internet connection problems - Xperia Z1 Compact Q&A, Help & Troubleshooting

Hello,
I,ve got that problem with my z1c for a long time. In fact, since i own this device.
It has a problem with connecting to the internet, lets say, every fifth attempt to connect. Then the icon changes constantly from h+ to 3g+ and back. You see its working, but it cant get the data from the net.
What i do then is, i switch off mobile-broadband and switch it on again and then it will work for some time.
But it can be very annoying and i still use my good ol z1c as my main phone, so it would be cool to fix this.
Its not the provider. No problem with that SIM-Card in other phones. Its stock-android 5.1.1
If you have an idea, please help

I have the same problem. Tried to install different ROM`s but it seems that phone connectivity is gone. It is not able to connect to cellular network (searching connection forever) but BT and WIFI works fine as well as all other stuff. This is not an issue with location since I tried it in different places where other phones working fine and shows excelent signal.
Odd, my data connection suddenly quit yesterday as well (had the EVO series ROM loaded). I loaded on the new build from today and it worked for a few, but then stopped again.
Any ideas? I can make/receive phone calls, but the data connection is no longer responding.
nobody know ???
hmm,nobody know how to dissolve this problem or nobody care ??
just wondering what i can do with my phone - coz it is unuseless now.
As i read - i'm not only one with this troubles.
p.s. - never syncro your phone with " GoodSync " program
Taxed out i had another p4000 which would connect to data then disconnect.

Problem using Portable Hotspot after latest OTA

Hi guys
First thing my desire is unbranded and unrooted.
Ever since applying the last OTA my portable hotspot has stopped working.... I connect to a data network no problem, but when I turn on portable hotspot, I loose the data connection. I can see it trying to get the connection back but it loops for around a minute and then gives up with no errors.
My wifi has been fine since the upgrade.
Has anyone else seen this or have any ideas how to fix it???
Many thanks
David
I'm not sure this is the answer to your problem, but hey maybe it is the answer so someone else's problem
A Wifi device is either a client or a server - not both at the same time.
If you tell the phone to be a Wifi server, and it was connected to a Wifi network then that connection ceases to exist.
Next it will broadcast its own Wifi network for other devices to use. Those devices (and your phone) can then browse the web, send mail etc. using your 2G/3G connection, and they can talk to one another using local ip addresses handed out by the phone.
I hope this cleared things up, if not for you then maybe for someone else
Yup - experiencing an issue whenever I select "Press to turn on".. doesn't seem to do much of anything (beyond the Processing dialogue).. and while I get the Icon in the Notification bar there is no hotspot available. Can't configure it either..
similar specs on the phone... unbranded / unrooted

Data connection keeps randomly not working?

It seems random when the data connection works and the internet works on my phone. I'll sit there with full 3G signal and i get "cannot find the DNS Server" error when trying to load webpages :S
is this a problem with my Samsung Omnia 7, Windows Phone 7 or my network (Orange UK)?
I have this problem on my HD7 as well. If I have a 3G connection, it doesn't work. It only works on H (HSDPA).
Funnily enough, I had the same issue with my HD2 running WM6.5, which makes me wonder if WP7 is using the same comms drivers.
I have this problem too! A LOT everyday in diferent locations.
Actually how can I enable the HSDPA on my HD7? Because I can only get 3G.
These are just network errors.
I use internet alot and it happens on every device I had.
My WP7 is actually pretty stable in this regard.
Same! Never works on 3g only ever H you sure its just network errors cause it happens alot
YES this is a major problem for me with my Omnia 7, I even got a replacement phone from my carrier (Optus Australia) because of it... and it's exactly the same. It's extremely frustrating and makes the phone damn near unusable. Happens on every device? what a load of rubbish, if I put the SIM in my old iPhone 3GS it works FLAWLESSLY. I don't know what I'm going to do.

Can you explain then, how come a reboot always fixes the problem?

Yep, I have the same problem with my Omnia 7.
On all 3 of the networks i've used it on, T-Mobile, Virgin and GiffGaff.
Only solution is to reboot the phone.
I thing i've noticed, is it seems to happen when I move from an area where I have WiFi access (Home/Work/Cafe) to an area where i'm using a Phone network ?
I think we can only hope that the upcoming WP7 update fixes this. Also it seems enabling airplane mode then disabling it also fixes it in a similar way to rebooting the phone.

I'll make a note of that, cheers!
Im having the same issue with my HD7. Only EVER works on H. Not on G or 3G. It's driving me insane. The exact same sim on the same provider never had an issue on my Touch Pro 2, but this phone is shocking for internet
I get this occasionally on my HD7. Not really an issue right now. It does get annoying sometimes when the wifi in my house isnt strong enough to connect

