hi guys, i want to ask if there is someone had the same problem as i have.

my wifi connection is not reaching my room so i bought TL WA854RE as an extender for my connection

the connection is good to reach my room with a strong signal. the problem is my computer can't connect to the internet after successfully connected to the extender. it always get tentative ip address. even if it connected, after 5 minutes it gets tentative ip address again. and the PC is the only one facing this problem. other devices like laptop, and smartphones can connect effortlessly. 

i use TL-WN881ND as wifi adapter and TL-WA854RE as range extender and windows 10 Pro operating system

i tried so many ways to fix this problem such as :

• restarting the extender and the router
• rebooting the extender
• resetting pc network 
• using same SSID as the router
• turning off DHCP in extender
• getting the latest driver/firmware both on extender and wifi adapter
• even i reinstalling my windows

my question is what caused my pc cant connect to internet via range extender and how to fix this problem?

i am searching everywhere to solve this problem and getting desperate for a solution, so kindly pls anyone who knows can help me with my problem,

thank you
