WIFI speed incredibly slow, just fine on windows.

[indieisgoininsane]

Hello. Recently, and for the first time since Ive had MX for 2 years, my WiFi download speed has slowed incredibly down, while originally at 20Mbps, it fell to 500kbps max. The quick system info will be below, but I am using a Broadcom BCM4313 802.11bgn adapter, with the "brcmsmac", "brcmutil", and "e1000e" drivers enabled, and the "wl" and "b43" drivers blocked. I have unblocked the blocked drivers, but it didn't do anything. And, lovely enough, the WiFi works completely fine on windows, with my download speed being from 19-21Mbps. I am on a Dell Latitude E6420, working on the latest edition of MX, completely updated.

Here is the quick system info:

Sometimes with B/G/N cards the driver will default to N which in theory is the fastest protocol, but in practice is so susceptible to interference, which forces multiple resends by the router, that it ends up being the slowest. You can, however, force the WiFi card to use G by right clicking on the wireless icon in the panel --> select Edit Connections --> double click on your SSID -- use the selection box to the right of Band to switch from Automatic to B/G --> save and exit.

Device-2: Broadcom BCM4313 802.11bgn ...
... driver: bcma-pci-bridge ...
... chip-ID: 14e4:4727


In fact no such driver. That only indicates either there are conflicting drivers or none of them was loaded.

The correct driver is bcma:

Code: Select all

$ cat /lib/modules/$(uname -r)/modules.alias | grep -i 14e4 |grep -i 4727
alias pci:v000014E4d00004727sv*sd*bc*sc*i* bcma

So, using the "MX Network Assistant" unblock and load it, and block others to prevent conflicts.


P.S. Also try enabling brcmsmac, bcma, brcmutil together
(yes you did that before but without the bcma. brcmsmac depends on mac80211, bcma, brcmutil, cfg80211, rfkill, cordic )

As an alternative: Enable wl only, disable all others.

[indieisgoininsane]

Would bcma be under b43 drivers? Its not a listed driver in my network settings

[indieisgoininsane]

I decided to just disable all other drivers, except the wl driver, and now my speeds are definitely back up to normal, thank you guys
