So I bought the RE505X, because the the Wi-Fi wasn't strong enough to let me play online videogames on my PS4. Ever since I bought the extender, I've had some major problems with it. The device isn't very reliable; normally the download speed is around 90 mbps and send speed 7 mbps, but sometimes they just drop to miserable speeds or the extender straight up stops working. Usually, after an hour of reboots and quick setups, it continues working. FYI, the extender is about 7 m from the modemn and behind two thin walls. I've had it stop working 3 times in 2 weeks, two of these occurences also leaving my PS4 in a state where it can't connect to any Wi-Fis or eithernet connections for hours. Also, when the extender's connection quality light burns red, everything works. When blue, the thing I just explained happens. I am extremely dissappointed with the product, and don't know, if my device is broken, just bad quality or am I missing something. Has anyone else had any similar experiences and what should I do?
