Hello,
I have some strange problems with some of my clients. Imagine a building with several floors
e.g.:
- A client is connected on the ground floor, no problem. Internet is ok.
- Now he enters the first/second floor. His smartphone is now connected to another access point, but shows him "no internet"
- He goes back to the ground floor and internet works again.
- On the access point of the first/second floor there are many clients happily connected without any problems. When one of those problems were reported a collegue went to the building and connected to the same access point at the same time the other client had problems without any issue.
- On the capsman controller, you can see the IP/MAC on DHCP lease information page of those clients with mentioned problems. But it is not possible to ping those clients from the controller. Also those clients cannot ping the gateway ip which is on the controller. A client mentioned that he sees an IP address with ipconfig, but there´s neither DNS nor gateway ip address information given.
So, what kind of problems do I have? Something with the DHCP server? I was running 6.40.* and updated step by step and now I´m on the latest 6.41rc52 release. I´m runninng that CAPSMAN based forwarding setup for years (since the first HAP/WAP AC devices appeared with hundreds of clients concurrently connected) What could be the problem? Any hint would be helpful?
Regards
Re: CAPSMAN based Wifi: Connected, no internet
Hello,
I have exactly the same problem. My router is a RB2011UiAS-2HnD-IN and I have 3 HAP AC working as access points. The only difference is that I have a local forwarding CAPSMAN setup.
When switching access point, the clients get the "Connected, no internet" message for about 5 minutes. I cannot ping the gateway during this time. Then, after those 5 minutes, they begin working normally.
Before switching to a CAPSMAN setup, everything worked perfectly, the problem began when I started to use CAPSMAN.
I suspect that maybe it's related to loop protection, I tried to configure it as off in all interfaces to no avail.
Help, please?

Hi!
I can only confirm this, but with a wider variety of devices...
The router (& CAPSMAN) is a RB3011UiAS running, CAPS:
The 2.4 GHz network when connection spends around ~20 seconds obtaining an IP address, gets one that's in range and there's no internet.
The interesting thing is that the 5 GHz network doesn't suffer from this issue.
Some clumsily exported data from the CAPsMAN:

Did you solve the Problem?
Re: CAPSMAN based Wifi: Connected, no internet
Hi,
I'm having the same problem. Only difference is that when I reset the router and wAP the internet is coming alive for a few hours, than drops.
I don't get the no internet message, just internet is not working. When I look the CapsMan connected devices I see that they get IP from DHCP and on client there is written the GW IP of a router and public DNS addresses aquired by the DHCP.
I'm runing the RB 2011 UiAS-2HnD and wAP both on the 6.42.6 mipsbe.
So in short
there is always connection to the LAN, but for the WAN it drops after some hours.
I set up the channell reselection to 30 min, since I have crouded wifi enviroment (lots of neighbours) and set the channels 1, 6, 11 for selection.
The problem appears randomly but only on wAP not on the RB2011.
Any Idea what to do?
Regards

Hi
I solved this problem with disabling local forwarding in datapath on controller. Used 6.42.1-6.43.2 firmware with such problem.
