Technicolor TG582n: Info, Configuration and Usage Options

Hi!

DANT-T and DANT-1 variants

DANT-T and DANT-1 variants

The Technicolor TG582n (quick specs, user guide) seems to be quite popular with ISPs and can be found in branded, sometimes locked*, form throughout. Fortunately, it works really well once properly configured and it is (usually) easy to unlock by flashing it with an unlocked firmware. One thing to take into consideration is that it comes in two main variants, the DANT-1 and DANT-T, with each variant only accepting it's own firmware (unless you are installing OpenWRT).

Firmware Update:

Now, when it comes to flashing the firmware, we need:
(Windows 7 is recommended)

- Thomson Upgrade Wizard 

- User privileges (username and password for user authorized to flash firmware ... for some branded ones we don't need one once router has been reset but for some like O2 we need the user SuperUser with password the Serial Number of router)

- (Unlocked/Generic) Firmware for the variant

Once the firmware has been flashed successfully, one may proceed to configure the router:

Configuration:

These routers can take on many roles and that's what also makes these popular amongst ISPs throughout the world! Using the Configuration Wizard ( thanks to now defunct modem-help.co.uk ) we can choose from templates and with the CLI access (Application Notes provide different advanced configuration scenarios) we can make many changes and tweaks.

Here is an example of configuration of the router as an adsl wifi router:

Here are some screenshots of the router's web interface once configured for our local ISP PTCL:

However, one may use the router as a Wireless Access Point/Wireless Router (IPoE, PPPoE) as well using one of the LAN ports as the WAN port:

Some routers these days auto-detect a WAN connection (on usually Ethernet port 4) when the router has not been configured for a service (like after a reset)! Same is the case with the TG582n as indicated by the sticker below the Ethernet Port 4 as shown below:

So, one may
- reset the router either via the web interface or via holding the hardware reset button pressed via pin for some time
- wait for the router to settle down after the reset
- turn off the router
- plug the LAN cable (for internet) from other router into the Ethernet Port 4 indicated by the sticker
- switch on the router

Note: In order to change settings for the TG582n while functioning as such, one may (temporarily) need to set Static IP (like IP 192.168.1.64, subnet 255.255.255.0 and gateway 192.168.1.254) to login to the web interface!

However, if we want more control over the router, we can use the CLI to convert any LAN port except Port 1 into a WAN (IPoE) port like shown below:

- reset the router either via the web interface or via holding the hardware reset button pressed via pin for some time
- telnet into router at 192.168.1.254
like if Telnet Client feature is installed in Windows OS, then we can use Command Prompt

 telnet 192.168.1.254  

- use the default username and password usually printed on the sticker at the back of the router
usually username will be Administrator with a blank password after a reset
- issue the following commands at the router's CLI (line with # indicates a comment and not a command)

 # Provide Configuration Information  
 env set var=CONF_REGION value=”World”  
 env set var=CONF_PROVIDER value=”Manual Internet over LAN”  
 env set var=CONF_DESCRIPTION value=”IPoE”  
 env set var=CONF_SERVICE value=”Internet over LAN”  
   
 # Disable WAN sensing to prevent it from interfering  
 wansensing config state = disabled  
   
 # Delete other connection settings  
 ppp relay flush  
 ppp flush  
 eth flush  
 atm flush  
 atm phonebook flush  
   
 # Remove Desired Ethernet Port (except Port 1 that cannot be removed) from Ethernet Bridge  
 # In this case, we'll use Port 4  
 eth bridge ifdelete intf=ethport4  
   
 # Add a new logical interface and connect to physical interface  
 eth ifadd intf=ethwan  
 eth ifconfig intf=ethwan dest=ethif4 wan=enabled  
 eth ifattach intf=ethwan  
   
 # Configure the IP Interface  
 ip ifadd intf=Internet_over_LAN dest=ethwan  
 ip ifconfig intf=Internet_over_LAN status=up  
 ip ifattach intf=Internet_over_LAN  
   
 # Enable DHCP on the interface so that we might get an IP   
 dhcp client ifadd intf=Internet_over_LAN  
 dhcp client ifconfig intf=Internet_over_LAN metric=10 dnsmetric=10  
 dhcp client rqoptions add intf=Internet_over_LAN option=dhcp-lease-time  
 dhcp client rqoptions add intf=Internet_over_LAN option=dhcp-renewal-time  
 dhcp client rqoptions add intf=Internet_over_LAN option=dhcp-rebinding-time

 dhcp client rqoptions add intf=Internet_over_LAN option=default-routers  
 dhcp client rqoptions add intf=Internet_over_LAN option=domain-name-servers  
 dhcp client ifattach intf=Internet_over_LAN  
   
 # Enable NAT on the interface  
 nat ifconfig intf=Internet_over_LAN translation=enabled  
   
   
 # Enable the WAN GUI Interface  
 env set var=IS_NOT_DSL_DEVICE value=1  
   
 # Set System Configuration so the LEDs light up properly  
 system config WANMode=ETH WANEthPort=ethif4 defaultconnection=Internet_over_LAN  
   
 # Save the Settings  
 saveall

Here is a video that shows all three configuration options including the PPPoE one (for use behind other dsl/cable/fiber modem):

As stated in video above, if EthWAN PPPoE template is not available on the router itself as one of the built-in templates, one can use the Thomson Configuration Wizard linked-to above with template(s) under "Fiber" section. Zen.co.uk provides some templates as well for fast FTTH connection users that also might come in handy here in case of slow upload speeds.

Tweaks

- Manually changing the DNS Server (like if you want to use OpenDNS, NortonDNS, ComodoDNS, ...)

- Improving wifi performance if one doesn't need b/g modes:

Note: Some options might not be supported by all chipsets! Also, 20 MHz bandwidth might give better performance than using 40MHz in case of congested areas (lots of other wifi access points in the neighbourhood):
