Hi,
I have bought recently a c1200 on Amazon,

Hardware : Archer C1200 v2.0
Firmware : 2.0.0 Build 20170206 rel.46023 (EU)

And i have the same symptom, once or twice a day, the wifi was visible but not respond, if i have a pc already connected, the web interface are down too.
The only solution, i reboot the router.

The router it's slightly warm, but not hot or burning.

Thank you!

EDIT :

I have about 6 wireless devices and 1 wired (nas)

Yes same issue with the new hardware, started freezing on day one and requiring reboots.

Archer C1200(EU)_V1_170706

Hi

I have the same router for a few months and have similar problems with different mobile devices that disconnect and connect daily (2 Android mobile phones, and 2 laptops), on both 2.4 and 5 GHz bands. The only way to solve the problem is to reboot the router, but it works only for a few days.
A full reset to factory default make it work again for a longer time, but the problem happens again

I hope a new firmware will solve rapidly this problem. I'm disappointed with the stability of that router.

Hi,


I have TP-Link Archer C1200, HW: v2.0, FW:2.0.0 Build 20170206 rel.46023 (EU) since 02 Dec 2017.


First few days it was running fine but last few days I had to power restart the router 3 times as it was hung / freezed / dead.


WiFi 2.4 & 5 GHz were visible but unable to connect.
LAN connected but does not receive IP from DHCP server. Manual IP entry does not help.
Unable to reach Router interface from the local network, no ping, no access from my external IP, unable to get system log.
Router has all lights solid green.

I gave up and asked for a refund, there is obviously a huge problem with the V2 of this router.

I have v2 of this router and have the same issue. Connected wifi clients lose access to the router more than a few times a day. The only way to fix it "temporarily" is to reboot it. I tried disabling the 5Ghz wifi and it seems to be much more stable now.

This router has turned into a major disappointment and a pain after reading the positive reviews. The most recent ones from November to December on Amazon complained of the same problem. Maybe it's a bad batch? It doesn't matter because I'm returning this and getting an Asus instead.

I had a chat with a TP-Link support however their advice was just to factory reset the router and set it again, which I think won't help.


When I start downloading 1 torrent task in Bitcomet, the router's CPU load goes to constant 100%. In this case I am able to login/logout the router management page. When I start more torrent tasks simultaneously it blocks access to the router's management page/UI (unable to login, ping is ok =1ms).


In normal operation the router's CPU load is 30-50%. When transferring file to local NAS, the router's CPU load is 80-90%.


I am using laptop connected to WiFi 5G AC network of the router. Tried with all browsers Chrome, Firefox, IE. ISP limit speed is 20Mbps and torrent download speed is 2.5MB/s which leaves plenty of bandwidth between laptop and router.


So I think downloading torrents loads the router's CPU and that might cause the freeze and router blocking.


Last night I started BitComet and left it downloading and later the router died again. That makes me think problem might be something with torrent connections.

Do you have such observations? When do you think might cause the router to die? What software traffic do you have when your routers freeze? Anyone managed to get the logs?


I will also return this router to retailer as it is unstable and will change it for ASUS RT-AC1200G+ (same chipset and components inside) but hopefully firmware would be more stable.

I have exactly the same problem. Any update on that issue. It's pretty bothering to restart the router everytime...

Hi,

I have turned off 5GHz WiFi and I am using only 2.4GHz with 13-15 wireless clients and 5 wired with heavy torrenting and internal transfers laptop - NAS for two days and no router crashes for the moment.
Router CPU is constantly 100%.

Please try and revert if that helps.

I'll do the same and see if it fixes it.
