Question about Linksys Wireless-G WRT54G Router

1 Answer

NOOK is not capable of responding to the Linksys router

I recenlty bought a nook. My wireless system is a Linksys wrt54GS. I was able to key in the WEP key into the NOOK and it did find and link to the router. HOwever, after a couple of minutes, the linksys disconnects. I called NOOK and the tech told me that the Linksys frequently sends out signals to identify the units linked to it and they respond. The NOOK I am told does not have the capability to respond. I was told that there is a MAC number listed in the NOOK settings which I have found and that I have to enter this MAC number into the LInksys router so that it will recognize the NOOK. How do I do this?

The tech was correct about that matter. However you can configure the MAC to always allow the device.

  1. Find your MAC for NOOK. I think you have already did.
  2. Go to Setting and then to the Second Page to find it.
  • Configuring MAC
  • Wireless MAC Filter. To filter wireless users by MAC Address, either permitting or blocking access, click Enable.
  • If you do not wish to filter users by MAC Address, select Disable.
  • Prevent. Clicking this button will block wireless access by MAC Address.
  • Permit Only. Clicking this button will allow wireless access by MAC Address.
  • Edit MAC Address Filter List. Clicking this button will open the MAC Address Filter List. On this screen, you can list users, by MAC Address, to whom you wish to provide or block access. For easy reference, click the Wireless
  • Client MAC List button to display a list of network users by MAC Address.
  • Change these settings as described here and click the Save Settings button to apply your changes or Cancel Changes to cancel your changes.

My Nook HD will not connect to the Netgear router. Is there something I can do?

It depends on the specific authentication or security method used by the router. A lot of newer devices will only use WPA/WPA2 security, a lot of older routers still use WEP security. If that is the case, you may need to log in to your router as administrator and change the security/authentication to WPA/WPA2 and choose a new password if the router supports that security protocol. If it does not you would have to buy a new router to connect the Nook to it.

Can't connect Nook internet wireless

further isolate the problem:

1. is the nook the only device that can connect wirelessly?
2. Make sure that the Password or the Network key is correct.
3. turn off/on the router and the nook
4. 'forget the network' on the wifi section on the nook
5. last recourse is to change the wireless settings (WEP) or do a firmware upgrade on the router.
-note that changing wireless settings will affect all your wifi devices. this means that you need to reconnect each one of them. if you have a lot, better think twice and just call tech support for further assistance

Can't connect my 2nd Nook Tablet

Since the nook is wireless, I don't understand what the problem is. Doesn't your nook make a wireless connection? Does it recognize any of the other wireless signals in your area? If it doesn't recognize any wireless signals, then the problem is in your nook and not from your router. Try going by a Barnes and Nobel book store and see if it will log onto theirs. And most Barnes and Nobles have people trained on Nook troubleshooting.

Access linksys wireless-g wrt54g with Nook tablet

Change the wireless network name and then change the key.
Try to connect to the new wireless network and see if that works.
If not then you can try to upgrade the firmware of your Linksys router.
After upgrading the firmware, reset the router and reconfigure it.

My nook wont connect to my linksys router. tech for nook said that linksys has a N connection and nook has a G connection. Can you fix the problem.

Go to your router setup page in Internet explorer.
If default leave user name blank and password is admin.
Click on Wireless and in the basic wireless setting there is a tab that says
wireless network mode. Set the mode to MIXED, save settings and try to connect.

Unable to get NOOK to work with Linksys WRT54GS

To log into your WRT54G, open a Web browser on a computer that's connected to your router and go to - the default username is admin and the default password is blank (leave the field empty).


In the Setup tab, Basic Setup subtab:

DHCP Server should be set to Enable.

If you had to change this setting, be sure to click the Save Settings button.


In the Wireless tab, Basic Wireless Settings subtab:

The first data item is Wireless Network Mode. For reasonable performance, this should be set to either Mixed or G-Only. You should be able to connect your NOOK even if it's set to B-Only, but that would be a very unusual setting and would give slower networking.

Wireless Network Name (SSID) is the name of your Wi-Fi network. If it still says 'linksys', change it to something different-but be aware that you'll need to reconnect all of your current Wi-Fi devices using the new SSID. That's a pain in the behind, but using the default SSID will cause you lots of connection grief if someone else installs a Wi-Fi router with the default SSID, because your devices won't be able to tell them apart. Write down your SSID, being careful to distinguish capital letters from small letters, so you'll know what it is.

