Hi All,
this is my first topic.
I have one routerboard CCR1009 in my home (version with passive dissipation, no noise otherwise my wife throws me out of the house ( .... ).
Configured in load balance and failover through wiki mikrotik (3 WAN) and 1 LAN in OUT.
The LAN OUT is connected a switch Netgear GS116, but all client connected (laptop and pc) in this switch lost packets (loss over 40% of the packets).
Are novice and not understand this problem .... loop? collision?

So you have created a bridge over two ports? Where does to packet loss occur, between the router and the clients?

Post your configuration "/export compact"

Start by looking at the cable between the CCR and netgear device, replace if necessary

Thanks for reply Mada3k and Czfan,
answer your question.
CZFAN: I tried with another cable Cat.5E, but nothing....

MADA3K: None bridge ports in my configuration
Loss packet starts when attach CCR on switch with clients.
I have try another switch "Hp procurve 16 ports" always gigabit, equal problem.

Example: I have start ping 8.8.8.8 in terminal of CCR, ping started normally, zero loss packet. Just attached port WAN OUT at switch, started loss packet in terminal CCR and the clients equal

You cannot use 193.168.0.0/20 on your LAN as it is a public routed subnet not a Private allocated one!

Hi IngDaka,
thanks for reply.
Sorry I'm not very experienced in the matter.
What addressing can I use for my LAN? (in total 11 terminals between pc, laptop, nas and other)

You can use 172.16.0.0/24 range is allocated for private!

Convert all my LAN address on mask 172.16.0.0/24 and set address interface WAN-OUT 172.16.0.1, but continue to lost packet or collision
