The Connection/Basic controls aren't “Basic” in the sense that they are simple, but rather that these settings control the most fundamental network configuration of the router and other more specialized Gargoyle features depend on these settings. For this reason, it is best to configure these options first and only change them when absolutely necessary.
The vast majority of the time you will want to select this option, and configure the router as a gateway. When this option is selected your local, LAN traffic is in a distinct subnet and protected from the WAN/internet with a firewall. This option must be selected in order to use firewall features including Quotas, QoS and Access Restrictions.
When this option is selected, the router is put into a very specialized configuration in which the firewall is inactive, and the router connects via a wireless connection to another Access Point. It is possible to connect as a wireless client to another access point while in Gateway mode too, but what makes this configuration special is that the router and connected hosts will be in the same subnet as the upstream access point. Only activate this mode if you're sure you need it.
These controls specify how you connect to the internet. If these options are not set properly you will not be able to connect to anything outside your local network.
Select your connection protocol from this list. Most people will want to connect via the DHCP (wired) option, which is the default. If you have an ADSL connection you should select PPPoE, and put your ADSL modem in bridge mode. Below is a description of all connection options:
Set a custom MAC (hardware) address for the WAN interface. Note that some router models do not support this feature. If your router doesn't support this feature, nothing bad will happen if you try to activate it, it just won't set the MAC as you requested.
The Maximum Transmission Unit (MTU) is the size of thelargest unit of data, in bytes, that is passed over the network. 1500, the default is usually a reasonable value, but if you are connecting via ADSL it is often a good idea to set this to 1470.
These settings control the Local Area Network (LAN), which consists of the router and the computers/devices that connect to it.
This is the IP (IPv4) address of the router on the local network. 192.168.1.1 is the default. Router IP addresses should be in the 192.168.0.0/255.255.0.0, 172.16.0.0/255.240.0.0, or 10.0.0.0/255.0.0.0 subnets, which are reserved for local networks.
The LAN subnet mask. The default is 255.255.255.0. It doesn't make much sense to use a larger subnet mask, as a subnet mask of this size contains addreses for 254 hosts, far more than any router running gargoyle can handle by itself.
These controls are slightly different depending on whether you have a router running the newer Gargoyle 1.5.X+ series of releases, or the older versions. However, in both cases, Gargoyle will, by default, serve DNS requests from your default ISP DNS servers.
In older Gargoyle releases you can enter the IP addresses of your preferred DNS servers if you do not widh to use ISP servers.
In newer Gargoyle releases, in addition to specifying custom DNS servers individually, you can specify that you want to use either the Google DNS servers, or those provided by OpenDNS.com from a dropdown box. This means that if you wish to use one of these alternate servers you will not need to enter the IP addresses manually. If you use the OpenDNS filtering service you should select the OpenDNS servers from this dropdown, and then configure your account in the Dynamic DNS section so that it gets updated properly. On newer releases that will allow the resolution of specialized top-level domains. While most people will not need this feature, leaving this checked does not inhibit performance, and will permit access to websites you otherwise would not be able to resolve.
By checking this box you can force all clients connected to the router to use the DNS servers you specify above. Under normal circumstances clients can configure alternate DNS servers if they wish. However, if you check this option all DNS requests will be redirected to the specified servers. This is especially useful if you are using the OpenDNS filtering service.
These settings control the wireless capabilities of your router.
This option specifies how the wireless network should function. Most users will want to configure the router as an Access Point (AP), which means that the router will provide a unique wireless network to which clients can connect.
The possible options are:
This option, which is only visible on wireless N routers, specifies the wireless specification and the frequency band to use on routers capable of dual band operation.
The possible options are:
This option is only visible on wireless N routers. It specifies whether to use the narrower 20MHz channels or wider 40MHz channels. In order to get maximum throughput you will need to use wider channel width, but this can result in conflicts/interference if there are a lot of wireless networks in your area. It is best to leave this setting at 20MHz if there are a lot of other wireless networks in your area, but if no other networks are around 40MHz will provide faster wireless speeds.
You probably don't want to change this setting. Seriously… move along. By default, Gargoyle/OpenWrt enables the highest transmit power permitted by your hardware. Due to hardware differences the actual value reported in the interface may be slightly off… but the highest power possible is consistently enabled, anway. The only reason to change this value is if you want lower transmit power than what is possible. If you want better performance, buy a bigger antenna or try different wireless channels where there may be less interference. Tweaking this setting will not boost the performance of your router.
These settings allow you to block or white-list wireless clients by MAC (hardware) address. Note that it isn't too dificult to clone MAC addresses, and therefore MAC filtering isn't a good substitute for proper wireless encryption, but rather should complement it.
These controls are only visible when the router is configured as a wireless Access Point (AP).
The name of the wireless network.
The channel (frequency) this network should operate on. No channel is any better than any other, but performance will be lower if there are neighboring networks that use the same channel. If there other wireless networks in your area you may want to try different channels, as you may get better performance on some channels than others due to interference.
It is strongly recommended that you encrypt your wireless network, otherwise anyone walking down the street outside will be able to connect. WPA2 PSK is the most secure, widely used encryption algorithm, and it is strongly advised that you configure your network with this encryption method.
The available options are:
The password for your wireless network, only visible if you hve enabled encryption.
When people scan the local area for wireless networks, do you want yours to show up? It is recommended that you leave this enabled so that your clients can scan for local networks find yours, and connect. If you disable this, you will have to manually enter the SSID (network name) on all clients – it won't be automatically detected. This option is enabled by default.
If this is enabled, wireless clients will be able to interact with the router, but not other clients that have connected wirelessly. This option is disabled by default.
This is the name of the wireless network to which the router should connect
You can scan for wireless networks in your area if you press this button. You will be able to detect the Name/Channel/Encryption/Signal Strength of local networks automatically, and select your preferred network from a drop-down. This allows you to avoid entering the information manually.
The wireless channel (frequency) the AP to which you are connecting operates on.
The type of encryption the AP to which you are connecting is using
The password required to access the AP to which you are connecting. This field is only visible if the AP to which you are connecting uses some type of encryption.
