RN424: problems when accessing via WiFi

Question

Summary: I can access the RN424 drives via my network when using a wired connection and 5GHz Wifi, but some platforms can no long, while they used to, access thge NAS via 2.4GHz WiFi.

Details: I have three MS Surfaces, connected as follows:

Surface 4 Pro #1 wifi <> router <> switch <> RN424

Surface 4 Pro #2 wifi <> router <> switch <> RN424

Surface (original) wifi <> router <> switch <> RN424

Surface (original) can access the RN424 via wire, 2.4GHz or 5GHz wifi.

Surface Pro #1 can access the RN424 via wire or 5GHz wifi. When using 2.4GHz wifi, a panel indicates a password problem when accessing the RN424. I believe that this behavior began several months ago, since I had originally configured this for 2.4GHz wifi for the increased distance.

Surface Pro #2 behaves the same as Surface Pro #1.

Surface Pro (original; ~10 years old) can access the RN424 using wired, 2.4GHz or 5GHz wifi with no problem.

I cannot see how the wifi speeds would affect password protocol with the RN424, expecially since this is relatively new problem.

Insights are, of course, welcome.

Are you getting errors on accessing the shares when&nbsp;connecting with 2.4Ghz? It seems weird since connecting to the same WiFi network using 5Ghz works. Can you send a screenshot of the error

If it is Windows telling you it's a password problem, don't believe it.&nbsp; It will often tell you that you may have a password problem when it is something else all together.&nbsp; Do you have something in your router set to separate the two frequency ranges (like one set up for only guest access)?&nbsp; Or are you accidentally&nbsp;connecting to the guest access instead of the normal one on the devices that only have that frequency?

I agree, especially with these symptoms.
&nbsp;
I also suggest trying to ping the NAS IP address over both the 2.4 gHz and 5 gHz connections from the surfaces that are misbehaving.&nbsp; If that works, then try to connect to the web interface next (https://nas-ip-address/admin - using the real IP address of the NAS of course).

Here is the screenshot.&nbsp;This occurs only when I try to access the NAS via 2.4GHz wifi from either of the Surface 4 Pros. Each of the Surface Pro 4's are able to access the internet, so they have access through the router to my local network, where the DSL modem resides.

Using 2.4GHz on the Surface Pro 4, I am able to access the NAS admin page; I went as far as the username/password login prompt but didn't actually log in.

When I try to access the shares via Windows Explorer is when the username/password violation thet I attached in a previous message is displayed.
