Check for applications running in the background
Many applications run in the background on your computer
and some of these will be quietly using your broadband
connection for tasks such as installing updates or
uploading data. Examples include BBC iPlayer download
version. Make sure that all unnecessary applications are
shut down to prevent this. If this makes a difference,
then add back each application until you identify which
one is affecting your download speed. Having large numbers
of browser windows or tabs open may also have an effect on
your download speeds - try running the speed test with all
other web pages closed, does this make a difference to
speed?
Make sure your anti-virus software is up to date
Having up to date and operational anti-virus software is
crucial as viruses, trojans and worms can use your
broadband connection which can make your speeds seem to
slow. Viruses and adware can also cause your computer to
slow considerably which can make your broadband seem slow.
Password protect your wireless network
If your router works wirelessly, password protect your
wireless network. Make sure that no one is hitching a free
ride on your connection and taking up bandwidth which will
reduce the speed you see, password protect and encrypt
your wireless network to keep unwanted bandwidth hogs
away. If you don't need to use your router's wireless
network, consider turning it off completely (using your
router's configuration interface).
Check your download allowance
Make sure your ISP hasn't capped your speed because you
exceeded the limits of your monthly usage allowance or
traffic management policy. Many ISPs now reduce your speed
rather than charging you for exceeding your allowance. You
should be emailed a warning if you exceed your usage
allowance, however if you've simply exceeded the traffic
management allowance (often in place at peak times) you
won't be informed, your speed will simply drop for a fixed
number of hours (or until the peak period ends). Your ISPs
website should give you details of any traffic management
policy in place and inform you of the effects of exceeding
your usage allowance.
Use microfilters
Make sure all other phones/faxes/digiboxes/etc in the
house are connected via a microfilter. Microfilters
prevent other devices connected to your telephone system
from interfering with your broadband signal. Every device
connected to the phone system should use a microfilter. If
you still have problems, unplug all devices and gradually
add each back until you identify which causes the problem.
If you're using free microfilters supplied by your ISP or
with your router, consider paying for more expensive
microfilters with good user reviews - it's possible one or
more of your filter is faulty or of poor quality.
