Your internet plan provides 105 Mbps download speed. If by "bottleneck" you mean a router that will provide at least 105 Mbps LAN speeds, then pretty much any router from the last few years should do. You really need to provide more details. E.g. number of wired/wireless devices (and whether they're wireless AC, wireless N, etc), size of house/apartment you're trying to cover, use cases (e.g. gaming, streaming between devices, etc), your budget.
