Maybe your like

Have you ever been annoyed at your internet connection that becomes so slow right when you need it? Well, you are not alone. I have faced a similar issue with my home network, where I struggled to watch my favorite online shows due to frequent buffering.

Finally fed up, I took the matter into my own hands and tried to understand the underlying causes of the poor speed of my home Wi-Fi.

In my case, I had several devices around the house connected to the network, and that caused it to slow down.

To solve the problem, I disconnected the devices that weren’t in immediate use and kept only the ones I actually needed on the network.

I also restarted the router to clear caches and found that the internet speed had improved, resulting in uninterrupted video streaming. I could go back to enjoy my favorite shows.

If you are someone like me looking to understand and solve Wi-Fi connectivity issues, then you’ve come to the right place.

This article looks into the grass-root problems of poor network connectivity and provides practical guidance to the readers on troubleshooting such issues.

To fix your Slow AT&T Internet, first, try rebooting your router and disconnecting extra devices. You can also try using an ethernet connection, scanning your PC for malware, relocating your router, updating your system drivers, disabling VPN services, and using a Wi-Fi extender.

Reasons for slow AT&T internet:

Some of the well-known reasons for slow AT&T internet include router issues, running background apps, using devices with low-performance, or it could also be due to choosing an Internet plan that is not fast enough to support the daily tasks.

Here are some of the reasons that put a dent in the speed of AT&T Internet.

Bandwidth Restriction

AT&T can reduce the bandwidth deliberately due to the following reasons.

If you exceed the bandwidth limit subscribed to in the plan, then the service provider can limit your bandwidth by reducing the internet speed. For example, if you had opted for a 10Mbps, and if your usage has exceeded the data limit, then AT & T can reduce the allotted bandwidth resulting in sluggish internet.

AT&T can also place restrictions due to network congestion during peak hours of the day. This might sound unfair, but the service providers resort to such practices to keep everyone connected and unstrain their network.

Too Many Devices Connected

One of the most common causes for poor connectivity is that too many devices are connected to the same Wi-Fi network.

For example, if a laptop and a mobile device are connected to a 4 Mbps network, then the bandwidth will be equally distributed across the devices. In this scenario, the laptop and mobile will have 2 Mbps each. This causes a significant reduction in Wi-Fi performance.

I highly recommend the reader connect and use one device at a time to experience good internet connectivity, especially while performing tasks that need lots of data.

Multitasking

I personally experimented by performing various tasks in my home network and observed that multitasking considerably increases network congestion, thereby reducing the performance of the internet.

I used my laptop to perform many tasks where one tab was tasked with YouTube (not playing it) and another tab for downloading a large file from my email; simultaneously, I used my handset for making video calls.

As it turns out, my video call was pixelated as it was deprived of data, but by disconnecting the laptop and all its tasks from the network, I could completely eliminate the pixelation from my video call.

Faulty Router

If you face intermittent disconnection on the internet, it could be due to a faulty router. I recommend connecting a spare router to check if connection issues persist.

If replacing the existing router with a new one solves the network problem, then one can understand that a router malfunction caused the issue.

If you’re facing frequent router troubles and questions like “Does the netgear nighthawk work with AT&T?” Or “Does Google Nest WiFi Work AT&T?” pop into your head, then the answer is, yes they do.

Surrounding Interferences

The most overlooked factor in addressing slow internet speeds is the presence of obstacles and external interferences.

From my observations, Wi-Fi signals can easily be dissipated or weakened in the presence of wireless devices or other similar devices operating in the microwave frequency range such as an oven, cordless phone, and other radio devices like a walkie-talkie, etc.

I was also astonished to find that a Wi-Fi signal from next-door neighbors can also impact and reduce the strength of the wireless network at my home.

AT&T Internet Outage

ISP Internet outage is beyond anyone’s control, and one can only wait until the internet disruption is addressed from the service provider’s end.

Some of the causes that result in internet outages include the upgradation of equipment and other maintenance activities at AT&T’s end, network congestion, disruption of optic fiber cables due to digging and road works, and natural disasters that could damage the network infrastructure.

How to fix AT&T slow internet:

If your motto is Do-it-Yourself and you like to solve problems independently, here are some of the proven methods to improve the speed of the Wi-Fi connection at home.

Restart Your Router

The first and foremost thing that needs to be done is hard-booting the router, which involves manually switching off the router and turning it back on again.

