have listed above the THREE most powerful (number of antenna is the give-away) wireless routers, from ipTime’s line-up early Summer 2013 for specification comparison . I should note one welcome add-on, concerning manufacturers revealing actual chip used : it didn’t used to be so, but their own effort from 2012 to sell later models as an improvement of the older . to-date : ipTime notes the earlier N8004R is still the reigning model in terms of power and far-reaching extent, while the later 2 new models have added NAS capability, with A2004ns : 802.11ac on top of that . and as I have found out to be true too .
note a big selling-point accentuated by its manufacturer is A2004ns’ larger electric adapter, to power potentially connected USB disk .
although the three top-of-the-line models introduced here, whose 3~4 antennas will cover quite a large open-space office, a medium-family apartment is the maximum for domestic residences . as listed on our wireless speed page : numbers drop suddenly after entering the third room then door closed .
Korea Tech BLog is updating ALL wireless speed review test on a /single/ page on top menu, so will be there eventually . but for now, the old experience still hold true from the days of business trips on the belated Korean bullet train KTX between the Capital of SEOUL and the Port city of Busan or Pusan, which run diagonally almost to the full length of the Southern Peninsula – it was the time of (technical) stone-age modem-speed with USB-sized dongles attached to your laptop or notebook – the older model is more stable with slightly longer reach, as the new shows irregular drop-outs while a tad faster . so unless you absolutely NEED NAS which I currently note on ipTime’s ipDisk Page on top menu : again quite um, no actually notoriously unstable, no need to upgrade just yet ~
