Posted: Sat Mar 21, 2015 7:25 pm Post subject: rtl8192cu Slow Speed |
|
|
I did a recent install of Gentoo. I'm using an ASUSTek Computer, Inc. USB-N13 802.11n Network Adapter (rev. B1) which uses the Realtek RTL8192CU driver (installed as a module in gentoo-sources-3.18.7). I'm connected to a Netgear R6300v2 flashed with DD-WRT (build 25697) at a 2.4ghz frequency (there's also a 5ghz band, but my adapter can't see it). The problem is that I'm finding that I'm downloading at a very slow speed (I'm downloading a file right now at about 14k/s and Steam is downloading a game at 211k/s). Running an Ookla speedtest measures 0.52mbps download, 2.77mbps upload, and a ping of 96ms. I'm connected to the same network on my iPad and ran the same Ookla speedtest with much improved results (11.51mbps download, 3.43mbps upload, ping of 60ms).
These are the entries in dmesg related to my adapter:
dmesg | grep wlp0s29u1u3: | [ 6.804872] rtl8192cu 6-1.3:1.0 wlp0s29u1u3: renamed from wlan0

I'm wondering if the last 3 entries are telling to the problem (that the power is being limited). Also, here's my iwconfig:
iwconfig wlp0s29u1u3: | wlp0s29u1u3 IEEE 802.11bgn ESSID:"{my ssid}"

Any ideas what could be slowing it down? |

yeah , i have on adapter that also uses rtl8192cu module.
Try it with this one : https://github.com/pvaret/rtl8192cu-fixes : it completly makes the difference in terms of stability and speed ! |

That's the module I had been using, actually, prior to my re-install. I started using it because it fixed an issue where a power saving feature turned off the device after 30 seconds of inactivity. I didn't use it by default this time because the kernel I'm using now has an option to disable automatic power saving (figured I'd give it a try). THAT problem hasn't been happening, so I preferred to stick with the kernel driver, but I'll give this one a go and let you know how it works. Thanks for the suggestion! |

Hmm... I'm having a problem building the module. It all goes well until I run the build/install command:
dkms install 8192cu/1.9: | Kernel preparation unnecessary for this kernel. Skipping...
Building module:
make -C /lib/modules/3.18.7-gentoo/biuld M=/var/lib/dkms/8192cu1.9/build clean
make: Entering directory '/usr/src/linux-3.18.7-gentoo'
CLEAN /var/lib/dkms/8192cu/1.9/build/Module.symvers
make: Leaving directory '/usr/src/linux-3.18.7-gentoo
{ make KERNELRELEASE=3.18.7-gentoo -C /lib/modules/3.18.7-gentoo/build M=/var/lib/dkms/8192cu/1.9/build; } >> /var/lib/dkms/8192cu/1.9/build/make.log 2>&1
Error! Build of 8192cu.ko failed for: 3.18.7-gentoo (x86_64)
Consult the make.log in the build directory
/var/lib/dkms/8192cu/1.9/build for more information. |
So I go to make.log, expecting to see a build error, or at least something to point out what went wrong, but I don't find the contents to be so obvious:
cat /var/lib/dkms/8192cu/1.9/build/make.log: | DKMS make.log for 8192cu-1.9 for kernel 3.18.7-gentoo (x86_64)

LD /var/lib/dkms/8192cu/1.9/build/built-in.o
Building modules, stage 2.
MODPOST 0 modules
make: Leaving directory '/usr/src/linux-3.18.7-gentoo |
As a side note, I typed all this in by hand, so if something looks odd it may be a typo. |

can you try doing it without dkms ?
can you check if /usr/src/linux points to your currenct configured kernel ( not a clean kernel , like when after doing make mrproper ) ? |

Kernel is linked fine:
ls -l /usr/src/linux: | lrwxrwxrwx 1 root root 19 Mar 7 08:59 /usr/src/linux -> linux-3.18.7-gentoo |
As for the build if I do it manually I get several warnings, but no errors and (to me) it looks as though it builds okay:
make: | make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/3.18.7-gentoo/build M=/home/alienjon/rtl8192cu-fixes modules

I know that dbus names the devices based on certain parameters, so I don't know if this is odd to begin with an 'enp' when other wifi devices seem to start with a 'wlp'. Also, I'm not sure why systemd-udev is being used, as I don't use systemd... These may not be anything important, but I figured it was worth mentioning.
In any event, I have an /etc/init.d/net.enp0s29u1u3 linked to /etc/init.d/net.lo. Starting it returns the following:
etc/init.d/net.enp0s29u1u3 start: | * Bringing up interface enp0s29u1u3

honestly, neither do i.
I remember one time, i had a very "light" kernel, and was missing some wireless usb modules that caused the usb wireless to not work.
I dunno if that is the problem, but can give a few hints:
* check if the required kernel modules are compiled and available, ( test a system rescue cd for example or another distro, try to compile that module and see if it works. if it does, take notice of the modules used. )
* check if using wext use flag, rtl8192cu doesnt need it but 8192cu does
Also , there seems to be some other 8192cu fixes versions available on github, but i think they are all based on the same.
Other than missing some wireless kernel modules, i never had much problem with using 8192cu module. ( my wireless adapter is a tp-link ) |

I'll try to check the loaded modules in my livecd when I have a moment. I am having an unrelated-to-my-wifi issue with my wireless xbox controller that, previously, was fixed by enabling a certain USB specific option. Didn't fix it this time. Might be related, but not really confident that it is. I double checked my /etc/conf.d/net file and noticed that I never actually added an entry for this device. I think it defaults to dhcp and wext, but specifying it didn't make a difference in the output. |
