Hello everyone.
As a proud owner of Xiaomi Redmi Note 3 Pro, I have a problem that lasts for month now.
I actually have a Mi Band that is always connected via bluetooth on my phone, and i need bluetooth to be always on. The problem is that when i am on the 2.4 ghz band on my wifi, sometimes the internet speed drops to 1 mbp or less, as well as an high ping and totally unstable connexion.
The fact is the problem is totally random and not related to a specific use of the bluetooth (except for controllers apparently ). In fact, where i use a bluetooth speaker as well, i do not have any problem. The problem is not specific to my phone, as i had the same problem with my previous phone ( a OnePlus X ) and with my Onda Tablet as well ( Wifi is unusable when i connect for example a bluetooth controller ).
The problem totally disappears when i use the 5 ghz band or when i desactivate the bluetooth (but for a reason, the 2.4 ghz band seems more "sensible" of interferences ). For notice, my rooter is a dual band (2,4 Ghz and 5 ghz).
I have tried to change the wifi channel on my router, it's the same problem as well. The problem lasts for months now and really consumed my patience, as he appears totally randomly and with no reason at all ( except for controllers ). I have searched for answers but cannot find any satisfactory response, only some clues related more or less with my problem. I can live somewell with the problem but actually i need solutions or at least clues of the origin of the problem
Phone : Xiaomi Redmi Note 3 Pro (Special "Global" Edition)
Rooter : Orange Livebox Play (France ISP)
Thank you in advance for your help
Edit : I Know that Bluetooth use the same frequency as the wifi, but normally the bluetooth has been made to "prevent" such interferences. The fact is that in my case these interferences occur without any clue of their origin
+1 ... have you found a fix?
I also have the problems with wifi and bluetooth, but on the bluetooth mouse instead of mi band. As soon as I start downloading something, mouse cursor starts to lag. As I have researched the problem, the only real solution was to change wifi to 5ghz like you mentioned. Unfortunately, my router doesn't have 5ghz band, so the workaround I found was to change the Channel selection on the router from Auto to some other channel. The problem didn't disappear, but it's not lagging as much anymore.
Also, why don't leave router on 5ghz?

Just noticed that for me, bluetooth audio to a Sony Ericsson MH100 headset will skip and drop out for periods as WiFi is active in connecting/disconnection to a network, or actively transferring data.
- Tried PowerAMP with various buffer settings, but audio cuts out instantly when activating WiFi, so audio buffer doesn't even have time to run out, and music is still progressing within the played track as the audio cuts out.
- Tried Samsung Music player, still same issue.
This can happen in some phones/cases and is not uncommon, but it never happened with my SGS1. Are the WiFi and Bluetooth functions sharing the antenna now, and weren't in the SGS1? Poorly written drivers for the Stock ROM in the SGS2 (I was using CM7 for a long period with my SGS1)?
Anyone else care to test this, maybe there are some details that makes this preventable, depending on how the phone connects to certain networks or such? Currently I don't have any other headphones to test, though I mildly doubt that will make a difference.
BT & WiFi both use the 2.4GHz band, so interference between them is not unusual. If you can, try a different WiFi channel; it's usually a setting on the WiFi router/access point.
I've read that the SGS2 supports the 5 GHZ WiFi band, so that may be an option. However, I just tried it on my SGS2, with my Netgear WNDR3700 router, which has both 2.4 & 5 GHz access points. The SGS2 couldn't see the 5 GHz network, but works just fine with the 2.4 GHz network.
They use the same frequency, and many phones share the same antenna for Bluetooth and wifi too. My Nokia n95 would stutter Bluetooth music when I used wifi to load pages, due to throughput constraints I assumed at the time. Looks like this is still the case with phones.

