Network signal recovery problem

iOS 7 does not recover network signal, after loosing at uncovered areas such as underground or elevators. It stayes at "searching..." at the network label. Everytime I make either "airplane mode" on/off or "reset network settings". Is there any solution?

I've seen this before and the issue was a faulty SIM card or poor network coverage

I haven't gotten a new sim card because the problem has been presenting itself in various cards not only mine. So far, all I've done is reset my network settings.
Last night, I turned off the 3G tab and it had all the signal bars. Today, I did the network reset and it's working apparently. But like I said before, previously the bars just disappear and the iphone only has the 3G activated.

Is there problems with the network/signal in TA3 Taunton area

Is there problems with the network/signal in the TA3 Taunton area I have not had a signal all day and then to make contact with one of my children regarding school pick up.

Unfortunately so. Spoke to EE today and the service may take up to 72 hours to get back to normal - which is unbelievable given how much we use our phones for day to day life! As they cannot do anything for us, to thank us for our patience they are asking us to monitor when the service resumes and get back to them (no doubt on their £ per min line) and let them know and they’ll credit us for the down time. Just Brilliant!!

I just upgraded my iPhone4s to iOS7 and now I am unable to make phone calls and send/receive text messages. Network signal indicator on the upper left side of the display shows hollow circles instead of full circles. Any idea how to fix the problem?

I just upgraded my iPhone4s to iOS7 and now I am unable to make phone calls and send/receive text messaes. Network signal indicator on the upper left side of the display shows hollow circles instead of full circles (but with the network provider name). I checked with my colleagues in the office who use the same network and theirs work just fine on iOS7. Any idea how to fix the problem?

I have also called my service provider and my service remains active in the network. I tried removing and reinserting my SIM but to no avail.

P1 Problem with network signal

My p1 is losing signal when is on 2G network on 3G network signal is poor, my phon with that problem is unusable

First of all, put your SIM card in another mobile and see if there is any difference in signal strength.If it works OK in a different phone, then I would suggest a software update on your phone.

Signal drop problem in Asha311 network mode is kep...

Hi All,
I just purchased new Asha 311. i just noticed one strange thing. If phone network mode is kept on "Dual mode"
I am facing signal drop problem after every incoming or outgoing call ( same the case with SMS ). when we keep network mode in "GSM" mode there is no problem at all.
is anybody facing that problem.
guys please suggest what should i do ? . is it a problem in cell phone.
Regards,
amit kushwaha
Solved!
Go to Solution.

When you select the dual mode the device will try to find the 3G connection. If the strength of 3G is adequate it will connect and when the strength falls it switches to GSM. Now if you are in an area where 3G is available but the signal strength is not that good, it will constantly switch between 3G & GSM. That leads to problem. Keeping phone in GSM mode forces it to stay that way & ensures constant connection. If you have 3G activated, then you can force the device to stay on 3G by selecting that mode. Please note that the coverage area of GSM in some places is more than 3G so you may get no signal on 3G but it may be present in GSM mode.
Please mark the post as solution if it solves your problem.

N79 network signal problem

hi guys,i have recently bought a n79 phone just a week earlier and now i am facing a probem with the device.The network signals and the operators name just disappears suddenly any time and then signals never come back till i switch it off and then switch it on.i used a samsung phone earlier with the same network operator and no such probem ever occured.

could be an old sim card if its two years old or so it might be wise to get a new one, also can you exchange your unit or go to nokia care and see if they can make some assessment as to what might be going on ?

No network signal on Xperia L

Just got an Xperia L from my network provider. I placed my sim in it but there is no network signal at all. I put my sim back in my old phone and checked for network signal and there was signal. So it's really a problem with the phone. Do I need to check the network settings? I've tried searching for available networks and the phone detects my provider. But it does not want to connect whether I choose connect automatically or choose manually. Please help. Thanks.

i have the same problem with network reception..it comes on and off but when i place my sim card in another device network reception is full all the time.whats wrong with xperia phones...i begginig to loose trust.

