" the page will tell me there is either a certificate error or a certificate problem " this is phrased incorrectly, it is your browser that gives you this message, not the web-page retrieved from the server.   check if you are using the same nameserver when using the Cisco as when using the connection direct to the modem check your time-sync when using the cisco router in your browser open the certificate details and look for hints why this is seen as a problem. ...

RTU licensing gives you the flexibility to "move" licenses from one device to another without going through a registration process. Also in a test-environment, you can temporarily use a higher license to perform your test. I also think you have the right to activate the license in advance of receiving it, when the order is al ready submitted. But still if you purchased one advanced license, you should have only one device with this license active.   be aware (especially with a maintenance contract) providers may ask you to cooperate in an audit and check whether the administration of devices/licenses matches what's active. ...

>>> It's an option but we want to avoid to create more SSID in our infrastructure to save "airtime" <<< if you got one ssid's using 5GHz only and a different using 2.4GHz only , there is no increase in "airtime"???   NB! the airtime problem is mainly in 2.4GHz band using 802.11b speeds so there should be little impact when creating an extra ssid that uses 5GHz only. ...

- Is the AP in local-mode or flexconnect mode? Local mode -> the AP passes all DHCP requestst to the WLC and the WLC either 1) handles the request by own dhcp server configuration (I guess this is not configured) 2) performs dhcp-proxy (similar, but not equal to dhcp-relay) 3) just drops the packet on the (v)lan and the packet is forwarded by the ip-helper on the switch => please specify more info on the WLC interface configuration. - is the wlc in dhcp-proxy or in bridging mode? => you did not answer this one ? this is important for the dhcp server return packets, In proxy mode the wlc uses its management adress to forward the dhcp packets to the dhcp server can the dhcp server find the route back to the wlc? (I assume for the ip-helper all is configured ok). - does the ap itself get a dhcp address? Yes there is no problem with the AP. => no further info needed. - is the dhcp server directly connected to the vlan where the clients reside or do you use multiple vlans? No I'm using dhcp helper configurations, helpers are configured on L3 switches. - do you see any requests in the windows dhcp server logging? Yes I see the requests and also see some DHCP NAK packets. -> do you have multiple/ dhcp-servers? redundant /failover/load-balancing, it can mean one offer is accepted and the other recieves a nak. so do not neccessary mean there is a problem. but can also indicate you've got a rogue dhcp-server on the network? it could also indicat you've got not enough addresses in the pool, so addresses get exchausted. => needs further investigation ...

hm..... I'm doing some guessing here IOX Server Address: FE80::200:CFF:FEB5:D079; Port: 22222 can you try accessing the router using its IPV6 address on port 2222?  maybe access to the ipv4 address has also been changed to use port 2222? ... View more

Yes, The wlc has insifficient information to process the request    :-(   I mean there are lot of possibilities why this does not work and you need to supply more information. - Is the AP in local-mode or flexconnect mode? - is the wlc in dhcp-proxy or in bridging mode? - does the ap itself get a dhcp address? - is the dhcp server directly connected to the vlan where the clients reside or do you use multiple vlans? - do you see any requests in the windows dhcp server logging? ...

you mention a router between your modem and your switch. DHCP broadcasts should not be forwarded by this router unless you configured a ip-helper. if the router is not physically between the devices but logically then there is another explanation. ... View more
