Troubleshooting Network Adapter in a Windows 7 Ultimate 64-bit Installation

How the problem surfaced:

I had purchased a Windows 7 Home Premium 64-bit laptop from Toshiba on which I was planning to do some work. Then Windows 8 Preview became available. This was installed on a second partition of this machine. Sine Home Premium does not support many of the things I wanted, I decided to buy and install Window 7 Ultimate 64-bit. I bought the Windows 7 Ultimate 64-bit from I installed it on the Windows 7 Home Premium partition. The installation went well except for a very serious problem. I could connect neither to the internet nor to the other computers in my network (there other windows 7 computers connected to the home group). Naturally I tried to see if my network card was OK. I got a positive response to my ping and also the second partition had no network-related problems. Digging deeper I found the Network Adapter node in Device Manager was marked as ‘Other Device’ and the details from system information is as shown:

Besides the network related drives quite a few others were also not present. A high volume storage device connected during the installation to a USB drive got corrupted and the message thrown was ‘format this drive’.

I used my Repair Disc for the Home Premium to get back into the original OS and looked at the needed files for the adapters. The next section shows what they were. Although I could determine the needed files for Wi-Fi and PCI Controller I was not sure of what the other items in the previous picture of component errors including the ‘Base System Devices’

Reinstalling Windows 7 Ultimate x64

Since I could get to these files from my other partition, I decided to try and reinstall Windows 7 Ultimate x64 using the driver files available through my other partition. When I tried to do so, I got the Windows message that the files are not digitally signed.

I quote from the General tab of the properties of the driver,

“Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)”

Hunt for the digitally signed drivers

I had to do an extensive search for this elusive element. The network related driver names are right. Attempt to point to the driver on the computer brings up the above error messages and sometimes comes up with the statement that the drivers are up to date.

Trying to get the Intel® WiFi Link 1000 BGN driver from the Intel site landed me on this page shown here:

Well this could not come up well on my IE9.0 (done with errors) and so I needed to install Mozilla. This was still not enough since you need an agent from a third party shown in this next image.

Which of course needed the latest Java and I had to get more of my caffeine shots.

With all this the automatic discovery of drivers was not completed after running the program for couple of hours! I thrashed the program and sent an angry note to Intel regarding my views of this tool.

During this hunt I searched everywhere and there were quite a few programs I downloaded which were supposed to do the discovery and automatic update part. The problem was, there was no network connection. Most of them needed registering which means $$ and some of them downloaded at a minimum 7_zip, Real Player, Google Chrome besides wanting to clean of my registry etc. Fortunately the network was not working and I did not want to use them.

 Going to Toshiba site looking for Network adapter drivers was easy since I knew the exact model of my laptop. However the filtered information gave me only for Windows 8 where as I was looking for Windows 7.

Fix for the Realtek PCIe GBE Family Controller

The following site provided the driver to update the driver on the computer:

After the update the Device Manager displayed the controller as shown:

The details of the updated driver are as shown:

Compare the existing and updated versions.

Fix for the other devices marked Basic etc.

I tried to download the following:

Intel WiFi Link 1000 BGN Driver for Windows 7

From the Softpedia site here:

But the setup.exe file did not find the driver for the WiFi on my computer but it did upgrade couple of the drivers marked ‘Basic System Device’ all related to the System Devices node in the Device Manager.

Here are some screen shots of what they were:

It is possible that these were removed and devices with the same functionality were added during an upgrade from another site (see last section).

Upgrading the Intel® WiFi Link 1000 BGN

The driver needed to upgrade was finally found here:

The sp54841.exe file when executed created files in the System32 folder which were used during the upgrade operation. It can be in either of the folders; Drivers or DriverStore.

Here are some property pages captured after the upgrade:

Fix for Universal Serial Bus Controller
With the above upgrades there was the USB Controller still needed repair:

A fix for the above was found here:

The file 8ay210ww.exe (67.5 MB) was downloaded and installed. I am guessing that it negated an earlier install and brought in files that would make the controller install without errors. The files related to ‘Renesas’ were installed during this installation.

The Installation of Windows 7 Ultimate 64-bit was finally completed. However it was found that during the process the computer refused to recognize my Windows 8 Preview in the second partition. The boot menu did not show an option to boot to the second partition. Then I installed the free program EasyBCD2.2 ( which enabled me to see the second partition during the boot. 

