhaps there will soon be a new firmware out which will fix the errors listed, at the current time the product is anything but mature.
