I recently reinstalled my old motherboard P5W DH Deluxe Chipset 975X Southbridge ICH7R. I have two internet connections one of cable internet and the other of DSL Internet. This motherboard has two built in giagabit connections namely Marvell Yukon 88E8053 PCI-E Gigabit Controllers. Both the giogabit adaptors show connection light but only one lets the internet come through on which I have installed the cable internet connection. To get the DSL connection going I recently purchased D-Link DGE-528T Gigabit Ethernet Adaptor. It installed beautifully,Windows Seven picked up the drivers. I then also installed the updated drivers from the D-Link Website. However the next day I find that there is no link and no connectivity light on this D-Link Adaptor. It is still be recognised by Windows and it says that it is functional. But there is no link no activity at all and I cannot use DSL connection. I have heard that there are problems in Windows when using two Gigabit adaptors. May I be advised if there is a solution in getting the D-Link adaptor going or I should return it back to the retailer.
