Any specific details on these hacks? From your first few post you only mentioned things like power supply modification (caps on the card, bigger input PSU, PSU caps) and shielding. Those of course would decrease noise and increase stability, but not increase the gain of the amplifier stage or the input sensitivity.
And additional details (preferably as technical as possible, EE in training), would be appreciated.
Page 8 and on
the jumper on the regualtor puts the rf amp a full Vcc well as full as the main power regulator will do.
its all thair just read....
buy turning up the pupply voltage from 4.72v to 5.04v the rf amp will let you do more rf power out.

That's for the WHR-HP-G54 isnt it? I was wondering about the WRT300N you did the initial work on. Is there a second stage regulator on the PCMCIA card that you bypassed or something?
yes that is for the WHR-HP-G54
the mods for the wrt300n well its alot of work
i never posted them cause thay are not just "simple" mods and did not want people to destroy there router trying to complete them.
and it was just a test router and now is back to "normal" well Most of it is with a wpc600n in it .
just waiting for Non broken firmware to come out.

I'm about to graduate with a degree in electrical engineering, so it sounds like fun to me :wink:
Not to mention the experience can't be a BAD thing seeing as we install a lot of microwave equipment at work. Destroying things is just part of learning as far as I'm concerned.

Interesting note...
Been playing with signals lately...optimal settings...cantenna...WRT54GS and Buffalo routers and noticed that depending on your laptop wireless card
the signal strength and quality changes. I have a Linksys WPC54GS PCMCIA card in my laptop and the signal is very choppy. Using an HP laptop with a built in wireless card the signal is smooth and a lot stronger. Didn't look at the HP wireless but it is BC. Makes sense I guess but I think a lot of people may be missing this point when trying to optimize or trouble shoot crappy connections?

but try to get a stable and clean signal on Whatever card you use.
I have seen this alot myself but can make it good and stable on
Intel , dell , Broadcom , Atheros cards.

Okay. Do you need it in hand signals and picto-grams? Or can you figure it out by reading my post a few times? I try not to grovel to the level of misspellings and private attacks in a public forum.
* If you want to hard-wire an antenna pigtail directly to the 'source' of the signal, fine.
* If you want to use a simple part which gives a nice finished product, that's okay too.
User Radioman's solution for adding a second antenna, which he compares with the other mod as 'wrong', will work and give a more stable, stronger signal. Otherwise, those traces on the buffalo board are very long. The LINX Technologies part CONREVSMAxxx gives a nicer finished product and less work. If you want to go the 'radioman route', then it's necessary to put the Buffalo in an entirely different box as radioman has. The case it comes in is just shit for those comprehensive mods he is on about.
I'll post some signal inSIDDer readings as soon as I can make the time; it's not a high priority now.
you dont NEED to change the case to do the antenna mod the proper way its just that the 2 antennas will be close to eatch other .
Or you can use the antenna connectors for Ext. antennas.
I did a case change cause the buff. did not come with a stand , the case was in Poor shape , amd for better cooling.
as the 300n case has alot more room in it
It is in like new condition
and will stand Vert.
oh yes it looks Better

WHR-HP-G54 with the multi-voltage 5v 2.6 amp power supply pictured earlier.
In response, magnetic bases with a 1.5 meter cable ending in an RP-SMA connector are used. 9db internal antennas are weatherized with heat-shrink tubing on their two joints and the connection to the magnetic base.
Was wondering how much you believe the signal can be turned up in the mw setting until the output is balanced with the receive? Had settled on 30mw boardflags 3xxx when using the same setup as a client radio, connecting to free WLAN while waiting for an Internet connection to be installed or activated. Any more than 30mw did not seem to make a difference in performance as a client or AP. You have written outrageous mw settings do make a difference. The radio is installed with one antenna up, one down, on a boom 1 meter out from the edge of the building, so the omni's are direct line-of-site north and south on the street below. 3rd floor european old construction, 10ft ceilings inside. 4th floor if you are counting the ground floor as floor 1.

Enjoy the "toy"
Radioman...
What is the C11 chip on the flip side of the fuse? Will it fall off when the fuse is removed? I think I'm gonna take the router into an electronics shop and have them do the soldering...sooooo smallll can't see em...
squibt
lol
no it will not
Hey Radioman...
Got my Buffalo power mod done. Took the board into a radio shop and had them solder the wire...what a perfect job they did...
Re-assembled the router and booted it up and set the tx to 31 and it burned a hole in my study door!
Backed it off to 28 mW. Really just looking for a super stable signal as you pointed out upping the amps would do.
Question...can I use any 5v power supply up to 5 amps? I have a 3 amp one now.

It doesn't matter how many amps it is. The router unit is only going to take as many as it needs to use.
Imagine the quality of the power is much more important. Those power supplies which can deliver a smooth and consistent 5v under varying loads are better than cheaper models which simply deliver more amperage.

Thanx sdoboze,
Makes sense. What I am looking for is a strong high quality signal.
Radioman...you said you have WRT54G routers you are using with a better power supply....I have a WRT54G Ver 2.2 and GS Ver 1 and both have 12v 1000mA ps. What ps can I use on these boxes to better the quality?....
