![]() ![]() Connect the ISP device back up to where you had it before and again, connect with just a laptop and run the same ping test again. Now if you see no issues here, then your problem is your IW or something on your network. If you see problems here, then it is your ISP's issue and you need to call them, they will do the rest. It it is only for a few seconds, set your ping intervals to 200 ms instead of 1 second and let it run overnight. Connect a laptop to the ISP device and run ping tests to your ISP's primary DNS (this is typically at your first hop and the best place to start). The best method is to start with your ISP device (t1 router, dsl modem, cable modem, etc) and connect it right up to the DMARC (smart jack if it is a t1, bonding device if it is eoc) using a new, short patch cable. The best way to start is to remove as many variables as possible. The hard part about intermittent issues is determining where it is intermittent - you need the where before you can determine the why. This often results in a boot loop that leaves the modem unable to connect for hours or even days.I deal with this sort of troubleshooting on a daily basis. ![]() Once this value reaches 53 dBmV, the modem will automatically power cycle and retry the connection. Once your upstream power value increases past 48 dBmV, it means that your modem is having to work harder to output adequate upstream power. Contrary to what instinct might tell you, high upstream power values indicate low power levels. Upstream power levels should be between 38-48 dBmV.Īny power levels outside of the above ranges should be noted, particularly excessive upstream power values.Downstream power levels should be between -7 to +7 dBmV.So, chances are that these target values apply to you It is one of the most popular modems in the world, and its firmware is used in the majority of ISP-leased modem/router combos. However, the modem used for this example is the Arris Surfboard 8200. ![]() Ideal power levels can vary based on your router's DOCSIS specifications. Line techs address problems stemming from the main connection to the cable line outside your home. Line technicians are different than the home technicians that typically answer house calls. In fact, chances are that appointments are booked as far as a month out, and getting a line technician to make an appearance is particularly tricky. Home technician appointments almost never occur on the day you call in a complaint. Connection loss is a common intermittent occurrence, but what do you do when the problem becomes incessant and unmanageable? If your issues become persistent, it is possible that the root of the problem has nothing to do with your equipment or settings, but rather is due to a problem on the side of your Internet Service Provider (ISP) and may require a special line technician to intervene. But in those situations, how do you tell who's to blame? If It's Not You, It's ThemĪs remote work and smart home setups become more prevalent, our tolerance for connection failure is shrinking fast. It can make you feel completely crippled in your ability to work or communicate, control your home, or monitor your security system.
