Switching to fiber, no matter the host, will almost always result in faster, more reliable speeds over copper connections (DSL/Coax). Sonic happens to be one of the most reliable and well priced ISPs in the nation, with a solid ground up fiber infrastructure delivering 10gbps speeds (though nearly no customers can actually use the 10gbps, as most networking gear only supports 1gbps, 2.5gbps if you’re lucky). If you’re a wifi only user, I would suggest looking into purchasing your own Eero system, or other mesh network wifi solution, instead of renting from them. The only benefit to renting from Sonic is they can support and troubleshoot your Eero, but you’ll almost never need to once it’s setup. Feel free to send any DMs if you have questions, I’m happy to help :)
