Is anyone else having problems with a changing IP address?

I’m having issues with my IP constantly changing as well.  I get the same added verification requirements as noted above.  At work I have to give our IT person my IP address for him to enter into the backend of our system so when I try to login it will see my IP address is already on the “guest list” and then grant me access.  Every time the power goes out or I have to reboot the tower it changes.  I’m starting to really feel back having to ask him to yet again enter in my new IP address.  I would really like to know if there is a IP range they are using for my area so I can provide that to my IT person keeping him from having to manually enter in each new IP address - very annoying. 

There's an easy way to fix this. Unplug the gateway, then tap the reset port on the back with a push pin or paper clip. Slide the power switch off then on for good measure. When the top 3 lights are out and the front light is reddish, plug the power back in. When all the lights are green, the gateway should be reoriented to your local area.

All it generally takes to change IP is a reboot.  Still on the LTE box, which takes a little while to fully come back online.  If by chance it isn't down long enough to trigger an IP swap, doing a full power down usually does the trick as that cycle takes a bit longer.

The point is that we are on a system that behaves kinda like a cheap/free VPN service (shared/dynamic IP's with short lease times) and sometimes we will get shot off into left field trying to get us online.

It appears the off-the-wall locations usually happen when congestion has ramped up where we were previously tunneled through.  For me here in Sputh Carolina, it tends mostly to swap between Charlotte and Atlanta... occasionally I might get shunted to Miami or somewhere out west though.

When those further out locations crop up, bandwidth REALLY tanks from the congestion.  Usually take that as a sign to just go do something else for about an hour, then power cycle the modem and hope things clear up.

I keep losing Hulu. I have to call them and enter a new code from my computer. Also, all my financials want to be verified again. My wife is not happy with this, since I have to do this. If it continues, tmobile will lose a customer

This is causing me not to be able to log into my banks that use Netteller becasue the IP is changing mid login. Netteller thinks its a redirect hack. Really annoying.  I have to call tmobile to have the reset everything every time, then it works for a week, then stops.  Going to have to change provider.

Who was your previous ISP? did you have a static IP address? Ordinarily this is something you pay a bit extra for. The norm is dynamic IP, it will change unpredictably. You need a static IP if you are running your own webserver for example, that’s how the outside world can find you (the DNS system will map your domain name to that static IP).

But for day to day internet use I’ve never heard of people needing a static IP address, most home internet plans are by default dynamic IP no matter who the vendor is, Comcast, TMobile, CenturyLink...

The outside world isn’t calling in to you, you call out to external sites and services and for that we use username/password etc to gain access to them.

Where can I see the IP address in the admin UI? (This is the NOKIA Im talking about).

When I do that I get told my IP is “likely” static:

What do you guyes see for that when you visit that site?

My fix is in the last paragraph, but here is some context if you’re interested...

A short lease of my IP address just started happening to me, and I came across this forum. My external IP address is changing once or twice per minute! As you can imagine, this is really inconvenient because many sites check for this and boot the user when their IP address changes mid-session causing the user to login again.

I’m on a Mac, so at first I thought it had to do with the new-ish “limit IP tracking” feature -- turning that off didn’t do anything for me.

I then called T-Mobile and was not able to get beyond the first step of support (he was super nice, just not very helpful -- he spoke to an engineer up the ladder and came back to tell me that there was a difference between static and dynamic IP addresses...d’oh). The issue is not that it’s a dynamic IP address -- it’s the lease time of the dynamic external IP address that the Gateway is throwing out to the world. I was able to see my external IP address change very quickly through a simple PHP script.

(if you’re interested:)

echo ' MyIP:'. $_SERVER['REMOTE_ADDR'];

My fix was to sign up for an external VPN (I chose protonVPN, but there are many others out there). This has fixed my issue, and I hope it’s helpful to someone else who comes across this discussion.

People above not understanding the problem are not reading it carefully. This is NOT about having a static IP. Its that the IP is changing as frequently as every few SECONDS. The wreaks havoc with many sign ins as if your IP changes mid-transaction it invalidates the transaction and you CANNOT LOG INTO THINGS YOU NEED TO. I can solve it with a VPN, but that’s a pain. Many services block IP switching mid transaction as a security measure and in other cases programs loose their connection to a server mid application causing errors. It is entirely unacceptable service from an ISP.

This may give you a static internal (LAN) address, but it won’t affect your external IP address that the rest of the internet sees. That happens between the gateway and T-Mobile’s WAN, and due to the nature of the TMHI infrastructure, that’s gonna change when it’s gonna change. Forum members report that if you get a business account, you can pay extra for a static external IP address, but there are some downsides to business accounts; e.g., some people have reported that they block streaming entertainment services. 

That said, changing IP address every few seconds is not the “normal” IP address change we typically see. Those changes usually occur less frequently, and often when something changes, like rebooting the gateway or the gateway changing 5G/LTE bands. Problems with lease timing, as suggested above, could be at fault, but renewing a lease every few seconds is abnormal behavior, and because our gateway firmware is so locked down, we can’t get to those settings.

Contacting TMHI service by phone is a crap shoot, and more often than not gets someone using a script who doesn’t really understand telecommunications very deeply at all.  Search on this forum for T-Force via Twitter or Facebook--people seem to have much better luck contacting service that way.  I now avoid the phone and go straight to Facebook chat with T-Force. The reps I connect with actually do seem to understand telecomm concepts, even if they can’t always resolve my issues.

I am having a different, but IP issue non the less.  My new T-Mobile modem shows one IPV4 IP address, Gateway IP and DNS IP.  However, Whatsmyip shows a completely different IP.  Any ideas on how to ask them to fix it? I am looking at switching from DSL, where it always shows the same for both DSL Modem WAN Public side and WhatsmyIP.  Typically, only changes with a reboot.
