Question

Wireless Connection Not Working - Limited or no connectivity

Asked by: n00b0101

I use Comcast High-Speed internet and I'm currently trying to set up my wifi.  It used to work like a charm, but I've recently had to upgrade my router, and now my wireless connection isn't working anymore.  On my host computer, I'm able to access the internet fine, just my wireless connections that are problematic.  I get this "Limited or no connectivity. You might not be able to access the internet or some network resources. This problem occurred because the network did not assign a network address to the computer."

I've clicked "repair" but that doesn't solve the problem.  

I've tried ipconfig /release and ipconfig /renew, but that didn't solve anything either.  

ipconfig /all produces the following:

Connection-specific DNS Suffix: comcast.net
...
Dhcp Enabled: Yes
Autoconfiguration Enabled: Yes
IP Address: 192.168.1.4
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
DHCP Server: 192.168.1.1
DNS Servers: 192.168.1.1

Can someone help me out here?  Thanks!

It seems that DHCP is working ok with your WiFi router at this point so release /renew will have no effect. Check if your computer is running a firewall software. I wold recommand you to completly disable any kind of firewall but since it is a WiFi connection you could do that only for a short time. Check for a secondary network adapter (the one that is incorporated in your PC motherboard) that might also have an IP address, default gateway and DNS assigned. If you are running XP SP2 this patch might help even if i think it is mostly related to DHCP Issues http://support.microsoft.com/kb/884020
Another common problem is the corruption of Windows TCP/IP stack, you can use WinsockXPFix a tool widely available with a google search but keep it last on your option list
Since you have a small network I would strongly suggest against DHCP, you should assign static IP address to your computer(s) and I am shure that your problem will magicaly dissapear ;) .

Unfortunately, I tried all of these suggestions, and I'm still receiving the same error message.  Any other suggestions, or information I should post that may be relevant here?

If the wireless client is configured for automatic addressing and a DHCP server is not present, then Windows XP assigns an Automatic Private IP Addressing (APIPA) address that begins with 169.254. With an APIPA address, the wireless client might not be able to reach other nodes on the SOHO network and will not be able to reach the Internet. If an APIPA address is assigned to the wireless connection, computers running Windows XP with SP2 display "Limited or no connectivity" for the status of the wireless connection.
This usualy is caused either by the fact that your computer is unable to properly comunicate with the router and/or it's DHCP server

1) Make sure you have DHCP Client and DNS Client services running on the computer you are connecting via WiFi

2) Try to disable any kind of security over the WiFi connection like WEP and MAC Filtering.

3) check for multiple running firewalls on your computer. Disable them if this is the case

3) If nothing else works disable your DHCP server on the router and have your computer assigned a static IP in the same class as your router
