I'll assume the password XXXXX have forgotten was the password XXXXX access the linksys device via the website at http://192.168.1.1
You can leave the username blank and try admin as the password. That is the default, you can see if that works first.
If it does not work you can reset the device back to factory default by following the below instructions:
With your router connected to power and turned on, press and hold the Reset button on the bottom of your router for 5-10 seconds
This will erase all of the previous configuration and you will need to reset up your router as you did when it was first purchased.
If the password XXXXX have forgotten is just the one used to connect different devices to your wireless network then try the below
access the linksys device via the website at http://192.168.1.1
You can leave the username blank and try admin as the password. That is the default, you can see if that works. once your in the router's configuration pages click on the "wireless" tab at the top and then security, it should show you the connection password.
ok, we can change it to something easier and then you just need to reconnect any devices already setup with the new password. Follow the below to make the changes :
login to the router via this link http://192.168.1.1 username is XXXXX XXXXX XXXXX XXXXX
click on the wireless tab then click on "basic wireless settings" now click "manual" and click save settings
now click on wireless again and then wireless security
in this window change the security mode drop down to WPA2
enter a passphrase. this will be your password XXXXX connect to the wireless network. So you can make this something easy. i believe there is a number of characters that need to be used. make it a word at least 8 characters long.
now click save settings.
that should do it. now go to a wireless device and try to connect to your network. it should have the same name as before but a different password (the one you just set it as)
let me know if everything is working now.
Sorry, we can only communicate via this message post. Let's take a step back, the way your internet should be setup is you have a modem from your internet provider, that should be connected to the linksys router and then your pc should be connected via a network cable to your computer. (sometimes you wont have a modem from your internet provider and the connection goes right to the linksys router)
Once you are connected like that you should have access to the internet then you can connect to the linksys device by going to http://192.168.1.1 and follow the above instructions.
