I have Note 4 SM-910T, Android 5.1.1 Stock with systemless root.
The phone's Wi-Fi always connects to 2.4 GHz. I have a 5 GHz network with 802.11ac also available from the same router, with the same SSID, but it is effectively unused. Even if I am 2 m from the router, 2.4 GHz is selected.
I have searched for settings to force or prefer 5 GHz, and all the suggested settings are not present in Samsung Touchwiz. Is there any other way to force or prefer 5 GHz?
Can you manually add your network name, with "-5G" at the end?
When I can't find the band, sometimes that's worked for me.
My network is:
"M.Heidegger" - 2.4
&
"M.Heidegger-5G" - 5.0
Hope that helps.
If it doesn't, I'm sorry.

If you create a unique SSID for 5G band, the device will not seamlessly switch over to 2.4 GHz when you move out of range of the 5 GHz network. By setting the same SSID for both, devices are supposed to roam between the best bands and APs automatically without connection interruption.
Sorry to chime in so late on this thread but the feature you're probably looking for is called "Prefer 5G" and it's on the WAP side. At least my Ubiquiti UAP-AC-PRO has the option and it works fairly well as long as I turn down the 2.4Ghz radio. Speaking of, try turning your 2.4 down to entice 5Ghz adoption.

Hey guys is there a way to get this to connect to 5ghz wifi when available but 2.6ghz when only that is available? My router does both frequencies at the same time but my phone chooses 2.4 when set to auto

if your router broadcasts both, you can force 5ghz by going to wifi>advanced>wifi frequency band>5ghz only.
I know you said you wanted it to connect to 2.4 when its available, but that makes no sense since both frequencies are always available, so you can force it to only connect to 2.4, or only to 5.

Hello robgee789,
If I understand you right, you possibly mean connect to 5Ghz at home but still use 2.4Ghz when out-and-about and it's not supported? Or when it's out of range in your house since the 5Ghz penetration through walls isn't as good as 2.4Ghz?
Your router should support having different SSIDs for 2.4Ghz and 5Ghz - since they're technically separate radios.
So you could have the following networks:
robgee789's WiFi
and
robgee789's WiFi (5G)
If you forget both networks, then connect to the 5G one first, then the 2.4 one after - your phone should prefer the 5G network, but still connect to the 2.4 if it's not in range. It just doesn't switch back very well when it comes back in range.
I could find the separate SSIDs but I told it to just use 5ghz the switch to auto and now it automatically chooses 5ghz over 2.4ghz cheers guys

Hi
I have a dual band router, and i prefer to have as many devices on 5ghz, as it performs A LOT better in my apartment.
Of course i know that the chromecast is 2.4ghz only.
I have this issue: When i start something (netflix, youtube, deezer) from a device on the 5ghz network, it starts fine, but when the tablets go to idle mode, very often they stop seeing the chromecast and i lose control of the content playing (although it is still playing). This is not an issue if i run the tablets on 2.4ghz.
Any ideas?
May have set the tablet to to only use 2.4ghz when you are using the CC. Settings are under advance I think under WiFi.
I know with my phones in the house we have to limit it to 2.4 instead of 5ghz or we don't even see the CC since the our router has 2 separate ids for 2.4 & 5

That's weird, I have my 2.4 and 5Ghz networks with different SSIDs and I can see the Chromecast from either from both my tablet and Nexus phone regardless of which frequency they're on.
Really? Hmm with our moto maxx's and both RAZR M (all unlocked and rooted running newest firmware). When we have them in only 5ghz mode we can't see the CC
Are you sure the problem is actually related to using 5 GHz? I've seen the same problem on my 2.4 GHz devices - loss of connection to the Chromecast a few minutes after starting a stream, and difficulty of re-establishing it to control the stream. Maybe something else has changed, or you're just noticing the problem now.

Mines started doing it the last few days as well on 2.4ghz only, only some apps do it, youtube been one.
it's been my experience that CC can only be seen across 5 & 2.4GHz when channel width settings match across bands.
having said that, i've resorted to isolating the 2.4 band for CC traffic only, keeping all other devices (except tablet doing the mirroring) on the 5GHz band. ever since making the change, CC streaming has been relatively flawless.
It's probably a WiFI signal reception issue in general.
Case-in-point, I also have a dual-band router with different SSIDs on 2.4 GHz and 5 GHz APs (you really should use different SSIDs except in special cases).
When my phone has strong medium to signal, I have no problem using Chromecast while connected to 5 GHz. Phone sleeps, wakes, still connected.
However, I just moved my workstation to another room where 5 GHz is weak. 2.4 GHz is still strong (lower frequencies travel better), though.
With my phone on 5 GHz, control of Chromecast was sluggish. Chromecast's playback was fine because it's still getting good 2.4 GHz signal.
My phone went to sleep, and when it woke it "forgot" it was controlling Chromecast - in fact, it could not longer see any Chromecasts.
I switched over to the 2.4 GHz network and Chromecast was visible once more. I rather use 5 GHz on my phone and leave the 2.4 GHz band uncluttered, so I might have to relocate/reorient/reconfigure my router now...
When I'm streaming and tab casting from a laptop, I connect it to 5 and everything runs smoother because the data stream is divided over two frequencies. However I find that the Nexus 5 screen casting feature is not as content to operate if I'm connected to 5 GHz.

