SSHGuru: I too can confirm the wifi problem as well as the standard signal issue. On the GNex I get 3-4 bars on wifi inside my house. On my ancient HTC Incredible I get 5 solid bars, full strength everywhere in my house.
I sure do HOPE they can fix the radio via software. Though I dont know if Im willing to roll the dice. As it is Im also getting forced reboots on occasion, with an unrooted "top of the line" phone, minimal to no apps, have done hard resets and am tired of redoing my phone to see if erasing it all helps (it hasnt). Im totally pissed off, the hype I had behind this phone. It was supposed to be a game changer. The radio is laughable. At best they fix it with this, the second update for the device thus far. At minimum they leave it as is or give us the appearance of a stronger signal but dont really fix the problem at hand. What a conundrum. Google and Samusng totally left us out on the lerch here.
