5G Home Internet Suddenly Very Unstable And Technical Support Is Essentially Useless

Userlevel 2

Wondering if anyone else is having similar issues.

First, at $50/month for 5G speeds with no data caps, this service is pretty much the best deal out there.  When it is working well, we typically see speeds in the 60+ Mbps down/ 20+ Mbps up which is by far the best performance we’ve ever had at our house.  

Unfortunately, it has recently become the case that it almost never “works well”.  Over the last couple of weeks, we are lucky if we can get an hour a day where it is getting this kind of performance.  For much of the day, it is actually not even usable (we’re talking less than 1 Mbps and barely registering uploads).

The strange thing is that when we first got this modem, it never seemed to be the case.  I saw some forum discussions that overheating might be an issue, but it really isn’t that hot.  Additionally, when it is performing poorly, I noticed that we are getting less than two bars primary and zero bars secondary on the modem.  Again, this previously wasn’t the case.

Sometime rebooting with temporarily resolve this issue, but I am not kidding when I tell you that most days we restart the modem a minimum of five times.  Many times it simply doesn’t fix anything.

Compounding this is the fact that TMobile seems committed to off-shoring their technical support and the quality of this service is so bad it could be a post in itself.  Over the last couple of months I’ve probably called once a week, which typically eats up an hour of my day and has rarely resolved anything.  On three occasions, the representative told me they would call me back and not one has.  Not one.

On the last call, I managed to get a “manager” on the line who honestly was not any better than those who work for him.  His only solution was to downgrade us to LTE even after I told him that we ultimately go the 5G device because the LTE was working very poorly.

Anyway, I’m 99% sure I’m just going to have to bail on this service and go with Starlink which is available in my area.  This really bums me out because when Tmobile’s service is even working halfway decent it is more than enough for us, but “half-way decent” at this point is a dream state for us.

Again, I’m curious if others are having similar issues.  For what it is worth, we have the Nokia 5G cylindrical tower.

I had just posted in another forum.

“TMO has absolutely oversold their home Internet. My service was great for 1 year- slower speeds than Cox, however, the connection was very stable. Over the past 3 months we have ZERO internet from 5 pm until about 10 pm. Called tech support,, the matter was escalated and they are going to call me back. A Supervisor even called me because I am a 20 year customer. What are they going to do -- it is either add more towers or remove customers!

My family members have demanded we go back to Cox. SuperBowl is coming up and the men in my house are not happy so 15 minutes ago I recommended Cox and am just reconfiguring a few things..

I wonder what will happen with TMO. If you think about almost every new initiative they undertake ends because of issues on their end --TV, their original prepaid card, their TV portal, their box. their home router for calls etc --the list goes on and on.

I work from home and cannot deal with Internet that does not work.

The pricing is great which is what attracted me and for just about a year it was good and now went back to Cox and got a good deal. I took the price comparable> The option.I used to have the Ultimate and if anything good came out of this I now know that the slower speeds of 100 down work just fine. I never got anything over 25 with TMO and when it worked it was fine.


My prediction for TMO moving forward -- heavy throttling and new pricing options with data caps”
