Problem:
- Ping to gateway (Mikrotik NAS) is 1 or <1ms when client is connected and idle(no bandwidth utilization).
- As soon as client starts browsing latency increases to 200 -500 ms.
- As client starts downloading files, latency goes >2000 ms sometimes and eventually results in RTO to gateway.
NAS is directly connected to client via switch.
Here are the screen shots
Mikrotik Config:
In short it’s a simple setup with a hotspot interface and an wan interface.
