ASIC miner not staying on my network

Hello there I have an bitmain antminer T9+ and it will not stay up on my network for more than 20 minutes. When it gets fully booted up the miner details page has all the proper information on it, but after 20 minutes of mining or so it drops off and the mining details page is blank and all stats stop updating. I have it connected trough a powerline adapter and it is DHCP, do I need to make it an static IP? I have also gone into my router and allocated the IP for the miner. Can anyone give me any ideas or suggestions on how to fix this problem so I can turn my miner on and continue mining throughout the day.

Is there any red led light also try these.

  1. Reset it
  2. reinstall firmware.if resetting does not work.
