The content on our website is usually updated every Friday. Due to the holidays, there has been a delay so it should be there by the end of the week.

Hopefully you'll have a firmware update for the C4000 v3.6 soon. I've tried 2 different brand new routers and cannot see the 5Ghz-1 SSID showing up anywhere. Tried resetting and choosing multiple static channel. Still nothing. I had thought the first router was bad, now I think a firmware fix is needed ASAP.

Support page for V3 is still missing.

Weird thing is that the main product page lists V1 and V3 but the support page lists only V2.

Please add V3 support page.

That will be reported to the web team to look to get that up soon.
