I have problem with N mode. On old software one computer was connecting with router with 65 Mb/s speed and second one with 130-150 Mb/s. Now after flashing with Tomato my computer connects with router with 150 Mb/s speed but the second one only 54 Mb/s. I updated drivers of Network Card but it's still 54 Mb/s. How can I change in router?
