Model: Archer NX200  
Hardware Version:
Firmware Version: 1.2.0 3.0.0 v60e0.0 Build 250725 Rel.73467n

After updating version 1.2.0 3.0.0 v60e0.0 Build 240822 Rel.76438n to 1.2.0 3.0.0 v60e0.0 Build 250725 Rel.73467n slow internet. I did a RESET, it doesn't help. Following the advice of the forum, I changed the DNS server to 8.8.8.8. , after the change it worked for about 12 hours. Again it doesn't work normally. I tried to leave only the 5G internet connection, but then the internet doesn't work at all. Internet in Latvia, operator "BITE"
