Hello, I'm posting here after many failed attempts to get a satisfactory response from the live chat technicians, and the moderators here seem more helpful.
Hi @ceerokuro !
Welcome to the Community.
Although we as mods are not trained in Home Internet tech support, you can always ask some other Community members for help, through similar conversation threads.
If you do believe the modem is faulty though, did the technicians explain why they refused to proceed with a modem swap?
Also, when using only the Fido modem for Wi-Fi, you should be able to benefit from a high-speed connection.
Is there a specific reason why you're using a third party router as well?
