I am not getting the data transfer rate of 300 Mbps that Spectrum says I’m supposed to get and they say it is because the modem. According to your website, the Surfboard SBG6580 cable modem has a maximum data transfer rate of up to 343 Mbps down. Saying up to 343 Mbps means anything above 0 to 343 Mbps! In some data transfer rate test tests in the past, I have gotten around 235-to around 258 Mbps down. Just a little while ago, it was only 153.1 Mbps down.
Another issue is the lack of Technical Support for the product by the company! It seems Support is getting worse generally for things. In the past I have been able to call and speak to a person. Can’t it be done now?
