Okay. I've only got experience with XP so all of my instructions will relate to that.
1. Goto your desktop pc and right click the local area connection in the taskbar then click 'open network connections'. Right click on the local area connection and click properties.
Scroll down on the list and select 'Internet Protocol (TCP/IP)' and click properties. If 'Obtain an IP address automatically' is not selected then select it and click 'OK'. If your problem still persists then we'll move on.

2. Double click the wifi connection in the taskbar (bottom right of screen)
Click the support tab then click details. Make a note of the default gateway and the dns addresses.
Type the gateway address into explorer or firefox address bar. You will be prompted for a username and password (default user:admin, pass:admin).
On my router I then click status->local network (yours may be different) to find the ip address of the local connection. It may be that it is the same as the wireless ie 192.168.1.1 but I have seen a few routers use a different one eg 192.168.0.1.

4. You now need to goto your desktop pc and right click the local area connection in the taskbar then click 'open network connections'. Right click on the local area connection and click properties.
Scroll down on the list and select 'Internet Protocol (TCP/IP)' and click properties. Now select 'Use the following IP address'. Use the ip address from the router as your default gateway (192.168.1.1 or 192.168.0.1 etc). Use a corresponding value for your ip address (just change the last number) eg 192.168.1.105. Looking at your wan ip addresses I would use a number between 103 and 150. The dns servers should be copied from your laptop.

If you still have a problem, or your settings keep being changed for your local connection then you are infected with something.



Good luck.
p.s. MSN me if you are having difficulty following the steps (click the blue man top right of all of my posts. I don't know if I can explain them any better but I will try.

It (desktop)worked after changing the ip as it connect successfully to the local area connection.
But it still cant go to any websites.Probably something wrong with the settings? It is fully connected to the network though .Not like it was having the limited or no connectivity problem previously.
What happened?#!#

i did not enter the dns . Could it be the fault? What to entered there

help anyone??

Sorry. Just got back. The above instructions will do it.

Do you still require assistance or is it all sorted now?

DNS Servers . . . . . . . . . . . : 202.156.1.78
202.156.1.68
218.186.1.88
I used these. And it still cant work.
God....

202.156.1.78 is what you reported for all the PC's earlier in the thread.

I strongly suggest you back up all your critical data and follow the PreWork link. It can do no harm but will at least reassure the likes of me it's not Malware

sorry man. The prework instructions. I followed till the download malwarebyte part when they say find update then download it. I cant connect to internet with the computer how do i update?
Thanks

Everything is using dhcp. The Modem can only handle ONE device and issues ONE IP at at time. That is the conflict, you should note at least two or all three have the same ipconfig info.

Solution is alittle hard for beginners.
ICS

One pc acts as the gateway to the internet, it has the only IP the modem issues. the others connect thru this one.

setup ICS with WindowsXP

XP ICS - Manual Server Setup - Broadband Connection

make the dns the same as the default gateway address. manually configure the entire network, IP addresses Default gateway, DNS and see if that works?

Run the Malwarebytes without the update. The downloaded version should be pretty much up to date.

(PCGuru - it's all going through a router)

true enough i delete the infections with the malwarebytes. They were removed sucessfully. But i still cant go the internet???

Please post the logs from Malwarebytes and HJT as requested in the PreWork.

The Malwarebytes program is just a part of the procees and you'll now agree you are infected.

i see...
Where do i post the logs to?
So i just need to post the log and wait for u guys to help?
Sorry i dun quite understand the prework thing

Edit: I know where to post already (Here). Sorry
