Hello everyone.

I am currently stationed in Iraq and I get my internet wirelessly from an internet provider who in turn gets his internet from a big provider in the city who leases a line from a large satellite company in the UK or Germany or wherever in Europe.

I am the last in the chain to get the internet off of these guys. Some internet providers choose to skip the first guy and buy their own satellite dish and deal straight with the UK/DE internet provider.

Anyways. My setup is like this: On my desktop machine which I am using as a gateway to my laptop. I have turned on Windows ICS and connected a LAN cable to my laptop. .. On this desktop I have a Dlink DWL-G520+ card. This card is connected to an R P-SMA-Male to N-Female connector. Then connected to a LMxx Coaxial RG cable which is connected to a Hyperlink Parabolic 24dbi antenna. (I hope I got these names right).

Now comes the annoying part. The configuration:
The way I have the dlink card setup is pretty simple. Through the dlink utility I have selected: Short Preamble, 54meg TX and speed enhanced mode Enabled. **Picture 1**


If I were to go into the device manager and select the advanced settings for the card I am faced with many options. For example D-Link has an option that says “Desired TX Power” and the options are Auto, Level 1 through 5. No real explanation as to what is 1 through 5.
Of course there are more settings as you can see in the picture. **Picture 2**


Another thing I did was use TCP-Optimizer to fix my MTU and other values. I selected the optimal settings. And yes I did notice an improvement.

Now comes the real part which I need help with.

My ping times are decent. Here is an example: (this is the ping from my laptop to the internet provider). Same results are seen if I ping from the desktop/gateway

At times I face the dreaded Request Time Out but most of the time its ok.

Now the speed part. The provider has given me the following speeds (Or so he says. No way for me to really verify). 256kb Down and 128kb (yes. That’s kb NOT KB).

According to Google earth I am about 1.35 Kilometers away from the internet provider.

I am not expecting Cable modem speeds or even a T1 but I am having pains at times opening pages. I can tell there’s a lag getting to the DNS server because once a website URL is open its smooth sailing from there so what I have done to work around that is use an anonymous proxy server. Sometimes I turn it off and go straight to the provider.

Different scenarios at times…
I try to open google.com and I get a Firefox error saying Server Not found or The connection has timed out error.
I enter in a proxy from an anonymous proxy list and I can load google.com
But when I when I ping I get a reply. OR
I don’t get a web page. I don’t get a ping but when I check the dlink utility I see there’s an active connection going which leads me to believe that his server maybe down.

Ok so that’s 1 problem. The biggest one I am suffering from is this: when I download something in the background or have one webpage open and try to open another I am smacked with an error. It’s as if its saying to me that I can only do one thing at one time.

I don’t know if this is windows ICS not distributing the bandwith properly OR I am reaching my bandwith cap limit

I am no expert on wireless.

How should I have the desktop machine setup?

Is there a conflict between the power of the antenna and the lame dlink card?

What can I do to improve my performance? According to the provider he’s given me the highest speeds he can give a subscriber.



I can say that at times I do notice things are going fast but for the most part they are a pain.

In regards to interference. Ha. Well that’s a crazy one. If I use network stumbler and scan the area I can pickup LOTS of internet providers. It seems that’s the business to be in here in Iraq right now.

My provider is using channel 6. At the moment I am seeing about 4 (or more at times) other signals on the same channel.

No NIPR available from your unit/FOB? Or too slow?
