hello i have 2 internet connections at home and looking around i found that i can combine them using a mikrotik router and this is the one that i bought
MikroTik RB941-2nD RouterBoard hAP lite 2
however i have no idea how to set it up and what to do exactly so can anyone with free time help me out 
Also keep in mind that the 941 is not very powerful.
All the mangle rules and routing marks will hog a a fair bit of cpu, it should be good for about 70mbps aggregate throughput maybe more
I would even expect less than that. Significantly less,maybe around a half.
