Blackberry Curve Drop Network After Turning It On

I have a blackberry curve with AT&T, recently it has started turning off the mobile network by itself. I use the on/Off function to turn it off, have not changed any of the settings that I know of, yet the following happens. I turn it on the for first time in the day, it gathers itself, collects emails, VM, etc., then it shows OFF in the mobile network. I go to network connections and sure enough, the mobile network is off. I turn it back on, and Ta-Da, it's back, and stays that way until I turn it Off/On again.It only seems to happen during the first "start-up" of the day. I do not use stand-by, or auto on-off, just the red "end call - On/Off Key" Any help would be appreciated. Thanks.

Convenience Keys are set to the defaults, Camera and Push to talk. It seems to happen right after I initially turn it on for the day, it gets my emails, shows voice mails, etc. Then it shuts off the mobile network. I go to make a call, and it prompts to restore connections. I either follow that prompt or have to go to the network page and turn on the mobile network from there. Sometimes it drops the network after a phone call as well. Finish a call, go to make another one and Bamm! the network is off again. Not sure what is causing this, and is fairly annoying, curve is only a few months old, and was new, not reconditioned at the time of purchase. Thanks.

Blackberry Curve 8520 won't turn on or charge

My blackberry curve 8520 will not turn on,there was a red light on for a minute! Took out my sim card,memory card & battery and tried to charge it then. It came up for literally one second a drained battery sign. Really don't want to send it away, any help would be great Thanks!

Leave the device to charge 2-3 hours, and then, still connected to the charging cable, remove the the battery from the device a few seconds and reinsert it. If it boots--leave it to charge to 100% (check Options > Status for the percentage). If it doesn't reboot on the first attempt, leave it several more hours. I've had one charge for two days before it came back to life after an extreme battery depletion. Every 3-4 hours, with the device still connected to the charger, you can remove and replace the battery to see if it reboots.

My blackberry curve 8520 is not turning on it shows a red light

My blackberry curve 8520 will not turn on it shows a red light flashes 2x then my keypad lights an thats it nuthing else happens please help me i havent got a usb cable so cant use blackberry desktop manager

Hello Hasanm52,
Welcome to the community!
Seems OS is corrupt, so you have to arrange a USB cable to connect your devci with the pc.
Procedure to install OS:
1.) Download and install blackberry device software of Blackberry 8520 from www.blackberry.com.
2.) Install it in your PC & connect your device with PC.
3.) Access path c:\prog. files\Common files\ Reasearch in motion\ App loader\ now dowble click on loader.exe
4.) Further procedure i very user friendly, so please follow steps (may take approx 90 mins).
5.) In between, it will prompt you to take backup as well, so do take care while clik next or continue.
Good luck..!!!
Before doing above activity you may try
By pulling out battery & connect device with charger without inserting battery & wait for 5 to 10 mins.
Itwill prompt you a no battery sign on your handheld, once you get the sign on your handheld, insert battery without un plugging charger 7 wait for another 5 to 10 mins. Hope this will work for you....
otherwise you have to perform the first procedure, i mentioned...
Thanks....!!

Blackberry Curve dropped in tea

I have dropped my Blackberry Curve 9300 in my cup of tea and I have dried it out with rice and it turns on fine but my keyboard is been messed up. Every key does the wrong letters or not what they are suppose to. Is there anyway I can reset my phone to stop this happening or doing anything else?

Hi liamkavfc
When our device get wet we had to follow certain rules like never try to turn it on unless you are sure that the device is completely dry and yes I must say you are lucky if you are able to repair that device at that much cost. Have a look at this Article : Got Your BlackBerry Wet?
Yes you can try repairing your device but Updrade is a good choice .I wish you good luck.

Blackberry Curve 8520 will not turn on!

Hello, I am desperately hoping someone can assist me with the problem I am experiencing with my Curve 8520.
I have spent ages online looking at other forums and trying to see if people have had the same issue as me and to see if anyone had worked out what the problem was and could resolve it. It appears as though I'm the only one having this exact issue!
Yesterday, my phone turned off, without me using the off button. It was sat beside me, untouched but when I went to check it, it had turned off. I believe this has happened before and was not an issue, so didn't panic. However, when I tried to turn on the device, it would not work.
Whenever I attempt to turn it on the red light shows for a while, before it attempts to switch on (loading bar screen shows). It looks as though it is about to work sometimes, but gets to the same point, which is probably about 5% complete and then goes dead again. It continues to try to switch itself on without my command.
I have tried charging it, leaving the battery out for a while and trying again etc etc but to no avail.
It's such a shame because I was looking to splash out on a new model (as this now, it quite a low grade of BB!) but after this issue I am not so sure. Reading forum posts from other users whilst attempting to find a remedy for my issue has only out more doubt in my mind about using BB again. I sincerely hope my faith can be restored.
Please let me know if I missed any information which would be helpful, I am not very 'techy' at all.
Thank you.

Hi and Welcome to the Community!
Please try this sequence...note that, throughout the entire 4h15m process, your BB must remain connected to a known-good wall charger (not PC USB):
With the battery inside, connect your BB to the wall charger
Leave it alone for 2 hours, no matter what the LED or the display does
Remove the battery
Wait 15 minutes
Insert the battery
Wait another 2 hours, no matter what the LED or the display does
This has been known to "kick start" some BBs.
It is also possible that your battery or BB has experienced a problem...to test, this sequence is needed:
Obtain a known good and already fully charged additional battery...use it in your BB and see what happens
Obtain access to a known good and identical BB...use your battery in it and see what happens
The results of this will indicate if it's your BB or your battery that has the problem.
Good luck and let us know!

My iMac (Mac os X Lion 10.7.5) does not connect to known Wi-Fi networks after turning it on or waking it up?

