Find your maximum internet speed by checking your connection details and using speed testing tools.
The connection seems to be DSL-based, with speed decreasing as you move farther from the central office or remote unit. This performance isn't just affected by distance but also by the quality of the phone lines on the poles. Poor connections may lead to interference, which could further impact the signal. It appears this is the maximum achievable speed under current conditions.
Update: I switched to a VDSL router, but the issue persists. I thought upgrading might help, though these devices usually don’t boost speeds instantly. The problem is getting worse, dropping from 1024KB to 254KB and now around 1MB for more than eight Wi-Fi devices. It’s still not working well.
I think there might be a problem with your home wiring or the ISP's network. You could just express your frustration. Your provider’s responsiveness can vary depending on their priorities and location. For example, Verizon seems to have stopped supporting DSL and is neglecting its copper network. This is likely because they prioritize fiber, 4G, and 5G areas. Testing your DSL setup might help identify the issue. If you can compare your internal wiring with the ISP’s connections, it could point to the problem. With cable internet, simply disconnecting the external wires and connecting them directly to the modem would work. With DSL, our copper line is already installed near the utility pole, so we can’t get service from AT&T anymore—they don’t want to upgrade the area.
Another brief update: I've upgraded the wiring. Switched from the old tin cable to a new copper one as recommended, hoping it would fix the issue. It really helped in many ways. The stats on my router are now accurate, except for the main concern—the actual line speed. It's still around 1MB down with a 254KB up. I tried everything possible, but the speed drop remains. All the numbers look good, but the real problem—getting the expected bandwidth—persists. Logically, it must be a technical issue from their side. As you mentioned, my only option now is to vent and express frustration. I’ll switch to sicko mode since this ISP and their staff just don’t know what they’re doing. I’ll also post another update about the new stats in hopes of clearer guidance. Thanks for your support!
I think there’s definitely an issue with the line. The noise margin should be around 6dB, which is what we’re aiming for. All the data we have suggests you should be hitting that target if everything is working properly. The interleaving values also point to some problems. After you changed the cabling, maybe give the router a break—turn it off for about 30 minutes and see if it recovers. If the problem was on your side, it might need time to fix itself, though I’m sure it’s more likely a line issue.
