Mordhau

Severe lag and packet loss issues

Ever since I started playing this game about 3 or 4 weeks ago, I have been having issues with latency upwards of 700 ms in every server I've tried joining. Sometimes it will go down to about 40 ms for a moment or two, but most of the time it is much higher. I am positive that I am matchmaking in my region, and when using the server browser I will find plenty of servers where it says my ping is about 50-80 ms, but then I join and my latency is in the hundreds (while mostly everyone else is well below 100 ms). I do not have even minor lag issues in any other games that I play on any device in my house, but without fail I have issues in Mordhau.

Is there some kind of Windows or router settings that could be interfering with Mordhau specifically? Or is this really some kind of issue with Mordhau that only affects a small group of players such as myself? Has anyone with similarly severe lag issues managed to fix it?

Proof in case it's needed

My ping/latency is always higher than whatever the ping says in the server browser. As a result I often end up with 70-120 ping/latency on most servers I join, with random ping spikes every so often up to about 300, which includes packet loss. My ping seems to a bit more stable in some non-official servers.

You could try forwarding the ports (I'm sure someone on here can explain how) in your firewall &/or deactivating your anti-virus whenever you play. Also try non-official servers via the server browser, but stay away from icefuse servers as they always say x ping, but when you join them almost everyone has a ping of 200 upwards.

So I had given up for a while, but today I came back and tried to play by connecting to my phone's hotspot and it worked perfectly fine. My latency was around 70-100 ms, but that's to be expected using a mobile connection and it never spiked like it did when connecting through my router. Never rubberbanded, didn't get notifications about packet loss, and I tried multiple different servers which all worked the same.

That pretty much confirms it's not a firewall, AV, or server issue, but I did check anyway just to make sure that Mordhau was allowed and it is. My router has UPnP enabled so shouldn't I not need to forward ports? Can you even do manual port forwarding with UPnP enabled? If not then port forwarding is not an option as UPnP is necessary for other things here.

I don't know what else to try. Although it's a bit of a pain to set up and switch to my hotspot every time I want to play, I at least know now that I can do so. However, it would be really nice to figure out why this game will not work on my home Wifi when every other game I own does just fine.

Update in case anyone else comes across this: Turns out 99% of my network issues with Mordhau occur only on my 5 GHz network. On my 2.4 GHz network, I get a steady 40-50 ms latency with only occasional lag spikes - maybe half a second in duration and occurring only 3-5 times a match at most.

I still have no idea what the underlying issue is here as I don't have issues with other games on the 5 GHz, but I'm absolutely positive it is causing issues with Mordhau.

Why are you even using wifi?

I've been getting this a lot, but I think people don't realize how much better WiFi is than it used to be. The router that is set up at my current residence is not as good as my own router (which is not set up for various reasons), and even still my ping to the router averages less than 1 ms with a maximum of 7 ms and 0% packet loss, and it is capable of supporting more bandwidth than our ISP plan provides (200 mbps).

It may still be better to use Ethernet in a place where your connection to a wireless router is significantly obstructed or there is interference, but with my current setup my wireless connection is practically no different than a wired connection. Especially considering that I am not competing in tournaments or anything, I'll definitely take the convenience of WiFi over a minuscule latency advantage.

Hard for people to help if you're using WiFi though. The amount of people that blame the game for problems when it is likely a misconfiguration on their part. Using wifi is a huge factor.

I totally get that, but I did make note in my post that this is an issue specific to Mordhau. I play many other games both on my PC and other devices and have, in all honesty, not had any kind of severe or long-term issues like this with any other game (at least not in any recent timeframe that I can remember) regardless of which network I am on. Also, I had significantly better success using a mobile hotspot which, although the WiFi connection to my computer may be quite stable as it's right next to it, the actual cellular signal was certainly not. Even when my cell signal did degrade, the lag issues were hardly half as bad as they always are on my 5 GHz network.

Although I have checked to make sure everything is set up right, it is certainly possible that there is something wrong with the way my computer or router is set up which is causing the issue. That said, it is still only an issue with Mordhau meaning there is something specific to the game that is at least contributing to the issue.

Although I haven't been super motivated to look into it more since I can (and do, perhaps a bit much...) play just fine on my 2.4 GHz network, I will certainly continue to try troubleshooting the issue more at some point and update if I find anything new.
