🤓 WiFi First Aid 🚑 #

Before we start, note: 2.4GHz WiFi is limited to around 50Mbps.

If you are experiencing slow WiFi speeds, try these 4 steps:
1️⃣ Reboot your WiFi router and fibre box. Check all your cables are clicked-in.
2️⃣ Check your WiFi signal strength (WiFi icon on your laptop or phone)
3️⃣ Run a speed test while in the same room as your WiFi router: www.speedtest.co.za
4️⃣ If you are seeing max speeds around 20-60Mbps, change to a 5GHz WiFi channel.

How to switch to a 5GHz channel: The phone or laptop you are using needs to support 5GHz WiFi, and you need to select a WiFi network which has a 5GHz channel enabled. Some people name their WiFi networks to show the channel – they choose names like:  ‘mywifi5g’. Some people enable both 2.4GHz and 5GHz channels on a single network name. Most modern devices will prefer using 5GHz when close enough to the WiFi router.

If you still notice slow speeds, do a cabled speed test with a laptop to check that the fibre line is healthy. Here is a guide for testing your fibre line.

100Mbps Speed Limit #

When you see speed test results around 90Mbps, the problem is usually a router with 100Mbps Ethernet ports or a cable which is damaged or old. Check that the router has Gigabit ports and you are using a fairly new Ethernet cable(Cat5 or better). An Orange LAN light on the fibre box (ONT / CPE) usually indicates a 100Mbps connection.
