This computer currently has limited or no connectivity

I am currently trying to connect to two of my access points and I get a message saying that the connection was unsuccessful. The message also says "This computer has limited or no connectivity to AccessPointName". The access point are Cisco Aironet 1200 devices, and we have 4 of them. 2 are live and two are not. The two that are not live, were turned off, until yesterday, when I changed their SSIDs and turned them on. The other two that are live, are fully functional (and these two live ones share the same SSID). All four used to share the same SSID, but I need to use the other two for different purposes.


Note that one of the non-funtional AP was reset to factory default, by me, yesterday. I connected to both of them yesterday, and even one of them this morning. It was fine. I have turned one of them off and on. No change.

Look to see which one you are connecting to.  Check the properties under 'connection' and look for the  AP mac address.  Compare this to the stickers on the units (or inside the configs).
When you know which of the four you are connected to, then you can work out why you do not have a connection.

Do you have an IP ? Is it valid ? DO you have default gateway and subnet mask etc ?
Does it make sense ? can you plug into the network and set those settings and be able to get out to the internet that way ?

Check your IP address. Are you getting a APIPA address 169.xxx.xxx.xxx. IF you are then statically assign it to a address that is vaild for example 192.xxx.xxx.xxx. This will depend on a computer that is connected and working. Make sure you have a vaild IP address, subnet, Default gateway and DNS. Use 4.2.2.1 as a DNS if you need to.


Also try and ping your default gateway and try and ping yourself 127.0.0.1 as see if you have basic connectivity.

Let us know.

More likely, your Cisco AP does is not issuing DHCP address or hardware mulfunction. It can be client connectivity issue- you can check with "ipcofnig" from client PC in CMD.
Check configuration, and maybe post some in here.

One of the AP's had MAC address filtering (I forgot). I removed the MAc filtering, and it's okay now. The other one started working, after I put back on it, the SSID name that is shared amongst the other APs. Thanks for your comments.
