Connection last 1 minute, then no speed...

I've been using Airvpn for sometime and haven't had too many problems, I recently purchased a years subscription but I am starting to regret it.

 

When I connect, I use utorrent and go onto Kickass Torrents etc.... I download some files then after about 2 minutes, all internet slows to 0 b/s. Then eventually disconnects and starts again, this happens with or without utorrent open, and happens when I'm just surfing the net. I've had to disconnect and re-connect three times in the space of 5 minutes just to post this:

 

I'm really unhappy with the service now, I have to disconnect just so I can download the torrent else it only downloads for a minute at a time...

 

Couldn't paste log file so attached screenshot.

 

Please help. I recently installed the Windows 8.1 version as I was using an old one but didn't help....

Hello!

 

From the limited number of lines reported on the screenshot it seems there are routing table problems in your system. Please post complete logs in text format ("Logs" -> "Copy to clipboard" then paste here), maybe some additional clue will be visible.

 

Please never post logs through a screenshot unless absolutely unavoidable.

 

Kind regards

Hi!

​

​I seem to have the same problem: frequent disconnects

 

It seems to be something with  [server] Inactivity timeout (--ping-restart), restarting

 

Here's my log, i use Ubuntu 15.04:

Hello!

 

The observed behavior makes us think about a problem in some QoS / packet inspection / packet filtering tool, either on the system or on the router.

 

When you start a VPN connection in UDP, all of your traffic is wrapped in UDP, so everything you send out and receive through the router and the physical network card is in UDP.

 

Now, a lot of tools are configured to prevent UDP flood attacks. When they see a significant and persistent percentage or amount of incoming packets in UDP, they think that an attack is ongoing. When you start your torrent client, UDP flow usually sky-rockets and does it persistently after a couple of minutes or so. This triggers the security feature of the tool which starts dropping packets, preventing quickly communications from the VPN server. We have seen repeatedly this problem with a variety of packet inspection tools (usually aimed to QoS or flood protection). It's worth a check.

 

In case it's your ISP that does so, try a VPN connection in TCP to discern whether the problem is related to UDP or not.

 

Kind regards

Thanks for the quick reply!

 

I haven't tried connecting over TCP yet but I turned off

"Enable uTP for peer communication" in Transmission

 

And now Transmission is finally uploading and i've been connected to the VPN now for almost an hour without interruption..

 

Thanks!
