How do I change the Admin password on a Norstar from the default?

Using the default password, "Passwords" is the fourth menu entry, and under that, "Programming passwords" is the fourth also. Under that there is "Installer", "Sys Admin", and "Basic" (depending on your KSU model and software version).

Forgot my password.

If you ever forget your password to your router you can look up the default password online.
Most default passwords for linksys is: login=blank password=admin
Default passwords for belkin is: blank
Default passwords for netgear: login=admin password=password
Default passwords for d-link: login=admin password=1234 or password.

if none of the passwords work then you can reset the router to factory defaults by holding the reset button in with a paperclip for 30 seconds while powered on. This will erase any customized settings and apply the factory default settings. If the password doesn't work please check with your device manual.

How to Reset BIOS Password?

There are two passwords in BIOS. One is start up password, the other isBIOS setting password. If you have forgotten the start up password thatmeans you cannot open computer at all. Then the first method is theonly thing you can do. Other methods can use to clear setting password.
==①:Motherboard Battery Discharge==
The common way toreset start up password is discharge Motherboard Battery. Most of thecurrent motherboard BIOS is using the button batteries to provideelectric power.That means if there is no electricity, the informationit contains will be lost. When it’s on power again, BIOS will set backto its original state, of course, there will be no BIOS passwords. Butyou will lose your setting at the same time.
What we need to dois to power off computer, open the computer box, and then unplug thepower plug of the computer to make sure that it is no electricity atall. Then locate the white silver button battery on the motherboard.Remove the battery carefully. Perhaps 30 seconds later, put back thebattery.
After put back the computer box then power on, thesystem will prompt “CMOS Checksum Error-Defaults Loaded”. That meansCMOS errors detected during inspections, had been included in thesystem default, BIOS password cracking success!
On somemotherboards, the battery is soldered to the motherboard, making itdifficult to remove. If this is the case, you have another alternative.Somewhere on the motherboard you should find a jumper that will clearthe BIOS password. If you have the motherboard documentation, you willknow where that jumper is. If not, the jumper may be labeled on themotherboard. If you are not fortunate enough for either of these to bethe case, you may be able to guess which jumper is the correct jumper.This jumper is usually standing alone near the battery. If you cannotlocate this jumper, you might short both of the points where thebattery connects to the motherboard.
==② : Backdoor BIOS Password==
Eachmotherboard manufacturer has set a backdoor password in order tofacilitate the provision of technical support. The backdoor password isa BIOS password that works, no matter what the user sets the BIOSpassword to. These passwords are typically used for testing andmaintenance. Manufacturers typically change the backdoor BIOS passwordsfrom time to time.
AMI Backdoor BIOS Passwords
Award Backdoor BIOS Passwords
Onereported Award backdoor BIOS password is eight spaces. Other reportedAward backdoor BIOS passwords include 01322222, 589589, 589721, 595595,598598 , ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD PW, AWARDSW, AWARD?SW, AWARD_PW, AWARD_SW, AWKWARD, awkward, BIOSTAR, CONCAT,CONDO, Condo, condo, d8on, djonet, HLT, J256, J262, j262, j322, j332,J64, KDD, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOX, SYXZ, syxz,TTPTHA, ZAAAADA, ZAAADA, ZBAAACA, and ZJAAADC.
Phoenix Backdoor BIOS Passwords
ReportedPhoenix BIOS backdoor passwords include BIOS, CMOS, phoenix, andPHOENIX. Backdoor BIOS Passwords from Other Manufacturers Reported BIOSbackdoor passwords for other manufacturers include:
ManufacturerBIOS Password
VOBIS&IBM merlin
Dell Dell
Biostar Biostar
Compaq Compaq
Epox central
Freetech PosterieI
Will iwill
Jetway spooml
Packard Bell bell9
Siemens SKY_FOX
Remember that what you see listed may not be the actual backdoor BIOS password,this BIOS password may simply have the same checksum as the realbackdoor BIOS password. For Award BIOS, this checksum is stored atF000:EC60.
==③: Software Crack==
There are a lotsoftwares to test systems or start up password, but they need to run onWindows. So it is only used to reset BIOS setting password.
!BIOS will recover the BIOS password for most common BIOS versions, including IBM, American Megatrends Inc, Award and Phoenix.
CmosPwd will recover the BIOS password for the following BIOS versions:
•AMI WinBIOS 2.5
•Award 4.5x/4.6x/6.0
•Compaq (1992)
•Compaq (New version)
•IBM (PS/2, Activa, Thinkpad)
•Packard Bell
•Phoenix 1.00.09.AC0 (1994), a486 1.03, 1.04, 1.10 A03, 4.05 rev 1.02.943, 4.06 rev 1.13.1107
•Phoenix 4 release 6 (User)
•Gateway Solo - Phoenix 4.0 release 6
•Zenith AMI
Ifall else fails, you might be going to lose some money for technician.But they will use these same methods, try hard by yourself.

Dell inspiron mini 10 bios password

Step 1:
BIOS is the first function run by a computer when turned on. It is known as "Boot Firmware," and it checks and initializes other components in your computer, such as your video chip, hard disk or sound card. Because this is the initial process in a computer, it can be troublesome for users who forget their BIOS password and need to access the BIOS. There are several main strategies to attempt when trying to bypass a BIOS password, including accessing the hard disk (which should contain the BIOS password), trying backdoor BIOS passwords (backdoor passwords are generic passwords created by manufacturers in case the user password is lost or forgotten), and flashing the BIOS (flashing is the process of overwriting the original data with new data).

Enter the CMOS start-up menu when you turn on the machine by pressing DEL, F2, or CTRL + ALT + DEL during the boot sequence. Go to STANDARD CMOS SETUP. Find control options for the hard disk. Change both TYPE and MODE to: AUTO. Reboot the system. You will now have access to the hard disk. From this menu, you should be able to find basic system passwords, including the BIOS password. b> Trying Standard Backdoor Passwords For AWARD BIOS, try the following passwords: "AWARD SW, AWARD_SW, Award SW, AWARD PW, _award, awkward, J64, j256, j262, j332, j322, 01322222, 589589, 589721, 595595, 598598, HLT, SER, SKY_FOX, aLLy, aLLY, Condo, CONCAT, TTPTHA, aPAf, HLT, KDD, ZBAAACA, ZAAADA, ZJAAADC, djonet." For AMI BIOS, try the following passwords: "AMI, A.M.I., AMI SW, AMI_SW, BIOS, PASSWORD, HEWITT RAND, Oder." For all other types of BIOSes, try the following passwords: "LKWPETER, lkwpeter, BIOSTAR, biostar, BIOSSTAR, biosstar, ALFAROME, Syxz, Wodj." b> Flashing the BIOS in Software Access MS DOS and type "DEBUG" at the command prompt. This will bring up the DEBUG menu. Type the following code for AMI/AWARD BIOS (note: the Os are the letter "oh," not the numeral "Zero"):
"O 70 17
O 71 17
Q" Type the following code for Phoenix BIOS (note: the Os are the letter "oh," not the numeral "Zero"):
"O 70 FF
O 71 17
Q" If the previous steps yield no results, try the following code:
"O 70 2E
O 71 FF

Need to find my passwords when i set up router

You can Restore Factory Settings by putting something sharp like a paper clip into the small reset hole in the back. This will default the router's username to 'admin' and the password to 'password', and the encryption password will be disabled, so you can connect your phone to the internet.
You can access the router's menu via
Then go to Firewall or Security (just look through the menu) and enable WEP or WPA and set new passwords and write them down somewhere safe!
Hope this helps
