Weird unstable WIFI problem

Question

I'm using a TP-Link Archer V5 at home with both 2.4ghz and 5ghz available, and I have a Lenovo Ideapad 3 Gaming that runs on Windows 11.

If I connect to the 5ghz WIFI at home from my laptop, the connection often drops shortly after, and only gets stable after multiple tries. If I connect to the 2.4ghz WIFI instead, the connection would be stable at the first try, but then, it has constant lag spikes while playing games like DOTA or CSGO, like, a lag spike each second and it happens almost every time I use this WIFI.

This doesn't happen to another devices such as my phone or my brother's laptop, and at my workplace, as both 5ghz and 2.4ghz WIFIs at my workplace are fine. I've tried resetting my network, my router but it keeps happening.

Answer 1

I've tried all the steps above but unfortunately the problem still persists.

Answer 2

Hi. I'm David, and I'm happy to help you.

How far is your computer from this router?

Is there a mirror or metal furniture between your laptop and the router?

See if, when resetting the network, you did as per the instructions below.

If you haven't done it this way, I suggest trying.

1. Press "Windows + I" and select "Network & Internet > Advanced network settings";
2. Select "Network Reset";
3. Select "Reset Now", and at the confirmation screen, select "Yes";

Note: The PC will need to be restarted.

4. Now open Start and type cmd;
5. Right-click on "Command Prompt" in the result list and select "Run as administrator";
6. At the Command Prompt, type the following commands one at a time and press Enter:

netsh int ip reset

netsh winsock reset

ipconfig /release

ipconfig /renew

ipconfig /flushdns

7. Restart your PC and see if the issue is resolved.

Feel free to ask back any questions.
