So in part 1 we talked about the devices I have purchased, now let’s dive-in and talk more about the implementation.

So I need the network to cover two and a half floors (roof is a half floor because it has two rooms). Each floor has around ten Ethernet wall plug and two/three access points. There’s also few cameras around the house, nine on the ground floor and four for the other floors.

To have a good network and wireless speed I have to pay careful attention to the backbone implementation of the network. So while I’m upgrading my home network infrastructure I’ve decided to also upgrade my current in-wall cables from Cat 6 to Cat 6A for future proofing. I have plans for purchasing a server and a separate SAN in the near future to expand and upgrade my home lab and media servers.

So next how many core switches do I need? With the number of required ports and because of having small size in-wall cable pipes, I have settled with two 24 ports switches (US-24-250W) for each floor except the roof. I would’ve preferred the US-48-500W with 10 gaigabit SPF+ ports for a backbone network switches but those 48 ports are more than twice what can be fitted through the cable pipes.

All cable pipes end up on the stairwell and they’re distributed in a such a way that each floor pipes ends up on the stairwell of the floor above. So ground floor cable pipes end up on the first floor stairwell. Therefore, core-switches are placed on the stairwell for each floor.

I couldn’t replace all Cat 6 cables because cable pipes are too small so for some points we couldn’t fit in another Cat 6A cables. Also I’ve decided to connect two cables between each core switches and home lab for Link Aggregation and faster speed.

A month later I’ve decided to add UPS to my home switches and gateway which in turn provides power to all my PoE devices (small Unifi switches, AP, and cameras). Should provide at least 40mins of backup power with my latest test. I bought also another bigger UPS for my NVR/Media server to keep everything running and recording when there’s a power outage. I’m planning to increase the UPS run-time in the future when I can budget for it.

As you can see on the pictures above I’m using patch panel for two reasons; to keep the cables tidy and minimize touching any core cables to increase longevity. Maybe it’s an overkill for a home network but at least it feels more professional and I’m proud of it.

So I decided to upgrade my home network for several reasons:

• Dodgy Wi-Fi connection
• Wi-Fi dead spots around the house
• Monitoring network activity and who’s using downloading a lot and impacting other’s experience

So after exploring and searching I’ve settled with the Ubiquiti Unifi ecosystem. I’ve been following the company for many years now and I’ve been a very fond of it for long time now, and the family are complaining about the dodgy Wi-Fi connection gave me a good excuse to upgrade my network infrastructure. And by choosing Unifi I get the added benefits of

• PoE built into the switches rather than relying on PoE injector for each camera around the house
• PoE end-point switches and AP so less cluttering and centralizing power feed for the home network so I can add a UPS in the future for powering my network and cameras in the event of power outage
• Unify experience across devices with a single dash board

But that doesn’t mean that there’s no cons on changing my network infrastructure. In fact, because I’m using pfsense, I’m going to lose some flexibility when moving to a fully Ubiquiti Unifi solution like load balancing dual-WAN that Unifi for some reason doesn’t seem to be able to provide a workable solution for that.

So I bite the bullet and went ahead and ordered the following devices:

• Unifi AC-Pro UAP-AC-Pro x3
• Unifi AC Lite UAP-AC-Lite x3
• Unifi Switch 24 Port US-24-250W x2
• Unifi Cloud Key UC-CK
• Unifi Mesh UAP-AC-M-US
• Unifi Switch 8 Port US-8 x3
• Unifi Security Gateway USG

But unfortunately we didn’t have a dealer for Ubiquiti here in Kuwait so I had to purchase those devices online.

Some might be wondering why a lot of devices. The reason is that I need to cover 2 floors and a half (the gym room), and the garden. So ground floor will get two Wi-Fi AP and the first floor will get three Wi-Fi AP because one half of the floor has many walls that one AP will not be enough to cover that half.

And because I’m upgrading the network I decided to also upgrade the network cables around the house to Cat6A for extra reliability and future compatibility for 10G speed. I bought a 100 meters roll (300 FT) and at the end only 70% of house cables were upgraded to Cat6A because 100 meters wasn’t enough. That’s an additional $300 for the cable and $500 for the handyman.

Most of my purchase came from Amazon and bhphotovideo.com. I couldn’t find everything on Amazon (out of stock) so I got USG, UAP-AC-Lite, and UAP-AC-M-US from BHPhotoVideo. All shipped to New York Shop&Ship office then forwarded to Kuwait. That’s around $700 just shipping the item from NY to Kuwait. If you’re wondering, there’s no Ubiquiti dealer/shop in Kuwait.

Note: This project was completed back in January 2018.

to be continued on Part 2…

A problem I was facing recently, that the JSON was being receive properly on Firefox 3.6 my work development machine. Finished the project and deployed it. I haven’t tested it on other machines, how clever am I?! I opened my laptop to see how it would appear on other browsers, and shockingly, it wasn’t working at all!

