I have downloaded the latest drivers. I had been using a D-link DI-524 wireless router before I got the new DIR-615 and it would run at 54mbps before it started dropping the connection and I stopped using it. My wired connections show 100mbps. Do you think its the card (DWL-G510)or the new router? I've tried all the ideas listed in other postings about slow speed. Using the Network Magic speed test I am getting 7000kbps download and 3300kbps upload on the wireless. Getting 12,000kbps download and 3300 upload on a wired computer. Any ideas would be appreciated
