I only use for the sole purpose of dlna to watch some movies on my tv, no other data is accessible through it, the last time I upgraded the fw I had some issues with this feat.
I'm still in 384 since last year, upgrading f/w for ASUS is like playing Russian Roulette. Since my router is fine till gonna wait till the end of 2021 to see if someone else Router is not exploding or something.
Same issue here, we pay top dollar believing we are acquiring a final product, but in the end we spend the life of the product trying to get it to work, like some alpha tester.
I'm using AC86 and can't use this software, tried to install using the link in the FW and it got stuck, then when i plug in my HDD the option to install disappers, and the windows app won't connect.
