Hi,

i've bought 2 identical Archer C2 Router as Access-Points.
Firmware Version:0.9.1 4.1 v0032.0 Build 160512 Rel.40318n
[B]Hardware Version: Archer C2 v1 00000002

I've connected them like this:
German Telekom Speedport Internet-modem in the basement. From there, one LAN-cable runs to my bureau and one to my living room.
I've set up one Archer in the bureau and one in the living room.

To use them as Access-point i used this instruction: http://ch.tp-link.com/faq-417.html

Both access-points have been working just fine for a couple of days.
But yesterday the living room - AP lost it's connection.

I pushed the "WPS/Reset"-button for several seconds to perform a complete reset, because I couldn't access it with the IP-adress I gave it.
After that, I used the http://ch.tp-link.com/faq-417.html - instruction again to reconfigure it.

But now I cannot get a connection any more.
The cable and speedport are ok, because when I connect my laptop directly to the LAN-cable in the living room, I can access the internet.

First, I thought the problem might be that the Archer doesn't get any DHCP-information. In the logs I can find:

1	2016-12-10 08:43:41	DHCPC	Notice	Recv no OFFER, DHCP Service unavailable
2	2016-12-10 08:43:38	DHCPC	Notice	Send DISCOVER with request ip 0.0.0.0 and unicast flag 0
3	2016-12-10 08:43:35	DHCPC	Notice	Send DISCOVER with request ip 0.0.0.0 and unicast flag 0
4	2016-12-10 08:43:30	DHCPC	Notice	Send DISCOVER with request ip 0.0.0.0 and unicast flag 1

But I just checked, that I can find the same log entries in the Archer in the bureau, which is working fine!

Any ideas?
