NETGEAR N300 (Model No. D1500) telnet help

*I've made text in bold and Italic those copy paste information to make the thread easier to read

Hello, I've bought this router not long ago and I was looking forward to telnet but I am starting to doubt whether it is possible or I am doing something wrong :

Tested telnetEnable.exe on Windows and the compiled version on ubuntu, basically this is where I'm stuck (the beginning)

root@ubuntu:~/telnet# telnet
Connected to
Escape character is '^]'.
Connection closed by foreign host.

Now, I will try to give you guys who are for sure more expert than me all the info you need to help me if possible, please.

root@ubuntu:~/telnet# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface         UG    0      0        0 eth0   U     1      0        0 eth0

route -n and arping to see MAC and default gateway

root@ubuntu:~/telnet# arping -I eth0
ARPING from eth0
Unicast reply from [XXXXXXXXXXXX]  3.359ms
Unicast reply from [XXXXXXXXXXXX]  0.850ms
^CSent 2 probes (1 broadcast(s))
Received 2 response(s)

Now, nmap shows port 23 is open but tcpwrapped so i assume it still should work?

root@ubuntu:~/telnet# nmap -A -T4

Starting Nmap 6.40 ( ) at 2014-09-07 20:07 UTC

Now, I've tried to do everything I could but without success. I must either be doing something wrong or it is not possible with this router to access telnet (would like to boost snr).

I think this is all the possible informatio nive gathered so far, let me know what else to try.


THANK YOU in advance.
