Arris SB6190 not supporting 400 Mbps
We have an Arris SB6190 modem. A few months ago we tried to upgrade our Spectrum Internet service from 200 Mbps to 400 Mbps. According to Spectrum's website, this model supports the 400 Mbps speed. However, after we upgraded the service, we failed to get much more than 200 Mbps. We ran the speed tests from a computer that was directly connected to the modem via an Ethernet cord.
We spoke to a Spectrum technician, who ran a few tests and didn't see any problems. Since we couldn't get it to work, we reverted back to the 200 Mbps tier.
We would still like to get 400 Mbps if possible. Does anyone have any suggestions?
