for unifi vip5/10 users, just to share...

i watch mangotv and hitv quite a bit besides xbmc.
i used to find many shows in mangotv lagging and couldn't get hitv hd stuff smoothly consistently even on ethernet.
recently i changed from orig dlink router to this asus rt n12hp router (rm199):

result has been excellent. ethernet and wifi both improve a lot, very pleased.
on ethernet, i can get most stuff on mangtov smoothly, incl hd stuff.
on hitv, u can select from 3 options: "clear", "high", "super" definition. i can now get them in "super hd" (=1080, i think) smoothly. can see from the yellow buffer bar it is good. nice!
on wifi, results quite close to that on ethernet.

while we discuss and agonize a lot over chipsets, firmwares, app versions, dns, proxies, nominal broadband speed, etc., don't overlook this router issue. i am convinced the orig unifi router is very poor. good news is a rm200 replacement router giving stronger and more stable signal connection will change all that to deliver much superior results.
