Nokie Gateway Sudden Packet Loss

I'm having the same problem.  I've had a Gateway for about a year with no problems.  As of about 3 weeks ago, it's not working.  Internet is not available on the Gateway.  My devices can connect to it but with no internet connection...what good is that?  Phones are working fine, even the mobile hotspots work (which is what I've been using and with a generous upgrade to 100GB by tmobile, wow!).  I'm on my 2nd Gateway and waiting on a 3rd.  I've done the troubleshooting (factory resets on and off the phone with tech support) on both devices so far and nothing has changed.  I'm in a rural area and our options are limited as far as having a steady internet connection...and even if I wasn't in a rural area the prices are outrageous.  I've been with other providers and it usually boils down to "initially great service to gotcha, you've been tricked."  You have to wonder if all of the execs from all of the major carriers sit around laughing at these forums...I'm exhausted from dealing with people when I call who have no clue as to what I'm talking about.  But they kinda have you screwed.  If you want internet and mobile phone service, you have to deal with them, especially in my case.  I guess going back to what I had in 1980 is my only choice.  No internet or cell phone.  Just a landline and the postal service.
