Just a rant/update; ~6 months later.
I am still trying to use the DSL-AC88U-B as I used my DSL-N55U; as a small low-power “downloadstation/NAS” with transmission-daemon and nzbget to a small external harddrive.
It works, but only for a few hours to a week at most. At that point the DSL-AC88U-B gets stuck, no internet, does not accept new WiFi; I do not remember if it responds to ping at all, or if L2 switching works… most times the router restarts on its own, but a few times it stays unresponsive until I power cycle it.
I tried a “control-test”; not rooting it, for 5+ days and it did not get stuck so I concluded that something in my root process causes it. But I have not been able to isolate it. Also I am still uncertain about the “control-test” because sometimes, 2-3 times, it has run for 5-8 days while being rooted. I have never seen abnormal temps; ~50c / 70c / <50c, at least these are the temps when it is responding.
It got stuck in a slightly different way tonight, in a way I have only caught once before. I lost internet connection, router web interface said connection was still up, devices noir router could ping any internet IP. The router still responded to local requests and I was still conected via SSH, so I htop and saw this:
See attached screenshot.
Core 1 was at 100%, but I saw no command/process using any significant CPU time. However, all of those wl phy_tempsense commands look odd. After a couple of seconds, 2 minutes at most, core 2 was at 100% and it crashed; stopped responding and I had to physically power cycle it. That was when I took the screenshot.
Apart from the most recent firmware I have tried with 503 firmware too, but the results are the same.
I paid close to 500 EUR for this product, as well as days worth of tinkering to get it to work and it still does not live up to half of what it is supposed to. My patience is not an infinite resource and I am looking forward to ditching this for another brand that actually works AND supports VDSL2 bonding for less than half the price of the DSL-AC88U-B. Unfortunately I have not found a way to get root on that one yet, but soon I will not need it at all.
The DSL-AC88U is a mistake. The fact that Asus has not acknowledged the IPv6 issues for ½ a year is telling enough.
