Routing to a different segment

How can I make (PC 172.22.226.22/27) able to ping to (172.22.226.198/26 Switch) and (PC 172.22.226.197/26)

currently (PC 172.22.226.22/27) can only ping to 172.22.226.201 but not to 172.22.226.198

Network looks something like this:

(PC 172.22.226.22/27) —- (172.22.226.5/27 Switch) —– (172.22.226.1/27 Router 172.22.226.201/26) —– (172.22.226.198/26 Switch) —– (PC 172.22.226.197/26)
