Just a hunch, but maybe your router's LAN IP address range is too small? so maybe your subnet is oversubscribed by the time your nook color attempts to connect?
Maybe you could also reserve a local IP address for your color nooks.
or you need a firmware update?
There are two Nook Color users in my home. One of them "forgets repeatedly" that since the 1.2 upgrade, our other devices, i.e. computer and internet TV, lose connectivity (DNS Access) if the WiFi on the Nook Color is used. I have to disable the WiFi on the Nook, reset the router and devices everyday.
if you really think its a DNS issue, you could also just manually set your DNS addresses on each device, this is probably what everyone should do anyway (ie manually setting DNS addresses to a trusted source, instead of relying on your ISP -which may not be that secure).
how do you change the DNS on the Nook Color?? I've looked everywhere I can think and still can't figure it out.
Here are some interesting experiments:
- Disable DHCP serving on the problem router, and use another router or computer to provide DHCP services. Supply (via the DHCP parameters) the IP address of the problem router, along with the IP addresses of the ISP's DNS servers.
- Give the other computers on the network static IP addresses.
Unfortunately for the purposes of diagnosing this problem:
- My routers are all IPv4 only.
- I don't have this problem.
If someone has a problem router that they've replaced and consider it junk, I'd be interested in getting it and looking into this problem.
@edmannix: a downgrade is possible. Since the downgrade involves setting up a CWR boot disk to start with, you could
- make the CWR disk
- install the current manual nooter to it *and* get a copy of the Ham and Cheese APK installer, which for me has been an absolute requirement to get Titanium to run properly
- install Titanium and backup
- put the 1.0.1 downgrade/restore to stock zipfile on your NC
- run it, and immediately follow it with the prerooted 1.1 update (seriously, you can just daisy chain those two, no need to restart between them)
- on boot, skip the out of box experience and do not reregister
A rooted 1.1 device is immune from the OTA update.
If you decide to go this routeI would recommend after you do the 1.1/root applying either monster root pack or the 3.0 Autonooter, as the sideloadable root that I have is not complete.
Once rooted in 1.1 reinstall Titanium. You should be able to restore from your 1.2 backup your apps and library settings. (I have not tried it in the 1.2 > 1.1 direction, but this works in the 1.1 > 1.2 direction.)
If Titanium complains about non-market apps, it might well be worth trying to flash in the unsigned APK installer. It was written for 1.2, but if it will load on 1.1, that would probably do the trick.
If you're able to restore yourself from the Titanium backup, on reboot your device should now be correctly registered, able to use wifi as 1.1 devices were, and contain your books.
If the titanium restore can't restore apps in 1.1, it may still be able to restore data. (Probably can, actually, but as I say, the testing I remember clearly has been in preserving material going 1.1 to 1.2, where the system settings can be restored even though some system apps can not. IE: my browser bookmarks were restored; the 1.2 browser vetoes any attempt to restore in the old browser app from 1.1)
The reason to skip the registration with BN is to avoid creating a new registration token. It took me a while to figure out why my NC was being remote reset after a backup was restored, but I finally realized that a registered device has a local crypto token that's presented to BN. The token is generated during registration if it's absent. If your copy and their copy disagree, their software assumes your device is screwed up and resets it. A freshly installed NC doesn't have the token, but it can be restored from a backup.
This weekend I'm in the process of putting together some "your nook's not bricked" documentation that (hopefully) will give people pointers to a number of these things - there's a lot of overlap in things people want to try with 1.2 in particular.
I have not used bookshelves, so I can't guarantee that, either.
It's something. It's free, and it doesn't take too long to do (probably an evening if you haven't assembled the tools before.)
I agree - BN needs to be working on getting a much easier free backup utility into the shop, like yesterday. Not just because they're good people and know there's local content, but because the reset devices a couple of weeks ago.
I've asked the new community liason to try to let us know more of what happened, what's being done to prevent a re-run, and for status on either making a backup utility available or tying the shelf data to our device accounts, as well as our "what books do we own" data.
