Here are the pics for the above antenna mods.

Both WHR-G300N's have the same set of antennas.

I didn't take internal pics because they look exactly like slaveunit's pics above, except I had longer UFL -> RPSMA cable's and different antennas.

Just showing the pics of the different antennas mounted.

Pics aren't the greatest, but you'll get the idea.

From another client (my HTPC) I get the results shown below. The client has an airlink 150N pci card in it. I think it's chipset is 2860? I do have 2 directional +10dbi external antennas on that. This machine is one room over. So the signal is passing through one wall and about 15 feet. This is the card http://www.airlink101.com/products/awlh6070.php and here is the signal from that one. A bit of an overkill for now. But Ill move into a bigger house sometime or another. So I am hopefully prepared. This screenshot was not taken right after the connection. I know most connections start at 100% then drop down. It did sit there for quite some time.

Guys, what is the trick to open that router. I unscrewed 4 screws and was trying to separate it from each other but couldn't. I don't want to crack it. Is there any other screw or latch? Thanks

[DoesItMatter]

I split my 2 apart pretty easily, the front LED cover is sticky backed plastic.

Once you remove the 4 screws under the pads, you can just split it apart.

Easiest place to start the split is the 2 slots where the base plate fits in.

There are some VERY slim tabs inside, that also help the covers clip together.

These are made to be broken once you crack the router open.
I.e. a quick way for Buffalo to tell if you've already opened the router.

Once you do the bottom (base plate slots), back (near the Lan ports), and top,
you can work out the front - its just sticky plastic for LED cover.

Just keep working the case open with a butter-knife or small thin blade flat-point screwdriver.

A question.
For the same price ( 9€ )what would you get:

2x 12 dbi Antenna with Base-stand and 3mt of cables (that you can place far from the access point)

or

2x 16dBi Antenna without base and without cable (that you must put on the Acess point?

I mean what is more important, the pure dBi numbers or the space between antennas?

[DoesItMatter]

Hmm... I'm not sure on that. I know there would be signal loss with the extra length of cable.

So instead of 12dbi, you might be getting like 9 or 10dbi instead.

As far as the distance between, I thought for the 300mbps mode,
1 antenna is output, 1 antenna is input (on 2.4 GHZ)?

I guess the only thing to do is actually try it.

Thread to see what the Internal Antennas look like.

[AMG]

Hey DoesItMatter, where did you get those antennae from? I wonder if I will see a real difference using some huge HP antennae compared to the standard external ones that appear on stuff like WRT54G and other routers?

[DoesItMatter]

E-bay for all my parts.

I'm in the USA, but purchased Antennas from Australia, and the ufl pigtails from China.

It took about 3 weeks for each, but it was worth the wait because it was so cheap!

I got the pigtails and antennas for about 25% of what I would have
paid locally or if I had bought from USA vendors.

[TheLostSwede]

Well, after reading this I figured I'd give it a go myself.
As I'm not using any Buffalo AOSS devices I popped out the AOSS button and fitted the SMA plug in the hole. It's a bit of a gap, but it fitted nicely, although I had to remove some plastic inside the router to fit the SMA plug through the hole. I only added one 5dBi antenna, but it still seem to have improved the general signal quality, although I'm still having problems with my Xbox 360 upstairs that doesn't seem to want to give me more than barely a single bar...
It's a bit of a pain to crack this router open, but not a hard product to mod otherwise. The internal antennas are tiny and doesn't look like they offer much in range.

[sodalink]

After seeing the mod for the buffalo G300n router I wanted to do it myself. However I don't know much about cabling and every place I've looked at (ebay, google, etc) I see UFL to RP SMA really expensive. The cheapest I've found is 7 dollars each. I already paid like 8 for 2 antennas.

Also could it be possible to reuse the other cables and some how attach them to the antennas?

[TheLostSwede]

Well, I bought mine locally (last one in the shop) and it was about $5, so yeah, I guess they're quite expensive, at least compared to the antennas. It's unlikely that you can re-use the internal antennas, unless you're really good at soldering and hard wire the attachments into your antennas somehow.

Also, one note if anyone is considering my approach to use a single antenna, make sure you attach it to the connector that reads con3, as this seems to have a much bigger effect on the transmission performance of the router.


Con3 is the one at the middle of the PCB

I have seen the threads on packet loss. What version of firmware have you guys found works best for stability?

[sodalink]

Does anybody has this router bridged to another one? Right now I have it appart since I haven't bought the cables for the antennas. But, once I get them I want to somehow bridge this router which has DD-WRT firmware and a Linksys WRT160n. I intend the Linksys to be the primary one unless I upgrade firmware to DD-WRT. I think I have version 1? it says firmware 1.02.

if someone does can you post pics of settings?

[tuxgeek]

I have had better success using a linksys or generic style router as the client bridge(s), and using the WHR-G300N as the AP
