HP ProBook 4530s - Unreliable wireless connectivity / slow speed

[Guest]

Wireless always worked fine when I had Windows 7. I'm using Kubuntu Trusty Tahr 14.04 LTS now as I am beginning a career in web development. Any help you can give to get this card working reliable is appreciated. I am open to replacing the module with one with better linux compatibility if necessary.

Ubuntu 14.04.2 LTS

We've seen this problem with Realtek wi-fi before. Try switching the module to use CPU-based encryption rather than encryption in the interface's hardware. Run the follwowing in a console:

echo "options rtl8192ce swinc=1" | sudo tee /etc/modprobe.d/rtl8192ce.conf >/dev/null

Now reboot. Any improvement?