Thanks for the reply, when you say that it works fine on the 2.4GHz band, it doesn't interfere with bluetooth audio for you when using WiFi? That's hopeful, I just hoped it wasn't a 100% limitation with the phone, that it constantly has to switch between either bluetooth audio or WiFi activity.
RIght, firstly I've got a UK Z2 (Vodafone model, but unlocked and subsequently flashed with a different ROM).
My problem is that I can't connect to a router that only operates on the following channels at 5GHz; 149. 153, 157, 161.
These are apparently valid in the UK, although my iMac won't see them - but it's a 2009 model. My MacBook Air (US import) does, and my Z1 Compact (with EU Generic ROM) does. So does my Xperia SP. The Z1 I recently sold did too.
Now I assumed that the UK ROM, and now my Taiwanese Z2 ROM (the router is Taiwanese too), supported it because when I turn on the phone, it can see the router. However, it can't connect. It never gets an IP address, and then soon after it disappears never to be seen again! That's unless I reboot, but even then - sometimes - it won't show then either.
The Wi-Fi signal is excellent.
I've read before (for the Xperia Z) that you need a SIM card inserted, and there is. It's a Three UK SIM. That perhaps tells the phone what channels to use? But if it thinks these channels are not allowed, why does it initially show the router? Is there a delay before it notices what can't be used? And why would one UK SIM hide the channels, but not another?
In any case, my Z1 Compact currently has no SIM card inserted but still works.
I'm very confused. It doesn't appear to be a hardware issue (it would be a weird problem if it was), so it must be down to the ROM - and I've had both .55 (Vodafone original and then a EU generic) and now the Taiwanese .69 ROM.
Sorry for the long post, but I wanted to try and pre-empt any questions that might get asked.
Basically, is anyone else having the same issue and does anyone know a potential solution? I can't change the channels on the router and there's no other firmware for it. Obviously I could change the router, but I think I'll just have to stick with 2.4GHz in that case.
I know you say no fw is available for the router but im assuming you mean stock? Is dd-wrt/tomato available for it?
My s3 was the same on every custom rom i tried, 5ghz was always iffy :/ Will let you know if 5Ghz works for me when my z2 arrives friday
5 ghz works for me but not using the mentioned channels, in fact my router Won't even allow me to use those channels.

The thing is, the router is from Taiwan and there doesn't appear to be any way to change the channels it operates on. For 5GHz, those four channels are it.
They do appear to be legal in the UK, but many devices won't support them.
I am just confused as to why the channels work on the SP, Z and Z1 Compact but not the Z2. And even more confused because it will show up for a little while but not connect, then disappear. That's an odd way of restricting Wi-Fi channels on the part of the handset.
Can you maybe doing a forget network and then re-adding it?
I'm in Singapore and have no problem connecting to 5Ghz channel 161.
I don't think it makes much sense for them to limit channels on the client side as people can travel anywhere with their smartphones and should be able to use any channel available..

Yes, but some devices do still restrict channels - based on what region you've set, and possibly in this case the SIM card.
I'll need to do further tests, like swapping the SIM for one, to see if that makes it work. At least then I might be in a position to report it as a bug to Sony.
I have removed/forgotten it when it was there, forcing me to re-enter the code, and it just doesn't connect. And while it isn't connected, it does then stop the phone connecting to anything else unless manually select it.
whats the make/model of the router?
Can confirm 5Ghz works just fine for me using Doom's kernel and Aur

I previously owned a Z1 and found that 5ghz wifi was very poor on this device.....I now have a Z2 and the wifi is exactly the same.......works well on 2.4ghz, but poor on 5ghz. My wife's Nexus 5 works well on 5 Ghz so it must be down to Sony's implementation. I am using channels 36-48 not sure if I can access the higher channels, I presume not....think my router only has the lower channels......I have searched the web before for an answer to the problem, but no luck as yet....:crying:
just to add my 2cents to this, My UK bt homehub doesn't have those higher 5Ghz channels highest is 128 lowest is 36
Yeah, this has happened to me recently aswell. I used to connect the 5GHz 802.11ac wi-fi network at home on my Sony Xperia Z2, but a couple'o days ago it disappared. I can't see the 5GHz signal, I'm using 2.4GHz instead. But my laptop can see 5GHz signal and connect without any problems. The channels on 5GHz signal is 149,153 by the way. And channels 11, 7 on 2.4GHz signal.
So what might be the problem within my Sony Xperia Z2?
Thanks in advance.
Oh I just relieved that this problem is not only for me... Okay as some people mentioned wifi for Z1 was poor and Z too... so it might be problem w/
design of Z series. I am using AC-7260 wlan for my PC and seeing 5Ghz AP. But not for Z2....
No jamming around my home, no one is using 5GHz other than my AP.
My Z2 works excellent on my 5ghz channel. I'm on vacation now so can't verify the channel I used. What I do know, is certain devices don't work as advertised with 5ghz. Just because one device sees it doesn't mean every device will. I've had to switch channels a few times for different phones although my laptop has always seen it.
Yeah, it must be the channel issue, I suppose. But at first, my Xperia Z2 was connecting to 5GHz signal without a problem... After a while this issue started. I didn't change any channels or something on my router, either. Interesting...
5GHz signals have inherently smaller ranges than 2.4GHz ones.
That said, my Z2 connects to my 5Ghz AC network just fine (range sucks though) but it has a problem keeping the connection to the 2.4GHz N/Mixed network from the same router (dualband ASUS RT-AC66U) alive after a period of time. It will still show as connected (with good signal strength) but will not have any access to anything else.

