@penalvch TP-Link Archer C5_V1.20_150428 is the firmware on the access point. Other 5 GHz devices are connecting fine.
I'm currently at work and we have an enterprise 802.11x setup with Cisco AIR-CAP3602I-N-K9 APs with the AIR-RM3000AC-Z-K9 AC modules. I am unsure what firmware revision is on the Cisco APs, they are centrally managed by WISM controllers. What is interesting at this point is that I can now see the networks advertised on the 5 GHz band, indicating that the scan for these networks is working. My android device is definitely connecting on 5 GHz correctly. The MacBook Pro 11,5 with the broadcom chipset only connects to the 2.4 GHz endpoints. ** Attachment added: "This contains dmesg output for 80211 entries and 5 GHz scan in Cisco enviornment" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509614/+attachment/4506158/+files/cisco-ap-environment.log ** Summary changed: - Wireless BCM43602 802.11ac 5 GHz not scanable on linux-firmware 1.1.49 - MacBook Pro 11,5 + Wireless BCM43602 802.11ac cannot connecto to 5 GHz networks - MacBook Pro 11,5 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1509614 Title: Wireless BCM43602 802.11ac cannot connecto to 5 GHz networks - MacBook Pro 11,5 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1509614/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
