IPad 2 - Problem with 3G connection

Hi,
I'm italian user.
I have iPad 2 wi-fi + 3G. When I turn-on 3G connection it's impossible to connect on internet.
If I cancel and rewrite APN the connection start again. But it's impossible to do this every time.... My firmware is 4.3.1 and I already restored.... Solutions????

I have the same problem (well, similar). UK iPad 2 32Gb Wifi+3G.
Normally I have the 3G turned off unless I need it as when i'm at home it uses Wifi.
However, if I disable Wifi and then enable 3G, although the 3G comes up, the IP connection doesn't. I have to restart the iPad with the wifi disabled and 3G enabled to get the 3G to work.
I would suggest the issue is with their implementation of the IP stack and it not clearing out routes properly (or letting go of DHCP possibly) if you enable Cellular data whilst the iPad is on. The IP stack doesn't seem to be routing out through the 3G in that case and therefore nothing thinks it can see the Internet?
The only way we can conclusively test that is for someone to jailbreak the device to get to the command line and take a snapshot of the routing tables for each configuration. That will show where the error is.
But the simple answer is you're not alone, and it'll need Apple to fix it (it can't be carrier specific as I'm on Orange Uk and you're not!)

I have an Ipad mini with IOS7. A few days ago I began to have problems with wifi connectivity. I can connect to wifi with Google but cannot navigate in Safari nor any of my aps are able to acess wifi. Very strange. Not sure what to do!

Hi ..
Reset the device:
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
If that doesn't help, tap Settings > General > Reset > Reset All Settings
If that doesn't help, tap Settings > General > Reset > Reset Network Settings
You may have to re enter your Wi-Fi password.
If nothing above has helped, try here > iOS: Troubleshooting Wi-Fi networks and connections

Since upgrade to ios6 l have been having problem with wifi connection and connecting to App Store and iTunes store

Q since upgrade to iOS6 l have been having problem with wifi connection and getting into App Store and itunes

Saw this on another post.
Applecare Senior Advisor Txx Bxxx (I have his contact info in an email he just sent) just confirmed with me that the problem people are having with the App Store not loading is an apple issue with there servers, ITS NOT YOUR IPAD so don't go restoring it! It's not happening to everyone however but they are looking into it, its really hit or miss.

Try this first - Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
This works for some users. Not sure why.
Go to Settings>General>Date and Time> Set Automatically>Off. Set the date ahead by about a year.Then see if you can connect to the store.

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Problem with JCo Connection Pool

Hi,
I have a problem with using an RFC Model in my WebApplication. So sometimes the access to the function block works, and sometimes it doesn't work. Now I know, that there is a problem with the connection pool. Look at this message:
com.sap.mw.jco.JCO$Exception: (106) JCO_ERROR_RESOURCE: Connection pool WD_X24_MODELDATA_DEST_CPIC_REKTO_DE_useDefinedUser is exhausted. The current pool size limit (max connections) is 10 connections.
So it looks like a problem with closing the JCo Connections after using. Do know where the problem is? Because I'm using many other function blocks with no problems.

Hello,
You need to increase the pool size via Visual Administrator.
Server 0 -> Services -> JCO RFC Connections.
Change the pool size from there. I believe a restart is in order.
Regards,
Jan

Every time I try and update my iphone 4 to ios 7.1 in iTunes 11.1.5 it says "connection reset" even when there is no problem with my connection

I have an iPhone 4. I use iTunes 11.1.5 on my Mac. I am trying to update to ios 7.1 through iTunes, but every time I do that, I get a "connection reset" error, even when I know there has been no problem with my connection.
The exact error message is as follows:
"There was a problem downloading the software for the iPhone "Anne's iPhone". The network connection was reset.
Make sure your network settings are correct and your network connection is active, or try again later."
I have checked several times. There is no problem with the connection, and I have tried to download the software several times today.
Any help you can give me would be appreciated.

Just managed to successfully download the update, having retried five or six times. I did unplug my phone while the download was taking place (had asked iTunes to download only, not to update) -- suspect this had no bearing on it whatsoever, and that persistence is the only way here.

Problems with Document Connect

I have a problem with Document Connect. I am unable access office live workspace.
I have been on the help line with microsoft but they were unable to help.
Then I went to an apple store and was informed by one of the sales assistance that Document Connect never worked with the apple. Well what was the point in having it then?

