Limited Wi-Fi Internet connectivity

While using my preview build of windows 10, sometimes I face the dreaded "Limited Wi-Fi Internet" connectivity issues, where the Wi-Fi adapter seems to be connected to the Wi-Fi router, but full Internet access is not possible. I often attributed these issues to quirks in the preview builds, and a simple computer restart--reminiscent of the older Windows releases--seemed to fix the issue.


But not yesterday, where multiple restarts did not ease the pain. Even deleting the Wi-Fi network and recreating it again did not help. The dreaded "Limited Wi-Fi" banner under the Wi-Fi network name continued to rear its ugly head.


Luckily I had an Ethernet cable handy, so I hard wired the laptop and checked online to see if others have faced a similar issue. There was a considerable number of people experiencing the issue, with various solutions. The one that made sense for me was a bad wireless driver install, which was easy to fix. Before you attempt to replicate the solution, make sure you are connected to the Internet via an Ethernet cable since you'd need to download the latest drivers from the Internet.


First I deleted the Wi-Fi network definition, and did not create a new one. Then I went to the device manager--Win Key+X, selected the Device Manager, and selected the wireless adapter. For my computer, that was the Intel Dual Band wireless adapter.


I right-clicked on the adapter, and selected uninstall, and in the dialog boxes choose to remove the driver from the computer. This gave me a clean slate to reinstall the driver from the Internet.


After the uninstall was successful, from the Device Manager Action Menu, I selected scan for new hardware, which popped up the Intel Dual Band wireless adapter again. I then right-clicked on the adapter, and selected update the driver, and selected update from the Internet. After the download was complete, I recreated my Wi-Fi network, and things worked again like a charm.


I am not sure why the wireless driver got corrupt in the first place, but it is good to know that the "Limited Wi-Fi Internet Connectivity" issue can be easily fixed.

Kindle Paperwhite

I have always been allergic to buying specialized electronic devices that do only one thing, such as the Kindle, the iPod, and fitness trackers. Why buy these when technology evolves so fast that a multi-purpose device such as the phone or a smart watch can eventually do the same thing, but with the convenience of updates that fix bugs and add functionality? So, I was shocked when this weekend I made an impulse buy and got the newest Kindle Paperwhite—a special purpose device for reading eBooks. I was walking past the Amazon store in the mall and saw that the newest Kindle Paperwhites were marked down by $40 for the holidays. The device looked good in the display, so I went in to look at it closely. The Paperwhite is small and light, with a 6” screen that is backlit and waterproof.   The text was crisp and readable, and in the ambient light, it felt like I am reading a printed book. I was sold and bought it on the spot. At home I have struggled to put it down. The bo...

A paper a day keeps the doctor away: NoDB

In most database systems, the user defines the shape of the data that is stored and queried using concepts such as entities and relations. The database system takes care of translating that shape into physical storage, and managing its lifecycle. Most of the systems store data in the form of tuples, either in row format, or broken down into columns and stored in columnar format. The system also stores metadata associated with the data, that helps with speedy retrieval and processing. Defining the shape of the data a priori, and transforming it from the raw or ingestion format to the storage format is a cost that database systems incur to make queries faster. What if we can have fast queries without incurring that initial cost? In the paper " NoDB: Efficient Query Execution on Raw Data Files ", the authors examine that question, and advocate a system (NoDB) that answers it. The authors start with the motivation for such a system. With the recent explosion of data...

A paper a day keeps the dr away: Dapper a Large-Scale Distributed Systems Tracing Infrastructure

Modern Internet scale applications are a challenge to monitor and diagnose. The applications are usually comprised of complex distributed systems that are built by multiple teams, sometimes using different languages and technologies. When one component fails or misbehaves, it becomes a nightmare to figure out what went wrong and where. Monitoring and tracing systems aim to make that problem a bit more tractable, and Dapper, a system by Google for large scale distributed systems tracing is one such system. The paper starts by setting the context for Dapper through the use of a real service: "universal search". In universal search, the user types in a query that gets federated to multiple search backends such as web search, image search, local search, video search, news search, as well as advertising systems to display ads. The results are then combined and presented back to the user. Thousands of machines could be involved in returning that result, and any poor p...
