Key Reinstallation Attacks or KRACKS of WPA2 wireless

17/10/2017 Leave a comment

To be honest, I read about this yesterday. It is quote discerning because it involves millions of wireless networks all over the world. It does not lie in the password but rather in the in the way WPA2 is encrypted, a way that can be compromised. You can check out this website here. I am worried about this to be honest

SMC wireless dongle

03/08/2015 Leave a comment

I have had this old SMC wireless G dongle for the longest time. The model number is the SMC2862W-G and I bought it for my old Fujitsu laptop that was not endowed with wireless hardware. What that mean was when I travelled overseas or visited a place with wifi, I could not be connected. When I was cleaning out one of my old drawers today, I came across it again. I tried to make it work with my laptop running Windows 7 but for some reason, I could nt find the drivers for it. All they had were drivers up to Windows XP. I cannot remember when I bought this but I guess that it had to be about ten years ago. I know that it served me well. I have no more use for it so I will be throwing it away. Thanks SMC!

TP-LINK TL-WR740N wireless router

06/07/2013 Leave a comment

I bought this router the other day for a customer that wanted to set up a new office. She was looking for an inexpensive solution for the office, linking up a couple of computers, a printer and an NAS storage device. So I bought this one. It was a lot cheaper than the other offerings from Cisco, Aztech, Prolink and the rest. It does all the things needed to have Internet access without costing half the earth. One thing I like about it is that you can use the Gargoyle operating system in it. This thing has four 10/100Mbps LAN ports and for wireless, only one antenna. Features-wise, according to their website:

  • 150Mbps wireless data rates ideal for video streaming, online gaming and internet calling
  • Wireless security encryption easily at a push of QSS button
  • IP based bandwidth control allows administrators to determine how much bandwidth is allotted to each PC
  • WDS wireless bridge provides seamless bridging to expand your wireless network

Not too bad. Wireless on the cheap. And good quality too!

TP-LINK TL-WR702N nano router

20/02/2013 1 comment

The TL-WR702N is an ultra-compact router that’s similar to the TP-Link MR3020 3G router but it does not have a USB port for the attachment of a 3G/4G dongle. Its features are:

  • 150Mbps wireless data rates ideal for video streaming, online gaming and internet calling
  • Tiny – Ideal for home and travel use
  • Supports AP (default), Client, Router, Repeater and Bridge modes
  • Powered through a micro USB port by an external power adapter or USB connection to a computer

Its compact size makes it perfect for travelling, and you can even power it from a spare USB port on your computer or laptop. It utilises very little power, so you’re unlikely to drain your laptop’s battery.

Interesting this is. I had a friend who called me up just the other day to ask if there was a solution to her travel woes. Looks like the solution is right here!

Linksys WRT54G router

16/02/2013 2 comments

I have had this Linksys router for some time now. At one time, I had two homes. One was my mother’s place and one was my own home. My own home had a Linksys WRT54GC router, which performed admirably, from December 2007 till this day. This Linksys WRT54G router was at my mother’s place, replacing an old SMC wireless router that bit the dust after giving me many years of service. That SMC wireless router was one of the best I ever had and it was a shame that it bit the dust. I wanted to get a replacement SMC router but the newer ones did not appeal to me at all so I got this Linksys WRT54G router and I still use it to this day. Great router at a great price, except for the fact hat I have to reboot it every now and again. It has nothing to do with the router in case that is what you are thinking. It has to do with my telco StarHub which has one of the shittiest connections in Singapore. But then again, as I said, this is Singapore and all our telcos are shit. But I digress. get this router and you will never need to buy another router again. Linksys build great products. They may be owned by Cisco now but I still think these routers are great. They even provide you with a 4-port switch at the rear of this router!

********** EDITOR’S NOTE 19th May 2013 **********

I just upgraded the firmware of the router today. Its sad. The router kept hanging and needed a reboot frequently. It has something to do with my internet provider Starhub. They keep changing their WAN address and it causes havoc with the router. So I thought, just to make sure it is not my router that is causing the issues, I decided to upgrade the firmware. The last firmware provided by Cisco Linksys was one from 2009 so I am using tat. So far, so good, I will have to see how it goes with this. Hopefully, it should get rid of all the bugs causing it to hang

Shure SVX288/PG58

22/01/2013 Leave a comment

I was using this Shure SVX288 wireless microphone system at an event a few days ago and I must say that I was very impressed with its performance. very clear and crisp vocals and excellent from a distance of almost 30 meters. Unlike the single Shure wireless system I covered some time ago, this is a bigger unit with two microphones instead of one. I already have two AKG WMS 40 mics and they operate on one battery instead of two like these Shure wireless microphone systems. The good thing about these Shure wireless microphone systems is that they have XLR sockets on their receivers, unlike the 1/4″ TRS phone jacks on the AKGs. Here is a close-up of the rear of the unit:

As you can see, there is an XLR jack for balanced and a 1/4 phone jack for unbalanced. Looks pretty good. I might get it. Maybe in the future but for now, the AKG will have to do! They have served me well and I am very happy with them

Shure SLX4 and SM58 wireless microphone system

09/01/2013 Leave a comment

I used this microphone the other day at an event on New Year’s Eve. I was quite amazed at the sound of it and as you know, when you pay for Shure quality, you get awesome quality. I should know because I have always trusted Shure microphones, especially their legendary SM58 microphones. I liked this but the only bugbear about it was the fact that the transmitter in the wireless microphone used two AA batteries and they did not last very long. If I do get something like this, I may have to go the rechargeable route or spend a fortune on batteries. I had batteries running out on me twice in the night and it sure as hell was not funny. My AKG WMS 40 Mini can go for hours on a single alkaline AA battery, and it is cheaper too! In any case, here are the specs of this wireless microphone and receiver:


  • Frequency response tailored for vocals, with brightened midrange and bass Uniform cardioid pickup pattern isolates the main sound source and minimizes background noise
  • Pneumatic shock-mount system cuts down handling noise
  • Effective, built-in spherical wind and pop filter
  • Supplied with break-resistant stand adapter which rotates 180 degrees
  • Legendary Shure quality, ruggedness and reliability
  • Cardioid (unidirectional) dynamic
  • Frequency response: 50 to 15,000 Hz
  • Automatic Transmitter Setup
  • Backlit LCD with timeout feature

As for the receiver:

  • Automatic Frequency Selection
  • Automatic Transmitter Setup
  • 960 Selectable frequencies across 24 MHz bandwidth
  • Detachable 1/4 wave antennas
  • Microprocessor-controlled diversity
  • RF presence LED
  • 5-segment audio meter
  • Multi-function, backlit LCD
  • Low battery indicator
  • Frequency and power lockout
  • Rugged metal chassis
  • Volume control on rear of unit
  • 1/2 rack design
  • Furnished rack hardware
  • Non-slip bumpers for use out of rack
  • XLR and 1/4″ outputs

I will say one thing and that is the receiver gives me the option of using either an unbalanced 1/4″ phone jack or a balanced XLR output. My AKG only has a balanced 1/4″ TRS phone jack as the output but it works out very well and I have no complaints at all. Oh well. Maybe in the future, when my AKGs die out on me, I may make the move for this.
