Some players are currently unable to form Fireteams with other players connected to the same router or home network.  In recent weeks, we have identified a potential cause for this issue that was introduced by a previous Destiny Update. Internal teams are actively investigating ways in which to address this issue in hopes of implementing a solution in a future Destiny Update. We would like to thank all players who have posted reports to the #Help forum concerning this issue, as it has greatly aided in our investigations.[/quote] You can find current updates and information in the thread Marionberry, Canary, and [url=https://www.bungie.net/en/Forums/Post/210716770?sort=0&page=0]Local Network Fireteam Issues[/url]. Make sure your home network is properly configured by following instructions in the[url=https://www.bungie.net/en/Help/Troubleshoot?oid=13612] 'Allowing Destiny Connections' KB article[/url].

Additionally, below I have listed two possible solutions that may be able to get those Guardians back on the field! [b]Solution One:[/b] -Restart both games at the same time. - Be sure to only select your characters and do nothing else. - As soon as it loads, try joining together. This is a commonly used method, but usually doesn't have much success. [b]Solution Two:[/b] - Leave one console connected via Wi-Fi. - Connect the other via Ethernet cable. - Try joining together. Sorry to hear any inconvenience this may cause. Hope this helps!
