    Wireless connections are far less stable than wired ones, and if something goes wrong with the upload, you could have problems. "Brick" problems.

    Loading it from a web site might help a bit, but you still may lose your connection to the Internet in the middle.

    Anything that increases your chances of failure is a Bad Thing (tm) and is to be avoided. The most stable way to upload firmware is:

    1. Computer connected directly to router using high quality patch cable. Nothing else but power connected to router (no other clients, no Internet).
    2. Router recently reset to factory defaults, with as many services (wireless, QoS, etc) turned off as possible, and freshly restarted.
    3. Computer and router both on UPS (battery backup power supply).
    4. No firewalls or anything running on computer.

    After the upgrade, wait an extra minute or two to make sure the firmware is fully installed, log into the router and reset all settings "factory default", change the admin passwords, rekey all of your settings, restart the router, THEN hook it up to the Internet, test it, and connect any other clients.

    "Can" you do it with clients connected, over wireless, connected to the Internet, not on a UPS, etc? Sure, you CAN. It will probably work, too. But a few extra minutes' effort reduces your chances of making a shiny blue brick. Your router, your call.

    I load WRT54G firmwares wirelessly without incident. My router is in the next room next to the cable modem. I receive an excellent signal level at my computer of -25 dbm and have a laptop that could allow a direct wired connection, if necessary.

    If your connection is strong and stable, flashing firmware wirelessly should not be discounted.

    But, this approach should be avoided and not recommended if you want to play safe.
