Linksys Wirless Adapter not recognizing IP address
I have a Linksys router.. My laptop is wireless and works fine... However I also have a desktop that is old and does not have an ethernet connection therefore I have a Linksys wireless adapter connected to it. The desktop recognizes the wireless network but states can not find IP address. How can I fix this?

First connect that desktop to linksys with ethernet cable. then set ip property to network adapter . Set ip address ,subnet mask and gateway ip to ip property. Set ip address as the ip of network like if router ip is 192.168.1.1 so set ip like 192.168.1.15 set subnet mask as same as your other computer. Set default gatway ip as your router ip. Then you can connect internet. Let me know if you need more assistance.
There are wireless networking capabilities of the gateway that will prevent or allow specific MAC Addresses from connecting to the network. Go into the wireless settings and adjust the settings to accept the MAC address from your work computer. To find the MAC address from your computers network adapter go into a command prompt by typing cmd in the run box and typing "IPconfig /all" in the window. The MAC address is there it may be called Physical Address. It is always a 16 set of number and letter combinations divided by ":" between every 2 sets of number / letters. On your home desktop this same window will help you diagnose the problem. Your son's computer will help you with this, do this on his as well and compare the IP address with your home computer the address could be something like "192.168.1.?" the last number is going to be unique if the first three numbers match. If the IP address on your home computer doesn't match the first three octets "192.168.1" it will not get out through the gateway. If they don't match you can force it to be on the same network by setting up a static IP address by opening up the Control Panel / Networking icon and finding the icon for the network adapter that you are using and opening it up and clicking on "Properties" and clicking on IPv4 and clicking properties and clicking on Specify IP address and typing the first three octets of your son's computer and adding a fourth number that isn't "0" or "255". You can use any number between those two numbers except those numbers, and isn't the same as your son's IP Address or the Default Gateway which is the Linksys. The "Subnet Mask" will auto install but will be "255.255.255.0". The default gateway and DNS server will be the IP address of the Linksys which most likely will be "192.168.1.1". Click "Ok" on all the open dialog boxes and the computer should be able to get on the internet.
Make sure you are plugging the SMC into the WAN port on the Linksys router and not the LAN ports. Your internet connection (which is your SMC) should always plug into your WAN port on the Linksys. Any computers that you may need to plug in, like Desktops that are "wired" and not "wireless", should plug into the LAN ports on the Linksys. If you are not using the WAN port on the Linksys for your SMC modem, then that would explain why you cannot get to the internet on wireless or wired computers.
Here's why you are getting the "low connectivity" message:
Computers don't understand why the Internet is connecting or not connecting...so the "low connectivity" message you keep receiving has nothing to do with your wireless signal strength. To a computer NIC, "low connectivity" means your network adapter could not find a DHCP server and receive a valid IP address. When this happens, your network adapter assigns an IP address to your computer in the following range...169.254.0.0, and will display the "low connectivity" message until it is able to receive a valid private IP address from the DHCP server. You can verify this by going to START | RUN and typing "cmd" (without the quotes), then hit ENTER. A black box will pop up....then type "ipconfig" (without the quotes) and hit ENTER. This will show you your IP address, subnet mask, and gateway address, and you can verify that your IP address is in the 169.254.0.0 range. A valid private IP address is typically in the 192.168.0.0 range, but could also be in the 10.0.0.0 range, or the 172.16.31.0 range.
Also, make sure you have DHCP server enabled on the Linksys router for the LAN. This will ensure your "wired" and "wireless" computers receive a valid IP address.
The WAN port on your Linksys router should be configured to "Obtain an IP address automatically using DHCP".
think you have to connect a cable to the ethernet adapter of your desktop in order for you to connect to the wrt54g. uless you have a wireless lan on your desktop. also check your channels. and manually config your router through 192.168.1.1.......
Sounds like the router may need a firmware update as the DHCP service is failing to run correctly.
You can however just use a static ip address.
First of all find out the network address in use.
eg. 192.168.0.1 - 192.168.1.1 - 192.168.2.1
to find out, - start menu - run - cmd - ok - ipconfig
Log on to the client computer as Administrator or as Owner.
Click Start, and then click Control Panel.
Click Network and Internet Connections.
Click Network Connections.
Right-click Wireless Network Connection, and then click Properties.
Click the General tab, click Internet Protocol (TCP/IP) in the This connection uses the following items list, and then click Properties.
In the Internet Protocol (TCP/IP) Properties dialog box, click Obtain an IP address automatically (if it is not already selected), and then click OK.
Note You can also assign a unique static IP address in the range of 192.168.0.2 to 192.168.0.254. For example, you can assign the following static IP address, subnet mask, and default gateway:
IP Address 192.168.0.2 Subnet mask 255.255.255.0 Default gateway 192.168.0.1
Try resetting your IP address: The laptop may be trying to use the IP address from the old router.
1) Click Start (assuming Windows 2000, XP, or Vista) 2) Click Run 3) Type in CMD This will take you to a black command box 4) Type in: ipconfig/release The chart should show your IP address as 0.0.0.0 Once this has happened, proceed to step 5 5) Type in: ipconfig/renew You should now see a new IP address listed.
Also note that you need to set up your network key (assuming that you are using one) on both the router and laptop. Make sure that your router is set up to perform as DHCP server.
from what you say, it sounds as if you have your wired and wireless card connected at the same time.
This will confuse the router as it is trying to give two different ip addresses to the one pc, which it cannot do.
If you are using the wireless adapter, make sure you dissable the wired adapter as the router will continually look for the wired ip address while allocating your wireless adapter causing instability.
Next ensure you have a good clear signal from router to notebook as this can obviously cause problems.
Lastly ensure that the wireless cards TCP/IP properties are set to obtain ip address automatically, especially if your router is DHCP enabled to allocate ip addresses automatically.
