Unfortunately a previous solved bug was reintroduced with this firmware.
Firmware 1.0.23.7 seems to have a severe VLAN bug - WiFi Access Points - (grandstream.com)
Dont know if its the firmware or the cloud update, but the total (client usage) is wrong, some of the client are alreade 5 hours on, watching youtube, but says the total is 203.4 KB. Impossible. We use GWN7605 and at some places GWN7630LR devices.
Thank you very much for the hint. Have you already opened a ticket at helpdesk.grandstream.com? Is Grandstream aware of the problem?
Unfortunately (is it?) I’m not able to reproduce till now. Only thing I changed before this firmware upgrade was deactivate 802.11 k/r/v. Will monitor for the rest of the weekend, might test with this activated on the weekend.
ah ok, I misread, that Grandstream had disabled that features
keep in mind that you can also activate/deactivate the single setting
Not sure if it is related: enabled Voice Enterprise yesterday and this morning I ran into the same problem. Updated my ticket, hope support can find a cause. Disabled Voice Enterprise, will keep a look at the logging.
Also with Voice Enterprise disabled, the problem is occuring. Might be related to my GWN7605LR, downgraded its firmware and reenabled Voice Enterprise. Kepping a close look at the router log.
And I still have open ticket for first case reported. It makes me think that bug was never solved. Just temporarely resolved by “accident”.
