When trying to connect to the router, the Wi-Fi adapter turns off and turns on again

Good afternoon, I encountered this problem a few days ago. When I try to connect to the router MikroTik, it knocks out the Wi-Fi adapter and it turns on again. I have a laptop firm Acer Aspire V15 black edition, previously normally connected and worked from this router.

The thing is that at home to my router of the usual company connects normally. I connect to MikroTik from my phone and tablet, no problems, but the laptop lately does not want to. Checked all the settings of the router, like everything is correct and my laptop is not listed in the black list. Help, I think already somewhere maybe my laptop has blocked access to this router.

Good afternoon. I’ve heard of a similar problem several times before and even encountered it myself. When connecting to new, unconfigured routers, I also had the Wi-Fi module (adapter on the PC) completely disconnected and disappeared from the system. Then it turned on and continued to work. But after building a Wi-Fi network on these routers (usually by changing the Wi-Fi name and password), the same computer would connect and work without problems.

Unfortunately, I don’t know any specific solution. And I’m not sure that there is one.

In your case, I would first of all do a network reset on the laptop (we have instructions, but I don’t know what Windows is on your Acer). Rebooted the router, that’s a must. It’s also a good idea to do a full reset on that MikroTik and set it up again. Set a different wireless network name. But I understand that you don’t have that option since the router is not yours.

Even if your laptop was locked in the MikroTik settings, it would simply not connect. But the Wi-Fi module would not disconnect when you try to connect to a Wi-Fi network. This is some kind of conflict, a bug.

What else you can do: disable WPS on the router, change the Wi-Fi network mode to “802.11n only” (after that you may have problems connecting older devices), check the network security settings on the router (put WPA2-PSK with AES encryption). You can also change the channel and channel width of the Wi-Fi network, but I don’t think that’s the problem.

In Device Manager, you can open the properties of the Wi-Fi adapter. There will be an “Advanced” tab with some settings on the left and options on the right. I can’t give specific instructions, as these settings are usually different and it’s not quite clear what to change. But you can try to change some of the settings by trial-and-error method, in case it works. Just remember what you change, so that you can change it all back later.
