Constant Disconnections and Latency Spikes

Ever since patch 1.0.3, I've been experiencing constant "unexpected disconnection has occurred" messages, sending me back to the log in screen. I also experience frequent latency spikes, which causes the in-game action to freeze up. When the action resumes, I usually find my Character dead. (A reason I only play in Standard League these days).

Because I have a Sound Blaster X-Fi series sound card, I use the "-swa" switch in my PoE command line. My system information is included below, with some connection information.

And while I'm thinking of it, my 4 CPU cores are running at a temperature of 43 to 45 degrees, Celsius. My GPU is running at 38 degrees, Celsius. (If that matters).

I have contacted my ISP three times. Each time, they sent a technician out to my house to check the equipment and the signal. They have found no problems so far. I have a cable connection and own my telephony cable modem (to avoid rental fees).

Note: The WinMTR and PingPlotter results were taken on one of my better days. The SpeedTest and PingTest results are typical with my connection.

I could not include the entire DirectX information, as it exceeds the 50,000 character post limit. I've tried to include the important information. (Let me know if you need more).

I run PoE at a resolution of 1280 x 720. And, before anyone asks, I have all the latest device drivers installed.

Were the WinMTR and/or PingPlotter traces capturing when you were experiencing the issues? I want to ensure that your lag and disconnects were captured in the trace. A trace without a capture isn't very useful because it doesn't show the network state at the time of the problem. Only before or after... when there might not be a problem.

I ran the WinMTR and PingPlotter trace routes according to the instructions in this thread:

How to: WinMTR / trace route

How to use PingPlotter

It does not state to run the trace while the game is running. (If that is what you mean).

I used "US.login.pathofexile.com" for the Host in WinMTR, since I log in through the America Gateway and "www.pathofexile.com" for the Host in PingPlotter (as per the instructions).

After I posted the OP, I went in-game and spent about an hour trying to get from the Imperial Gardens Waypoint to the Waypoint in the Sceptre of God on Merciless Difficulty, which I haven't tagged yet. I was constantly getting killed from latency spikes. At least, this left my Town Portal up, so I could get back to the Sceptre of God. But, whenever I was disconnected and had to log back in, my TP would be gone and I'd have to fight my way through or run past hordes of monsters to get back to the entrance of the Sceptre of God. I finally got frustrated and quit my game session. (I still haven't tagged the Sceptre of God Waypoint. And I'm not looking forward to going back in until the connection issues have been resolved).

although the thread doesn't state you should run it while experiencing the issues, that is usually the best way to locate a problem.

WinMTR captures the network conditions over time. If you just have a crappy connection in general, then the trace might be lucky and capture it while it is in the crappy state. If you have a mostly stable connection but sometimes experience issues, then capturing DURING the issues gives us the best chance to locate the problem.

Think of it like taking an "accident" or "crime scene" photo after it's already been cleared. Doesn't do much good right? We need to capture the scene at the time the problem happens so we have the best evidence to detect the problem.

Okay. Thanks. I'm not sure I should run WinMTR and PingPlotter at the same time. This is what I'll do. I'll run WinMTR and play the game until I experience the issue. Then I'll run PingPlotter and start another game session until I, again, experience the issue. I'll post the results as soon as I have them.

You don't necessarily need to run PingPlotter and WinMTR at the same time.

The only reason to use PingPlotter really is to "validate" results, and in cases where WinMTR packets are blocked/filtered and prevent the WinMTR from properly resolving.
Okay. I spent about 30 minutes in-game. (15 minutes running WinMTR and 15 minutes running PingPlotter). I didn't experience any disconnections this time, but I had plenty of latency spikes. (Very frustrating!)

Here are the results.

Looks like you've got something going on with your home network. Something is causing 4 second ping spikes, and it's not the PoE servers... it's showing on your first hop. That is the network between your PC and your Router/Modem.

I'm not sure if it is a hardware or software issue, but something is causing those spikes... and it's not your ISP or the GGG servers.

If you're using wireless, try hard-wired. Double check your cabling if you're wired, and perhaps try rebooting your PC and Router/Modem. Also check if anyone else is using the network (maybe unplug them) and see if they are utilizing a lot of bandwidth.

Hopefully you can figure out where the issue is, but it appears within your own network somewhere. Good luck.
Thank you for your help.

I only have the one computer. My connection is wired (not wireless). I run an Ethernet cable directly from my computer's internal Ethernet card to my telephony modem, which is about 6 months old. The Comcast technician ran their coaxial cable directly from their service (the wall plug) to my telephony modem.

In the last 2 days, I've tried Comcast's instructions to reset my modem 3 times. This involved unplugging all cables, including the power cord, from the modem and waiting at least 30 seconds. After plugging the cables back in, I pressed and held the reset button on the back of the modem for a minimum of 10 seconds. Then, I let the modem reboot.

If what you say is correct, then the problem would be my Ethernet card, telephony modem or the software drivers. Would you, by any chance, have any suggestions on an easy, inexpensive way to test these components? (Comcast technicians couldn't find anything wrong).

It doesn't have to be hardware causing your problem either. Could be software on the PC filtering packets, taking too much time, etc.. firewall or AV are common causes.
