Divit Dsouza asks:
I have a D-Link 2750u router and it supports a downstream of 24 Mbps. My broadband plan is 4 Mbps. The summary page of my router always shows the downstream as 2047 Kbps exactly and always. I have tried other modems/routers also and the down speed is exactly and always 2047 kbps (summary page). Speedtest.net says my download is at 1.75 Mbps.
Is there some kind of setting that is capping my speed to 2 Mbps? Thanks.
My card: Realtek RTL8168/8111 PCI-E Gigabit Ethernet NIC
MoBO: Intel DG31PR

July 13, 2012Since you have DSL, you may be seening several things here. The longer the distance from the CO and DSLAM, the more distortion/jitter will appear on the line. Higher temperatures increase the resistance on the line (remember it is still running on copper). These (along with other) effects will reduce your overall speeds as your modem continutes to negotiate down from your max until it has a reliable speed it can maintain (considering retransmissions, dropped packets, etc).
Even though the above mentioned items can reduce your connection speed, you should also verify with your ISP to ensure that your line has been provisioned appropriately.
Actually, I’m no more than 2 km from the exchange. And they have laid new cables, though it’s still copper. And the wiring in the house is done so as to get no noise at all and precautions are taken.
July 13, 2012I just need to make sure that something in my computer is not capping my speed or does changing some settings solve this. The download speed in the summary page shows 2047 kbps always, there is not even a slight change. While downloading I get exactly 216-217 kBps always.

July 13, 2012If you check your contract it will proberly say UPTO 4Mbps which is because of the reasons outlined by Bruce.
My plan is for 24Mbps but the max I get is 14Mbps.

July 13, 2012You need to see your contract first. If it was said “Up to”, then it means it will not achieve the maximum they offer, but they have minimum speed guarantee. Others possibility reasons is your connectivity is not 1:1 connection, which means it is a shared connection, with the minimum guarantee is 2 Mb.

July 13, 2012In general it usually relates to how far you are from your nearest exchange. Also if you are using wireless also has an effect on the speed.

July 13, 2012Divit,
Unless you have a *very* unusual setup, this is nothing to do with your PC’s configuration. As Bruce explained, ADSL speeds depend on a number of environmental factors, and in fact 2km is close to the limit of distance from the exchange, so it’s entirely possible that this is the maximum achievable speed.
You are also unlikely to get a higher speed by trying a different router/modem since this will necessitate disconnecting the existing one and connecting with a new one, which will start at a slow speed and build it up… I only have two pieces of advice:
1. You should keep your router/modem on *all the time*. Switching it off or restarting it will count as a “reset” and your router will lower its speed.
2. If you still get no joy, contact your ISP. The diagnostic tools they have should allow them to get to the bottom of the matter.

July 15, 2012speednet’s speed test is affected by the distance from you to its servers.
also, when buying an internet plan labelled 4Mbps, it does not mean you will have constant speed, maybe the speed on your router page is local speed (connection to services in your country)
i suggest you check with your ISP or check the terms in your data plan.

July 17, 2012Like the others are saying, “your mileage may vary.” 2km is actually pretty close to the central office switch, but your ISP could have performance issues, could be line issues, even the way your router is measuring throughput.
Go to speedtest.net and run the test several times during the day, over several days time, to really get a good feel for what you’re getting.

July 23, 2012Looks like the problem is solved now Router shows the linkspeed as 4095 kbps down and 509 kbps up. Speedtest.net reports 450 kBps
And they even raised FUP to 10 GB

October 22, 2012R u using wireless router are with line I think via line there is so many problems to reach u exact speed but there is so many backdrops in using line I am also facing same problme some post the exact solution for this
