Intermittent (each startup) Wi-Fi with an Edimax EW-7318USg

Question

Firstly, Wi-Fi works 100% of the time on my Ubuntu netbook, my Android phone and my Windows install (on the same computer/USB-wifi device), so I don't think this can be a router issue... It would be strange if it were a driver issue as it sometimes connects, but FYI the USB-wifi device is a Edimax EW-7318USg.

Second, if it does connect (during this session) then it connects first time, else it will not connect (no matter how long I try). Wi-Fi does connect about 20% of the time (restarting the computer about 5 times usually allows me to connect). Once it has connected it stays connected (until restarted).

Obviously it is hugely irritating! Any ideas how I can remedy this?

EDIT: As requested, the results of running sudo lshw -class Network:

Is this a known bug or should it be filed as one? (if so, which or against what?).

google didnt bring up any hits for that model - are you sure if it is correct? Please add to your question the results of sudo lshw -class Network — fossfreedom, May 27 '11 at 21:54
My mistake, I misread the S for an 8, it's actually an EW7318USg. Thanks! — hayd, May 29 '11 at 08:45
@fossfreedom I have corrected the device name in the question, and inserted the results of sudo lshw -class Network. Many thanks. — hayd, May 29 '11 at 08:57
This question should instead be filed as a bug report, and as such is off-topic, thanks! Instructions here. — Panther, Feb 27 '12 at 19:22

Find out if any log entries are helpful - I usually do:

touch $HOME/now

Record the time right now. Then, make the event happen (or, wait until the event happens, doing periodic touch $HOME/nows.

Then, after the event has happened, do find /var/log -cnewer $HOME/now to get a list of the log files that were changed between the most recent touch $HOME/now and the find command. Look at the last N lines of each.
