Change router ip to 192.168.11.1 and flash.


Nothing changes, tried both webgui and telnet flash.

Nop, you need a TFTP flash. Here is what you do. Change router ip to 192.168.11.1, set your network to 192.168.11.2, and rename the file root-Uimage to firmware.ram

Thanks for your message, but I configured dd-wrt now and it is working great, no decrease in performance, so there is no need to go back to Aceex firmware.

Good. Me too, I've just reverted back to dd-wrt and very happy with it!

Telnet command works well under v24-sp2(13968).

HankChen, do you work for Aceex? If so, can you tell me what the difference is in the newer NR22/Y firmware. I cannot see any information on Aceex homepage, not even the version number. The only thing I can see, is that the date changed on the ftp site.

Yes, I work for Aceex, as I know the firmware base on Ralink SDK 3.3.0.0.

@HankChen;
Thanks for your detailed post Wink
I have a question for your, in dd-wrt, TX Power is 71(default 71, range 1-254). What is the suggested TX Power for this router?

Sorry, I never study source code of dd-wrt.

@Hankchen

I was able to flasg dd-wrt on my NR22/Y, and it's good!! But since I would like to use "Xlink Kai", the feature seems doen't exist in std version. Dose it possible to flash kaid version or other version which contain it?

The technical product specification says that Transmit Power is 17±2 dBm. That means something between 50 and 79 milliwatts transmit power. The suggested default value for Aceex NR22/X would be 50.

17 dBm = 50 mW
18 dBm = 63 mW
19 dBm = 79 mW

17dbm is pretty much a standard value quoted by manufacturers for most routers but, if anyone cares, Ralink specs RT3052F at just 14dbm (that is about 25mw). See it @Google Cache.

This strikes a few questions,
- are the manufacturer claims accurate?
- are those numbers including or excluding any antenna gain?
- do the boards that claim other values have a built-in amplifier to achieve those numbers?
- most importantly, how to translate in those boards the real power output to the driver that just regulates the output of the RT3052F SoC?

Still, I must point out that oddly this product brief also appears to claim that RT3052F is capable of 2T3R, while other Ralink documents spec it at just 2T2R.
A little bit of consistency from Ralink would be nice.

Other makers specify their RT3052 based routers like the following.

802.11b = 19dBm@1~11Mbps
802.11g = 16dBm@6~54Mbps
802.11n = MCS0~15@>16dBm

Well, every manufacturer can quote their own power output value, since they may bundle the router with different antennas (a different gain will by consequence cause a different power output), they may have a built-in amplifier in the board (unlikely for most routers) or they may just be "over-spec'ing" their settings (like we can do with DD-WRT).

But I believe that isn't entirely the point here... If we are trying to set our own "baseline" for the power configuration of this SoC I think we should be aware of the other considerations, like how the SoC manufacturer spec'ed their own chip and how the actual power output may deviate from the value we input in the driver because of the above mentioned factors (antennas or amplifiers).

It's all about being informed and making informed compromises.
With that said, I really must say that the spec you last posted (16dbm@11g/n) has been the "holy-grail" for my WHR-G300N ever since I purchased it quite a few months ago (I don't recall if it has been a year already).

IMHO extensive SNR and bandwidth testing is the key to finding the right compromise, provided you aren't looking just for the distance. Just don't go crazy and then wonder why a chip that has been quoted by the manufacturer for 14dbm (that is ~25mw) may not work that well at things like 100mw or even the DD-WRT default of 71mw..
