|Hi James, presume you have a desktop pc.|
a) increasing the memory in your pc to maximum.
use the memory as stated in its manual
old memory is cheap on ebay
this will benefit all operations, not just the internet.
b) presume you have a wireless dongle in your usb port
a usb2 card will greatly increase usb1 port speed by around 40 times
a internal 6 port usb2 card (4 ext + 2 int) is around £5-6 here in the UK
This would be of benefit to any usb device you have
do not use a unpowered (or never a) usb hub
c) if your pc is close to the router, it would be better to use a direct connection
this will be faster (maybe twice usb2) than wifi
it will remove the overhead of running wifi from the pc.
check the router how to direct connect as it may be by network cable not usb
The above is not expensive, and should give very acceptable results.
you might run into a problem with something like skype as processor speed is required in conjunction with the upload speed of your internet connection for transmitted speech.
Please advise back on what you decide.
As a matter of interest, where are you located? I am in Hammersmith, West London.
Good Luck - Keep us posted.
