Hi,

They mention a common firewall feature, I wonder if this means that inbound connections are dropped (as would be the case if they used NAT) or some other restrictions are in place compared to SLT ADSL for example.

Currently we have hosted mail/ftp/web servers inside the network. Further some web services have been hosted on custom ports for testing purposes. So far there not have been any problems in inbound or out bound traffic.
But DialogBB had some problems in the SNR rates and some engineers from the foreign network equipment supplier visited our office to diagnose and optimize the connection. It was around 16dB SNR on downstream but they were able to increase it to 32dB for both directions.

good to know they are tweaking this.

have you noticed any link quality changes due to weather? might be too soon to say.

also what times did you do those speed tests at?

Hey,

first of all I wanna know about Prices…

because some ppl said me WiMAX charges on Downloaded Data Basis & someone said it’s not..

& how much on installation?

PS: I already sent a mail to your MSN account…

Gayantha,

Prices are same as they given in the presentation and there are no quotas etc. It’s a fixed price for the maximum bandwidth. But only problem I see is that they only say its “SHARED”. Therefore there are no QOS ( Quality of Service) guarantees. It could be zero to maximum bandwidth. I think DialogBB should come up with minimum QOS levels in there agreements in future. Because any international ISP has some QOS level guarantee in the agreement and its enforced form there consumer protection laws. But it’s very unfortunate that not a single ISP in Sri Lanka gives any QOS guarantees for Broadband connections

Nirudha,

As other wireless technologies it has problems related to radio singles. But as I understood in Wi-Max they have created software and hardware to dynamically adapt to these problems. I have seen it changes modulation from QPSK to BPSK vice versa. But I don’t think its stable as a Microwave link but it’s intelligent at different level of the network stack to adapt to different conditions.

Note - Please correct me if I’m wrong, because I’m not a network/ engineer

I got the 2mbps package yesterday. While doing initial tests I actually got up to 1.6mbps (bittorrent) downloads and I was REALLY happy.

But after a few hours my speeds dropped to sub 200kbps (more like a home ADSL package) and it has not gone over that since then.

I was convinced it must be a SNR issue for such big difference but all the technical support guys seem to be spoon fed the term “shared bandwidth”.

Quite a disappointing performance so far. Hopefully we can track performance as more users come on board.

I got the 1 Mbps package installed at my place and the quality of service has been pretty good so far.

This morning I tested the connection speed during heavy rain and it was a little bit slower. Not sure if it’s due to bad weather or the increased traffic during office hours on a weekday.

hey Tao,

What is the maximum speed you can get on a large download using a download manager (and multiple download streams)?

Seems like that WiMax and ADSL still has the same problem in SPEED.I was thinking to change from my ADSL to WiMax but its better to wait for some time guess it will take a very very long time for us to get a connection like FiOS http://www22.verizon.com/content/consumerfios/packages+and+prices/packages+and+prices.htm

Hello! Good Site! Thanks you! qecagnonnmgzz

Hi,

Have they provided you with the static IP and the reverse DNS entry to go with that?

We’ve got a PRO + package about a month ago, the IP was finally fixed after numerous mails and phone calls. Still waiting on the reverse DNS.

Hi Raditha,

Yes. They provided a static IP at the time of installation and we never had a problem with them. Even after a week or two of installation a team came and adjust the antenna for optimum signal levels. I didn’t ask for the reverse DNS because my previous experience with local ISPs for reverse DNS is not that good. Please post a comment when you get the reverse DNS, so I can also ask it from them.

Hey folks,

can someone give me the details of how much they charge for monthly for postpaid residential package. I would really appreciate this help. because I am living abroad and looking to get broadband line to my house at home.

You can find the details from their site. There are 4 packages on offer.

I have a 2mbps connection. Network goes down several times in a week. we have shared the netconnection with my friends. Had numerous calls and finally they said they have a FAIR USER policy, means we can download 8GB a day. Its waste for companies to take this type of connection ah?

Still waiting on my line to fire up.. actually waiting for the installation guys. Well about the FUP, its quite unclear about many things. But as people who use connections in Australia (Majority of lankans now) are def used to this and its even worse there cos after the FUP the speed goes to 48kbps and remains till the next bill cycle.

Thia is shit they are blocking Bittorrent
