In Device Manager, try disabling all other network adapters apart from the Intel Centrino Wireless-N 1030 network adapter, and test again. Right-click and disable:
- Bluetooth Device (Personal Area Network)
- Bluetooth Device (RFCOMM Protocol TDI)
- Microsoft Virtual WiFi Miniport Adapter
- Microsoft Virtual Wifi Miniport Adapter #2
- Realtek PCIe FE Family Controller
If not already, try downloading and installing the latest driver for your Intel Centrino Wireless-N 1030 adapter from the Intel website:
Download and install the driver only 'Wireless_16.11.0_Ds32.exe' or '
Wireless_16.11.0_Ds64.exe' depending on whether you have Windows 7 32-bit or 64-bit installed. Test again afterwards.
If your Windows Firewall is enabled, try disabling it temporarily, or restore the Windows Firewall to default settings, then test again afterwards. To do this, navigate to:
Start > Control Panel > Windows Firewall (or System and Security > Windows Firewall) > Turn Windows Firewall on or off.»
Start > Control Panel > Windows Firewall (or System and Security > Windows Firewall) > Restore defaults.
If you have 3rd party security software installed with a built Firewall feature, disable this temporarily and test again.
Check your Start Menu All Programs list, and the Programs and Features list (Start > Control Panel > Programs and Features). If you have any third party Bluetooth software, Wi-Fi management software, or VPN software, uninstall these, and test again.
Check to see if Internet Connection Sharing is enabled for your LAN and WLAN network adapters, and if enabled, disable it, and test again:
Network and Sharing Center > Change adapter settings > Right-click the network adapter > Properties > Sharing tab > Uncheck 'Allow other network users to connect through this computer's Internet connection' and click OK.
