You can run your own ethernet cable. You're near the maximum length for an ethernet cable, which I read is 328 ft for cat5e and cat6 cable, so make sure you get good quality cable. You'll need an ethernet switch and/or a wifi access point in the shop. The other end of the ethernet cable plugs into one of the LAN ports on your existing Bell router. Should be easy as long as you don't run into complications pulling the cable through the conduit. If you do run into problems and an ethernet cable isn't possible then a point-to-point wifi bridge is an option. Cable is much better, however.
If you do run your own cable then you will need RF45 connectors and a crimping tool to finish the cable ends.
