Not a bad product, but you can find better.

Take it only to a private house (it will cover 2-3 floors of a block house) if there are more than 1 of them, change each individual IP from the standard one, otherwise pings grow strongly after a while) In the N mode, only it works stably and quickly in others worse. If the devices are new and they do not work much, it will be very good, but if these are Chinese tablets and old phones, then how lucky.
They took it because of the urgency (so of course they would have taken UniFi, but they had to wait 2 weeks and the budget would have tripled) to the hotel 2 per floor on each floor of 5 floors copes with their work, but periodic hangs and glitches are removed. load on points 2-15 clients
Tried different firmware and different dances with a tambourine - glitches remain.

Pros

Relatively inexpensive, good coverage area (when replacing standard antennas with 8 dB antennas), simple setup, PoE - sometimes it helps a lot when there is no way to pull power. When there are few devices (1-5), there is no wi-fi interference and power surges in the network, it works perfectly at high speed without glitches for weeks. If you turn on the N mode only, then the stability and speed of work increases significantly, especially in pings.

Cons

Hang steadily! Up time is a maximum of a week. Almost in all modes of operation. They don’t like crooked Chinese tablets and old laptops, switching to mode b, from which pings begin to grow fiercely, if there are such devices on the network, iPads and iPhones with old firmware and some android devices cannot normally connect. When N and g devices work simultaneously and some of them at the border of the reception zone, pings grow very strongly for everyone, even for those who stand directly under the point (it might help to have the gn mode, but there is only bgn in the tp link or everything separately) If devices with the wrong password try to connect to the point and do it for a long time, pings grow at the point after a while in this mode, if several active clients are connected, the point hangs the configured Watch Dog helps every other time. When there are a lot of points nearby, even on other channels (1,6,11 as it should be), the pings grow, stability is lost (on the Linuxus, in the same conditions, everything is perfect with a lower (!) signal level than from a TP link)) Hangs from power surges more often than d-link 1360 (and it is a very unstable piece of iron that works as it wants) Watch Dog (auto-reboot when hanging) is apparently not implemented in hardware, it rarely helps to ping a remote server. the Wi-Fi module mostly hangs, but we do not have stationary wi-fi clients. Sometimes it hangs so that the point is no longer pinged over the LAN, but Watch Dog does not work. If there are a lot of them, you will often have to run to pull from the outlet. 12 volt PoE is good only at short distances of 1-15 m of high-quality copper cable, wafer power and stability of operation drop by 5 m of steel. fixed for 2 months of work 2 deaf hangs that were not helped by a power reset, but a reset and reconfiguration helped In repeater mode, it is buggy (ping growth, does not connect some devices) if there are more than 1 clients.
