I have 8 AP’s in my building model cn410 on firmware version
3.11.4.1-r3 but 2 of the AP keeps on giving me problems, and it looks like when number of clients go over 21 then clients connect successfully but with no internet.
when the move around the building to different location with different AP then they can connect again, is there maybe a best practice document that I can follow to see if I’ve set it up correctly?
first of all, I suppose that the access points are all connected to the same source of DHCP (A router for example).
If so, would you share with us how you set up the DHCP and your LAN setup if there are switches in your LAN?
One more, when you say 21 devices connected, do you mean on all 8 APs, or 21 devices on one AP?
Which router do you use on your setup?
The best way to around this is to have a specific VLAN traffic to each AP with its dedicated DHCP IP subnet, when you plan to have many devices beyond 30-40 on each AP. Then, you can NAT the different subnets to internet.
We are also having almost a similar problem but with the e410 APs. We have 2 APs in a building connected from a cnPilot r190W through LAN.
The deployment is for a student accommodation using blackboard learning portal. Others can connect to blackboard with no hustle, whereas, some can connect but with no internet access or it buffers throughout lessons. Once off blackboard they can browse the internet with no problems. What could i be missing. Kindly assist…
Latest software is released for cnPilot series 4.2-r15 , can you please upgrade your AP’s to this build and share us your observations this build should the issue
Even in 4.2-r15 if you are still facing this issue then please share us the techsupport file of the AP, when the AP is in issue state.
You can download the techsupport from following location
i have also a same issue, when user roams from one place to another and auto reconnects with the same SSID the session is created but internet does not work.
We also observed, A device remain idle for some time its showing no-internet but session connected.
access point:- e410
It sounds like you are unable to resolve host names. Try to do the following from your CLI(see below) . I would suspect that you might need ti change one of your DNS servers… I’d change the 8.8.4.4 to 9.9.9.9or 1.1.1.1
Was the solution to this problem found. Had a ticket ( 278655) open with cambium but could not get much help, we sent several tech files with no solution. We had to remove some of the cnPilot R190 s with another vendor (tenda) and the problem was resolved immediately. My problem is that we still have many cnPilot deployed experiencing the same problem and its a loss for us to remove these devices and replace them with a new vendor all of them.
