My isp gave me a wired modem and it uses dynamic ip, so i just set up a connection using automatic ip and i can connect to internet using an ethernet cable. but when i try to set up a netgear wireless router, it says that my isp uses static ip, which they dont use. i dont know how to fix this issue with the router. Thanks for the help.

Most likely your router is not configured correctly. you did not indicate which ISP you have but since you can get on line when connected directly to the modem I would assume that one of two things is happening: your ISP provided a static IP which is in your computer and the the modem is configured as a bridge. - this option is very unlikely as most IPs are assigned dynamically.
option two your modem is configured as a router and is getting its information assigned dynamically from the ISP. In this case you will need to log into the web interface of your router (typically 192.168.0.1 if not try 192.168.1.1) with login of admin and password for the password. make sure the WAN interface (Internet interface) is configured for automatic configuration (DHCP) save the settings in the router. reconnect the modem to the router and power off the modem first and then the router. power cycling the modem and router will clear out the arp cache in the modem. after they power back up you should be able to go back in to the router and verify that the router has obtained an IP from the modem.
Most residential subscriber services use dynamic IP addressing. Dynamic IP addressing is automatic from your Internet Service Provider (ISP). Linksys home based products such as the one you have should be setup up for this configuration out of the box by default, and require no adjustments to the IP configuration of the wireless router. You should power down the DSL modem and Linksys, then connect them, then reapply power. This will clear the DSL modem if it was connected to another device such as a PC. This is important as most cable and DSL modems use something called MAC address binding that will only allow one device to connect to it directly at a time.
How does she connect to the internet on the other PC? If a cable or ADSL modem is used then this needs to be connected to the WAN port of the router. Other wired systems need then to connect to the routers LAN ports. The wireless connections sound like they are already working connecting ok. Any trouble that might come after connecting in this fashion might come because the router is set to a fixed IP. Router needs to be set to connect via dynamic DCHP option.
Once you have your router connected to your Modem, connect your computer to any open port on the router, and with your Web Browser, go to http://192.168.1.1 and log in to the router. Login is (default) login name is admin and default password is just a blank field. Once you have logged in to your router, go through setting up things like IP address (leave at "Get Dynamically from ISP". Same with DNS server --- "Get automatically from ISP". MAC address should be already filled in. Click Apply. You should be good to go for wired router use, and if you want to use it wirelessly then you need to click "Wireless Settings", pick your SSID (Name of your network) and any security you choose. After this you ought to be set for wireless access as well.
usually by connecting to it at the address 192.168.1.1
but you should download the manual to make sure.
once your connected, you need to set the cable modem setting (if any) or just set it to Automatic or DHCP for it to automatically connect to the cable modem, and then send out the signal on the wireless.
connect ethernet cable of your computer lan card to ports on linksys router ethernet port. then acee in browser tis link http://192.168.1.1 then username is admin pasword also admin.if not login then try username blank and pasword is admin then set dynamic ip adreses enable .asl oset in your tcp /ip properties in lancard.set it to obtained dynamic ip aderss auto.aslo make sure in link sys that dns also automatic geting from isp. thatys it. u get INTERNET NOW FROM YOUR ISP.
When dealing with a router there are multiple IP address scenarios, on the internet service provider's (ISP) side you can have either a static or dynamic IP address. I believe most routers by default are set to accept a dynamic IP address from the ISP. Where the ISP permits the router can also assign IP addresses to each device that attaches to it allowing a single ISP connection to be shared by multiple computers. This is also generally the default for routers purchased for home use and the wireless adapters also accept the dynamic IP assignment from the Router. With the logical discussion out of the way I believe you wish to discuss the physical connections to be established. Again this is a generic discussion not knowing your specific environment. port types - I will refer to phone ports (technically RJ-11 either two or 4 wires (these cables plug snugly into phone jacks and modem connectors) and ethernet ports (technically RJ-45 which are 8 wires and to big to fit in phone and modem ports) First you have a connection provided by the ISP for DSL this is your phone line where filters are attached to your voice phones and an unfiltered phone connection goes into the DSL modem's phone port often with an ethernet port. If you have cable generally the cable company provides a connection to a cable modem which has an ethernet or other port to connect to your system. The ethernet port generally connects to the wan port (generally separate) of your wrt54g router with an ethernet cable. Computers can be attached to the wrt54g router using the 4 ethernet ports in a group provided they have an ethernet port too. Wireless cards connect to the wrt54g router through radio waves and with antennas on the router and often internal to the wireless adapter (often embedded in a notebook computer today). These details are enclosed with your ISP's instructions and the Linksys router instructions often with pictures to help the explanation.
