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] DATA connectivity problem with ARC

hi people
i'm noticing a problem with my data/edge/3g connection.
it simply stops working at times .. it just shows data being sent but no data received and my internet doesnt work.
This becomes fine after a reboot but again has a problem after a few hours
Is anyone else facing this problem too with Data connectivity ?

Yes, same problem with my german arc.

I am not facing any problem with data connectivity

same problems here, I found that stopping the WIFI and re enabling it is enough to get it back on track but its still a serious issue.
I don't like finding out I am missing e-mails an hour too late.

I only found it happens when I switch from 2G to 3G with data on.
So my work around is to turn data off first before switching between 2G <-> 3G. After that, turn back the data on.

This only happens to me on WIFI, on 3g everything is fine.
I am thinking about flashing the UK build to see if it helps.

I used to have the same problem with my x10. Data just stopped working randomly. I used to have a widget to turn 3g on/off and when the data stopped working, so did the widget. Was strange, and only a reboot solved it.

I have wifi problems,it sleeps after a while,no sleep is selectet.

i have wifi problem, at first it disconnects by itself and now much worse, my arc could not even identify or scan my wifi at home. Anyone also have this issue? or anyone know what to do.

same here. wifi works fine. til awhile later (evactly how long i didn't notice. will keep track)
After which no matter how i turn off & on wifi, forget the network & re-enter p/w. even off & on my phone. wifi status "connecting.... disconnected....connecting.... disconnected." will drains off a lot of battery if go unnotice.
i found a cumbersome work around... off the arc wifi & reboot modem/router. then can "obtaining ip address". but thing is, all other devices works fine.
so is it arc's fault? since all others can connect to wifi except arc
or
router's fault? i wasn't doing / changing setting on the arc. just reboot router. but wouldn't it be silly to do this everytime i use wifi on the arc?

so still no fix? sometimes it happens to me a few times during an hour...

Guys maybe this will help you out..
Go to wifi settings, press menu button->select advanced->under wifi sleep policy, set as never sleep
If not set the wifi shuts down to save battery.
And wifi is given more priority over 3g or 2g connectivity, so if you have wifi on you may not have proper connectivity to 2g or 3g

Turn on/off airplane mode, if you can't get a data connection. In a german forum some guys discussed about issues with multi-sim-cards, but I guess it is software related.

i changed my number and sim a couple of days back. with the same provider. my arc after being out of signal cant reconnect to the data network. the phone calls work fine. but the data is giving me problems. im still confused as to why this is happening. whenever i activate and deactivate the airplane mode, data connection comes back alive. could it be a problem with my sim or the phone radio?
edit: oh and i also reflashed my phone via sony ericsson update service, the problems still there.

Same problem here. This is really frustrating.

I dialed *#*#4636#*#* then phone info and pressed menu. Then I selected enable data connection (was disabled previously). The data didnt enable then. I went to settings>mobile network and enabled data from there too. Ever since, no disconnections. I dont know if this procedure or the fact that I tried to seat my sim properly worked, but u may try either. Let me know if this works....
Edit2: the above doesnt work.

I inserted my old fat sim and recreated the situation, the data automatically reconnected. The newer sim that's a microsim is causing the problem.

Network loss

Ok guys, having a real problem here. Often when I am connected to either 3g or wifi my phone will stop picking up signal suddenly. AIt's almost every time and I will have to disconnect from the network manually and reconnect and it will instantly pick up signal again for a while then it'll repeat. When it suddenly stops it doesn't show on the status bar that I have lost any signal. With 3g its kinda just at a stand still not receiving or uploading and with wifi it just stays the same but I'm still not picking up a signal because by web pages won't load neither will other apps that require network load until I manully disconnect and reconnect. Is anyone else having a problem like this? I don't think it was like this when I firs got my phone a month ago. I'm at a loss. Any help is much appreciated. Oh I'm completely stock btw haven't rooted........(yet) lol

It has happened to me a couple times that I have noticed. I will be streaming music and walking and all of a sudden, nothing.
Even a soft reboot does not help. It will require a full reboot generally to solve the issue. I have not been able to identify the issue specifically. I suspect it might be related to LTE testing in my area.
What's the LTE status in your area?

No lte yet but as I stated earlier it happens on wifi too. It'll still show that the signal is connected but my pages want load at all after it happens and when I try to refresh it'll say that the webpage could not load because there is no network. Only until I manually shut off 3g or wifi in the settings and turn it back on will it pick up signal again but only for about 5 minutes. This has happened in various locations on 3g and wifi and will even happen at home wifi.

This has happened to me as well... A lot . Stock.. on various roms.. No lte as well.. But it's in the works
-TeaM VeNuM Like A Boss
-Galaxy Note II Edition

I've had this problem too. Sprint replaced my phone and it never happened again.

I think reactivating hands free actually fixed my problem...for now anyway. It's not losing network like it was before. All I did was enter on the phone dial pad ##72786# that'll reactivate. Hope this helps
