So all you have done to your router to get that clean consistent signal is that power supply?

Eko took down his 12367 test build for the 610N Confused Probably didn't want some idiot loading it thinking it was for some other router. Then we'd having people saying "Oh my gosh my router is bricked!" Shocked

lol no
alot of other mods to the radio.
but i would start with a good power supply .

I think the reason he took it down was because it was a specific test build. It was just meant to see if the few changes to the 610N specific code would solve the reboot issue. Since it did not, no need to keep it available.

The NEWD2 12367 is still available to download in this thread.

Either way, the 610N build of 12360 is running superbly on my 600N.

Exclamation I was able to finally get the radio tx power working on my wrt310n. Frame Burst set to enable was causing it to work improperly. Disabling Frame Burst solved the problem and I was able to see the SNR changes as I changed the tx power.


Did you need to use the NEWD2 firmware? OR just the standard firmware? Frame Burst is disabled by default, I just checked, so unfortunately it doesn't help tx output for the WRT300N.

I am using std NEWD 12360. I have always enabled Frame Burst as it increased my throuput and upload speeds. That was the only variable I had not tried to get the Tx Power to change.

Just an update. I've had WRT610N version of 12360 up and running on my WRT600N for 2 days now, no issues.

Tested my WRT610N, 12360 mega build.

1 pict:

a) Started with both radios 50 mW
b) wl0 goes 50mW -> 5 mW, signal up instead of down. wl1 signal insted being stedy, after 10 sec. goes up to. No actual change to wl1 power.
c) wl0 goes 5mW -> 10 mW, now radio reacts as it should, signal lower than it was at 50 mW. wl1 stays higher.
d) wl1 goes 50 mW -> 10 mW, more or less normal behavior, just signal drops not enought, stays close to level at 50 mW, wl0 steady.
c) wl1 goes 10 -> 5 mW, signal drops a little more. wl0 stable.

2 pict:
While painting pict1, monitoring continues. wl1 stable, wl0 with spikes. wl0 was 10 mW, wl1 was 5 mW, distance about 4 meters.

Final remarks (my oppinion) :
Power changing via web GUI on WRT610N 12360 mega woks.
wl0 dont like settings below 10 mW and signal tends to fluctuate a bit.

wl0 is the 2.4Ghz radio right? I noticed that power seems to fluctuate on my WRT300N similarly, but I see no correlation to power setting and output. Going from 70 to 28 may cause the power to go up, but then going to 56 causes it to go down.

Hmmmmmmm
50 Aint 50mW
Arrow 50 is 50% of the transmitters output
the wrt610n
"B" Mode is 16dbm = 33mW
"G" Mode is 13dbm = 14mW
"A" Mode is 12dbm = 13mW
"N" Mode is 8 to 11dbm = 7 to 12.5mW

"N" Mode is 8 to 11dbm = 7 to 12.5Mw


So, is that for all of the routers? Because as I was looking in the help file, it states that:

TX Power
This value ranges from 1 - 251 mw, default value is 28mw. A safe increase of up to 70 would be suitable for most users. Higher power settings are not recommended for users due to excess heat generated by the radio chipset, which can affect the life of the router.

So, am I to assume now that it's a % base?

It still doesn't make a difference to what number I put in. 2 or 98, both show similar signal strength.

These are Just a >few Examples<

The Sige SE2520L
most of the Old wrt54g routers have the Sige SE2520L rf amp
and its MAX output is up to +20dBm
typical output power at 3.3V for WiFi = 100mW
and
For 2.4GHz cordless telephone applications, the
SE2520L produces +23dBm typical SATURATED output
power at 3.6V. = 200mW

http://www.sige.com/uploads/briefs/15-DST-01_SiGe_SE2520L_Brief_Rev_4p10_May-26-2009.pdf

The Sige SE2523BU
DSSS 2.4 GHz WLAN (IEEE802.11b)
OFDM 2.4 GHz WLAN (IEEE802.11g)
18.5 dBm, EVM = 3 %, 802.11g, OFDM 54 Mbps = lets just say 40mW
23 dBm, ACPR < -32 dBc, 802.11b = 200mW

http://www.sige.com/uploads/briefs/192-DST-01_SiGe_SE2523BU_Brief_Rev_1p3_May-26-2009.pdf

The Sige SE2527L
DSSS 2.4 GHz WLAN (IEEE802.11b) 25 dBm, ACPR < -32 dBc, 802.11b = 316mW
OFDM 2.4 GHz WLAN (IEEE802.11g) 21 dBm, EVM = 3 %, 802.11g, OFDM 54 Mbps = 125mW

http://www.sige.com/uploads/briefs/157-DST-01_SiGe_SE2527L_Brief_Rev_1p3_AP_May-26-2009.pdf

So if you go by the way thay started dd-wrt with the Old hardware as max is 251
the The Sige SE2527L in "B" mode @ 25dbm that is 316Mw would only do 251mW. Confused HMmmmmm


Thats just the SIGe Rf amp's there are others with More power.

see Eko shuld change this in the firmware to read From > 1 to 100% < this way it would be Proper for the NEW hardware of today.
that would end peoples confusion over the "251mW" Max power setting in dd-wrt
Yes you can get more power with dd-wrt but ONLY upto the hardware's Maximum.
Hence 1 to 100%

That honestly would be a good idea. Confused Shocked

if this rain EVER stops here in NY
im going to try for 1/2 mile with winamp radio Playing and see if i still can keep a 5mbps Minimum connection.
ill change out these 7dbi antennas for 3 16dbi antennas first.
Cool