I've tried downloading this sowftware update but it says it needs version 10.7.3
Nothing seems to work, Please help.

Test after taking each of the following steps. Back up all data before making any changes.
1. Make sure the network is on the preferred list by following these instructions. It's important to read the article carefully, as it's the starting point for any further efforts to solve the problem. If you skip any of the steps, the problem may not be solved.
2. Follow the instructions in this support article under the heading "Symptom: The network connection drops unexpectedly."
3. Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
4. From the Location menu at the top of the Network preference pane, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
5. Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
6. In some cases, the problem has been resolved by repairing permissions on the startup volume.
7. Reinstall OS X.

Brand New Mac Mini drops network after a few minutes

My new Mac Mini (Core Duo) arrived a couple of days back and I couldn't wait to set it up. The next thing I did was to download all the latest updates but the network connection kept dropping after a few minutes (seemingly randomly). This is the wired connection (not airport) and all other computers on the network are working fine.
I thought it might have been a problem with the updates site but now I'm trying to copy my data across the network from my old Windows XP PC (I want to switch) and the connection hangs again after a few minutes.
The only way to get the network back up is to reboot the system, then it works okay for a few more minutes. I've changed the Ethernet cable and the other PCs are working fine - it's just the Mac that has issues.
I wondered if the network card is faulty but does anyone have any other ideas?
I guess as this is only a few days old Apple might exchange it?

Mac Mini Core Duo Mac OS X (10.4.7)

Hi John,
My ISP is PlusNet and there are 2 Windows XP PCs, a Windows 2003 Server, 2 Windows 2003 virtual servers, an HP printer, a DLink Wireless Access Point and a Linksys NSLU2 NAS box all working perfectly happily here - the Mac is the only machine that doesn't want to play.
The router only has a single Ethernet port so that's connected to a Netgear 10/100Mbps hub which the other devices use.
In addition it's all NATted so the ISP could only block my external IP address - they don't have access to the router config and in any case all the other devices are communicating with the Internet over the ADSL link with no problems so I think I can rule out the ISP doing anything nasty.
Thanks for the suggestion anyway.
So... here's the progress to date:
I spent two hours on the phone to Apple Support at national rate phone charges. I finally snapped when they asked me to check the firewall settings on my Windows PC (I pointed out that if there was a firewall issue then no data would copy - not several hundred megabytes before timing out). They suggested I took the Mac to an AppleCare centre for diagnosis to see if it could copy files from another Mac (so much for interoperability - they only care that it works with Macs).
I have confirmed that the problem exists on both static IP and DHCP configurations, and whether or not I set the duplex manually or automatically on the network connection. Interestingly it only occurs connected to a 100Mbps/half duplex hub (not a 10/half hub or a 100/full switch or a 100/full crossover cable) but as all the other devices are working fine I can rule out issues withe the hub.
So, now I have the Mac connected to a 100Mbps/full duplex switch, with no other devices connected. That switch has a link to the hub with the other devices connected and on to my ADSL router.
Everything seems to be working but obviously it's not an ideal situation as the Mac should work on the same Ethernet hub as everything else.
Thanks to everyone for their suggestions. If anyone has any further ideas I'd love to hear from you.
Cheers, Mark

310N PC drops IP after turning on laptop

Have a 310N and my pc will loose it's lan connection shortly after I turn on my laptop. I have to power everything down and back up for my pc to renew its IP but as soon as i turn my laptop on it bumps my PC off. I'm using DHCP and have a large enough address pool. Any ideas?

If your PC is Connected to the Router, its better you give a static ip to you PC. Providing Static IP on computer:
Click on the Start button >>> Settings >>> Control Panel >>>Network
Connections- Right click on the icon for Local area connection and go to properties- On the 'General' tab select 'Internet Protocol TCP/IP' and click on the Properties button- Select 'Use the following IP address'- Provide IP Address - Eg: 192.168.1.5 Subnet Mask - 255.255.255.0 Default Gateway - 192.168.1.1- Preferred DNS 192.168.1.1 Alternate DNS - 4.2.2.2 >>Click on Ok button to Save and Click on "Close" on main Properties window. This will solve your problem.

Syncing Blackberry Curve 9370

I can't turn off wireless syncing on my Curve 9370 so that I can sync using the Blackberry Desktop software. The directions given suggest going to the Calendar application and/or Contacts application on my phone and "press the Menu key then Options and then change the Wireless Synchronization field to No." But, that is not one of the options in either of the applications.

Hi marktiscareno,
In Calendar or Contacts on your BlackBerry® Curve™ 9370 smartphone, after pressing Menu key and Options, you should be able to see your calendars / address books in a list on the options screen.
Once you click on each calendar or address book in the list to open it and display the properties, you should be able to see a Wireless Sychronization checkbox for any calendar or address book that has had wireless synchronization enabled. This article should provide more information. http://bbry.lv/nmp2dM
Hope this is helpful.

BlackBerry Curve 8330 with Sprint and OS 4.5?

I just got an email this afternoon from RIM saying, amongst other things, that the BlackBerry OS 4.5 was available for my phone. After following the link on my laptop, it gave a list of supported devices (including ALL BlackBerry Curve revisions) and, after clicking Update, it installed the software to my computer, only to say my device was not supported.
Why would it email me saying it's supported, and list my device as being supported, but not work?
Also, I've seen a bunch of "unofficial" or carrier-specific 4.5 versions (Vodafone, Australia, etc) but was kind've hoping for an official update from Sprint or RIM, as opposed to downloading a version that may or may not work on/brick my device.

I don't think it is officially released for ATT or Sprint - Others will let you know if I am incorrect.
I have verizon and uplated a few weeks ago and love it.
