I did a search and didn't find anything. I've been updating my ZE551ML and keeping it completely stock. I am on the latest update (WW_2.20.40.97_20150917) and did a Factory Reset for a clean start. I realized after setting up my Wi-Fi again that speeds are extremely slow; <20 Mbps. This is on both the 5 GHz and 2.4 GHz bands, and even if I put it in the Performance Battery mode.
Is anyone else seeing similar and if so, did it start with this update or something earlier?
Is it because of the location? For me, Wi-Fi working normally (at least didn't affect my daily use) except for in my room which is not very far from the router. I get 3 to 4 bars wifi, but it will stop working for sometime and speed is very slow I can't even watch a video without being interrupted. If I walk out of my room, speed is back normal. It's like my room is protected against wifi

It is definitely something up with my ZF2. I have plenty of other devices connected to the same Wi-Fi network that get appropriate speeds. I'm pretty sure it also got great Wi-Fi speeds when I first got it, but this is the first time I re-checked the speeds after all of the various software updates since release, plus a Factory Reset.
FYI, after some additional testing as well as downgrading the firmware, this seems to be some sort of weird interaction between my router/access point and the ZF2.
I'm currently using the T-Mobile CellSpot (basically a ASUS RT-AC68 with T-Mobile custom firmware) in Access Point mode, and what I've been able to determine is that the ZF2 seems to be speed-limited when connected to the "normal" SSIDs (I have separate ones for 2.4 GHz and 5 GHz). I have configured guest SSIDs (which have Internet access but not local LAN access) and when connected to those the speeds are as expected.
Really doesn't make much sense to me since it is the same wireless radio on the router. But at least I can reproduce it definitely at this point.

My ZE551 ML is also facing some issues after the final update WW_2.20.40.97_20150917. Cellular data is not working. All the buttons are working and on but arrows are not displayed and no data transfer and status says Cellular network status-Disconnected.
poor clarity in voice calls to the receiver and slow system respond with even phone book app.
Expecting a kind support ....
I started this thread as a bug report in the Xiaomi forum, but no solution has been forthcoming.
http://en.miui.com/thread-2390770-1-1.html
I have also sent official complaints emails to Xiaomi at
[email protected]
Device: Mi MIX 2; MIUI Version V9.5.6.0.ODEMIFA; Reproduce rate: 100%; ROM version: Global Stable ROM; Country/Region: Nigeria
Description: Xiaomi Mi Mix 2 not reconnecting automatically from E to 3G or 4G after a call. It stays permanently on EDGE (E) unlike other Android phones that reconnect automatically to 3G or 4G after termination of phone calls.
Steps to reproduce:
1. Put Mi Mix 2 on 4g
2. Initiate or receive a call
3. Notice networks drops to E when receiving call.
4. End call.
5. Notice network remains on E after the call, and does not automatically reconnect to 3G or 4G as other Android phones do.
My post might be long, but it is due to the fact that I am feeling disappointed that I have not seen a solution in the MIUI and other forums.
1. My Mi Mix 2 does not reconnect automatically back to 3G or 4G after a call (when I initiate or receive the call). It stays permanently on EDGE (E) even with full 3G and 4G signals.
2. Before and after this update, I still have the issues of the Mi Mix 2 switching to EDGE (E) during a call and not automatically switching to the available 3G or 4G networks after the call; it stays on EDGE (E), which means that I have to manually restart the phone or go to the phone info (using the Internal memory steps to take change it to LTE or UMTS or WCDMA).
3. After manually changing to LTE, UMTS, or WCDMA, it still changes back to EDGE (E) during and after a call, and I have to go through the annoying steps once again.
4. From the forum posts, including the MIUI forums, I now know that this problem has been with the Xiaomi phone models right from the onset. I want to point out here that I never experience such issues with all the other Android phones that I have been using – none. They all reconnect automatically to 3G or 4G immediately the calls are terminated; I don't have to reboot the other Android phones to achieve this. That this issue has been with Xiaomi for a long time is beyond my comprehension. Why have the Xiaomi Engineers not fixed it?
5. The upgrade to the new MIUI Official V9.5.6.0.ODEMIFA (MIUI9) Stable version did not resolve this issue of the Xiaomi Mi Mix 2 not reconnecting automatically from EDGE (E) to 3G or 4G after a call.
I would like to find out if Xiaomi has come out with a permanent solution to this problem, and where I can find it? This does not happen with other Android phones/manufacturers. What is the permanent fix?
I have the same issue with my Mix 2. I have to go through all kinds of configuration settings such as testing>phone info (*#*#4636#*#*), APN, pulling SIM, inserting different SIMs, turning off VoLTE, etc, after voice call just to get LTE back. Newest MIUI 9.6.1.0 still hasn't fixed problem. Will never buy another Xiaomi phone until fix is released.
It's just disheartening to note that the latest ROM update has not resolved this issue. I am in constant communication with the Xiaomi Global Support team via emails, and will continue to be until they fix the issues.
Try LTE/CDMA/UMTS AUTO PRL
Works perfectly for me.

