wrt54gx4 auto channel quirks in 1.00.15 firmware

    just updated my wrt54gx4 to the new 1.00.15 firmware and have some questions about the auto channel selection / ACE functions.

    These were turned on by default in the previous version, and are now are turned off. Linksys like most other vendors always defaults to channel 6, and i haven't noticed the channel changing automatically, so i suspect this function like several others doesn't work as advertised with this unit.

    here is the interesting part though. if i change to a manual channel, and don't use the ACE function (basic wireless tab) or auto channel from the advanced wireless tab, connection quality and speed drops.

    has anyone else seen this behavior?

    ACE adds an adjacent channel and increases throughput and connection speed. If you use only one change the connect speed not throughput is 126mbs.

    i understand what it does in theory, but do you see any difference using a fixed channel vs. ACE? Also, how can i use only one?

    Select the Adaptive Channel Expansion Dropdown Box and Select Disable and save your settings under firmware version 1.0.15. Your connection speed should drop. You will habe to test the throughput before and after with something like IPERF.

    Use firmware 1.0.13 for nearly always-on 40 MHz "Static Turbo". I have confirmed this with WI-SPY Spectrum Analyzer. Version 1.0.13 is stable for most uses and the second channel is active unless the neighboring LAN is very close. Version 15 was Linksys Knee Jerk reaction to Tom Higgins weird "good neighbor" test. Tom has ranted and raved about using 40 MHz wide channels since Static Turbo was released a few years ago. Higgins test are flawed and biased. Nobody questions why he removes antennas from his 54g router and test to see if the signal gets degraded when the 40 MHz ACE is on. Tom, you are going to eventually burn up your 54g router due to the high SWR you are creating! This is a ridicules test and proves only Tom had to go to extremes to find a problem with ACE. Now all the manufactures are running to rewrite firmware to downgrade to 20 MHz G mode for any faint signal around. This guy terrorized Static Turbo and is now focused on Pre-N and N. Why does Tom Higgins want the earth to stop at 20 MHz? He never complained when 54g was new and hogged 2 channels of the older b standard? This is why we use say 10 channels. 54g changed that to 3 channels and now Turbo and ACE are going to 2 channels. Tom should stop complaining, 40 MHz is great and should always stay on! It does not interfere unless you remove your antennas. Bring on the new technology and ask the FCC for more spectrums Tom!
