MSI RG60SE Wifi Router

Monday, November 12th, 2007

MSI RG60SE wireless router review.

I bought one for fun – just to see what is inside and to try to play whit it.

Price ~ 35 Euros

msi rg60se box

This picture may confuse You – this device has only one antenna on its back.

What is inside of the box – router, ac adapter and antenna, also two pages of printed documentation and a disk.

NO LAN cable! So You need to make or buy one to connect the router for first time configuration.

rg60se back

On the back side of the RG60SE router we have 4 port switch, WAN port, power in, reset button, rp-sma antenna.

ac adaptor

RG60SE Ac adapter – output 0.8A at 9V this is the ways better than dlink or linksys strange voltages.

And finally antenna – as I said reverse polarity sma – surprise was that this is at least 5dbi antenna – whit two metal tubes and a spring, if anyone need a dimensions I will post them.

Now the fun part – let see what we have inside !

According to the speed I suspected that this is atheros device but nobody can be sure until you open and see the board.

Here it is closer look – Atheros AR2318 soc chip, interesting because Atheros do not have this chip listed in their product line. They had AR2317 which is only 54Mb as speed and it is used in WRT54G 7-th version I thing.

Here is a link to the Atheros AR5007AP-G platform – AP61

The main difference between AR2317 and AR2318 should be only the speed this is often in their products.

Block diagram and reference board. RG60SE is very closer to the Atheros reference board.

Elpida S6416AHTA-75-E rg60se msi

RAM chip is a 64Mbit Elpida chip, model S6416AHTA-75-E – datasheet may be fount on the Elpida page : E0439E70_EOL.pdf

Another chip Marvell 88E6060 is used for the lan part. LinkStreet_88E6060.pdf


Last thing is the flash chip –Spansion FL016AIF, I am not sure but this should be the datasheet : s25fl016a_00_c2.pdf

So this is all about the RG60SE hardware, You can find a lot of similar devices around :

Linksys wrt54g ver.7 uses AR2317,

TP-link WR541G + uses AR2318,

So this is just a TP-Link router just neet to know which one???

Its 108mb wireless router so it must be TL-WR642G which have 3 hardware revisions.

Ver 3 has Intel flash so its defiantly not mine and it also support WDS function.

But this is for now – I still cant find LAN cable to connect to mine new router 🙂

T-link update firmwares

Update and screenshots of RG60SE UI soon 🙂

Dual-Band 2,4Ghz / 5Ghz Omni WIFI Antenna

Monday, October 15th, 2007


Here is the scans of inside – very thin pcb board is used.


Some time ago I needed some 5ghz antennas – this is the first thing that I bought.

Dual-band 11a/g 7/5dBi Indoor Omni Antenna from trendnet.

The papers says :

Frequency Range 802.11a: 4.9 ~ 5.875GHz
802.11b/g: 2.4 ~ 2.5GHz
Gain 802.11a:7dBi
VSWR 2.0:1
Polarization Linear, vertical
HPBW/ Horizontal 360°
HPBW/ Vertical 802.11a:25° 802.11b/g: 35°

The stupid thing is that on the site specification and in pdf data sheets was said that this antenna have VERTICAL polarization, but now I can see that omnidirectional pattern came whit horizontal polarization!

This may be the reason why I am not happy whit this wifi antenna and it is still laying on my desk.
I will test it again when I have some time.

The other small wifi antenna that I have from trendnet is working great – I have small 5ghz link whit it – these days maybe will scan ti too.

Omnidirecional WIFI Antenna 6dbi

Thursday, September 6th, 2007

This one is very interesting design. I was used something VERY similar before time and all that I remember is, that it defiantly WORK fine, but it is pain to tune this.

All pictures are from this page :

This antenna is combination from usual J Pole antenna and Franklin array antenna /AMOS antenna only onmidirectional /.

Gain of this omni antenna is around 6dbi, but you may add more by adding more sections. Double the sections to add 3dbis.


Dimensions :


And feeding point and tune stub :


Some suggestions :

First CHECK dimensions of Your antenna.

Second : Matching to the feed-line is archived by sliding the connection of the feedline back and forth along the stub until an SWR as close as possible to 1:1 is obtained.

Third : Try to add quarter-wave ground plane.

Four : You can bend the half wave section to a half circle to be able to use small diameter of plastic tube :
