TP-Link WR-1043ND Review

I bought the TP-Link WR-1043ND Ultimate Wireless N Gigabit Router since my supercharged buffalo suffered from a heart attack and died.

Guess why TP-Link calls it the Ultimate model?

Exterior wise, the TP-Link resembles the look of all its other wireless devices in the family.  It looks pretty good to me but I don’t really care because I don’t stare at the router at all.

The front panel has green/yellow LED lights to show the status of its POWER, SYSTEM, WLAN, ETH 1, 2, 3, 4 WAN, USB and QSS status. It goes *blink blink blink* till you get seizures. haha.

A side view of the router. Did you notice that there are NO vents at all on the top? The vents were situated at the sides and the bottom of the router. I don’t get why it was done like this but wouldn’t it cause the hot air to get trapped longer in the case? I’m using this router the other way round where the top faces the floor and the vents are at the top. You could easily drill a 12cm 90cfm fan on the top of the case and solve the problem too. [fan mod]

RP-SMA antennas – The router comes with 3 antennas to enable MIMO wireless N connections

Power jack – Common sense

Reset button – Common sense again

USB port – This enables the router to function as a NAS (Network Attached Storage). You can plug in any flash drive or hard disk drive into it. This port also allows the 3G modem to be plugged in and it will pull the WAN connection off the USB port.

WAN port – Your internet connection goes here.

Gigabit ports – These ports runs at 1Gbps

The router comes with a TP-Link firmware but there is a DD-WRT build for it. I did not do any testing on the original firmware as I flashed it to DD-WRT the moment I started using it. However as this is a fairly new router, the firmware for this router is said to be unstable but currently I’ve been running it for 5days ++ without any hiccups.

Lots of things to play with as it has a 8MB Flash Mem and 32MB ram.

You might be slightly disappointed on the wireless performance as it is no where near the performance of the Buffalo WHR-HP-54G (built in amplifier). Wireless performance is still good on this router, but if you are planning to do long range connections ( 2-3km links) with stock antennas, I wouldn’t recommend this router. Nevertheless, all the other hardware specifications pawn’s the Buffalo and costs cheaper than it! It really depends on the purpose of getting the router. Another good choice is the Asus RT N-16 but the cost doubles.

Wireless “Repeater” mode is not available on routers which run on Atheros processors so you would have to do this to get the repeating function working in DD-WRT. (This should work on all Atheros based routers). “Repeater” modes are only available on Broadcom devices.

1. Set the ath0 as Client mode

2. Create a Virtual AP

3. You’re done!

The TP-Link WR-1043ND is a really awesome device considering its low price tag . I bought mine for RM160 and you can’t even get anything near these specifications from other brands with this price. Good job TP-Link.

So how well does this router perform? I’d give it a 4.3 out of 5 star rating.

Sony Ericsson Naite (J105i)

w00t last post for the month.

It has been a real busy month and next month would be even busier. Oh damn I’m lovin’ it =).A couple of months ago I purchased some 500MB a month broadband from Maxis (here) and well, I did not have any phone to use it with! 2 months passed and finally I managed to collect enough money to proceed with the purchase of a used,  second phone to use the data plan with.

Here it is!  The Sony Ericsson Naite. I didn’t wanted to get Sony Ericsson again, argh.. but then the price was simply too wallet friendly.

This phone doesn’t come with much stuff though, only HSDPA, 2Mpix camera, 2.2″ 320×240 256k TFT screen, microSD card slot and those basic/standard stuff that you’ll get from most Sony Ericsson phones. The thing with this phone is that it was developed under the GreenHeart concept whereby the phone was designed to reduce the overall impact on the environment. Benefit is, the charger automatically reduces its power consumption when the phone is not plugged in thus saving some electricity.

Bad thing is, the back-plate of the phone looked pretty good but if you were to pry open the phone , the plastic feels cheap and easily breakable.

Software aspect, the phone feels slightly sluggish like most 320×240 Sony Ericsson phones. Uses the same firmware as the C510. Surprisingly, it supports the Microsoft Exchange protocol so syncing emails, contacts and tasks was absolute fun.

Size – Thickness.

The Sony Ericsson Xperia X1[left] and  Sony Ericsson J105i (Naite) [right]

Verdict:

Phone feels really good when it costs RM100 including postage.

It comes with Thorus warranty (4mths remaining).

Battery life – So far it has been running for 4days and still at 20%

Bad: Its a 2nd hand unit.

Dell Studio 15 Showcase

It has been many years since I got hold of a Dell notebook. The one with me now is currently turning 8 this year and today I got hold of this red Dell Studio 15. W00t call me jakun or whatever, but I think the bag looks quite good. Though the bag capacity is rather limited, it can still hold a couple of things like your external drives and stuff in it and still look slim.

Here’s the Dell’s version of Targus notebook bag.

This thing looks gorgeous from the outside..

The inside, hmm.. not so good. Looks rather plain with the grey/silver finish. The keyboard was slightly on the “bendable” side because during typing you could actually see the whole keyboard moving slightly.

