I replaced my 6-year-old TP-Link TL-WR1043ND with a Gigabit Ethernet 802.11ac router bought for 105 CAD (shipping included) from Dell this week.
Wireless range seems to solve the connectivity problem of one of the clients I was experiencing with the previous router. For reasons I never understood well, at times the client would have huge packet loss and even disconnect, even though it is 1 decameter from the router, no other wireless device was active and other houses a several meters away from ours. With the Archer, the worst path has a 0.01% packet loss.
The interface is satisfying (although English-only until you install the May 2016 firmware update, since the router came with the 2015 firmware!). It is simple and the feature set includes everything I need.
I accidentally pressed the reset button while relocating the router. As noted in this TechHive review, this button could easily cause an inadvertent reset, but I did not push it long enough for that.
I chose this router partly because of its comparatively long warranty (2 years rather than the usual 1 year). I am mostly surprised to find no specification of warranty in the box. The box contains 2 quick installation guides (1 multilingual, 1 English-only), 3 prints of the GNU General Public License (versions 1, 2 and 3), a copy of the GNU LGPL, a superfluous "Resource CD", but no mention of warranty.
