I have an Ideapad 530s-14IKB I bought about a month and a half ago. Since day one I couldn't keep the wifi connection on for more than 10-15 minutes.
It was the same as described on these forums so many times: troubleshooter would easily fix it ("Default gateway not available") but you had to run it every single time, every 10 minutes or so.
I tried every single software fix you could think of or find online. Power management, drivers management, messing about with obscure adapter options, disabling bluetooth, etc.
I finally replaced Realtek 8822BE wifi card with another card (I won't put the model name here because I'm not sure if it's advertasing). I haven't had a single issue since.
I'm so upset and dissapointed that such an expensive notebook is shipped with such a garbage component. It is maddening to realize that you have to change computer parts, at your own expense, on such an expensive machine in order to get something as basic as wireless network working. Especially given that there are
alredy already so many reports of the component not working.
I hope this helps to the next person who will search for this problem.

Welcome to the Community Forums.
Can you try this dirver version instead.
Realtek Wireless Driver for Windows 10 (64-bit) - ThinkPad E480, E580
Do a ping test again and if the same issue, change Bandwidth setting under Advanced driver properties of the device manager from 80Mhz_40Mhz_20Mhz to 40Mhz_20Mhz.
I hope this helps answer your query.
Update us how it goes.

You can try the suggested steps using the original WLAN card. This would isolate the issue if it is really a hardware issue.
Hardware issue as such would be covered by the warranty so the option is open for tech support to explore since you have tried another wlan card that works fine.

I have been habing the same problem on my Lenovo Flex 14. I bought a cheap USB NIC and ultimately replaced the realtek 8822be card with the INTEL 8265 card. so far so good on the Intel card.

I've had this exact same issue for months and it's been driving me crazy. WiFi will stay connected but nearly all network access is lost. Sometimes it resolves on its own and other times I have to disable and then re-enable the WiFi adapter in the Control Panel.
Thinking it was something to do with my wireless AP (I have a lot of devices connected to it) I went as far as adding a new AP but the problem remained.
I think I finally found a solution. I found 8822BE drivers on the Realtek website last night and installed them. They were kind of hidden - I had to change a couple characters in the URL of another driver to match '8822BE'. My WiFi has been rock solid ever since.
Getting the drivers is a bit of a pain. You have to provide your email address and then they send you a download link. The link expires after several minutes so don't waste any time.
I didn't run the executable in the zip file. I instead installed them manually (i.e. Update Driver in Device Manager). The executable may work fine - I just didn't try it.

Well scratch what I said above. The issue returned shortly after posting. I ordered an Intel Wireless-Ac 9260 mini PCI-E card from Amazon to replace the current WiFi card.

Zero issues. So no one can convince me it was an OS, driver, power management, etc. issue.
I can’t recall where I bought it though.
