I have multiple neighbors with 300 Mbps Spectrum service, and the modem+router box they got from Spectrum only offers about 60 Mbps over WiFi even to 5 GHz-capable devices in the same room. (And if you ARE using a Spectrum modem+router box, fyi it will probably have junk WiFi speeds. And if your permanent solution will involve a router of some kind placed behind the modem, of course your router will also need Gigabit Ethernet ports, both on its WAN port that would connect to the modem and on any LAN ports you wanted to use for your own devices - otherwise your router would become the bottleneck.

The reason is that a 100 Mb link only requires that 4 of the 8 wires in an Ethernet cable be properly terminated, whereas a Gigabit link requires that all 8 be properly terminated.Īnd fyi, if your modem is a true modem-only device rather than a combo modem+router, I hope you're only connecting directly to it as a test, AND that you have Windows Firewall enabled during the test. I've seen poorly made cables (especially ones that people cut and crimped themselves) that only negotiate at 100 Mb. If you've confirmed that the modem supports Gigabit, then try a different Ethernet cable. If on the other hand you purchased the modem yourself and it doesn't support Gigabit, then you'd have to buy another one or again ask Spectrum to give you one.

If it was provided by Spectrum it definitely should if they're providing you with 400 Mbps service, but if you simply upgraded to that speed by calling them and still have an older modem, then the modem itself might not support Gigabit, in which case you should ask Spectrum to upgrade it. If that looks good, check the specs of the modem online (look for its make and model) to confirm that it actually has Gigabit Ethernet ports. Make sure the negotiation setting (or speed and duplex setting) is set to Auto rather than forcing any particular speed and duplex. First open Device Manager and go to the Properties of your Ethernet adapter, then select the Advanced tab. The fact that your system is negotiating a 100 Mbps link with the modem rather than a Gigabit link is your issue.
