Complete POS, Ai Protection still reduces WAN speed to 1/4 on a PPPoE gigabit connection. Avoid at all costs. I really don't understand the reasons Asus keeps releasing these crappy firmware versions. Probably it is their way of saying: F U, guys, time to buy another router, we are killing your old model.

I was about to upgrade to Merlin, when this showed up in the router. I updated to this for now and it’s been running very well. I still want to try Merlin, but will run this for awhile and see how it goes.

 

[dieter]

Upgraded my AC1900P without problems. (The previous version also had no problems.)
AI Protection is NOT slowing down my WAN speed (900Mbps UP/DOWN).

However, my Logitech Harmony Hub shows up as a WIRED client, instead of 2.4G wifi.

If anyone finds out what the performance improvements are, please post it.

I guess the problem is with PPPoE gigabit connections. This is the third consecutive firmware that has serious PPPoE speed issues.

Reported it to ASUS?

 

[wouterv]

At least this fixed the Status Tab (showing CPU and RAM usage), and the new Ethernet Ports status overview.

I've been reporting these speed issues to Asus support since they were first introduced (firmware 7743). I tested every firmware they released since, sent them comparative tests, even offered to help them beta testing future firmware versions before making them available to general public. What did Asus do? They carry on releasing buggy firmware after buggy firmware. A few weeks ago a moron from technical support even told me Ai Protection always killed gigabit speed, as I wasn't using Ai protection with no issues for the last 3 years.

My RT-AC68U with 18881 firmware and pretty default setup performs excellent.
My WAN connection is "Automatic IP", wireless mostly 802.11AC right now, AiProtection disabled.
It may be that the issues are with PPPoE, but then it may be at the router end or at your ISP end. In general PPPoE can be quite troublesome and it is too simple to blame Asus.

I was too optimistic: the Status Tab still crashes the whole GUI, first freezing it then bringing up the Logon screen.

I also noticed this in the System Log, not sure if there is a relation with the GUI crash:

The router was working just fine with PPPoE up until firmware 380.7743. Then everything went wrong. Now I am not able to use both Ai Protection and gigabit connection, it's either one or another. I am sorry, but this is only Asus' fault and it's a well-known fact that PPPoE was always Asus' Achilles heel.

I had this crash in the previous firmware.

I called ASUS support and they asked me if I was accessing the router on wireless. I was. They asked me to access it wired and it never crashed via a wired connection, including in this latest firmware.

 

[RMerlin]

The problem is PPPoE and CTF here. At one point, Broadcom added hardware acceleration for PPPoE, so Asus also added it. There was however an issue related to IPv6, and if I remember correctly, fixing one breaks the other.

I've seen some changes to hardware acceleration in the past few weeks, but I'm unsure if it only addressed IPv6 or both.

PPPoE at 1 Gbps requires a fair amount of processing power.

Will update tomorrow, router will randomly 100% core1 crippling download speed since the last update.
hope this fixes it before i have to try a settings wipe.

Ok. I can confirm even connected to Ethernet cable it happened. Oddly when on the phone with support the other day it didn't crash on previous release.

I am glad my router is not unique
These system log entries appear after the GUI crash as result of opening the System Status > Status Tab:

Dec  4 19:38:47 watchdog: restart httpd
Dec  4 19:38:47 rc_service: watchdog 277:notify_rc stop_httpd
Dec  4 19:38:47 rc_service: watchdog 277:notify_rc start_httpd
Dec  4 19:38:47 RT-AC68U: start httpd

The GUI crash happens in both latest versions of Firefox and Edge.
All the rest the router is stable with performance as before.

My guest network (on 2.4GHz) broke somewhere between 3004380.7378 and 3004382.18881. I upgraded to each version until the latest. The guest net configuration is intact but it is not broadcasting. The regular 2.4 and 5GHz works.

PS Anyone know how to actually delete a guest network? If you "Remove" it only disables it.

Guest networks are working fine on RT-AC1900P.

As far as I remember you can not delete a Guest network once you configured one.
Revert to factory defaults is the only to way to get rid of them.
