Is my neighbour using my wireless?

lewis

I was in looking aroung my BT Voyager 2110 config. and I came across this....



Now I`ve nothing to do with Eircom, I`m Vodafone....I pinged the IP and got this...



Is this someone else using my wireless, or what does it mean?

Any help would be great, cheers

What does ipconfig /all show?

Is that your MAC address in the DHCP table? Maybe the name "eircom" was put there by someone hoping to look inconspicuous.

Play it safe. Change your WEP key

WEP can be cracked in minutes. Try and use at least WPA if you can.

Or you could have some fun...

TBH if you don't know how to change your WEP key then you haven't much chance of ****ing with their use of your internet..

Hi,

You can see your 00-1B-77-19-47-6F machine (aka Colms-PC) has been allocated an IP address by DHCP. That's as expected.

Someone has also recently connected using their iPhone. Do you know who Claire is?

That eircom one looks very suspicous alright.

Who/what is Benita?

- At the very least change your password

- Try to change from a WEP password to a WPA or WPA2

- Don't broadcast your SSID. This means that users connecting for the first time have to type in the network's name as well as the network's password. The network name doesn't appear automatically in the list of networks to choose from.

- Consider restricting access to certain machine only using MAC addresses (i.e. only allow your machine, Claire's iPhone, etc.)

If you do all of the above, your neighbour won't have a hope in hell.

You could record all the packet information (using wireshark), and if anything untoward is found (such as porn), you could mention that you may have to tell his wife/girlfriend about his internet habits.

Benita is the missus, Claire is a friend, like I said when I look at the other wireless around there are a few Eircom one`s, so wouuld`nt it be someone using my wireless.


Plebs I`ll try and do all that stuff and if I get it all done will that Eircom one be gone from the DHCP list?

Start by just changing to WPA security and a decent length security key (e.g. at least 8 characters including number(s) and both upper & lower case characters).

Keep the new security key to yourself and that should be enough.

Dave147

Perfectly calm, just pointing out that if you can't change a WEP key then what chance have you of ****ing with their internet? My guess is none.. No offence.

lewis

Well I went into my router settings and MAC address control, allow mode and put in the MAC addresses I know and that Eircom one is gone for now, so I`ll wait and see if it returns.
I have`nt switched to WPA, if it returns I`ll do that, fingers crossed!!

Why not? That is by far the most important thing to do.

Remember that if your long lost cousin from Montana stays for the weekend and wants to use your WiFi, you'll have to get his MAC address and type it in!

Try and figure out how to enable a better encryption standard such as WPA or WPA2 and you'll be laughing.

If I were you, I'd fock with my neighbour. lol.

lewis

Well its been about a week and there`s no sign of that Eircom yolk and connection is stable, if it is/was a neighbour why would they use my wireless if they have an Eircom one?
Its working grand at the moment so like I said if it happens again, I`ll go WPA, will that make you all happy,

Plebs, how did you know I had a long lost cousin from Montana?? Maybe its you!! hehe

The hostname 'Eircom' that you saw is most likely just the name of a device that was connecting to your wireless. It doesn't necessarily mean that the person had Eircom wireless themselves.

lewis

Well either way Eircom or Paddy Cricket, it was someone that was using my wireless.....
