My router is a Linksys WRT54G
wired and wirless pc's are running Win XP Pro
Laptop is an Acer 2012WLMi
I have WEP on and can connect to the internet wirlessly just fine. I can also do a ping www.google.com on the laptop and it resloves the name and pings fine.
If i try to ping penguin i get the following error:
"Ping request could not find host penguin. Please check the name and try again"
However a ping 192.168.1.101 (penguin's ip) works fine.
Both computers are on the same subnet 255.255.255.0 and have the same ip range 192.168.1.10x.

When I plug the laptop into my wired network it can resolve all names fine.

Following are the results of ipconfig /all on the laptop and wired pc

Check to make sure in your wireless connection that you have 802.1x authentication turned off.

Is it only a problem with trying to access local hosts via DNS? Are both machines running windows XP? I would see if Netbios over TCP/IP is enabled on both machines. If it isn't you can try enabling that on both machines, and then configure firewall rules denying NBT into your network and out from your network. Uses ports 137, 138 UDP, port 139 TCP. Also block port 445 into your network.

Lastly, try doing an ipconfig /flushdns and then ipconfig /registerdns on the wireless box.

Hope that helps.
 
802.1x authentication is off.
Both computers are running XP Pro.
ipconfig /flushdns and ipconfig /registerdns had no effect as far as I can tell
It is only a problem wirelessly connecting to local hosts via dns
NetBIOS over TCP/IP is enabled
Just to clarify, this is only happening with my wireless box. However, if I plug my wireless box into my switch everything works fine.
 
Strange issue. Do you have any sort of firewall/filtering on the router that might prevent your wireless connection from being recognized or block it? Are you using anything like Zone Alarm or other software firewall on your machine?

How about specifying the router's IP address as the primary DNS server, as opposed to the two references from your ISP? Usually I put one in the secondary DNS server setting, but the default gateway is usually my first server, unless there is an actual DNS server.
 
It's not DNS unless you have a local DNS server running. They would use B-Node broadcasts to look for each other. One thing you can do is just edit your hosts file If you only have a few machines it is an easy way to resolve name resolution issues and the stack hits hosts first I believe. Not that it matters, your talking miniscule fraction of a second difference but anyway, I use hosts to resolve names fairly frequenty. Windows is a notoriously bad OS for local name resolution without some server mechanism, DNS or WINS etc...
 
There are no firewalls other than the router, but that shouldn't effect internal traffic. I am basically stumped. I have been google searching most of last night and this morning. I could always do what ktwebb suggested, editing my hosts file, but the thing is that i am going up to school in 2 weeks and editing the host files for all the random machines i will be accessing up there will be a huge pain.

I also have a extra linksys wireless b router laying around but am avoiding using it because last time i used it, it kept cutting off all network traffic and I would have to restart it.
I guess the bright side is that i can still use the wireless for file sharing as long as i know the ip of the computer i am trying to reach.
 
Changing the router would have no effect because it's not part of the equation. When you go to school you'll have either DNS or WINS in place so using a hosts edit would be unecessary. Editing your hosts is a fix for your short term problem. Your just dealing with a browser war issue. Common windows problem when you are stuck with NetBIOS broadcasts to resolve names. That's a non-issue on a large network with DNS or WINS doing that for you. HOSTS is the easiest way to fix your problem at your house but {shrug} if you don't mind using the IP instead then so be it. Just pointing out your argument about having to maintain a huge hosts file at school is mute.
 
thanks for the help and info ktwebb
also thank you for the help DVAmon

I ended up just editing the hosts file. All is good now. :)

Edit: Could a fresh XP install fix this problem? The reason I ask is because I don't like the way acer partitioned this drive or the file system it is using and have been thinking about doing it anyways.
