router keeps getting disconnected
Hi,
I have a wifi router HUAWEI Echolife HG814V5 . I was able to configure the extender WA850RE V2 with it. However, the internet works successfully for few minutes and after that , the extender shows 'can not connect to network'. When I restart the extender , it works for few minutes and again same problem. I have done the firmware upgrade as well as turned off the auto DHCP. Also, all the LED signals include RE are on the extender.
What is the problem here? How is it that the externderis able to connect for few minutes on internet when it starts and again disconnects?
Please advice
