can I change IP with router??

[brannsiu]

I've got a generic wireless router which is Netgear N300.

my ISP provider does not have a cable modem provided, I just connect the lan cable to the wall lan port.

I've got a laptop PC and desktop PC. I 'd like to have different IP.

Is it possible??

No.
Your IP address is handed to you from the ISP, or whatever other device you are connected to.

What is on the other end of that wall LAN port?

I trust that when you plug in either the laptop or desktop into the wall lan port outlet you get network/internet access is that correct?

Do you know where the wall LAN port is connected - the other end of the wire? Where it is located?

Somewhere at the other end of the wire to that port there should be a patch panel, a switch or hub, modem/router, a router, or perhaps a switch or hub from the router.

If you intend to use your Netgear N300 for wireless connections it will need to be configured correctly and that configuration is dependent on other devices in the wiring path to your wall lan port.

But if you want to just be able to connect two wired devices a simple hub should work and the router providing current service would just assign each computer its own iP address when the computer is turned on.

Sort of a general answer as more information is needed.

I'm living in a building. there is possibly.. possibly no way of getting to know the modem-like things because it's outside my room
but yes, it's still possible with a ladder at the night or ask the ISP

but what should I ask the customer service about their modem? model? any specified values i have to know? and what's next in that case



Yes you are right my laptop and PC plug into the lan port on the wall and then connect to the internet immediately without any username and password

?

The ladder part I can understand... The "at night" part I do not understand unless there is some translator software involved with the postings.

Why "at night"?

Who manages your building and/or the network?

My suggestion is that you speak with that person and find out (as also suggested by USAFRet) what is on the other end of that wall jack.

My concern is that your plan may violate some residential rule or policy with respect to additional devices.