After recently upgrading my family's phone's, we all now have 5 Ghz Wi-Fi capable devices, so I got a dual band AC 5 Ghz Asus router.
My broadband is rated at 20mbps down...ok, so testing with ookla speed test I'm getting the same transfer rates on either of the Wi-Fi bands (2.4 Ghz or 5Ghz)
I thought I read somewhere 5 Ghz is what you want, and should select that one....but now I'm understanding it has much less range but more bandwidth, but if I'm maxing out my 20m connection at 2.4 Ghz, what is the advantage of 5 Ghz?
(I hope this makes sense to someone who can reply)
5ghz is better if you are struggling with 2.4. Depends on how many mouths you are feeding. If you speed test near 20mb then don't worry about it cause ur not drawing a lot.
BAD ASS NOTE 4
2 things
1. Set them up as 2 separate networks with different names as passwords. Thus prevents devices from auto switching
2. As a general principal 5.0 ghz I'd better for streaming media and gaming, but does not go through walls well. 2.5 ghz is what gives your router is range. So anything that is streaming (eg. Xbox, chromecast, pc) you want on 5 ghz and close to your router, anything else you want on 2.5 ghz so it will work at longer range without losing signal.

802.11n on 2.4GHz can connect at a minimum of 72Mbps and a maximum of 600Mbps. Unless you spent a boatload on a router and live in the middle of nowhere and operate no bluetooth devices you're unlikely to get 600Mbps on 2.4GHz as it relies on having four antennae and a 40MHz block available. 5.0GHz is much less congested so you'll always get the full 40MHz channel and the speed is limited by the number of antennae on your router.
The Note 4 supports 802.11ac, which skews it more heavily in favor of the 5GHz band. 802.11ac can use up to 160MHz channels which can achieve a data rate of 1300Mbps on the 5GHz band.
Now, all of that is completely theoretical. I can tell you that my T-Mobile Cellspot allowed me to hit ~80Mbps on 2.4 and ~130Mbps on 5 when I had a 130Mbps connection. I switched to Verizon and took 50Mbps due to cost, and the router they provide will only hit 50Mbps on the 5GHz band. On 2.4GHz I see closer to 25Mbps unfortunately.
Basically, I would set it up at 5GHz and walk to the extreme end of your house. See if you can still speedtest at your full line speed. If you can, stick to 5GHz. If you lose signal, drop to 2.4GHz.
Thanks for the answers guys.
Here's the problem. I have an 802.11ac router at my apartment, with two access points, one of them on the 5GHz band, the other on the 2.4GHz band.
I want my N6 to be forced to go on the 5GHz AP every time, and shun the 2.4GHz AP. This is because at my apartment complex, everyone's got a 2.4GHz router, so even though my N6 thinks it gets a stronger signal in the 2.4GHz band, it will get ****ty bandwidth from the 2.4GHz bands, because everyone in my complex is watching Netflix at the same time. The 5GHz bands are clean, so I get get far more bandwidth there.
So how do I force my Nexus 6 to use my 5GHz AP, and not my 2.4GHz AP?
Yes, I know, you can go into the settings, and tell it to use only 5GHz APs, or only 2.4GHz APs. I'm looking for the setting that says "Strongly prefer 5GHz APs, and only use 2.4GHz when absolutely desperate." That way, I don't have to remember to go into the settings so I can get wifi when I go out for coffee.
I don't want to constantly fiddle with my phone. I want an automated way to make my N6 Do It My Way.
I used to be able to prioritize access points in Kit Kat, but Google thinks we're idiots, so they omitted that feature from Lollipop.
Also, being able to prioritize access points means your phone doesn't log into your neighbor's ****ty wifi that you used once when you went over for beer, when you'd prefer it used your own wifi.
Are there any Lollipop 5.1 compatible apps that let you do this?
Can you go on your router and rename the 5ghz band to a different ssid as the 2.4ghz band.
After that only have the nexus connect to the 5ghz ssid.

That's already done, though I found that the N6 "helpfully" automatically adds the 2.4GHz SSID, since it automatically detects it's going from the same device as the 5GHz AP.
How can it connect to the 2.4 channel if you remove it?
Like I said, make it only know/trust your 5ghz channel.
Completely remove the 2.4 signal
Just a quick question. Specs I found say a/b/g/n but my 5GHz won't show up. I searched the forum and found some people saying that 5GHz works, others say it doesn't.

Tablet WiFi specs : WLAN Wi-Fi 802.11 a/b/g/n, dual-band
The Tablet works well with 802.11 n 2.4 GHz and 5 GHz.
5 GHz is a frequency, it all depends on your area and the Interference Level. Everyone's router setting would be different.
Select 2.4 GHz for longer range, 5Ghz for shorter range but faster communication between router and tablet.
The most important of the two is that the selected channel interference level is acceptable.

Hey thanks for your reply but that wasn't exactly my question. I'm just confused that I can't connect to my 5GHz network. I seperated them in the router settings, so it should show up in the list but it doesn't. Only 2,4GHz.

Check your router settings:
All routers works differently.
It should be 802.11 Mode n
Band selection 2.4 GHz or 5 GHz
Bandwidth (20 Mhz for 2.4 GHz) (40 NHz for 5 GHz)
Channel ( select best with intererence level of acceptable )
Make sure SSID Broadcast is enabled.
