Hi guys,
I'm still working on figuring out the connectivity issues of my O2X. My problem has been that my data connectivity intermittently drops out, and fails to establish one and move out of WiFi range.
I have completely reset my phone to stock with the latest updates available in Norway. This is baseband 622, and version number 10c. The problem I am consistently having is that whenever I have stayed on one connection type (WiFi or 3G/edge) for any length of time and then switch, the phone fails to establish a connection through the other service. This means that whenever I have been home connected to my WiFi for awhile and move out, mobile data is not established. Similarly, when I get home, it does not automatically connect to my home WiFi network. In both cases the solution is to turn on and off WiFi mobile data (sometimes several times) to re-establish the connection.
If I quickly moved in and out a range of my WiFi, the switches between the two connections without any problems.
This is with everything stock. Is there any point in trying the other basebands? I have tried a few of them already, but without consistently good results.
The alternative solution is to send it in for repair, but they will only tested, figure out that they cannot locate the problem because they do not have the funds stay with the same connection long enough, flash the phone with the latest firmware, and send it back. After repeat this three times, I'm entitled to a refund or a new device, but it means that I will basically be without my phone for around six weeks.
Any and all solutions are greatly appreciated.
Edit: I guess a possible solution is just to use Tasker or something similar to reset mymobile data connection when I leave WiFi, and regularly reset WiFi when on mobile data.
I believe I have the same problem.
The 3G data connection would drop about every 10 minutes.
I got the phone a week ago and it too came with 10c firmware and 0622 baseband.
I believe that this is a hardware problem because I have flashed other firmware + baseband combos and yet this same problem still occurs.
I have sent the phone back for repairs yesterday. I hope that they can fix this problem.
Again, its probably baseband related....
Same for me here

Hello,
Recently something happen to my mobile data connection. I got full signals bar H/H+ next to it but when try to use anything that need data connection, I got message cannot connect.
The data sending arrow shows but not receiving one. Usually turning off and on mobile data fixes that issue but not for long. At first I tough that is stamina related but it can happen even during browsing/facebooking so not sleep mode related.
No problem with receiving/ sending texts or calls, seems only data related. And no such problem over WI-FI, it maintain to stay connected all the time.
I recreated firmware using PC companion but nothing. I tried my sim card on other phone to find out if network problem but no such issue.
I have used generic .157 software after root without unlocking bootloader.
I got that phone for about a year without any problems, unfortunatelly bought second hand and no chance to send to warranty
Maybe anyone has some ideas to try.
Thanks
Do you use any apps for blocking ads?
I had porblems with most sites including google and its apps not getting connection. I finally figured out that it was the ad blocker i used and that i had to upgrade my hosts files again (even if there was no new update) in order to get connections working again. hope that helps

No I do not use any ads blocking apps. It occurs on fresh install, unrooted as well. Today suddenly stops playing spotify music and said connection error but for signal bars and H+ ;(
only thing i can think of is if you maybe have you data settings corrupted. That would cause your connection to not work. Does the internet work on some things but not others? And can you connect to internet with WiFi enabled?
Hello,
I recently flashed .575 on my Z3C, now WiFi connection is unstable, disconnects after a while. The consequence is that updates do not work correctly, file transfers through WiFi are often interrupted. Did any one notice the same behavior? Any fixes (tried different AP and to reflash the FW)...
Thx
Problem persists in 23.5.A.1.291
Similar issue here
I also have problems with the latest 23.5.A.1.291 firmware. There are two problems in fact, sometimes it disconnects and can't reconnect anymore without rebooting and the other is that, while it still seems connected to wifi, it's effectively offline as internet doesn't work anymore, after a while it starts working again.
It's a pity because the Z3C was the device with the best wifi and coverage that I've ever tried with the previous Lollipop. I partially resolved the problem, meaning that it happens less, changing a few parameters into the router, disabling every possible feature, still isn't completely resolved...

