Hi, I have become frustrated with the deadspots in my Airport network in my house using 667 Ti despite attempts fiddle with antenna as some have suggested. My house is not that big! Does anyone have experience with the Siemens "Powerline" 10/100 or USB adapters that I see advertised? Would also be useful for connecting my son's non-airport mac to network.
