Hi, My hardwired Ethernet card will not connect to the internet when using my wireless router. Currently, to resolve this: 1) the Ethernet Card must be disabled; 2) the Wireless card must then be enabled; then, 3) once the Wireless card has found the internet, it (the Wireless card) must be disabled, and finally, 4) the Ethernet card must be re-enabled (at which point it can then be used to access the net). Please note: 1) I have tried this with two different Ethernet cards (different brands) so it almost certainly cannot be either their hardware or software. 2) A second computer (laptop) can connect directly to internet through a hardwired connection to the router. Therefore, it is not the router. (The laptop is also Win 7, but DID NOT install the latest updates.) 3) This is a dual boot system: Win 7 and XP. Under XP, the hardwired connection works flawlessly. 4) The Ethernet/Hardwired connection worked under Win 7 for about a week, then the above problem arose on the Wednesday morning after Patch Tuesday (Automatic Updates ON) 03-17-10. System Specs: OS: Win 7 Home Premium. Ethernet: Marvell Yukon 88E8039. Wireless Card: Broadcom 802.11g Network Adapter. Router: Netgear Wireless-N 150. All have latest drivers. Many thanks to anyone who may have insight into this rather esoteric problem.
