Got the Asus AC68 router but internet is slow Wired and Wirelessy

Got the Asus AC68 router but internet is slow; Wired and Wirelessy. Im using the CGN3 modem and was using the Linksys EA6500...to be honest the Linksys did the job right after plugging it in..am I doing something wrong?

Firmware has been updated after plugging in the router.

 

I have rebooted the Rogers modem and also rebooted the router and to no avail. I am on the 150/16 mb package with Rogers.

How do you connect to the Asus AC68.  Through a commercial Cat 5e / 6 cable or through house wiring?

I ran a Cat 5 from the Rogers modem to the router...Rogers modem is in bridge mode.

Re: Got the Asus AC68 router but internet is slow Wired and Wirelessy

Cat 5, ok, but that is a commercially produced cable, correct, not one that you made up, or ran through the walls of your home?  Just to be sure of the interconnection rate between the two, if you look at the back of the CGN3, specifically the LED for the port that the Asus AC68 is connected to, if the LED is yellow / orange, the interconnection rate is 1 Gb/s.  If its green, the interconnection rate is 10/100 Mb/s.  If the LED is yellow / orange, then you should be seeing the full data rate through that port to the Asus AC68.  If its green, then you run into throttling issues with the CGN3 firmware. 

 

 



Re: Got the Asus AC68 router but internet is slow Wired and Wirelessy

Here is additional food for thought for the wireless speed.  The AC68, like many if not most routers supports a multitude of standards and speeds that go with those standards.  Here's the list from the AC68 spec page: 

 

802.11a : 6,9,12,18,24,36,48,54Mbps
802.11b : 1, 2, 5.5, 11Mbps
802.11g : 6,9,12,18,24,36,48,54Mbps
802.11n : up to 450Mbps
802.11n TurboQAM:up to600Mbps
802.11ac: up to 1300Mbps

 

In theory, I would hope that devices negotiate the connected rates at their highest capability, but don't count on it.  Gdkitty has indicated the possibility of a device locking down to a lower rate than what you would expect.  So, to counter that possibility, you would have to examine what standards the wireless devices support and decide on what rate you want them to operate.  So, instead of selecting for example 802.11 b/g/n on the Asus router, which is a popular combo, you might want to select 802.11n as the operating mode, which forces the connecting device to run at 802.11n data rates.  You might have to survey your devices to see what standards and rates they all support, and then decide what to set the Asus operating standard at.  Just to note, if you set 802.11n as the operating standard, other devices that don't support that standard will probably not connect, despite everything else being set, ie, SSID, Passphrase, Encryption mode, etc.

I understand...but when I plugged in the Linksys EA6500..I just setup the WIreless security and I was getting average of 190 mb download speed and 17 mb upload...strange that I need to fiddle aroud with this one to accompolish the same 

Re: Got the Asus AC68 router but internet is slow Wired and Wirelessy

Ok, then I'm presuming you should see the same speeds as before if you are just swapping one router for the other.  Just glancing through the user manual, things to possibly check:

 

1.  QOS page 28.  Turn this off for now for test purposes.

2.  Traffic Monitor.  Page 31.  Can this be turned off?  Just wondering if the monitor function results in lower throughput.  A similar effect has been observed with Merlin firmware.  Turn the logging on, or other selected funtions and the throughput drops.

 

 

Other than that, I'm stumped.  Need an AC68 expert to chime in here with further ideas.

Hopefully someone with a AC68 can help me out..all those are off by default as I havent touched them,,

Re: Got the Asus AC68 router but internet is slow Wired and Wirelessy

Hmm.. that is odd.
When the new 250 plans came out.. there were INITIALLY some trouble with bridge mode and using 3rd party routers.. which WAS rectified with the latest firmware.


That would be my FIRST thing.. is it on 4.2.4.3?

 

Beyond that.. it should work... there were a bunch of people with the 250 plan who were having issues.. and after the firmware update, were fine... USING that router specifically as well.

tester2013,

 

I'm surprised you're having this problem with the AC68U with the CGN3 in bridge mode.  I don' t know how long you've had the CGN3 but if it's not on the current software version it can have sporadic performance issues.     As Gdkitty already suggested verify this first but need to be in gateway mode to see it.

