Hi Ben, I generally set the following on 2.4GHz: - Use only channels 1, 6, 11 - Set 20Mhz bandwidth - Unless you have old gear set 2GHz-only-N. When devices like Sonos and old printers crop up you have to go back to B/G/N. - 802.11 - Distance indoors - Adaptive noise immunity client and ap - Preamble mode to both - Any guard interval - All chains enabled - Full multicast helper - WMM enabled - Only use WPA2-PSK and only AES More than 1 AP now I use CAPSMAN, sometimes with local forwarding sometimes not. It's just a lot easier in the long run. Try it out. Jason On 27 February 2018 at 08:27, Ben Farmer <ben.farmer@myport.com.au> wrote:
Hi guys,
Hoping any of you can help. We're seeing weird issues with our Mikrotik client routers in deployment, specifically with the 2.4GHz wireless on the hAP and hAP ac lites.
This issue we're seeing seems to affect the 2.4GHz wireless card (Atheros AR9300 in both models) but does not affect the 5GHz card in the ac lite.
Customers are reporting to us the inability to connect to wireless at times, such as invalid security key or failure to connect messages (depending on the customer device).
The wireless interface itself will show as running, but with no clients connected. No error messages are indicated in the log about exchange key timeouts or anything similar, like you'd expect.
Doing anything that performs a soft-reset like operation on the wireless interface will allow the customer to connect again for a period of time. This can include: - Doing a wireless scan. - Doing a frequency usage scan. - Changing channel. - Changing SSID.
Basically any option you can change will fix it, even rebooting the router.
We've tried all different types of software from 6.39 through 6.41, even the latest rc (6.42rc35). We've seen this issue for at least three months now, if not longer. It's not isolated to a particular site either, as we receive reports daily from other customer locations with the same issue.
Initially we thought it was interference, but even then we have customers with very low utilisation and still seeing this issue.
We have reported a case with Mikrotik, but their most recent suggestion was to post in the forums to see if anyone else was experiencing this issue (which surprised me, generally they direct you to support if you write this sort of stuff in the forums).
Below I've included a brief output from the router showing the way this interface is currently set up.
Have any of you seen this type of issue on either this wireless card or others?
/interface wireless security-profiles add authentication-types=wpa2-psk eap-methods="" mode=dynamic-keys name=wlan1 supplicant-identity=room-403
/interface wireless set [ find default-name=wlan1 ] adaptive-noise-immunity=ap-and-client-mode band=2ghz-b/g/n country=australia disabled=no distance=indoors frequency=2462 mode=ap-bridge security-profile=wlan1 ssid="Room 403" wireless-protocol=802.11
