Having issues with 802.11ac

My Note 3 is having issues holding on to my wireless connection. I have an Asus RT-AC66U running merlin firmware. It connects temporarily, then disconnects and says it disabled the network because the Internet connection is to slow. I have had 3 other 802.llac compatible devices working without problems. 2.4GHz 802.11n works fine. I'll dig in more when I get back home. Anybody else having issues?

edit:

Apparently this thing doesn't like 5GHz networks at all, and it doesn't even see ad-hoc networks shared from two laptops I have tested. I might have to get it replaced, as I haven't seen to many other people having problems. It is definitely a problem with the phone and not my network connection.

I have the same model router using stock firmware and had the same issue with the disconnects with my Note 3 while other devices were working perfectly. I powercycled my router yesterday and I have not had the issue return.....yet.

The WiFi on this phone is horrible. It says I have unstable WiFi meanwhile I am right next to the router

802.11ac won't be an official finished standard until next year, so, there's still room for improvement. New firmware for an AC AP and note3 should probably iron out bugs.

I'm about ready to upgrade to the Asus RT-AC66U myself (once it drops below $180 again), from a 2-year-old Netgear wndr3700 w/ddwrt. Will probably slap DDWRT onto it as well to compare wireless performance.

I finally have some time off to do some testing this weekend so I'll see what I come up with. I did notice that sometimes the connection would stabilize if i was sitting near the router and start acting crazy when I got up to do something. I disabled the "Explicit beamforming" option in the router and did notice an improvement. The top test below is with beamorming enabled. The bottom test was with it disabled. Still dropped a little in the middle but much better than before. I toggled the setting and ran the test a few times and was able to repeat the results, though this still might be nothing. Ill report back later with anything else I find.

Just for giggles, what's the phone ac speed? They're only doing 72 n 2.4, 150 n5. What's the ac5? Why don't they work on maxing n5 before jumping the gun.

Hello there... I just wanted to mention that i had made the jump to netgear ac1450 (ac, 2.4ghz, 5ghz) it was between that and the asus. But i picked the netgear because costco had a special sale on it, plus costco has awesome Costumer Service, and warranty in case something goes wrong... anyhow long story short, i am able to use both the 2.4 ghz and the 5 ghz without any hickups at least for now( knock on wood). although i would like more range it is definitely outdoing my linksys wrt54g which i had dd-wrt installed on both speed and range. From about 30 feet i get about 3-4 bars on the 2.4 ghz and about 2-3 bars on 5 ghz. also the signal is going through 2 ceilings. I will update if i experience any trouble, honestly i was a little worried when i received my phone because i had some wifi issues the first couple of days ( drop wifi and what not) but i haven't noticed it recently ive had the note 3 for about 2-3 weeks so far.

Interesting. Your Netgear appears to use the BCM4708 chip, whereas the ASUS uses the BCM4706. I wonder if the BCM4339 in the Note 3 is more compatible with one over the other. You would think that coming from the same manufacturer they would all be compatible. I am still running my phone through some tests, but so far it seems like there is something hardware/software related in this phone that does not like any 5GHz network I connect it to. Disabling explicit beamforming helped for a while, but the problem started happening again this morning.

just a quick update, i just flashed the latest firmware o my netgear ac1450 router which enhances/enables beamforming+ especially on 5ghz (from version 1.0.0.8 to 1.0.0.14) and i must say that my connection has improved further more its mostly on 3 bars sometimes 4 although i still seen it drop to 2 every now and then..

I returned the ASUS and ordered a netgear r7000 for a few bucks more. It should be here by Wednesday. I'll see how wifi works then, but I am not holding my breath.

RT-AC68R on 3.0.0.4.374_339 is good

I returned the ASUS and ordered a netgear r7000 for a few bucks more. It should be here by Wednesday. I'll see how wifi works then, but I am not holding my breath.
FWIW, I have the Asus RT-AC68R on stock firmware 3.0.0.4.374_339. My wireless on 5GHz has been solid. I did a Speedtest last night which came back with 29.3Mbps down and 3.8Mbps up, and this was sitting one room away from the AP.
Before flashing to this firmware however, the 5GHz would never stay connected and once disconnected, I would have to access the router control panel and make a change, then exit and the 5GHz would be back. But now, on the newer firmware, it's been very good.

I am using the RT-AC68U with AC I have no problems on my note 3. Only thing I guess you could say is a issue is every now and then the phone connects to WiFi and shows no WiFi signal but it connects and runs fine. If I reboot the phone the problem is gone. It happens like once every other week if that. I have the Comcast 300mbps down and 25mbps up connection. The highest the phone has done with WiFi is 165mbps down. This is on whatever the latest firmware is now.

Same issue here, I have Asus RT-AC66U and the Note 3 keeps disconnecting from the 5GHz while other devices are fine on wifi
I also experience this issue with my RT-AC66U. I think the problem is that ASUS hasn't put in the option to set the 5GHz band as 100% 802.11ac, so if anyone else is connected it has to drop down to whatever crappy standard is before it. The current 802.11ac routers are really designed to be bridged to a second one. The insane throughput lets you create a solid high speed 2.4GHz network across a decent sized area.However, 802.11ad is going to poop on everything.

Don't u have to change the SSID to make sure u are using the AC signal properly?
You have to chance the SSID to separate the 2.4GHz and 5GHz channels. If you wan't guaranteed AC you'd have to only allow supporting devices on that band.

This is my two cents.

I use RT-AC66U with stock firm ware. I set up two SSIDs one for each frequency. That way if one falls over it will connect to the other connection. In My experience the 5ghz works best.

There are mixed results in this thread. What works for one does not work for another. I don't think it is the router, the Note 3 just does not play nice with Wifi. In researching Wifi problems was not tied to one router it points more to the Note 3.

Since I set up two SSID I have found it more reliable. I also use Tasker to control my Wifi and reassociate the Wifi connection.

I also found this problem to be intermittent. I have had my Note 3 since the release and did not have problems until last month. For the last few weeks it seems to be more reliable.

FWIW, I also had a horrible time with TouchWhiz disconnecting my 5GHz wifi all the time, saying "Your WiFi is Unstable". I have a Netgear R7000 router, known for its awesome range, but still TouchWhiz complained even when I was getting 4/5 bars. Anyway, long story short: After switching to CyanogenMod a couple weeks ago my WiFi problems are gone.

e.g.: When playing GoogleMusic via ChromeCast in another room, I often couldn't even play half a dozen songs before randomly having my 5GHz connection dropped, which results in the playlist being stopped as well, and getting kicked back to the GoogleMusic "play something" screen. With CM, I haven't had a dropout yet. Soooo... clientside firmware matters, and this is something that Samsung might have a fix for down the road in their KK update.
