MIke Thank you for the observations. I did test the connection, since I am using cellular, I found several phone numbers to test against, and all of them provide good inbound audio but my outbound audio is just all corrupted.
I do not think that the DHCP assignment caused the problem, but I am trying to figure out if something else was changed on the network at the same time. i.e. different routing. I know that normally ip addresses are not geo based, but it was always of note that in the past any search or application that took me to a map would always take me to a map of the area I live in, now since I am one HughesNet, I see that I am now taken to sites that are no where near where I am, and I figured that it was probably where the gateway to the uplink to the satellites was located. I know that they have several of them, so I thought that might be the issue. I need to get on a wired internet connection and put the uCell on it and make sure I do not have something going on with the outbound side of the device. Inbound audio is so good, and it was working so well prior to the failure that I am left wondering.
