Posted: Thu Jan 11, 2018 12:54 am Post subject: Wireless slow only on Gentoo [SOLVED] |
|
|
My wireless Internet connection has been slow, but only on Gentoo. Both using Windows and an USB booted SystemRescueCd, the download speed is 2 MB/s as expected.
It seems to me that this is a recent problem, because I ran a speedtest.net test a couple of weeks back and at that time I also got 20 Mbps.
I followed the Gentoo guide for my QCA6174 wireless card (https://wiki.gentoo.org/wiki/Qualcomm_Atheros_QCA6174) but even after updating the firmware, speedtest.net keeps showing download speeds of around 13 Mbps.
Any hints are greatly appreciated!

You can post
Code: | $ dmesg | grep firmware | _________________ Questions are guaranteed in life; Answers aren't. |

Ensure that you have proper regulatory domain support. Else your card will use the "world" domain which means limited channel support and low transmit power. Do not use wireless extensions with wpa_supplicant (-Dwext), but cfg80211 (-Dnl80211).
In the kernel, you need
Code: | CONFIG_CFG80211_CRDA_SUPPORT=y
CFG80211_INTERNAL_REGDB=n |
Also net-wireless/crda must be installed (net-wireless/wpa_supplicant usually pulls this in as dependency).
Finally, after connecting, check whether your regulatory domain is correct now:
wpa_supplicant should receive this information from the access point and then use crda to set the regulatory domain. If not, set it manually through
Code: | # iw reg set <countrycode> |

My regulatory domain was set to "00". After I ran:
I now get full wireless speed again!
Thank you!!
edit: After some time, my wifi transfer speed got reduced again. I switched out the wifi card on my laptop for an intel 8265, which works perfectly. |
