DNS Resolution phone = yes home internet = no ???
It makes no sense how BOTH my iPhone and T-Mobile gateway connect to the SAME 4G and 5G cells yet DNS doesn't resolve over the gateway. I can ping major DNS server IPv4 addresses and get a response o...
OK so there was some issue with DNS that T-Mobile was having but they seem to have resolved it yet again. Nothing advertised as to what the cause of the behavior was but it works again. Using the workaround to set the client DNS vs allowing the gateway IP works good.
To Summarize: Power Cycling several times it just presented me with its same 192.168.X.X number but after using the Reset button it used a new IP and resumed DNS connectivity.
I have been running into this issue more frequently this past couple of months, at one point the only option the T-Mobile presented was to do an RMA of the 5G home internet device. Just recently discovered through trial and error that if you're encountering this problem, power cycling the T Mobile 5g home internet device does not reset its own Automatic DHCP settings (at least it did not with my device). To accomplish this I actually used that tiny Reset button on the back, just a regular press and release, did not factory reset. After doing that I noted that the device's home network IP address changed and it was able to successfully reconnect to full DNS networking. From what little I know about network engineering I would guess some sorta lease information just does not trigger a reset as it should when the lease information is expired for your device on their network. I have gone entire weeks without issue, but at minimum it seems to take at least 24+ hours before it happens again.
