Hi guys, I’m currently using Digi 300mbps plan for around 3-4 weeks now and ever since the first day, I experienced speed slowdown at usually at night to 200mbps(beside router) and 160mbps on my PC with wifi card(10 steps away from router) both on 5ghz wifi. The speed is good usually at day time and slow down at night. If I reboot the router, the speed will become fast again which my PC also get 300mbps full speed. But then if I don’t reboot the router, the slow speed continue to next day and following the day after. Also, sometimes this problem occur on afternoon as well and will slow down 1-2 hours after i reboot the router.
I’ve contacted Digi support and this is what they did.
1)Changed from WPA3 to WPA2.
2)Turn off IPV6 security.
3)Change a new router.
4)Switch from AX mode(wifi 6) to AC mode(wifi5).
4)Do setting this and that with the router.
And the problem still there. Despite all the slow speed im getting using WiFi, I got full speed even exceed (310mbps) using LAN cable on my PC even when the wifi speed is slow down.
I have no idea why and how… asked friend and people from facebook group, they say switching to a better router will fix the problem but I don’t want to spend another rm300-400 just to risk this.
Is anyone facing the same issue as mine? Or do anyone know how to fix this? Please help.
Router is ZYXEL EX3300-T0
