Which AP to choose

Hi,

 

We want to replace our Fortinet AP FAP221C with something better. We have problems with Apple devices like iPhone and laptops they frequently disconnects from access points. Can someone recommend more reliable Fortinet model?

 

Thanks,

Aigars

You can use whatever AP you want really. FortiAP integrates directly to the Gate which is nice. The 221C is good for most home\business users. If you have a ton of clients (and I mean A TON) you can look at the 320/321 but it is usually too expensive and overkill for home use needs.

Hi Algars,

Can you post wireless related config here so we can see whether some parameters can be fine tuned?

 Thanks,

Okay:

I loved my 321C that I had deployed at my house. Pushed 50 or so of them to a university client as well and they have nothing but great things to say.

We have 221B and 221C in our office. One Macbook Air user keeps complaining frequent drops. But I haven't gotten any complaint so far from iPhone users yet.

The Macbook Air is regularly connected to 5GHz radio on 221C, while two more Win laptops are connected to the same radio with the same SSID, which never experienced the problem the Macbook user is experiencing.

I researched on Google and found similar symptoms but all seem to be related to Mac OS X side.

 

For the recommendation, I don't have anything else tested. But if you can afford I would recommend 3x3 MIMO models for better "air" performance.

How good are Aruba and Rokus working with Apple hardware?

Some general suggestions based on config

1) if WIDS is a function you need, you can consider to have some dedicated radios with mode set to monitor to do that. When radio is put into access point mode with WIDS enabled, it does off-channel scan while it serves client

2) if DFS channel is used, you can consider to add a couple of  more channels in the available channel list just in case there is radar signal in that area which AP has to wait until it can use that channel. During that time,  there might be a coverage hole 

3) When DARRP is enabled on AP and it decides to change channel, AP will send a standard channel switch announcement frame to let clients know. Some apple clients don't take that well. The symptom could be the wireless icon showing connected/greyed out. To workaround the issue, you can use fixed channels as you did for some of your APs or enable DARRP with an off-hour schedule

4) not sure about your VAP config. If you by any chance use enterprise mode, please disable gtk/ptk rekey or set it to a longer duration. Some clients don't work well with that either. 

 

If you still have issues after considering above, I suggest open a support ticket with Fortinet TAC who can help take a further look at your particular deployment such as network topology/radio environment/broadcast-multicast traffic volume etc. 

 

Thanks

I have no knowledge of either situation. I don't have any Apple devices myself.

I don't want to discourage anybody but with my experiences I have to be very patient to work with TAC for WiFi related issues(FAPs, FWFs), compared to the patience to take when I open cases for other FW/routing issues with FGs.

When I complained about it to one of Wireless SEs, he mentioned they were working on org change to make their support team closer to development/SE teams to provide better support. Hoping it would happen in Q1 or Q2 this year.

Avoid using 2.4 GHz channel 1 with Apple devices. Especially in the later iPads, the chipset freaks out when using channel 1. Dropping connections, authenticating correctly and then going offline/not receiving an IP, ...

 

I'm running 2 FAP-221C at home and use 2 Macbooks, 2 iPads and an iMAc without issues, but had to disable channel 1. There are several posts out there but Apple is ignoring the message...
