A port error is when your modem and the DSLAM's communication is interrupted by a power failure or a link break. When you switch your router off, it causes a port error and we need to reset the port so that you are able to communicate with the DSLAM to connect to the internet. Too many port errors could either mean that you have an intermittnent connectivity issue or the port you are connected to is faulty and it needs to be replaced by a Telkom technician. If your equipment is faulty and causes an intermittent connection that will also make the port faulty and a Telkom technician will be able to identify what the cause was once a fault has been logged. They will also advise what you need to check and probably change your equipment before it does more damage to the port.
To resolve a port error from your end you may powercycle the router by unplugging and re-plugging the power cord. If this does not help kindly use the below steps to troublehsoot and get back to us with the results.
Intermittent connections are generally either related to a line fault or router problem. To test your line, try connecting with a different ISP account (or a different router) and see if the problem persists. Also, for your router, disconnect all devices and switch the WiFi off and then connect a single device to connect. Then try connecting devices one by one and see if one of the devices causes the problem, or if it only occurs when WiFi is brought back up.
For problems that could be related to network, I highly recommend using our Network Test App. This will show you if there is any high latency on your line, and where the latency occurs. If the latency is on the first hop (to your router) it is probably a local network problem. If the latency is to the second hop, then it could be Telkom exchange congestion. If the latency occurs at the end of the traceroute, then it could be load on the server you are trying to access. Whever latency appears to suddenly spike is an indication of where the problem is.
