Hello, Long time lurker... finally have a problem I can't solve through Google. I have my PC wired behind a Linksys WRT54G wireless router. This morning I could not access the Internet via Firefox or IE7. My laptop could access the Internet via wireless connection and wired connection. I ran the network diagnostic and received the following output: Last diagnostic run time: 10/10/07 10:55:26 DNS Client Diagnostic DNS - Not a home user scenario info Using Web Proxy: no info Resolving name ok for (www.microsoft.com): no warn Unrecognized WinSock NSP: NWLink IPX/SPX/NetBIOS Compatible Transport Protocol No DNS servers DNS failure info Query [www.microsoft.com] against DNS Server 192.168.1.2, (Type = 0x1, Options = 0x10e8) returns 0x5b4 action Automated repair: Renew IP address action Releasing the current IP address... error Error releasing the current IP address: The system cannot find the file specified. info Query [www.microsoft.com] against DNS Server 192.168.1.2, (Type = 0x1, Options = 0x10e8) returns 0x5b4 info Redirecting user to support call Gateway Diagnostic Gateway info The following proxy configuration is being used by IE: Automatically Detect Settings:Enabled Automatic Configuration Script: Proxy Server: Proxy Bypass list: info Could not get proxy settings via the Automatic Proxy Configuration mechanism info This computer has the following default gateway entry(ies): 192.168.1.2 info This computer has the following IP address(es): 192.168.1.22 info The default gateway is in the same subnet as this computer info The default gateway entry is a valid unicast address info The default gateway address was resolved via ARP in 1 try(ies) info The default gateway was reached via ICMP Ping in 1 try(ies) warn Hostname www.microsoft.com could not be resolved (Error code 0x2afc).

It appears I am having DNS problems. I went into Network Connections and changed from a static IP/ DNS server to a dynamic one and I can now access the Internet. My problem is that I would rather have the static IP/DNS address. Any idea what my problem may be? Let me know if you need any more information. Thanks

is the ip address of the Linksys WRT54G wireless router 192.168.1.2?

Yes. The original problem occured when the ip address for the router was 192.168.1.1. I read that sometimes a change from that original number may fix the problem but it didn't.

Is the DNS Client service running on the PC?

I'm a little confused here as to what you have, could do - and can do now... How many PC/laptops involved; what can connect to the www; what can see/connect to other PC/laptops?
