Mikrotik GUI timeouts / deauth

Hi

I have various Mikrotik devices and all have a very annoying “feature”: it kicks me off the GUI, especially after I change some settings. For instance I have a Metal 2HP used as station, I connect to it via Ether. When I change the wireless settings e.g. from B/G to B only it kicks me off the GUI… the GUI appears dead and I need to refresh the page via reload button in the browser, then it shows me again the login screen… Seems to be not a timeout issue, coz it even happens randomly. E.g. I watch teh registration screen and then for some reason it stops to update the values and when I reload it brings up login screen - VERY annoying!

There is no setting for GUI timeout as far as I can see.

All my RB devices are doing that… Metal 2HP, RB951, SXTG… why is that happening?

Which version of RouterOS you have in your routers? All of them have the same version?
Did you try with different web browsers?

All running 6.36.4, however the problem persists since ever… happens with Firefox and Konqueror. Do not have other browsers.

Do you have administrative mac address set to the bridges? Maybe the bridge interfaces which are you connected to are just resetting the mac address on joined interface change made by your config change. Use winbox for the management.

Nope… why MAC should be reset?

I login, go for example into wireless settings, change the band from B to B/G and the GUI “dies”, in about 80% the cases (NOT always). in 20% of the cases it shows “searching for network” and then “connected to ess”, however in 80% the cases GUI is not updated and seems to hang - then I can only reload the page and kicks me back to login screen. This happens even when I just logged in, so after 15 seconds of activity. And the error is as I say random… happens to me since ever I have the Mikrotiks.

I have only seen this when the connection between the computer running the browser and the router
is somehow interrupted, e.g. when you change something that makes the interface go down/up.
Also, it could be that the device is rebooting.
Look in the Log to see if anything is indicated.

Makes no sense… I’m connected via Ether and change wireless… why would ether go down randomly?

Did you have bridged Ether and wlan?

Maybe you have incorrectly bound the IP address of the router?
When you have a bridge between ether and wlan you have to bind the address to the bridge.
When there is no bridge (i.e. you are routing) you should have an address on each physical interface (with different subnets)
and you could lose the connection temporarily when you manage the router using the IP address on the wlan.
Use the address on the ethernet in that case.

no, on metal 2hp where it happens for example: WLAN = client (outside), ether = LAN (inside) and I’m connected via ether. And it happens randomly…

It must be something in your network. Maybe erratic network closer to your management PC? Some over-active firewall?

I doubt it… why it happens when I APPLY the settings?

No idea. I can only tell you that it does not happen on my devices, except when I do something that (temporarily) breaks the connectivity.

Not helpful I know, but I just wanted to add a “Me too”. I’ve seen this on 7 different Mik devices, on several different recent firmwares. Sometimes it’s a device I’m connected to over wifi, sometimes when I’m connected over wired-ethernet (..but wireless in to another device). I think I’ve seen it when I’m on purely wired connections too, but it’s rare that I do that. I’ve only tried it on Firefox. I run a Linux machine 99% of the time, so winbox is a bit of a pain to use, I’d far prefer to be able to use the WebGUI reliably.
