AC68u after latest firmware poor wan to lan

[dudeman33]

Hello. After updating to the latest _18 firmware, I could no longer pull my full gigabit wan to lan. It seems to cap out around 620-650. This is with CTF/FA enabled.

I tried reverting to the _15 which was what was on it before, but the same issue persists even after restoring from settings backup which I did before upgrading.

I did a 30/30/30 reset, and I cleared JFFS and nvram after each flash. Any ideas on what might have changed, or what setting I might have missed?

Latest _20 firmware and _15 firmware doesn't mean anything. What are the actual firmware versions?

A 30/30/30 reset doesn't have any effect on Asus routers.

I would suggest flashing 384.19 Beta 2 for your router and follow the last two paragraphs of the link below.

There is no "_20" firmware. The latest release is 384.18_0.

I did a 30/30/30 reset

There is no 30/30/30 reset with Asus routers either.

Interesting, I would have sworn that it was _20. The one that I flashed a few days ago was:

RT-AC68U_384.18_0.zip

I did the nvram reset via ssh and formatted jffs, did a factory reset, etc.

At this point should I recovery mode and try it super fresh?

You don't need to over-complicate matters. Just one factory reset through the GUI is sufficient.

Well that's what I did after a fresh flash. I did a factory default reset, waited, did a power cycle, and I still can't get more than 2/3 of my wan speed. Had no trouble before the upgrade, and I would have thought that a reversion and reflash to the earlier with the same steps, factory reset, power cycle, and then restoring the settings backup would get me back to where I was, and it didn't. It's behavior is the same as the newer.

That's why I'm here asking questions. And yes, I did make sure the clock speed us set to 1000,800 as well.

and then restoring the settings backup

Don't restore settings. Set the router manually after factory reset and test again.

It this the default for your router model?

Yes, that's what I did on the new(er) firmware, and I tested again before restoring settings to test that as well.

800,666 is the default I believe, but I know that is what I had it at prior.

I am having similar issue too... May I know what is the "burden" of the router? That is, how many percentage drop would you expect if you connect via router and direct?

If I connect direct to modem, I can pull about 938 down. I could get >900 behind my router prior to this update. Now it seems to hard cap at 650.

What happens if you remove your overclocking settings?

I have similar to this my AC68U last week connected to modem it is slow sometimes fast and sometimes disconnected for a 5 seconds i have problem for a week i thought firmware problem or settings so i tried changing my router as i have a spare router wrt1200ac but its the same..THEN i bought a new Ethernet Cable Cat7 replace the old and now it works flawlessly.. sometimes you need to change your Ethernet cable if you use to hold the router changing cable inserting/resetting router coz you need to flip the router to reset. sometimes the cable might get damage from opinion and experiences.

But now so far it is really Good Very fast.

What happens if you remove your overclocking settings?

There was no difference in performance at 800 or 1000. CTF + FA shows enabled and CPU stayed around 3%

Any news of the topic ? In the last 14 days I got a 1000/1000 Internet connection, and had high expecations of this router. On WLAN to LAN I expected 900/900+

I did some testing and I get more or less 750/930.

I tryed same cables and test with a Icotera I4850, and here I get 930/930, so the speed is there, BUT ASUS eat some of the down speed.
