Improving Wifi via Channel (Frequency) Selection - Rectify Wifi Environment Congestion
article #1400, updated 6 days ago

Here is a very good comprehensive step-by-step discussion:

pixelprivacy.com/resources/best-wi-fi-channel/

Mac is listed first, but Windows is well-discussed after, a Linux command-line (!) method is nicely explained afterward, and Android and iPhone afterwards.

The only item I might suggest, is that the 5 GHz band can sometimes produce far better performance, depending on many factors, including the makeup of walls, if and only if both the WAP and all client devices support 5 GHz. I don’t buy or recommend WAPs which do either/or though, just both, and on a client, if I get 4 bars with 5 GHz and 5 bars with 2.4 GHz, I generally see better throughput on the 5 GHz.

Try LinSSID. Graphical, 2.4GHz and 5GHz, and works very nicely. It is in many distro default repositories.

Wifi for Apple has to have WMM
article #435, updated 3103 days ago

See here:

http://support.apple.com/kb/TS3727

Any WAP or wireless router, to connect reliably to Apple products, needs to support a QoS-based standard called WMM. Most if not all current Netgear products do support this. Others are not listing it one way or another. Some vendors list something called “movie mode”, but this writer has not been able to confirm whether this is real WMM, despite a discussion with vendor support.

30/30/30 hard reset for WAPs
article #424, updated 3137 days ago

For many WAPs, the following procedure is a good way to assure a reset to firmware defaults. There is, reportedly, a ‘recovery mode’ into which the below can send some ASUS WAPs, but for most it’s just an authoritative reset.

  1. Plug the WAP into power but not network.
  2. Wait until its lights stabilize.
  3. Press and hold the reset button for 30 seconds. Do not let up the button…
  4. Unplug the WAP and continue to hold reset for another 30 seconds…
  5. Still holding the reset button in, plug the unit back into power, and hold reset for 30 more seconds.

Many WAPs will respond with a ‘waiting’ or ‘working’ indicator, which means that the WAP is in the process of setting all configurations to default. Once that’s done, it’s ready to be set up again.
