Using RT-AC68U_384.14_2 - can handles 300 Mbps up/down?

[Ben_]

I just got upgraded to PureFibre 300/300, but my Asus RT-68U running the latest RT-AC68U_384.14_2 firmware is only capable of doing 250+/260+ instead of 300 Mbps. PureFibre tech support told me that with PureFibre I should be getting the full 300/300.

Are there any settings in the RT-68U that need to be done when switching/upgrading from 150 to 300? (I'm using the wired connection).

Thanks.

Check the router's Tools - System Information page to see if hardware acceleration is disabled.

If you're using anything like AiProtection, QoS, etc. it turns off HW acceleration and the speeds you're getting are consistent with one or more of those being used.

Some have turned off all optional features but still had no positive effects on increased speeds. What worked for them was to do a full reset to factory defaults and then a minimal and manual configuration of the router to secure it and connect to their ISP (M&M Config in my signature below).

AiProtection and Adaptive QoS are both compatible with CTF/NAT acceleration. Traditional QoS isn't.

For DSL, I believe the rule of thumb is to expect 10% below advertised/promised speeds (yes, I know you said fibre, but to WHERE?). I pay for 50/10 and this is what I just tested to:

Awesome to see Diversion blocking the Ad, don’t you agree? That may slow my connection down slightly (along with the QoS noted above), but it’s a price I’m willing to pay. So, needless to say, I’m quite happy to see the speeds I do.

HW acceleration = Enabled (CTF + FA) and I don't use AiProtection or QoS.

What else can I try? I already power Off/On both my modem and router many times....

Trying NOT to do a full RT-68U RESET, because it's been too long that I don't remember how the heck to do the USB mtm, Diversion + Entware!

L&LD, is it correct that "Save setting" (backup) and " Backup JFFS partition" should not be used for clean RESET?

 

[ColinTaylor]

Try plugging a PC directly into your modem (and then powering both off, waiting, and powering on). Then verify that your ISP feed is actually as fast as it's meant to be.

I get 380+ Mbps with my RT-AC68U.

@Ben_ correct, saved backup config files should not be used if you want a true reset.

OK, thanks!

Direct connection to ISP's modem also < 250 up/down, so I guess its not my RT-68U issue?

 

[ColinTaylor]

... so I guess its not my RT-68U issue?

Apparently not. Perhaps your modem isn't capable of those speeds?

It's also worth testing from a different PC, just in case that's the problem.

My ISP's modem ActionTec T-3200M is capable of up to 1 Gig, is there such thing as waiting to 24 hrs for whatever settings to sync?

I don't know much about VDSL. I think you need to talk to your ISP and get them to test your line.

Thanks for the reply, I just found out the culprit is "Firefox", using Google Chrome and the results are good 335/332!

Good job tracking that down! Was it a hunch or a systemic elimination of variables?

Yes, by elimination because the modem's internal test shows 323/302 (see attached) and I double confirmed by running multiple tests on Microsoft's Edge and getting 325/325.

Can you flip your modem/router over to Bridge mode? You'll lose those stats and options, but the Asus + RMerlin router is much more capable when it is control of the WAN IP too.

My ISP's modem T-3200M is always in bridge mode, the above screenshot is because I connected directly to the modem to run tests. T-3200M settings are always in bridge mode and Wifi OFF, using it like a dumb modem, hehe.

You are very intelligent and now I have to search Google for "What the heck is WAN IP and how to use them in Asus Merlin" !

It's always a pleasure chatting with you L&LD, so may smart *** here!

I like the idea of WAN IP control...tell me more please.
If I were to do this, what happens if there’s a power failure, will the router keep trying to connect until the modem comes up, or can the router be told to wait 60sec or so for the modem to boot?

By 'when it is in control of the WAN IP too', I meant that the router itself has an external (public) IP, rather than being double-NAT.

The Asus + RMerlin + amtm + scripts hardware/software options we have are much more powerful, secure and responsive than any ISP supplied modem/router I have used.
