depending on your client adapter this is normal.
how does 802.11n and 802.11ac work
in 40 mhz mode 2 channels are used.
the main control channel and the side channel often named as "lower" or "upper"
in that way its possible that 40 mhz and 20 mhz client are able to connect. the side channel is only used by 40 mhz capable devices and the control channel is used by all clients.
in 80 mhz 802.11ac mode it gets more crazy.
now we have 3 side channels. i could explain it, but you will already know what i mean. the lower lower, upper upper, lower upper, upper lower thing. and if your client adapter is not capable of detecting this (or your wireless scanner). you will see 2 or 4 networks. _________________ "So you tried to use the computer and it started smoking?

quick and dirty. should use the mac addresses as configured by asus and does not go the dd-wrt standard way. should fix the issue for cable modem users. (why isp's are still using mac filtering. this is the most stupid invention without benefits. it just makes troubles)

Anybody having problems with static leases? iPod will connect but never gets the static lease set. My laptop connects to wired, 2.4 and 5GHz and takes forever to get the IP set in static leases. But does not populate the DHCP list. Once both devices are removed from the static lease list they properly acquire IP's frpm the DHCP pool.
i took the code from asus. the formula you show is not the formula asus is using and it works also only if the wireless driver has been modified which isnt possible for the most users since they dont have the source codes unlike me
Then Asus is using different formulas in different places, because I definitely took this formula from the temperature monitoring webpage straight from their GPL archive.
Possible that it only works with their own driver, but I find it odd that your temperature would be so high, considering the CFE by default will throttle when temperature hits around 80C (I forgot the exact value).

Any suggestions?
the you have a typo in your static lease definition. maybe a host name which violates the standard. this will result in a non working dhcp _________________ "So you tried to use the computer and it started smoking?

then look again into your gpl archive. there are 2 places. within the webgui they simply just show the returning value. at the fan control daemon a average of 2.4 and 5 ghz interface is build.
in basic scheeme. 24iftemp + 5iftemp / 2
but its a little bit more complex since asus does a moving average by:
24value = (24value * 4 + new24value) / 5;
same for 5 ghz.
but there is no offset of 20 or something like that, your formula is wrong at 100%
take a look at rc/phy_tempsense.c for the moving average. the other location simply just uses the return value of the driver. but both code pieces indicated that the returned value is the temperature itself _________________ "So you tried to use the computer and it started smoking?

Is there a trick to flashing the file? I have tried everything, and end up with the same boot loop for my result. My device hardware version is A2. I set my static IP to 192.168.1.2 before proceeding, and even used 192.168.1.7 as someone else had done a few pages back. I attempted each of the following ways at least three times in a row.
I have attempted to flash from web gui after a factory reset in IE/chrome/Mozilla in windows 7 x64 and XP x86, and also chrome/Mozilla in Ubuntu with the same outcome of boot loop.
I also attempted to flash using tftp after putting the device into recovery mode, I did this with windows 7 x64, xp x86, and ubuntu with the same boot loop result.
I attempted to flash the file using Asus’s firmware restoration utility under windows 7 x64 and xp x86, with the same boot loop result.
I also attempted to flash the file from the recovery mode page with IE/Chrome/Mozilla in windows 7 x64 and xp x86, and also chrome/Mozilla in Ubuntu with the same outcome of boot loop.
I have no problem flashing back to stock using the firmware restoration utility, and the latest stock firmware.
I bought two ac66u at amazon. one of them is flashing without problem. with the second one I have the same issue. I have tried the same procedure also without succes.[/img]

This is on what I based my formula, from Advanced_PerformanceTuning_Content.asp:

Can you post a pic of the sticker?

What makes you think it's a vA2?
Here is the pic of the sticker, it says right on the sticker H/W ver. A2. I own two of these routers, both purchased at the same time from newegg, and both of them say H/W ver. A2 on them.

as far as for me and GMPOWER loading dd wrt on ac66u through GUI and tftp has failed, I would like to ask our gurus if there is another method to load this firmware?
Are we doing something wrong or it can be a hardware-software compatibility problem?
quick and dirty. should use the mac addresses as configured by asus and does not go the dd-wrt standard way. should fix the issue for cable modem users. (why isp's are still using mac filtering. this is the most stupid invention without benefits. it just makes troubles)
personally I like mac filtering...
Anyway, how is this test version working?
do it requires a 30-30-30 reset? or just a restore to factory and then flash from GUI?
