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?
