Turn of the reciever from the back. Remove the rj45. If you are using a wireless bridge...then turn that off as well. Leave it off for a few seconds. Turn on the wireless bridge first. Let it fully boot up. Then plug in your rj45 and let it sit for a sec or two. Then turn on your stb.
Also, check using a computer if your internet connect is up!!
