Concerned about WiFi Security?

October 20, 2017: Concord Light Broadband is aware of the reports of newly discovered vulnerabilities in WiFi routers. WiFi Routers supplied by Concord Light Broadband are from Calix. Calix has tested these devices  and determined that they are NOT vulnerable to the WPA-2 KRACK attack.

However many of our customers do use other WiFi Router products as well. We encourage those customers to research the device they are using and install any patches recommended by the manufacturer.  You can check your device vendor here:

What Differentiates Concord Light Broadband?

No other provider currently operating in Concord has a 100% fiber optic solution. This solution is technically superior in terms of speed and reliability. CMLP offers Internet service in a manner consistent with the values and approach used to deliver municipal electric service to Concord.

Community Commitment

Broadband from CMLP will be reliable, affordable and priced so as to provide a modest sustainable rate of return which adequately maintains the capital plant and protects Concord’s community interests. CMLP believes that this combination of technology and commitment will be attractive to many customers.

Your Online Privacy is Important

Many people have questions and concerns about privacy, especially with all the news about changes in federal regulations. We believe that you should expect your internet provider to respect your privacy.

Concord Light Broadband respects the privacy of our customers. We do not collect personal data and we do not share or sell any customer information. This policy has been in place since day one. Now more than ever, we see no need to change it.

Note that the fiber optic infrastructure has been installed in approximately 95% of the CMLP service area. Unfortunately, some locations do not have fiber available yet due to issues accessing conduit or lack of conduit in the street. CMLP is working to get the last 5% of our service area connected to the fiber optic network. In some cases, this will require a significant construction effort. This work will be scheduled to coincide with other CMLP construction projects in order to avoid duplication of effort and multiple cuts on the same street.
