New D-Link Modem/router connected but no internet access
My desktop recently broke so i bought my first laptop. I have AT&T DSL and i bought a new D-Link DSL-2640B modem/router so i could have wireless internet. I called for help on installing it and i was able to use it with the ethernet cable, however when i tried to use wifi, it worked for only about 2 minutes before it disconnected.. Now when i try again it says that it is connected (full 5 bars) but it also says there is no internet access and i cannot use the internet. I need help fixing this problem.

Also, before, with the old modem i was able to just connect the ethernet cable to the laptop and just start using the internet. Now i have to connect by putting in my username and password provided by my ISP almost like if it was dial up. I don't know why i have to do this now but not before.

please help, thank you

May we see:

Check your Services are Started on all PCs:
• COM+ Event System (for WZC issues)
• Computer Browser (computer browser will start when needed)
• DHCP Client
• DNS Client
• Network Connections
• Network Location Awareness
• Remote Procedure Call (RPC)
• Server
• TCP/IP Netbios helper
• Wireless Zero Configuration (XP wireless configurations)
• WLAN AutoConfig (Vista wireless configurations)
• Workstation

Note: You can check the services in Control Panel, Administrative Tools, Services.

All of these services should be started, and their startup type should be automatic
If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running. Checking the event log is also a good idea here, there may be clues to what is failing.

Wifi test exe. Hint from Johnwill

Download and run Xirrus Wi-Fi Inspecto from
on the problem machine. Post a screen shot of the main screen here.

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to the forum, open the full reply window and use the Manage Attachments button
to upload it here.

Note that this application requires NET Framework to run. If you get an error about a missing function, download and install NET Framework.

Before you probably had a modem/router with the router's WAN properly configured (I'm guessing PPPoE and account/password). You now have to make sure that your new modem/router is not in bypass mode (acting as modem only) and configure the router's WAN section appropriately.
