Hello, I have a setup where 1 NJ is connected via Ethernet cables to 5 NBs. It is working fine. However, the client has requested the devices to be connected via WiFi instead of cable. I bought 5 TP-Link WiFi Extender and disabled the extender function, so it just function as a receiver. But I am getting intermittent problem. There are some buttons in the NB that are link to the addresses in NJ, and these buttons will flicker at times at random. I tested this same setup back in my office too, but I get the same results. The traffic for the router is definitely not a problem because I am the only one using it. Any idea how to solve this flickering issues? Thanks a million!
