Only you know your SSID( username)and Security Key(password). You can RESET the device to default settings by pushing and holding the reset button for 30 seconds or so and release. That will reset to default setting. Then you can reconfigure the SSID and Security Key, You may want to write down the info for future use. This may help: http://www.zhone.com/products/1518-A1/

modems don't have any settings unless you are referring to a modem/router combo. Routers or modem/router combos, commercial/home grade routers can be reset by locating the reset button, or pin sided hole on the back of the router typically labeled "reset" press and hold for 10+ seconds and this will restore the device to factory settings including passwords.

Reset your router back to it's factory settings by holding the reset button for about 5 seconds. I have provided a list of the most popular router brands. If it does not work you may need to google what your specific model's default IP address/default username/default passwords are, for example search for "Encore ENHWI-2AN3 default IP address" The default login info can change, it can depend on where you obtained your router. If you purchased it yourself from a store then the standard defaults should work. If you obtained your router from your Internet Provider you may need to contact your service provider. It also may depend whether it's an old or new model router as well. And you may need to press and hold the reset button on your router several times before it actually clears. Make sure you have a wired connection then once you have accessed your router simply run the Setup Wizard. Set your SSID as something you'll remember like "Mavericks Network" and your Password can be something like your phone number for example 3109876543

if you are in IL and on consolidated communications, which just loves these boxes.. try admin/cciadmin

For that Connect your router to computer with ethernet cable then you can access it with following default link.
http://192.168.0.1
or
http://192.168.1.1
If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it.
Then it ask for user name and password.
Type user as "admin" and password as "admin" or "password" or blank.
Then you can see configuration page of router.
Then click on WAN settings and change MTU settings then save settings and restart router.
Let me know if you need further assistance.
Thanks for using FixYa.

you will need to use the power supply that came with the zhone
router......other power supplies are not interchangeable.

make sure all other items that are pluged into the other phone jacks
have inline dsl filters....do not filter the router...if you have the whole
house filter on the outside of your house you will not need to put inline
filters inside ...

make sure there are no loose connections...

last call you isp provider

You need to hold the reset the device. Most hardware get back to factory defaults once they are reset . That should help
Thanks
