If you are on a low-data plan but require multiple devices (more than 3 or 4) to connect to your internet for multitasking or HD streaming, upgrade your current plan to a higher one. Here are some of the tried and tested methods to troubleshoot AT&T internet: 1. Physical obstructions around the router.High-data-consuming apps running in the background.Multitasking on multiple devices simultaneously.Too many devices connected to the same network.Sometimes, one or more reasons are collectively responsible for AT&T data being slow. To fix it, upgrade to a higher plan or convert Coax cables to ethernet cables. If the ping rate is between 100-150 ms or above 150 ms, you can observe latency and jitter, causing slow AT&T internet.So, contact your ISP for technical assistance. If the download speed is normal, but you notice the upload speed being so slow than normal, there could be some hardware issues.Restrict the data usage, remove unwanted devices, and check again. If the upload speed is normal, but the download speed is low, it could be because of bandwidth restriction, internet congestion, or excessive data usage on multiple devices. Your internet is slow if the upload and download speed is lower than the plan’s speed.Compare the results with your plan’s advertised speed to know if it’s actually slow. You can perform a bandwidth/speed test to check your current data speed. The 5 GHz signal doesn’t extend as far as a 2.4 GHz, but it has more options to bypass interference problems. When doing so, look for one that supports both 2.4 and 5 GHz Wi-Fi signals. If your router is older, it might be time to upgrade. If you have plaster walls, consider moving the router as close to the center of the home as possible. Either your walls are very thick and dense, or your router is old and unable to broadcast very far. If you step a room or two away from the router and find you’re quickly losing the signal, it’s time to consider the age of your router and its placement. Check for interference, consider changing channels, or upgrade to a router that supports 5 GHz (or even 6Ghz) if your current one doesn’t. For instance, if you can reach the edges of your home and still see a 60 dBm signal (or most of the bars), then any issues you’re having aren’t Wi-Fi-strength related. Once you know how strong your network is, you’ll have a better idea of what to do to improve it. You’ll see dBm measurements in the RSSI entry. Hold the option key and click on the Wi-Fi symbol. On Mac, you don’t need to download any program or app if you want to measure the connected network. Like on a Mac and iPhone, you’ll find dBm measurements listed under the RSSI entry. Just unzip and double-click the EXE file. The program is free, easy to use, and doesn’t require installation. In the past, we recommended NirSoft’s WifiInfoView to inspect Wi-Fi channels, and it also gets the nod for checking Wi-Fi strength.
