|the reason for having them both in case one of them packs in, which it has!|
Ok, well, where I work we have a lot of laptops and all are wireless capable. Everytime some user decides to enable both the wired NIC and the wireless NIC at the same time the laptops start having major connectivity issues.
To fix this, we disable the wireless (not needed when you're connected via a network cable) and they work just fine.
I suggest to you that you disable the wireless and see if the wired NIC doesn't start working correctly. If it does, leave everything alone.
In the future if the wired NIC screws up it's a simple matter to enable the wireless NIC, disable the wired and start using the wireless network.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
