After installing a new AT&T gateway I started having wireless connectivity problems with my HL-5370.  The printer will install and work well for about 24 hours then all LED's start flashing and it looses connection with the network.  Can't ping it's IP address.  I can turn the printer off, and then back on and all is fine for another 24 hours and it does it again.
It works fine as a network printer if I hardwire to router with ethernet cable. I have set a static IP address for the printer. Any ideas would be appreciated.
