NSS2000 interface problem

Hi All,

I have a strange problem with nss2000 web interface: when I try to login to the NAS from any browser (IE or Firefox), the web interface is extremely slow and sometimes I need to refresh browser page after login to see the web interface. Does anyone have the same problem?

Thank you!

I have seen this slight issue myself with IE8 and have seen some past posting around this as well but not sure which NSS firmware was referenced.  What firmware version of the NSS are you using?  I see 1.16 listed as the most current in the software downloads, so if you are running older fw than that I suggest downloading this version and updating your unit as a first step.

Best Regards,

I have just updated the firmware version to 1.16-3 this morning, but the problem persist.

Thanks for your reply.

Have you tried clearing the browser cache before accessing the NSS?  This seems to be a common fix to this issue I believe.

This issue is not with the NAS, it is with the changes from browsers. It is common very slow to access to many devices to work with broswers before IE 8 or Firefox 3.5.X. There are competitive market for browser to make it works much faster, mainly between Firefox and IE.  IE 8 and later version of Firefox broswers are sending large number of http connections (8 http connections) to query the data to any devices (NSS is one of them) for display data on the browsers. The more http connections simultanousely, the faster data will be displayed.  Because NSS limited number of connections of http at a time ( 4 http connections), the browser thinks it has not done with query the data and lkeep trying. User think it the NAS but it is not. Any browser version before IE 8 or firefox 3.5.X are working fine. It is the incompatible resources from later version of browsers to resources reserved in the NSS.

I believe, this issue is across the networking community for small devices with Web GUI interface, particularly for user who is using the latest browsers.

The work around is:

1. When access to NSS, give it 2 seconds. Move the mouse cursor at the end of the URL. click "Enter" on the keyboard for data display.

2. Use IE 7 or previous firefox version before 3.5.0

3. Use Safari or Google broswer as different browser to access to NSS GUI. Cisco is not official supported these browsers, but they are working fine.

Maintenance release: There is a fix to allocated more resources from the NSS to handle these new number of http connections  requested from browser. We are working to address this issue so user can use any version of the browser.

I have the same problem.
I will try an older Firefox version.

Since I'm stuck with the original fw release of the nss2100 I'd tried to upgrade to 1.2.1
But it keep saying corrupt fw try to re download.

Any idea ?
