ZTE 801a Ethernet keeps dropping

[Dazzar]

I have the ZTE801a and the Ethernet ports just stop working, I switch it around they work again then stop I switch them back and they work again and it repeats it again and again  anyone else had this problem or does the router need flying lessons !

I have same router  but do not as router  only using modem  so all wifi disabled just one port using  for  wan 

Look like working  ok  Just  three  limiting speed  this  is bad  "traffic management "

The router when I tested  via wifi  feels little week  I mean  for my  need this  wifi to week  will be overloaded from my equipment

• My router firmware  / software  last digits  B12 
• Try to reset  router  you can do this  advance settings > other > reset
• I have try couple things on router and  it  did not like changes  and  my wan port was  put on router side and no matter what I done  the settings gone inside parameters  and to fix this was reset  then  I know  now do not touch  as  router is locked  and there is minimal what can be done
