You may need to reset your device and you will see a reset button at back of your router so all you need is to keep holding it for 10 seconds then unplug the power jack for like 1 min and then your device shall be reset.But please make sure to backup your all settings first.
Good Luck

The User Name field should be left blank and the password is admin.

hi yvo2000. Sorry, you cant do that. That router (well, the SPA2102) needs a cable from your neighbor's router in order to provide internet to the POTS jacks. Please don't forget to rate my answer if it helped you. Thank you :D

If it's locked to sunrocket, google for SPA2102 sunrocket unlock. Loads of how-tos out there.
If it's not sunrocket, go to broadbandreports.com and send a PM to DogFace05. He has a small business based around unlocking SPA2102 routers (so it's not free - but will turn your SPA into something usable)

your SPA2102-R seems to have one ethernet connection and one internet connection.
your WRT54G-TM seems to have one internet connection and 4 ethernet connections.

What you are trying to achive is; plug a ethernet cable into the ethernet connection on your SPA2102-R then plug the other end into the internet port of the WRT54G-TM

hope this helps, I have assumed that you intend to use a DSL broadband supplier not ADSL.

if you are changing service from DSL to ADSL then your WRT54G-TM needs to be first in line configured and working. then plug the internet port from the SPA2102-R into any of the WRT54G-TM ethernet ports.

I have the same problem and I configure my router in PPPoe with my username and password provided by my ISP and now my router is working...

you are able to access the IVR, reset it back to factory default settings. Dial 73738# and press 1 to confirm the reset.

try this out
power on your linksys
then pick up the phone connected to that linksys
no dile tone required
dial ****
when it says configuration menu
type 73738#
if ask for password then nothing can help you buddy
and if it says press 1 to save then press 1 and your device is reset with factory default

The Linksys comes with web admin access disabled.

To enable it, pick up phone, dial **** then 723646# , when asked for password, dial 78778839# , when asked for value dial 1# then dial 1 to save.

Then, go to »192.168.0.1/admin/voice/advanced , enter user and password.

If you did a factory reset, you will need to call Linksys technical support.
