I am sitting next to the router.....
Samsung Galaxy S3 CDMA Rooted MetroPCS with Wi-fi on..
This is the speed sitting right here......next to to
Turned beamforming on/off on 2.4&5Ghz
so what should it really say/be?
When I am 20 feet away, inside, two walls between me the speed is slower, more like 39Mbps
I set the Output Power to 200mW on both frequencies too before getting the reading on speed from phone to router.

So what should it really say?

a 72 Mbps link is normal for most smartphones. Only the most recent ones support 150 Mbps links.

Throughput is typically around half of the link rate, once you take into account the encryption overhead, the shared nature of wifi, etc...
 
moto x supports 435Mbps. Not 100% sure its 435 but i know it is in the 400 range or at least says that is what it is connecting at.

Yes, a very small number of mobile devices have started to support 802.11ac, but his Galaxy S3 is of a quite older generation than this.
 
Just wondering because here inside my townhouse, built 1984 (wood studs, copper pipes, romex, dry wall) 20 feet away like right now,2 walls,I have a strong signal at 72Mbps
 
I have also noticed slow wifi speeds with galaxy s3 4g and rt68ua with latest merlin build. I haven't tested any other firmwares but I noticed that disabling some wlan option helped littlebit but not much.

Laptop in working perfectly with this build.

Galaxy s3 is much faster with different router.
 
My wife's LG F6 on 5Ghz, sitting next to the router is 135Mbps, on 2.4Ghz it is only 72Mbps
I have 2 Galaxy S3's, one is MetroPCS SCH-530 which I put the pictures up and the other is a straight talk CDMA-V SCH-S968C (for Verizon towers 3G only, that I use when traveling in other states)
Anyway when I connect to 5Ghz on the Straight Talk I get 150Mbps, on 2.4Ghz the same 72Mbps
I gave my kid a CDMA-V (Verizon) Straight Talk phone Samsung Centura, on wi-fi in 2.4Ghz (will not do 5Ghz) is shows 72Mbps also
On Samsung Galaxy Tab2 7.0 at 2.4Ghz it shows 65Mbps, on battery or plugged in and right next to the router

So I am beginning to NOT be impressed with this router....
Maybe I should just stick to a dual band
I don't need AC anyway

If the thought put can not be consistent :rolleyes: being 2 foot away

Now that Ubiquiti Edge router and Ubi-PRO AP are starting to look better....
simple plain router, commercial grade (not consumer)
I know from their forums that that produces 300Mbps and 450Mbps everywhere
and range of 400 foot
more than enough to cover my townhouse and not get any interference from neighbors wifi

The problem is more then likely with your clients and not the router. As previously explained your devices are a few generations behind and most only have single antennas which can't achieve full N/AC link speeds your hoping to reach.

Not only that but you have configured your wireless networks wrong, you should be using WPA2-Personal with AES encryption to reach full speeds.

I suggest you clear your nvram back to default settings and work from there as they are the optimal settings for this router and only configure what you know.

I personally have all my AC devices reaching 866.5 link speeds spread out all over my house (multiple floors) and can max out my 115/5 cable connection from phones/laptops. I can also get 50Mb/s wireless to lan speeds so unfortunately the issue isn't with the router but with how you configured it.

Ok
I will try AES only as right now it's AES+TPIK
and go from there
I am not looking for gigabyte speed
Just not 1X phone speed from my Wi-Fi in my own house ten feet Away
 
And I have 4G LTE on my phone so I expect the same or more on Wi-Fi
 
Here are S3 specs;
2.4ghz -72mbps
5ghz - 150mbps



I do see one issue though; everything is set to Auto on your router. You need to manually configure it.

5ghz
Wireless Mode - N+AC
Channel bandwidth - 80mhz
Control Channel - 153
WPA Encryption - AES
 
Ok thanks KGB7
I did that BUT
still sitting here next to it.......
still showing me the same speed
 
Power cycle the router and the phone.

Turn beam forming off on both bands.

I'll post screen shots of my settings later that you can try.
 
I have tried with and without beam forming
20/40 and 20/40/80 on channel width
had SNR go from 30db to 70db and all around
I doubt there is difference between AC68U and AC68R but still I am just not 'feeling' it with the RT68U. The linksys wrt1900ac that caused me problems, the SNR was better when it did work.
I am just thinking that the power output is only 200mW and there has to be some router, somewhere that can output 1 Watt
or a router that can be hardware hacked to output 1 watt...
that's what I am eventually looking to do BUT for right now
just a good connection that can give me better than 69Mbps-72Mbps when sitting next to it.
Still looking for what can be done
 
I just put the router back to stock firmware
3.0.0.4.374_5656-g8d0a991
and I am still getting the same speeds
ONLY if I make 5Ghz 80Mhz wide and sitting next to it (3 feet) I am getting 150Mbps on the Straight Talk GS3, wife's LG F6 shows 5Ghz @ 150 Mbps too. Usually it is showing it as 135 Mbps
I want to check the iMac's too, here that are wired to the router, well Dlink 'green' 8 port 10/100/1000 dumb switch then to router (wired).
Going to disable ethernet card/port and do wifi and see
these are NOT AC, just 2.4/5Ghz apples
My kids 2006 17" iMac on OS X 10.6.8 WAS connecting to the old Dlink DIR-655 wireless and also the Linksys WRT1900AC BUT for some reason it will NOT connect to the Asus router, on the internal wi-fi card.
Asks for password, put in the password, an then get Contact Network Admin, does not connect. I put in a UAC150 Amped Wireless USB wifi dongle (for Mac's with the mac drivers, disable the internal wifi, and it hooks up @ 72Mbps, and this is in the same room, and the software shows the signal it gets/sends at the max too.
It is this router.....
it is giving slower connections that the Linksys WRT1900AC that I had problems with, and not letting one of the mac's connect to it.
 
Also what does this mean?

I have a AdTrap (hardware) that is cable modem>AdTrap>Router
AdTrap is a physical Linux box that blocks ads on port 80 (does not work on https sites as of yet). It is a 10/100/1000 RJ45 connection, so the speed is there. The AdTrap also does DHCP for the router to it but not on the internal (after router) network.

Just wondering what that is....if important at all.

The Kernel DROP output is just the AC68R's firewall doing its job.

Also to be clear the AC68U and AC68R are exactly the same hardware, I have a AC68R myself and as I previously mentioned it works perfectly. (The R stands for retail edition for stores to stock IIRC)

I assume the adtrap box could be what is causing you problems, I suggest you remove it for the time being and connect your modem directly to the router and see if your issues persist.

Again to make this clear, the problem isn't with the hardware but its with your specific setup. Hundreds of others on this forum can use this router flawlessly so unfortunatly its something on your side that's causing the issue and if it is the 'Adtrap' box your unlikely to get a solution on this forum.

This is from a iMAc, sitting here on the desk, 5 foot away from router
It is connected both wired and wireless
it is a 2010 iMac 21.5" OS X Mavericks 10.9.4
Look at the transmit speed on the wi-fi
it's just 300 Mbps, at 5 foot.
If it wasn't wired thru a 1Gb switch then router it would be slow (wife is graphic designer so need to move large files to/from email/dropbox/etc)
I could not rely on the wireless @ 5Ghz
