The Most Common Wi-Fi Problems and How to Fix Them

In recent years, we have all become so reliant on Wi-Fi and a stable internet connection that even the smallest problem can impact our day.

We continue to see the growth of more appliances becoming connected to the internet; from fridges to printers, Wi-Fi connection is no longer only needed for smartphones and laptops.

Working from home has become increasingly more desirable, so having a secure Wi-Fi network that delivers fast and consistent connection has never been more essential.

As Wi-Fi installation experts operating around London and Essex, our team at JL Audio Visual can help provide a range of connectivity solutions, ensuring your home has the perfect Wi-Fi system setup.

Here, we delve into the most common Wi-Fi problems, the reasons behind these issues and how you can go about solving them.

A Slow Connection

Is there anything more annoying than a buffering video or an email that just doesn’t want to be sent?

Many of us will occasionally experience annoyingly slow Wi-Fi. This can be for a number of reasons and will require various fixes.

Router Location

One of the most common reasons behind a slow connection can be the position of the router and your location in relation to it. If you are too far away, connection can become slower and more unreliable.

The Fix:

Just getting a little closer to the router can often help speed up your connection. If this isn’t possible, it might be worth investing in a second router or signal booster to extend your network and reduce the likelihood of a slower connection.

If slow connection is a persistent problem, the issue could be due to interference from other appliances. Move your router to a higher position, away from other appliances to help combat this.

Lack of Bandwidth

Network bandwidth is essentially the capacity at which data can be transmitted. If multiple people are on multiple devices using the internet, there may not be sufficient bandwidth to cover all of them, meaning that connection becomes slow and is prone to lagging.

The Fix:

To fix this, try to disconnect some of the devices that aren’t active to free up some bandwidth.

If bandwidth is persistently slow and many people need internet access at the same time, you may need to consider opting for speedier internet that is capable of supporting all your needs at once.

Already previously mentioned, interference can be another cause behind slow connection. Routers can often end up competing for airwaves with other devices in your house.

The Fix:

Make sure there are no devices in close proximity to your router. You can also switch off any devices that don’t need to be on constantly.

If interference is not coming from devices within your household and is instead caused by a crowded frequency channel that many other nearby homes also use, you can select a less crowded frequency. Most modern routers will automatically choose the least crowded option when they are rebooted.

One Device Refuses to Connect

Another fairly common Wi-Fi issue that can cause irritation is when one particular device won’t connect to the internet. This can be especially annoying when your connection is perfect on all of your other devices!

The Fix:

Often this will just be a momentary issue, and the trusty trick of switching your router off and on again can help you out. Unplug your router and then plug it back in after 30 seconds to see if the momentary glitch has been fixed.

You can also delete your current network that is saved on your device and reconnect it after a moment has passed.

Rebooting the device itself can also be a potential fix.

No Internet Connection

Perhaps the worst Wi-Fi issue of all – when there is no internet connection! This can happen at random points or may be a more frequent problem that you run into often, but what is causing it?

Issues With The Router

A faulty router or modem can be the reason behind a complete drop in internet connection. Older routers may be outdated and simply not have the hardware or updates that will allow for the best internet connection. Periodic lapses in Wi-Fi could be down to glitches with a router that’s on its way out.

The Fix:

You may need to replace your router if this is the case. Wi-Fi speed and solutions are getting more advanced every year, so ensuring you have a capable router will be something to look out for.

Sometimes a glitchy router may be random and will not necessarily warrant replacement. You can once again try to reboot the router by unplugging and plugging it back in to see if this will solve your issue.

Service Outage

When your internet is down, it could be a more widespread problem than one occurring just within your household. Service outages that disrupt internet connection on a large scale can often be the issue causing your lack of Wi-Fi.

The Fix:

Unfortunately, as the problem is not on your end, there is little you can do to fix this. You can contact your service provider to let them know you have been affected, but beyond this, it will be a case of waiting for them to solve the issue.

Forgotten Wi-Fi Password

Sometimes, to regain Wi-Fi connection you just need to re-enter your password, but this is obviously not possible when you cannot remember it!

The Fix:

If, after a hunt for any scraps of paper with the password written on it, you cannot find anything, you will need to reset your router. To default your router to factory settings, use a paperclip or something similar to press the reset pinhole switch located on the back of your router.
