Two PCs in the organization I manage can no longer connect to any wi-fi(office, home or hotspot).
The users reported that the issue started on Thursday 16/06/2022. They were suddenly disconnected from the wi-fi they were connected to, and from tat time could no longer reconnect, or connect to any other wi-fi.
I have reset the wi-fi adapter, and attempted to update(using a LAN cable for internet connection) – but Microsoft reported that the driver is up to date.
However, after i uninstalled Sophos Intercept X Endpoint that was running on both PCs, they could connect to any wi-fi normally as before, but upon re-installation of the Endpoints, the issue came up again.
I formatted one the PCs and reloaded the Operating System. It could connect to wi-fi, but once I installed the Sophos Endpoint, it could no longer connect, - “Can’t connect to this network” is the message displayed after entering the wi-fi password.
I connected a USB wi-fi adapter(manufactured by Realtek) on one of the PCs, nd the PC could connect to wi-fi normally with it.
The PC model is HP 250 G2
OS is Windows 10 Pro
The wi-fi adapter model is QCWB335(written on the adapter card)
The wi-fi manufacturer is Qualcomm Atheros
*But the driver installed for it by Microsoft which had been working is Qualcomm-Atheros-QCA9565, as seen in Device Manager
I am suspecting that that there must have been an update from Sophos that is causing this abnormal behaviour, because all other systems in the organization are working fine right now.
I need help to fix this as soon as possible.
what version is the endpoint running? 2022.1.1.3 or something else?
OK, thanks for that, it is a recent version to be released which had updates to the NTP component so that sort of fits why it maybe a new issue.
It sounds like it's likely to be hardware/driver specific. The original post detailed the following.
Model HP 250 G2, Windows 10 Pro and the wi-fi adapter model is QCWB335. Another USB Wi-Fi adapter was fine.
Can you detail what make/model/OS and adapter details you have for any computers with this issue?
Also, you say "notebook continuosly reboot", is the computer bugchecking, i.e. BSOD? The original post was just about connecting to the Wi-Fi, nothing about the computer crashing.
I have same issue on two Dell Latitude 3570. They seem to have a wireless with a chipset Qualcomm (It's marked dell).
In one of them I have done a system restore to resolve the reboot issue.
Yes. same here all the effected WIFI drives are Qualcomm chipset.
Hi, Is there any progress on solving the problem? We only encountered it on dell vostro desktop computers.
Also such a problem with wi-fi, the problem is only with Qualcomm Atheros, there are no problems with Intel and Asus
As per my comment above (screenshots), can you confirm if disabling IPS alone helps or if you need to disable the whole Protect network traffic feature.
As suggested by Sophos Support, temporary workaround is to disable sophos network threat protection service through services.msc.
I am waiting news from the support after log analyzing.
Once NTP is disabled and the computer can connect, is it sufficient to disable IPS in policy, wait for that to appear in the registry as I mention above and then start the NTP service again? Maybe reboot? If you only need to disable IPS to get it to work that would be good to know.