Thanks!
I started going through the list but didn't get to that one yet.
Switched the setting, made a couple of calls then rebooted, LTE & VoLTE both reconnected.
Will continue to monitor.
I had a problem with the signal too and i switched to this setting and it works like a charm.
The settings you had were for China so thats why it didnt work well.
PS. you have to manualy change the settings on every reboot. Remember!
**EDIT**
Forgot the random outgoing call issue.
Since getting my OP8P, it doesn't seem like any of the radio issues have really been satisfactorily addressed. I'm not sure if there is anything that can be done on our end to fix them, but I figured I'd create a thread to track them, and fix them if possible.
Please include your carrier, or any other differentiating factors:
MMS issues (T-Mobile): MMS messages do not come in reliably or at all with wifi enabled. SMS and RCS messages are not affected.
Fix: (Workaround) Disable VoWifi, which doesn't seem to work on as many APs as the OP7P and prior did. If that doesn't work, turn off wifi altogether to allow messages to send/receive.
--------------------------------------------------------
Wifi calling issues (T-Mobile): Wifi calling will not stay activated. Icon appears for about 30 seconds after turning on wifi. Also seems to be affecting MMS messages not sending/receiving when connected to WiFi, and potentially outgoing calls not going through reliably.
Fix: (Workaround) Possibly affected by APs that allow TKIP encryption method. Reports of only allowing AES/CMAK helping. TKIP has known vulnerabilities, but older devices may still require it be enabled.
--------------------------------------------------------
Wifi connection issues: Wifi seems to go dead 1-3 times a day. Wireless still shows a strong connection, but no data actually passes (SMS still works).
Fix: (Workaround) toggle wifi
--------------------------------------------------------
Poor 5G performance (T-Mobile): While this could be a T-Mobile issue, as they seem to have turned on 5G over most of our area using UHF bands (300mhz to 3ghz), performance is pretty choppy. Uploads seem to be more negatively affected, with speeds less than 1mbps at times. Download speeds can be up to LTE speeds, but often are not, and are almost always jumpy and not smooth during speed tests.
Potential fix: Disable 5G under: SIM & network settings > Preferred network type
--------------------------------------------------------
Occasion outbound call issue: Sometimes making an outgoing call takes 2 or 3 tries. I can't remember the error, off the top of my head, but it's something like "service not available".
--------------------------------------------------------
Can ONLY receive MMS on WiFi calling not on mobile data, SMS not affected. (details here)
Fix: use 3rd party SMS app, revoke all permissions from stock app, disable stock app

You can disable 5G in the SIM and Network settings ??*
With my old phone if I disable wifi it connects to Lte instantly and I can start surfing. With my 1+ now if I disable wifi it takes about 10sec until there's Lte but I can't start surfing. I have to switch from Lte to 2g and back to get it working. Same Sim in both phones

Good grief. I have no idea how I missed that. Thanks! I'll test and update the thread if LTE performance seems better than 5G. This very well could be a T-Mobile thing, since they just recently turned it on in my area.

I have noticed the exact same thing. I'm not sure why it takes so long... especially with dual-channel network acceleration enabled (and the fact that VoLTE is established before I shut wifi off).

My wife and I have similar problems with mobile data and wifi both occasionally showing strong signals but requiring a toggle off and back on before data passage resumes. Both OP8P and OP8. Verizon for carrier.
Well, I guess it's good to know it's happening on Verizon too?
Seriously, this needs to be fixed. If it was just one carrier, I could see it getting out the door. But more than one (very different kinds) of carriers is pretty ridiculous.
Issue: can ONLY receive MMS on WiFi calling not on mobile data, SMS not effected.
More details in my thread here: https://forum.xda-developers.com/oneplus-8-pro/help/receive-mms-wifi-calling-tmobile-t4088673
Fix: use 3rd party SMS app, revoke all permissions from stock app, disable stock app
Updated OP.
I've found that disabling Voice over Wifi altogether seems to help with the MMS while on wifi issues. I still get a few that don't go through and have to shut off wifi altogether, but it's much... much better.
I'm wondering if this is also connected to my outgoing call issues. I'll be testing that also.
**EDIT**
While I still think disabling VoWiFi helps, it is still very much a crapshoot whether or not an MMS message will send or receive. Between this and the dual sim issues, I may need to see if OP will let me return this.
No idea if it's related but in comparison to EE, three is absolutely crap. Truly a horrific network, 50% of the coverage and 59% of the speed.
Have noticed that the phone aggressively tries to hand over to WiFi even when I'm not connected.
Removing 5G from the equation helps a lot, least in my instance.

