(How do I change the passphrase on my SBG6580)

Wi-Fi is rapidly replacing wired LAN in homes and offices. This is the reason most high-end printers now come with Wi-Fi built into them. Now you can print documents wirelessly without attaching cables. However, before you print, you need to connect and configure your printer to print over a Wi-Fi connection. In order for the wifi to work, your printer and your computer must connect to the same wifi router or to an access point/repeater/extender connected to the same router.
1. Open Internet Explorer, on the address bar type 192.168.1.1
2. There's no username and type admin on the password. If admin didn't work, use your own password.
3. When you have the Setup Page open, click on Wireless Tab, then click on the sub-tab Wireless Security.
4. There you can see the Security Mode. If the mode is set to WEP, the WEP Key 1 is your wireless key. If the mode is set to the WPA-Personal, the Passphrase or the WPA Shared Key is your wireless key/PIN.try this steps and fix problems let if you have facing this problems call canon printer technical support Experts toll-free number 1-800-213-8289 for get online help.

I shall have to assume you in a 'Factory Reset' situation, where you have not signed into the modem, and changed username/password defaults, (new unit, fresh out of the box).
Do not connect to the cable company yet. First, secure the modem.....
From the User Manual, page 9..... You do have a User Manual?
1. Open a browser window, after connecting your computer.

Use a 'wired' connection. Never change security settings, using Wi-Fi connection.....

2. Type in the IP address for the modem 192.168.0.1 in the URL address. That should take you to the modem's password change window.
3. Type in the default Username: admin.
4. Type in the default Password: motorola.
5. Type in your new username in the Password Change Username field.
6. Type in your new password in the New Password field.
7. Re-enter your new password
8. Re-type your new username in the Current Username Password field.
9. Click Apply.
10. Connect the modem to the cable company. You should shortly be able to go online, after the modem has synchronized to the cable company. That usually takes about a minute.

Your question asks for the 'security key'. That generally refers to the Wi-Fi settings. If that is the case, go to the 192.168.0.1 address, sign-in, and click on Wireless. Follow the obvious directions.... Or, post here again....

if you have access to the wi-fi router, you can reset it to default password by pressing reset button on the router, this will revert it back to the factory settings, including router name and password, the password will be on the router itself.

Network security key
Some later model wireless routers have the Password (ie.Encryption key) and the SSID already configured in the wireless router and this information is printed on a label on the bottom of the router.
These settings can be used to configure the wireless card and wireless adapters in your computer/laptop.
If these settings do not suit you, then it can be changed to suit your requirements.
The encryption key secures your data and wireless connection from unauthorized access.To configure the wireless settings in the router, connect a LAN cable from your computer to the wireless router, then open a Browser on your computer and enter the router's configuration IP address, then enter the admin login and password and then go to the wireless settings and configure the SSID and Encryption key.
The router's encryption key can be a Passphrase or the WEP or WPA or WPA2 key.If you use the Passphrase method select either WEP or WPA or WPA2 to generate the encryption key. You can enter the WEP or WPA or WPA2 key with 8 to 63 ASCII characters or 64 Hex digits.
Most people use Passphrase which is easier to remember eg. I was born in January 1988.
The strongest and latest security is WPA2, the weakest and oldest is WEP. To connect to your wireless router from the computer/laptop, configure the wireless card in your computer/laptop with the router's wireless settings ie SSID, plus the WPA or WPA2 encryption key. Then computer/laptops can communicate with your wireless router. http://www.fixya.com/support/r10267861-network_security_key

last man running XP the virus magnet , oops???? no future there.
no PC told no wifi card model told. and what 2wire means I guess 2 antenna wires sure.
SBG6580 this is cable mode + router both in one, AIO +wifi 'N" grade step 1; the PC works great i wired mode ethernet to rear of surfboard
no, then the modem is failing call the ISP.
yes, wired works
so now comes pesky love/hate wifi next.
1billion posts on the web, pain. ... I can fix them all but is hard work.

rule one in this regard, NO PC told but
WPA (1) must be enaBled the router side. of surfboard.
I have all mine set to wpa2/3. (wep and wpa1 blocked)
as did yours new, wpa1 is off.
but you do as you want if old things in the home that only do wpa1.
then what you set.
the SSID and PW are both , case sensitive.
worse yet some characters are not allowed either end.
page 24 in your manual states, RTM amazing what is there, behold.

