You're asking if the setup you have meets the requirements for high-speed data transfer. The cat5 standard supports up to 100Mb/s over twisted pair cables, which matches the capabilities of a phone jack. That seems to be your goal.
It seems the connection might be failing due to either the service provider's outage or a problem with your Wi-Fi link to the router or gateway.
If your devices are linking to the modem through Wi-Fi, the main problem is likely your Wi-Fi router (or the modem itself). Based on what I understand of your setup, you probably use an ADSL modem from your internet service provider that already includes Wi-Fi. Over time, these units can lose performance, especially if they're not updated regularly. The simplest fix would be to replace them with a dedicated Wi-Fi router connected directly to the modem using a standard Ethernet cable. It’s tough to find a ready-made modem today, so buying a Wi-Fi router is often more practical. This setup will give you a stronger signal and better reliability. ISP equipment tends to be of lower quality.
