CSS server starts to stutter (latency)

[†Fragenstein†]

The server runs fine for a little while, then stutters really bad. The latency goes through the roof. Ping will jump from 30 up to 400 and then keep going up and down.
The server is on a Windows 11 machine and has plenty of bandwidth (over 300mbps down and over 20mbps up). I also ran some latency tests and it shows almost 0 packet loss, so I'm stumped as to why the server keeps bogging down. I changed some settings in server.cfg...

// Bandwidth Rates
sv_maxrate		"0" // Set this same as min. rate if you not have enough upload bandwidth
sv_minrate		"52800"
sv_maxupdaterate	"66" 
sv_minupdaterate	"20"
//sv_maxcmdrate		"66" // Use if you like
sv_mincmdrate		"30"
net_splitpacket_maxrate	"1048576"

but it hasn't helped. Any ideas?

i had gone to look but got no response in game for the server address id assume maybe your working on things and its just down right now.

usually i prefer launching and handling game server address utilizing straight I.P and Port
steam://connect/192.223.31.114:27018

You can also query your servers as well like so

Thanks for checking the server, and for the info. I'm pretty sure the issue was with the router. I reset it and reconfigured it, but the pings were still all over the place. I just hooked up a new router and am hoping the issues are finally put to bed.

[dr.N0]

let me know when its up again ill check it out bro!

Seems pretty stable now, let me know...

i was able to add gungame[DM] Turbo w/Sticky Nades and query information in game but was unable to connect to it. maybe your server is out of date as counter strike source sdk got updated recently. my counter strike source is up to date and i am able to connect to my own running right now so thats odd i get no error either its just that the connect button is grayed out im not sure the deal i should google it but latency looked ok

[†Fragenstein†]

It turns out it wasn't the router. It ran fine for a few games, then went to ♥♥♥♥ again. The last thing I'm trying is replacing the Wireless Adapter Card, which will be arriving today. The server PC is in another room, but not far from the router. I would hook it up via ethernet cable, but I'm not drilling holes in the wall to run the cable. Besides, the server ran fine for years via Wi-Fi connection, so I'm hoping it's just the Adapter Card. I'll find out later today.

[kleiner blauer Elefant]

You have the server in the same LAN as your client? Does the latency issue occure when connecting via local IP too? Or have you only tried NAT loopback?

[†Fragenstein†]

Installed the new adapter. Fingers crossed.

Noticed this in the server console. I've never seen these entries before and googling the cvars hasn't really given me a clue...