I'm not OP, however I tried that setting but it didn't improve much. After all, DHCP is a protocol which should be used only at connection startup theoretically
I also have the same issue, however installing Auto Wifi Manager seems to have helped -

Already tried but it didn't helped. As for the issue, for me it disconnects and reconnects instantly even with full signal every 5-10 min. So it does not eat my mobile data however every lengthy file transfert by wifi might be interrupted.
Tried different channels, 2.4ghz, 5 GHz on two different routers at home, on several public Wi-Fi AP, behavior is still the same.
If screen is on the connection stays but is sometimes interrupted and reconnects directly. If screen is off Wi-Fi gets cut for 2-5 min then reconnects (according to logcat, might be Doze? Wi-Fi is set to be always on). Tried also a full reset of radio settings.
Solution
Does not work unfortunately.
I might have a good news for you guys. I think I finally managed to solve the issue:
1) Download a Lollipop FTF
2) Open flashtool in Flashmode for this FTF and exclude everything except packages beginning with AMSS* (it will not alter any data on the phone and it's very quick, also does not need to regenerate the dalvik cache)
3) Flash
-> You just replaced the baseband / modem with the Lollipop one. Tested briefly on mine and so far no disconnections
Same problem here, after update to .575, and .291 didn't help.
Sometimes when I open WiFi networks phone doesn't find any network at all. Also bluetooh is acting weird sometimes (disconnects, can't turn on).
Tried with DHCP and clearing radio settings, and even downgrading to 23.4.A.1.264 and 23.1.A.1.28, didn't helped.
May be it is hardware related... I am on 4.4.4 and have same issues. On some routers better, on some worse. Also sometimes works ok for long time, next day same place disconnecting...
In my case, everything was OK until upgrade to MM

For me downgrading to Lollipop 23.4.A.1.264 solved the issue but as soon as I install Marshmallow, even a clean install by PC Companion the problem reappears. So I will stay on Lollipop for now, it also has Stanima
I think something is wrong with the way Marshmallow manages the WiFi connection

you're right. but luckily this problem can be solved! go to Developer options in Settings and check "Use legacy DHCP client". then reboot your device - problem solved!

This trick seems to solve another problem, for me it did not change anything in the issue
thanks
Has anybody had any problems with their WiFi not connecting? My device seems to fail to connect to wifi after a couple of days and just sits trying to connect. Toggling WiFi doesn't seem to resolve it, and I have to reboot the entire phone to get it back online.
No problem here.
Connects very quickly, never seen it fail to connect, even on my works dodgy BT homehub 3, which used to tie my old Z3 compact up in knots..
Yep.I thought that Snapdragon 835 cause this problem. Xi oami 6., ZTE z17 and Op5 had the same question with WI-FI connection.

I have a sd835 s8 and I haven't had any wifi issues whatsoever since launch. It's a sample size of 1, but I don't know if it's truly due to the sd835
I haven't had any WiFi issues. In fact my WiFi connections have improved using the XZ1 compact over the X performance (the X performance dropped its WiFi connections 3 times during my data transfer to the new phone)
I've had my XZ1c for about a week now (European model) and it connects to my home network (5G) normally. Signal strength is fine, although the galaxyS6 it replaced definitely had superior reception. I do have wifi issues, but only when already connected to the network. When the phone is asleep (screenlocked) it seems to lose an active connection. The wifi connection should be on at all times, even asleep. It will show the wifi symbol, but data apps don't load, and it will have lost the connection as remote for spotify connect (playing on my reciever). It will also switch to mobile data at random times with normal wifi signal strength (even though I toggled this function off in the developper settings).
I'm not sure if this is something that can be fixed through system updates. I haven't seen any forum posts with similar problems though, so I'll try to document what is actually happening before I contact Sony support.
I bought the US version and flashed the UK firmware to get the fingerprint reader to work. No issues whatsoever with this phone. No Wi-Fi issues, overheating, signal strength, battery, nothing. Everything works just perfectly.
Same issue here. Mine is Europe (NL) version. The upload and download speed can be very unstable. And especially when I take it a bit far way, even you see that it's connect to the wifi with full signal strength, it said internet is unavailable.
I'm not sure if this related to the system update of last weekend or not.
Further to my issue. My phone will drop wifi connection and repeatedly try and connect - it usually cannot see any other networks at the time. Restarting the wifi on the phone, or rebooting the access point do not help. Running a packet sniffer on the LAN shows no activity, which indicates the issue is to do with wireless handshaking.
The problem occurs every few days and the only way to resolve it is to reboot the phone, which fixes it instantly.
I contacted Sony and they told me to do a complete reset on the phone, this didn't work. I updated my findings and pointed out that it's seems to be a firmware compatibility issue. Of course, you only get to talk to first line, and as a reset didn't work, they want me to send it off for a warranty repair (which of course will be returned with "no fault found" as no doubt their wifi will be different enough for it not to have been picked up on day 1 testing).
I'm currently trying to gather a bit more information on the fault, e.g. does it only happen on my home wifi etc. I've disabled channel bonding but that didn't help, and I've not jiggled my DHCP settings after seeing plenty of posts describing wifi problems on Oreo for other phones.
It doesn't happen frequently enough and I don't have the time to delve deeply into the network to identify the cause.
One interesting thing was that it went funny at home, but it was working when I got to work. When I got home it still couldn't connect. So I suspect it's to do with a particular compatibility issue somewhere.
no problem here conecting to 5 and 2.4 wifis...