Yeah, I'm well aware of this range thing between two signals. But my problem isn't something about it. My phone used to see and connect 5 GHz signal, but it doesn't see 5 GHz signal at all now. Even when I put my phone right on the router, between 6 antennae. (3 x 2.4GHz, 3 x 5GHz antenna)
This must either a software issue, or channels on 5GHz signal... But no, my phone was connecting without any problems for 3 weeks with the same channels. Must be software.
This isn't my only problem with wifi anyway, there's also a Bluetooth interference with 2.4GHz signal. Happens when Bluetooth is on at the same time with wifi. And when connected 2.4GHz signal, connection drops sometimes.
i found this thread now i had posted one earlier today.
what I have figured out is - the moment the SIM is inserted Z2 is taking off the channels that are not "legal" possible in the country determined by SIM.
I am on Telkomsel - indonesia, if NO SIM - I am able to connect on 5 GHZ very well. but once it senses the SIM card, the 5 GHZ vanishes.
This never happend on Z Ultra!
next step is to test on other channels on the router in 5 GHZ to see if it is limitation of Z2. Right now my router supports only 4 channels - 36 40 44 48 on 5 ghz band.
otherwise my mac and other units connect and work pretty well on these channels!
Alright, I've had my Xperia Z2 for 3 months now. I've never connected to my 5 GHz 802.11ac signal before, the phone doesn't detect it. I can only connect via 2.4 GHz band.
Why my phone doesn't detect 5 GHz wifi signal? What's wrong? What do you suggest?
What ia the max link speed you get on 5ghz in z1 compact
I don't know if anyone with a Z2 still has this problem, but I did and I seem to have fixed it by not setting my router to VHT80, but to HT40 instead. As a side note, my Chromecast seems to be able to connect to it now, too. My router is a Netgear Nighthawk (R7000) running the latest DD-WRT Kong Mod.
Hello guys, I have 2 smartphones which are ''Samsung Galaxy Grand 2'' and ''Nokia 5''. Both of them supports 5Ghz Wi-Fi band. My router is ''Tp-Link Archer c50''.
The problem is both of my phone doesn't detect the 5Ghz band at all. There is no problem in the router. Laptops works well with it. I took the router back to the shop from where i bought it, they found out it's working with there smartphones (don't know the model though).
It's Good to say that my router only supports channel 36, 40, 44 and 48 of 5Ghz band.
I tested my mobiles channels by connecting each other via Hotspot and found out that they are always using channel 153. So i thought it was the problem. I also asked for support from Tp-link and Nokia's online care but they failed to help me out.
Now few days ago for some reason i installed cm 14.1 rom in my Grand 2 and there i found out that it's detecting 5GHz band but whenever i tried to connect the rom kept crashing. Anyway for whatever the reason i installed that rom didn't worked out for me so i got back to stock rom.
There i found out my Grand 2 is detecting the 5Ghz band in stock rom which never happened before. It was working well but after few hours it disappeared. From then after few hours mobiles battery got empty and it shut down. After charging i switched on the mobile and found out that its detecting again but after few hours it disappeared again. I restarted the mobile but this time and from then i didn't seeing the 5Ghz band anymore.
So, can anyone tell what's the problem!!!!???
Hi,
I have a new OnePlus 7T Pro (version 10.1.4.HD01BA) and I'm having wifi stability issues.
The wifi has micro-disconections which impact any application which needs a stable connection (ex: online games, file transfers)
The symptom is a short disconnection from the wifi network: the wifi icon on the top briefly shows a "!" to indicate the disconnection; then everything comes back to normal).
From what I gathrered from different tests, the disconnects only occurs when using wifi on a mesh network (e.g. Orbi) or multi-channel wifi router.
I have no stability issues when using 4G connection.
I also tested 2 different mesh networks, the OP7TPro Wifi is unstable.
When testing on a simple channel access point (ex: another android phone), the wifi connection is stable.
On the mesh networks which give me stability issues, my older OnePlus5 does not experience any specific problems.
I tried to wipe my phone to factory defaults but the problem persists.
How can I find out if this is related to a software issue or if my device is faulty ?
Thanks,
Hello, I realize, this thread is almost a year old. I bought this phone and I'm having the same issue!
It seems that it maybe is related to bluetooth being turned on.
Have you somehow solved this problem? I read many complaints over the net when googling, but all the suggested solutions don't solve the problem completely, the drops still occur.
The problem has been known for years and occurs not only in the OnePlus 7 phones. When we connect to WiFi 2.4GHz and turn on bluetooth, WiFi transfer decreases drastically, the solution is to connect via WiFi 5GHz if our router allows it. If not, only the mobile network remains.
Well, that's a pity, thanks for your answer.
I also noticed, that the bluetooth range is really poor with my bluetooth headphones in comparison to my previous LG V30.

