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.

Yes it's stock firmware and the latest stock firmware. I like keeping my equipments on stock firmware unless I see the need to go to a custom firmware. I'll have a take a look at the control and report back.

For those who were looking to price match you are out of luck as ncix just raised the price today back to $199. I guess I got lucky yesterday.

I only get these two options:

Enable jumbo frame rate: currently disabled

And Nat Acceleration: Level 1 CTF

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

hmm, looks like slightly different terminology, a little more specific though.  Only one way to find out, enable, reboot and test.  If it wasn't enabled and you did enable it, did it give you any warning about turning off other functions?

 

Here's a couple links to discussions on CTF:

Strange but the router is working perfect now. I didn't make changes to anything.

Now if I make any changes to the Jumbo frame and Nat Application will I gain anything?

Thanks for all your help

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

I would run a speed test, wired and wireless so that you have baseline numbers.  Then I would change one at a time, reboot, and retest after each change.  You should see a speed increase with the H/W Acceleration.  The question is, does enabling the acceleration disable some of the other functionality that you might have previously selected.  There is no info on that at all.  Looks like it might be an experiment and find out kind of issue.  But, if you are doing straight forward wired and wireless operation, nothing fancy, you should see a speed increase.  Of course that also depends on whether or not the devices that you are testing with can run that fast.  There is also nothing to indicate if Jumbo Frame and acceleration will work together, or if they are mutually exclusive.

 

Edit:  I forgot earlier to think about enabling Jumbo Frames on the receiving pc or laptop.  You will have to drill down to the Advanced Settings for your ethernet adapter to enable it.  Go Control Panel....Devices.....(Ethernet Adapter: Intel, Atheros, etc).....Right click to select Properties.....Select the Advanced Tab on the pop up properties panel.......Scroll down to Jumbo Frames and enable.  You will have to be in an admin account to do this.

Is there a Jumbo Frame option on my MacBook adapter?

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

hmm, possibly not.  I did a quick search and didn't find anything that indicated support for jumbo frames.  That was just a cursory look, so don't take that as definitive.

I'm still having problems...router worked fine for couple of days. When I do a speed test the, the highest download speed I get is 72 mbps..upload is fine...couple of days ago it was at 198 mbps download speed. Wired connection on my desktop is fine and I am getting well over 190 mbps. Wireless is the issue.

Possibly a defective router or are my settings not right...left it as is...I'm using a Note 3 wirelessly so I know it supports ac band...and I have a mac book pro which also supports ac band, desktop is Windows 7.

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

Was that on a 2.4 or 5 Ghz network?  Just want to be clear about the frequencies in use.  Have you tried the Hardware Acceleration setting and if so, what were your results?



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

It's on the 5 ghz network and yes hardware acceleration is set on 2...I just changed the frequency to 153

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

Can you provide a little explanation for "I just changed the frequency to 153".  The user manual isn't a great reference (personal opinion).  Food for thought, if you haven't already done it, recheck the acceleration setting to see if its been disabled by any other setting without warning you. 

 

Are you testing with your 802.11ac capable  Mac, and if so, in the RT-AC68U Wireless General settings have you left it on Auto, or forced it to use 802.11ac and the widest available bandwidth.  At this time I suspect that the widest bandwidth you can choose under 802.11ac will be 80Mhz, although you never know, maybe 160 Mhz might be available.  That would give you the widest bandwidth and highest data rate possible, but you have to keep in mind that for a constant power output, a wider bandwidth will result in a drop in range from the router.  So, you would have to determine by experimenting from your usual Mac location, what bandwidth setting will deliver the highest data rate, while maintaining enough receive signal power at the laptop.  There is also a check that occurs at the laptop with 802.11ac to determine if the channel width is clear for reception, which is then signaled to the transmitting router.  If the whole bandwidth is not clear, then a smaller bandwidth is used automatically.

Changed the wireless 5ghz frequency channel to that (they use different channel ranges than the 2.4)

The likely ness of I interference in 5ghz range is not likely though...

I have been a using my note 3 to test the speed using speedtest.net. It's seems that on the 5 ghz network the router is very picky on the frequency...after fooling around (after I had posted) it seems that 153 works well..acceleration is set to 2..

Would you suspect the router as being bad? I was thinking if getting it exchanged from Staples.

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

No I don't think it's a matter of the router being bad.  I suspect at this time that its more a matter of fully understanding the capabilities of the 802.11ac and knowing or determining how best to use those capabilities.  Normally with an 802.11n system I would advise people to go the the following link to download and install inSSIDer, which is a wifi monitoring application.  This will also cover the 5 Ghz range, but is not 802.11ac capable.

 

http://www.techspot.com/downloads/5936-inssider.html

 

That is the last freebie version which only covers up to 802.11n.  Congrats, you're the first person that I will indicate that you should go to inSSIDer's home page and spend the money to download the 802.11ac capable version.  With that you can have a look at the 5 Ghz ac environment to see what channels are available.  Here's the link:

 

http://www.inssider.com/

 

The site is a little strange in that you have to go down the On the Job selection at the top, and then down to the bottom of the next page to get to the inSSIDer4 option to buy.  There are other selections available if you choose to spend more money.  but for $20, its worth having an application around to help sort out the issue. Its on my list of other things to buy when I buy an 802.11ac router.

 

http://www.inssider.com/

 

Those channels are also used by other systems, so its possible, at your location, that you might be stuck with the upper channels, but the only way to tell is to monitor the whole channel set and see what it looks like in terms of availability.  Here's a link to a chart showing the 5 Ghz channels:

 

http://securityuncorked.com/wordpress/wp-content/uploads/2013/11/graphic-80211-acChannels-all.png

 

Using channel 153, it looks like the widest channel bandwidth available is 80 Mhz, so you could set that on the router, and see what your results are. Just keep in mind the range decrease that you might experience when you use a wider bandwidth.

 

Here is another interesting link on Dynamic Frequency Selection that covers usage in the 5 Ghz band.

Edit:  channel chart link fixed