After spending hours trying to locate the line where the error occurs and find out what’s the problem it turned out that I have to decode the JSON output before sending it. I wasn’t using any PHP built-in functionality for JSON, that’s because at work, we are still using PHP4 which has none. I was basically writing the JSON output explicitly. The text output can contain some special characters that need to be encoded and escaped before sending it. After digging around a bit I found out a solution from this post. Everything is pretty much explained there.

In a nutshell, you’ll have to use json_encode() to encode the data from an array and then output it. A JSON library is provided along with that post. There is also a decoding function, but I haven’t use it since I’m receiving my data on a javascript.

A security enhancement was added to Flash Player sometime ago that disables getURL to function properly in Actionscript 2.0 of Adobe Flash. This could be an issue for some as in my situation when I created a banner for MET to celebrate the independence & liberation day of Kuwait.

The issue occurs if you are targeting a different domain than the current domain where the SWF/HTML file is hosted. I’ve also heard reports that it can occur if the SWF and HTML file are located at different location even if at the same domain host. I haven’t tested the latter so I can’t confirm or deny it.

Anyhow, to resolve this issue, all you have to do is change the allowScriptAccess attribute on the <object> tag to have the value “always”. You also have to add <param name="allowScriptAccess" value="always" /> or edit it to match it if it’s already there.

So at the end, your code has to look like this:

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=10,0,0,0" width="955" height="88" id="SWFID" align="middle">
<param name="allowScriptAccess" value="always" />
<param name="allowFullScreen" value="false" />
<param name="movie" value="FILE.SWF" /><param name="quality" value="high" /><param name="bgcolor" value="#ffffff" /> <embed src="FILE.SWF" quality="high" bgcolor="#ffffff" width="955" height="88" name="SWFID" align="middle" allowScriptAccess="always" allowFullScreen="false" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer" />
</object>

This issue is explained in more detail at the official knowledge base of Adobe here and here.

So you are now one of those people who found out about Zune and got really turned down by Microsoft for preventing us to access the device and the Marketplace just because we do not live in the US? Don’t worry because I have the ultimate workaround.

Since the released of Zune Software 4.0 and the integration of Zune Marketplace to the Xbox 360, Microsoft has stepped a big leap forward into the Music and Entertainment industry. The Zune Software 4.0 is user-friendly and much more responsive than its competitive the iTunes in the Windows platform and the Zune HD device is awesome and feels much more robust than the current iPods. And thanks to the Zune Pass, the Zune Marketplace now provides unlimited number of music at the tip of your hand to listen to or download, of course, with DRM lock. The Zune Pass cost only $15 USD monthly but the problem is that if you are not based in the US, you won’t be able to enjoy the Zune Marketplace, heck, you won’t even be able to buy Zune. To be fair to the Microsoft folks, I think those roadblocks were necessary for license music in the Marketplace whether the Zune team really wanted to block international users or no.

In this article I’m going to talk about how to own a Zune HD and get yourself hooked up with the Zune Marketplace with the full features of Zune Software 4.0 just like living in the states.

Get the Zune HD

Officially the Zune HD is supported and sold only in the states but you could find sellers in ebay that would happily sell it and ship it to your country but for an extra profit.

Another alternative is to buy Zune HD through Amazon or any other retailer and ship it to a “shipment forwarder company” in the states that ships anything they receive under your name to your home address. Basically, those types of companies will provide you with a US mailbox and an address, and if anything is mailed/shipped to that address it will be forwarded and shipped to your home. I personally use Aramex’s Shop&Ship but if you cannot use Aramex for any reason, you could always use DHL since they provide a very similar service. This kind of shipping service is available in my country and I’m not sure if it is available everywhere.

Grasp the Full Potential of the Zune Marketplace

Zune HD can play all music and videos in that’s already in your hard disk and playable by Zune Software 4.0. Now, here what really made me ditch iPod and iTunes, it is the Zune Marketplace. The main reason I made the move from iTunes to Zune Software is that I can get unlimited music with Zune Pass as I mentioned previously.

Now it is time to do some changes in your computer. Follow the next instructions before opening the Zune Software for the first time. You can download Zune Software from here.

Accessing the Zune Marketplace

In a typical non-US computer you won’t see the Marketplace & the Social tab in Zune Software, however, you could easily solve this by setting your location to US. To do that, go to Control Panel –> Clock, Language, and Region –> Change location, then select your location to “United States” [Windows 7].

Now you should be able to see the Marketplace tab after restarting the Zune Software.

Get a Windows Live Account

Now you need to register for a Windows Live ID which is the generic account for all Microsoft services, or you could just grab a new Windows Live or Hotmail email which is also considered as a Windows Live ID. You could use your existing Live email.

Just ensure that in your profile your home address is set to US. You could use any US-based address you want. Heck, you can use any of Microsoft offices address 😀

If you followed previous instructions you should be able to browse the Zune Marketplace and play with it. But wait! We are not done yet. Follow next instructions if you want to be able to buy Music and download them.

Note: To login successfully in your Zune Software, your PC location has to match the location in your Windows Live profile which should be US by now.

