Have this buy because a friend who is familiar with the matter, Linksys has recommended. The installation is very easy as long as you have a PC at hand. Very clear, very quickly. The unit was ready for use in less than 3 Muniten. The radio performance is good, but not outstanding. In any case, sufficient for two floors and 200 square meters. Processing is top, stability so far also. A strong buy recommendation but a half-star deduction for the transmission power, the antenna with external still might be a bit better. That the router has no parallel dual-band, it should be clear that's not worth a deduction. Who wants a corresponding feature, just needs to buy an AP who can.
