What I need?

• router with gigabit ports
• VLAN support
• WiFi 2.4/5GHz
• IGMP Snooping (nice to have)
• easy firmware update (without any issue such like reset to default settings after update)
• most important there shouldn't be any multicast packet drop (i.e. no pixels squares) during testing procedure

Testing configuration looks like

• internet tariff:  300 Mb/s download and 150 Mb/s upload
• two laptops in LAN ports 1 and 2
• one STB MAG 255 in LAN port 3 with full HD stream
• one IPTV multicast probe STB-1001S2 with IPERF in LAN port 4

What did the test procedure look like?

• download multiple torrents to saturate of tariff limits
• flooooofig with hping3 --flood IP
• parallel download 10GB files to two laptops

Which router did I tested?

• Uplink WR1200AC => FAIL
• Totolink A3002RU => FAIL
• RB951G-2HnD => FAIL
• D-Link DIR-842 C3 => FAIL
• D-Link DIR-825/EE rev G1 => PASS
• TP-Link Archer C6 v2.0 => FAIL
• TP-Link Archer C5 v4.0 (no VLAN support) => FAIL

All failed routers generates STBPlayer: TS Continuity Counter error on multicast probe.

Only one D-Link DIR-825/EE pass all test.

What problem registred multicast probe?

• Out of order 1
• Our of order 2
• Packet loss 1
• Packet loss 2
