Have ran a bridge between my 1522 and a DIR-615 for over a year (got both for Christmas in 2010). The 615 is connected to the cable modem upstairs and the 1522 is connected to a WD Live downstairs, for watching Netflix and Hulu on the TV.
Recently, the connection has been really shaky. I tested with a netbook connected directly to the 1522. When I pinged the 615 upstairs with 1024 packets, it responded with 1500-2000ms. When I disconnected the 1522 and used direct wireless (not moving the netbook), I got 1-3ms.
We upgraded to the recent firmware with no resolve.
Any other thoughts?
