Wifi Tips for Better Connectivity
See if you can get closer to your at home router. Sometimes distance can be a huge factor in wireless integrity as some homes have structural interference that can hinder communication with the router and your devices.
By going to https://speedtest.net/ Go here to run a speed test to see exactly how fast your internet is for the device you're using. If you get anything similar to a result like- Ping: 100ms Download: 20Mbps Upload: 10Mbps then this indicates you may have a slow internet connection at home. You can further validate this by running the same speed test on your phone as phones in this day and age have the best wireless capabilities. If the phone has the same issue then it most definitely may be your Internet Provider who needs to take a look at the issue.
If you have an ethernet port on the laptop and an ethernet cable lying around it is almost certainly always better to directly connect your device to the router. This is because wired connections are rated much higher than wireless as well do not fall prey to interference issues. So you would get better speed and reliability. As well you can further validate using the speed test mentioned above after wiring in.
Sometimes the router you may be using is too old. If it was provided by your ISP the router should be decent and perform well enough but if you are using your personally owned older router you may want to upgrade. If it is anything older than 4yrs it will have an older wireless protocol that runs at a slower speed. Newer routers run 802.11ac/ad/ax which is a protocol that allows wireless to run much faster and will be compatible with newer hardware that can connect to it.
I do not recommend getting anything that is called a "repeater" or "extender" if youre trying to fix a dead zone in your home. These things typically make situations worse. A hotspot would be a good idea so long as it gets a decent cellular signal. That's about all I think I can provide for tips. Let me know if this was helpful to you.
