I immediately gave me after receiving it, the TL-WA850RE integrate into my network to have Wi-Fi throughout the house. Nope - after 3 hours experiment (both via WLAN, and LAN) I have unnerved abandoned. As a nice side effect to reinstall my network connections on the computer used for configuration is now required. As a 2nd computer on the same router still comes into power, I fear that it related to the TP-Link. As fast as I've claimed definitely not returning. For me, this device "scrap" - but as I seem, despite the many positive reviews, unfortunately, to be an isolated case.
