Re: HELP... can't get it connected to my router for internet etc...

Hi, I'm new here and looking for help. I have two computers (one desktop and one laptop) and two Tivo's on a home network with a Linksys G router. THe laptop and Tivo's use the wireless part and the desktop is plugged in via a CAT5 cable from the router. I just got another desktop for me (the other is my wifes). This new computer has Windows XP with media center software (I think version 2002 but HP says it's 2005... ). I plugged the new computer into the router but I can't seem to get it to hook up to the network properly so I can get internet and file share etc. I've done the setup wizard and tried numerous other proceedures from help faq's as well as others but I can't seem to connect properly. It says it's connected but says "This connection has limited or no conectivity. You might not be able to accss the Internet or some network resources...". Now when I leave the "Internet Protocal (TCP/IP) to "Obtain an IP address automatically" it gives me the conctivity message above and assigns an IP Address of "169.254.8.143" and a Subnet Mask of "255.255.0.0". Now the other computers on my network all are set to obtain the IP automatically and they have IP Addresses of "192.168.1.101" then the next computer will be the same but 102 on the end. Then they have a Subnet Mask of "255.255.255.0" and a Default Gateway and DHCP Server of "192.168.1.1". When I manually configure the network connections IP Address and Subnet Mask to match the other computers (adding one to the last number on the IP Address) it doesn't connect at all. I can't figure this out and it's driving me crazy. I would dearly appreciate your help in this. Is there something I need to do on the main computer or am I missing something on the new computer? Do I need to change the "channel" of the network card and how do I do that and how do I check my other computer to see what channel they are on? I've tried everything I can to get it to work, including all kinds of stuff I've found on HP's website and Microsofts website but nothing seems to work. I could really use some help if anyone can help me get this to work. I really really need to get this connected so I can use my internet connection. Also, do I need to do anything on the main computer to get it to recognize the new computer or should I just be able to hook up the new computer and set it up from there? HP said something about maybe needing and "extender"??? what is this and would it help? I really need help, Looking forward to hearing from you. Tom.

What you are doing in assigning IP addresses looks good to me. The DHCP is weird, as you say, but your manual choice of 192.168.1.103 or whatever and 255.255.255.0 looks good.

At this point I suspect a firewall on the new computer is blocking your connection. I assume Windows Firewall is on by default, but configured wrong. It is also possible that settings on your router are blocking the new computer.

Besdies that, there are always ways hidden in the network setup panels to screw you up, of course, and I have no ideas beyond the firewall.

Do you know how to ping? Open a command (DOS, formerly) window and type ping 192.168.1.101 or similar. You should see four successful connects with times of a millisecond or two, but probably won't.

I would start on a 'good' computer, ping its own address as well as 127.0.0.1 (which means "me") and look. Then ping 192.168.1.1 (the router), then the other good computer, then the bad one. Repeat on each computer in turn. Try it on the bad one even if the others couldn't ping it.

Also in the command window, try the command ipconfig /all which will tell you some mysterious things, including, if you're lucky, the "Physical address" - looks like an IP address with six pairs of number in hex - this might help you get the router to allow your new box (but I doubt it - it's usually only required for wireless). It's also called MAC address (Media Access Control, not the computer from Cupertino!).

Pretty random remarks; I hope they're useful.
