Hi there, I upgraded a Dell Vostro 260 desktop PC (with a Dell DW1525 wireless card for network connectivity, using an Atheros AR9280 chip) from Fedora 22 to 23. IPv4 continued to work, but IPv6 packets seem to go into a black hole, even ping6 or ssh. I added ipv6.disable=1 to the grub configuration as a workaround, but I'd like to understand what's going on. I booted both the PC and a netbook (having an AR9281 wireless card, which also uses the ath9k kernel driver, connected to the same wireless router) from the same Fedora 23 Workstation live image: IPv6 works perfectly on the netbook, but not on the PC. Fedora 22 and 21 worked fine, too. I also tried to boot F23 on the PC with the 4.2.6 and 4.2.8 kernels from F22, but IPv6 doesn't work in this configuration, either. Any idea what might be wrong? I could attach the full output of lspci -vvnn if it's useful: 03:00.0 Network controller [0280]: Qualcomm Atheros AR928X Wireless Network Adapter (PCI-Express) [168c:002a] (rev 01) Subsystem: Qualcomm Atheros DW1525 802.11abgn WLAN PCIe Card [AR9280] [168c:0203] Thanks, Laurentiu -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
