Home Internet Signal Very Good to Weak

I am having this issue as well. But, mine might be a little different. Someone changed my account to the TMHI lite.  I had unlimited for over a year with no issues. TMobile did put me back on the unlimited but now I get poor signal. I was getting 4 bars. My internet has come to a crawl. Nothing is loading. 

I think our issues started when they rolled out the lite version. IMHO
