Vlan's Double Bandwidth Useage

We just moved from EOIP to VLan for segmenting our network, for the purpose of showing this issue this is how our network works right now

Laptop —L-----Router 2-------W-------Router1----L-----Router3—L----Server

All links are L= Ethernet, W= Wireless

The laptop and server are connected via VLAN’s and Bridging

My Laptop is attached to the “OnBoard” interface in this picture, i am pulling a 700mb Rar file over HTTP, Firefox reports useage at ~2900Kb/Sec, Which is very close to the reported 24mbit used in the picture
2 900 kilobyte = 22.65625 megabit

On the Wireless VLAN interface you can see that useage is correct at ~24mbit - What is strange is that the Radio interface reports 2 x the useage, 48mbit - it seems that this is correct as when we used EOIP tunnels i was able to do this test at 5000kb/sec+ speeds.


Anyone got any ideas as to what is causing all VLAN traffic to double?
