discovered strange thing : when selected Regulatory Domain is Lithuania TX Power show 18dBm and user connect with speed : 150/135 rates and after some time drop to 65/65
Now tested : select United Stated and TX power show 12dBm and user connect with 150/150 rates and after 24 min not droping speed

wow! a progress! but not in the way we wanted o_O
this is getting worse with every firmware
even if nothing has been changed on this device within the wireless driver. not every problem you feel has its reason on the ap. sometimes client drivers are buggy too or not really 802.11n compliant. 65 mbit drop may also happen if you dont use your wireless. the tx / rx rate is calculated on best performance base. if wireless isnt used, it dropps down _________________ "So you tried to use the computer and it started smoking?

the hardware has its limits too. this should be considered. new zealand allows up to 30 dbm in 2.4 ghz, but that doesnt mean that your hardware does support such power levels _________________ "So you tried to use the computer and it started smoking?

BrainSlayerI guess the main problem not wrong selected Regulatory Domain, but different TX Power. Now when it is 12 dBM wireless connection show 150/150 and not droping to 65/65. I tried when tx power was 18 speed changed to 65/65 and even wireless is active the speed don't change, when selected regional united state and dbm is 12 the speed when incantive change to 150/105 and when is active imeaditly change to 150/150. The problem I guess is solved

usually the problem is the signal quality here. too strong signals might also have negative effects. especially for 802.11n, where alot of performance is made with multiple paths (reflections)
150 mbit simply says ht20 mode + 2 chains. it seems your switched back to single chain mode which disables the multiple path capabilities since the rate control driver had too much errors in 2 chain mode. usually this was caused by too high output gain. _________________ "So you tried to use the computer and it started smoking?

Arh. That is a question i need an answer from expert.
Now back to the question, you mention multiple paths (reflections), i had an argument about wireless signal rely on reflections, however someone told me i had no idea of physics and Wireless Network @ 2.4Ghz will go through most materials apart from concrete and metals, and therefore its best signal strength is always its Direct Path. My experience has told me otherwise.
Do wireless signal reflect on all materials? Not that it is 100% reflected, but surely some does get reflected right? And therefore best path is != to direct path? Right?[/i]
swap function finally come into this build, thanks BrainSlayer.
however, still have the web gui crush issue when mount usb disk on the start up command.
and all others going well on G300NH so far.
Hope could fix this issue on next builds.
BTW,14929 have no this issue, and since 15xxx,all have this issue.

Are you sure that the optware libraries that you are using and exporting pth to is compatible with the new kernel?
Test with a script that only mounts the disks. _________________ Kernel panic: Aiee, killing interrupt handler!
any ieads on the changes?
