It still shows"101code".I check the help page:
https://www.entourageedge.com/suppor...kbarticleid=98

it shows that:
"101:Make sure you have a valid Internet connection. Navigate to a website you have not visited. If you have a valid connection but this problem persists, you must use a different wireless network. "

But my Edge can brower the web pages perfectly. I have tried many times,many cities in China.but my update did finally work.It's a way to update manually rather than through the update now button?

Look forward to your help.
