MTU change or confirm/verify
E.g. T-Mobile 5G Gateway refer https://community.t-mobile.com/tv-home-internet-7/way-to-change-mtu-on-router-35132 - the MTU for connected WI-FI router will work best if set to 1420, whereas most such devices (including Eero???) default MTU is 1500.
Would love for all Eero routers to confirm or automatically change MTU as needed, or be able to be set by the Eero owner.
There should be maximum data efficiently if the Eero router will match the MTU of any gateway not just T-Mobile.