However it turned out that some changes might have influenced the second partition that corrupted the files (?? Need explanation here). Fortunately I had the original Windows 8 Preview and I installed the same in the second partition.

This finally brought me back to the position I wanted to be in:

1st Partition: Windows 7 Ultimate 64-bit
2nd Partition: Windows 8 Preview

The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
As organizations realize the scope of the Internet of Things, gaining key insights from Big Data, through the use of advanced analytics, becomes crucial. However, IoT also creates the need for petabyte scale storage of data from millions of devices. A new type of Storage is required which seamlessly integrates robust data analytics with massive scale. These storage systems will act as “smart systems” provide in-place analytics that speed discovery and enable businesses to quickly derive meaningful and actionable insights. In his session at @ThingsExpo, Paul Turner, Chief Marketing Officer at...
DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability. In his session at DevOps Summit, Charles Kendrick, CTO and Chief Architect at Isomorphic Software, demonstrated examples of com...

Learn how the Adobe Marketing Cloud can help marketers embrace opportunities for personalized, relevant and real-time customer engagement across offline (direct mail, point of sale, call center) and digital (email, website, SMS, mobile apps, social networks, connected objects).
The Internet of Everything is re-shaping technology trends–moving away from “request/response” architecture to an “always-on” Streaming Web where data is in constant motion and secure, reliable communication is an absolute necessity. As more and more THINGS go online, the challenges that developers will need to address will only increase exponentially. In his session at @ThingsExpo, Todd Greene, Founder & CEO of PubNub, exploreed the current state of IoT connectivity and review key trends and technology requirements that will drive the Internet of Things from hype to reality.
Two weeks ago (November 3-5), I attended the Cloud Expo Silicon Valley as a speaker, where I presented on the security and privacy due diligence requirements for cloud solutions. Cloud security is a topical issue for every CIO, CISO, and technology buyer. Decision-makers are always looking for insights on how to mitigate the security risks of implementing and using cloud solutions. Based on the presentation topics covered at the conference, as well as the general discussions heard between sessions, I wanted to share some of my observations on emerging trends. As cyber security serves as a fou...
Continuous processes around the development and deployment of applications are both impacted by -- and a benefit to -- the Internet of Things trend. To help better understand the relationship between DevOps and a plethora of new end-devices and data please welcome Gary Gruver, consultant, author and a former IT executive who has led many large-scale IT transformation projects, and John Jeremiah, Technology Evangelist at Hewlett Packard Enterprise (HPE), on Twitter at @j_jeremiah. The discussion is moderated by me, Dana Gardner, Principal Analyst at Interarbor Solutions.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
PubNub has announced the release of BLOCKS, a set of customizable microservices that give developers a simple way to add code and deploy features for realtime apps.PubNub BLOCKS executes business logic directly on the data streaming through PubNub’s network without splitting it off to an intermediary server controlled by the customer.

I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
Apps and devices shouldn't stop working when there's limited or no network connectivity. Learn how to bring data stored in a cloud database to the edge of the network (and back again) whenever an Internet connection is available. In his session at 17th Cloud Expo, Ben Perlmutter, a Sales Engineer with IBM Cloudant, demonstrated techniques for replicating cloud databases with devices in order to build offline-first mobile or Internet of Things (IoT) apps that can provide a better, faster user experience, both offline and online. The focus of this talk was on IBM Cloudant, Apache CouchDB, and ...
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
There are over 120 breakout sessions in all, with Keynotes, General Sessions, and Power Panels adding to three days of incredibly rich presentations and content. Join @ThingsExpo conference chair Roger Strukhoff (@IoT2040), June 7-9, 2016 in New York City, for three days of intense 'Internet of Things' discussion and focus, including Big Data's indespensable role in IoT, Smart Grids and Industrial Internet of Things, Wearables and Consumer IoT, as well as (new) IoT's use in Vertical Markets.
Container technology is shaping the future of DevOps and it’s also changing the way organizations think about application development. With the rise of mobile applications in the enterprise, businesses are abandoning year-long development cycles and embracing technologies that enable rapid development and continuous deployment of apps. In his session at DevOps Summit, Kurt Collins, Developer Evangelist at, examined how Docker has evolved into a highly effective tool for application delivery by allowing increasingly popular Mobile Backend-as-a-Service (mBaaS) platforms to quickly crea...
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