WPA2-PSK is automatically set as the default

page 47 shows, and do pick it there inside the router
this
Select one of the following wireless network security options for your wireless network from the
Wireless Security drop-down list:
WPA: Wi-Fi Protected Access
WPA-PSK: Wi-Fi Protected Access with Pre-Shared Key, standard encryption
WPA2: Wi-Fi Protected Access version 2 with Pre-Shared Key, standard encryption with the AES
encryption type
WPA2-PSK: Wi-Fi Protected Access version 2 with Pre-Shared Key (recommended)
8.Choose the wireless network encryption type in the Encryption field:
AES- Advanced Encryption Standard: Provides the strongest encryption (recommended)
AES+TKIP- Advanced Encryption Standard and Temporal Key Integrity Protocol: Allows both
AES and TKIP-capable clients to connect to your wireless network.
just so you know, newer routers are like this,.today...
and are way more secure too and less bugs. ! old bad, new good.

ad_hoc or guess mode are gone forever
WPS+ pin gone ,too, (now, new Netgear is preset ssd +pass ,NIB
label on router shows this.fact. and WPS button GONE.

WEP gone for ever, it is insecure max.
wpa (fear growing) but may have it or just alone.aka wpa1.
or show up as wpa1/2
then see WPA2/3, like mine, and wpa1 is single choice.
what your PC and TV;s need and demand I can not guess.


is using a PC learn what WPA it uses.(age of PC is the key)
learn what other things in home use or need (IOT)
yes some old things are wpa 1 only. no higher.
then make your choices for sure all same and wpa2 if can.
and then set the router to that.
and use a PW that is only alpha- numeric and does not use dictionary words. or all upper or lower, mixed can be hard to learn
here is me using lastpass, autogen
example: only, use a one case SSID.

The encryption key secures your data from unauthorized access.
The router's password is a Passphrase or the WEP or WPA orWPA2 encryption key. The Passphrase generates the WEP or WPA or WPA2 encryptionkey and this is in the router's wireless settings. To connect to your wireless router, it needs the router'swireless settings configured ie SSID, WPA or WPA2 encryption key and also thewireless cards in all the laptops and or computers needs to be configured withthese router's wireless settings. Then the laptops and desktop computers cancommunicate with your wireless router.

To log into your WRT54G, open a Web browser on a computer that's connected to your router and go to http://192.168.1.1/ - 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
• WPA RADIUS
• RADIUS
• 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.

Hi,
Solution Overview
This article explains how you can avoid having to run the Wireless Configuration Utility or Wireless Setup Assistant (Macintosh) after making changes to the router's security settings. The need to change these settings can arise if users forget their network key/passphrase or router web server password or if you have security concerns.
Printer response to security settings changes
The printer will respond with a flashing orange () Wi-Fi indicator light after the following actions are performed on the network or router/access point (AP):

• -A change to the Service Set Identifier (SSID) or network name.


• -A change to the security type (none, WEP, WPA, or WPA2 personal).


• -A change to the security network key/passphrase.


• -A hard reset of the router followed by entry of security values that are different from the original values.


• -The printer is moved to a network (AP) that has different security values but already has installed drivers and created ports. NOTE: Port reconfiguration may be required in this case. Click here for instructions.

In order to rejoin (associate and authenticate) the wireless network (WLAN), the wireless client (printer) has to be reconfigured with the router's new SSID, security type, and network key. This requires connecting the USB configuration cable to the host computer and running the Wireless Configuration Utility or Wireless Setup Assistant to apply the new security settings on the printer's wireless network adapter.
Solution: Change the printer settings first
Change the security settings on the printer while it is still communicating on the network before making the changes on the router. Understand that this will cause a temporary change in the Wi-Fi indicator light from to . After you have made equivalent changes on the router, the printer's Wi-Fi indicator light will return to .
Procedure: How to change security settings via the embedded web server
If you change your AP security settings frequently, this procedure is for you.

1. Open your web browser application and enter the printer IP address into the web address field, i.e. http://ip_address.


2. Click on Configuration.


3. Click on Wireless.


4. Enter the SSID, security type/encryption, and network key that will be used to configure the router.


5. Click Submit.
   

First connect your router to computer with ethernet cable.
Then you can access it with following link
http://192.168.1.1
or
http://192.168.0.1
type user as "admin" and password as "admin" or blank or "password"
then go to wi fi security set your WEP code it is your security key to connect wi fi network.
Change it and then save settings and restart router.
Let me know if you need more assistance.
Thanks

Ok... There are tree things you need to know about securing your WI-FI network.

1: Each computer needs to have "permision" to access your WI-FI network.


2: The "Passphrase" and the "Key" are not the same thing. The "Passphrase" doesn't always work. But the "Key" should. (MACs will need the "key")


3: Some WI-FI equipment is "too old" to use 128 bit WEP or WPA.
(I don't think this aplies to your problem)