I haven't gotten around to this yet. Do you still have wifi calling and volte available?

So far my wifi has been fine...
Mine is worst, i couldnt get it to connect at all but all my other device including xperia xa, xzp, laptop, Ps4 PS3, everything connect without any issue whatsoever, already excahnged once and still the same.
Think mine is struggling with either a single access point or VLANs. I need to dig further, but that requires buying a new AP - this phone is getting more and more expensive!
exactly same issue as Dashers describes with my XZ1c. I am not watching it closely, but it seems that it is hapenning after around 2 days online. Never happened before on same network with my previous Z3c, which had run months without restart and any problems whatsoever (till its display died

I have more or less the same issues, and a reboot always solves it. It happens with both routers form ASUS and Draytek.
Additionally I see issues with Spotify connect dropping or not being found on my Sonos (hardwired to LAN), but not so much to Chrome Cast Audio on the same network.
I don't have a problem connecting to wifi, but I seem to have a different issue. Even though wifi scanning is toggled off in settings, my phone still seems to be scanning according to Battery Historian. I think this is one of several things contributing to my high idle drain. Does anyone else have this problem?

Have you turned wifi scanning off ?
settings\Lock screen & security\Location\Scanning - turn wifi scanning off

Yes, wifi and BT scanning are both turned off in settings and have been since the beginning, but both seem to be happening anyway according to Google's Battery Historian tool. When I go back in to see if they've been toggled on by an app or something, they still appear to be off.

I have this exact problem. One second its 100% signal and is workin as expected. The other second it just drops and tries to reconnect like crazy. I have even had moments when i am unable to find my wifi after said disconnect. All my other devices is working like normal on my wifi. Using Asus n66u 5ghz.
I have been having the same issues as mentioned above with my XZ1 compact(european). My issues with dropping wifi signal seems to be happening when there are two different wifi signals to choose from. They are both on my local network. One is an extender due to the size of my house. When it can detect both signals, it can't make a decision on which one to choose. Once I remove a device(forget wifi device), it stays connected to the other with no problem. Since it isn't trying to compete with the other.
Has there been any improvement on this issue?
I own the Realme 8 (4G) for my wife, and randomly happen that the phone does not receive or make calls (is basically offline) and of course is not in flight mode. After reboot also wi-fi has issue to connect to wi-fi at home on fritzbox router with 2,4 Ghz (it refuse the connection). It's strange if I open the a temporary protected guest mode, it connect without problems (it was using the same channel).
After a while or the morning after it reconnect to the regular access point again. It has occurred almost once every months since we got this phone (4 months actually).
I don't have issues with other devices at home, especially the problem with calls means a problem might be on the phone. I wonder it's a general issue to be fixed with software, otherwise I may call for repair in warranty. Anyone with similar issues?

After 2 years the issue is still there. The phone is updated to last firmware. I'm guessing that it might be related to the connection with certain SIMs.
