Intermittent connectivity is when you experience temporary lapses in your internet connection. In order to try and fix this, let’s check the below:
Firstly, we want to identify what devices are showing intermittency. Are all devices affected, or just a select few? We will also need to know if they are phones, tablets, or laptops.
Next, we want to identify how we connect to the internet – via Wi-Fi or Ethernet?
Most customers connect through Wi-Fi as it is more convenient than having a cable connection obstructing the property.
Although Wi-Fi has the advantage of convenience it has the disadvantage of reliability.
It is possible to reach great speeds in one room and not be able to connect at all in another room.
In regard to the Wi-Fi frequencies – 2.4GHz and 5GHz we need to keep in mind that although 5GHz in principle is faster it is much more difficult for the signal to pass through walls and also it's subject to more interference whereas 2.4GHz will provide speeds up to 450Mbps-600Mbps while still having a much easier time going through walls and combating interference.
In most cases moving the router to another place (away from electrical devices and larger metal objects) will noticeably increase the signal strength in some places of your home.
If it is intermittent on a wired connection this should definitely be investigated.
It would also be a good idea to keep in mind if all services are intermittent or if only select sites are causing issues.
Next, we can try with a wire to the modem, bypassing the router just to see if it itself might be causing issues.
Remember to look at the status lights on the modem to see if there is anything out of the ordinary, for example, the
