Pace Modem Update

A note for DSL/Fusion customers who purchased Pace 4111N modems from us prior to Feb. 2014:

In February 2014, we worked with our DSL modem vendor, Pace, to identify and resolve an issue where high network traffic was causing difficulties with customer Internet access.  This issue was tracked to a vulnerability in the modem firmware, leading to attacks where a large volume of spoofed traffic is sent to Pace modems in order to contribute to a denial of service attack against a third party.

We coordinated with Pace to push out a remote firmware upgrade to all our deployed Pace modems.  In most cases, this upgrade requires no action on your part.  However, if you are currently experiencing slow/erratic Internet issues and are using a Pace 4111N modem you purchased from Spiral, in some cases the patch may need to be manually applied.

(The patch on this page ONLY addresses the Denial of Service exploit.  It is NOT a full firmware update.)

If you bring your Pace 4111N modem in to our office, we can identify whether the patch was installed, and update the modem if necessary.  There is no charge for this.

You can also install the patch by following these instructions.  This is not usually necessary — please only do so if you have confirmed with Spiral technical support that your modem was not automatically upgraded.  If you have any questions about this, please call our office at (530) 478-9822 or (916) 252-1619 and press Ext. 1 for technical support.

1) Sit down at a computer that is using the Pace 4111N modem to get through to the Internet.

2) Download the patch file at this link: http://spiral.com/pacehotfix* If you right-click that link and choose “Save As…”/”Download Linked File As…”/”Save File To…” you can choose where on your computer to save it.  If you simply click that link it should go to your normal Downloads folder.

3) Go to this address: http://192.168.1.254/upgrade

4) Click “Upgrade.”

5) Click “Choose File”, and select the file named “pace-ntpd-hotfix.install.pkgstream” that you downloaded in Step 1.

6) Click “Upgrade.”  Wait for approximately 5 minutes while the modem installs the patch and reboots.

7) When the power light goes back to solid green and your DSL/Internet lights come back on, you are ready to get back on the Internet!