Newport ESP 300 error with Signal Recovery 7280 DSP

We bought a new lock-in amplifier (Signal Recovery 7280 DSP) for higher frequency to replace our older version (Signal Recovery 7265 DSP). There are not a lot need to be modified in our labview program since the commands are the same for 7280 and 7265.
But the error then came up. The ESP 300 always beeps to show there are some error. But I can not find out why.
Here is how we use these two devices:
Step 1. Computer read signal from 7280 DSP lock-in amplifier.
Step 2. Computer controls ESP 300 to move a certain step size of a linear stage.
Step 3. Determining whether linear stage finish the step motion or not (use command MD?). If yes, then go back to Step 1 (read signal for each step stage moves). If not, determine again until the motion is finished.
When I do highlight execution, I can see sometimes it took longer time for the step 3 to finish. And when this happened, ESP 300 would beep. The step size I was doing is very small so it should finish in a very short time. And, when I use Signal Recovery 7265 lock-in, never had this problem.
Need to be point out is before this loop from step 1-3. I had stage move to initial position, which normally need long time to move, where I also use the same commands for determining whether stage finished moving (MD?). And there are never errors or beeps.
So, I do not know where the problem comes from, seems it is the combination between lock-in and ESP 300.
Is there anyone can help me with this problem? Really appreciate it. I bothers me so much.
Thank you.

Hi,
Could you provide us some more details about your motion controller? Are you just using LabVIEW to control this, or do you have some NI Motion Hardware?

Signal recovery 7225 lock-in - Dumping curve buffer issue

Hi there
I am programming an experiment that requires me to take data fast using the curve buffer of my lock-in amplifier (Signal Recovery 7225). I have been using the supplied vi files in labview, but seem to be having a problem with the read buffer vi. I get a file but it only contains the names of the variables I am measuring, no data. I would be very grateful for any assistance. The vi is attached.
Thanks
Grace

Hi Guys
I fixed it! I went into the curve buffer vi and removed the select function that input the dump curve comman string. It had been selecting the dump curve as decimal values instead of the dump curve as a binary command. The labview VISA function seems to prefer binary input. The fixed it and the ammended vi is in the attached library as Read Curves from Buffer Binary Set.vi.
Hope this helps someone else too.

Signal recovery 7270 lock in

Hi
I am trying to connect a Lock In Amplifier - Manufacturer: AMATEK , Signal Recovery 7270 DSPLock In Amp.I downloaded their drivers and labview codes to check interfacing of the device.
When I run the main vi, it runs and shows no error code but the magnitude and phase data can not be read on the front panel (OUTPUT), which I expect it should read from the Lock In.
I checked the block diagram,there is a sub vi called: initialize.vi which gives an error code: -1223 , LabVIEW: Instrument identification query failed.
How do I get rid of this error. what does it mean?
Lock is connected to MAX, it shows device is running properly and also the VISA interactive control worked fine.
I am attaching the .llb file for this Lock In.
Main vi (orginal by AMATEK)is saved by file name: SR7270 Front Panel-Single Reference Mode.vi
I want to plot the Oscillator Frequency against the Osc. Amplitude but as OUTPUT is not showing a change in data, graph is also not showing any data.
Can anyone please suggest what is going wrong in the vi.

How do I get rid of VISA Error -1073807339?
Hi
This is still in continuation to the problems I am facing with the Lock In Amplifier. The codes and drivers are absolutely perfect even though they were initially designed for LV 8.2 Version.
Right now, I want a direct solution to this :
How do I get rid of VISA Error -1073807339?
When I run the SR7270 VISA Write/Read.vi , it gives this error at the VISA Read.
I am using USB for communication.

