Hi, bring your laptop to a public or friends place and see if it can login to internet. Thank you!
Your Internet Service Provider had a look yet? (LOL)
After you re-installed the new network card; did you RUN TCPoptimizer again so it can configure the new Network card?
Note: BTW, learn how to set up the TCPoptimizer customs settings based on your network speed ok! It will help to solve more problems! I have it set to open 16 connections…
Try from run command; type ncpa.cpl
what is the status of the connection, is there a red X ?
choose right click for options.
open the properties and Check to see that the IPv6 and IPv4 are enabled.
# Note: Some users have there systems setup to not use the internet; Government employees for example.
To confirm reset; open a cmd prompt in administrator;
Type; one command at a time and hit enter
netsh int ip reset c:\resetlog.txt
netsh winsock reset catalog
netsh int ipv4 reset reset.log
netsh int ipv6 reset reset.log
in the command prompt. it will take a minute to complete. then a reboot is required.
if still failed;
type:
ipconfig /all
ipconfig /release
ipconfig /renew "local area connection"
A reboot is not required
if further problems occur;
ipconfig /all
ipconfig /flushdns
ipconfig /registerdns
This will be my last entry in this post; confirm each TCPIP default key parameters...

Here is something to consider giving a try; it works in offline mode
"I am not suggesting to downlaod this version from this website, I am suggesting to read the material they provide to see if it fits you trying this method, "which I would try"; if so, I would search and download the program from a MSFT server and then have a try
http://www.ihaveapc.com/2012/04/how-to-fix-windows-troubles-on-the-go-with-microsoft-fixit-portable/You can use the Manual Reset Method found here; NOTE, it says XP, but it is good for all windows operating systems!
http://support.microsoft.com/kb/299357 (just click the area "let me fix it") you should be good to go!
Search this key in the registry:
HKLM\system\currentcontrol set\ ser vices\ tcpip6 parameters\
in the right side, is there a key that says disabled?
to re-enable IPv4 and IPv6, change it to; 0
it is better to remove the key altogether!
but, be warned... back up the key in case...
but all it does is prevent access to internet.
(MSFT, further evaluation is required to see what service it points to that actually stops this malware service)
For now, let do some general maintenance;
Disconnect the network cables first!
Disable remote connection features!
Lets do reset the firewall settings first, how about?
Right click on the network icon in the right hand corner on the desktop screen;
Click on diagnose and repair feature. Be sure log the error message here!
Right click on the network icon in the right hand corner on the desktop screen;
click on network and sharing;
lower left hand corner;
click on firewall;
then click on change settings;
tick the checkbox block all incoming;
click the advanced tab;
lower right hand corner, click restore default settings
Lets confirm a clean network system by resetting all the modems and the routers by using the reset button on each device;
Be sure to hold down the reset button for at least .20 seconds on each device while it is unplugged with no wires attached!
Then reconfigure them, PLEASE DO THIS OK!
Change the password on the router;
Changed passwords for each wireless connection, be sure to reconnect with the right passwords;
Take a look at network connections;
Are any adapters disabled? If disabled; should solved your problem by enabling them
If there enabled, continue reading;
Right click on the network icon in the right hand corner on the desktop screen;
Click network and sharing;
click manage network connections;
right click each adapter, check that each service is installed; I would, uninstall them and reinstall them at this point. I would do this to clean up the registry adapters settings. Go to device manager, uninstall any network devices including the software…
Then, I would restart the machine. Do not use the check new hardware feature here, let us be sure that the PNP feature is working correctly here too…
Check to be sure your network is setup to private...
Your TCPIP.SYS file might be corrupt, doing a SFC /TCPIP.SYS on this file will help to determine that
What is the results?
