Slow DSL connection with D-Link DSL 584 T router

Hi everyone!

I'm having some trouble with my DSL connection.

It’s incredibly slow; sometimes I have to click a link multiple times just to get it to respond. Pages load painfully slowly or don't finish loading at all, forcing me to hit "stop" and then "refresh" just to see the full content. This happens whether I'm using Internet Explorer or Firefox.🤷

I'm using a D-Link DSL 584 T router connected to two different PCs. Both computers are experiencing the same lag. It wasn't always this way—the DSL worked perfectly for the first two months—but things started acting up about two weeks ago.

I've already installed all the latest antivirus and antispyware software and cleaned up both PCs, yet the connection remains sluggish.

Does anyone know what might be causing this or how I can fix it?

Thanks in advance!😉

AT&T: 1-800-900-0000, AT&T Customer Service.
And honestly, sometimes the most effective fix is just turning the device off and back on again.😉

Look, you might want to try disabling the Windows Firewall and turning off your antivirus entirely for a moment. It’s entirely possible those programs are throttling your connection or just straight-up blocking the traffic. If that doesn't fix the issue, then we're looking at a much deeper problem somewhere else in the setup.
If you happen to be running an Intel network card, listen up because there is a specific headache waiting for you. When you go through the driver installation process, the software will eventually pop up a prompt asking if you want to install the Intel Firewall along with it. Most people, being helpful souls, just blindly click "yes," and that is exactly where everything goes sideways. If you’re dealing with one of those cards, do this instead: head straight into your Control Panel, navigate to Network Connections, right-click on your Local Area Connection, and select Properties. Right at the top, you’ll see a thin horizontal window labeled "Connect with" that shows you which network card is currently active. If it's an Intel card, click the "Configure" button on the right and disable that damn firewall immediately. I ran into this exact same nightmare myself, and let me tell you, the second I shut that garbage off, my connection started running like a dream.
I hope that actually helps someone out.

Well, I’ve tried everything on this list, but the connection is still acting up. To make matters worse, AT&T's Customer Service hasn't been helpful at all.

The thing is, my DSL was working perfectly fine for a few months, but then out of nowhere, it started lagging on two different PCs. I'm honestly stumped.

Look, it’s not that they aren't helpful; their Customer Service is actually quite decent. But you have to understand how it works—they run all these checks on their end to make sure everything is hitting their servers correctly, but they aren't allowed to just start poking around in your computer or messing with your settings. They won't tell you exactly what to tweak because if they give you advice and it backfires, they don't want to be held responsible for breaking your machine.
I honestly don't know what else it could be.
For instance, my internet cut out on me recently, too. It was a complete mystery. The connection between my router and my PC was fine, and I could stream DirecTV without any issues, but the actual web browsing was dead. I tried every single troubleshooting step under the sun, but nothing worked. Eventually, I just lost my mind, decided to go nuclear, and formatted my entire PC. Now everything is working perfectly again. I know, I know, it's a bit extreme, but I was at my wits' end. You always end up stuck in that same loop. 🙂

From what I can gather, we're talking about a wireless connection here. It’s possible a neighbor might be piggybacking on your network if you don't have encryption enabled; if they're jumping on your signal, they could easily be hogging your bandwidth and slowing everything down for you.

I’m genuinely sitting here wondering how you managed to jump to that conclusion when, first off, nobody actually mentioned anything about wireless, and second, the D-Link DSL 584 T is strictly a wired router.

Grab the firmware from the AT&T website.
Mine was acting up too—until I actually installed the firmware. Just make sure you're grabbing the right one (wired vs. wireless)

I'm writing this assuming you're talking about AT&T.
I've been dealing with these exact same issues since the moment I signed up for DSL. Honestly, it's been going on for about two years now. I've reformatted my PC more times than I can count, but it didn't help a bit. Pages struggle to open, the connection drops constantly without warning, and sometimes I can't even establish a connection at certain times of the day. Here's how it usually goes down:

Example 1: When I try to connect via the desktop and hit "connect," if there's an issue, the connection fails. Instead, the connection window just freezes on the desktop, and those legendary error pop-ups start appearing, giving me various error codes. Usually, they're numbers like 678, 691, and so on. At that point, I just let the automation try to reconnect itself; if I'm lucky, it might work after 10-15 minutes, but often it doesn't. Sometimes I'm waiting much longer.

Example 2: I'm browsing online and click a link, but instead of opening, it just hangs in time and space. Then, of course, that "page cannot be displayed" message pops up. I know exactly what happened immediately—I look down at the taskbar and see the connection has dropped. If I try to reconnect right away, it usually fails, and those error code windows show up again. Even if I do manage to get back online, it's the same story: links open slowly, everything is slow as hell.

Example 3: Even when I am online, if the connection is clearly weak, I can't receive emails. I get another error regarding sending or receiving mail, warning about server problems (connection with server interrupted). So, technically, I'm connected, but the connection is useless.

No matter the situation, it always points back to one thing: the SERVER is the fundamental problem.

I've suspected all sorts of things—viruses on the machine, Windows slowing down because of antivirus software (in my case, Kaspersky is known as a bit of a PC "slowdown" despite its solid protection, though I think antivirus software only has a minor impact rather than being the primary cause), or maybe the need for defragmentation, clearing out Temporary Internet Files, removing icons from the desktop, or any other "cleaning" activities meant to speed things up. Generally, cleaning the computer of anything that might hinder performance and so on. But I'm convinced that isn't the cause. The problem is singular and quite fundamental:

"AT&T, acting as both the server and the provider, simply can't deliver a decent connection to its customers. Short and sweet."

