Lag is a noticeable delay between the time something is initiated and the time when it happens. For example, pressing an "attack" button and finding that the attack doesn't happen until a second later. Latency is sometimes used to mean the same thing as lag, but in networking it's generally used interchangeably with ping time: the amount of time it takes ...

It helps to understand why you need/needed to open ports in the first place. Once upon a time, every computer on the internet had a unique IP address. However, with the rise of residential internet (and the decline in IPv4 address space), it became more and more popular to share an IP address amongst multiple devices via a scheme called network address ...

Not to get all "get off my lawn, whippersnappers!" or anything, but as someone who has been playing Quake off and on for about 2 decades now, I can tell you that there's not that much difference between 30 and 15 msec ping. I used to play on dial-up versus people on broadband connections (where a "good" ping for me was 200-300 msec, and a "good" ping for ...

I did a little bit of monitoring using Windows 7’s built in Resource Monitor (not the best monitoring tool around), and here are my observations: When the game itself is just loading, the send and receive speeds hover around 5‒8 KB/s. The largest bandwidth load was on actually loading the map with receive speeds hitting upwards of 130 KB/s, and send speeds ...

UPDATE: There is an other way I was just reminded of another way to connect to an custom Agar.io server. And it's so incredibly simple. Navigate your browser to the normal Agar.io address, but add a query at the end of the url like so: http://agar.io?[ip address here] Please note that you should not enter the ws:// prefix. Here is an example: http://...

There are several options that might help. The "official" USB-based Microsoft wireless adapter. As you've noted, it's a bit pricey, but it's officially supported and pretty much guaranteed to "just work." Use a wired-to-wireless "bridge" device. These plug into your ethernet port, but have a wireless radio in them that can connect any wired device to a ...

PNG = Ping = how long it takes you to contact the server IND = indication = how long it takes the server to tell you stuff RTT = round trip time = both of the above together

While streaming video is no problem (doesn't matter if you're watching YouTube or game feed), control latency is. Input from your controls will have to travel to remote location and then back with video. Latency is enough of a problem in network games - each realtime multiplayer game has to predict what other players do at this very millisecond, and then ...

A currently running process is listening on port 25565 and will not give it up to the new instance of your server. In your situation, it's likely the process that's "clogging" the port is (part of) a previous instance of your server that wasn't shut down properly. In Windows XP, run the command prompt with Win+R>cmd. Then run the command netstat -ano to ...

Luckily for you, Minecraft uses SRV records when looking up servers. This allows you to specify a port for each hostname. Simply create two different SRV records in your DNS zone with different hostnames and ports: _minecraft._tcp.www.server1.example.com. <TTL> IN SRV <priority> <weight> 25565 actual-host-server.example.com. ...

The Clash of Clans port is currently 9339 and the port 80 is used for the ads and also service.supercell.net. Source

You probably don't hit his hitbox. This can be caused by you (not hitting hitbox) or your internet (lag). If bleeds when you hit him on your pc and not on server (lag) or when you shoot his model, but not his hitbox. Image courtesy Blankooie.

https://eu.battle.net/support/en/article/7779 Check under performance information. PNG: Ping -- the time it takes for packet to be sent to the server and back. RTT: Round Trip (Delay) Time -- calculation-wise, this would be the same as ping, but from what I understand from the support site, my guess would be that this is number is measured with a weighted ...

While, for security reasons, I wouldn't recommend disabling your Windows Firewall completely, it might help in diagnosing the issue. This article will help you disable it and in either event enable it again. It's also possible either an intermediate router or an additional piece of virus scanning software may be imposing yet another firewall.

Since the two computers are on the same local network, as you confirmed, it might be an issue of either network configuration in general or firewall configuration on at least one of the machines. There is a support article on Battle Net about neccessary tcp and udp ports for Diablo2. I suggest to look it through, but the core info is: Diablo II/Lord of ...

Wireless works fine for Xbox System Link. Microsoft's help page for system link states: A system link cable or crossover cable for each console, an Ethernet hub or switch with enough open ports to connect the consoles together, or a wireless networking adapter for every console. The more recent version of the Xbox 360 has a wireless adapter built-in. ...

You absolutely don't need port forwarding. Port forwarding is only necessary if you host a (game) server behind your router/firewall which is not the case, neither with Diablo III nor with World of Warcraft. In both games all game sessions are hosted on Blizzard's servers. The following router setup should work no matter how many people are playing World of ...

It seems that Magicka: Wizards War uses random ports from my own testing. I tested it several times, and the result showed that it listened on port 15303, 15582, 16167, 17393, 17521 respectively in the tests. It also used port 54254, 64594, 56102, 55128, 58629 for UDP respectively in the tests. Therefore I suspect that this game will listen on a range ...

I would suggest using Evolve or Tunngle instead of Hamachi. I use Tunngle to host and play with my friend. These are more reliable ways of setting up virtual LANs. Just get in one room with person you want to play!

You can use the Chrome plugin for it. You just type the IP address out in the Start GUI.

Found the solution. Apparently the Wii U is extremely sensitive to any "invisible" proxy services on your router or gateway server. Someone had actually turned on an invisible proxy server on the gateway / router for this network. It turns out that all of the http[s] (port 80 + 443) traffic was passing through a cached proxy server to improve performance, ...

I don't know of any way of making the PS3 act like a server. It certainly doesn't support access via FTP, SAMBA or anything similar. You also cannot access data on the PS3's hard drive by plugging it into a PC. The hard drives are encrypted and the data format is not supported on PC. Not only can you not put the hard disk in a PC, you can't even put it ...

This is a well known issue of the game since its release. See here: http://www.saintsrow.com/community/go/thread/view/136781/28692595/Lag_while_in_co-op_lan The problem is not in your hardware, system or network. The problem is in the game engine. But neither the game developer - Volition, nor THQ -publisher, even commented on the issue yet, let alone ...

Getting a higher-tier internet connection will probably not improve your ping. All networked XBox 360 games are required to keep their bandwidth below 8KBps; the requirements for PS3 are likely similar. With a 4mbps (500KBps) connection, you will be using less than 2% of your total bandwidth. Your ping is the time is takes a packet to make it from your ...

Probably not. The biggest thing you can do to improve your performance is to purchase a higher-tier internet speed with a larger bandwidth. As you've probably figured out, the 4 mbps you're getting is nowhere near the limit of your router (150 mbps). This implies that the router is more than capable of handling the data you're sending through it, and the ...

As this is happening across two different computers, I suggest it might be a ports issue. Make sure the ports for the games you want to play are open. This site is a good place to start if you don't know what to do, and this page is useful in working out which ports each game requires. Alternatively, it could possibly be a firewall issue if both your ...

Here are some more things to try before giving up: Check that in your friend's server.proporties the server-ip is set to your friend's internal ip NOT localhost or 127.0.0.1 Try with a LAN server, have your friend open a world to LAN (with cheats) and type the command /publish, this will give you the port you need to connect to so connect to 192.168.2.16:[...

You posted seven hours ago, so the immediate problem may have been resolved by the reboot suggested in another answer. However, as a more fine-tuned solution, you might find this answer valuable: How to close TCP and UDP ports via windows command line. Rebooting the entire machine will end all processes, freeing all ports used by those processes, and that ...
