I like my rebranded tp-link router – XTECH Router

NOTE: This post was updated on feb, 1, 2013

Today, i got a new Wireless Lite N router for JD20 (Around $28), and it works like a dream, in reality, the following is a sampleof the routers web GUI response headers

Server: TP-LINK Router
Connection: Keep-Alive
WWW-Authenticate: Basic realm="XTECH 150Mbps Wireless Lite-N Router WR771LN"

Some Hanania Investment Group seems to be responsible for this new XTECH Brand, and for this router, it is well worth the money.

The RJ45 eithernet cable mentioned on the outside as included is not included, but then again, why would i need 1 more eithernet cable.

This model seems to be the same as TP-WR741ND TP-WR840N (since the TP-WR741ND is the same but with a detachable antenna), and if you know what little endian, big endian, and a hex editor are, you may be able to put the “Open Sourced” TP-LINK software back on this hardware.

The reason you can not is that those routers check for file name when you upload, and only 3 people in the world know what the firmware file name requiered by this router to accept new firmware is. I am about to become the fourth to know and hopefully everyone else can come later, (FYI i dont know who the three people are, i just assumed there must be three people)

Anyway, i hope all other XTECH stuff are as good as this one

NOTE: The only reason you may want to have the TP-LINK firmware back on this router is that there is no mentioning of this router on xtechinternational.com and therefore i can not find a firmware upgrade, TP link will surely have the upgrades as soon as they are out though.

Naming the firmware update file:

Update, although this is a re-branded TP-Link, i switched my TP-Link to dd-wrt, i think i will switch this to open-wrt or dd-wrt and not to the original tp-link firmware, mind you, we still need to know what the existing firmware expects for a firmware name.

In a TP-LINK, the answer is simple, you download the file factory-to-ddwrt.bin from dd-wrt, then you rename the file to be identical to the update file from tp-link.com, namely wr740nv1_en_3_12_4_up(100910).bin , but for xtech (The re-brand), there is no update file, and therefore we don’t know the name of the acceptable update file.

So lets see the similarities, and see what options we have
tp-link TL-WR740N gets wr740nv1_en_3_12_4_up(100910).bin
X-Tech xt-wr771LN should get ?
wr740nv1_en_3_12_4_up(100910).bin (same: NO)
wr771nv1_en_3_12_4_up(100910).bin (NO)
wr771lnv1_en_3_12_4_up(100910).bin (NO)
xtwr740nv1_en_3_12_4_up(100910).bin (NO)
xt_wr740nv1_en_3_12_4_up(100910).bin (NO)
xt-wr740nv1_en_3_12_4_up(100910).bin (NO)
xt740nv1_en_3_12_4_up(100910).bin (NO)
xt_wr771lnv1_en_3_12_4_up(100910).bin
xtwr771lnv1_en_3_12_4_up(100910).bin
wr771lnv1_en_3_12_4_up(100910).bin

The router is probably an atheros chip router with a

HYNIX 933S C
HY5DU561622FTP-D43 RAM

If anyone wants some photos, i can post them here for you no problem

you can find this router almost everywhere, SmartBuy Carefour, and others are stacking piles of it.

Good Luck

S.M.A.R.T (SMART) data of hard drives under linux

The results of the commands on this post are Here

On windows, You can use speedfan, under linux you can read the smart data as follows

Use the smartctl command, but first you must install the package

apt-get install smartmontools

1- Checking for smart support, (All recent hard drives have it but you need to enable it in BIOS)

smartctl -i /dev/sdb

2- Enable reading it

smartctl -s on -d ata /dev/sdb

See it

smartctl -d ata -H /dev/sdb

Read more

smartctl -d ata -a /dev/sdb

Now some manufacturer specific smart atributes exist, you need to google them out, Also smart is not definitive, if S.M.A.R.T data says ok but there is a ticking noise in your hard drive, Don’t trust the hardware data, get backup.

Some hard drives like the Samsung Spinpoint come with extensive diagnostics software, My 3 2.5′ disks pass the test, pass the smart test, and tick when warm, i will let you know if it was the tick of death sometime soon
