I'm having trouble enabling wireless security on my Belkin N1 Router

I just spoke with Belkin Technical support. Instead of assisting me in setting up WPA security – which is what I wanted – they walked me through the process of setting up WEP security!? His explanation was that not all of the Windows operating systems support WPA!? Really?! I can't imagine an operating system developed in the last decade that wouldn't support WPA! Is there a new protocol that has surpassed WPA in popularity?

WPA2+AES is requirement for Wireless-N
Their router guide says 802.11n DRAFT which means it may or may not support Wireless N

It will support 802.11n if it says draft.  All certified 802.11n devices were draft before 802.11n was ratified.

1) Are you wired or wireless when you try to change the security?  You really need to be wired for it to work....
2)  Are you being prompted to login to the router before you make the changes?

I am wired when I try changing the wireless security settings. I am prompted to log in, at which time I enter the admin credentials.

I have found conflicting information regarding this on the web. The Dell site recommends bypassing the login by leaving the password field blank. On the other hand, I've seen information suggesting that an actual password is required prior to making changes.

Almost every Belkin router I have seen has a blank password for its default login and they all squawk if you enter the wrong password.

If you can login as admin, no need to enter another password if you want to change any settings.

The above is true for all routers I have dealt with in my IT support career.

I'd try a different browser, just in case security settings are stopping you from changing anything or running scripts on the pages.

I have had a chance to try a different browser, but haven't had a chance to change the firmware. Unfortunately, the router and I are not are no longer on the same coast. It's probable that I could get remote access to the computer to which It's connected, but not on a consistent basis.  It's more likely that I'll be able to convince the end-user to replace the router.

Although all of the participating experts contributed valuable information, none of it got me over the hurdle. in all fairness to them, I have not had time to  try  all of their suggestions. It's likely that I will need to  to fiddle with the firmware. Otherwise, I will have to  replace the router.

I'd delete the question then, rather than just accept any answer.

In general I would agree, but that has always gotten me into trouble. One time when I tried deleting a question, I was told by an irritated expert that being told that there is no answer is in fact a legitimate answer!? Consequently, I find myself trying to please everyone – which is not fair to anyone.

I understand babyb00mer but in this case the chosen answer was really more informational than 'the answer'.

You didn't get an answer that worked out so personally I'd have no issues with the question being deleted.

Yes, I quicly repeated relevant parts of Wifi-N, namely that once WEP or WPA1 is seen client cards/drivers from 2014 onwards (like windows 8 and better) will downgrade to wireless-G

I came across this thread and will share my solution. I have a Belkin N1 Wireless Router model no. F5D8231-4 with the same problem when attempting to set or change the Wi-Fi security mode with pre-shared key PSK. The router is old, and it has a compatibility issue with modern web browsers. Previously I used to operate the router using an outdated Safari browser, but after updating my computer this does not work any more. I have tested Safari, Firefox, Chrome and Chromium web browsers, and all have the same problem. Finally, I tried the Arora browser (on Linux Lubuntu 14.04), and it worked. I have changed the security settings several times today, without any problem. So you probably need an outdated or very basic browser to change the security settings on this router.