 

I too tried out the AC68U with the CGN3 a couple of months ago but didn't keep the AC68U after trying it out.    I didn't find enough of an improvement from my previous RT-N56U to pay the extra $.  I have gone back to my ASUS RT-N56U with the CGN3 in bridge mode and getting about 200 Mb/sec on internal wireless speeds using 5 Ghz and going to the AC68U didn't improve things that much, so I didn't bother keeping it.   I'm only on Hybrid 60 so see peaks of 100 Mb/s download speeds with the internet and with consistency where I am, so the combination is working well for me at this point.   Not sure how Hybrid 150 or greater would behave though.   The software in both of these routers is very similar and default settings on almost all things work just fine.   The only thing I did was turn off the WPS feature as it's a weakness in all routers as has been covered in this forum before.

 

You say that it was working fine with the EA-6500 why did you upgrade from that?   Was it the expectation of extra speed from the AC wireless?     If the only speed that matters to you is to/from the internet I don't think AC wireless will give you much more than just plan Wireless N using 5 Ghz band.    That's what I found in my tests so far.    AC will provide some benefit but no where near advertized if you need more than about 200 Mb/sec on your internal network.    Others here may have had different experience but this is what I found in my testing.

Yes it had the latest firmware...I just had it exchanged a few weeks ago at the Rogers store...was having problems with the previous one..

 

I returned the ea6500 because I heard so many great reviews about the ac68...but I'm disappointed with the Asus router so far.

Well, that's too bad.   Yes, it does have great reviews.   I'm surprised that it would perform worse than the EA-6500 though.   That should be not be the case.   When I tested it, it worked fine for me so it wasn't worse but rather that I just didn't see enough of a benefit from it.   Outside of AC support I already had most of the same features provided by the AC-68u in my previous router software.   The AC68U has a dual-core processor that in theory should make it much faster in overall traffic handling but in actual use I didn't find it to be that much more useful.  Not sure what to suggest next.

I picked it up for $184 plus tax from Staples...I like the router but I just wished it would (should) outperform the EA6500.

Wow, that's a great price for it.   Normally they're in the $ 240 range.    I saw it go on sale for about $ 210 in the summer but at the price you got, it would be a steal.   I wonder if it's just a bad unit, although ASUS products are usually pretty sound.  

 

You could try and use it just in Access Point mode where you can locate it in an ideal spot for wireless and use the CGN3 as a main router/gateway with all wireless turned off.  

Re: Got the Asus AC68 router but internet is slow Wired and Wirelessy

Ok, have a look for this.  On the ASUS control panel, go LAN...Switch Control.  Look for a H/W Acceleration enable check box.  Select it to enable it and reboot the router.  This is a chip level function for higher data rates from what I remember reading a while back, and it isn't shown in the user manual.  The drawback to this is that some functions such as the monitoring functions and possibly port forwarding will disable this function.  So, it comes down to a choice, speed or functionality.  This came up in a previous discussion about loading Merlin firmware on this or perhaps model down router, and the decrease in speed that came with using the monitoring and logging capability in Merlin.

I price matched NCIX which had it on sale for $184.99. I am not able to find the HW acceleration, where is it under?

Re: Got the Asus AC68 router but internet is slow Wired and Wirelessy

Select LAN on the left hand side, and when the LAN tabs come up at the top, select Switch Control, which is on the top right hand corner of the tabs.

 

Here is a link to a review of the AC68:

And here are some of the control pages for the AC68.  The H/W Acceleration check box is in the second row, right hand screen:

It's a good suggestion but on my previous generation ASUS router, hardware NAT acceleration is on by default.   I would be surprised if it wasn't also on the AC68U.    

Re: Got the Asus AC68 router but internet is slow Wired and Wirelessy

And just to confirm.. its STOCK firmware on the ASUS, right?

(not custom MERLIN or DDWRT, etc)?

Re: Got the Asus AC68 router but internet is slow Wired and Wirelessy

I would think it should be defaulted on, but there are probably functions that turn it off without warning you that it is in fact being turned off.  That was an issue with the Merlin firmware.  There are about half a dozen router functions that would turn off the H/W acceleration.  With this turned on, the data runs through a specific chip, in and out.  When the function is disabled, part or all of that data stream is then run through processing somewhere else on the board.

 

Its too bad that the Asus user manual does not show the Switch Control page and its options.

Assuming you're running factory firmware, at latest version 3.0.0.4.376.1663, another suggestion is to run the router with QOS  in OFF mode which is also a default.   On Asus routers when I turned on this feature I found the overall performance actually degraded.   Counterintuitivie but that was my experience.