My N900 is not showing Network signal

I have been using my N900 since last 13 months everything was working fine. Suddenly it stopped showing network signal. I took it to nokia care they looked at it and I dont know what updates they did. They changed some ICs and charged me heavily but still they couldn't fix it. They assume its due to some issue in motherboard. Now my warranty has lapsed they are asking very huge amount to fix the issue. People always advised me not to buy costly nokia phones as their quality is very inferior. Nokia has really made a fool of me by selling such a substandard hardware. I should have bought Iphone atleast my money won't have gone waste.

now this can be a stupid icons problem, enable devels and install powatool and check for "connui cellular" in the statusbar options, check it and uncheck it and retry ........
and try this : install theme customizer, and the symbian-anna icon pack (or any icon pack that changes the signal bars icons) change the icons and reboot .
and finally can you type this command in x-terminal : dbus-send --system --print-reply --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.get_signal_strength | awk 'NR==3 {print "-"$2" dBm"}'
and than click enter , take a screenshot (ctrl+shift+p) and post it here .

Nokia N70 not showing network signals

Hello my dear friends,
I am currently facing a problem for my handset nokia n70.
The problem is that the network signals which we always see on the top left side of the screen is not visible.I have checked by exchanging the sim card and tried it on another handset which is working fine.So it is confirmed that the handset is having some problem.Could any body helpout to resolve my problem.
Regards,
Nitin

One thing you can try is to reset the phone using the instructions you can find in this post :
/discussions/board/message?board.id=smartphones&message.id=4007
However please be aware that doing so will wipe ALL the data from your phone such as information in your calendar, contacts and so on.
In order to save your data you can use the PC Suite application to save and restore the data from your phone - this software can be found here :
http://www.nokia.com/pcsuite
One thing to note is that as part of these diagnostics, you should NOT restore any backup or install any software on the phone as you could be putting the problem back onto the phone.
If this doesn't work then it's likely you have a hardware fault and you should approach your local Nokia Service Centre to get your phone fixed.
Hope this helps.
Please let me know how you get on.
Regards,
Edward

Lenovo P780 - very weak network signal

very low/weak signal. always no network signal even in 3G COVERAGE. SOME area can reach 1 or 2 bar signal, but other phone with same network and same place got 3G and full signal. I had install signal booster, but nothing was changed. Thanks.
Moderator Note; link to unknown direct download removed

Hi, I have the same problem as well. I bought this phone from Malaysia, from a shopping outlet (Txxxx) and I am sure that it is original set with warranty. I use 2 SIMs, since it is dual SIM, dual standy but 1 pass then I can configure 1 SIM for data plan whereas another is for call and sms. It is cheaper for me. Both of the SIMs are from the same service provider. All of the time, SIM2 will lose connection when the signal is low (rural area, office area), it become "X". Then for sure it is not service provider problem as SIM1 is OK. I guess SIM1 has higher priority than SIM2. What I have to do to enable back SIM2 by turning off SIM1 and SIM2 in Settings then turn on SIM2 then SIM1. But once I turn off SIM1 (plane/flight mode), I can see that SIM2 is back to normal. The signal bar is full. I just guess that both SIMs might be fighting resources when signal is low and SIM2 will always lose out.Hi arj99, you are using1 SIM or dual SIM as I think might want to switch back to use 1 SIM only.It would be nice if there is a solution from Lenovo on as if a phone cant make call then it is kind of stupid as this is the basic requirement of a phone.

My iPad 2 has stopped picking up mobile network signals once it moves out of a WIFI zone. Please advise

My IPad2 has stopped picking up mobile network signals once it moves out of a WIFI Zone. any possible reason?

Unbelievable.
After taking all the time to write and post that, I then switched "airplane mode" on and off again and it started picking up the 3G signal fine.
I had read a couple of threads about Ipads / Iphones "locking" onto GPRS and this being the only way to switch them back, but I DEFINITELY tried this before the IOS 7 upgrade and it didn't help.
So was it just a coincidence this time or did the upgrade make a difference? No way of telling I suppose so no help if you're reading this looking for a solution. I can only keep an eye on it and see if this becomes a regular problem......
