Cannot Connect To Open (Guest) SSID

I currently have a working guest SSID called RV-Park. It is up and running with no issues as well as open with no authentication. When I assign the RV-Park network policy to my test AP at my desk I am unable to connect to it...

I am able to see the SSID but I cannot connect to it with my Windows phone or my laptop. I've also tried creating a test policy, completely open, and assigning it to my test AP. The AP is able to upload the config and reboot with no issues.

All AP's have the same management vlan 200. Our guest vlan is 801. These vlans are extended to my switches. What's really weird is that my test networks and guest network 'were' working before I left for a week...

Nothing has changed on my network and I can't figure out the issue here.

Have you tried the VLAN probe tool to figure out if DHCP works from the AP for those VLANs?

Also, consider using the Client Monitor to find out what exactly breaks and where.

VLAN probe was successful on both 200 and 801. Below are the results of the Client Monitor:

Hmmm... so your client can authenticate, but its DHCP discover message is not passed through / answered.

I'd try the following:
- Create a new, open SSID with a new user profile, all default settings, and try both VLANs for users. Would be interesting to see if they can connect via VLAN 200, or if the problem is on both 200 and 801
- Swap a working AP with your test AP - does this one work in your office, and does your test AP work where the working AP was?
- Do a default reset of the AP in question and reconfigure it from scratch.

The latter can sometimes fix a lot of "weird affects".

I pulled a new (out-of-box) AP. Updated it's firmware to match that of the HM and assigned it my test policy. I was able to connect to the AP with my Windows phone...

The AP's management interface is on VLAN 200 and it received a DHCP reservation. Also, my phone received a VLAN 801 DHCP reservation.

I did update all AP's firmware to match that of HM which is 6.1r3a.

I'll try defaulting the non-functioning test AP next.

Unfortunately this is still an intermittent issue typically seen on older devices. And, Aerohive support isn't all that great or responsive... Either way, if anyone has some idea's it would be good to know.

Can you take a look at your DHCP server and see if it is receiving / processing the client DISCOVERs?

J. Goodnough, I'll check the server. I do know that for 99% of our users there are no issues. So, what would the server tell me? It seems that this is more of a client issue...

You'd be looking for the server to be properly handling the DISCOVERs. What you're seeing is the client repeatedly asking for an address and not getting one, so this will help you isolate the problem. It sounds like what you expect to see the the server assigning a lease. If that's true, then you'd be able to further limit the scope of the problem.
