Slow connection with TL-WA860RE
Hello guys.
So some days ago I bought a TP-Link TL-WA860RE range extender in order to resolve the bad connections in dead wi-fi zones.
I have the router in my bedroom connected to my PC and then I have some equipment (PS4, laptop and smart tv) in the living room which are connected via Wi-Fi. The signal was not the best in this place so I bought the range extender to improve the signal.
I pressed the WPS button on the router and then on range extender and everything was correctly configured. The next step was move the extender to a place in the midle of my bedroom and the living room. With the app Tether I did a zone test and it says it is perfect.
So far so good until I start did some speed tests. My bandwidth is 120mbps. If I test near the main router with my cellphone I get the 120mbps which is perfect. If I test in the living room I only get in max 25-30mbps. And these speeds are a mess because I could already achieve this without the extender. I'm not expecting 120mbps of course but was expecting like 70mbps. Even if I move the extender even more close to the router there is no improvement at all. The router is working with 802.11n so I could get the max speed and it is on channel 11. About security is working WPA2 and with AES encription. The bandwidth of wi-fi channel is 20MHZ.
I don't know what is the problem and I'm creating this post hoping you can help me fix the problem.
Thanks for your attention.
Best regards and happy holidays!