That’s the crux of it. The connection is weak, unstable, and—if I may say so—fickle, depending on a million different variables. As for the scale of the disaster, it's hard to put a finger on it. It would be helpful if more people spoke up about their experiences so we could actually get a representative sample of what's happening on the ground. I am certain about the poor quality of this connection, but I certainly don't buy the excuses the guys at AT&T gave me regarding why it’s happening. In my view, it's likely because AT&T isn't investing enough in their infrastructure; they want to have their cake and eat it too, aggressively recruiting new users while failing to service the ones they already have. Consequently, we, the naive consumers, end up getting the short end of the stick. I honestly have to laugh when I read about all the "high-speed" packages AT&T is pushing, considering they can barely manage to keep even the most basic tiers functional. That's why I'm still stuck on a basic DSL plan and haven't even considered upgrading to something "fast." Especially not DirecTV, since the AT&T technicians themselves admitted that with a connection this shaky, I shouldn't even bother trying. At least they were honest about that.
Someone mentioned the Customer Service line. I've become quite well-acquainted with them; I probably contacted them hundreds of times before finally realizing they aren't actually capable of helping me. Even though the staff is always fair, I stopped badgering them. To put it plainly, I stopped asking them to fix the line issues directly and instead just insist that my complaint be escalated. That’s it. Usually, after two consecutive complaints, they pass it up the chain. And then, the field crew arrives pretty quickly.
Regarding a recent complaint, a crew from AT&T came to my house a few days ago to figure out why I was dealing with the exact same issue you described. After running some quality checks, they determined that my connection to the server was hitting maybe 2 Mbps, compared to the 10-15 Mbps others seem to get (within the city limits, specifically here in the San Francisco area). They actually clocked it at 1.7 Mbps, if I recall correctly, since the numbers fluctuate constantly. Then they started coming up with all sorts of alibis for why it's like this—citing things like humidity levels, bad weather, road construction nearby (really???) and various other nonsense.
You mentioned the D-Link DSL 584 T router... from what I understand, those have a wireless system, allowing for cord-free (or wired) use. To rule out the possibility of a neighbor accidentally piggybacking on my connection via the wireless signal—something someone else on the forum suggested might be slowing down my PC—they configured it to prevent that. But when they hooked it up to bypass my old Zyxel router and re-tested the connection, the results were the same, if not worse. So, they switched back to the old one because it actually seems to respond better... like fine wine, I guess. lol.
Bottom line is, I've grown accustomed to these headaches you mentioned. I'm on a first-name basis with these problems now, which isn't right because, frankly, this kind of thing shouldn't be tolerated. But what's the alternative? Another provider? But which one... if there even are any? Most of them probably just lease AT&T's infrastructure anyway. There are no other options. Or are there?

We can only pray that some sort of satellite internet comes along, similar to how TV programs work, so we can just bypass the wires, the cables, and AT&T altogether.

Facts! 👍

I'm still using a standard dial-up connection. Over the last year or so, I've run into similar issues where establishing a connection to the server is a nightmare
or when it finally connects, the email sync fails, forcing me to disconnect and try again before it works. I haven't really noticed any actual drops in the line...

It honestly feels like the problems you guys are having with DSL are even worse than what I deal with on dial-up, which is exactly why I've been hesitant to switch to DSL in the first place...

And what about that thing Verizon is advertising: $0.00 you don't have to change your phone number if you cancel?
What is that even supposed to mean?

I've tried everything suggested, but nothing seems to work. Still, thanks for all the help!

Basically, here’s the deal: I try to open a website or click a link, and initially, nothing happens at all. Then, if I hit "stop" and then "refresh," the page starts loading, but it gets stuck halfway through or maybe two-thirds of the way. It just freezes. I have to hit "stop" and "refresh" yet again before the page finally loads completely. It's the same thing with YouTube; the video tries to load, but it stalls out before finishing, making it impossible to watch. Once again, I'm stuck hitting "stop" and "refresh" just to get it moving...

I even tried connecting the router to just a single PC, but that didn't change anything, so I'm honestly stumped.😕

To send this reply, I'll probably have to go through that whole ridiculous loop I described above once more.

PS: Could an IP conflict be the cause here, seeing as I have two PCs running on the same IP address?

I ran into some similar issues with AT&T, and they actually swapped out about three different routers for me before things settled. Once I bumped up my speed, the whole connection felt much smoother—even DirecTV worked perfectly. Eventually, though, the bills were just getting too high—I was paying for mobile, internet, DirecTV, and landline all together at about $200 a month—so I switched over to Verizon. Now, my total for mobile, internet, and home phone is only $90. I ditched the DirecTV, too. It's all one flat rate, except my internet speed is capped at 4 Mbps. I'm using a Technicolor TG788ivn router. I noticed early on that my speeds would tank—sometimes in the evening, and later during the day too—dropping almost to zero. I called Customer Service and an AT&T technician came out to help. He used his own equipment to test the speed, and it clocked in at over 5 Mbps! Meanwhile, when I run tests on my phone, tablet, or computer using www.speedtest.net, the results are less than half of what he saw. When I plug my PC directly into the router with an Ethernet cable, the speed stays above 4 Mbps. It seems like the router is sending a solid signal, but my computer isn't catching it properly—or maybe it's just receiving less than it should? Does anyone have any ideas on what I should tweak? My PC is a few years old and runs Windows 10.

Tyler Hughes12, seriously... You don't honestly think that user has been sitting there since 2008 just waiting for you to finally show up with a solution...
