Hi,

I'm not able to reproduce it on TP-Link Archer C7 v5.

> Attempting to use the hAP ac lite model RB952Ui-5ac2nD with the 5GHz
> radio0 802.11ac seems to be unstable and consume available memory.
> This is only enabling radio0 with no other changes and bringing wifi
> up/down to reproduce.   Am I doing something silly, or should I submit
> a bug?

uptime > /tmp/wifi.log && \
cat /etc/openwrt_release >> /tmp/wifi.log && \
uci set wireless.radio0.disabled=0 && \
uci commit wireless && \
wifi up && \
echo "up: $(free | grep Mem:)" >> /tmp/wifi.log && \
sleep 120 && \
wifi down && sleep 1 && \
echo "dn: $(free | grep Mem:)" >> /tmp/wifi.log && \
for i in $(seq 1 10); do \
	wifi up; sleep 15; echo "up: $(free | grep Mem:)" >> /tmp/wifi.log; \
	wifi down; sleep 15; wifi down; sleep 1; wifi down; sleep 1; \
	wifi down; sleep 1; echo "dn: $(free | grep Mem:)" >> /tmp/wifi.log; \
done; cat /tmp/wifi.log
