Nook colors being unable to talk to wireless access points is a common and super-frustrating problem.
Consensus is that release 1.1 of the BN software is more reliable at connecting to access points than the newest 1.2 release at this point.
If you've tried everything else, you can reinitialize your NC, install 1.1, and lock it from further updates by rooting it.
So ask for those instructions, but only if you need them. Before you go there, be sure you have to.
Let's start with known incompatible or borderline compatible access points for software 1.2. If you have one of these, roll back and root. That is the only fix.
This applies to at least three consumer routers: DLink DL-624, Westell 327W and Belkin F5D8231-4. There is an unreleased fix for the Belkin, no info on the Dlink or Westell.
Each of these three worked fine with Nook software release 1.1. Go install it.
Assuming you don't have a known bad router, try these steps:
First, try the obvious: hold the power button on your NC in > 15 seconds. Ignore the "do you want to shut down?" dialog. Your NC will power down. Power back on. This process resets some components, and some folks find it helpful. I include it here, but I realize you probably already tried it. More than once.
Now to some troubleshooting.
1) find out what router or access point model you have, and what software it is running. If an update is available from the manufacture, install it and see if your NC can connect after you reboot both devices.
2) Once your router is up-to-date, try this, making each of these changes together:
- tell your router to run in G only or G/N if you'd immediately kill services you need by disabling N.
- Disable MAC filtering
- Disable WEP and WPA
- Put speed in "auto" and channel in "auto" rather than manually setting either
- Broadcast your SSID
- Try setting your lease time to a very long interval - 1 week if possible
If you make those changes you may well be able to connect. Then you can start walking the changes back one at a time.
On the N band setting, you may not be able to "lock" the router at its highest speed or anything close to it under 1.2. You may not be able to use N at all (some Cisco access points in N just don't work with NCs running N, but do work with NCs running G.)
Most folks are ultimately able to hide SSID, use WPA and MAC filtering all without problems.
If you still can't connect, you can look into doing a full clean install of 1.2 (if you really like it), and if that fails, install 1.1 and then root.
Some people are able to get connectivity after a full format and reinstall of 1.2 Some are not.
If you are unable to connect your 1.2 to your access point after
- updating your AP software
- doing a clean install of 1.2
- turning off the bells and whistles on your router,
please let BN know that you followed this guide and could not establish a connection. Please also give them the model # of your router or access point.
BN doesn't have a copy of every AP in the universe and right now I think it makes sense to help them identify problem models. APs are commodity hardware. Most run one of a relatively few Linux kernels and a relatively few wireless and ethernet chipsets. The more problem routers BN knows to test, the sooner they'll find a pattern.
