Problems with HTTP connections in 7.0

Hi all

HTTP connections in my work of fine application with 5.0 and 6.0, but they do not work with 7.0. Enough actually, they work with 7.0 when the device is connected with WiFi, but not with 3G (Sprint) mobile network. Connections are also running smoothly on the Simulator. When the application tries to perform an HTTP request, it seems to open the connection, but the connection hangs just until it expires in a minute later.

I'm unable to debug applications with the SDK 6.0 and 7.0 in Eclipse. The debug mode is always suspended my environment.

Can someone speculate as to why this might be the case? For added convenience, my code is below:

public class HttpRequest extends Thread {
    private String method; // GET or POST
    private RequestResults screen;
    private String url;
    private Loader loader;

    public HttpRequest(String url, String method, RequestResults screen) {
        this.url = url;
        this.method = method;
        this.screen = screen;
    }

    private void connection() {
        // The following code will only build under JDE 4.5 and later
        ByteArrayOutputStream out = null;
        HttpConnection conn = null;
        InputStream in = null;

        try {

            conn = (HttpConnection) Connector.open(url
                    + ConnectionParams.getConnection());
            conn.setRequestMethod(method);

            int responseCode = conn.getResponseCode();

            // Check for both 200 AND 201
            if (responseCode != 200 && responseCode != 201) {

                loader.stop();

                Notify.inform(Constants.CONNECTION_LOST);

                conn.close();
                return;
            }

            out = new ByteArrayOutputStream();

            in = conn.openInputStream();
            byte[] buffer = new byte[20000];
            int bytesRead = 0;
            while ((bytesRead = in.read(buffer)) > 0) {
                out.write(buffer, 0, bytesRead);
            }

            screen.requestSucceeded(new String(out.toByteArray()));
            loader.stop();

        } catch (IOException ex) {

                } catch (IOException e) {
                }
            }
            if (conn != null) {
                try {
                    conn.close();
                } catch (IOException e) {

    }

    private static ServiceRecord getWAP2ServiceRecord() {
        ServiceBook sb = ServiceBook.getSB();
        ServiceRecord[] records = sb.getRecords();

        for (int i = 0; i < records.length; i++) {
            String cid = records[i].getCid().toLowerCase();
            String uid = records[i].getUid().toLowerCase();

            }
        }

        return null;
    }
}

The culprit seems to be adding the line

ConnectionUID = record.getUid ();

for my URL when you set the connection settings:

if (record != null && (coverageStatus & CoverageInfo.COVERAGE_DIRECT) == CoverageInfo.COVERAGE_DIRECT) {
// Have network coverage and a WAP 2.0 service book record
    connectionParameters = ";ConnectionTimeout=10000;deviceside=true;ConnectionUID="
    + record.getUid();
}

Once I have remove this, it works fine...

Sierra Siri, «I have some problems with the connection...» »

Guys,

I just installed Sierra on my MacBook Pro (retina, 13 inches, early 2015) version 10.12. I can't get Siri at work, the app tracks, he hears what I'm saying, but after awhile, he returns with two messages, both on the screen and verbally "I have some problems with the internet connection. Please try again in a moment. "&"Sorry, I'm having problems with the connection. Please try again in a moment. »

Any ideas?

Thank you

It's a network problem.

Check the proxy settings that blocks maybe, or a firewall.

Something there?

Siri does not (problems with the connection)

Hello

I installed macOS Sierra yesterday. Everything seems to work fine, except Siri. With Siri I always get an error message "I am having some problems with the connection. Please try again in a moment. ». But this seems to appear every time. The network connection works fine, I can't access the Internet without problem.

No idea how solve the problem?

I use an iMac (27 inch, mid-2011). Internal microphone is connected, I also see the 'waves' change while I am speaking.

Concerning

Thomas

Hey, thochstrasser. Thank you for using communities of Apple Support.

It seems that Siri is reluctant to make his debut on your iMac after upgrade to Mac OS Sierra. I want to make sure that you get the benefit of this new feature on a Mac.

1 try safe mode if your Mac does not start -even if your iMac to market, safe mode makes sure it starts successfully.

2. How to test a question in an another user account on your Mac - since this is most likely a software problem, test to another user will indicate if it is right to your user account or throughout your system.

3. use Time Machine to back up or restore your Mac - if it seems to be systemic, the next step should not cause problems. But it is always better "to have" a backup to the "need".

4. on OS X Recovery - the issue as part of the operating system, reinstall should do.

Have a great weekend!

Satellite C600/C660D - problems with WLAN connectivity

Hi guys

I recently bought a Toshiba Satellite C660/C660D laptop to replace my old. I set up a wireless connection at home too. According to my laptop and wireless connection that I am connected but when I go to use internet and try to search for something it won't let me. I ran the troubleshooting and Diagnostics over and over again and the message I get is "your computer seems to be correctly configured but the device or resource is unresponsive."

