About 6 weeks ago we had our ISP (Spectrum) come out and troubleshoot intermittent loss of internet service. They replaced the cable running out to the road, and also said our cable modem needed to be updated, so they gave us a new one.
I use an Orbi mesh wifi router with my main PC. Steam/EA/Origin downloads with the old cable modem were reliably in the 22-28Mbps speed range. Ever since we got the new modem (technicolor tc8717t), they are pinned at right around 8Mbps, max.
I thought there may be some setting on the new modem that is throttling bandwidth to the router, but I can't seem to access it via the modem IP address (192.168.0.1). I called Spectrum and they basically said they couldn't help and couldn't see the setting on the cable modem (?!).
Oddly enough, running web-based speed tests show wifi download speeds in the 60-70Mbps range. But I have downloaded numerous games at different times of day from different services and never get about 8 or so Mbps.
