bash expect stops after ***

I have a very simple expect script to connect to a Cisco Wireless Lan Controller via Cisco router. My problem is that after some commands expect stops suddenly without finish all sentences and without any error. I think that the problem is with * from password but I'm not sure. That's my script

#!/usr/bin/expect
set timeout 10

spawn telnet X.Y.Z.W

expect "User Access Verification"
expect "Username:"
send "admin\r"
expect "Password:"
send "PASSWORD\r"
expect "Router#"
send "telnet WLC_IP\r"
expect "(Cisco Controller)"
expect "User:"
send "admin\r"
expect "Password:"
send "PASSWORD\r"
expect "Cisco Controller"
send " config paging disable\r"
expect "Cisco Controller"
send " show ap auto-rf 802.11b AP-NAME\r"
expect "Cisco Controller"
send "logout\r";

And this is the output after running,

spawn telnet X.Y.Z.W
Trying X.Y.Z.W...
Connected to X.Y.Z.W.
Escape character is '^]'.


User Access Verification

Username: admin
Password:

Router#telnet WLC_IP
Trying WLC_IP ... Open

Also, there are an "?" after password that I don't know why is it.

Any ideas?

Thanks in advance!

after setting expect eof at the end of my script it works well! I'm not sure if it's mandatory but works for me.

Thank you!
