Use Google image search, no one's going to do the leg work for you (I sincerely hope).
Stay away from the WRT1900/1200, support for the wifi hw they use, is so so ....
Amount of antennas doesn't really say anything about the wifi performance, some vendors even add dud external antennas, to have the device look "more impressive".
I also know that the number of more antennas does not mean an increase in Wi-Fi range!
But you can't get anywhere by searching on Google because the Wi-Fi router's range is completely experimental.
Linksys EA8500 is a pretty old router, pretty good but if you find the Netgear R7800, go for it.
Both are ipq806x, but the R7800 is almost unbreakable and very capable.
What is your Download and upload capacity?
look, on my side, I also have the E8450 and there is no antenna outside and if I use R7800 without NSS build, the E8450 was more powerfull on 5ghz. Also, what do you want , what do you need?
Considering that the area of my house is about 500 meters. I'm looking for a router to put in the middle of the house and its waves reach everywhere, but none of them are more than 30 meters, in the best case, it doesn't work even with a complete parameter change!
There is no router that has an antenna range of 100-200 meters. Or at least close to these numbers?
