Boost Wi-Fi and T3200M Firmware Update

I had to redo my local network yesterday, and as such had to add my 3 wifi boosters again. One had to be hardwired, and 2 additional were synced wirelessly. When using the local networking between my computers, one directly connected to the actiontec t3200 and the other computer connected via the wifi booster, I am acheiving local transfer speeds of 475mbps. Very satisfying in my opinion. I read long ago, that the wifi boosters were limited to 144mbps transfers, but when one of your devices is connected to the actiontec t3200, the speeds are much greater, all within the local networking, no internet.
