is his tcp/ip stack up?  can he ping you?  is your router blocking ICMP packets?

Just go to the command prompt (on windows XP just type CMD on the START > RUN) and type ping website.com . you will get the IP address. or You can go to dnsstuff.com which can do a whole lot of other things than just getting the IP address.

If you are using Windows XP.  Open Control Panel.  Open Network Connections.  You should see an icon for Local Area Connection.  Right click on it and go to properties.  Choose Internet Protocol (TCP/IP) and then Properties box.   If it is checked to obtain IP address automatically then try the following. \n\nOnce you right click on the icon for Local Area Connection, click on Status and then the Support tab.  If you see an Ip address beginning with 169.254.x.x. (the x stands for numbers) then your system is not getting an address from the router.

enable Mac address authentication, this will display the names of the devices connected to your Wi Fi, then just select the devices you want to  access your WiFi.\nNetgear 192.168.1.1\nLinksys  192.168.1.2

Yes, login to the router.  There should be section that shows the IP addresses of connected computers.  Although, if I remember correctly this only works when using DHCP (Dynamic Host Configuration Protocol) which auto-assigns computers connecting to the network an IP address.

your connection string should stay close to the same. the difference should be instead of c:/... it would be the machine address or name. also you would include the login/pass with the connection string. its very simple. link below help with connection strings

By MAC addresses you mean IP addresses.  MAC addresses are the numbers uniquely identifying the network card and are burned into that cards firmware.\n\nHave you fully explored the menus on your Linksys?  I never saw one that couldn't be configured.  You would not configure the addresses for each computer on the router per se.  You would modify which range of IP addresses are handed out for dynamic machines.  So instead of "Start handing out IP addresses at 192.168.1.2 and up" set it so it gives them out at 192.168.1.10 and up.  (Just in case your friend brings over their laptop and wants to plug in.  The DHCP server is still there for him.)  \n\nThen on each computer you don't want the IP address changing on, set the IP address as static and assign it using the numbers excluded from your DHCP sever range.\n\n192.168.1.1 --Router\n192.168.1.2 --Redhat Box\n192.168.1.3 --WindowsBox\n192.168.1.10 --Dynamic\n...

Click settings in the start menu.  There should be a place somewhere in here for connections, network, or something like that.  Try those and one should have a page that shows you the current IP address.  I don't know what version of pocket pc you are running so I can't be extremely specific.

It mean some other computer on the network has the exact same address as your computer.  Contact your Network Admin so he can you give another IP address for your computer.

i'm sorry i am not sure how to find the IP adrdess, but just for your info, your IP address changes, what you should be looking for is the MAC address, which is fixed. peace :)

ignore ALL the people above\n\nlog in to your router (check the manual on how to do this)\n\nthen look for a option which shows you how many MAC numbers are logged into and using the router.\n\nFirst find out ur own MAC number by the following method:\nClick "Start", choose "Run...", type CMD and click OK, then type ipconfig /all in the Command Prompt window that appears. The number under physical address is the MAC address. If multiple IP are displayed, you should look under the label "Ethernet adapter x", where x is the name of your connection (which is Local Area Connection by default).\n\n----\n\nIf you see more than one MAC address that isnt urs then it means that someone else is using ur wireless service.\nYou can block others from accessing your router if you set your router to be a secure connection by using WEP. Again, check your router manual for this.\n\n\nHope this helps\n\nPS: MAC numbers are fixed. IP addresses can change every time you can log in to your router. This is the reason why i say that look for particular MAC numbers

Try logging on to the router, checking the WAN status. Also try cloning the MAC from the cable modem. Some providers won't let a router connect, so you have to fool them into believing that the router's the cable modem. Make sure that the modem has a solid connection to the coax. Check the physical connections between the router and the modem, make sure the network cable is plugged into the WAN port of the router. If you don't have an IP address under WAN status, then you're router is not connecting to the modem correctly. If you can't log into the router, then you've got problems with your computer.

To find the mac address for any pc go to Start- run and type cmd then click on ok.\n\nIn the black DOS box type ipconfig /all and hit return.\n\nShould see something like this.\n\nMicrosoft Windows 2000 [Version 5.00.2195]\n(C) Copyright 1985-2000 Microsoft Corp.\n\nC:&#92;Documents and Settings&#92;Administrator>ipconfig /all\n\nWindows 2000 IP Configuration\n\n        Host Name . . . . . . . . . . . . : laptop2\n        Primary DNS Suffix  . . . . . . . :\n        Node Type . . . . . . . . . . . . : Hybrid\n        IP Routing Enabled. . . . . . . . : No\n        WINS Proxy Enabled. . . . . . . . : No\n\nEthernet adapter Local Area Connection:\n\n        Connection-specific DNS Suffix  . :\n        Description . . . . . . . . . . . : 3Com 3C920 Integrated Fast Ethernet\nController (3C905C-TX Compatible)\n        Physical Address. . . . . . . . . : 00-0B-DD-DC-DD-F4\n        DHCP Enabled. . . . . . . . . . . : Yes\n        Autoconfiguration Enabled . . . . : Yes\n        IP Address. . . . . . . . . . . . : 192.168.0.3\n        Subnet Mask . . . . . . . . . . . : 255.255.255.0\n        Default Gateway . . . . . . . . . : 192.168.0.1\n        DHCP Server . . . . . . . . . . . : 192.168.0.1\n\n\nC:&#92;Documents and Settings&#92;Administrator>\n\nThe infomation displayed will be your IP address, subnet etc the number you want is the physical address which will look something like 00-0B-DB-DC-D0-F4 in the bit that says ethernet or wireless adapter Local Area Connection, this is a unique number givven to every network adapter card, Ethernet or Wireless.\n\nRegards\n\nRob

Go to system32 folder->drivers->etc and open a file called hosts. This file might have www.cnet.com 127.0.0.0 as an entry. Delete that. It might work. And dont forgetto make the file readonly. This worked on windows 2000 fr me.

The Ping command just tells you whether a certain IP address is responding or not. It will not retrieve the MAC for you. Arp can be used to retrive MACs for you. But only of the current "workgroup". MAC addresses are irrelevant after the first hop. Thereafter only IP addresses are relevant. Hence, you can never retrieve MAC addresses of any nodes beyond the first hop. For this reason, MAC addresses arent even transmitted beyond the first hop.

If they are both on the same workgroup, try pinging each other. If you get succesfull ping then you probably have settings the wrong way on the permissions. Right click on my network places and click the link that says view workgroup computers. You should be able to see both of them there. Make sure you have the cdrive shared and with full permissions to network users. Also try going to start - run and type &#92;&#92;192.168.-.- (whatever the ipaddrss of the other machine is) and see if you have access. If you get the "not enough permission error" then you are missing something.\n\nGood Luck.

Since you said you could connect to your neighbor's network, I'm assuming you have a wireless network. \nOn the computer that won't connect:\n1. Distance/interference?\n2. Any firewalls?\nOn the router:\n1. Any MAC or packet filters?\n2. Updated Drivers?
