ġ00 packets transmitted, 100 received, 0% packet loss, time 99154ms not sure why, maybe some hints what can be changed in the FW ? I've tried many things already. The latency gets higher as I am downloading things, but otherwise it is as low as it should be
Bcm4360 vs bcm43602 download#
I've got stable 50 Mbps download and 20 Mbps upload (my ISP allows 200/20 Max as per my contract) Ok, I am really tired of using a usb wifi dongle, so I was digging a bit deeper and here is what I've got.Ĭhanging ccode=X0 to 0 and regrev=15 to 0 in the firmware seems like improving things a little and makes the connection more usable: Might be a thermal issue?Īs mentioned, the controller is a BCM43602 - from 'lspci -nn':Ġ3:00.0 Network controller : Broadcom Limited BCM43602 802.11ac Wireless LAN SoC (rev 02)ĭetailed 'lspci -vvnn' output is attached. Turning wifi off for several minutes and then turning it back on usually works. Only 2.4GHz is present - see attached 'iw list' output.Īfter 10 - 20 min the wifi stops working, losing the connection altogether.

Have to be within about 10 feet of the AP to get any signal at 5 feet distance iwconfig shows The brcmfmac module is loaded correctly, but the resulting wifi has several issues: The late 2016 MBP has a Broadcom 43602 rev2 wireless controller.
