Public bug reported: When working on adhoc network creation feature we noticed that even though the N4 (mako) wifi driver claims it supports adhoc in reality there is a bug that prevents the creation of such network.
NM associates a set of capabilities to each wifi device it exposes. NM reports these capabilities based on the features the kernel drivers claim to support. The situation with mako represent a real world scenario where the kernel driver is not actually supporting everything it claims to support and now the problem is how can we blacklist features we detect not being functional. Ideally we would fix the driver, but this is not always possible if the drivers are coming from a 3rd party vendor or if they are proprietary. Therefore we must have means to do such blacklisting and IMO the correct place to do this would be straight on NetworkManager. This could be resolved by having a blacklist file under /etc/NetworkManager/ which would contain something like: [wlan0] NM_802_11_DEVICE_CAP_ADHOC=no Keys in this file would override any information NM is gathering from the device. ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1337764 Title: need a way to blacklist device capabilities To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1337764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
