A strange IP address in my network!!

Well I might make the following shade of grey suggestion. IANAL but I'd argue the following.

192.168.x.x falls within RFC1918 therefore you should have no exectation of it being a remote system (you should fully expect it to be local) therefore knowing that it has telnet running there's no reason you shouldn't attempt to telnet to the device/system. If once you telnet you receive a banner saying "authorized people only...." kind thing then obviously disconnect but the telnet banner might give you some useful info as to who/what the device/system is.

But what if you think this device maybe the embedded telnet application in some of your machines? Thats why you do trace route.

Chances are, your ISP is doing some funky NAT work using the 192.168.x.x network

I agree too

If I thought it was one of my machines (which is a reasonable assumption based on RFC1918 address space), I'd simply go ahead and connect. No need to traceroute.

Considering the ports, Ip and data received that most probably is Wifi acces point.
And about port scanning in finland that is a criminal offense equal to tresspassing.
running actual exploits would be = to breaking an entry.
