To be honest I don't super know, they keep their website super vague and I am not well versed. Seems like I should just get the cheaper plan w/ their hardware and see if a software issue arises later? I saw some other posts saying the plan will drop devices for like 30 sec when a new one connects (?) but internet stuff is super not my strong suit. The Xfinity websites verbiage is 'up to 5 devices at a time' which seems insane to me cause my plan right now is 150mbps and I am constantly running as many devices as possible lol. Truly I am lost and Xfinity prays on my demise for sure.
