Akwana was shown the door on Wednesday after only four months in charge of the trouble ridden team that is second from bottom on the log after nine matches.
“We arrived at the decision to part ways with him due to continued poor results and gross misconduct,” said Rangers chairman Yobesh Ongeri.
Akwana was fired from Sofapaka last season under similar claims of indiscipline before taking charge at Huruma Youth where he was contracted by Rangers at the beginning of the season.
The club has only won one KPL game under his charge and lost out to Tusker FC 3-2 to bow out of the Top 8 tournament.
His reign will be remembered for his side soaking in 12 goals in successive league games the latest a 6-2 shellacking at the hands of AFC Leopards in Mumias that was preceded by a 6-0 beating by Thika United.
During his tenure, player unrest over non-payment rocked the side leading to the captain, Pascal Ochieng announcing he had quit Rangers last week.
The team lone KPL win their 2-1 success over Western Stima last month while drawing against Gor Mahia, City Stars as well as new boys Oserian and Muhoroni Youth.
His replacement is a former player at Tusker FC and his first game in charge will be against Karuturi Sport this weekend at City Stadium.