Use 20Mhz channel on your router instead of 40Mhz, that should solve the throttle in speed issue on 2.4Ghz band

I first faced this trouble in my oneplua 6, so your point about this being a oneplus 7 series problem is wrong
Good day, everyone!
I recently attempted, but failed, to utilize my mobile hotspot to connect a friend's phone to the internet through the 5.0 GHz AP Band. The hotspot shuts off after around 7 or 8 seconds when the AP band is set to "5.0 GHz". For my hotspot to not automatically switch off after about 7 or 8 seconds, I had to resort to utilizing the "2.4 GHz" AP frequency.
I really want to utilize the "5.0 GHz" AP band on my mobile hotspot without having to worry about it shutting down every 7 or 8 seconds, since, although I realize that I will be limiting the bandwave to a smaller region, I will be getting better speeds for my mobile hotspot connections in return.
I read a potential fix posted on this oneplus thread (https://forums.oneplus.com/threads/wifi-hotspot-5ghz-not-working.959323/) that sadly didn't work, and provided you have ADB, the major steps outlined were as follows:
1. Connect ADB to your phone
2. Run adb shell settings get global tether_dun_required
- Take note of the value you get (I believe I got "null" the first time around)
3. Run adb shell settings put global tether_dun_required 0 - restart your phone to get 5.0GHz tethering
If it's important to know, I'm running build 11.0.1.12.DE18CB (OxygenOS) on a T-Mobile variation (DE2118) that has been rooted using Magisk.
If anybody is having this difficulty, or if anyone knows how to repair the problem, it would be much appreciated if you could respond to this thread.
Thank you very much.
Hotspot being all ****ed up and barely working is a long standing "feature" of OnePlus even on qualcomm, and Nord has definitely got the worst of it.
On my device (DN2103_11_A.20), the 5Ghz setting is ignored entirely, it always opens 2.4Ghz hotspot.
Weirdly enough, it does that even while being connected to 5Ghz AP at the same time which I didn't think was even possible. On most mediatek phones, if you use wifi connection, hotspot will insist on sharing its band - ie hotspot band is forced to the channel of the AP the phone is connected to and relaying internet from.
The 2.4Ghz hotspot on Nord2 runs very flaky (only ~5mbits to LTE connection running at 50mbits for the phone itself). Moreover, when not using LTE, but phone is connected to wifi (regardless of whether 2.4Ghz or 5GHz) that is relayed to "forced 2.4Ghz" hotspot, that wifi uplink will become flaky too: 500Mbit/s -> 5mbit/s on 5Ghz, 50Mbit/s->5mbit/s on 2.4Ghz AP. Meaning if you use your phone as range extender, internet will be severely slowed down on the phone itself, and become almost as sucky as it is for hotspot clients.
To top it all off, the issue of "disconnecting after 5-8 secs" occurs randomly for me even on 2.4Ghz, typically in AP relaying situation on same band as explained above. The hotspot toggle is not switching itself off in the UI though - the hotspot AP SSID disappears from the air, as if wisi baseband were repeatedly crashing or something.
The only workaround I know of is to disconnect from wifi, disable hotspot, enable LTE, enable hotspot, let people connect and *then* finally connect to wifi (which "reroutes" hotspot clients from LTE to my wifi uplink).
I don't see how DUN could be related at all here.
tl;dr: Don't bother with 5Ghz hotspot, since the wifi driver is so utterly broken for hotspot it doesn't matter which band you use.

Thank you for your reply ezdiy.
It is terrible to realize that OnePlus has a persistent problem with this, but considering the number of discussions I noticed about this issue (5.0 GHz hotspot not functioning), all on diverse OnePlus devices, I am not surprised. In addition, I wonder why "Nord" may have suffered the worst of such a condition.
The problem you suffer from is unusual. I wish I could assist you, but sadly, I am no expert in these things.
It is interesting, since, it appears that there are some circumstances in which my 5.0 GHz hotspot performs well (Doesn't switch off automatically after 7/8 seconds) and other instances in which it doesn't. Does anything like this happen to you regarding the phone hotspot, where it works better in some circumstances than others?

My apologies for confusion, as I missed your device is N200 (Snapdragon chip, on those hotspot doesn't suck as badly).
My device is Nord 2 5G 12G/256G (Mediatek Dimensity 1200). It's still interesting to compare notes about the hotspot bugs across diverse array of chipsets, though.
This at least hints its something wrong going on in OxygenOS itself.

I could tell where you were coming from, ezdiy, so don't worry.
At a first glance, I noticed that the OnePlus 6 and, as you mentioned, the OnePlus Nord 2 5G are both affected by the 5.0 GHz Band issue. However, there appears to be a general Mobile Hotspot issue among OnePlus devices, as evidenced by the OnePlus forums (From the OnePlus 5, to the OnePlus 8 Pro, OnePlus 9, and OnePlus 10 Pro 5G, among many others) and the OnePlus Reddit (Ex: OnePlus 7).
I'm genuinely curious as to what the issue is. It could very well be OxygenOS, as you suggested. Regardless of the issue, I'm curious as to how long it will take for OnePlus to truly resolve such widespread problems.