Call me jakun again but it look me a minute to figure out where the power on button was! HAHA!

As usual, the Dell Studio LED screen did not fail to impress me. Colors were vibrant and text was sharp. The blacks weren’t black enough though..

At a certain angle I could see some line scanning going on, I’m not sure whether this is a problem with the screen or it is meant to be like that. Anyway it is only visible if you really stare at the screen properly. Will check it out once the setup is complete.

Again! the 90w power adaptor has been trimed down to a size thinner than my phone. Nice one. It runs pretty hot though. The notebook itself runs quite hot during idle times too.

Overall, the Dell Studio 15 is a quite a powerful machine here. Equipped with the Core i5 2.4ghz , 4gb DDR3 ram, 1GB ATi HD5740, 500GB hdd, this notebook is perfect for watching my TVB dramas!! AHHAHA.

Special thanks to Ivy and Eddy for letting me molest their very new toy. I couldn’t resist myself from snapping photos of your notebook. It was simply a natural poser.

Maxis Broadband (Hotlink) iPhone 500mb

Heck, I’ve got myself a 500MB x 12 months broadband subscription with my recent “purchase” of an iPhone from Maxis. It was a really good decent deal since 500MB a month is rather sufficient for me (I’m gonna use this solely for phone connectivity) rather than having to pay more for additional bandwidth but not being able to completely utilize the quota given.

Don’t ask me how I got it but its legal. haha. I know some of you know how this thing works.

Okay so called HSDPA eh? I did a speed test on the phone itself when I received the sms. only 380kbps. Ok never mind, then I tethered the connection to the pc next to me and managed to get a spike of 3mbps+ and then it dropped to 800kbps. Arghh. Since it wasn’t my pc I did not do any diagnostics on what had caused the speed to drop.

Went back and tested the connection again. Alright looks like I’ve found the reason for the drop in speed.

Pings were averaging at around 50ms during idle time and once something huge starts downloading, it spikes up to 3000ms and eventually times out. Full bars on my signal meter did not seem to help either. However moving the phone to a few “strategic” locations seemed to help maintain the connection for a little bit longer. (guess a good feng shui master is needed then). I did the speed test a couple of times and they were no where near the advertised 7.2mbps speed. The highest was around 4mbps only. Just a wild guess, perhaps the HSDPA network at my area is too congested? Upload speeds did not go above 60kbps but that didn’t really matter.

Here’s one of the screen-shot that I remembered to copy the link down.

Hey Ai Yean, did you just say that your Maxis broadband subscription was running slow? Mine’s even slower!

Windows Live Wave 4

Windows Live Wave 4.

Microsoft have been doing their job recently and here’s a new “preview” of their new Windows Live Wave 4. Supposedly “redesigned, reinvented, re-everything.. LOL. Here’s the video of their new thing. Microsoft here, microsoft there.. blablabla. Oh yea, did I hear the word, iPhone? =P

Among the new features are :

Badges

Show your affiliation with an organization or social cause and have this show up next to your name when it fans out to your friends.

Games

More games in Messenger let you play with your friends, earn achievements and brag about your wins.

Video message

When your friends are offline, leave them a video message, similar to a voicemail but as a quick video that will be waiting for them when they sign in.

Integration of Bing results

Integration of Bing search results makes it easier to add photos and videos from across the web without having to leave the conversation window.

High-definition video chat

Meaningful conversations are enhanced by allowing you to see and hear your friends. The new Messenger now provides high-definition video chat, helping you experience video chats so you can share photos while chatting and see your friends’ reactions in real time and in full screen.

Tabbed conversations

You can manage all your chats in one location so you can juggle multiple conversations in one place rather than having multiple windows popping up.

and many more..

About the High Definition Videocall, we can’t even get smooth videocalls on standard definition here in Malaysia and now HD, oh you have to be joking..

Anyway, there are plenty of “beta” versions up on megaupload/rapidshare if you wanna check it out but I’ll just wait for the official release from Microsoft. We’ll see then whether I’ll have to put my status on “Appear Offline” more often, or rather not.

DiGi EDGE Signal Awesomeness

I woke up just morning to find my phone dead. It was still on before I went to bed but looks like it was lazy and went to sleep too. Or rather not. It was spending the whole night SEARCHING for DiGi’s EDGE signal and *probably* after  a couple of hours, it got tired then decided to stop searching and take a nap. (it saves battery too).

A quick bootup on the phone shows that there is no service available so ZOMG what’s wrong with the phone. Enabled HSDPA and it worked! . SCEW DIGI SCEW DIGI!! My battery was at ~70% before I went to bed!

Fired up my Firefox web browser and loaded the DiGi customer support and here it is..

