Wi-Fi Router Connectivity Issues

I've been facing ongoing Wi-Fi connectivity problems with my router for the past few days. The issue includes frequent connection drops, devices failing to connect to the network, and extremely slow internet speeds even when I’m in close proximity to the router. I’ve tried restarting the router multiple times, but the problem persists. I’ve also checked for firmware updates, but everything seems to be up to date.

I've noticed that the issue seems to be more frequent during peak hours, but sometimes it happens at random times throughout the day. I'm not sure if it’s a hardware issue, a signal interference problem, or something else.

My router is a Tenda, and I'm using an https://10001admin.ph/tenda-router-login/ connection. I’ve tried moving the router to a different location to reduce interference, but that hasn't helped much.

If anyone has encountered similar issues or has suggestions on troubleshooting steps, settings adjustments, or even recommendations for a new router if needed, I’d really appreciate the help. Thanks in advance for any advice you can offer!
