How to increase ping time/network connection latency on Windows?
I need to permanently increase network latency in approximately 100ms, without losing packets.
Reason: On a certain server and internet game my ping is too much lower than the other people playing it. I have 15ms, when average is 150ms which gives me cheater-like advantages.
So also out of curiosity I'm looking for ways to increase my ping while keeping connection stable. What are my options if any?
I thought about VPN services, but it seems like a bad option since games use UDP?
Is there any router/software that would assist me on this?
I'm on windows.
You could give dummynet a shot:
Adding Latency
We can control traffic by adding rules that match specific packet data, and then send the packets through a Dummynet pipe with added delay or packet loss. For example, we could add a 100 ms delay to all traffic heading to xkcd.com like so:
$ sudo ipfw pipe 1 config delay 100ms $ sudo ipfw add 100 pipe 1 ip from any to xkcd.com 00100 pipe 1 ip from any to any dst-ip 107.6.106.82
The first command here configures a Dummynet pipe with id 1, creating the pipe if it did not already exist. The second command creates a rule numbered 100, which matches packets with the desired destination address and routes them through the pipe. Note that any rule that attempts to pass packets through a non-existant pipe will block traffic and throw an error, so do not forget to configure pipes before using them. Using list again allows us to view the updated ruleset.
$ sudo ipfw list 00100 pipe 1 ip from any to 107.6.106.82 65535 allow ip from any to any
Pinging xkcd.com should show a round-trip time of 100 ms plus whatever the actual current latency is across the connection.
$ ping xkcd.com PING xkcd.com (107.6.106.82): 56 data bytes 64 bytes from 107.6.106.82: icmp_seq=0 ttl=55 time=117.092 ms 64 bytes from 107.6.106.82: icmp_seq=1 ttl=55 time=124.583 ms 64 bytes from 107.6.106.82: icmp_seq=2 ttl=55 time=117.916 ms 64 bytes from 107.6.106.82: icmp_seq=3 ttl=55 time=121.067 ms
In most cases, we would want to simulate a full duplex connection by adding a corresponding rule for packets coming from the remote host, so that the delay is applied in both directions. When we are done playing with our new rule, we can delete it and the pipe as follows.
$ sudo ipfw delete 100 $ sudo ipfw pipe 1 delete
source
It looks like the dummynet project includes binaries for Windows. To adapt the commands, it should be enough to simply run the ipfw
commands from an elevated command prompt. For example:
ipfw pipe 1 config delay 100ms
ipfw add 100 pipe 1 ip from any to server-ip
ipfw add 101 pipe 1 ip from server-ip to any
I ended up using openvpn. It's a breeze to use and works pretty good. Pings is stable, no packet loss. The only future problem is the 100mb of traffic limit. I'm not sure how fast I'll get to that just by playing games.
