Cisco – How Connect to Cisco router for the First Time

ciscoconfigurationconnectionrouter

I recently purchased a new Cisco 881W and I am trying to connect to setup the initial configuration. The last time I did this about three years ago I connected over a serial link to the console port, but I no longer have a computer with a legacy serial port available and I really can't wait for a serial to USB converter to come in the mail.

So, I tried to connect using Cisco CP Express. I got as far as the CP Express splash screen popup with a message that says "Loading Cisco CP Express… Please wait." But then another poup appears that says

Cisco CP Express Application could not be launched. If CP Express is
lanuched using https try the following steps and relanuch CP Express.
1. Disable TLS option in JRE Settings. Please close all Cisco CP Express windows before proceeding.

Needless to say, I've tried diabling TLS… and I wasn't using https anyway. Is it possible to debug connecting to CP Express?

From Cisco's docwiki page for troubleshooting CP Express:

JRE settings for Cisco CP

The following JRE settings are needed for Cisco CP to function properly:

Go to Start > Control Panel > Java.
Click View under Java Applet Runtime Settings.
Select your JRE in use.
Set the "Java runtime parameters" with the value "-Xmx256m -Dsun.java2d.d3d=false".

In addition, if JRE is upgraded to versions 1.6.0_11 or above, the following settings are needed after installing Cisco CP:

Go to Start > Control Panel > Java > Advance.
Select "Java Plug-in" tree.
Uncheck the check box for Enable next-generation Java Plug-in.
Restart Cisco CP.
