Your router is likely the bottleneck, not your internet plan. If your wired speeds are faster than your Wi-Fi, or performance drops in certain rooms, the issue is almost certainly your router hardware - and upgrading it will make a bigger difference than paying for a faster plan. A faster internet plan doesn't always translate to faster real-world Wi-Fi - your router may be limiting the speeds your devices receive.
