I got a telephone cable going from a filter/splitter on the wall outlet to the DSL port on the modem, then I usually connect devices via Wi-Fi, if I decide to connect something via ethernet cable I'll use one of the four GbE LAN ports, there is nothing else if not the power cable, I don't even...
Yes I tried the power reset, even tried a factory reset, and since the modem was given me by my ISP, I also asked them about the upload/download values on the user interface, and they said that those values are the actual speeds of the signal going in and out of my modem, my contract with them...
I usually have none, I tend to use only Wi-Fi.
Before this weirdness started I could easily reach 100Mbit/s in download and even more meaning that my PC could reach like 11MB/s when downloading something, but now it downloads files around 100KB/s, and this from sites like Google Drive, OpenLoad...
Sorry, I didn't mention it but the speedtests I'm talking about on the third line have been done through Wi-Fi, so yeah, the download is around 1.5 Mbit/s both via cable and via Wi-Fi.
What the title says.
The modem is a D-Link DVA-5592, FTTC up to 200Mbit, I tried different speedtests on my desktop computer and on 3 other devices (1 iPhone, and 2 laptops).
Talking about my PC, it's using a TP-Link AC600 Wireless Dual Band USB Adapter that goes up to 150Mbps on the 2.4Ghz...
