Here are the best tips to fix no internet access on your wifi router.
To fix this problem, we will first start with understanding what exactly the problem is on the network. Is it your ISP or your router, or maybe the device settings have changed accidentally. Let us try our different 5 minutes fixes based on the exact problem. This step-by-step guide will 100% solve your issue of wifi connected but no internet.
1. Troubleshooting Router Problems
The router is one of the most crucial devices in a network. It directs internet packets based on the user request. The main job of a router is to receive the data packet, analyze them, and forward it to the respective end-points.
When your ISP is transmitting the data, the router acts as a checkpoint and forwards the data to different users and devices or routers. If the router has misconfigured settings, it won’t be able to transmit the data. Troubleshoot your router using these following steps if you are facing no internet issue.
The issues at the router end –
- Outdated hardware and firmware
- Router positioned in a low signal zone
- Snag or hitch with the internet cable that plugs-in the router.
How to Troubleshoot Router Settings –
- Restart your router and modem or turn it off for at least 30 seconds to 1 Minute.
- Check if your router is physically damaged, change the router in such cases.
- Make sure to update your router with the latest firmware.
- Check if the WAN cable connected properly, confirm it by checking the router lights.
This should fix your wifi connected no internet issue, if it doesn’t then you should check the next steps.
2. Router Lights
Router lights can help you understand why your wifi is showing connected but no internet. At first, when the router turned on, the wifi light should blink first and then the other two. The wifi light should be stable from the beginning.
While this is not the case with internet connectivity light, this light should be flickering at first and then be stable.
If any of these three lights turn red, the issue persists from your ISP end. In this case, you need to contact your ISP and resolve the changes.
In conclusion, this should solve the issue with troubleshooting the router and knowing if it is the cause for no internet access on your wifi.
