Hiya folks I am hunting a widget to toggle between 5ghz and 2.4ghz, I am running a Carbon Rom and my router supports dual although my lovely Nexus will only connect to my 2.4 network if on auto, I have to use advance settings in wifi and select 5ghz only, so I would like to turn on 5ghz whilst at home at a flick off a switch!
cheers all43
I have a dual band router, and it has 2 separate SSID's - one for 2.4 GHz and one for 5 GHz. Can you just "forget" the 2.4 GHz network on your phone, or do you only see one network?
My 2.4 has better range (of course not speed) and all my 'other' wifi spots out and about are 2.4 only, also when in auto network my Nexus only sees 2.4ghz.
Edit
Bad manners...forgot to say thank you for your reply.
I'm on stock 4.4.2 rooted with franco r199 running on the .98 baseband. Using an Asus RT-N56U router (upgraded to the latest firmware - 3.0.0.4.374_979), running on both 2.4GHz and 5GHz.
When I first setup my router, I can get download speeds of up to 55Mbps using the 5GHz channel. Pretty good. However, in less than an hour, when I do another Speedtest, the download speed drops to 10Mbps.
My temporary fix is to tweak the Control Channel in the router, setting it manually to 40/44/48 etc. Right after a soft reboot of the router, my download speed goes back to 55Mbps.
However, the problem recurs every time, and it's frustrating that I have to always switch around the channels in my router settings page just to get my download speeds back up. The speeds before and after the drop are consistently similar.
I have tested on 2 other phones (Samsung Galaxy Note N7000 and Motorola Atrix). Neither of them has this problem with the router, and when the speed drops to 10Mbps for my Nexus 4, it stays at around 50Mbps for the two phones.
I tried flashing back to the older radios (.48, .84, .97) but the speed does not improve. Still requires the channel changing mentioned above.
I have used Padavan firmware for the router before and the problem recurs as well.
Any suggestion?
Just an update. My WIFI speed will temporarily go back up to 55Mbps when I go under Advanced under Wi-Fi Settings and toggle between Auto, 2.4GHz and 5GHz.
It's looks to me like an alternative temporary fix just like changing the channels in the router settings.
I mention temporary because the speed drops back to 10Mbps after a while.
i did the basic checking and didnt find any problems
i got galasxy s5 tmobile 4.4.2 android stock rom rooted
and it supposedly supports 5g wifi but when i use it the wifi just dies out after some time and becomes like dial up speeds.
facebook doesnt even load pictures or update
same thing happends with reglar wifi but after a longer period of time
im suspecting my router but dont know for sure i got a brand new modem router n600 c3700-100nas with 50mbps comcast connection
i already set it to free channel on both 2.4 and 5g wifi also checked all the settings on the router its all normal
ran the speed test on the phone but it keeps using wireless network to run it and gets 84.38mbps tops depending on the day
and when i switch to cellphone network its fast i got 3gb cap so i try to conserve
wifi at home sucks ass and at work i have an older router and its good there.
wifi analyzer shows signal strength between 50-65dbm most of the times
but wifi 5g signal strength is alwayss weaker for some reason
You are right, 5ghz band will always be weaker, the higher the band the shorter the range, so 2.4ghz(standard) will go mjch farther that 5ghz. If this is an issues with both the channels i would for sure check the router for issues, if its only happening on the 5ghz band i'd just stick to 2.4ghz unless you REALLY want to be on 5ghz.

is there any tools to test wifi that can tell me where the problem is?
ive been testing from my desktop and from cellphone best i can but my network skills are just slightly above noob.
i have some free tools on desktop for network troubleshooting but i havent used them yet(just downloaded)
on the phone i couldnt find many
im looking for some monitoring tools maybe ones that show graphs or something to show me whats goin on during the slow down times and what might be causing it.
if i remember correctly its not the wifi signal because that stays good all the time
There once was the option to set a preference on Android to use/prefer 5ghz over 2.4Ghz. It was called "Wi-Fi frequency band" in the settings. This feature has gone away and it looks to have been replaced with "Smart Wi-Fi Switcher," but that seems to be associated with Cell to WiFi transitioning more so than 5ghz to 2.4ghz transitioning.
The reason I am asking is that, in poking around, I learned that it's better to use the same SSID for 2.4 and 5ghz wifi.... consumes less resources and the client can "stay" on wifi better/longer by switching away from a weak 5ghz signal from the AP to 2.4ghz using the same SSID. (I'm not running mesh or WDS either....yet....) I took the plunge and named both SSID's the same on my router (running dd-wrt). I even took the time to make sure the beacon interval on 5ghz is shorter than 2.4ghz so clients will "see" 5ghz first and use it.
The issue comes when 5ghz goes weak the 6T moves to 2,4ghz- Exactly as intended and desired. However, when 5ghz signal is strong again, the 6T lingers on 2,4ghz and won't switch back to the 5ghz stream.
I know this is a well known issue on Android, but is there a good fix? (prefer no apps as a solution)
I'm running beta builds, and have developer options enabled. Though I don't want to mess with Root.
Any solution?
And yes, I know I can name the SSID's different, but the phone's handoff between the different SSID's is **** when out in the yard and buggers up my music/podcast/streaming.
To be clear off the bad, its not the router. Every other device in the house that connects to the 5ghz band works flawlessly. This is a brand new international phone being use with AT&T in the US, calls and texts function fine. Phone is fully updated and so is the router.
Wifi however is only picks up 2.4ghz bands. Not 5ghz.
Wifi analyzers pick up 2.4ghz but when switching to 5ghz I get a messages stating my phone does not support 5ghz. Anyone else with this issue?
@aq3e No. It doesn't have 5GHz.
2.4GHz has better penetration through walls anyway.
5GHz is really only good if you're in the same room.

