It doesn't work.. it has a problem. It turns on and you enter the menu, but until there, it behaves as if I haven't plugged in the LAN cable.

Kids, I have it for 2.5 years, many times it gets stuck and shows on the phone that you are on the internet but the access point is not. Also, many times it drops the speed too much for no reason, while if I connect to the router, the speed is normal. I don't know what else to do, but it's not worth it.

For its price, it is stable with OpenWRT 19.07. With adblock-basic and travelmate, it does its job more than enough.

I wanted a single WiFi in my house. That's why I got it, but it didn't cover me because I had constant interruptions in the WiFi. Maybe I haven't made the right settings. In the access point I have now, I have two WiFi networks. (WiFi 1) and (WiFi 1 plus). It works perfectly fine there.

Sometimes it needs a restart.
When I used it to view my home camera, it would freeze.
I had to put it somewhere else.
Also, when I used it for audio airplay, it would freeze again.
I had to put it somewhere else.
Give an extra 5-10 € and get the 901 that I have, it hasn't created such issues

Very good product, with a very basic interface. It doesn't do fancy things like iptables routing, firewall, cron, etc. However, it supports well-known good firmware. Although it also comes with a locked firmware, it can be unlocked with command injection. It can support OpenWRT and DDRT (be careful, if you're not Linux geeks, you should look for one that also has luci). With this small upgrade, it is excellent.

Detachable antennas, functions, management. It is the best you can buy for 25-30 euros.

When he doesn't want to connect, he doesn't connect with anything, reset, restart, set up again, nothing, he will only connect when he wants to, useless product.

I made the stupid mistake and bought it 3 months ago.
For most TP-Link products, there is still no patch for KRACK, which poses a security risk for you.
Stay away from WA801ND at least until they release a patch for KRACK (if they ever do)

I put it to send data from a photovoltaic. I put it once about a year ago and since then I forgot it exists... It has proven to be very reliable, stable, and without any problems.
update 30.10.2019: it continues to work perfectly.
