General discussion related to Cable Modems, DSL, Wireless, Fiber, Mobile Networks, Wireless ISPs, Satellite, or any other type of high-speed Internet connection, general issues and questions here. Review and discuss ISPs as well (AT&T / SBC, BellSouth, Bright House, CableOne, Charter, Comcast, Covad, Cox, Cablevision / Optimum Online, TMobile, Verizon FIOS, Shaw, Telus, Starlink, etc.)
The downstream speed seems good, residential broadband is usually download-oriented, and they usually discourage customers from running any server applications, hence the disparity.
I'd try the TCP Optimizer's "optimal" settings, what OS are you using ?
