Oneplus 3 - Issues with 5GHz WiFi? - OnePlus 3 Questions & Answers

Hello,
I seem to be having an issue with connecting to my 802.11ac router (Apple's Time Capsule). In "Automatic" mode, it connects to my SSID via 2.4GHz only. When I go to Settings > Wi-Fi > Advanced and choose Wi-Fi Frequency band as 5Ghz it finds 0 networks in the area.
FYI - I'm on 3.1.3 OxygenOS.
Is anyone experiencing similar issues?
Best,
Mash
Edit: To be clear, I have several devices including my laptop that are connected to the 5Ghz band. I've also used a WiFi scanner in my old S6 Edge to verify that there are SSIDs broadcasting in the 5Ghz band.

I use 5 GHz network at home and it works fine with my op3.

using 5Ghz on Fritzbox, i also use diffrent ssid names for 2,4 and 5ghz and also different passwords

Thanks guys. Are both of you on 3.1.3? I'm trying to isolate the issue here...

Got a 3TB time capsule here. OOS 3.1.3 - on automatic, it only connects to 2G despite having full 5G signal, however if i switch it to 5G only, it finds both main and guest networks in that band and connects fine Try re-flashing stock rom

Thanks - I'll try and do a nandroid backup and reflash to see if that fixes the issue.

3.1.3 stock, not rooted

Check what frequency and channel width your 5ghz band is set to, one time I changed my 2.4ghz and my ps4 couldn't detect it til I changed back.

Just tried 5Ghz without issue using channel widths 20Mhz, 40Mhz, and 80Mhz.

Thanks guys. I wonder if I've got a lemon.
I've just reflashed 3.1.3 and even then can't find or detect ANY 5GHz SSIDs. This is so frustrating.
I guess a call to support is the way forward.

Check if you are able to connect to a different 5GHz Network. It _might_ be an issue with the router itself.
Mine OP3 connects to 2.4 and 5 without any problems (TP-Link Archer C7).

Try going into advanced wifi settings and setting your network mode to 5ghz only. Inconvenient but will do the job.

[Q] can not connect to 5GHz band WiFi

Since a few days in can not connect to my 5GHz band WiFi anymore. Connection to 2,4 GHz band networks works fine.
I'm running Stock ICS 4.0.2 (rooted) with baseband XXKL1. Does anyone else have this issue? My router is a AVM FRITZ!Box 7390 but I don't thinks it is related to it because my both notebooks work properly with 5GHz.
may be a stupid question ,have you checked the phones wifi setting.
Which settings do you mean exactly? Frequency ist set to auto and when I scan for networks the 5GHz WiFi shows up but I can't connect.
would it be the baseband that you flashed affected it.

No internet access after switching between Asus RT-AC66U and data

I have no internet access on one certain wifi router (asus rt-ac66u), with my n7 lte, although I can access the internet on other routers and through the dataa connection, I can access my router management though. I did a factory reset of the router and that solved the problem temporarily but the problem came back. Just switching router/tablet on/off doesn't solve the problem
edit: well after turning on/off the n7 wifi worked but now data doesn't work when I disable wifi

If flashing the latest firmware doesn't help. You can try and change the wireless mode of your router. Log into mgmt. Navigate to your wireless settings, change "wireless mode" from "auto" to "N Only."
It's worth a try. What that will do is force N band only, whereas on auto when a g/b band connects the router switches to b/g mode, and that might mess with the Nexus. If the problem you encountered was fine with a factory reset temporarily, all it would take would be a "g or b" band device to log on to kill your n band and dumb down to g/b band.
It's not a bad idea if you don't have any b/g devices to turn off 'auto' anyways. The jury is still out on whether or not it actually benefits an all "N" environment, but it sure as hell won't be switching to G or B on you.
Those routers had issues with their early versions of firmware. They might have straightened it out by now. Upgrade it!

Try changing the WIFI channel used in your router. My nexus 10 had issues on certain channels especially on 5GHZ.
You may also have a Wifi region setting somewhere on your nexus. I remember seeing it before but can't find it right now. The region basically locks your nexus to (possibly) the wrong channels. IE. Not all euro channels work with american wifi channels

I tried different channels and connecting to 2.4 GHz only.
Help!
HELP!!
Let's divide the problem into smaller pieces - is this an N7 LTE problem or ASUS router problem?
Get another router (I use the Asus RT-N66U) and test if it works with the N7 LTE. If it does, then it's your' router.
If it does NOT work wit hth eN7 LTE, then it's your N7 LTE probably have a bad chip.
I installed the kitkat factory images and the problem still persists :crying:

[FIX] Wifi connection drops

I just discovered this with a little research with people having similar wifi problems. Simply change your router settings to 2.4 ghz band instead of 5 ghz band. For some reason the G4 is having problems with 5 ghz bands.
Or if you cant do that, just connect your phone to the 2.4 ghz band of your wifi if your router is dual broadcasting.

I'm trying it, not sure if it'll work. I've had 2.4 and 5 networks saved, i've just deleted the 5 network, we'll see if it's better.
Adding this line to my build.prop seems to have fixed this issue for me. I'm still testing but my phone isn't having any issues on the 5Ghz AC band.

Didn't work for me
not connecting to 5Ghz is NOT a fix at all..
i didn't tried the scan intervall, i'll test it.
but i can confirm that either the reception is low and that the phone love to loose the signal :/
It also sometimes says that it has bad internet conneciton, so it refuse to connect (didn't found the setting to disable this stupidity... I know that on stock android under wifi settings you can disable this behaviour)
Sometimes it is also refusing to connect to a wifi... it just say registering and stoped...
only way to force it : reboot the phone...
hope that a software update will fix these issues.

