TP-Link ArcherC20 dhcp in relayd not work

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi everyone....
I have such a problem, I have TP-Link ArcherC20v1. I made a wireless bridge and DHCP does not work ;( the second c60 router has the same configuration and works and c20 won't ...
I suspect that this is a bigger problem. In c20 there is a mediatek mt7620 processor.
I tried various versions of 18.04, 18.06, 19.07.0, 19.07.6 but unfortunately it doesn't work on any of them ...

if I set a static address on the phone,pc it connects without a problem ...

I'm pasting the configs that I changed

wireless:

config wifi-iface 'wifinet2'
	option ssid 'WIFI REPEATER'
	option device 'radio0'
	option mode 'ap'
	option network 'lan'
	option encryption 'none'

config wifi-iface 'radio1_WIFI_TEST_'
	option network 'trm_wwan'
	option device 'radio0'
	option mode 'sta'
	option ssid 'WIFI TEST'
	option encryption 'none'
	option disabled '0'

network

	option type 'bridge'
	option ifname 'eth0.1'
	option proto 'static'
	option ipaddr '192.168.1.1'
