Hi,
I have a network as follows:
1x TL-WR941ND connected to the WAN and the central point of my network (CED).
1x TL-WR941ND in client mode, in my laboratory (LAB).
1x TL-WA830RE to extend my home network (REPEATER).
1x TL-WR702N to connect my TV, XBOX360 and TV decoder (NANOROUTER) via a switch (TL-SF1005D), plus various other wireless client (smartphone, tablet, notebook)

My problem is as follows:
When I put the network under a high load (file transfers, HD video streaming), for some reason the network crashes, forcing a complete restart of the various nodes (repeaters, client, etc.).

Investigating the logs, I noticed the following items:

CED:
[875410.730000] ath: phy0: Failed to stop TX DMA, queues = 0x004!

Also, going to check the file
/ sys/kernel/debug/ieee80211/phy0/ath9k/reset
this is the result:

CED:

Hang Baseband: 2
Baseband Watchdog: 0
HW Fatal Error: 0
TX HW error: 0
Hang TX Path: 5
RX PLL Hang: 0

LAB (CLIENT MODE):

Hang Baseband: 0
Baseband Watchdog: 0
HW Fatal Error: 0
TX HW error: 0
Hang TX Path: 23
RX PLL Hang: 0

The network is set in:
NG-MIXED
Channel width: Dynamic 20/40
Channel: 6 (most free)
Extension channel UPPER
Protection RTS / CTS
TX / RX Chains 1 +2 +3
WPA2 personal / AES

DDWRT version CED / LAB:
Release: 31/12/12 (SVN revision: 20453)

the WA830RE WR702N and have the latest version available stock.

Any help is appreciated, thank you all in advance.
