Juče sam merio dva brzinu mreže preko dva access pointa, i iskreno rečeno razočaran… Meni wirelessi uglavnom lepo služe svrsi, i lepo rade (ponekad i ponegde neki pravi problem, ali se to da rešeti), ali da su ovoliko spori, toga nisam bio svestan sve ove godine 🙂 Opet možda ja negde grešim…
Mereni su stari Linksys WRT54GL (stari poznati znalac svih linuxaša) i TpLink WR842ND (opet AP linux friendly, ovog puta sa OpenWrt firmwarelom u sebi). Merenje protoka radjeno sa mog Lenovo EDGE E330 laptopa, Intel Wireless-N 2230.
