Hi there! Error code WEASEL normally indicates a network related error. This could include a general loss of network connectivity, packet loss, or WiFi interference and stability issues. https://help.bungie.net/hc/en-us/articles/360048717852-Error-Code-WEASEL If you have tried all of the steps provided by this article and the network troubleshooting guide, it is possible that you may be experiencing potential modem or router hardware issues. This could include RF noise or bleed, or your router has entered a faulty state due to bad firmware or incompatibility with your modem or ISP. Can you please perform a speedtest on a separate system that is on the same network as your platform and provide the statistics of that while the game is running and you are in an activity? If you are not able to do so, your ISP should be able to monitor your modem's connection and monitor any latency or speed related concerns that you may be having. I would also recommend speaking to them to see if they can perform any tests on your circuit to ensure that you are not bleeding signal from your modem due to dirty connectors or improperly terminated cables.
