I've had this bad boy about 3/4 days now. Coming from DX. My signal at home and work was sub par. As time went on signal at work got better with the DX. Now with the GN I'm back to a little below sub par. I get two 3g bars than drop to none. Was roaming in a 4g area wasn't even getting 4g....wife got the D4 and has told me how great her signal is. Shes been getting 4g in 4g areas. Like the DX will this thing get better? And what is all this radio talk?
