    I have a BEFSR81 Model 1 Router that I'm trying to upgrade to the latest firmware release befsr81v2_fw.bin

    I am using Windows 7 64 bit and Java 1.6.0_30 and getting the following error below with windows firewall disabled

    any suggestions?


    Java Plug-in 1.6.0_30
    Using JRE version 1.6.0_30-b12 Java HotSpot(TM) Client VM
    Uploading ...

    Wow today I just upgraded my befsr41 and all went smooth. Perhaps its the wrong firmware file firmware bin says befsr81v2 V2 and you have a version 1.

    It's the same version for Models 1 and 2. I don't believe it's even getting to that point my guess it's related to Windows 7
