Sometimes you have no choice. I'm on Bell Canada fibre and as far as I've been able to determine there is no way to connect to that fibre other than their modem/router.
Check if it has a bridge mode. That will bypass the routing function and make it operate as a basic modem. Then you can connect your own router to it. If it doesn't, you can still enable the DMZ function, turn off the WiFi and connect your own router, but it will slightly increase latency.
Are you on the new GigaHub? You can get around it, but you need to purchase a specific SPON ... Module? Adapter? I don't know the right term. You can plug the fiber right into that and then plug the SPON into a SPF(+?) port on your router or use a media adapter for RJ45.
There's a discord (yes, I know, sorry. Its the only place I know to discuss this) for doing this with Bell's equipment. Theres a FAQ there that will find the exact SPON you need based on your service level and where you are in the country. Send me a message if you're interested in the Discord link.
Long story short, its way bigger of a hassle than it should be, and fuck Bell. As soon as Tek Savvy can resell their fiber lines, I'm switching back.
I specifically did not opt.for bell becaue they literally changed their modem to disallow the removal of the component that your could have plugged into your own device.
Once I learned this, I vowed no bell. Also fuck Rogers. They can suck a fat dick too
Or, if can’t avoid it, use it but you cut the wifi and other crap and connect your own router on it.
I use the Turris Omnia since a good decade now, still supported, open source based, i can put some services on it (vpn, ssh, nas, speedtest, ...), put some traffic rules / ports redirection, firewall, dns, hostname/ip per mac address, pihole, wifi conf, etc...
If i switch to another ISP, I change the box and everything rework quickly...
Is it just me or do all these recent press releases and marketing posts from proton kind of bring their own trustworthiness into question? I'm a subscriber and happy with their service but not necessarily the recent developments.
