Utstarcom 300 R2u Modem/router Hanged Twice In Two Weeks

UTStarcom's 300 R2U modem/router here has hanged twice in two weeks since it was delivered. The first time its status light turned off while all other lights remained on. The second time its status light stayed on. Normally it should be blinking. Each time I had to reboot it manually since accessing it via browser/telnet was impossible. Have any of the users of this modem/router faced similar issues?

no such problems here, mine has been running continuously for past 12 days
