Slow WIFI After Yum Update last night

HI All,

I was getting 13-15Mb's on my connection before running a Yum Update last night. When I use my PC this morning, speed tests are fluctuating between 2- 7Mb's

Anyone have any idea why? I had trouble with the Ath9k Drivers on Mint and Ubunut,but was great on Centos 6 until now.

My Device Atheros 5008, TP Link Wifi Card.

Welcome to the CentOS fora. Please see the recommended reading for new users linked in my signature.

Please provide more information about your system by running "./getinfo.sh" and showing us the output file.

All I can see with any certainty is that the ath9k driver is correct for your hardware, and that you have not rebooted to the latest kernel after updating. Try rebooting to 2.6.32-220.4.2.el6.

$ grep -i 168c /lib/modules/*/modules.alias | grep -i 0023
/lib/modules/2.6.32-131.17.1.el6.i686/modules.alias:alias pci:v0000168Cd00000023sv*sd*bc*sc*i* ath9k
/lib/modules/2.6.32-131.21.1.el6.i686/modules.alias:alias pci:v0000168Cd00000023sv*sd*bc*sc*i* ath9k
/lib/modules/2.6.32-220.2.1.el6.i686/modules.alias:alias pci:v0000168Cd00000023sv*sd*bc*sc*i* ath9k
/lib/modules/2.6.32-220.4.1.el6.i686/modules.alias:alias pci:v0000168Cd00000023sv*sd*bc*sc*i* ath9k
/lib/modules/2.6.32-220.4.2.el6.i686/modules.alias:alias pci:v0000168Cd00000023sv*sd*bc*sc*i* ath9k
/lib/modules/2.6.32-71.18.1.el6.i686/modules.alias:alias pci:v0000168Cd00000023sv*sd*bc*sc*i* ath9k

For some reason it seems you killed the "yum repolist all" part of the script, but there are some issues hiding there. You have mutually incompatible repos RPMforge and EPEL installed without yum-plugin-priorities, and the message "Repository geekery is listed more than once in the configuration" with that unknown repo would worry me.

It just boots automatically. How would I boot to a specific Kernel?

Thanks for your help.

Please do not quote the preceding post unless required for context. It just adds noise to the channel. If quoting then trim to the required subset.

The latest kernel should become the default on reboot unless the behavior has been changed by editing /boot/grub/grub.conf of /etc/sysconfig/kernel. You can pick any installed kernel at boot time by interrupting the boot process and choosing it from the GRUB menu.

Booted with both Kernels, no change. Still intermittent speeds on wifi.

Check for other things such as neighbor's Wifi that may be interfering. Perhaps try another channel. Try connecting to a different AP and see if the behavior changes.

Thanks, but I have been through all the basic troubleshooting. The Ath9k driver has huge problems with other Disto's and was one of the reasons I chose Centos. I believe this is the issue. If I go back to Win 7, I get consistent high speeds again.