Curious, how are you seeing it's trying to hand over to wifi?
I'm so upset over this stuff. It would be more tolerable if OP had some sort of official status on some of these issues. Ignoring them won't make them go away.

Are you talking about the "Scanning always available" setting? I already have that disabled. I seem to be ok with 5G lately. Pretty sure the bad upload speeds are just due to T-Mobile working out the bugs.

Then you're fine. Don't worry about it.
I thought I'd chime in a bit with T-Mobile 5G. Minus specialized cities featuring higher frequency 5G, T-Mobile nationwide works off of the 600Mhz band, AND REQUIRES the 1900Mhz or 2100Mhz 4G LTE band to properly function at this time. So if you experience poor 4G 1900 and 2100 frequency in your area, but strong 5G, it won't work well for you, and you are better off doing 4G LTE 600mhz instead.
Call your local rep and confirm the strength for those two frequencies for you. Just thought I'd chime in about the poor 5G performance nationwide for T-Mobile for some. Nothing to do with the phone exactly.
My OnePlus 8Pro sometimes disconnects several times a day the radio conection. It's hapend with LTE on Telekom. 5G is not available yet. It's happend also in places where I have very good LTE network coverage.
Restart the cell phone is the only option to reconnect.
Switching OFF/ON the Airplane-Mode, reset network settings or a Full Wipe bring no improvement.
I have already replaced the SIM card against a new one by my network provider (Telekom) to rule out a defect.
I also have no problems with my previous device.
So I'm currently using my old device in parallel with a Multi-Sim.
A network fault therefore can be ruled out 100%.
The latest software version has also been installed.
The crash normally occurs while surfing the LTE network and is noticeable that the Internet is unexpectedly no longer working. The Radio display on the phone show me a few minutes more that i have still connection to LTE and than it jump to "no network" as already described, "ONLY" restarting the device allows to log in to the network again.
It was also tried with intelligent network connection or two-channel download acceleration on and off.
With WiFi the internet works continuously.
The Device runs with Stock-Rom.
I also have contacted the OnePlus Support, but maybe someone here has a solution for me.
Many Thanks

That is crazy. I think they may have fixed the wifi disconnects for me with the latest OTA, but when I did get them, toggling wifi worked for me. I never had to reboot over it. Your case definitely seems worse. Hopefully you don't have a hardware issue.

I have exactly the same issue with the same carrier (Telekom Germany) with 2 SIM cards tested. Gotten worse with the 10.5.9 so I rolled back to 10.5.8 where the issue isn't happening that often. I haven't got this issue when enabling data on my secondary SIM (O2 Germany). I have also tested the new Android 11 beta where I got shortly disconnected from the mobile network and then the LTE+ logo changed to "g" and everything was fine again. The phone was still connected to LTE with full DL speed (did the whole initialisation with mobile data + 20gb music download). However the beta is not usable at this stage. Since I have an unlimited data plan on that Telekom Sim I cloud test the **** out of it and it seems that the disconnect happens when the phone tries to change or adds the cell connection while using data. I have sent OP the required logs and after that they ignored me.. hope they going to fix this as it seems to be a software/compatibility issue with that certain carrier. Also 10.5.9 isn't really coming to German devices with ota so they might know about that issues.

Thanks for the feedback.
That the Problem with 10.5.9 got worse i can confirm. I loaded this Version in Germany by using the Oxygen Updater. But that gives hope to me that it is really just a software issue and no defekt on the device. So I will not send the device to OP for an unnecessary repair in the hope that there will be fixd with an update soon.
On the Facebook Oneplus page I have already heard from some people they have exactly the same problem, all of them use the German Telekom network.
Hopefully you get right, with that presumption, that 10.5.9 isn't really coming on German devices because they know the problem. So the fix will come very fast.

You guys haven't heard any buzz about 10.5.10 yet? I'm on 10.5.10 in the US, which I feel has been a lot more stable than the previous two versions (which had alternating issues for me).
The biggest issue affecting me remains the issues sending MMS while on wifi.
hello everyone, im having an issue on my poco f3 it happens on both miui official, eu v13 & 14
like title says, whenever switching from 3g to 4g there is no internet connection and i have to turn airplane mode on and off for it to work again...
you can trigger this issue by going to settings and manually changing to 3g and then back to 4g, but it can also happen automatically if the signal is low...
does anyone else experience this issue? is there any fix for this?

3 possible reasons:
1) When youre using 3g, your phone is connected to the best signal 3g tower nearby, switching to 4g makes your phone use the same tower (could be a low signal 4g). When you turn airplane mode on and off, the phone connects to the best signal 4g tower nearby.
2) Faulty SIM card
3) Phone faulty hardware

Thank you for your comment.
I dont think the SIM is faulty simply because when i insert it to my redmi note 9s, this issue does not exist.
does your poco dont behave like this?
