Do you have very slow Internet? There may be a very good reason. Here’s some suggestions…
If you ring your ISP’s Tech Support (all the numbers are here) ask them to perform a line test to see if there is a fault on the line. If everything is OK with the line ask them to do a flush/line refresh/port reset and this will usually bring the speed straight back after several minutes. It’s like a plumber flushing dirty pipes to remove any blockages.
I have posted all the Australian Tech Support numbers on my website if you need to call them, with some handy tips and tricks that should help make things easier too.
