10. Change the RJ11 cable
- The RJ11 cable is the black/ grey cable which connects the modem to the filter. A faulty cable can result in a slow connection.
11. Disconnect any other equipment
- The overall bandwidth (speed) of your Unicom broadband supply will be divided by the number of computers/ devices connected to the router. The true speed of your broadband supply can only be obtained by testing with only one device connected to the router/modem.
- Disconnect/ switch of any additional devices such as laptops, iPads etc and retest.
12. Connect via an ethernet cable/ change the ethernet cable
- If you connect to the broadband wirelessly then there are a number of variables that can result in slower than expected broadband speed.
- These include interference from other electrical devices, the strength of the wireless signal and distance from the router. As such using any connection wirelessly commonly results in a reduction in the overall speed reaching the computer.
- Connecting via an ethernet cable will eliminate these variables and typically a hard wired connection will be considerably faster than wireless.
- If you already connect to the broadband supply with an ethernet cable then it may be worth replacing this, as cables can become faulty, resulting in a poor connection.
13. Check that the computer is not causing the slow browsing speeds
- There are a number of computer issues that can result in the PC operating at a slower rate than usual such as; antivirus software, firewalls, viruses, computer specification (e.g. RAM/ processor speed etc), browser software version, browser add-ons etc.
- To rule out any of these issues causing your PC to run slowly please ensure that your computer is virus free and try disabling any firewalls/ antivirus software. Updating your browser software and removing any additional add-ons can also improve the speed of your PCs browsing capability.
- If the browsing speed is still slow after completing the checks above try testing the connection with an alternate PC/laptopas this will rule out any limitations based on the hardware used.
14. Replace the router
- As with all electrical equipment, routers/ modems can deteriorate with time. An alternate router/modem should be used to confirm if the equipment previously used is the cause of the problem.
If you are still experiencing slow speeds after completing all the checks above then you may be experiencing a fault. In this instance please contact Unicom Customer Services on 0161 946 4444 to complete further diagnostics.
