hey,

i have a problem. internet doesn't work on my laptop. after getting some worms that prevented me to open any programs, i did a recover from previous back up. but since then my internet doesn't work (with or without cable).

wirelessly: my laptop says im connected to the router, but it says that i have no connection to internet. sometimes it says that i m connected to internet but even so when i try to open my browsers (ieplorer or firefox), it just says "unable to connect"

With wire: when i trie to connect via a cable directly to the modem, it does the same thing, it says iam connected to the modem but i have limited access, and the browsers say that it can't open internet.

i am using windows7, have a dell computer and a belkin N1 wireless router, and using cable.

i have read a few post, and tried a few solutions but nothing helped. i tried to restore the winsock using the netsh command, i used winsockxpfix, i used lspfix, i deleted my norton virus program, i reset my router to default, i deleted my cache-cookie-history from the browser, i think my driver are up to date, i check my manager device (they all work), nothing helped.

when i type the command ipconfig, it gives me:

ipv4 adress: 192.168.2.2
subnet mask: 255.255.255.0
default gateway: 192.168.2.1

when i type the "ping yahoo.com" i get:
4 received, 4 sent, 0 lost

my computer works fine and i can go online. i use wire for my computer and try the same wire to my laptop but not working. i tries another cable throught the router but still nothing.

please help.

If you are using IE as your browser: Control Panel - Internet Options - Connections tab - LAN Settings... - none of the 3 choices on that page should be selected.

(From a JohnWill post)

TCP/IP stack repair options for use with Vista or 7.

Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

While attempting to connect by ethernet and wireless please show ...

Start, Run, CMD, OK to open a command prompt:
(For Vista or 7 type CMD in the Search box after Start)

Type the following commands:

nbtstat -n

IPCONFIG /ALL

[Note that there is no space between the slash and ALL.]

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If necessary use a text file and removable media to copy the results to a computer with internet access.

I had a similar issue as this at one point...

In Windows 7 go to Control Panel > Network and Internet > Network Connections > Double Click Local Area Connection > Click the Properties Button:

You should get a list and above it it says "the connection uses the following items". From the items in the list click something that should be similar to "Internet Protocol Version 4 (TCP/IPv4)". Once you have clicked that ensure that "Obtain IP Address automatically" and "Obtain DNS Server Automatically" are ticked...

This worked for me...Good luck! :)

so, i tried the nbtstat-n ipconfig/all and right click select all and enter but it didn't do nothing.
i tried nbtstat-n (on the paste and copy below i wrote nbstat-n insteat of nbtstat-n but i already tried with nststat-n and it didn't work) ipconfig/all and enter and it said that it is not recognized as a internal or external command. all i could do was ipconfig/all and here is the result:

i don't know if there is any relation to my problem but i also noticed that my network name is: Ediway-PC_network_1 (and that where my laptop is connected to). but on my computer (desktop) it said that it is connected to network 3, and im not sure where the network 3 comes from.
well, just wanted to add this (that might be a part of the problem). tks.

It's OK that you didn't get the nbtstat -n output, 'cause I did not intend to ask for that anyhow.

The Media disconnected for the ethernet problem indicates a defective router LAN port, cable or NIC. Try another computer using the same cable and router LAN port.

Your wireless shows a good IP configuration, so try the following tests. You run these in a Command prompt window and show the results the same way you did the ipconfig /all

ping 192.168.2.2 (or whatever your IPv4 address now is)


What non-Windows security applications do, or did, you have on the machine?

ping 192.168.2.1

ping 8.8.4.4

ping yahoo.com

well today i went to the U to buy my books (going back to school monday), and tried to connect my laptop to internet over there, but it didn't work. so i guess there is something wrong with my setting and not with my router.

i also noticed that when clickiing on control panel, network and internet, network and sharing center, and change adapter setting, i have 3 connections.

one is the local area connection, the second is the wireless network connection (it shows that it is connected to the router), and the third one is wireless network connection 2 (microsofl virtual wifi miniport adapter)

i am not sure that's the third connection for. i tried to disable the wireless netwok connection (the second one), and when doing that the third connection disappears. as soon as i enable the wireless network connection, the wireless network connection 2 comes back. i also tried to disable the wireless connection 2, but even with that i still cannot go online :(

should i just reformat my laptop to its default setting just as when i bought it?

Your pings show that you have internet access and that DNS is working. So, browser(s) not working probably means a non-Windows security application mis-configured, corrupted or its data definitions out of date. Suggest that you uninstall any that you have and run the Removal Tool if one is provided.

You could try an IE Reset.

If still having problems then it likely is still some malware, or at least some corruption we haven't found, and a format of the partition and "Recover" of the system to factory defaults would be my choice. You are also welcome to visit the Virus & Other Malware Removal forum.
