Upgrade to RT-AC87U

Hi all,

After using a RT-N66U with Merlin's firmware for many years, I need to upgrade to 'AC'.

I was considering either the AC68U or AC87U as my next upgrade.

The AC87U is currently on offer and there are mixed reviews on it's performance. I have mainly seen two issues constantly pop-out; high temps and 5GHz WiFi problems.

Are these old issues and now resolved with firmware updates?

Also, will Merlin's new AM382 firmware be supported on this model?

Thanks in advance.
