Hi, I'm currently using the free router which came with the Unifi 100Mbps package which is the TP-Link AC1200. However, it seems that either due to bad firmware or generally just my routers problem I'm having alot of problems like bad wifi connection or overload (can't cnnect) and router's cpu constantly at 100%.

I would like to know if theres any recommendation for other routers which support dual band and gigabit connection. Have a budget of RM 350-450.

Thank you very much
