At the moment it is quite hard to judge, if it is a problem of Apple or TP-Link, but at least it seems that the combination of both is not working correctly at the moment.

Even a beta firmware of Archer C7 is not helping as it seems... (see here for my story).

Hi All,
I had same the issue with my APPLE MACBOOK and fixed the problem by DISABLE UPnP.

This appears to have worked for me!
However, it still annoys me because this is a workaround. TP-link needs to get on this in a proper firmware update.

My C7 is quite new, but the connection-rate is getting lower and lower. After resuming from a standby (Macbook Pro late 2013, AC built-in), I only have a 7 MBps-connection but no datatransfer at all. 2.4 GHz works fine.

When do you update Revision 1.x -- and what's the difference to the HW-Revision 2.0?

Firmware Version: 3.13.33 Build 130729 Rel.56122n
Hardware Version: Archer C7 v1 00000000

Settings (Overview):
Wireless 2.4GHz
Wireless Radio: Enable
Name (SSID): CasaDeLaSol24
Mode: 11bgn mixed
Channel: Auto (Current channel 6)
Channel Width: 40MHz
MAC Address: (secret)
WDS Status: Disable

Wireless 5GHz
Wireless Radio: Enable
Name (SSID): CasaDeLaSol
Mode: 11a/n/ac mixed
Channel: Auto (Current channel 36)
Channel Width: Automatic
MAC Address: (secret)
WDS Status: Disable

The both images shows, that there's only 7MBps left, but the signal is perfect... On the next morning, I fixed it with restarting the router.