It is not a problem with the internet connection that I tried to plug in on my old Toshiba laptop and it works perfectly well and my sister tried it also on his Sony laptop and no connection problems.

Is there a setting that needs to be adjusted?
I would be very grateful for any assistance with this and as I don't know what else to do. its starting to get a bit frustrating now

Thank you

It's very strange.
Have you noticed the same thing using different browsers?
You can use any other application like Skype or MSN?

What you can try is to update WLAN driver.

Please visit Toshiba s WLAN portal and install the latest driver for your WLAN card - http://aps2.toshiba-tro.de/wlan/

Problem with internet connection Wi - Fi Windows XP - very 'slow' packages

Hi people, this problem has been driving me crazy for weeks, so I wonder if someone can provide a solution! Sorry for the long post, but I tried to put in as much information as possible.

In short, I decided to rebuild an old laptop in Windows XP (2006) I (latest updates installed). I'm without audio (cannot find drivers), but this isn't so much a problem. The problem needs to connect to the WiFi.

The internal WiFi card is an Intel (r) PRO/Wireless 2200BG (or, at least, it's the driver).

WiFi is displayed as 'Connected' and ' Signal strength: Excellent "(as my laptop is sitting right next to the hub). Ethernet (wired) connection to the hub works perfectly. I have WiFi BT working connects perfectly with my Mac and my iPod, I know that there is absolutely no problem with the router.

However, my laptop does not seem to want to connect WiFi, despite 'positive' messages above. All browsers (IE, Chrome, Firefox) display a message stating that they cannot connect to the internet. Nothing in browsers suggest that all DNS settings have been changed.

I * think * the problem might be because the packets sent/received are still very low - if either enter three digits, I have a lot of luck. For now, they are stuck on envoys = 14, received = 3.

So, what I have checked/tried is the following (all based on Google search) - none have worked:

(1) I can confirm that the automatic Wireless Configuration is enabled, started and set to automatic, and that Windows is used to set up my network.
(2) my wireless network appears in my favorite networks and is automatically connected to (or should be :-)) - I have added/removed the connection several times, check the wireless key, every time, without success.)
(3) the TCP/IP menu is configured to obtain an IP address and a DNS service automatically.
(4) type ipconfig/all at the command prompt seems to show that everything works OK:
- The physical address is: 00-16-xx-xx-xx-xx (I removed the last few digits as it is an open forum, but is probably not a security issue)
- DHCP is enabled.
- Automatic configuration is enabled.
- The IP address is 192.xxx.x.xx (as above)
- Subnet mask is 255.255.255.0
- Default gateway, DHCP and DNS server are all the 192.xxx.x.xxx (as above)
However, IP routing is NOT enabled or is Proxy WINS. Node type appears as unknown.

I tried the DNS, IP address in the command line (don't remember the command), hot flashes reset everything I can think of or have found via an internet search.

I also tried the two separate Wireless USB key (only install the drivers - now deleted), which is not working.

I am so right in thinking that everything seems OK, except the transfer of packages very low? Anyone who has any other control I can try - or better yet, a potential solution?

Thank you!

Hello c0ley,

Have you tried to change the wireless channel that your router is running at? There may be interference that could prevent the internet connection:

Take a look at step 6 in this article that give more details about it:

http://www.Microsoft.com/athome/Setup/wirelesstips.aspx

If you need assistance to change the settings of the specific router, you will need to contact your router manufacturer or your internet service provider.

Problem with Internet connection - connect only after you turn off allowing then again.

It is a recent problem that unfortunately I have very little information on. In other words, after months be happy and connection to the internet when you start the computer has decided he won't d more, instead he wants to deactivate and then activate the connection to the local network before it will connect.

There is no error message and the convenience store could not find that something wrong then directed me here! I tried to diagnose too but didn't know what was wrong either. There are two computers connected through a router and the other is fine, ISP technical support assures me it's nothing to do with them either.

It left me speechless. I tried the system restore, I crossed the two diagnoses available in internet options and I called ISP support. Although this isn't a direct threatening problem, it's one of those little niggles you want just leave.

If anyone has any ideas on how to fix things, I'd be grateful.

* Acer Revo running Win 7.

Hi tmaxwell83,

1. did you of recent changes on the computer?

2. do you have security software installed on the computer?

3. What is the type of internet connection you use?

This would happen if the NIC driver is corrupt or needs to be updated.

I suggest that you install the updated drivers for the network adapter on the computer by visiting the network card or the computer manufacturer Web site, the check if it works fine.
