Spectrum recently upgraded our lines to a symmetric 750 Mbps down / 750 Mbps up. Is that too much for this router? I see that it’s rated for 600 Mbps throughput, but in speed tests I’m seeing more like 300 to 400 down / 150 to 200 up. A PC directly connected to the cable modem sees the full speed. Are there settings that I can change to make this router work optimally for these speeds? I understand that it won’t reach the full 750. The router seems like it may be causing other issues (high latency during uploads, WAN health check) at times with the new speeds.
600Mbps is the absolute peak throughput with optimal conditions. Depending on features turned on it can be less. If you want to take full advantage of the line a B One can do 1gbps and they aren’t terribly expensive.
