Hey there,
I followed the Kong Guest Wifi Setup Tutorial for setting up a guest wlan.

Here's the Link:
http://tips.desipro.de/2013/12/06/guest-wifi-setup-dd-wrt/

Is there any way to limit the bandwidth for this virtual interface?
For example: I want 75% of my available bandwidth for my own wlan, and 25% for the guest wlan Twisted Evil. I would like to prevent, that guest's download huge files and prevent best speeds for my own wireless network Laughing.

Kind regards,
Patrick

Here you go - you need to modify the subnet and allocated bandwidth

Code:


TCA="tc class add dev br1"
TFA="tc filter add dev br1"
TQA="tc qdisc add dev br1"
SFQ="sfq perturb 10"
tc qdisc del dev br1 root
tc qdisc add dev br1 root handle 1: htb
tc class add dev br1 parent 1: classid 1:1 htb rate 1024kbit
$TQA parent 1:1 handle 10: $SFQ
$TFA parent 1:0 prio 2 protocol ip handle 10 fw flowid 1:1
iptables -t mangle -A POSTROUTING -d 192.168.200.0/24 -j MARK --set-mark 10
TCAU="tc class add dev imq0"
TFAU="tc filter add dev imq0"
TQAU="tc qdisc add dev imq0"
insmod imq
insmod ipt_IMQ
ip link set imq0 up
tc qdisc del dev imq0 root
tc qdisc add dev imq0 root handle 1: htb
tc class add dev imq0 parent 1: classid 1:1 htb rate 512kbit
$TQAU parent 1:1 handle 10: $SFQ
$TFAU parent 1:0 prio 2 protocol ip handle 10 fw flowid 1:1
iptables -t mangle -A PREROUTING -s 192.168.200.0/24 -j MARK --set-mark 10
iptables -t mangle -A PREROUTING -j IMQ --todev 0

Thank you!

Seems like I have to do some homework now.
Thought this could be a checkbox thing or two lines of code Embarassed

Don't use that generator it is outdated, and it will probably not work correct. Use GUI instead. See picture below. If your internet connection is hosted on that router then use wan up/down to limit users, or if you use router in wds sta or client bridge mode than use LAN limitting cause WAN is disabled in that case...

Hi,

In the example image, netmask would you place the guest IP in there and then the main SSID IP?

Thanks

As discussed in other topics script works for downloads only.
GUI method gave me opposite result - it works for uploads only.
Tried with Netmask Priority only, tried with other settings filled - upload only is limided.
Played with Enable Per User Default Limits - the same, uploads only.
