Laptop keeps disconnecting from WiFi

Laptop keeps disconnecting from WiFi. Definitely not a router issue as three other computers in the house are not experiencing this.

After a few minutes of connectivity the WiFi is no longer connected to laptop. When trying to 're connect sometimes the WiFi signal is no longer there, turning off the network search and on again several times and it appears again. Even when visibly it takes several tries of connecting the network to actually provide internet. It will say connecting then the network will disappear and the internet on the laptop will turn itself off, then on again and the signal is gone again.

Please help.

Hi @lolav

Does it do this if the laptop is positioned as close as possible to the router?

If not then there may be a problem with the antenna connection to the WLAN module in the laptop.

Here’s a link to the service manual for the laptop.

Scroll to p.53 to view the necessary pre-requisite steps and then the procedure to remove the WLAN module. This will allow you to check the antenna connections to the module to see if they are connected securely.

Try installing this free program. It is handy as it will give information regarding the signal strength of the WiFi as received by your laptop which may help in narrowing down the problem if it is not the antennas.

Yes the laptop is next to the router.

I'll give the antennae connection next.
