I use RT-AC88U as my main router and EA-AC87 as media bridge.
I recently updated my RT-AC88U to latest Firmware version 3.0.0.4.380.2345 but it has brought a new problem with my EA-AC87 using Firmware version 3.0.0.4.374.2849 in media bridge mode. Before it did not have any problems and media bridge mode stayed connected and all ports were able to get internet connection. But after i upgraded my RT-AC88U to latest Firmware version 3.0.0.4.380.2345, EA-AC87 stays connected in media bridge mode and can be found on network using device discovery software but after around 10-15 mins my connected devices to the ports of EA-AC87 all disconnect and have no internet access. EA-AC87 can still be seen as connected in bridge mode but all the LAN ports seem to have dropped my connection and no internet access until i reboot my EA-AC87 and then it will have internet again for 10-15 mins and then all the LAN ports will drop my internet connection again.
There has not been a firmware update for EA-AC87 for a while but i see this thread there is firmware 2851. Was thinking if anyone can upload this firmware for me to try and see if it will solve my problem as i do not want to revert back to previous firmware for RT-AC88U as it has solved some of my other problems i had previously.
