I'm experiencing the same issues on hardware version V3. Updated the firmware today (v3.0.1 Build 20171117 rel. 57008 (US)) hoping to resolve it, but given the other posts in this thread, I have my doubts.

The router worked very well for the past two months I've had it, with intermittent drops of WAN. Out of nowhere, WiFi stopped working and I had to reboot the router to get my devices to connect to it once again. There were a couple times where I was able to do so through the web interface, but lately, I couldn't even connect to that. Wired LAN worked fine when this happened. However, when I came home from work today, both wired and wireless LAN were down, and I had to reboot the router using the power button. This has become a daily routine, and at least once I've had to do it twice in a single day. I'm suspecting something may be causing high CPU or memory usage, but it's hard for me to tell for sure.

Wireless clients:

5GHz:

* Nexus 7 (2013)
* nVidia Shield
* Google Home
* HP 2710p laptop

2.4GHz

* Two WeMo switches
* WeMo crockpot
* Secondary router in bridge mode
* Chromecast Gen1

Wired clients:

* Philips Hue bridge
* Two computers

Latest update from me, I turned off most of wireless devices (Chromecast etc...), the only thing left was 2 phones: a Nexus5x and Pixel2... and it died overnight. I still can't get more than 12h without having to reboot sometime way less than that.
I did notice that the CPU goes to 100% on the router, maybe a bug with an active loop?
Anyway the replacement hardware I received didn't help... I'm tempted to re-open a ticket or maybe flash it with dd-wrt to see if it is software or hardware...

Pretty sure there is not a dd-wrt version for this hardware. I looked on the DD-WRT forum and don't see this device supported.

I am having all of the exact same issues as everyone else in this thread. I have had the router since the end of September of this year and it have had no issues at all until mid December. Like everyone else, wireless devices either get kicked off the network or won't rejoin when coming back home. Wired devices seem to keep working for a time. The administrative page is also inaccessible when things go bad.

I have hardware v2, US model, on the latest firmware build 20161130 rel.64463. I have factory reset multiple times and re-flashed the latest firmware twice. Since the problem popped up, the time between necessary reboots has decreased from ~12 hours to ~2. I pulled out my old router yesterday and started using it again in place of the c1200 and have had zero issues whatsoever. I have two 2nd gen chromecasts, a google home, google home mini, and two google pixel 2's all connected to wireless.

I am on the verge of simply returning this to Amazon....Has anyone who has put in reports to TP-Link heard anything back from them?

Archer C1200 v.1 // 1.1.1. 20170706 rel. 65715 (EU)
Here is my update: I've moved from WPA2-PSK to WPA-PSK in both 2.4 and 5 GHz.
Now the router is stable for the last 20 hours.

Same issue with my AC1200 V2
2017-12-29 00:18:38
Same thing has been happening to me for the past week, I have the AC1200 V2, and I have to reset my router every morning in order to connect to devices, super frustrating, router is only a few months old and worked fine for the first few months, but now is having this annoying issue, firmware is up to date, no response form tech support...

I have been in constant contact with support. I have tested a few beta firmware and I am still experiencing the issue. The problem makes the router hang/freeze (think BSOD type) and a reboot is needed to resolve it. Maybe a memory leak somewhere.

I thought dd-wrt is not supported on the archer c1200? I remember checking last month and I did not see anything for it.

I've been working closely with tp-link engineers and the 8th beta of firmware they provided to me last night seems to have resolved these issues.I'm sure a production release will be available soon after they finish QA.
