Been searching for days with no answer but a lot of things to get a head start. I typed in a ton of commands from other forums and here's my results.
First off, let me state that this is ONLY effected when I try to connect to my network out of about 12. I have no other problems connecting to any other network or device. I've tried hotspots around town and they all worked. My neighbor said I could use his to figure mine out. The password type WPA/WPA2 is used on both networks. Only mine keeps disconnecting and reconnecting.
Here's some stuff that might help you:
The wireless device I am trying to connect to is a Verizon SCH-LC11 7b7d and the network name is the same with the word “secure” addd on. The password is stamped on the back of the device and it works on everything else, so I know it isn't that.
Toshiba Satellite A105
I added the file “ath5k.conf” in “/etc/modeprobe.d/” with the “options ath5k nohwcrypt=1”

That was for my network right before it disconnected again.
# For some Atheros 5K RF MACs, the madwifi driver loads buts fails to
# correctly initialize the hardware, leaving it in a state from
# which ath5k cannot recover. To prevent this condition, stop
# madwifi from loading by default. Use Jockey to select one driver
# or the other. (Ubuntu: #315056, #323830)
(Is madwifi important since it's not in synaptic and I've never heard of it???)
I have rebooted several times. I changed the channel manually using “sudo iwconfig wlan0 channel 2”
I have tried deleting and adding it manually in the edit connections on the dropdown menu.
I tried the following from another forum:
NOTE: THIS ONLY HAPPENS ON JUST MY DEVICE. ALL OTHER NETWORK ACTIVITY ON ANY NETWORK IS PERFECTLY NORMAL AND SANE AND STABLE. It just won't connect to the Verizon 4g box thingy they gave me where I can't go into it like a normal router and play with options and I'm too lazy to try to break into it. The “connected” LED blinks all the time, going from blue (good to go) and green (standby) My Android phone and my other Ubuntu 12.04 64 bit laptop with a Broadcom (that was hell getting to work) driver connect to it just fine every try, as does my neighbor who let me use his connection to post this connected to my little box just fine with no problems from his house with a desktop and an iPhone.
sudo ifconfig wlan0 down sudo rmmod -r ath5k sudo modprobe ath5k nohwcrypt=1 sudo ifconfig wlan0 up
The last command is pointless as the one before it makes the wifi come back on. I still did it anyways.
P.S. Every Ubuntuforums thread marked “solved” had no solutions, so if I didn't post it in here believe me I tried. I checked multiple websites and threads and all the solutions are pretty much the same, starting most recent and ghosting back to 2008/9. I moved the Verizon box to another room thinking it was way too close (almost touching laptop) and no results.
I have 5 days to fix this as I am visiting and it's 2.5 hours from home.
