i double checkd the first gen. Google mesh does have dualband, and i needed to go check what the heck i bought the new router for, i found out, that i bought it for gaming for my 13 year old son, so i changed to TP-link Archer AX73 router not the netgear, i had before ( i am so embarrassed my son had to explain this to me) and he said there were no limits to his wrath if i changed back :P so better not touch anything. Thank you all for the help!