(10:32:29 am)  DiGi CS:  Hi, welcome to D’Chat. My Name is NORTISHA. How may I assist you?
(10:32:51 am)  Anonymous: Hello what is wrong with the digi line? I wasn’t able to get any signal without 3G connection since last night
(10:33:00 am)  Anonymous:  now i have to enable 3g on my phone to get the signal
(10:33:02 am)  Anonymous:  EDGE does not work
(10:33:40 am)  DiGi CS:  We apologize for the unplanned outage. Rest assured that we do our best to get it resolved immediately if it happens again
(10:34:11 am)  Anonymous:  this outage is throughout Malaysia?
(10:36:32 am)  DiGi CS:  It’s intermittent
(10:36:45 am)  DiGi CS:  Almost all part of Malaysia
(10:37:00 am)  Anonymous:  alright
(10:37:08 am)  Anonymous:  so phones without 3g would be disrupted?
(10:38:06 am)  DiGi CS:  Yes apparently
(10:38:31 am)  Anonymous:  alright that is so cool.

So there you have it! Cellphones without 3G shall not work today on DiGi’s fu*ked up network.

ZAGG discount code April 2010

ZAGG is popular for its line of invisibleSHIELD and many other items which came after that. Although there are many.. yes many many other gadget protecting skins out there which are of the same quality and CHEAPER,  here’s a discount coupon/voucher/code for you if you insist on getting one. Discount code is valid till 31st April 2010.

They gave me this code and I’ve nothing to buy from them, so I’ll just pass it on then =).

The discount code is valid for a 20% discount store wide :  p8b1w4n

I’m currently looking for a cheap but good skin to replace my worn-out Sansa’s protector though

E5300 in the house!

I’m replacing my E5200 with an all new E5300! Okay okay, this doesn’t sound much but then why E5300? Reng Kwan’s getting 3 new rigs for his company and why not swap my E5200 for this E5300? The newer 100mhz faster E5300 processors have Intel’s VT-x technology in it and with that I’d be able to do more virtualization stuff or even run parallels on my hackintosh. The older E5200 does not support VT-x. Prasys.. I’m coming to your way soon. LOL. 

As expected, this E5300 is indeed a good overclock-er surpassing my E5200′s overclocked speed. The E5200 was a good overclock-er too but perhaps I didn’t manage to get the good performing ones with mine overclocked to 3.1ghz only. The E5300 running now could clock speeds of 3.75ghz before the maximum operating temperature became an issue. The stock heatsink – fan wasn’t sufficient to dissipate the huge amount of heat fast enough. Have a look at the stock heatsink fan of the E5300 and the stock heatsink fan of the Pentium 4 HT 3.06ghz. Almost double the thickness.

Alright, I’m just waiting for the thermal paste from Reng Kwan as he bought a Q8300 for himself. It pwns all the chips here even before overclocking .. ==’  But anywaysssssss, I’m glad that this chip outperforms the Intel Core i3 chips which costs 2~2.5x more. hahaha.

Processor showdown =)

Samsung T400 dissected-Part2 (Surgery)

Few weeks ago I wrote a post regarding the Samsung T400 dissected and the screen was brought back to life. However as posted there, the keypad of the phone was slightly cranky and had to be modified a little. Well modifications don’t really match the quality of a real working unit.. The keys were still a little hard to press and each key would require different amount of pressure to make the input work.

Oh anyway, let’s get to the point. I managed to get the replacement unit for this phone at a local flea market. The phone was pretty much screwed up with its flipping parts broken into 2. LOL. The unit was from Vietnam though.. (says the firmware when it was booted up).

Ahh, the two keypads together. Look at the hinge where the other phone broke. *ouch*.


(“new” and old)(rev 3.3 and rev 3.2)

The two mainboards together. The keypad of the phone was actually soldered on the main board of the phone so it would be a little messy if the keypad was replaced. Instead, the easier way was to simply swap the main boards and plug everything back in. The “new” board was a rev 3.3 board while the original one was rev 3.2 . Didn’t notice any difference in performance though. I accidentally broke the volume button ribbon during the brain transplant. Such a waste, no more volume control for the phone but then the other functions works good. If there’s a need for the volume control in the future, I shall perform another surgery to transplant the volume control ribbon from the working unit.

Now the phone is working great. Time to get another sim card and get it back to duty.

Total cost of repair: RM2.

Hackintosh on a $300 pc

Oh yeay! Finally, a real hackintosh Snow Leopard running on my $300 desktop pc.  QE/CI on the graphics card works perfectly here, we have sound, wifi, etc.  Performance wise? Between the 21.5″~ 27″ iMacs.  The real iMac’s costs $1199 (the cheapest). I’ll post up a guide on the installation soon.

My specs:

3.2ghz Core Duo (yeay!)
4gb 1066mhz ram
500gb 7200rpm hdd
512mb ATI HD4670 (256mb more!)
Cheapo USB Wifi
6 USB ports (yeay! we have more than the iMac)
Razer DeathAdder

A real iMac specs? here!
Well, in the screenshot it shows there 800mhz ram. Its actually running at 1066. Have to fix it..

Sound output is at 2 channels currently. Don’t intend to get 7.1 running unless I have the speakers..

and all I need now is an Apple Cinema Display… =P
