I have an issue with RT-AC87U, which has annoyed me for some time. I have the same issue with ASUS original and Merlin fw.
My problem is the instability of the DLNA on the 5GHz band. It works perfectly over 2.4GHz. On 5GHz it works occasionally. The media server and media renderer disappear and reappear randomly from my control point running on an iPad connected via the 5 GHz band while on the 2.4 Ghz band it work like a charm. I have tested with different devices and the issue is repeatable for all of them. Typically media server and renderer can disappear for several hours and reappear and stays visible for a few hours.
Is there anyone that has any ideas?
