Arduino Yun not showing Arduino-xxxxxxx but Linino-xxxxxxx

Dear all,

I was currently cheecking my newly bought Arduino Yun. Which initially showed Arduino-xxxxxxx on my laptop WiFi. But after some jobs I did unknowingly it got changed into Linino-xxxxxxx on my laptop's WiFi.

I am worried what has happened?

Kindly help me to make it show Arduino-xxxxxxx again on WiFi.

Please help.
