  1. I have a linksys cable modem thats really old. Probably close to 8-10 yrs old. Would a new modem speed up my download/upload speeds?

    Likely to change performance on 0.001% after the time and effort.

    1. make sure you have the latest firmware in the modem and your router
    2. get the latest driver for your NIC & WiFi adaptor
    3. google for TCP Tweeks

    Well yes, because of the newer download speeds coming up. Mine was rated for 43 Mbps I managed to get 47 Mbps out of it. Best to reset the modem if it's giving you problems or you think it's way to old.

    What's your transmit power: 48.2 dBmV this is mine. You should be able to pull up the Cable Modem Status screen: Default is

    My thinking was that the hardware per se has little 'hard coded functionality' and the firmware changes would be sufficient.
    Even the big boys (ie Cisco) are entirely controlled by firmware.

    Some Cable Modems like the Surfboard by Motorola were very bad modems. If the OP can find firmware update the modem.
