Problem with AT&T Connection - Post advised by live chat agent(1)Category: Technical SupportFebruary-9-2016 7:42 PM PST (8 years ago) Go to Blizzard forum post
Hello Devs :)

I've run into issues with a data center and serious packet loss, making the game rather unplayable. I've spoken with a live chat agent and he recommended creating this post to get attention and possible resolution.

Support Case ID: 53860871

Here is my pathping results:

Hey Lynx,

I noticed on the pathping that the connection from hop 2 to 3 is experiencing 1% of data loss. That would be when the data actually leaves your house and transfers to your ISP's network.

There could be an issue there but 1% isn't a strong indicator to know for sure. Please use WinMTR to test again. WinMTR tests the connection over a period of time so we can get a better picture of what is going on, opposed to a pathping which is a single moment in time.

- Download WinMTR
- Extract the download and then run either 32 or 64 bit as an admin.
- Use 12.129.222.10 for the Host field and click Start. Let the test run for 5-10 minutes. Play the game during this time if you can.
- Stop the test and click Copy Text to clipboard.
- Post the results here please.

Thanks for the info Lynx,

When the data jumps to hop 5 on the route, there is a massive loss of data - 62%. That is likely why you are experiencing such severe lag spikes.

Now that you have the WinMTR it would be best if you sent it to AT&T when communicating with them. With a clear picture of where the issue lies, they may be able to better assist.

We aren't able to directly change anything on the nodes that are dropping packets since it is on AT&T's network. I'll leave the thread open though, if other AT&T customers are experiencing the same issues they can chime in. The more players that report issues the more attention the issue gets. ;)
