VAP & DHCP problem

RouterOS General
1

Hi to all,

I’m experiencing weird problem.
I have 433 with 2 radios. Hotspot setup and running ok, dhcp ok, everything on a single bridge.

I’ve added few more wireless VAP to atract users, all added to same bridge.

Here is the problem:

  1. user connects to SSID 1, gets IP and login page, all ok
  2. user goes to SSID 2, gets IP (the same one), but no login page, browser after a while reports an error, like dns is not ok :frowning:

When you repair connection in winxp (disable/enable wifi adapter), you are connected to SSID 2, you get the same IP & rest, and you get login page OK. :confused:
If you go back to SSID 1, you’re stuck again, no login page?!?! :frowning:

Is there a way to resolve this problem? It’s like DHCP is not sending all info to client. Can we somehow reset dhcp when same MAC client connects to another interface? :confused:

Tried with 2 laptops, 3 different wifi cards, always the same…

BR, Petar.

Make sure RSTP protocol is enabled on the bridge,
/interface bridge set <used_bridge> protocol-mode=rstp

Hi,
yes, RSTP is enabled on that bridge.
When I monitor wireless registration on PC, I can see that client is registered on 2nd VAP before he’s deregistered on 1st one (ie. I see two R’s in interface list for a second or two).

Log says that dhcp is deassigned from client and few seconds later assigned back.