5ghz wifi connection?

Hi all, I can only connect to 2ghz wifi, 5ghz wifi does not appear at wifi settings. I remember when unbox the phone I connected to 5ghz wifi, but now no. I'm dreaming or anything goes wrong?
Edit: done a reset in recovery mode and 5ghz wifi appear in settings. I will not restore a previous backup
Edit2: I finally found what happens, if you untick the 5g in SIM settings the 5ghz wifi band stops working. And if I active the VolteHD I can't identify the contact.
Edit3: No working 5ghz wifi after 10 minutos standby.
Best regards.
Ill tried this but didn't work more than 10 min.
Any idea why this happens?

Yesterday, I did a safe reboot to the phone and I got some hours of 5GHz band connection without issues.
Today, I turned on the WiFi on the phone (I sleep without it activated), and connected automatically to the 5GHz band.
But after 30 minutes has passed, the problem showed again (no 5GHz band, no 5GHz neighborhood bands).
My old phone still reach them and can connect to the 5GHz networks.
Really annoying bug. Also, it seems it's nothing related to the 5g button / mobile network settings
I'm connected to 5ghz just fine, however personal hotspot only works on 2.5ghz.

you are the only man in the world! check in properties of the wifi the speed and you will see that is connected to 2.4ghz. Only one question more, do your wifi have two ssid, XXXX and XXXX5g? or the ssid is the same for the two bands?

I have two ssid, and i have two passwords for each ssid. In my home only works WiFi 5ghz and i have the mobile data off. If i'm the One i don't no, but is true for me the WiFi network os perfect for now.
Guys I'm on North America version 3.08 and I have no 5ghz Wi-Fi issues at home. I have 5G enabled and my VoLTE / caller ID is working perfectly on T-Mobile as well. My Wi-Fi has two ssid, XXXX and XXXX5g with the same password.

I have the same problem with 5ghz wifi. It happened randomly from time to time in not able to find and 5ghz ssid. The only way to make it work again is to restart the phone and my phone will be able to see and connect 5ghz wifi.
I also have no problem with 5Ghz WiFi issues. Mine is NA/Asia version 3.13 8/128 variant.
Similar issue 5ghz hotspot
I did not have problem connecting to 5gh wifi, but i had another issue where my other devices supporting 5ghz band could not detect my 5ghz RM5G hotspot. I found a solution in this website for another problem but it solved this issue. Just switch the sim from slot 1 to slot 2 and restart the phone. This fixed the problem for me and all my devices detected and connected to the RM 5ghz hotspot without problems. Maybe this would work to make the RM detect the 5ghz wifi.

Question 5ghz WiFi Issue

I bought a Poco F4 (global version, xiaomi.eu 14.0.5.0) about one month ago, I haven't had any issues with it whatsoever, save for the fact that it suddenly won't detect my 5ghz WiFi networks (my main router + a repeater) - and I'm not even sure if this is an issue with the phone itself.
I'm coming from a Samsung Galaxy S20 FE, which was known to have this issue, but to have this happen on 2 different phones is really weird. If I recall correctly this issue started to affect me after I changed my ISP.
The only ways I have to detect the networks again is to go the debug mode and use the WiFi Sniffer Test Tool or reboot the phone, which was more or less the same thing I had to do on the S20 FE (I had to go turn on airplane mode try updating the firmware via debug mode).
What I've tried so far to solve this issue:
1. Changing the channel of the 5ghz WiFi
2. Changing the bandwith from 20/40/80 to 20/40
3. Setting "Use Device Mac" on the phone's network settings.
4. Turning off WiFi Scan Throttle
5. Changing the bandwith to 20
All of the above methods, save for the last one, did not work. And while it does work, it limits the speed of my internet to bellow 100mbps.
The issue is not related to the WiFi coverage as well since it only happened when I'm on my own room, which is where my router is located.
I don't know if I can detect other networks apart from my own since even when they 5ghz detection is working I can't find any of my neighbors' networks. I'm unable to create a 5ghz hotspot on my S20 FE or on my old Redmi Note 9S for some reason.
I'm at a loss on what to do, it happens on both stock and xiaomi.eu, at least and at most once per day.
If anyone else is facing the same issue or has any suggestion on what I should try next please let me know.
Thanks in advance.
I have no problems with 5G Wifi on xiaomi.eu rom
All the time 300Mbit/s
Buy Wifi6 router
This doesn't look like a problem with the phone (s).
Try connecting to another router to see if you have the same problem.

Thank you for your input. I'll try to turn on my old router when the issue happens again. I find it odd that the issue affects both my main router and the one I use as a repeater, but everytime I made any slight change on the main router, the other one's signal almost immediately disappears to apply the changes as well, so it's probably that.

No issues at all. Great internet speed on wifi connection.

The problem is indeed with your router + repeater setup. Your phones are fine.

Thank you! I'm almost certain that the issue is that the bandwith isn't fixed at 80mhz, it's 20/40/80mhz, and when I had the bandwith set to 20mhz I didn't had the issue.

Thank you! It's probably related to the bandwith. I was able to turn on an old router and my phone was able to detect the 5ghz network after the bug happened and my router + repeater signal was missing.
Have you tried resetting your router to the default settings? Or maybe set a specific IP address on your phone in your home network? As said above, it is a setup issue of your network most probably..
