2.4ghz WiFi disappears

My 2.4ghz WiFi at home won't stay connected on my nexus 6 and dissapears from my available networks list. Even if I select 2.4ghz only it dissapears. Don't think it did it with 5.0 that I remember. I use 5ghz in the house but my 2.4ghz reaches outside farther when I'm by the pool or doing yard work streaming music.
All other devices connect to it fine with no issue. Tried messing with channels but nothing. Any ideas?

What rom build and radio are you on? do you have any third party switchers and lan managers loaded on your phone.

Cm12.1, but also did it on the factory image. Does it on both 95 and 98 radio (currently on 98). No third party networking apps.

hmmm. not sure why it's just that channel. Only time i've ever seen 2.4 boot is on Ubuntu 14/15 HP, because hp wifi driver is generic . wondering if it has something to do with poll request. If it's doing it outside by the pool, you might be picking up neighbors strong signal. not a real answer, but a start.
Suggest, dl a wifi signal monitor, and watch the log to see what you were doing when it dropped.

I live in the middle of nowhere, neighbors would need one heck of a router to reach me haha. Used WiFi analyzer and walked my whole property and only saw a bit of one network on channel 8 so I put mine on channel one. It just disappears randomly. I can go to sleep and wake up on lte. Or be looking at the WiFi networks list and it just drop in and out. 5ghz is always there though. My WiFi settings are set to auto not just a specific band. Its super annoying.

well we know it's radio, since it's happening on stock and cm12. and with both radio's. I'd hate to say hardware, but that's what it is pointing too. Sorry. If nothing else is being booted, i wouldn't say router hardware.

I'm thinking its a conflict between my phone and router. It worked fine on 5.0 and the old radios from those builds. And 2.4ghz band at my work is perfectly fine. And we have over 50 access points that I hop around on all day to cover the whole building. So its a combination of my phone hating my router or my router hating my phone. Obviously both devices are fine. Maybe my router is racist? Could be a possibility.
Was just asking to see if anyone saw this issue and found a work around. Be it specific channel, speed setting, hz setting, wireless protocol adjustment etc. Its a netgear wndr4500v2. All the HP access points at work are perfectly fine. May be time to try a different router.

Ahh OK. So now good prob to figure out

Nexus 6 - WiFi SpeedTest Slower than should be.

I'm not sure if this is a networking issue or phone issue, but I think I got this narrowed down to a phone issue.
I currently have a 105mbps plan through Comcast and all is working well except my Nexus 6 WiFi SpeedTest maxes out at around 20-22mbps.
Currently routing with a WRT1200AC Router with both 2.4 and 5ghz bands enabled.
I am aware the Nexus 6 supports 802.11ac; therefore I connected to my 5ghz band network. The nexus shows i'm getting a solid 360mbps connection to the router. However when doing a SpeedTest it caps at 20-22mbps (I should be getting around 105mbps). I suspect no issue with the router as I tested with a 802.11ac supported laptop and was screaming past my 105mbps speed. Based off some google searches I found that possible causes were maybe some power saving features, those have been turned off.
Troubleshooting I have done:
- Moved my 5ghz band to different channels
- Tried different 5ghz channel widths
- Tested speed on 2.4ghz band (Same Results)
- Tested Another Nexus 6 (I tried running a speedtest with a family members N6 running pure stock rom/unrooted and same results as with my Custom Rom'd N6)
- Disabled Carrier Radio leaving only wifi on.
- Reboot Phone, Router, toggled wifi Off and on.
Any other suggestions? It would be pretty disappointing of Google / Motorola if this was the result of hardware capabilities.

Select a different server on Speed Test.

not seeing that issue here...

Android 7 - 5Ghz WiFi slow

Jun-3 2017 got OTA update a few weeks ago. T813 doesn't have problem connecting to 5Ghz wifi but on 5Ghz the connection is slow. Appears to be capped at about 10MB. Whenever I run speedtest while connected to my 5Ghz network I get 10MB uploads. Disconnect from 5Ghz, rerun speedtest and I get 80MB uploads. Go back to 5Ghz rerun speedtest, back to 10MB. Can reproduce this every time.
I guess I am stuck not using 5Ghz.

change channel to 40 (on router/AP).. and test,.

Found this in a different thread. Changed to channel 40 and speedtest shows upload speeds of 80MB. Netgear recommends using channels above 149 but I will stick to 40. Anyone know why using the lower band 5Ghz channels gives higher speeds than the higher band channels?

do you happen to be using a euro model in north america? what is your CSC and which country are you using the device?

On router (if possible) change channel width to 20 any frequency should fix wifi. Atleast for me this worked

After changing the routers channel bandwith, this thing goes from 10 mbps to 80mbps. They need to fix this. All my other devices max out at 235mbps on 5ghz. This tab is too advanced to be doing this.

Had the exact same issue on my new T713 and the channel width change from Auto to 20 worked for me on Asus router. Left the Control Channel on Auto. Thanks!

I had this same issue too. I had to turn off Power Save Support then I didn't have anymore 5 GHz slowdowns

Mine had the slowdown with Power Save off - the channel bandwidth was what fixed mine.

hey guys, my download speed is very slow on 5ghz wifi, but few time ago was working well, I dont know what happened. My macbook reach 120MB download and 10MB upload, but my galaxy s8 shows 10MB dowload speed. I tried change my channel width on router, but didn't work.

