I believe Ft. Myers is considered Florida Panthers home territory. Do you get every Panthers game on FoxSports Florida? If so, that's why you don't have access to the Lightning games.
Same problem here, but never once has anything from comcast been able to provide an answer better than 'It must be FoxSports, call them'. maybe time to pull the comcast junk equipement and find another provider, customer service it at all all time low.
Tampa Bay Lightning games have aired in the Fort Myers area during past seasons. Someone decided to broadcast it this 2017-2018 season. Now how do we get these games back?
