Running a fortiwifi 80cm with all security features disabled and a wide open accept policy. Connection from windows and Mac laptops is great, but I have consistent issues coming from my ipad and iPhone. Everything is dhcp and all devices are coming in through the same wifi network running wpa. I can' t identify any errors in the log file. Running firmware 5.0 build 208 Anyone have any ideas or troubleshooting steps? Thanks!

Currently do not have access to an ipad/iphone to test their wireless connections, but some things to try/consider: - Set the encryption to use both AES and TKIP - Define a custom AP profile (set type to the FortiWifi 80CM) (The default automatic profile setting seem to give some of our customers connection issues.) - Try adjusting/add/moving channels - Trying Limiting the band to 2.GHz - Disable/block UPnP traffic to/from the wireless interface (some people reported this fixed their ipad connection issues). The built-in wireless controller does have some nice debugging tools. Also consider consulting Apple' s own Wireless troubleshooting guide. If this 80CM is older than 3 years then consider the possibility that it may be one of the batch of 80CMs with a faulty wireless chipset. In that regardless you may want to contact Fortinet support to determine this. (Off hand I do not know which units by serial number are suspected.)

Thanks for the assist here! I enabled AES+TKIP and created a policy to block UPNP. Not sure which fixed it, but for the last 15 minutes its been clear sailing and connection issues seem to be gone. I should really remove one to see which fixed it, but after fighting this for 6 months, I don' t want to breathe on the box!!! Thanks again. Really appreciate this.

Hello Shiltsy did you determine what seemed to fix it? I have been experiencing similar issues with 80CMWifi and a 90DWifi

It' s still not fixed. I ultimately stood up another wireless router just for my IOS devices. I upgraded the Fortinet box to the latest firmware tonight to see if that solved the problem, and it did not....

I have had my share of FortiGate wireless headaches. I have a new one: I just got a new laptop with 7260-AC wireless inside, and it continually disconnects from the FortiWiFi-60C. I have had to resort to plugging in a LAN cable, because wireless was so unreliable I couldn' t get any work done.

Still the same with v5.2.5,build701 on FortiWIFI 40c, please provide an update for this anoying disconnects!!!!

Cannot be that there is no solution for this?

 

Tested iOS Devices: iPhone 4s/5/6s, iPad 2, iPadmini 2 ... all the same!!! so don't tell me it is an apple Problem if the Problem only resist on the Fortigate with any other router no disconnects!

 

Really Fortinet Customer Support????!?!?

Hey,

 

I've been experiencing an issue very similar but not singling out iOS devices alone (I'm seeing these results on all Apple devices).  At first thought it was a DNS issue with my ISP (they replaced the modem because it wasn't IPv6 compatible).  Still having the same problems.  On the Mac laptop webpages will not load no matter what the browser without several refresh attempts.  Typically 2 or 3 before the webpage script goes away and I actually see visuals... The iOS devices will just stop loading - toggle the wireless off and back on for a little success but the end results are still the same (2-3 seconds of loading and it stops - cellular data will load the pages/video immediately so its not the source).  Running a FortiWifi90D which is now at the latest firmware (nothing is helping) so I hoping I can find some light here... Thoughts?

 

When I lose connection on the mac I can run a steady ping to 8.8.8.8 or google.com which shows packet loss galore.  Run those same tests local on the Fortigate unit and it never misses a beat...

 

Thanks Michael

Hi,

 

I'm also having problem with my FWF60C local wifi and one FAP-221C. Iphone and ipad are having problems (not loading webpages while browsing at some moment, not all the time). Surface Pro or HP laptop have no problems at all.

 

FGT is now on v5.2.7,build718 and I've just done the upgrade of the FAP to v5.2-build0262. Hope this will help, I did read the release notes but there was noting mentioned about unstable Apple wifi, so chances are low...

 

Next step will be upgrade FGT to 5.2.8.

 

Have any one find a stable release or solution ?

 

Thanks,

Kind regards,

Luk