Purchasing Music from the Zune Marketplace

To purchase Music from the Zune Marketplace you’re going to need Microsoft Points which is the currency being used for the Zune Marketplace and it is also the same currency being used for the XBox 360 Marketplace. You can purchase Microsoft Points online by the Zune Software but the problem is that Zune Marketplace only accepts US-credit cards. Fortunately, I was able to overcome this roadblock with the Xbox point card.

You can purchase an Xbox point card by either asking a friend from US to buy one for you and send you the card code, or you could head to ebay and buy one. Some sellers in ebay will just email you the card codes regardless of your location which is perfect for a fast solution. I personally buy from GSG online retailer because I’ve bought several Microsoft Points from him already so I trust him, and he usually send the code in less than 24 hours.

Now that you have the card codes, launch Zune Software in your PC then go to Settings –> Account –> Redeem code. Enter the code and you’ll be redeemed with Microsoft Points which can be used to buy anything in the Zune Marketplace.

You could also use those points to purchase videos on the Zune Marketplace but you’ll need to workaround it more to download videos. I’ll talk about it later.

Zune Pass

Want to enjoy the ultimate experience of Zune? Then Zune Pass is your salvation.

Again, the Zune Marketplace will not accept a non-US credit cards so you won’t be able to purchase Zune Pass on your own. It took me a lot of Googling (Bing suck!) to figure out alternatives which is the Zune Pass Anywhere retailer. It provides you with a Zune Pass but for a higher price and they will need to access your account so you’ll have to submit your password. Basically, they will access your account and buy a Zune Pass.

Alternatively, if you have a friend in the states you can ask your friend to buy you a Zune Pass card from Best Buy for $15 and email you the card code.

Videos

So far you should be able to download music yourself with no problem. The experience is not complete without the ability to purchase videos from the Zune Marketplace or downloading it. Easy, get a VPN (aka Virtual Private Network) for as low as $40/year from some firms.

I use Witopia but there are many other companies that provide VPN and you probably could even find lower prices. But you have to ensure that the VPN is based in the states. By the time I write this article it seems that the video download works even when the VPN service provide you with an anonymous-IP.

As soon as the video starts downloading, you won’t need VPN anymore. If your VPN connection is slow, you could pause the download then disconnect your VPN connection and resume the download with your regular connection.

After doing the first download, it doesn’t seem to need VPN anymore to download any additional videos. I don’t know the actual reason behind it but I can guess that because I have already purchased a Zune HD and linked it to my account.

Finally…

What Microsoft has done with Zune HD and Zune Software 4.0 is really incredible. If you were one of those lucky people who own a Zune HD and Zune Software, you officially own the modern device and software. They are both much user-friendly, easy to use and feels much more modern than the iPod-like interface. If you are a tech-savvy you are probably bored from the iTunes and iPod interface which feels really out-dated. You would also notice the big gap in performance with Zune Software 4.0 compared to iTunes 9.1.

Happy Zunning!

Purchasing the Novatel Mifi 2352 is a procurement that I’m never going to regret. Not only I can access the Internet with my phone through a wifi router that can fit in my pocket, but I can also use my PDA and Zune HD to access the web at the same connection (subscription) while on-the-go. Sharing my connection with my Internet-savvy friends is also a big plus. In this post I’m not writing a review about the device but a quick test. Why should I write another review when there are a lot of reviews online?

The following test is based on my connection which is an HSDPA connection from Viva Telecom in Kuwait. According to the carrier, my subscription speed can reach up to 7.2 Mbps. I bought the device from Cameo store which is located in Hawalli, Kuwait, for 72KD. And it comes with various wiring options and a small how-to-get-started print.

Speed Test

Here comes the speed testing in Salwa area, but keep in mind that lots of variables can game here. I just want to give you a sense on what this device is capable of. I’m not doing a scientific or geekish connection test, I’m just doing the regular method of quick speed testing for a regular web citizen to understand.

I’m going to do the speed testing with both the Mifi 2352 and my old USB dongle Huawei E180 for comparison. I’ll use the same sim card on both connections. Note that both devices supports up to HSPA speed, that’s up to 7.2 Mbps for both devices and it’s stated on the datasheets of both devices.

The image above represent the status of the connection on the Mifi 2352 device. As you can see, it is connected by HSPA technology (HSDPA & HSUPA). I did the test to a server located in Washington DC by Speakeasy. The first test of the Mifi 2352 resulted about 1.74Mbps download and 0.27Mbps upload. I switched back to the Huawei USB dongle and the tested result was 2.19 Mbps for download and 0.24Mbps for upload.

I did both tests again and the result was:

• Novatel Mifi 2352: Download 1.09Mbps – Upload 0.28Mbps
• Huawei E180: Download 2.92Mbps – Upload 0.21 Mbps

Definitely there are differences in the performance of both devices. It seem that the USB dongle is faster on downloading. Again, this is a quick-test to have a sense of what to expect from the Mifi 2352. It’s not a scientific test and it is not reliable testing method and I’m doing this in uncontrollable testing environment.

I’ll do more testing later and then I’ll report back.
