Since about two months ago, my Lenovo Y50 laptop has been having issue with WiFi. It often cuts out and takes ages to connect, if it connects at all. It is also very slow when connected. Where I used to get speeds of around 65 mbps I now only get 10 (actually it fluctuates between 10 and 0)

Other than the slow speeds, I also get terrible latency issues. Pinging servers that I know are up (8.8.8.8 for example) yields a ping of over 400ms every time, if it doesn't time out.

I've tried the following:

  • Reinstall Windows
  • Update drivers
  • Try another network
  • Reset driver
  • Disable 802.11d

I've been breaking my head over this issue for over a month now and finally gave up. I replaced the hard drive in the laptop with an SSD when I bought it and lost the original drive, so I can't go back to the store and ask them to fix it.

Windows Event Viewer continuously shows errors about some WLAN service restarting (I'm not typing this from my laptop, I'll update the question with the actual message soon)

Wired internet works fine.

I have had the following OS's on the laptop on which I tried it, all had the issues:

  • Windows 10 Pro
  • Windows 10 Pro with anniversary update
  • Linux Mint 18 (cinnamon?)

I think the main issue is that the latency is very slow, so requests for downloads take a long time? (I don't know how downloading big files works, ignore me if that made no sense).

Thanks!

You should install a newer driver, your driver version 2023.34.430.8016 is a bit old. Because I can't see find the chip on the realtek site, I found working drivers on http://www.station-drivers.com/. Get the latest driver 2023.38.0701.2016 WHQL and look if it improves performance.

After contacting Lenovo about the issue, they agreed to an RMA.

The motherboard was replaced by Lenovo, after which the issue persisted. They then replaced the hard drive (failing to install Windows and putting FreeDOS on it instead) but the issue still persists. I'm sending it back another time before I start employing my secret weapon (EU consumer protection laws)

magicandre1981's answer about installing an alternative driver did drastically improve WiFi performance with the faulty hardware, so I'll leave that as accepted answer.

Here is the fix:

  1. Update your drivers
  2. Go to Control Panel then device manager, go to your Network Card e.g Realtek
  3. Right Click, Properties Go to Advanced then in wireless mode
  4. Select EEEE 802.11 B/G before it is in AUTO
  5. Go to Power Management and uncheck Allow computer to turn off this device.

Hope This Helps ;)
