Hi Everyone

I have a problem that I simply cant get around. Its quite hard to define the problem with catchphrases to google a solution, and the strings I have used hasnt given me any fruitful results yet. So I will try here and hopefully one of you can guide me in the right direction.

Background and problem is as follows:

I used to have a Windows XP based PC that I used for work. My PC was joined to a domain with a pretty useless and strictly governed Internet access on the domain via a proxy. I had a ADSL line installed in my office, which my notebook accessed wirelessly, and I used this to browse the net and download drivers, updates, etc.

I am not very clued up on networking protocols and stuff, but my onboard wired NIC got a IP from DHCP on the domain, with its own gateway, and the Wireless NIC got a IP from the ADSL modem, with its own seperate gateway.

Our company uses McAfee Virusscan 8.7, and it worked fine with no blocks and stuff to inhibit me from using it.

I now got a new notebook, with Windows 7 Pro 64bit. I tried to get the same solution going on it, but no luck.

Before joining it to the domain, or even plugging in the wired LAN cable, I was able to connect wirelessly to the ADSL and run updates and stuff through it.

When I joined it on the domain, it picked up the domain settings and stuff in Network and Sharing Centre, and it connects to the Wireless network on the wireless NIC without conflicts and stuff, but I cant access the 'open' internet on Firefox or even in Internet Explorer if I remove the proxy settings.

If I disable the wired LAN NIC in Device Manager, I can access the internet just fine, so something happens when both network connections are active on Windows 7 that prevents me to access the Internet provided by the wireless connection.

I cant really get any answers on the net for this, cause its hard to describe it. I did however try to disable the Homegroup services in Windows 7, but this didnt resolve the issue.

Any advice would be greatly appreciated please.

It seems like you are facing a connectivity issue when using both your wired LAN connection to the domain and your wireless connection to the ADSL modem simultaneously on your Windows 7 Pro 64bit system. Let's explore some steps that might help resolve this problem:
  1. Network Priority:
    • Windows determines the priority of network connections based on the interface metric. The lower the metric value, the higher the priority. You can adjust this metric to prioritize your wireless connection over the wired LAN connection.
    []Gateway Configuration:
    • Check the routing table to ensure that the correct gateway is assigned to each network interface. Misconfiguration of the gateway settings could cause...

    ]DNS Settings:
    • Make sure the DNS settings are correctly configured for both network interfaces. Incorrect DNS settings can lead to connectivity problems.
    []Proxy Settings:
    • Ensure that the proxy settings are correctly configured. When both network connections are active, the proxy settings might be causing conflicts. Try modifying the proxy settings or disabling them temporarily to see if that resolves the issue.

    ]McAfee Virusscan:
    • McAfee Virusscan might be interfering with the network connections. Check its settings to see if there are any restrictions that could be blocking internet access. To troubleshoot further, you can try the following steps:
      • Network Adapter Priority: Adjust the network adapter priority settings in Windows.
      • Static IP Configuration: Assign static IP addresses to each network interface to prevent conflicts.
      • Network Diagnostics: Run network diagnostic tools in Windows to identify any connectivity issues.
      • Update Drivers: Make sure that the network drivers for both your wired and wireless adapters are up to date.
      • Firewall Settings: Check the firewall settings on your system and ensure they are not blocking internet access.
      By following these steps and checking the configuration of your network settings, you should be able to resolve the issue of not being able to access the internet through the wireless connection when both wired and wireless connections are active.
