Just a few updates which may be of use to anyone else having the same issues...
1). As this issue persists without a truly good solution, it may be a good idea to simply replace the wifi card with, say, an Atheros one which works better. You can find them relatively cheaply on ebay. 2). One of the major issues that I was having was that my main Wifi would crash internally, then whenever I tried to plug in a USB Wifi adapter they wouldn't work either, leaving me literally without any method of getting (wireless) internet. I assumed these two issues were connected, however, further research has led me to believe otherwise. I tried entirely removing the internal wifi card to see if that would make a difference on the USB wifi cards, yet still neither of mine worked. Further looking revealed one or two strange oddities... phy#1 Interface wlx000f6001cb1f ifindex 3 wdev 0x100000001 addr 00:0f:60:01:cb:1f type managed txpower 20.00 dBm The interface is WAY out of convention. As explained here (https://superuser.com/questions/1086632/wlan1-showing-as-weird- characters#1086705), interface names are limited to 16 bytes. My theory is that when network-manager tries to connect with this interface, it breaks that limit. The solution suggested in that thread works, append net.ifnames=0 to the kernel parameters in grub and suddenly all of my USB wifi adapters work fantastically. I have a feeling this itself may warrant a separate bug report, I'll do some looking and see if anyone else is having the same issue/if someone's already reported it. TL;DR: If your USB wifi doesn't work and you get weird/long interface names from "iw dev", use "net.ifnames=0" to fix the interface name and take back your wifi. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1684213 Title: Intel Wireless 7260 often crashes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1684213/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