The logic behind this method is that it clears all the short-term memory in the device (also called power-cycle), especially the temporary IP addresses provided by the service provider.

On rebooting, the router resets the network adapter and begins fresh transmission of data packets received from the ISP, thereby offering better bandwidth for the user.

As a matter of fact, most users and even computer technicians suggest this as a remedy or as a first step in troubleshooting bandwidth and speed-related issues on the internet.

Disconnect Other Connected Devices

From my findings, the internet speed can be drastically improved if one could limit the number of devices that use the home Wi-Fi network.

If you live as a family or a group, ensure that there is sufficient bandwidth considering the data usage by each person in the family.

I have experienced sluggish Wi-Fi at my home when both my parents and siblings are engaged in online activities, but on the other hand, my home network is really fast when used in the wee hours where fewer people are online, in other words, less the devices connected faster the internet connection.

Use an Ethernet Connection

Wireless networks come with more packet losses in comparison to the ethernet cable.

I could notice the difference when I switched to ethernet connection as there was less interference and more stability, which resulted in a better internet speed.

Moreover, I could watch my favorite sports live without any lags and buffers.

For those who perform bulky tasks such as file transfer, high definition video, etc., the use of a wired connection is recommended because of the advantages mentioned above.

If ever your ethernet connection is slower than Wi-Fi, then you may have damaged cables or outdated drivers.

Scan PC for Malware

Computer devices infected with viruses and malware can eat your bandwidth by running unwanted apps in the background without the user being aware of it.

So It is recommended to scan and protect the PC with antivirus software.

Change Your Router Location

Bandwidth issues related to external barriers can be fixed by changing the location of the Wi-Fi router and placing it closer to your work area or in open locations.

In addition, ensure that obstacles like walls and appliances like ovens do not interfere with the Wi-Fi signal.

Additionally, you should also look out for the best mesh routers for AT&T Fiber or Uverse, depending on which one you have as mesh routers, and drastically improve your internet’s connectivity throughout the house.

Update Your System

It is no secret that newer devices come with updated drivers that are faster in processing data and more efficient in tapping into high-speed internet.

One of the ways of fixing slow Wi-Fi connectivity is by using updated network drivers on the PC.

Using outdated drivers can result in frequent hanging of the PC, and the user misses out on minor bug fixes that are addressed in the updated version.

Reset Your Router

Resetting the router can help clear all the customized settings so that the user can start afresh in setting up the connectivity.

I found resetting the router helpful in fixing issues related to its firmware that could not be resolved by restarting.

Internet issues related to router firmware can be fixed by resetting it.

Disable VPN Services

VPN makes use of proxy servers and utilizes an encryption process to shield the user’s data related to connectivity, privacy, and accessibility.

However, this encryption process and routing of data through proxy servers consume more internet that can dent the performance of the internet.

By disabling VPN services, the user can free up data resulting in higher internet speeds. This solution is also a fix for slow upload speeds.

Use a Wi-Fi Extender

One of the ways to improve Wi-Fi connectivity is to use an extender. The Wi-Fi extender acts as an amplifier; it picks the existing Wi-Fi signal and amplifies it to bolster connectivity in areas where Wi-Fi signal strength is weaker.

Contact Support

If none of the above methods work, you can reach out to the AT&T customer support team and log a complaint or seek technical assistance in restoring the internet speed.

AT&T will then look for issues at their end or send a technical team to check if there are any problems at the user’s end.

I’d also suggest looking up AT&T’s current internet plans to make sure you’re on a updated plan in case you’ve been using AT&T for a few years.

Final Thoughts

The guidelines, as mentioned above, are tried and tested methods that can be used whenever you are faced with frustrating Wi-Fi connectivity at home.

Moreover, the resolution steps are effortless, and one does not require the working knowledge of computers, networks, and internet topology to address slow internet connection.

However, I would also like to advise against cyberattacks and hackers who can intrude into your network by stealing your information.

If AT&T suspects any malicious activities, they can restrict data or block certain ports to protect the user causing slow internet speeds over a long period.

I suggest you install the AT&T mobile app to monitor and optimize home internet and Wi-Fi without any hassles.

One thing to keep in mind while resetting your router is that it will erase all your settings and return it to its original state, and you will have to set it up again.

So rest your router only if you absolutely have to, and do remember to note your settings down before you do it.
