Nexus 10 cannot sign into Google Accounts I have a brand new Nexus 10.  It worked for a few minutes of web browsing and then I am not sure what I did but somehow it got to the point where I was asked to sign into a Google Account.  Since I use gmail, the required answer to the question: do you use Google Accounts? is yes.  So I touched 'yes'.

I put in my gmail address and password.  Now it shows Couldn't sign in, Can't establish a reliable connection to the server.  There is the suggestion that it is a temporary problem but retries have failed over several days.  

I then wiped all user data using instructions I found on the internet.  However, it still ends up stuck on the screen that shows Couldn't sign in, Can't establish a reliable connection to the server.

I even logged out of gmail on my laptop, but it doesn't help the situation on the Nexus 10.  The Nexus 10 is a brick so now I am shopping for a few hundred thousand of these and some mortar. 

Additional info: I use 2-step verification on the laptop for my gmail.
I reconfigured the router to resolve the problem.  The settings that work include:


g rather than the other options being b and g/n.  This looks like the setting for the suffix on 802.11.
WPA-Personal
AES


Of course other settings may also work and might be more secure but I did not try them.
