There're many things that can help. Try all fixes before you revert something, some people change everything and still got the bug, some tried only a few fixes and it worked.

1. Open your \players2\config_mp.cfg and make sure these values're set:

seta r_autopriority "0"
seta cl_mouseAccel "0"
seta m_filter "0"
seta m_forward "0.25"
seta m_pitch "0.022"
seta m_side "0.25"
seta m_yaw "0.022"

2. Go into your ingame graphic options and use fullscreen (not windowed fullscreen) and disable Sync Every Frame (VSync)
3. Disable mouse acceleration in windows settings - Tutorial
4. Go into the mouse software if you got one (use Google to find out if there is a software for mouse) and change your Polling Rate to 125

• Open your dw folder in the game directory and delete all .dat files.

• Open your dw folder in the game directory and delete all .stat files.

• Make sure that you have the correct files for the base game and a proper installation for the TeknoMW3 Server.
  • If it's still crashing, then a Script may be the cause (so you'll have to check one by one).

• Your server is most likely behind a NAT. This means that the packets sent to your IP are delivered to your home router and then discarded because nothing is listening on the port the packet is directed to. To fix this, you will need to forward your router's ports.
• Another cause could be an improperly configured firewall; you can try disabling Windows Firewall to see if this is the reason. Please remember that permanently disabling it is a bad idea; you should add an appropriate exception for iw5mp_server.exe in the Firewall.
• Lastly, make sure that you're using the most recent version of TeknoMW3. Please note that if no servers at all can be seen in the browser, it's most likely a problem with the TeknoMW3's Master Server, not your dedicated server or network configuration.

• It's a bug, you must add the following command to your server.cfg: seta sv_clanWebsite ""

• Make sure you use the latest version of TeknoMW3.
  • If the previous option hasn't worked, and you've nothing blocking TeknoMW3...read this: What do the options in teknogods.ini mean?

• Make sure that your server is visible in the Server List (My Server does not show in the Server List), solving that's the best known way to fix this error.
• If the problem persists, change the net_port and net_masterServerPort (you will have to open these ports in your Router, allow in the Firewall, etc.).
• If the problem still persists...try disabling all the Scripts, maybe some of them are causing the problem.
  • If the problem persists, join the TeknoMW3 Discord and ask for support.

• This is because your patch_mp.ff (found in \zone\spanish; or the language you've the game) isn't version 1.4.382; so you should get that file (or look for a better link).

• They may have the same ID.
  • One of you go to your TeknoMW3 game folder, then go to the "TeknoMW3" folder, look for a file called teknogods.ini, open it with Notepad and change the ID= line with a different letter/number (or two) to fix it; save the file and then close it.
