Thanks for the quick response.
A couple of things… The MBL is configured to use a static IP address so I’m not sure how it will get MTU from the DHCP server in those cases. Perhaps that’s an oversight in the firmware, that there’s no default MTU for statically assigned IPs?
The SKY HDD box is not a modem.
My setup is as follows:
Netgear DG834GT ADSL router courtesy of Sky (4x 100Mbps switch ports)
Netgear WNR3500L Wireless N router (4x 1Gbps switch ports)
The wireless is disabled on the ADSL router. It’s just running the ADSL modem and acting as the gateway for the network.
The WNR3500L runs the wireless so I can get Wireless N, and my MBL and WDTV Live are both connected to the 1Gbps switch on the WNR3500L.
I’m not using the WNR3500L as a router. It’s simply uplinked to the other Netgear via one of the switch ports and acting as a wireless access point and four port 1Gbps switch (I bought it for the Wireless N and Gigabit to connect the MBL).
So the whole network runs on a 192.168.0.x/24 network. The ADSL router is 192.168.0.1 and acts as the DHCP server, DNS server and gateway. The MBL is on 192.168.0.100 and the WDTV Live is on 192.168.0.101. My WNR3500L acting as the 1Gbps switch and Wireless N access point is on 192.168.0.254.
I have two Sky HD boxes connected into my free ports and they are picking up IP addresses from the DHCP server. My DHCP scope does not extend anywhere near the addresses used for the MBL or WDTV Live.
So, in short the MBL is connected to a 1Gbps switch using a static IP address
For those others who are interested, the rollback never worked. It appears that using the GUI or SSH sessions that you are restricted from rolling back to a previous version. Incredibly frustrating and suc ha major oversight by WD as they’re assuming all new firmware releases don;t have any bugs which could require a rollback. Only platform in my 12 year IT career that I have seen which prevents a firmware/software rollback.
Any more tips?
