does yr laptop freeze mid afternoon hornsby area?

if you live in the hornsby area of sydney and have had problems with yr laptop freezing mid afternoon while you're online i'ld love to know how you solved the problem

i'm tired of my wireless broadband modem ( virgin usb ) connection crashing if i try to use the web between 2-7 when i 'm working form home

it doesnt happen every afternoon but if it does happen it is mid afternoon which makes me suspect some kind of local intereference with the signal?

my other laptop (I'm accessing the web from an older slower laptop) is a sony vaio s series running windows and the frezzing oocurs mainly in Facebook but also when I'm using google chrome for research

what to do
