Often data connection issues occur due to damaged or bent ethernet cables and can easily be replaced. If the same problem persists with the new cable, it is very likely that issues are with the local network configuration, one or more of the network connectivity devices - like adapters, switches, routers, and so on. Such faults will require a higher level of troubleshooting by a licensed Telecommunications Cable Provider such as Demand Power.
It really shouldn’t come as a surprise that old cables, particularly your backbone cable, can often cause network problems. The backbone cable connects your network to the internet, bringing in signals from your internet service provider to all users on your network. If your home of office network cabling was installed 5+ years ago, it may be struggling to meet current bandwidth standards. This can cause data bottlenecks and sluggishness, especially where there are many users of the network and heavy bandwidth drawing websites.
