Apparent routing issues with AT&T fiber
I have had AT&T fiber for over a year. Over the past several months I began experiencing several slow connection times. For instance, opening something as simple as MS Outlook would hang with Outlook displaying... "connecting to server" for nearly 3 to 4 minutes. This has now manifested itself into numerous other issues. When I am on my home network I cannot stream content from ParamountPlus, and IHeartRadio does not connect at all when attempting access from an Android device (my wife also has experienced several apps that require her to disconnect from the wi-fi to transmit info through different apps). If we disconnect from my AT&T WI-FI network and use mobile data, or use other wi-fi networks that are not our own, everything connects immediately and has no issues. This is clearly some sort of routing delay over timeout issue.
I have attempted to talk to support, I have had a new router shipped to me and installed. I was told that the firmware needed updates and a replacement was necessary. The problem persists and I cannot seem to talk to a competent technician. Anyone have a solution?