I wish I knew what Document Connect is. I'd bet I could fix it. Not really, but what is it?

There is a problem with this connection's security certificate The remote computer cannot be authenticated due to problems with its security certificate. Security certificate problems might indicate an attempt to fool you or intercept any data you send

Hi,
I have this Windows 2008 R2 on which I installed remoteapp some years ago.
Now the certificate expired and I get the message
"There is a problem with this connection's security certificate
The remote computer cannot be authenticated due to problems with its security certificate.
Security certificate problems might indicate an attempt to fool you or intercept any data you send to the remote computer."
How should I renew the certificate? I already went to certification store and tried to renew certificate with same key but then it says "the request contains nor certificate template information".
Please advise.

Does the computer account have Enroll permission to the certificate template?
From the Server running your CA, run mmc, click File then Add/Remove Snap-in...
Add Certificate Templates and click OK.
Find the certificate template, then right click and select properties. On my CA its call ed RemoteDesktopComputers but might be called something different depending on what what template your certificate is based on.
On the security tab, click Oblect types, check Computers then OK. Enter the Computername and click OK. Then give your computer account Enroll permisssion.

Problem with database connectivity

Hi guys,
I'm having a problem with database connectivity . I'm using the mySQL database & org.gjt.mm.mysql driver.
I've kept the org folder under the directory where the Database.java program is residing .
My program is as follows:
import java.sql.*;
public class Database
     Connection con;
     public void connect()
          System.out.println("In connect.");
     public Connection connectDB(String username,String password,String database)
          try
               Class.forName("org.gjt.mm.mysql.jdbc.Driver");
               String url="jdbc:mysql:"+database;
               con=DriverManager.getConnection(url,username,password);
          catch(SQLException e)
               System.out.println("SQL Exception caught:"+e);
          catch(Exception e)
               System.out.println("Exception e caught:"+e);
          return con;
     public static void main(String args[])
          try
          Connection c;
          Database db=new Database();
          c=db.connectDB("root","","//192.168.0.2/squid");
          System.out.println("Connection created.");
          c.close();
          catch(Exception e)
               System.out.println("Exception caught:"+e);
It gets compiled but gives the following error when run.
Exception e caught:java.lang.ClassNotFoundException: org.gjt.mm.mysql.jdbc.Driver
Connection created.
Exception caught:java.lang.NullPointerException
I don't know why the class is not found.Pl . help me rectify my mistake.Is there any other path to be set?
Thanks.

You need to run it with the JDBC driver in the classpath
java -classpath .;[mySqlJdbcDriver.jar] Database

I have problem with Access Connections on L412 after that utilyty upgrade

I have problem with Access Connections on L412 after that utilyty upgrade in early August. Windows 7 Ultimate/x64.
It stops connecting to WPA2 Enterprise (AES-CCMP), Microsoft PEAP, no server cert, with any credentials I try to use. The same account(s) works with native Intel manager on other notebooks and on mobile devices. I lost the wireless connectivity to enterprise WiFi network.
And, after deinstallation of Access Connections, the inability to connect keeped intact with native Win7 WiFi management.
I think, something was broken in Access Connections 5.83 Build 83C753WW and some registry settings/ dll modules were altered but not returned to normal after deinstall.

Access Connections is definitely broken for WPA encryption. Both versions 5.02 and 5.84 fail for me. If I use the Windows XP wireless configuration instead of Access Connections, everything works.
Does anyone know how to report this to Lenovo? I chased links around the web site but couldn't find a place.

Problem with Internet connection sharing between eMac and Powerbook G3

Hi,
I seem to be having a slight problem with internet connection sharing.
My eMac is the main machine with the internet connection, and its running 10.4.6, the Powerbook G3 is running 10.2.8.
I can connect them all up and get online with both, but I the problem I am having is when I turn the Firewall on on the eMac, the powerbook can't connect.
Is there anyway I can keep the Firewall enabled and still use internet connection sharing?

How do I know which ports the Powerbook is using?
Also I had web sharing enabled on the eMac and it made no difference at all.
Plus I don't know if this means anything to you, trying to decipher it myself, all I can make out myself on there is port 80.
