3G kept disconnecting

My 3G (using a Huawei modem) had been stable at my new workplace
the last ten days but today, it's been disconnecting every 1-2 minutes.
Signal bar/strength today is 3 bar, used to be four bars.

If I leave a continuous ping (to gmail) running, it will last longer, say
every 10-30 mins.  What went wrong?  I'm not aware of any changes,
other than on 5th Jan 2014, there's a Java 7 Update 45 being updated
into my laptop but I did not reboot the laptop (always Hibernate) till
last weekend when the laptop blue-screened & I had to reboot it.

Does the Java update took effect only after a reboot?  I also noticed
that one Wifi service that I previously could detect at my workplace
is not detectable today despite that I right-click & select "Repair" on
my Wifi (not the 3G): is this related?

I could connect fine to my home Wifi though.  I'll try the 3G when I'm
back home tonite before I attempt a Windows XP "Restore Point".
Any other ideas?

In my experience, a restart is required only if you refuse to close any open browser[s] while the update is run.

Probably not.


The 3G adapter might be going bad.
I had one that exhibited similar symptoms, so I took it back to my provider, they tested it, charged me a small fee (about 10% of what the adapter cost me new) and gave me another one in exchange (newer model, since they didn't sell the one I had anymore)... it has worked fine since.

I would check for a driver update for the WiFi adapter.

The Huawei 3G modem works fine today at workplace while
the undetectable Wifi is detectable today.  I'll close this for
now & test the 3G modem with another laptop the next round
