CSiCable The Better Way - Approved Modems

CSi Cable works to insure a network that will give you the best performance, reliability, and security. We evaluate cable modems for compatibility and overall performance. Due to technical concerns, changes to our network and discontinued support by the modem manufacturer, certain models that were previously allowed will no longer be suitable for our network, and will not be allowed to be added, as we will begin phasing out use of those older Doc 2 models.

All modems purchased elsewhere (if on the "approved list") need to be registered and checked ($10 fee) to insure they function properly on our network prior to installation of service. We will perform checkout and give you a "GO" or "NO GO" answer.  If it does not work it will be returned to you. We will not attempt to troubleshoot modem problems. We do not warrant modems purchased elsewhere.

Should your customer owned modem stop working in the future, it is your responsibility to purchase a replacement or rent a modem from CSi.  We caution against purchasing STOLEN or USED modems from other locations. Please contact our Customer Service office for details - BEFORE YOU BUY ELSEWHERE.

DO NOT BUY DOCSIS 2 models, as they will soon reach End-Of-Life. While they may work today for STANDARD Internet service, they will not function to be able to get the Faster speed options offered by CSi such as TURBO or EXTREME. Most Docsis 2 listed below will work for 2mb up to 30mb, we will not allow them to be added to the network.

If we discover problems with models as we do firmware upgrades and network enhancements, they will be moved to the non-approved list. CSi makes no representation as to how long into the future these models will function.

If your modem is not on the list above, the model may be one that is known to not work well on our network or it may be an older model that will soon reach "end of life" and will need to be retired. We will not allow new users to add modems not listed above. If your owned modem, even if on the list above, does not work on our network, it is your responsibility to either purchase a new modem or begin renting. We do not warrant or otherwise repair customer owned modems purchased elsewhere.

Non-Approved: Models that are incompatible with our network. Do not bring in to try to use.

below are User Guides for some of the older models reaching end-of-life & being phased out - don't buy these. These units will not be allowed to be added to network. Any models below rented from CSi will be replaced as needed. We will not upgrade firmware of any Models owned by customer unless model is listed in the "approved list" above.

If you want us to test & certify for use a model that is not listed, there is a $20 test fee. Approved modems from CSi Computers are less expensive than most non-approved models.

No Longer Approved to Add: Older Models previously allowed for use but are now End of Life. We will not add these models to our network. They may work today, but for how long? We will not add them to our network.
