I'm with Orange Broadband plus & over the last few weeks its been very slow when doing certain things!!
Streaming vids i.e youtube is ok, but signing in & out of hotmail is soo slow & as is most other websites i browse!
I'm wondering if its my ISP or my browser as when i click on a Google find, i sometimes have to click it twice to get the page loading & the 'egg timer' next to the arrow disappears fast & the page loading bar just sticks & the 2 'tv's' in taskbar are off & on & often non active!
I've tried clearing clutter with ccleaner to no avail & am wondering as you can see if its my browser (latest firefox) or ISP.
I was with Orange until recently and had been with them since the old freeserve days. I left because of the same sort of problems that you are experiencing.
It got to the point where my "up to 8mg" connection was slower than dial up during peak periods, Orange have started using traffic shaping software and throttling of connections to limit their users access during peak periods.
If you go to click here you will find a forum filled with people with similar problems to your own.
The only answer for me was to change ISP. I am now with Zen and get a rock solid 6.9mg download and no latency problems 24/7. As with all things you get what you pay for!
I know & i'm paying more for the shite i'm getting!! I will change hopefully when my contract is up!, but up to recent its adequate for what i need & i get free Tech support!! I'm juts wondering if its something Orange users are getting at the moment & not an issue with my pc or congestion my pc may have that i can sort myself, i dunno!
