Earlier in September I went on a course to broaden my knowledge on networks and in particular Wi-Fi. I learnt a few interesting facts which I thought I would share with you.

I have many customers who have intermittent Wi-Fi problems, signal strength is weak or devices  (PC or phone) won’t connect. Sometimes this can be a problem with the device, for example the computer might need updating, or a malware infection is interfering, but more often than not there are other issues at play.

The 4 most common problems are:

  1. Interference or “Noise”. Wi-Fi works on radio frequencies and so do lots of others things in your home. Just like tuning in a radio you can get interference which makes it hard for the computer to receive the data coming from your Wi-Fi router. Examples could be microwave ovens, house alarm motion detectors and cordless phones.
  2. Next Doors Wi-Fi. This is another interference problem, a bit like Wi-Fi crossed wires. It is important not to be on the same channel as your neighbours.
  3. Built structures. If your home has a metal framework or thick concrete walls this can limit the ability of the Wi-Fi to penetrate through. Often the main house will have a good signal, but the extension over the garage has a weak signal because of the thickness of the external wall.
  4. Too many devices. Some routers especially the free ones your get from your ISP aren’t robust enough for technology rich families. Some routers can only support 8 or 9 devices on Wi-Fi. Tablets, Smart Phones, Kindles and TVs soon add up to exceed that limit.

There are several solutions which vary from turning up your Wi-Fi (using a signal booster), running cables or changing the frequency channel that your router is broadcasting on.  On modern routers, this can be done by just restarting the router. If you need any Wi-Fi advice please get in touch to book a consultation.
