For both ADSL and VDSL broadband, other electronic devices in your home, can produce electrical interference, including halogen desk lamps, electrical dimmer switches, stereo and PC speakers and fairy lights.
If you are experiencing broadband performance issues, try unplugging these and other electronic devices to see if this makes a difference to your internet speed.
Use the best quality wired (Ethernet) or wireless modem to connect your broadband to the internet.
A new device will usually connect faster than an older modem. It is recommended that you place your modem on a shelf or table, not the floor.
Aim to locate it as centrally as possible and place it away from sources of electrical interference.
Try not to obstruct the wireless signal between your router and device, for example, white ware, fish tanks or thick walls.
The age of your PC or laptop, your browser settings and virus protection can affect your broadband speed. For maximum performance it may also be necessary to update your wireless device software and drivers.
If you are using ADSL broadband, check that you have broadband filters, also known as ADSL line filters installed on your existing phone jack points that are connected to landlines, fax machines, security alarms or Sky Decoders.
