Hiya guys n gals as a new member here this is my
First post so I apollogise if this topic has been covered
Before.
We are having real big problems with our web n walk
Stick. When it works its great however most of the time
It just sits there doing nothing. It will have a really good
Signal on either HSPA, 3G or HSDPA yet it won't
Download or upload anything its so annoying. I've tried
The stick on three different laptops but it works the same
On them all?
I have figured out that it really does not like internet
Explorer! We use google chrome yet even then it keeps
Coming up that the website cannot be displayed.
I've run virus scans on all three laptops which pick up
Nothing. All three laptops are running windows vista.
Can anyone help?
