I am connected to the wireless modem in my laptop, but it says there is no internet access.
I have full signal strength but no internet. Ethernet and wireless both are not working.
I tried to renew IP address in comand promt and I received following results.

Good advice Drew.

You might want to make sure these services are started

Go t Start > Run, and type services.msc.

Scroll down until you see the 2 WLAN entries and make sure both are started.

Thanks for the advice drew.
I've tried both. Power cycled the modem and then the router and also uninstalled both adapters.
The problem still exists. Internet still doesn't work.

Thanks for the reply.
I checked the WLAN entries and they were already started.
I restarted them but still no internet.

139 ms is a long time. mine were between 39 and 56.

Did you try resetting the modem

Did this start immediately after install?

It seems DNS is not resolving. Try this:

Google
 


#10
Yeah i reset modem and now it's 83 to 90 ms.
I installed windows 7 about two weeks ago and internet always worked.
Somehow after last night it stopped working.
 


#11
What should i do to resolve dns?
 


#12
try to set your DNS server to 4.2.2.4 .. its a public DNS server, it should work on every connection
 


#13
Can u tell me how to do the right way?

Hello again,.
Try going to Start > Run, and type cmd. Now type msconfig /all.

Copy all that information into Notepad and attach It to your next post.
 


#15
When I try that it brings up a system configuration menu with "general, boot, services, startup, and tools" tabs. At the bottom, when I click on apply and then OK, it reboots the computer.

This is a probably a long shot but it sometimes resolves poor connection issues... and it's easy to reverse.

go to Task Manager /services /services and Disabled the Function Discovery Resource Publication service

(don't disable the other Function Discovery service) reboot and test

Note: Windows 7's new "HomeGroup" connectivity requires this service.

I installed the drivers. But, it still doesn't work.
