2 Accounts? - Time Warner Internet

This question is about "2 Accounts?", with Time Warner Cable internet and apps. When I bring up the list of available networks. I see mine listed 2 ways. One is the network name and the other is the same, but with "-5G" added. I can sign into each using the same password. Here's the strange part. When I run a speed test the first one shows around 40 Mbps for the download speed. The second one (5G) shows 154 Mbps! Anyone have this happening? Also, when I run the "what's my IP address" app I get the same IP for each.

2 Accounts??
