tmobile home internet keeps disconnecting

Same issue here.  Was working  fine up until about 2 weeks ago.  Now the signal is down to 2 bars and weak and keeps disconnecting from the server constantly.  Can be working on something and then no internet connection.  T-Mobile Tech said it shows they are working on upgrades in the area and to give it a couple of weeks…..my T-Mobile phone is not having any issues….just the internet.  I have checked the signal outside all around my home and the signal shows to be -114 dBm  and down to no signal at all and constantly going up & down in strength.  One would think they would be able to tell you if they were having issues due to the Tornado which damaged an area in Sherwood, AR off Kiehl Ave as that seems to be the closest cell tower from what I can find out.
