Creative Sound Blaster Roar

Sudah lama pengen beli wireless speaker, baru kesampaian sekarang. Ditambah lagi dengan adanya SITEX 2014 di akhir tahun ini, banyak toko yang cuci gudang. Creative Sound Blaster Roar yang biasa di luar dihargai sekitar S$199, dijual S$348 untuk dua biji. Joinan dengan seorang teman, jadi total hanya sebesar S$174 yang saya keluarkan untuk wireless speaker yang terkenal value for money ini, ditambah dengan carrying pouch untuk travelling. Dengan harga segitu, untuk kualitas dan limpahnya fitur, Creative Sound Blaster Roar menjadi pilihan pertama dibanding merk-merk yang lebih terkenal semacan Bose, JBL, dan Jawbone.

Set an old router as wireless repeater

After successfully upgrade the firmware of an old Linksys WRT350N with powerfull DD-WRT, I tried to follow guidance from Lifehacker to set the router into a wireless repeater. It means that the router can communicate with the main router wirelessly.







1. Connect to the wireless and go to 192.168.1.1
2. In DD-WRT, go to "Wireless" tab, choose "Basic Settings", set the Wireless Mode as Repeater, enter the the SSID the wireless network from the main router (in my case: CRP_24)
3. Add new Virtual Interface (in my case: CRP_24_Repeater), then click "Save", do not click "Apply Settings"




















4. Go to "Wireless" tab, choose "Wireless Security"
5. For Physical Interface, put the Security Mode, WPA algorithms and key as same as the wireless network from the main router
6. For Virtual Interface,  put the Security Mode, WPA algorithms and key as we want (in my case, I made it same), then click "Save", do not click "Apply Settings"

















7. Go to "Security" tab, choose "Firewall", untick all tick boxes, disable the SPI Firewall, then click "Save", do not click "Apply Settings"

















8. Go to "Setup" tab, choose "Basic Settings", change the local IP address to make it different from the IP of primary router (in my case: 192.168.2.1), then click "Save", an now click "Apply Settings"



















9. The router will reset, wait until you can see the wireless connection from the repeater (in my case: CRP_24_Repeater), then connect to it.


























10. If everything is okay, you should be able to connect to both routers' GUI in the same time using different IP addresses

primary router: 192.168.1.1
wireless repeater: 192.168.2.1





















Now my old Linksys WRT350N is a wireless repeater for my ASUS RT-AC68U... :)

DD-WRT on Linksys WRT350N

Yesterday I bought used Linksys WRT350N wireless router for S$ 15 from Gumtree. Damn cheap... :))
And today I just successfully flashed a more powerful firmware from DD-WRT that allow the router to do more tasks as enterprise routers can do.

With DD-WRT firmware, I can use this old router not only as a hub or switch that required LAN cable to extend the internet coverage, but I can user this as a wireless repeater or wireless bridge that can extend the internet connection from the main router wirelessly.


  1. Download the firmware from http://dd-wrt.com/site/support/router-database
  2. See the instructions at http://dd-wrt.com/wiki/index.php/Linksys_WRT350N as reference
  3. Do a hard reset for 30 seconds.
  4. Go to Linksys default GUI on 192.168.1.1 
  5. Go to "Administration" then "Firmware Update"
  6. Browse the file (dd-wrt.v24_mini_generic.bin)
  7. Click "Upgrade" and wait until "Upgrade Successful"
  8. Power cycle the router and do a hard reset again for 30 seconds.
  9. Wait until you can access 192.168.1.1 again.
  10. Configure the router with DD-WRT firmware.

ASUS RT-AC68U


In SITEX 2013 yesterday, I bought ASUS RT-AC68U wireless router to replace my almost-6-year-old Linksys WRT54G that give many issues due to its weak radio signal and slow speed.

ASUS claimed its latest flagship router as the fastest wireless router yet. RT-AC68U uses Broadcom’s second-generation BCM4708A SoC, which features a dual-core ARM Cortex-A9 processor. Its RAM is 256MB. By using Broadcom chip, it means that this router will be supported by DD-WRT in the future. 

Right now, the router that I got is running on Firmware version 3.0.0.4.374_205 from ASUS.

BlackBerry Z10

The 2-year contract for my mobile phone service would be ended on Jun-13, but after 21 months I can have new contract service and get a new phone. I was comparing iPhone 5, Xperia Z, and BlackBerry Z10 to replace my iPhone 4. Because my father at Indonesia just started using BlackBerry one month before, I decided to pick the Z10 to allow me having better communication with him.

It is unusual for iPhone user moving to BlackBerry since iPhone is still the phone offers best experience for customer, in term of number of popular applications and simplicity. But after a couple weeks using Z10, I found that it has better user interface in BlackBerry 10 operating system. RIM has been working hard to develop the OS to compete with iOS and Andriod.

One other good think is BlackBerry Link. Compared to iTunes, BlackBerry Link is faster and simpler to manage my music, pictures, video, and documents at my new Blackberry Z10.

MacBook Air 13"

It has been more than 5 year since I bought my first personal notebook. Now that Compaq Presario machine is sickly. Due to its age, it has LCD problem, battery drop, and performance issue, it simply needs to be retired.

Anyway I can use my company notebook for personal things, but it is big, heavy, and not fast enough. So rather than having backache, I decided to buy a new one in this COMEX 2012. After considering all light, slim and fast ultrabooks from ASUS, Samsung, Dell, and HP, I decided to try something different. So I bought a MacBook Air 13" and I cannot be happier right now. In the design wise, it is in the different level, if not in the different world. In term of performance, it is very fast. Thanks to the efficiency of the Mac OS X.
