If you noticed certain unusual network behaviors, such as frequent connection dropouts, please check whether there were any suspicious records under Network Security. However, if your experience with Deco has no obvious connection with the mentioned issues, please start a new post with more details so that our engineer can address the matter promptly.
For users who had a similar issue but the attacking/blocking records are not included, please comment between with the Deco model number/firmware versions and a screenshot of the attacking/blocking record.
I have seen more issues since installing the firmware listed for problems with Intrusion Prevention.
Prior I really only saw problems whilst using a product called Emby but now I have been unable to access network drives on a Windows 7 PC from a Windows 11 PC. When I disable Intrusion Prevention I can then again access those network drives.