Wireless SSID Broadcast should be set to Enable. Otherwise, your NOOK won't see your network. You could type in your SSID, but that's a pain in the behind that you don't need. There's no reason not to enable SSID broadcast.

If you had to make any changes to these settings, be sure to click the Save Settings button.


In the Wireless tab, Wireless Security subtab:

Security Mode: write down which of the choices is selected:
  • Disable
  • WPA Pre-Shared Key
  • WEP
I say to write this down just in case you run into more trouble and need to ask someone for help.

If 'Disable' is selected: you have no security on your Wi-Fi. Anyone can use your Internet connection, and anyone can listen in if they're in range. If you send unencrypted passwords, email, etc., they could see what you send. Most public Wi-Fi systems (McDonald's, Starbucks, B&N, etc.) have no security.

If either 'RADIUS' choice is selected: these settings are used for large organizations with stringent security requirements and a dedicated authentication server. Your NOOK cannot connect if either of these settings is used. You almost certainly don't want to be using either of these for a home system.

If the 'WPA Pre-Shared Key' choice is selected: WPA offers good security for Wi-Fi and is the best of these choices for home use.
  • WPA Algorithms should be set to TKIP. This is the normal setting for WPA. I don't know if your NOOK will connect if you set it to AES, which is normally used with WPA2 rather than WPA.
  • WPA Shared Key is the access key for your network. Write it down, being careful to distinguish capital letters and small letters. You'll definitely need this key in order to connect your NOOK or any other Wi-Fi device to your router. Don't change this unless you're prepared to go back and reconnect your other Wi-Fi devices. Unfortunately, there are some punctuation marks that you can't enter on the NOOK keyboard, and if your WPA passphrase contains one of those you may need to change the passphrase in order to connect your NOOK.
If 'WEP' is selected: the WEP security system is a weak system, easily cracked by knowledgeable hackers. However, many older wireless devices and some of the cheapest new wireless devices can't handle anything better than WEP. This isn't a good situation, but you work with what you've got.
  • Default Transmit Key should be set to 1.
  • Passphrase is not important. It is not your network's access key. Ignore it.
  • Key 1 is the access key for your network. Write it down. It will be either 10 or 26 characters, containing only the numbers 0-9 and the letters A-F. You will definitely need this key in order to connect your NOOK or any other Wi-Fi device to your router. There's no reason to change this, and if you do change it you'll have to go back and reconnect your other Wi-Fi devices.

If you had to make any changes to these settings, be sure to click the Save Settings button. Any changes in this section will also require that your existing Wi-Fi devices be reconnected.


In the Wireless tab, Wireless MAC Filter subtab:

  • Wireless MAC Filter should be set to Disable. If it's enabled and set to Permit only mode, only the devices listed on the MAC Filter List can use your Wi-Fi. If your NOOK isn't in the list, you can't connect your NOOK. Bad ju-ju, huh?
If you had to change this setting, be sure to click the Save Settings button. Changing this should not require your current Wi-Fi devices to reconnect.

It's possible to add your NOOK to the MAC Filtering list and then turn MAC Filtering back on. But that's beyond the scope of this posting. I will, however, mention that your NOOK's MAC address is listed in its Settings screen-on page 2 if it's a NOOK 3G.


In the Wireless tab, Advanced Wireless Settings subtab:

  • Authentication Type should be set to Auto. Do not set it to 'Shared Key'; this won't work with NOOK. Auto should work with any WEP-capable devices. If it's set to 'Shared Key', change it to 'Auto'-this shouldn't affect any of your current Wi-Fi devices.
If you had to change this setting, be sure to click the Save Settings button. Changing this should not require your current Wi-Fi devices to reconnect.


You should now be able to connect your NOOK using the SSID and the access key that you wrote down.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response. Happy Holidays!

Thanks, Joe

My nook won't connect to my linksys cisco rooter.

Check your settings. You may need to make sure the SSID is being broadcast and make sure the router is set to allow connections.
You may also be able to add the nook's MAC address so the router will see it.
