I'm curious, do you use wifi to connect?
If, so, on when you open the icon at the right
of your computer (the one for finding out where
the wifi connections available are) there should
be a reading of how much they have there.
It should read like this:
Network name (SSID) Channel WPS SECURITY SIGNAL MAC ADDRESS
Your computer name 11G None WPS 100% 00:MM:GG:...
So, what you would need to look at is: channel G's, if you don't have above 6G's it's off and on with memory to fill that page
with the graphics or the signal percentage is low. Both these things can lower the page refreshing html loading.
So, I'm curious, if, you have wifi. I steel like the best of them the WIFI of unprotected libraries, companies and unsuspecting users (hehe). So, I've had the same problem with
low channel G's and low signal. If I manage to find a connection
to higher groups, it works like a charm. Not sure if that is your issue. But, it was mine.
Hope that helps, mon amie.
