Technologies
Modem/router technologies keep changing to meet the demands of modern devices. You know you have an old modem/router if you are still stuck on 802.11g circuitry. With this technology, it means you cannot connect efficiently if you are using 802.11n an above. Today, most of the latest routers/modems are operating on the 802.11ac circuitry but some have even gone a notch higher and are now on the Wi-Fi 6 circuitry or 802.11ax. If your modem is old then it means it will slow down your latest devices leading to frustrating lag.
Overheating issues
Most of the time that you experience slow internet connection there is often a corresponding heating problem. Heating problems is a signal that your modem is old and is need of change. You can solve this problem temporarily by getting a fan or moving your modem to an area that is well aerated. Modems/routers tend to be very similar to computers. They will come with processors and RAMs which produce lots of heat during operating. If your modem is constantly overheating then you can blast it first with compressed air to clear the dust. However, if the problem persists then it is time to get a new modem.Repairing a modem that has started having issues with its internal components can be frustrating and more expensive than just getting one.
Constant dropped connections
A good working modem should offer you uninterrupted internet access. You should be able to download large files and stream a live video to completion. However, if you notice that whenever you connect to the net gets disconnected then your modem could have outlived it’s purpose. But before you can make that decision to replace it, you may want to check your modem connections. Modems will connect to the internet through either VDSL, ADSL or DSL. Try removing the cables, inspect them for damages then put them back on. If the cables are the issue you can always purchase new ADSL filters or RJ11 telephone jack.
Check your modem LED lights
If you want to know the status of your modem check the LED lights. Each light represents something in regards to your modem operation. The position of the lights varies with some having it at the front and some at the rear. In your troubleshooting for your modem light put your focus on these lights.
- The power light: This shows you that your modem is powered on. If it is not then check your power connections from the socket to the cabling.
- Connection light: This is the light that shows you that your modem is well connected to the carrier or telephone exchange. This is the cable that brings in internet waves to your modem and then to your computer. If this light does no go on then know there is an issue with your internet supply. You may want to contact your ISP to find out first whether they have challenges with internet supply or billing issues.
- Internet light: Once all your connections are done right and there is internet then this light will turn on.
If you have any challenges with these lights then troubleshooting is specific. When none of these lights comes on (especially the power light) then it could mean your modem has completely broken down and you will need a new one.
Problems with DNS parameters
There moments when you will realize that the carrier is present and active but your devices are still not able to connect to the internet. The problem may not necessarily be with your ISP but with the telephone infrastructure. This will include your backbones and distribution lines. At times you maybe forced to change your DNS servers. If your modem has multiple Ethernet ports you can try to interchange your connections to see which works. If it works then it means the issue was with one of your LAN ports.

If you are operating on a modem/router combo then you know it is time for a new unit when you experience random reboots. Since modems operate like mini-computers they at times need to reboot so that they can restore some of your internal components. If you are experiencing challenges with your unit it is recommended that you first switch off the device then turn it on after 10 to 20 minutes or so. However, if the unit is itself constantly rebooting then the issue could be an internal one. Modem hardware problems are complicated to solve and repairs could be counterproductive. Instead make that step to purchase a new modem.
