I am new to SevenForums. I have been googling a issue I am having and came accross the forum.
Sounds to be a very similar issue as you describe.
I have a Broadcom 802.11g Wireless NIC using suggested windows drivers
. Most of the time I can connect to the Wireless network with no troubles, internet works fine with good speed etc.
My issue is that sometimes out the network connection will have limited connectivity. If I disconnect from the Network and try to re-connect to the network I keep getting message that Windows is unable to connect to the wireless network. Running throught the troubleshooter suggests that I need to reset the router, which I know is not the problem becuase my other computer running XP connects fine.
I have tried the obvoious things. Restart the computer. Uninstall the NIC and re-install. Tried different drivers. Reset the router.
I don't think the NIC is faulty as it works sometimes.
What is even more bizarre, if I leave it for a couple of hours and check again the connection will be fully restored.
I have spent hours trying to get to the bottom of this, but no luck.
Any help would be appreciated.
