Internet Routing?(im in the tech section too much -.-)

So today after being using a 1 modem port between two computers. we finally got a router from a friend. its just not that good. the signal hardly reaches my attic conversion from my front door. (through two floors and the legnth of the house) but the other computer is much closer to the router and has no problems.

So after being on today to my ISP finally got both computers connected to the internet wirelessly and my connection is too bad to play gw with. but it was fine coming directly from the modem to my PC, and not through the router.

So i would ask anyone reading this thread this:

Can i make my computer connected through a Ethernet cable, and the other wirelessly?. If so how?

I connected my computer up with the local area connection, and it said there is an Ip address conflict and to change the Ip of one computer on the network. As the Wireless connection is "obtain automatically" and the wired i put in the information myself.

How do i know what number to change on the Ip, if im putting it in manually?

If i need to add any information or anything just say so ill do my best to help sort this out.

Thanks for reading this.

Most routers have both wireless and ethernet ports.
Just activate wireless (and use wireless security, WPA at the minimum--keep people out of your bandwidth), and connect/wire in as needed.

Wireless routers are not created equal - some are much stronger than others. A router may go 100 feet easily in an open field, but every wall or piece of furniture it passes through diminishes the signal greatly. Also the wireless card or adapter on your computer will affect this as well.

What im syaing is i cant get my computer to connect up wired. and gave the reasons why. im trying to avoid the i/p conflict and get a wired connection working.

Simple answer - you need to change the last digit of the IP address. If, for example, your computer's IP address is 192.168.1.100, change it to 192.168.1.101 (If there's still a conflict, try 102, etc.)

Long answer - The router should be set up to be a DHCP server, which would assign the IPs automatically. You need the computer to obtain the IP automatically AND have the router set up to give out the IP.
If the computers connected to the router don't have an IP in the form of 192.168.1.xxx, then there's a good chance that the router is not set to act as a DHCP device. (192.168.1.xxx is more or less standard for home networks).
If the router is set to act as the DHCP device, there should be no IP conflicts (unless you have over 100 or so computers.) On the routers set up page, make sure that DHCP is set to "enable" - or whatever the setting would be in your particular model.

While what Quaker said will work, I would prefer a simpler option. Disable your wireless network, connect your cable to the computer. When you are done playing disable your wired network turn on your wireless.
Some computers will report the same MAC address to your router on both the wireless and wired ports (my mom's Acer laptop does this), which means that Quakers DHCP solution would not work as it would assign the same IP to both ports.

In the router setup, there is often a setting for "DHCP range" or "DHCP start address" + "Number of DHCP addresses" This usually, these days, defaults to 192.168.1.100. If this number exists, note it.

Disable wireless if you're going to use wired on the same computer. While not strictly required, I've never seen a network stack in any of the major OSes not get confused now and then by that setup.

If you continue getting the IP conflict, go to the network setup page and manually set your IP address to one outside the DHCP range (and not the same IP as the router) and your gateway to the router IP. Depending on your router (most modern ones do it. Check your manual), you should also set your primary DNS server to your router IP as well.

If that STILL doesn't work, check your cable (long cables can get pinched/frayed/broken in very annoying places) and use the working computer to scan your network for machines using something like "Angry IP Scanner" or nmap. You should not see more "hits" than router + number of computers.

HTH

Make sure you have different IP address in each computer , you can use one or up to two wired connections (depending how many ethernet ports your router have) . Do what people said here , enable DHCP in your router setup page. To know how to enter there read the router manual or just tipe 192.168.1.1 on a internet browser to access the router setup page.

It is recommended to enable mac filtering in your router too , so you can setup what wireless computers / devices may connect to your network.

About the signal (wireless no wired) , check if your router is dual band , 2.4ghz or 5ghz, if it is dual band try to connect to the 5ghz band, if your router is dual band and your wireless computer only find the 2ghz band then that means your computer only have a network card for capable of 2.4ghz no more. If your signal is bad try to put your router in a high place, like on top of a table or a stand etc. the higher the router is the better signal you will get, make sure that there are no obstacles infront of your router, in example, the router is in within two tables or wall . If your router have an external usb antenna , make sure the antenna is in a high place etc. same as I said before.

Try that and see if the connection is better, now , what KZaske is saying is strange , two devices with the same mac address ? thats very weird , but maybe possible, never saw that yet.

Anyway , once you have the DHCP enable should be ok, and don't forget the range of ip address , your first ip address should be 192.168.1.100 , the next one should be 192.168.1.101 on so on , make sure each computer / device have a different one (check the last numbers ) but as far as I know , in order to configure your IP address in your computer / device, you will need the DNS address from your ISP , if you don't have those , you cannot configure ip address on the computers/devices.

Thanks alot guys. Im at the stage when knowing about computers and networking that i know a bit.. but not alot. i done what you guys said and it worked.

i set the I.p to obtain automatically and it was fixed.

Thanks again.
