Broadband speedtest

The other day, an idiot from SLT, tried to convince me that their 512kb/s ADSL line is as fast as a 2048kb/s WiMax link. You can expect people at SLT to make statements like that. Many of them probably hadn’t seen a computer till they joined the company. There is a huge shortage of geeks at Telecom companies in Sri Lanka.

In actual fact, a 512kbps SLT ADSL line only gives about 430kb/s

SLT speed

Notice that this test is being carried out against, SLT’s own speedtest server in Colombo. It’s only about 10 Kilometers away but it still takes 32 milliseconds for a ping. Remember Electronic signals travel at 300,000km/s so this indicates slow routers.

How does SLT perform when you test against a distance server? Much worse.

Right, now let’s see how Lanka Bell WiMax Performs:

Lankabell’s ping isn’t so good either but the upload and download speeds are right up there. You get more than 90% of the advertised speed. SLT’s subsidiary Mobitel has a mobile broadband service. Here is the speed test:

I even stepped outdoors to see if that would improve the speed (since 3.5g signals don’t travel well through masonry).

So in short, if you want an ADSL line that can be compared to a 2mbps WiMax link, you will have to get a 4mbps line.

    Feel like i too should try this too..last time i checked, my SLT-ADSL gave little better results than this. Hope figures wouldn’t drop too low, would hate to go through the process of reporting the issues to them.

      I have stopped reporting slow downs long ago. The same people who claim their link is 2x faster than even the advertised speed will try to convince you that running at half the speed is pretty normal. And sadly, it’s normal for Sri Lanka

    Hey,

    I’m in the market for a new BB connection. Was comparing options. So you mean Lanka Bell BB is faster than SLT?

    Also, do you have any comparison with Dialog’s WiMax solution?

    Cheers,

      I would say go with Lankabell their service has not been perfect but they are better than Dialog and SLT

    I don’t know if you have noticed or not, google hosted domains are very slow on SLT links. I don’t know why it’s so…

    Say you have a custom domain for your blogger, then you have to point cname to ghs.l.google.com, and the pointed domain works perfectly ok in other links such as Lanka Bell WiMax / Dialog HSDPA, but when it comes to SLT links it’s very slow…

    For example you can try http://ramesh.thiruchelvam.com or any other domains you know which are pointing to ghs.l.google.com.

    I have been Using Dialog WiMax 1M download 256 Upload for last 3 years. It was working fine till the end of last year, But Now most of the time the download is horrible as between 50k to 150k. When I informed the technical guys they say that its natural due to shared status. If so what is the basis of my monthly bill. Though this says shared can they come down to that level. I am trying locate a better provider. How is Lanka Bell? can the user have at-least the 50% of the advertised bandwidth.

      I am beginning to sound like an advertisement for Lanka Bell, but i can assure you that they do give you 50% of the bandwidth almost all the time and you can often get 100% of the speed. Which is not something you can say about most providers.

    How about the current speeds at different times?

    I’m fed up with airtel HSPA coz it’s extremely slow during night. Planning to buy a Bell wimax connection and need some comments before buying. Thanks in advance.

      Sorry about the delay. Current speeds are still pretty good.
