Finding out what ports are used by what programes???

[Ricochet]

Hi there guys.
First time posting

I play Call Of Duty 4 MW2 alot.
Last week I stopped being able to do this as I can't link onto the games to well.
Activision told me to check my ports.
TCP 27015 came up as blocked by another program.
How do I find out what program is locking this port?

Also I am looking to get a wireless router. Does it need to be a specific speed or size to game online with?

I am running Windows XP I think.
Any help would be really handy.

Thanks

New models have been optimized for gaming.
What sipped is your internet?
This only matters if you have a very good high-speed internet connection.
But for a Local Area Network it does matter.
Google beaming routers.
Wait... Let me Google that for you.

Hey Geek.

Tanks for replying.
No idea what speed my connection is but I know its not the top one.
Whatever the size is though it handles COD.
I am looking on E-bay for the router, is there any speed or size that won't work or are they all made for it. Thank you for the gaming router link I did see one on Ebay that came off there.

As to the port question. Any ideas? You know anyone I can ask if you aren't sure?

Thanks again and have a fab day.

To my knowledge, all routers let you use any port. Ade you can configure then to do almost anything you need. Some older routers have a "latency" problem, they are slow to react to some kinds of data streams.

Port Forwarding - Generally forwarding is done so the outside world can connect
to some type of server that is located behind your router/firewall. Web servers
, ftp servers, mail servers, computers running telnet, ssh, remote desktop, sql, and mysql are all examples where forwarding would be needed. If you are trying to forward the same application to two different ip addresses, you may have problems. There may be a way around it, refer to the software manufactures homepage for more information.

BTW, you can buy a brand new Linksys router made by Cisco on eBay for about $25, including postage, inside north America. These are overstock routers made for T-Mobile VOIP,  but function perfectly as a standard wireless router. I jeut bought one last week. Using it to watch movies over a Wii.

you can watch movies on a Wii? wow I didn't know that and I own one lol

The port thing i still don't get. I know that one of the ports is blocked by another programme. I just have NO idea as to how to find out which programme it is so I can change it.

Really frustrating.

Thanks for your advice on everything though.

Ports can be blocked by:
A Firewall
A resident AV shield
A router
A Windows background service.
Or, you local ISP provider or campus server.
Please read over the information provided on the web site I gave in the prior post.

Hey man thank you.

I didn't see the link. Got it now and working on it. `the problem is that I have a Scientific Atlanta (cisco) modem 2203 and it isn't listed on the help page!!!??? Not sure what to do now? Not sure how the *censored* I managed to get the ONLY modem NOT supported lol.

I can't believe I am this computer illiterate.

Thanks again for all your help mate.

how do you find all this stuff. I have been looking for 2 weeks now and you find it in 10 seconds lol.

Thank you

[Geek-9pm]

That's what we do. 

[Geek-9pm]

That's what we do. 

EDIT: Forgot to mention. That modem is also a router, but only has one Ethernet connection. You can buy a cheap wireless router and tie it to the cable-modem-router and have wireless in your house.

[Ricochet]

Yeah I am doing the cheap wireless thingy. Just waiting to win it on E-bay :-)

Thanks again for your help. This is still baffling me. I still don't know what the *censored* is blocking my port but I will find out

Enjoy your day Geek!
