I have a WRT54GS v5 that I can't get upgraded. I am connected to it wireless and I navigate to the "Administration, Firmware Upgrade" page and fill in the "Please select a file to upgrade" field with "WRT54GS-v5v6_1.52.5.002_fw.bin" and click the "Upgrade" button. The progress meter (which looks like a blank text entry field just above the "Upgrade must NOT be interrupted !" message line) fills a couple of times and then the page fails to refresh the 2nd time (after the progress meter has filled the 2nd time). I can navigate back (via browser url address field) to the main WRT54GS webadmin page and thence to the "Status" page where I find that the same (not upgraded) version is noted - v1.50.5 . I've tried this procedure about four time and I'm pretty sure that I can repeat this forever without getting the firmware to upgrade to v1.52.5.002 . What am I doing wrong ??? BTW, I'm upgrading to try to solve flakyness with AP association and DHCP with multiple clients. It seems most likely that the WRT54GS is buggy than that multiple clients are buggy (FYI, they all worked Okay with previous AP that recently died).
