DHCP-Options

6,192.168.2.1,192.168.2.2

26,1470

option:mtu, 1470

Additional options to be added for this DHCP server. For example with

'26,1470' or 'option:mtu, 1470' you can assign an MTU per DHCP.

Your client must accept MTU by DHCP for this to work.

Wireless

On this page you can configure your wireless settings. Depending on whether your WAN mode is set to Wifi or not, the

page will display either the options for configuring an

Access Point

or options for configuring a

connection

to some local

access point.

Access Point:

Here you can see the Overview of the wireless configuration. It is divided into two main sections

–

device and interface.

One is dedicated to configuring hardware parameters other

–

software.

Device

General

Here you can toggle the availability of the wireless radio and the physical channel frequency.

Important note

: As seen in the picture you should always

Save

before toggling the radio on and off.

Advanced

Here you can configure more advanced parameters:

Field name

Sample value

Explanation

1.

Mode

Auto, b, g, g+n

Different modes provide different throughput and security

options.

2.

Country Code

Any ISO/IEC 3166

alpha2 country code

Selecting this will help the wireless radio configure its internal

parameters to meet your countries wireless regulations.

3.

Distance Optimization

100

Distance to farthest network member in meters.

4.

Frag. Threshold

2346

The smallest packet size that can be fragmented and transmitted

by multiple frames. In areas were interference is a problem,

setting a lower fragment threshold might help reduce the

probability of unsuccessful packet transfers, thus increasing

speed.

5.

RTS/CTS Threshold

2346

Request to send threshold. It can help resolve problems arising

when several access points are in the same area, contending.

Interface

General

ESSID

–

Your wireless networks identification string. This is the name of your Wi-Fi network. When other Wi-Fi capable

computers or devices scan the area for Wi-Fi networks they will see your network with this name.

Hide ESSID

–

Will render your SSID hidden from other devices that try to scan the area.

Security

Encryption

–

There are many modes of encryption, though two distinctive classes have to pointed out.

WEP

Enter the keys that will be used as passphrase for connecting computers and then specify which key will be preferred

above the remaining. It’s sufficient to enter one key and then specify it as the preferred one. Length is important as

well: 10 or 26 characters in length in hex mode OR 5

or 13 in ASCII mode. A hex key may only contain numbers ‘0’

through ‘9’ and letters ‘a’ through ‘f’.

WPA

First select an encryption method: TKIP, CCMP, TKIP&CCMP, auto. Note: Some authentication methods won’t support

TKIP (and TKIP&CCMP) encryption.

Aft

er you’ve selected your encryption method, you should enter your passphrase,

which must be at least 8 characters long.

MAC-Filter

Filter

–

you can define a rule for what to do with the MAC list you’ve defined. You can either allow only the listed MACs

or allow ALL, but forbid only the listed ones.

Client

Client mode is nearly identical to AP, except for the fact that most for the options are dictated by the wireless access

point that the router is connecting to. Changing them can result in an interrupted connection to an AP.

In addition to standard options you can also click the

Scan

button to rescan the surrounding area and attempt to

connect to a new wireless access point.

Backup WAN

Backup WAN is function that allows you to back up your wired OR wireless connection in case they go down. At the

current moment you can only backup wired/Wifi with 3G.

The majority of the options consist of timing and other important parameters that help determine the health of your

primary connection. Regular health checks are constantly performed in the form of ICMP packets (PINGs) on your

primary connection. When the connections state starts to change (READY->NOT READY and vice versa) a necessary

Page 45 / 68

45

amount of failed or passed health checks has to be reached before the state changes completely. This delay is instituted

so as to

mitigate “spikes” in connection availability, but it also extends the time before the backup link can be brought

up or down.

Field Name

Sample value

1.

Health Monitor Interval

Dsb/5/10/20/30/60/120 Seconds

The interval at which health checks are

performed

2.

Health Monitor ICMP HOST

Dsb/DNS/WAN GW/Custom

Where to PING for a health check. As there

is no definitive way to determine when the

connection to internet is down for good,

you’ll have to define a host whose

availability that of the internet as a whole.

3.

Health Monitor ICMP Timeout

½

/3/4/5/10 Seconds

How long to wait for an ICMP request to

come back. Set a higher value if your

connection has high latency or high jitter

(latency spikes).

4.

Attempts Before WAN Failover

1/3/5/10/15/20

How many checks should fail for your WAN

connection to be declared DOWN for good.

5.

Attempts Before WAN Recovery

1/3/5/10/15/20

How many checks should pass for your WAN

connection to be declared UP.

6.

DNS Servers

Auto/Custom

Define custom DNS servers. Has meaning

when you select DNS as your Health

Monitor ICMP HOST.

7.

Backup ICMP host

IPv4 address

This is where the address of an ICMP host,

that will be used to check the health of your

3G backup link, goes. This has to be a ping-

able host.

How do I set up a backup link?

First we must pick a main link: Wired or Wi-Fi, and ensure that the link is working. Configure your WAN settings to use

that link and see whether you have internet access. If the main link is working we can continue configuring our Backup

Link.

Now, go to Backup WAN page and configure the settings to your liking. Click Save and wait until the settings are applied.

Now in the Status -> Network Information page there should be a status indication for the backup WAN. If everything is

working correctly you should see this:

The above picture shows the status for Backup WAN configured on a wired main link. You can now simulate a downed

link by simply unplugging your Ethernet WAN cable. When you’ve done so you should see this:

And, if you plug the cable back in you should, again, see this:
