I was wonder if its compatible with Asus Rt-n10+ B1?
Im very new too this.
Sorry, the RT-N10+ B1 isn't supported because the processor it uses isn't supported by TomatoUSB. The previous version (the one without the "+ B1") used a different processor that was supported. If it helps it looks like the RT-N10+ B1 is supported by DD-WRT.
Yes, RT-N10+ B1 support DD-WRT.
