Hello there, 
i just brought this router from my local store few weeks ago. At first it was Ok but day by day its causign may problems.

Problem 1. Sometimes when i reboot my router (because it slows down) it doesnt connects to the internet and shows red light. I tried manually connect , here are my settings right now Connection mode : always On 

Auth type : Auto auth

connection type : PPPoE 

i unplug the cable and tried to connect with my laptop to see if the internet is ok or not , and my internet was ok. 
When i trun off router for few mins then turn on it connects sometimes
i tried Enable SPI Firewall and also disable firewall too. same problem everytime. 

Problem 2 : I have 2 modes turned on 5ghz and 2.4 ghz i tried to limit speed to some devices using bandwith control so i reserved 3 Ip 192.168.0.100-103 to my main devices via DHCP adress reservation. but after sometime my 3 devices slows down so i stopped usign that feature. 


i Had to reboot every 6 hours to keep my device speed going. is there a fix or anything i can do. please help me out here guys.
