We have been working with our DSL modem vendor, Pace, to identify and resolve an issue where high network traffic is causing difficulties with customer Internet access. This issue has been 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 have coordinated with Pace to push out a remote firmware upgrade to all our deployed Pace modems by the end of the business day. This upgrade requires no action on your part. No downtime is anticipated and no modem reboot is required. However, if you begin experiencing any difficulties with a Pace 4111N modem you purchased from Spiral, call our office at (530) 478-9822 or (916) 252-1619 and press Ext. 1 for technical support.
EDIT: After further conversation with Pace we will push the upgrade on Monday, Jan. 27.
However, if you are currently experiencing slow/erratic Internet issues and are using a Pace 4111N modem you purchased from Spiral, you can manually install the patch before the vendor push with the following instructions. This is not necessary — it will simply allow you to install the fix early if you would prefer not to wait through the weekend.
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!
