T-Mobile Home Internet - Setup Fixed IP

I totally agree with many of the pejorative comments in this thread. The T-mobile home router seems to have all the capabilities of a rock. I doubt that there is another router that you can purchase which does not allow address reservations. It is unacceptable for all ones home devices to be constant switching IP addresses.

@mrmox read the above reply of mine… only way it's going to happen with T-Mobile. VZ dunno

Yes T-MOBILE PLEASE fix this!  Anyone know if verizon does this?  they are advertising a lot.

The Nokia 5g garbage can will not handle what is mentioned above. 

I have business and used they gray home internet. I asked about static and had to get an inseego fx3100 from them. less than 5 bucks for a static ip a month. inseego gives you major functionality as well as DHCP

rockstr, that's not the issue. some of us want the router handing out DHCP addresses to keep assigning the same ips to some devices. I just power cycled and 2 security cams came back with new ips, so now I have to reconfigure the NVR. This is why I will be dropping Tmobile home internet. it's just not ready for prime time. with other solutions, I won't have to buy my own router to deal with what should be a standard feature. bye bye Tmo.

You can get a an additional cost fixed external IP address with a T-Mobile Business Internet plan, and some users have gotten fixed IP addresses by using various VPN services.

Don't blame the router for this (although there IS a lot to complain about in the way they've locked down the routers in firmware).It's not the router, it's the service outside your house, after it leaves your router, that causes the inability to get a fixed IP address via router settings. It has to do with T-Mobile's infrastructure, using 464XLAT and CGNAT to translate IPv4 addresses into IPv6 addresses to move data over their network and then translate it back to IPv4 addresses at the other end (and again on the return trip).

Getting a fixed IP address is going to cost extra, whether you use a T-Mobile Business Internet account with fixed IP address or a third-party VPN service with fixed IP address capability.

Or, t-mobile could fix their crappy home internet router so it is usable. Every other router on the market is more flexible and comes with the ability to configure the settings. What crap.

How can I set FIXED IP's? I need fixed IP for my printer and cloud device, because with DHCP, every time I restart devices, with random IP, I lose mappings and have to refresh settings all the time.

This is why you typically give devices a name and you point to the name instead of the IP address. The DHCP lease may be too short, so if any of the devices are disconnected past the time to live (TTL) time, then they will receive a new IP address. If you create a network port using the printer name, then the IP won't matter as the DNS will find the IP with the printer name.

The alternative is a feature called DHCP Reservation on most routers. Not sure if the T-Mobile device can do this. If it doesn't, you can find a cheap home router on eBay that has this feature.  Reservation will assign an IP address you reserve tied to the MAC address of the device. So, whenever your devices talk to the DHCP server, it will always get the IP address you've reserved. This is like giving the device a static IP, but it is managed on the router level not device level. 

Instead of another router, you would need a switch.  That would allow you to set static IPs and be able to meet your work from home requirements.

You will need a home router that supports DDNS services.
