Hello. I cant make my MikroTik RB951G-2HnD (ROS 6.4, f/w 3.08) work with network AV receiver Yamaha HTR-6064 / RX-V671(f/w 1.47). Both pieces of hardware work well by their own but not together. If I set receiver to get IP address through DHCP then I get status “Offered” in DHCP Server menu and in log I get
dhcp1 offering lease 192.168.50.23 for 00:A0:DE:87:35:B1 without success
If i set IP manually on receiver then I still cant access it from my network (cant open web gui) and receiver also don’t see my DLNA server. If i try to ping it both from my windows pc or from WinBox i get 28-32% of packet loss. I already tried:
- 2 different network cables. Both of them work OK with other hardware.
- Reset receiver to factory defaults.
- Upgraded receiver to latest firmware.
The most weird thing that if I connect receiver directly to PC and assign IP address manually on both PC and receiver then ping is OK and I can easily access my receiver web GUI, so everything works as intended. Problem is clearly in Mikrotik and I don’t know what to do. My ROS config is very simple eth1 - WAN, eth2 и wlan = bridge1, eth2 is Master port for eth3-5, no filters, rules.
Update: I’ve been playing with Ethernet port configuration and managed to connect receiver on 10Mbit/sec Half duplex. If I set full duplex even on 10Mbit/sec then I get errors.
RX Broadcast: 2927, RX Multicast: 6664, RX FCS error: 1006, RX Align error: 1068, RX Fragment: 5515
To prevent fragmentation I’ve lowered MTU to 1472 but I’m still not OK with running low speed ant not being able to use Auto negotiation.
