router help

[gamfrkI]

i was looking a the devices that are connected and i found 2 that just use an ip address

192.168.1.81

and

192.168.1.83

what are they?
and is there a way to take them off the router connection?
(they use the wifi signal and the router uses a wep key)

router i use is a 2wire 2701HG-B

You can use a network sniffer to determine what they are. I use Languard Network Scanner 2.0 for this.

SuperScan 3.0 is one of the best scanners. The IP's you listed are local to you so they will be something on your home network, a phone, iPod Touch, Wii, PS3, laptop, iPad, even possible your TV or media box. Dont be too alarmed, check the traffic going through the router to see if the devices are using any bandwidth.

ill get both programs ill post what they are later

EDIT:
the languard network scanner 2.0 didnt find any computer and superScan 3.0 i coudnt find for download

The IP's you listed are local to you so they will be something on your home network

that's what i was thinking. 192.168.* are always LOCAL! my local ip is 192.168.1.27 yes i remember it. and my other local at my house is 192.168.1.101 yes that is random. i guess 1-100 were taken? lol

Can you ping the address? When not it could be down. Can be a machine that's not running at the moment.

Do you have wireless?

[gamfrkI]

Hi lad,

Go to: <start><execute>
Type: cmd

Then in the command prompt enter:

Code: Select all

ping <the unknown ip>

See if it replies with something that contains:
Response from <the unknown ip>: ... bytes ...

Check with:

Code: Select all

ipconfig /all

if one of the IP's isn't just your DNS or gateway or something. You will also receive your OWN MAC adress from this command if you want to enable your MAC adress in the router (and block all others perhaps).

When you are sure these IP's aren't supposed to be in your network, you can propably block the corresponding MAC adresses in your router.

You can find the MAC adresses that goes with a networkcard that got an IP by using the following:

Code: Select all

nbtstat -a 192.168.x.x

and fill in the x's. At the bottom you will find the MAC adress you will need to block.

Be very sure the MAC adress isn't supposed to be in your network before you block it in your router.

Good luck

Dough.. .

@ cmd:

Code: Select all

arp -a <unknown ip>

Also works to get the MAC from a (remote) NW card.

my router reset a while ago so now those ips are gone