I'm finding 5GHz to be a real mixed bag across all of my devices - Tab S2 T713, 2 iPad Air 2's, Dell XPS 13 9350 laptop, a Lenovo desktop, 2 Dell desktops, and a Galaxy S7 Edge phone. Performance seems to be inconsistent and I see complete dropouts where the band isn't even visible on some devices. This is irrespective of distance from the router, an Asus RT-AC66U_B1, number of connected devices, etc. When it's good, I see 120MB/sec but other times it will drop off by 50% or more or will disconnect. I've pretty much reverted to 2.4GHz except when I get the urge to test 5GHz out again.

5.0Ghz wifi not showing after pie update.

So I bought note 9 two days ago and it was on Samsung experience 9.5, oreo 8.1. I have a dual band D link router which has both 5.0Ghz and 2.4Ghz wifi. But after pie update the phone is not picking the 5ghz band at all. I have reset the phone clear cache and also changed router settings.
I think its a software problem of one ui. Is any one facing this issue? Anying I can do to get back 5.0Ghz?
Any suggestion will be appreciated.

Not sure what is causing your problem, don't think it's anything to do with Pie update.
I have been using Pie for months and use 5Ghz wi fi without issues.
Also haven't read of others having similar issues on this forum .
Have you tried wi fi analyser app
https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer

Tried with app and still nothing. I have reset the phone, cleared cache and still nothing. Mine is a exynos model and it's update handled by Malaysian samsung team.
After One ui pie I don't even see 4k 60 fps recording in rear camera option. It's an awful update. So many things are missing. They need to work on one ui.

The 4K option is there. Click the 16:9 ratio then click the 1080P option. You're welcome.

Thank You . But I really want the 5.0Ghz band as my speed is super fast. I can download 2 GB in less than a min. 2.4Ghz sucks. I have just reset my router and still not picking 5.0 Ghz up.

Not sure what to tell you. 5.0Ghz works just fine on mine. And I've been on the beta since it was released and now on the official Pie. Never had an issues with it.

Try to change the channel and check.

I have had a similar problem before and since the Pie update. I use 5 ghz band in the same room as my router. 2 Apple devices and my LGV20 are connected to the same 5ghz band. I used wifi analyzer to choose the best channel which for me is channel 40. The other devices hold signal even after sleeping. My Note 9 (unlocked American version) sometimes just loses internet. There is an exclamation point next to the wifi icon. When I check wifi analyzer the signal strength is fine (lower absolute value than 60 or higher value than -60 dbm). The worst thing is once the exclamation point appears (meaning no internet despite retained connection to router) it will never reconnect to internet unless I turn phone wifi off and on. Resetting router has no effect. I reserved an ip for the Note 9 and put the phone on fixed ip so it won't get booted by another device. I'm at my witts end.

If you search the internet you will. Lots of us have wifi icon suddenly show an exclamation point next to it
This means good connection but NO INTERNET! This despite other devices on same 5 ghz network have no problem. Wifi analyzer shows good signal and no competing networks.
The temp fix is wifi off wifi on now it reconnects and everything is fine for 20 minutes or several hours but eventually the exclamation point is back. If it would reconnect or at least try to reconnect it would work but it just sits there waiting for me to do manually.
If we had Bixby routines like the GS10 I would write a routine to toggle wifi when there is no internet but the problem is the wifi IS connected to the router so there is probably no way to write that as a routine... and we don't get routines anyway.
I agree it isn't due to Pie in fact mine is slightly more stable since pie but still that damn exclamation point!

Every time I turn off my snapdragon U.S. version note 9, I have to stand very close to the router for like ten minutes before going upstairs to my room. I have to be standing close to it before it gets picked up by the 5gz wifi. If I do not stand next to it for 10 mins after turning my phone off then on, it will not pick up the 5ghz. I know that sounds simple, but it worked for me.
(I tried first: changing wifi channels, restarting the router, turning off the 2ghz and not the 5ghz, changed passwords for each, I mean everything.)
Hope that helps!

That might help the op who posted months ago and likely solved his problem or returned his phone.
No, as I explained mine always connects and may remain connected for hours or for minutes. It never disconnects. It remains connected to router but stops receiving internet randomly at any time (connected wifi icon with ! next to it
I only use wifi in the same room as the router. It is my mancave and I spend all leisure time at home in that room. I shut off the wifi and the phone before bed. I have unlimited lte data but 5 ghz wifi is way faster. 2.4 ghz is perfectly stable but no faster than LTE+

5ghz AC wifi has always worked for me on any channel, running openwrt on my tplink archer c7 router.
N960F running latest devbase pie rom.

That's good for you but no help to the rest of us. I guess one might deduce my phone is faulty but if so a LOT of Samsung phones have had this flaw for years back to the s7.. I figured if anyone in the world knew the solution he would be in XDA

Why don’t you downgrade to Oreo and see if it works again?

It was the same in Oreo. My phone is stock unlocked Note9 on VZW.

Solved: Galaxy S10 no 5 GHz Wifi

Just got my S10 (G973F) XXU1ASBA and I cannot see any wifi SSIDs in the 5 GHz band. Tried resetting network settings but still nothing. My S6, S7, S8 and S9 can all connect fine, but the networks don't even show up in the S10. Anyone else having issues?

There is no such thing as 5 Mhz wi-fi band.

5 GHz, not MHz. Sorry
