I just retested and no joy. I won't bother to post any new forensic information as it seems somewhat likely that this bug hasn't been worked on since the initial report. In my experience, when an actual wifi fix is made, a new firmware is made available to go along with any new driver(s). Since this hasn't happened, then I'm not sanguine that any work has actually been done. Unless I see some new evidence to the contrary, my feeling is that the Intel 7260 as used with linux is an orphaned product.
I did try to reopen the issue but was unable to do so. Perhaps if I were the originator of the bug I would be able to do so. No matter, out of sight, out of mind. I've hinted previously at Intel's willful neglect of the N7260 and here is yet more evidence. I don't see the point of marking a bug as resolved by a code fix when a code fix hasn't actually been implemented.My guess at this point is that as Intel's first 801.11ac radio the N7260 has so many problems that fixing them isn't worth the effort. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1913350 Title: Intel Wireless-AC 7260 (rev bb) wifi card crashes randomly Status in Linux: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: Intel Wireless-AC 7260 (rev bb) wifi card crashes randomly. Sometimes after 1h of using my laptop, and sometimes after resuming from sleep. It can't work again until I reboot my laptop. The most relevant error message is: sty 25 14:42:13 leetbook kernel: iwlwifi 0000:25:00.0: Failed to wake NIC for hcmd sty 25 14:42:13 leetbook kernel: iwlwifi 0000:25:00.0: Error sending STATISTICS_CMD: enqueue_hcmd failed: -5 I'm using Ubuntu 20.04 that was upgraded from 18.04 and earlier 16.04. I've searched for similar bugs, but it looks like my error message and card model is a bit different. The workaround script from bug 1673344 works to fix the wifi without rebooting. The card works fine in Windows 10 so it's not a hardware issue. This is not a stock card from HP EliteBook 8470w, I've replaced it to gain Wifi 802.11ac transfer speeds.
