DIR-601
Hardware A1
Firmware 1.02
Using the Network Filter page I have been able to block one LAN device, by accident (I forgot about my wireless Roku). But have not been able to block MAC addresses outside of my network. I am using the "Turn MAC filtering ON and ALLOW computers listed to access the network" selection. Did not include my desktop computer at work (not at my house) on the list but was still able to get into my network like nothing was setup. Seems pretty straight forward on how it should work and that it has been made fool proof as you turn on the feature and allow which computers access in the same step, then click Save Settings.
Btw, side note but I cannot adjust the date of the router past 2012. Is this Y2K all over again? Also, it seems to be really slow to respond after upgrading to 1.02 and now get a "Please want... The gateway is currently measuring your network connection . Accessing this web page might have an effect on the measurement. This page will refresh shortly." Getting about twice the speed I am paying for, which very much not the norm but the graph looks like an edge of the a handsaw. Thanks for any help anyone can be, ahead of your answers.
