Often on a public network you need to go to the home page on a browser & OK their T&C's did you do this? I know on my mobile I need to do this at Starbucks etc.
All the Nook can do is connect to a wireless access point. Internet connectivity is between the access point and the router, or the router and the service provider.
You may also have issues if you connect to an older Wireless N access point - companies started selling them 2 years before there was a real standard, so there can be problems. If you have to install software on your PC to use your wireless - not if it's recommended, if you actually can't connect properly without additional software - then likely this is you. There should be a firmware upgrade available for any access point like that, and you should install it. Usually in this situation your Nook would say it was connected and then disconnect, but with non-standard equipment anything can happen.
Colfrank, Make sure you are running SW version 1.1.0. **go to settings, Device info, My Nookcolor.
DHCP is set for about 7 days
Yes, running v1.1.0 on Nook Color
My old version Nook (v1.5) has been connected to my router for two days now with no
drop outs or connection resets needed. WiFi/Web seems to be fine.
I've used my NC to connect to multiple WiFi spots and have not had a problem. Recently, I made my android phone a hotspot and have not had problems with this either. Home network is without problems as far as NC is concerned. But whenever I change a WiFi spot I have to go to settings, wireless and wait for the connection, maybe 30 secs and then I'm connected.
For those having problems connecting at home, but not other spots, I would suggest a call to CS for your router. I have found them to be very helpful in adjusting settings and connecting new devices. If this does not work, then replace your router for a newer one. Usually you get free tech help for a year. I know this can get expensive, but in the long run, you'll save on time and headaches.
I read all these comments about resetting routers, turning on/off security and the like.
When you are travelling.... you do not have these choices.
THE ISSUE is that Nook Color WiFi has some connection problems.
Last night I was in an ER (a visitor), my Nook Color had a non-secured WiFi signal, at 54mps,
excellent signal strength.......... "Connected, but no Internet..."
Same thing in many other locations, including my own home sometimes.
B&N people.... you have a problem !!
When the NC connects to your WiFI (any WiFi hotspot), it then tries to go to an internet address (I don't know which one, probably www.barnesandnoble.com) and if it can't get there, presumes there is no internet connection.
That can happen for several reasons. First one being, some WiFi hotspots require you to sign in before you can get beyond the router onto the internet. To test this, once your WiFi connects, try to open any webpage. If you get a sign-in page (or accept T&C or whatever) and then acknowledge it (sign in or accept T&C) now try the internet.
The next most common reason is that the NC is not getting the name of the DNS servers (things that translate domain names "www.barnesandnoble.com into a phyiscal IP address) when it gets it's IP address from the WiFi's dhcp server. You can "test" this by manually setting the DNS servers to 18.104.22.168 and 22.214.171.124 (both are google public DNS servers). If that fixes the problem, then you need to check your router (dhcp server) and make sure it is properly passing on the DNS server IPs to the NC. You'll have to check with your router manufacturer (web site) for exact details on how to do that.
Another issue is that the B&N website is down temporairly. That should be a rare occurance, and even rarer would be if your WiFi router isn't connected to the internet at all. The (hopefully) obvious test for that would be if other devices on your WiFI can get onto the internet.
There are other problems that can cause this issue...but the list above would cover 99.9% of all cases.
Obviously, I can't speak for YOUR particular NC or YOUR particular WiFi setup, but I can say that MY NC has never had a problem connecting to ANY WiFi hotspot I've tried and then connecting to the internet.
