Security cameras not connecting to T Mobile Internet?

Finally got it to work again after changing to TMHI and buying X9 camera doorbell.  Steps you could try that worked for me after numerous tries:

1. In T-Mobile Home Internet app create a new Network. Give it a name like "My24ghz"
2. Set Frequency Band: 2.4 ghz like the Network Name suffix suggests.
3. Set the less secure Security option: WPA: “WPA/WPA2”.
4. System will Automaticaly set encryption's mode: “TKIP & AES”.
5. Set Hidden: “OFF”
6. Save and the restart Network Gateway.
7. Install app “X-Smart Home”
8. Open app on you smartphone and create new sign in or use guest login.
9. Turn phone Bluetooth on.
10. Take pictures of new accounts and passwords. This is in-case you delete app and data and later need to re-install and or delete account otherwise you won't be able to Bind in below add device step.
11. in App click “+” or “Add Device”.
12. Enter your Network Name "My24ghz".  Also, Make sure you connect smartphone to the same "My24ghz" Network. In settings/Wifi on you phone.
13. Follow the prompts to connect app to doorbell. - Enter Password of Network. Click checkbox 2.4ghz Network only works. 
14. Press doorbell button for ten seconds or until resets.
15. Hold near doorbell to complete binding
    
     

I've had TMobile internet for 3 months.  My Blink cameras worked fine for 2 months and now they are not working correctly.  I did have Spectrum with no issues.  Can anyone help me resolve this.  Blink Support says it's a network issue.

@Saleeen  On the back of the modem there's a reset button you press with a small pin. 

@Saleeen the nokia5G21 is the original modem that tmobile put out.

I will try this, what do you mean by resetting the nokia5g21?

@Saleeen @bronkema i was having the same problem with blink module. I tried every suggestion that was given here and nothing worked. What i ended up doing was resetting the modem (nokia5G21). I'm sure they all have a reset button on the back. I re-did the whole setup process as if i had just received it. I reconnected to the app and set up a the 2.4ghz with wpa/wp2. I went through the steps for the blink sync module 2 and it connect on the first try. I hope this works. 🙏 

NO, The problem is TMobile Gateway has disabled close to 100 to 250 million home security systems and that is why you get no answer how to fix this because from what I've been experiencing for two months after getting robbed because T MOBILE DISABLED MINE AND ABOUT 260 Million PERFECTLY RUNNING HOME SECURITY SYSTEMS IN THE PROCESS OF THIS MONEY GRAB from HOME INTERNET USERS TRYING TO PULL A MONOPOLIZE ON ALL THE MAJOR INTERNET PROVIDERS WHO RUN THE GAME and endangered around 300 MLLION LIVES to crime IN THE PROCESS. They don't want let out of the bag THAT Tmobile REALLY DON'T CARE WHO OR WHAT ARE THE RESULTS AS LONG AS THEY MANIPULATE EVERYONE AND EVERYTHING IN THEIR PATH AT EVERYONE ELSES COST TO YOUR SECURITY, AND YOUR SAFETY. YOU AND ALL OTHER INTERNET CONGLOMERANTS  FINANCIALLY, LEGALLY, BECAUSE AS THEY CLAIM IN EVERY LAWSUIT THEY LOSE $32 MILLION, $175 MILLION, AND THIS MOST RECENT $500 MILLION. WHEN THEY LOSE THEY CLAIM "NO WRONG DOING" IN EVERY ONE THEY LOSE FOR "BRIECH" IS HOW YOU DON'T HEAR ABOUT COMPENSATION ANY WHERE AND ALLOWS TMOBILE TO GIVE YOU MAYBE TWO WEEKS TO CLAIM AND THEN DISQUALIFY THE VICTIMS BEFORE THEY EVER FIND OUT ABOUT TMOBILE BREACHES WITH NO SUSPECTS TO 300MILLION PEOPLE THEY SOLD YOUR INFORMATION TO (I MEAN HAPPENED TO HAVE A SECURITY BRIECH)  THINK! $500MILLION DOLLAR TAX LOSS WRITE OFF WITH (NO SUSPECTS) AND ONLY TMOBILE INVESTORS ARE INFORMED TO CLAIM ON THE WINFALL WITHIN A TIME PERIOD BEFORE THEY CLOSE THE WINDOW AND KEEP THE SLUSH GAINS ( I MEAN LAW SUIT LOSSES)  (THEY LOST BUT NO VICTIMS NEW ABOUT THE COMPENSTION ($25.00) TO VICTIMS THAT CAUGHT WIND AND FOGHT WITH TMOBILE LAWYERS TO GET THEIR $18.00 CHECK LESS TAXES AND FEES)    THIS IS WORSE, CRIME RATE IS AT AN ALL TIME HIGHEST THIS COUNTRY HAS EVER SEEN AND TMOBLI DISABLES 250 MILLION OF THEIR CUSTOMERS HOME SECURITY SYSTEMS ENDANGERING EVERY SINGLE CUSTOMER UNDER TMOBILE INTERNET NETWORKING SCHEME THEY ARE RUNNING. 

I've tried every suggestion here to connect my blink sync module 2. Created new 2.4GHz with WPA/WPA2. Reset the module. Still the same error message on blink app. I guess I'll keep resetting the module till it connects. 🤦‍♂️

As I recall. it was finicky and I needed to reset the sync module several times before it finally joined the network. Follow the instructions in the Blink app.  You need a paperclip for the reset button.  

If anyone gets this to work please let us know. Blink mini cameras without the sync module work excellent.