You do realize that phones switch to H only while they are actively swapping data, then fall back to 3G while dormant, to save battery?
Try it - leave your phone alone for a bit and it will switch from H to 3G. Now access something on the net and it will switch to H (if possible) to get the data, then after a few seconds of inaction it will switch back to 3G.
So yes, it is correct that it only ever works on H!
Mind you, it would be nice if it worked on G too, I'm sure it should but mine never does.
hm i thought the " H " means that i dont get 3G signal.
but i think i had the same problem!
solution:
you only need to turn OFF WIFI
somehow its not using 3G when wifi networks are close,
even if you not connected to one.
turn OFF wifi or maybe only "discover new networks"
turning OFF wifi always brings me 3G back ...
Just to add my experience here...
I have a Samsung Omnia 7 and had never experienced any issues with 3G/H data/internet issues on the 3 network in the UK.
However, I've come over to Australia to visit the folks and have put in a Virgin SIM, now I really struggle with this. The connection just isn't working even with full 3G signal.
As pointed out, toggling my Airplane Mode works most of the time - I guess this is because the phone re-registers itself with the network when you enable>disable airplane mode (just like it would if you rebooted it). Curiously toggling the data connection option seems to have no effect.
Pain in the a*se.
I had connectivity issues with my Samsung Omnia 7. I worked out that my phone was not playing nice with my router and so my wifi connected but didn't actually work.
Also, I found that 3G performance was sub-par and many apps timed out because they were taking so long to get connection.
I solved these problems by flashing a new firmware. It was a little tricky and it is potentially risky, but a quick google will lead you to the relevant information.
I used a European firmware (I am in Australia on Optus), but it works fine. I just had to change all the language settings.
Now my phone's 3G and WiFi connections both work a lot faster (no more waiting for an eternity for the marketplace to open for example).
I have the same problem and read on create.msdn.com it has something to do with how wp7 handles the connections.
If the provider cuts off the connection frequently it loses its 3g signal or something like that. Thats why my push notifications are just unreliable. If I take my sim out and use wifi only. It just works and keeps working as soon as I connect to wifi. When 3g comes into play and the carrier cuts me off because im not actively using, the phone struggles to recconect for push etc.

[Q] portable wifi hotspot disables 3G ?

had the phone over a year now, never had an issue before.
As soon as you turn on the portable wifi hotspot, i loose the 3g/h symbol from the top of the screen and from that no data conectivity?
and as sopon as you turn the wifi hotspot off, it regains an internet conection
Any ideas, ive not installed any apps recently, as far as i can remember?
Do you get an internet connection when another device connects to your phone's wifi hotspot.
If you are able to connect, then it must be working, as it's the 3G signal that the phone uses to connect the wifi to the internet. It might remove the icon, but if you can connect then it's fine.
nope, can conect my ipad to the DHDs hotspot but no internet.
the same for when i turn the hotspot on, cant brouse anything on the phone as no data conection
still not sorted this, anyone else got a aide or something to sort this?
First post (longtime lurker)
I've got the same problem here although this has only started happening in the last couple of days. The phone's data connection is fine until you enable the wifi hotspot at which point the connection is dropped to the phone, connecting any devices to the phone is fine, they get an IP address and can ping the phone directly, but beyond the phone there's nothing.
Rebooting the phone does not help.
The only app I've installed recently is Google Shopper.
Out of curiosity Fil what ROM are you using? I'm on RCMix3d Runny 3.0 which is based on Android 2.3.5 and Sense 3.5. I'm looking at switching to an ICS build pretty soon.
It also looks like we're on the same network although I think that's just coincidence.
yep sounds exactly the same issue,
as for rom, still on t-mobiles original 2.50.110.5 Adroid 2.3.3
was thinking of flashing something custom to see if it solved the problem
I've just flashed IceColdSandwich today at work (it's been a slow day!) and you'll be pleased to know that wireless tethering is working again. I'm on the train home as I type this. It's possibly something in the 2.3 image? I can't really say since we both had different ROMs (mine was a Sensation port). It could just be a bad bit of code in the gingerbread OS that produces this bug on rare occasions.
It may have something to do with the fact that T-Mobile and Orange allow you to roam on eachother's networks. Do you have roaming enabled?
To be honest I'm just stabbing wildly at possible causes here and a flash fixed it anyway. I went ICS but I don't think you'd have to go that extreme but flashing a new ROM overwrites whatever it is that caused this in the first place.
I'm just hoping it's fixed in ICS and won't happen again!
cheers, enabled data roaming, and it now works!
Since the issue, my batterys turned to crap! guessing thats the cause constantly jumping networks, and also data speeds have been very poor lately, was ok when just t-mobile, but orange is poor!
Off to the t-mobile foeums to see if its just me, or others!

Strange WIFI Issue with my router

Hey folks,
I hope somebody can help me. I have a very strange issue with my Sony Xperia XZ2 compact and my Wifi. It won't connect under any circumstances. It says "Establishing connection" but nothing happens. It worked in the first place but since two weeks, it stopped working.
What I tried yet: -
resetted the phone to default and updated to newest android
- resetted the router to default
- changed the wifi channel and Name/Password
The strange thing is: The phone connects to every other wifi, except my home wifi. And every other phone does connect to my home wifi. It seems to be a issue between my home router and my phone. But I have no clue what else I should do.
This really sucks. I really need Wifi at home.
Thank you for your help!
well,i cant turn on the wifi option now
and it will reboot randomly as i try to turn on wifi
even i could turn on wifi still there is no signal and unable to connect to everything
BUT MY LTE WORKS VERY WELL
4G SIGNAL IS STRONG AS FXXK
Bump, seeing a similar issue with my mother's phone. Wifi works at phone for her, but not at work.
