Fiber throttled to 300mb by forced modem

From what i can tell after shelling out 500 bucks for a new modem and router system, and paying far too much every month for gigabyte fiber speeds, I've been forced to almost nothing speeds with pitiful range because I'm "not allowed to change the modem". If this is indeed true and i am not allowed to use the full speed that i clearly pay for, just because you want to charge equipment fee's for tech you don't own, i will be filing a (Edited per community guidelines) for damages and goods lost due to misleading and illegal business practices.

Your AT&T modem is not limiting you to 300 Mbps. Mine tests regularly at 999 or 1000. Note 1000 is the limit of the tests when using an external ONT.

If you are seeing 300 Mbps on Wi-Fi 99% chance it is your devices are not capable of Wi-Fi 6 (802.11ax) or your third-party router does not have a fast enough processor back-plane switch fabric to support 1 Gbps on it's WAN port.

What modem and router system did you purchase?

You can't replace the AT&T modem but you can use IP/Passthrough mode or try one of the many bypass methods floating around. A Bypass method will not work if your area's infrastructure has be upgraded to XGS-PON or if you have the BGW320 provisioned with it's internal ONT.

If you have a new BGW320 with the internal ONT activated and a SPF Optical transceiver you might even hit 1.2 Gbps on downstream devices when using the 5 Gbps LAN Ethernet port and a device that can fully utilize a 2.5 / 5 Gbps Ethernet adapter.

You must use AT&T's proprietary modem/router combo unit (Gateway). But you can combine it with your own chosen router.

Not illegal just because you don't like their business model.
