 Posted: Tue Aug 31, 2010 7:16 am Post subject: network issue (IT geeks please read) |
 |
|
I recently moved into a new place and everything is great but the internet doesn't work. To make a long story short, basically the guy from KT came out, did a diagnostic and determined that someone on the network was already using my IP address.
(Keep in mind that everything he said was through a translator and that my knowledge of IT is fairly limited... so... sorry if I say something that sounds dumb).
Evidently assigning me a new IP address isn't possible and my landlord is a lazy toad who probably won't get around to helping me for another month. And going to the local coffee shop so I can scam on their wifi is getting really old. I would like to be able to use Skype from the privacy of my apartment.
What are my options? Is there anything I can do myself? |

An IP address is kind of like a house address, they are unique to each person. This is assigned by your ISP (internet service provider).
Did you leave your router or something when you moved? Maybe the new resident is using your shit to get on the net? I don't understand how someone can be using your IP, unless they somehow got your info and managed to setup their router to go through your account. |

I think something was missing in the translation you got. That part about not being able to assign a new IP address is plain wrong. Are you using a router? Do you know how to use the router? It sounds like you are a bit of a novice, so I'd say find a friend and get him to change you're router settings.
Next part is kind of boring, not need to read on, but if you're interested...
I believe most companies assign IP address dynamically. So from time to time if you reboot either your computer, or modem down, your ISP will assign a new address from a list of addresses. |

The only way this is even a problem is if someone cloned your modem and is using the mac address.
They should just be able to get you a new modem and it would be fixed. |

I think the way my apartment is set up is kind of weird--everyone uses a common modem and then it's routed to individual units, but beyond that I'm not sure about the details. Anyways the only thing I have access to is the ethernet cord coming out of my wall. The modem/router is located elsewhere (not in my unit).
I've started and restarted my computer to no avail. I *wish* I could have a friend come over and take a look, but over here (unlike in the States), I don't know anyone who works in IT!
This is so frustrating.
(BTW, I'm typing this from a park near my house as I get bitten by mosquitos) |

It would just give you a different IP address if that's the case... |

Just accept your fate, and become a PCBang Troll... ya know, the ones who stay 'til their wallets or smokes run out...
if only there were ones with a cash-bar, some would take their paychecks and cash 'em there...

| Have you done your own research on duplicate IP troubleshooting, specific to your system/OS? Causes and remedies that others have posted on the net are quite diverse depending on the combination, but repetitious rebooting isn't on the list. |

Even if it were, the KT guy was wrong for saying it wasn't possible. If the problem is that you're using a duplicate address, the only solution is to either change the address of one of the devices or power it off. It's not just possible, it's the only way to solve the issue. |

What are you talking about? Where have you seen this, how often, and in how many years? |

There are only two ways this works:
Dynamic IP (most common) - You get a new IP address every so often, most of the time it stays the same but it can change.
Static IP - Your computer has one particular address it tries to use all the time no matter what.
It sounds to me like you guys are using static addressing, and someone else has the same address set up on their computer. What version of windows are you using? Or is it a MAC?
If it's Windows, see here:
http://windows.microsoft.com/en-US/windows-vista/Change-TCP-IP-settings
If it is set to 'Use the following ip address.." and then has a number like this "192.168.1.1" or similar, you're set to static. It may be that you need a dynamic address.
Check that out and report back. This is my thing and what I did for a living back in the 'States. |

It is indeed a Mac. If I had known how difficult it was to use Macs here I would have just kept my PC! Any idea of how I could check this on OSX? |

Yep!
http://howto.gmavt.net/DSL/StaticIp/mac/OSX/screen1.shtml
When you reach the part that says "Configure: choose "Manually", that's when you'll be able to tell if you're set up for a static IP or not. If it already says 'manually' and has numbers typed in there, then you are using a static address. In that case, copy down all the numbers just in case you need them again later, then change it to configure 'Automatically' (I think that's what it says, may say 'using dhcp'). Then go home and try it again. Just plug the ethernet cord in and check it out.
If not - might be something else up. Do you have access to the router by chance? Or another computer that IS working on the internet there? |

Ooh ok, nevermind, it is set to automatic... I remember checking that before. So is everything KT told me totally bunk? I can probably access the router. Do you think resetting it might fix the problem?
Additional info--my laptop can detect the ethernet network, but whenever I try to go online nothing will load. We hooked up someone else's laptop to my line and it worked just fine, so it's not like the signal isn't getting through... and my laptop works just fine at other places, so there's nothing wrong with the machine itself. |

I doubt having a PC would solve your problem.
On your Mac, go to System Preferences > Network
With Ethernet selected, what do you see under Configure? For me, "Using DHCP" is selected. |
