D-Link router device
Hey, guys I recently bought a D-LINK DIR-825 AC1200 router. It's been around six months now, and I'm experiencing slow internet speeds—about two weeks ago my download was only 15 Mbps while upload stayed at 53 Mbps. The speed was good when I checked the LAN connection, but resetting the router didn't fix it. I also tried switching between 2.4 GHz and 5 GHz channels, using multiple devices, and even moving closer to the router, but nothing changed. My ISP says everything is fine on their end. About a week ago a technician changed a setting, and my speed was normal, but yesterday the router reset again. I'm wondering what settings I should adjust to get full performance.
I won’t spend time going through all these images. Please revise your post and delete the pictures—they’re overwhelming and could be a risk if someone tries to breach your network.
What did you attempt with Ethernet? Have you checked for firmware updates? I once used a DLink router where the software was very poor; I had to flash it to DDWRT temporarily. When speeds seem slow, do you try restarting the router? Does the device feel warm? I've seen that overheating networking gear can impact performance.
It seems like typical WiFi disruption. 2.4 GHz is a very busy frequency, overlapping with many devices—like Bluetooth, cordless phones, wireless mice and keyboards, microwaves. At 5 GHz it travels farther but has less range and penetration. In the US it competes with radar signals (DFS channels) and other services. My suggestion is to try a WiFi analyzer app to check the spectrum. That might help you optimize your connection. However, there are no assurances with WiFi performance.
