    Thanks for the help,
    It turned out to be the metric on the TCP-IP interfaces. I had set both wireless and wired to the same metric, and they were in contention for the network when both were connected. I now have the wired set to metric 20 and the wireless set to metric 25, they can now both be connected at the same time without causing the laptop to freak out on having more than one path to the router simultaniously. the wired is priority when connected, and the wireless goes dormant. when the wired connection is disconnected the wireless takes over automatically. ,

Set the LAN setting in your laptop also. It is to set manually. It is in properties of TCP/IP.

Connected Cisco - cannot get connection to my laptop - reads Limited Connectivity


"Limited connectivity" means you did not obtain an IP address from the network. Type "ipconfig" at the command prompt to check - if your address starts with 169, it is an invalid auto-assigned address. Normally you would get an address in the range 192.168.x.xxx if it is working. Did you get a wireless connection but just no IP address? In other words, does your computer indicate "connected to xxxxx" (your wireless network name)? Check the router using a wired connection to get to the admin pages. Look for SSID (name of network), security settings and DHCP settings. Your security should be set to WPA2 (and the pre-shared key should be entered in your computer's wireless settings) and DHCP should be turned on and should have a defined address pool. DHCP is what assigns IP addresses; you can define a range of IP addresses to give out (the pool). If none of this works, please post more detail such as your router model and exactly what messages your are seeing.

I cannot get my laptop to connect to the internet either wirelessly or hard-wired. I have two other laptops, connected wirelessly, and a desktop connected via hardwire. It recognizes the router but says...


if you are trying through wireless, first unplug the wire from the laptop,

make sure that the wireless switch on your laptop is turned on.

click on start, control panel, network connections/network & internet/ Network and sharing center..

right click on wireless network connection Icon, if it says disable, it means it is enabled already.

then click on status..

from here the steps would differ from OS to OS

then click on Support tab (for XP)
check the address type, it should be "Assigned by DHCP"
and if you see the IP Address starts with 169., it is a bad IP and needs to disable the connection and enable it.

if the connection type is "Assigned Manually, right click on wireless network connection icon and click on properties and click Internet Protocol(TCP/IP) and click on properties, in this window, check the option "Obtain IP Address Automatically from DHCP"

click ok and OK ..

again right click on the wireless network connection icon and click on view available networks... click on your router name and click on connect..

now check the functionality.

if you are using windows 7 or vista,

click on status, click on details for the IP Address..

We see DHCP Enabled as YES or NO instead of "Adress type"in XP

if it says no, it means it is assigned manually. to change to DHCP , right click on Wireless Icon, select properties, click on IPV4 IP address and click properties, then select obtain automatic..

then try again..

hope this works,

Cannot connect to open wireless network Invalid IP Address


Either the network requires you to manually configure your ip settings(unusual but not unheard of) or your wireless adapter is not set to get settings from DHCP. Check to verify that your wireless adapter is set for DHCP and if this is correct then you'll need to contact the administrator for the wireless AP and haver them check their settings.

How many DHCP devices are there on the network?
There should be only one. Try disabling the DHCP in your device, then your neighbours router should issue IP addresses and all will be ok.

Laptop can't aquire IP address


This sounds to be a compatibility issue with either the wireless software or wireless card. Check to see if there are any updated drivers for the wireless card at IBM's support site. If there aren't any or the card still doesn't work after the updated drivers are installed, then you might try a different/newer internal wireless card, or a universal external wireless card for use with your home system.

DI-524 One wireless connection makes others not ok


This is unusual, as it seems the router is allocating two pc's the same IP address. Go into your routers settings (internet browser and type the router address, eg 192.168.1.1)' and look at Client DHCP list and look at the IP addresses that each pc has been given and see if two are the same, they should be one digit difference, that being the last. Also go into the properties of both your pc's wireless cards and ensure that they are set to obtain an ip address automatically.
