Windows 7 Network Bridging

When setting up my SageTV server, I needed to move the server from the office to a spare room to get better over the air reception. In doing so I had to alter my network layout, so I had my Ethernet over power link running from the server to the HD300, and then a wifi link from the server to the rest of my network.

I was having all sorts of problems getting the routing correct, when I noticed Windows 7 has a bridge device option.

(shown turn off above as this image was captured on my work laptop)

When I click this option it said something like: ‘You need to select two devices to bridge’, good point. So I selected the Ethernet and Wifi at the same time, right clicked, and bridged them.

Now the HD300 can see the internet, and it all just works (this was done months ago) and it is still just work.

So Windows 7 earns a “just works” point, well done to the OS team there.

Network Testing with Laptop

A few weekends ago I was testing my new SageTV setup with my laptop.

I had the network in one configuration, and I wanted to move things around to get better reception. Before I moved the server and aerial, I took the Powerline device to different rooms in the house to test. I ended up only getting 9.4Mbps in other rooms. I then noticed my laptops Ethernet connection was at 10Mb, assuming something was wrong I forced it to 100Mb full duplex and only got 17Mbps throughput. Assuming this was due to some cross circuit performance problem I tested around the house, and ended back in the office, and with my laptop on the same 100Mb switch as the server, I was still only getting 17Mbps.

After banging my head for a while I put the network connect back to auto detect, and plugged the laptop back into the power cord and ta-da, 94Mbps to the server.

Thus for my Dell Latitude E6400, with Windows 7, on battery, the Ethernet runs at only 10Mb. I remember Windows XP having an option for reduced Ethernet speed on battery, but cannot find it under Windows 7, it just seems to always be on.

Thus now with power cord in hand, I found that the room I wanted to place the server gets 45Mbps to the TV, so I proceeded to move everything, and over-the-air TV is wonderful.
