The optical cable is brought to my apartment, connected to D-Link DMC-920. Cisco EA6300 router is connected to it with the last firmware. My PC and the TV set (SmartTV) are connected by a cable, a notebook and 3 cellular on Wi-Fi.
Problem:
The WAN port sometimes loses the IP settings from provider - is dropped on 0.0.0.0. Improves reset of a router or via the WEB interface reset of the WAN parameters.
Quality of translation of TV worsened: artifacts, the picture, stop frames, friezes pours and or the channel doesn't turn on at all.
I used Dlink DIR-615 instead of EA6300 earlier - everything was ideal.
I tried to change a traffic priority at TV - doesn't help.
I put back Dir-615 and all problems disappear.
Really I in vain spent 190USD (the price in my region) for this trash?
