soooo, i upgraded everything from my old linksys wrt54g and "G" adapters... any idea why my signal strength is "very low" all the time? i have everything in the same place as before. i am using the DIR-655 router with the DWA- 556 adapter. i have the latest firmware and drivers.... i have not set any security b/c i dont think the signal would even connect if i did. it appears to be using channel 1, i do not see anywhere to change then within the card properties. anyone else experience this? speed says 300mbps. kinda frustrating, i was expecting much BETTER performance, not much WORSE.
