Any Linux Distro will do for the test - preferably a lightweight one so that it responds better seeing as it will be working from the USB stick. If the fault disappears then you know it is a Windows issue only and if it is still there then maybe a hardware issue such as switch antenna connections. If you have a Live Linux Distro on a USB stick then you could try one of the affected laptops with that. However that seems unlikely and updated systems get around this.

I have read on some Linux forums that it can occur because: 'Quite often, the weak signal is a symptom of the antenna wire being connected to connection #1 on the card when the default driver is expecting to see the signal at connection #2'. It is weird that you only get the issue on some laptops. Unfortunately, there are no logs as the connection doesn't get as far as getting to authentication so no log files are created on the authentication server. The WiFi infrastructure is massive as it is spread about the whole campus, however, the number of people affected is low in comparison to the number of users probably around 1% (not including staff which devices are all bought in large quantities at once.

The drivers we have tried ones from Realtek's website as well as HP's website's and also trying to see if windows updates do anything (which was the first thing we thought of being as a cause). It is an educational establishment so students are able to take in personal devices, unfortunately, we have no control over what devices they take in. I'd look for logs if it goes to authenticate and fails might be best to look up the security logs of whatever tools your using, should helpt to narrow down the why. Also not sure whay your wireless infrastructure is like, you mentioned you have 4000 users - so sounds like a massive issue.

I've seen the wrong ones cause this issue so many times, even when everyone thinks they are the same - sometimes identical models have slight variations on the wireless cards, this can cause you to need to install slightly different drivers.

And where are you downloading the latest drivers from? You want to validate they are the right ones. You should also try and maintain your fleet to have the same version at all times. Firmware would be the first step i'd go through. Hey mate - you mentioned drivers but you didn't mention firmware. The laptops also can connect to networks that have WPA2-Personal encryption.ĭisabling and re-enabling the network adapter, in network settings in control panel, uninstalling the network adapter and reinstalling it in device manager, updating drivers, rolling back to previous versions of drivers, checking for any outstanding windows updates using an ethernet connection.Īny help on what to try would be extremely welcome. The connection doesn't get as far as the authentication server so there are no log files saved on it to say why it is not managing to connect.Ī USB wireless adapter on the laptops connects with no issue at all. However, we have had some laptops with exactly the same specs and hardware and OS versions that connects fine

It is mostly apparent on Windows 10 Update 1803 but also been experiencing it on windows 8.1. Seems to be Realtek Wireless adapters of various versions and driver versions. Here is the really strange thing, we probably have around 4000 users that use their laptops/phones etc on WiFi but around 1-2% cannot connect their laptops to the WiFi due to this issue, when you try to connect and during the connection process it disables the network adapter and brings it back online and then states it cannot connect to this network. Mainly HP laptops with Realtek wireless network adapters, try to connect to the company network (we have 2 one for setup of a software that helps connect to the main network and means that the user should have no issues connecting after a password change as it should auto update the password. This is one of the most bizarre issues I have come across and to date, I have found no workaround or fix.
