I just bought a brand new Speedport W 723V, and I can't read German! I'm pretty sure that I've set it up right, I just can't connect to the configuration site. Please help!
I'll try to assist :-)
Have you already run the autoconfiguration?? http://autokonfig.telekom.de
It should ask you to enter the DSL telephone number and the "Personlich Kennwort". This info should have come in the mail separately from the router.
After the settings are put in you should have Internet access.
At any time you can manually review and modify all the settings for the router by getting into the configuration.
The configuration page is reached by opening a browser and entering either https://speedport.ip
on the address line.
The password is located on a label on the backside of the router.
Hope this helps!
If you get stuck or need more help, feel free to send me a PM.
