I'm setting up a Home office in my unfinished basement for Stock Day Trading. I need to install a cable outlet in my basement but the Shaw technician said I need an Electrician to instal the Ethernet cable. I want to keep my computer upstairs which runs on the old motorola 5101 modem and I have a Dlink wireless router which has two WIFI connections. Can I install a new Shaw Cable Wifi modem and run both in my house? I would not mind leaving my old modem setup. If I do have to change the old modem out, Can you run two Modems in the house?
