Hi guys, new here. Hope topic is on right place.

So i have Siemens gigaset sx763 with DD-WRT v24-sp2 (03/08/12) std - build 18687 on.

Device is connected to my main router/modem from where i get internet with LAN cable, so i set WAN connection type to Disabled.
DHCP is off because there is one on on main router(tried even with DHCP set to forwarder).
Phisiscal wireless interface is set with wpa2 sec. for private wlan, and one virtual interface for guests.
I have created new bridge to which i have assigned virtual interface and set different ip(which is in different subnet).
And i have assigned DHCP server to that new bridge.

Problem is that after that gusts can't connect to that virtual wlan because they can't get IP, somehow DHCP won't assign IP.
TY!

Services - DNSMasq - Additional DNSMasq Options, do you have DHCP commands in place for your GN bridge? Here's what I have :

Code:
# Enables DHCP on br2
interface=br2
# Set the default gateway for br2 clients
dhcp-option=br2,3,192.168.3.1
# Set the DHCP range and default lease time of 24 hours for br1 clients
dhcp-range=br2,192.168.3.100,192.168.3.150,255.255.255.0,24h


Also, under Setup-Networking-DHCPD, you need to add DHCP Server for your GN interface

Hi RandomJerk, first of all thank you for helping me.

So under Services - DNSMasq - Additional DNSMasq Options field is empty why do i need this additional options?

As for the DHCP for bridge under Setup-Networking-DHCPD, yes I have assign DHCP to bridge "br2" where my virtual Wlan interface is bridged(see pic in attach).

Quick question. Setup-Basic Setup-Network Setup-Network Address Server Settings (DHCP), do you have Use DNSMasq for DHCP turned on ? If yes, my understanding is that you need to fill in the additional options under DNSMasq to get addresses assigned. Look here assuming you want to isolate your WLANS

OK, so i have followed this tutorial, and i have done everything exactly the same, except DNSMasq options but now i have added them.

So this is what i have done, Use DNSMasq for DHCP server checked. Under options i added:

Code:

# Enables DHCP on br2
interface=br2
# Set the default gateway for br2 clients
dhcp-option=br2,3,192.168.2.1
# Set the DHCP range and default lease time of 24 hours for br2 clients
dhcp-range=br2,192.168.2.100,192.168.2.150,255.255.255.0,24h


and still i can't connect to that VAP(only to that VAP, everything else works just fine).

One more thing can you please tell me what does no.3 stands for after br2 here:


Code:
dhcp-option=br2,3,192.168.2.1

OK, i have followed instriction for firmware install/upgrade
I have done 30/30/30 reset and got Failsafe UI then i load Uimage.bin from:
Code:
ftp://ftp.dd-wrt.com/betas/2017/05-02-2017-r31924/gigaset_sx763/

but after i press submit button i get "This site can't be reached connection reset"?
Then i got back to dd-wrt GUI, make factory reset in gui and tryed to make firmware upgrade through GUI with "gigaset_sx763-webflash-firmware.bin" but then after upgrade finished i constantly hear relay clicking(restartng over and over again), after that i made 30/30/30 reset and I am on Failsafe UI again.
Any clues?

Noup that isn't the problem. Tried that first.
Tried on different computer, different browsers, different cables... Very odd.

EDIT:
Ok so i managed to reflash my SX763 to old version of DD-WRT(03/08/2012) through "FailSafe UI" and it works fine.
But why i can't put latest DD-WRT from link:
Code:
ftp://ftp.dd-wrt.com/betas/2017/05-02-2017-r31924/gigaset_sx763/


Keep restarting when flash with that version...
