Updated Known Issues List 29 October 2019 / IPS causes issues with wireless network adapters

The Known Issues List has been updated with a new IPS problem. We have received reports of issues with IPS causing connection problems with wireless network adapters. 

In some cases the wireless connection is broken all the time, in other installations we've seen intermittent connection issues. Connections with wired Ethernet are not affected.

To solve the issue you can simply switch off the IPS setting in Central:

As we are still trying to fully understand the issue, sending us SDU logs is much appreciated.

Update: We have found the root cause. While we are still interested in learning if you're affected, we do not need more SDU logs.

  • Hi Jacqueline,

     

    Assuming you are asking for where to switch off IPS in the settings shown in the screenshot before, here are the steps to get to the setting. 

    1. Log in to Sophos Central
    2. In the navigation panel on the left, click on "Endpoint Protection"
    3. In the navigation panel of the Endpoint Protection, click on "Policies" under "Configure"
    4. You should now see a list of policies you can apply to endpoints. The first type should be "Threat Protection". Click the "Base Policy - Threat Protection" policy
    5. Click on "Settings"
    6. Scroll down to the section "Runtime Protection". You should see a few lines that have a blue background. The first one is "Prevent malicious network traffic with packet inspection", under "Protect network traffic"

    See also the screenshots in attached document.

  • Hey Vincent, the latest fix list for the 2.5.2 endpoint release indicates the Network Protection module was updated -- is this a fix for this Wifi issue?  Referenced here:  downloads.sophos.com/.../sesc_core_rneng.html

  • Hi Bruce,

    Unfortunately that is not yet the case. We have found the root cause of the Wi-Fi issue, and are working on a fix, but it has not been released yet.

    This release has nothing new with regards to the components in the EAP. We will update the EAP soon, but i will announce this in the forum so you are aware of any changes beforehand. 

     

    Best regards,

    Vince
