Feature and severity: I have a bug (appears to be) with SFOS v18 v3 and APX 740 wireless access points that I consider moderately impacting.
Summary: I am unsure of the trigger, however, every now and then (appears random but multiple times per day) all 3 of my APX 740s “appear” to go offline then come back a minute or two later.
Observed behavior: All 3 APs drop all clients and the SSID isn’t broadcast then after two or three minutes they come back. All the clients need to re-home to the best AP again. I run 3 740s using an XG210 as the controller and have 3 SSIDs (one for only 2.4ghz, one for only 5ghz and one for a guest SSID that’s 2.4 + 5ghz). I thought it may be related to auto channel selection so I manually set the channel on both 5ghz and 2.4ghz radios on all APs (different channels of course). The problem persisted though. I don’t recall having this issue previously but it may have been happening without me being aware. I say that because I’ve recently added significant home automation devices so now it’s very noticeable when this happens.
i tried Sophos central wireless and it’s worse. I won’t go back to central until several releases come out.
Reproduce it: This happens on its own many times a day but nothing that forces it that I’m aware of.
Supporting logs: The log viewer, under “SYSTEM” shows (just a brief excerpt for brevity):
can you please specify wich fixed channels do you selected?
for 2ghz (3 APs):
1, 6, 11
for 5ghz (2 APs):
side note: I could re-enable auto selection (I only ever used auto on 5ghz) and see if it happens. Still no new AP offline entries in the log.
Started to occur again. I noticed memory use creeping up slowly. I have an XG210 and at boot it starts just under 30%. Now it’s around 50%. With auto turned off, no firmware updates nor any changes made by me, I’ve no idea what config is even being sent to the APs:
Memory use up to 53% now as well. Maybe unrelated but worth mentioning with the unexpected reboot 3 days ago.
Could you show us a little network diagram with your APs?
Are you using VLANs or are the APs directly attached?
