I would check using CLI whether those config changes are there on your AP? You can find any un-saved configs using below CLI command. In that way you know configs will be there, if not saved you can save it in CLI (write mem).
AAP1#sh archive config differences nvram:startup-config system:running-config
Also I would try with different image (eg ap3g2-k9w7-xx.153-3.JC)
Same problem here with a 2702i using the following software:
You can save config changes in the CLI and it will show on the WebGUI but if you try to change anything and apply via WebGUI it faults with 404 error page not found. Any solutions? I tried all browsers and even different machines same problem. I went as far as I formatted the AP and redownloaded software to make sure not corruption issue. This is very odd. Maybe revert to a previous version or this version has missing files. Any help would be appreciated or suggestions?
I don't believe it is the software as the three other people on this thread and using completely different versions, so that would not make sense that it is the software. Has anyone had luck figuring out what the issue might be? Browser? Does the gui rely on specific HTML or standard to operate correctly? just throwing ideas out there. Thanks.
its confirm 100% software version issue, if you still have issue I can help with remote.
try this video,
You should see how many folks here have upgraded and or downgraded to an image one higher or lower and had the same issue until they downgraded a few trains or minor releases. HTTP on standalone ap's was not the greatest and that is why many whom been around standalone would only use the cli.
Downgrading to earlier firmware doesn't solve the issue. Appears to be the 1-1-2020 credentials expiration bug.
I have the same Problem.
404 Not Found
Where ever in web UI you click Apply you get
The settings shown on this page will be updated.
Click 'OK' to continue.
And then 404 Not Found. On all browsers. On all units. Many people across the globe have it.
You have released software to the public without even a simple smoke test? - what does it tell about your Quality! ?
try this, I was also facing the same issue
Spent some time trying to pin this down; tried a few things - formatted flash with clean IOS install (verified SHA to rule out corruption), tried older version... all with same error. Then I found a thread discussing this same 404 error/issue in regards to the "January 1, 2020 SSC" error:
Now trying to find a workaround that actually WORKS to see if this solves it. If anyone can come up with a step by step quick fix for this, that would be swell!