I also dont have 5ghz and dont have the advacned wifi option to change bands... Why this model suck this much? Probably a OS stupid limitation...

The A20 does support dual band, but it's disabled. I tried to enable it by replacing the mx140_wlan.hcf file located at /vendor/etc/wifi/ with the one from the A30 and it worked, but there's a problem.
For some reason the signal range is terrible, to detect a 5 GHz network the phone needs to be next to the router, if it gets some centimeters away the signal drops at the point where the network is not detected anymore.

5ghz wifi is certainly not only good in the same room, check online heatmaps of 2.4 vs 5ghz to compare, it's not a huge difference. Given how much less interference you will get on the 5ghz it often works a lot better than 2.4ghz even at longer ranges. Fix peoples internet for a living and I've seen thousands of peoples speeds double or even triple from changing to 5ghz even when router is on the first floor and they use it on the second.

Read the article here.
It shows that 5ghz suffers from greater attenuation rates than 2.4
2.4 GHz vs. 5 GHz WiFi
Learn about when to use 2.4 GHz vs. 5 GHz WiFi with CenturyLink. The difference between these frequencies can affect your speed.

(I know this doesn't help much with the OP's question but to dispel hearsay I felt it needed to be said.)
I know you don't know me, but I said I resolve peoples internet problems for a living both on supplier and consumer side and have tested this with thousands of customers but you trust a random article with very little info more and don't even bother to look at heat maps? This article has been made by someone who read a blurb about wifi, but they did get one thing right...
"A lot of electronic devices and appliances use the 2.4 GHz frequency, including microwaves, baby monitors, and garage door openers. If you have many of these in your home, or if you live in apartments or condos surrounded by other people, that 2.4 GHz band is likely to be congested, which can damage speed and signal quality."
That list is very short, it also includes lots of computer peripherals, security cameras, smart home devices, walkie talkies, radios, remote controls, wireless handsets (landlines, not mobiles) basically every wireless device you can think of uses 2.4ghz and even your microwave! all these devices on a long range signal means your neighbours devices also overlap to combine together to make the 2.4ghz band for most consumers a disaster for anything requiring more than slow speeds. This goes without even mentioning that the 2.4 ghz band only has 13 channels (3 none overlapping) to spread every wifi device out on to stop interference, in most residential are this is simply not enough. In many cases this is so bad that even next to the router people can lose 80 - 90% of their speeds or have so much interference that even loading webpages takes a long time due to the amount of data being lost.
Like I said before, even if the 5ghz DOES have shorter range, it is not so short that you have to be in the same room, what would be the point? That is a something people assume because it's a "shorter range signal" but it's not that short! the 5ghz is usually faster due to it's naturally higher data rates and more consistent due to the lack of interference from intermittent signals. Most things that interfere with 5ghz are constant and therefore it's much easier to test and know what speed you can get in other rooms away from the router, unlike the 2.4 which has the same issues with passing through anything only with a load of other issues on top too!. The 5ghz also has the advantage of having over 100 wifi channels to spread networks out on to avoid them interfering with each other, a vast upgrade to the 2.4ghz.
Here is an example of a heatmap comparing 2.4 and 5ghz but just looking at any article that goes beyond a very brief description will show you why the 2.4ghz is often so much worse than the 5ghz.
What's the Difference Between 2.4 and 5 GHz WiFi?
What do these numbers actually mean? Does it realy matter? Is one better than the other? How many questions are we going to ask in this description?
socialwifi.com
2ldr - It depends on your house and nearby networks, test both bands with different devices in different rooms and compare speeds, outside of doing more thorough testing with other apps and equipment this is the easiest and quickest way to see which will work better.
You have 2 choises use BT modem BT modem Plan A: one Device in 5GHz network one device sharing Internet from BT modem feature. +Advance use Open Garden mesh client for better Internet throught BT modem. Construction of my plan:One or two devices in 5GHz WiFi network and 3 devices creating PAN network trought Bluetooth.if Your Bluetooth version is 5.0 you can use Mesh network profile. than using Mesh network structure. Mesh Bluetooth network structure helping one device to other. but you need to know you will use 2.4GHz trought BT modem and Mesh networks.

I fixed this issue on crDroidAndroid-13.0-20221126-a20-v9.0 by copying both mx140_wlan.hcf and mx140.bin taken from this a30 git. Works great on my a20.

Interesting. What's your A20 model? I believe I also tried to do that, but I'm going to retry it.
Done it on a SM-A205W.

No luck. I still have the signal issue
Do it again in the following order maybe ?
1. Download both mx140_wlan.hcf and mx140.bin from the git I gave you above.
2. Turn your wifi off.
3. Reach /vendor/etc/wifi folder using your favorite file browser ( Mine is Mixplorer ).
4. Overwrite both files.
5. Reboot your device.
6. Turn Wifi back on.
7. Do a Wifi speed test ( Wi-Fi Sweetspots app for me ).

I use a Magisk Module instead of directly overwriting the files, but this should make no difference. I believe it may be a hardware difference between our devices. On the schematics the 5GHz antenna seems to be marked as optional, maybe that has something to do.
I tried to put my device next to the router, and when I did it the network got detected (with bad signal tough), I could connect and the download speed oscillated between ~50-200 mbps (my network has 300 mbps). Once I moved further from it, the WiFi disconnected as the signal was lost.
