Klink not transferring data

[Kevin Malone]

I use Klink on an LG Volt with KitKat, Virgin Mobile, and an Acer Windows XP laptop (with WiFi radio disabled).  I uninstalled the helper application and installed the latest one, Faveset_Klink_Installer_1.11e.exe.  It works great for a minute or so, then it stops transferring data. The LTE wheel on the phone doesn't spin and the page times out or I get an error messages saying I'm not connected to the internet. 

Yet, Klink still shows connected on both ends and USB debugging is enabled. There are no error messages.  The DOS Ping command works - DNS returns IP addresses and the packets come back. The phone's browser works fine too.

All I can figure is that Virgin Mobile is throttling it. "Mimic Mobile Device" doesn't help. I have yet to try Override User Agent. Any help appreciated.  Thanks.

Hi,

Were things working before you updated the PC software?  Nothing has really changed in the PC software since 1.08: just some driver updates and some additional features like auto-connect that do not affect things when Klink is up and running.

Anyway, it's probably best to test for throttling first.  Could you download one of the free speedtest apps from the store:

https://play.google.com/store/apps/details?id=org.zwanoo.android.speedtest&hl=en

Then, run a speedtest on your phone when things stall (with Klink still active in the background).

Do things appear throttled?

Also, it's odd that DNS returns IP addresses in your situation.  When pinging, could you ping a host that is not likely to appear in your computer's local DNS cache?  For example, try something odd like "foo.com" or "zzz.com"  (just picking something random) to see if it'll resolve.

When you say that wifi is disabled on your computer, is the wireless connection within Windows also disabled?  To check:

- Click the Windows Start button

- Choose Run

- Enter "ncpa.cpl"

- You should see the network connections window.  For testing purposes, disable everything except the connection associated with Klink's virtual network adapter.  (Right-click and disable.)  You can right-click and enable to reverse the changes as needed.

Finally, do you have any sort of third-party battery saver app on your phone?  If so, either make an exception for Klink or turn off management of mobile data, as it's possible that the battery app is shutting off your data connection automatically after a minute or so.

Does that help?  Please let me know how it goes...

I think the XP computer was having the same problem before and that's why I updated to version 1.11e. In any case, I'm also having the same problem on a Windows 7 computer that is running the older version (1.06) . The throttling app shows no difference and the browser in the phone works fine at all times. On the WIn7 computer, the DNS does not work so maybe that is the cache issue. I do have all of the other connections disabled on both computers through ncpa.cpl. I don't have any battery saver apps and the Android saver is off, but the phone does have that evil Sprint Connections Optimizer. I will try stopping it. Last but not least, I have Wifi available at the Win7 location and when connect the phone to WiFi, it seems to run fine though I didn't test for too awful long. It's only on the cell data.

Hi, again.

Thanks for giving everything a try.  It's interesting that things work fine when the phone is connected through wifi and not data.  Just to clarify, with your Win7 machine, you see:

1) With phone connected to data and not wifi, you have connectivity for a minute or so and then everything drops out or slows down.

2) With phone connected to wifi, you have connectivity for more than the same time period as 1 and everything seems to work fine

Does that sound about right?

If so, could you try the mimic mode at level 3 or higher?

Alternatively, go to settings within Klink, choose "Override user agent", and experiment with some of the modes (usually desktop is most desirable).

Also, when you tested performance with the speedtest app, did you make sure to leave Klink's connection active?  After the successful speedtest/phone browser usage, was connectivity restored within Klink, even if temporarily?

Finally, were things working in the past?  Did this suddenly appear?  Did you change devices recently?  I've been told that some LG devices require an unusual USB mode: pull down the notification pane when the phone is connected to your computer, tap on the USB connected item, choose Internet, then Ethernet.

Sorry I haven't gotten back around.  For some reason, Klink began working on my Windows 7 PC just fine.  It's good to go.  The problem is still happening on the XP computer.

I realized that sometimes the internet connection was there - just incredibly slow. DNS would return results. Other times, it was not there at all.

I tried all of the below and none made any difference. The only change I made was to switch to Google DNS. I could not find the Internet > Ethernet setting, though I think I saw it once.  It's really buried if it's there (Android 4.2.2).

The only thing I can think of is that Sprint did a major update a few weeks back. I don't recall whether it was Android or their software.  I don't use Klink all the time and this problem surfaced when I used Klink for the first time after that update.  My XP also might have hardware problems with the USB ports.

Thanks for the help.  I'll test something else if you want.

Hi,

No worries.  Take your time.

Since things are working with your Win7 setup (using the exact same USB cable?), I'd first focus on the USB connection on your XP machine, because that's one of the few variables that differ between the setups.  An unreliable USB connection would also explain what you're experiencing.

Could you try using a different USB port on your XP computer?  Also, try unplugging any unnecessary devices while testing things out, as I've heard of one case in which a thumb drive led to erratic behavior.

I'd also check see if any firewall software is getting in the way, so you could try disabling it temporarily.  This isn't too likely, as an incompatible firewall setup wouldn't let you connect in the first place.
