How do i configure my ip address manually for 2nd computer that does not access internet through 2wire router? I'm a novice and don't get too deep on troubleshooting.
It is connected to 2wire router, which works fine and accesses internet (1st computer works fine). Firewall is off. Problem started after Malware was located and eradicated. It was working fine before that. XP Pro being used now - HP Computer.

- 1st (working) computer:
Connection-specific DNS suffix:gateway.2wire.net
IP address: 192.168.1.65
Subnet Mask: 255.255.255.0
Default gateway: 192.168.1.254
2nd (not working)computer:
Connection-specific DNS suffix:gateway.2wire.net
IP address: 192.168.1.64
Subnet Mask: 255.255.255.0
Default gateway: 192.168.1.254Jun 28, 2009
- Ping results for both 192.168.1.254 & 74.125.45.100 were the same:
Destination host unreachable.

Do I still need to reinstall network driver on 2nd computer? If so, how?Jun 28, 2009
- Network Adaptors:
1394 Net Adaptor
Realtek RTL8139 Family PCI Fast Ethernet NIC
No yellow exclamation points next to them.
SM Bus Controller does have exclamation point next to it though.
I have turned off Windows Firewall
I have Spyzooka 2.5 for Malware and such (don't believe it has a firewall).
I tried to load Trend Micro's firewall / anti-virus in it (have it in 1st comp), but the copy did not work. I uninstalled it. I don't think its still in there.
No other firewalls (I know of).Jun 28, 2009
- 2nd computer worked before the Malware issue.
2nd computer is only 4 feet from router with a six foot ethernet cable.Jun 28, 2009
- Yes - hardwired.
When I run network diagnostics (2nd computer) the following FAIL:
Default IP Gateway=192.168.1.254(same subset)
DHCP server=192.168.1.254
DNS server searchorder=192.168.1.254
IP address=192.168.1.254
Jun 28, 2009
- No. Both computers are hardwired (Ethernet) to the 2wire unit.Jun 28, 2009
- 2nd computer Tracert:
Destination host unreachable.
Trace complete.
1st computer Tracert:
11 attempts (and still trying) = * * * Request timed outJun 28, 2009
- I can ping computer 2 from computer 1 but not vice versa. Sorry if I didn't communicate that correctly.
Jun 28, 2009
- I have two network connections: 1394 connection & Local Area Connecton 2. The 1394 seems to be connected, while the LAC2 has an exclamation point next to it. Both computers (1&2) have both 1394 and a LAC (Computer 2 has LAC2). On Computer 1, both are connected.
On computer 2, TCP/IP "show icon notification" was not ticked, so I marked it. The "notify me..." was ticked.
Computer 2 is already set to "obtain automatically..."
* Note: On Computer 2, Icon for both 1394 and LAC2 show up in tray, and LAC2 still has exclamation point.Jun 28, 2009
- Manually configuring the LAC settings on computer 2 made the connection (no more exclamation point), but it gave a warning that there is an address confliction with another system on the network.
I ping'd both sets of numbers that you gave me, and they both came back: Destination host unreachable. Both sent 4 packets and lost 4 packets (100% loss). No windows were open and I tried it twice.
Afterwards, I ran the help and support center. It gave an error only under the IP address (192.168.1.254) - Destination host unreachable. Jun 29, 2009
- I changed the IP as requested. The exclamation point went away...appears to be communicating.
Upon pinging it, it still said, "destination host unreachable."
Seem like we're getting closer. :)Jun 29, 2009
- For some reason, I think it is the DHCP. How do you turn it on (if its off) ?
Thanks again for your diligence. This has been very trying.

Start, Run, type services.msc and then hit Enter. New window with list of services will pop up. One of them is DHCP Client. Double click it and if it's Disabled or Manual put it on Automatic. Then you can go back to LAC properties and put IP, gateway and DNS settings to automatic.

I still don't understand why you can't ping router. Here are some general advices: 1. Check that ethernet cable is not damaged. Try to connect 2nd computer to router with 1st computer's cable. Also try to connect some different port on router 2. Do you remember what malware was on this computer? Maybe it damaged some system files or some Windows services are turned off (like DHCP) 3. You can temporary disable 1394 network connection (right click and then Disable) to see if it will help 4. You can right click on LAC and select Repair to see if it will help 5. You can reinstall network card ... 99. You can always reinstall Windows if nothing helps :-(

Give to 2nd computer some other IP address, say 192.168.1.99 to resolve conflict and try pinging again
Posted by pbenke on Jun 28, 2009
Try to put LAC settings for 2nd computer on manual: enter IP adress,
mask should be 255.255.255.0 and as gateway put the IP address of
router 192.168.1.254. DNS you can leave empty for now. Close all those windows and try ping 192.168.1.254 and ping 74.125.45.100

Check how many network connections you have on 2nd computer. Either find Network Connections under Start menu or go to Control Panel and Network Connections. Is there only one connection named Local Area Connection? If it's true, right click then go to Properties. Make sure TCP/IP, "Show Icon Notification..." and "Notify Me..." are ticked. Next, click on TCP/IP and then Properties. New window opens up. Is there all set to "obtain automatically"?

At this moment I don't understand how you can ping 1st computer from 2nd one but you can't do the tracert...
Posted by pbenke on Jun 28, 2009
Hrmpf, okay :-) it's interesting that you can ping 1st computer from 2nd one and it should go over router... Can you please again run cmd and do tracert 192.168.1.65 from 2nd computer and also tracert 192.168.1.64 from 1st one?
Posted by pbenke on Jun 28, 2009
But 1st computer have wireless connection with router?
Posted by pbenke on Jun 28, 2009
Ah, 2nd computer have wired connection with router?
Posted by pbenke on Jun 28, 2009
Can it be that 2nd computer is too far from router?
Posted by pbenke on Jun 28, 2009
It really sounds like 2nd computer is firewalled or network card is not working properly. Are you sure that you don't have 3rd party firewall active on 2nd computer? What network adapter 2nd computer have anyway? Can you go to Device Manager (Control Panel, System, Hardware) and check if network adapter have yellow exclamation sign next to the icon? Tell me the name of network adapter shown in Device manager...
Posted by pbenke on Jun 28, 2009
Hm, can you ping 1st computer from 2nd one? ping 192.168.1.65 If you can't can you try to reinstall network driver on 2nd computer and see if it will help...
Posted by pbenke on Jun 28, 2009
Can you run cmd again please and do ping 192.168.1.254 and ping 74.125.45.100 from 2nd computer?
Posted by pbenke on Jun 27, 2009
Go to 1st computer, click on Run, type cmd and press Enter. Type ipconfig, press Enter and copy and paster results here. Do the same with 2nd computer
