I am trying to network my desktop and laptop using a linksys wireless-g 2.4ghz 802.11g broadband router
with out much luck.
I have set the router up and so both items have internet access, but i can't seem to get them to network.
Both computers are running windows xp home with sp2 , i have run the network setup wizard on both and disabled the windows fire wall on both. when i go in to "my network places "on the desktop which i am using as the host and click on "view work group computers" it shows both of them, but when i click on the laptop icon i get a message "laptop is not accessible.you might not have permission to use this resource. contact the administrator of the server to find out if you have access permission. the network path was not found."
when i go in to "my network places" on the laptop i get nearly the same message except it says "the list of servers for this work group is not currently available" also there are no icons for either computer shown here.
I have pinged both computers and got 100% loss on both. The ip 's are 192.168.1.103 for the desk top and
192.168.1.104 for the laptop they both have subnet 255.255.255.0 and both have default gateway 192.168.1.1
I have tried to give as much information as i can here but if you need to know anything else i'll gladly get it.
any help will be greatly appreciated.

regards Felix
p.s i am a relative novice at this so its step by step if possible, thanks again.

A couple of quick comments:

You should have firewalls set up on both systems, turn off the Windows firewall and use the one in your anti-virus software. If that does not have one, download and install Sygate, Kerio or ZoneAlarm. You may have to do some experimentation which will work best with your system. Only run one firewall at any time. You can find links here: Recommended Freeware
- you will have to do some tweaking (e.g. enter your LAN adress range in the permissions list) to get the network working but you will be better protected from outside attacks.

Check you have both systems on the exact same workgroup name.

You have wireless NICs in both PCs (obviously), did you configure them as peer-to-peer or for WAP use? Does the wireless software show you what connections it has available and are both PCs connecting to the same network?

Are those static IPs you configured or just what you're seeing at the moment?

:thumbsup:

Have you enabled file and printer sharing? You will need to set the permissions for each file, by right clicking the folder/drive then select sharing and enabling the level of sharing you desire. I do not recommend sharing whole drives. The shared folder is plenty.
For a wireless network I would password protect what I share. It's a pain but if some neighbor taps your system, they will have unrestricted access to your computers without passwords.

Thanks for your replies guys
Hi acklan
I had enabled printer and file sharing i have also password protected
the network( which i have now disconnected)
i am grateful for your time and help
thanks alot felix


Greetings Rimmer
thanks for your time,
i had only turned off the windows fire wall and left the overs running
that is norton onthe laptop and sygate on the desktop .
as for the IP's i checked the "obtain an ip automatically" box as the instructions said as i am using a DHCP connection, the work group name is exactly the same on both, and i'v tried peer to peer and wap
i am going to have another look at the fire walls the problem may be there, also it has now started to try and connect through dial up,
which is something that i have done while i'v been try to sort this out.
so i have disconnected it for a while.

thanks again felix

From a command prompt, run ipconfig /all to check the ip addresses of both PCs and the gateway.
At each PC, at a command prompt, ping the gateway and then the other PC e.g. ping 192.168.1.1
Then temporarily disconnect the router from the internet and turn off the ani-virus and firewalls on both PCs.
Do the pings again.
At the command prompt type ipconfig /release then ipconfig /renew then recheck the ip addresses and try the pings again.
If there is no difference I'd be looking at the firewall settings on the router... maybe?

You don't need to worry about the 192.168.x.x addresses because these are for your (and everybody else's) local LAN only. The router IP I'm not sure about, better put in some xxx for safety.

Nah! It's all too much for me...

There is a Microsoft article describing that Teredo stuff here.

Here is an extract -

Summary

Teredo is an address assignment and host-to-host automatic tunneling technology that provides unicast IPv6 connectivity when IPv6/IPv4 hosts are located behind one or multiple IPv4 NATs. Teredo tunneled packets are sent as IPv4 UDP messages. Teredo communication is facilitated by Teredo servers and Teredo relays. A Teredo host-specific relay is an IPv6/IPv4 that does not use Teredo addresses, but can communicate with Teredo clients without having to use a Teredo relay in the communication path. There are defined processes for obtaining a Teredo address, maintaining a NAT mapping, and performing initial communications between Teredo clients, Teredo host-specific relays, and IPv6-only hosts. The initial communication process in each case depends on whether the Teredo client is located behind a cone or restricted NAT.


- are you sorry you asked yet? :thumbsup:

I only know about simple things like 'ping' and 'DIR'.... *sigh*

Did you do the ipconfig /all on the other machine? Was there anything different?
Did you do the pings? What were the results? (roughly)

I had the exact same problem with my desktop and laptop. Try using the Easy Connect at linksys.com. Hopefully, that will take care of your problem.

If you don't know what port forwarding is your probibly don't need it. Are you port forwarding games, or connected at work?

To all you guy, who got problem with this Tunnel whatever. While ago I got the same problem with your, and I go to google surf to find an answer. I didn't find any answer to my problem at all. So I sit back and think. What is went wrong? How come yesterday I still be able to access the network files and printer, but how come I can't access it now? I though I got someone hack in my computer, and try to scan virus everything. Well, of course nothing show up. So I keep thinking what I just did and created this kind the problem. So I remember I just install a Sygate Pro Personal Firewall on COMPUTER 1. The problem is not on COMPUTER 1, but it is on COMPUTER 2. The COMP 1 still able to access sharing files on COMP 2, but the COMP 2 can not access the files sharing on COMP 1. Alot people saw the problem on COMP 2 would though something wrong with COMP 2, and plus it show the Tunnel thing when we use command prompt IPCONFIG right? But it doesn't show in IPCONFIG on COMP1.

Therefore, I think it must be something block the access COMP2 to COMP1. The only thing could block the access from network and internet is FIREWALL right? That why, I go to my COMPUTER 1, which I just install Sygate Firewall. I went to the SYGATE FIREWALL OPTION, NETWORKING TAB. I saw there is 2 things on it, but only 1 thing is selected. This 2 things said something like this:

1. ALLOW OTHER TO BROWSE MY SHARE FILE AND PRINTER. (Which is selected )

2. ALLOW OTHER TO USE MY SHARING FILE AND PRINTER. (Which is NOT SELECTED)

That why, I select the 2nd as well, and the problem solve. I hope this post we help you guy, who ran into this kind of problem. Good luck.


P.S. I register to this forum just to post this answer to help you guy. I'm an admin of one forum. :D
