When you’re trying to troubleshoot your cable modem, your cable company will probably blame your computer. Many modems have a built into diagnostic page that lets you view what’s wrong with it.
DSL Reports created a master list of these pages. Usually, the address is <span><a href="http://ift.tt/1LniK1d; data-attr="http://ift.tt/1LniK1d; data-uid="inset3408" data-processed="true" id="inset3408" data-provider="default" class="">http://ift.tt/19QkNzh></span>. On that page, most companies include:
- Signal levels
- Uptime — how long your connection has been up
- Errors like DHCP fails or corrected/uncorrected blocks
- Reboot the modem remotely.
If you can read the page to the cable company’s support, that gives them key information to help solve your problem. It’s handy if you have an intermittent connection problem.
