I was going to suggest that, but let you troubleshoot first. I used one of the D-Link extenders, connected via a cat- 5e cable that went in there a decade ago, going to where my router used to sit. It worked great. I recently finally moved my gateway out of the basement where the wiring was, by dragging the cable over and fishing it up to my living room, which is dead centre to the whole house, and no walls in between, so I actually don't need the extender anymore.
Rogers talks about WIFI all over the home - if they actually had rewired their connections of 10 years ago plus and put them in the most optimum positions, we would have far less problems.
This is why you pay 150.00 for a Bell install, they are putting new wiring in and optimizing for location and use all over the house, then have integrated capability for one of the top Mesh systems out there.
Glad it worked out for you.
roblund Can you tell me how you set-up the extender to connect to the modem? I have a D-Link DAP-1530 extender and the instructions say to press the WPS button on the modem and the D-Link so they connect. Cannot find a WPS button on CODA-4582.
