BCM4331 (rev 02) should never be used with the wl driver-despite the fact that Linux Wireless's page on b43 () does recommend wl as an alternative for this chipset. No steps can be taken to troubleshoot its performance. ![]() It is impossible to optimize the wl driver. Unless these responses were made in haste, I must conclude: I believe you are using the incorrect driver. After making these changes, reboot the router. Also, be certain the router is not set to use N speeds only auto B, G and N is preferred. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. WPA2-AES is preferred not any WPA and WPA2 mixed mode and certainly not TKIP. Please consult the sticky: I believe you are using the incorrect driver.īit Rates:6 Mb/s 9 Mb/s 12 Mb/s 18 Mb/s 24 Mb/sĪuthentication Suites (1) : PSKPlease check the settings in the router. (.And for the record, I have the exact same setup as the example in 's bcm43xx page (), and they use the wl driver, so there.) Please don't recommend b43 as a solution-I've had huge troubles with b43 and I'm actually going to make a separate post about it. I'd like to optimize/troubleshoot the wl driver so it's as fast (or even nearly as fast) as my macOS partition. Why is wl on Ubuntu so comparatively slow? And I know, 80 Mbps at home isn't much to complain about, but I'm usually working at cafes where even the maximum potential on my macOS partition isn't fantastic. I don't know an equivalent of lspci for Mac terminal but, "About this Mac.More Info" reads:Ĭard Type: AirPort Extreme (0x14E4, 0圎F)įirmware Version: Broadcom BCM43xx 1.0 (7.21.190.18.1a3) Here are some test results from my house's 5G network, for example: At the same time of the day, in the same spot, at the same wifi location (be it my house or the library or multiple cafes), with nothing else running, wl is consistently ~half the speed as macOS. ![]() Wifi on my Ubuntu partition's wl driver is significantly slower than wifi on my macOS partition.
