Model purchased around 5 months ago. All worked fine until now.
Now I notice that after certain intervals of time after I connect to wifi network the router cuts down speed, sometimes pages just got stuck. I notice a torrent download goes down from 5Mb/s to around and below 300Kb/s. It does not reconnect automatically though. Once I manually click Disconnect button and then Connect - it works at normal speed immediately and for some time period until it is stuck at low speed again.
I tested this using cable connection. Cable shows stable speed.
Can this be fixed at home or needs service center to check the device?
