Hello,
I'm having an issue with my HTC one. When I make a fresh connection to my router I get up to 35mbit but over the course of about ten to fifteen minutes the speed drops down to about 2 to 3 mbps and has even got as low as .4mbps. I then turn the Wi-Fi off and back on and I'm back at full speed again. Curiously the upload speed is never affected.
Any ideas? No other device on the network is affected.
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.

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.
Back in oreo wifi speeds were fine but after the update i am getting low wifi range and the speed is very bad. I have other devices that have way better speed . Is anyone else having this problem? How to solve this?
Yes the same here..has the lowest signal from all my devices
Just,we will wait for the next 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

What roms have you tried?
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.

Was trying to help the op who posted just last month.
I've recently bought a new 5g router that its speed reaches up to 500mbps, I've tried it in every phone in the house and it reaches 300 mbps on the older phones and 866mbps on the new ones, though on my phone the speed seems to be capped at 96mbps, then it randomly speeds up after a while and shows me 433mbps, though whenever I restart the wifi, it's back to 96mbps again, and I go back to waiting to when will it be 433mbps again
I tried resetting wifi settings, I tried factory resetting, I even upgraded my imui to 12.5.9 from 12.0.10, it's still the same.
How can I fix that?
