The Logik IR100 radio ships in factory default state with DHCP function fully enabled

In majority of situations, you should not need to change this setting.  However, if you are experiencing difficulties connecting to the internet with errors such as 'DNS Servers Invalid', then you may need to manually configure various network settings on your IR100 as described below.

 

If you are seeing Wireless error messages such as 'Wireless error 13', do NOT follow the steps below to try and resolve them.  It has no relevance to wireless security issues.

 

This is a 'dumbed down' guide so I make no apologies for some of the 'shortcuts', assumptions and guesses.

 

What is an IP address?

For every device on your home network to be able to connect to the internet, it requires a unique IP address.  An IP address is analogous to a residential address.   Your postman has no difficulty (most of the time) delivering mail to you and your neighbours because you all have unique addresses.

The DHCP service offered by all broadband routers takes the grief out of setting up each of your networked devices (eg. PC)  to be able to connect to the internet.  It performs this operation  automatically for you provided DHCP function is also enabled on your devices (eg. PC, IR100)

If your Logik experiences errors such as 'DNS Servers Invalid', and you do not wish to change or cannot upgrade your router, then you will need to switch off DHCP on the Logik IR100 and configure it manually.

You will need to obtain the following information before you can go about configuring your Logik IR100:

  1. IP address
  2. Subnet mask
  3. Default gateway address
  4. At least two DNS server IP addresses as supplied by your ISP.

If you have a Windows XP computer on the same wireless network, you can obtain some of the information you require as follows:

 

A DOS command window will appear.  Now type in the command                   ipconfig /all            and press the Enter/Return key

From the above screen, we can immediately obtain the following information about our network:

            Subnet mask in this example is                255.255.255.0

            Default Gateway is                                 192.168.1.1

(If you are still using Windows 98 or Windows ME, try using:  winipcfg.exe)

 

Next, we now need to assign a suitable and unique IP address for our Logik IR100 radio.   Most home networks are unlikely to have more than a few networked devices (PC, printer, games console etc). 

In the above screen, you can see the IP address of my computer is 192.168.1.64.  I also happen to know that my broadband router assigns IP addresses starting at 'x.x.x.64' and steps upwards.  eg. my other PC would be 192.168.1.65 and so forth.     

The only digit I can edit is the one on the end of the IP address and I need to find a number which will not be used or issued by my broadband router..  ie.  I can change the '.64' to any other number I wish between 1 and 254.

I don't have more than a couple networked devices at home so it is reasonable to assume if I randomly pick an IP address that is at least 10 higher or lower than what my PC is presently using, I'm unlikely to cause any problems.   eg. I could choose to assign the IP address 192.168.1.55 or even 192.168.1.75 to my Logik IR100 knowing it should not conflict with any other device on my home network.

 

Important: the IP address ranges you will be wanting to use MUST begin with '192.168.x.x', '10.x.x.x' or '172.16.x.x'.  If your computer's IP address does not begin with any of these numbers, you may have a non-standard router configuration.  Do not proceed any further.  Most likely your public IP address as supplied by your ISP has been passed through to the computer you are happen to be using.  Most router manufacturers refer to this as DMZ mode.  If you have a second PC, check the settings on that computer.

Important:  Do NOT pick an IP address that is the same as your default gateway!  ie. My default gateway is 192.168.1.1, so using IP address 192.168.1.1 would be a big mistake in my example!

 

A list of commonly used IP addressing schemes for popular makes & models of routers can be found at the end of this page.

 

What is DNS?

DNS is basically analogous to a phone book.  You know the name of the person you want to call but you don't know their phone number.  DNS is used to convert human-readable web addresses (eg. www.yahoo.co.uk)  into IP addresses.  Your internet provider will own a pair of DNS servers they would like you to use.  The DNS servers provided by most ISPs are usually quite reliable but if you have any doubts, there is usually nothing from stopping you using alternative more reliable DNS servers belonging to another ISP.... 

 

So, the final piece of information I require are the DNS servers IP addresses.  You ideally need to use the DNS server IP addresses which your Internet Provider supplies to your broadband router, but you may wish to use alternatives, such as the OpenDNS name servers.    You may find it on their website help pages.  This information may also be provided in the above Windows XP screenshot BUT is NOT necessarily provided in all cases.  In general, your ISP's DNS server IP addresses will NEVER begin with  '192.168.x.x', '10.x.x.x' or '172.16.x.x'.

So if you see a DNS server with IP address such as 192.168.1.1 which happens to be the same as the 'Default Gateway' IP address, this is NOT the DNS server IP address you will wish to use - especially if your Logik encountered the 'DNS Servers Invalid' error message which you are trying to resolve.

Your broadband router should have this information available to you. On my Linksys router, I have to look under the 'Status' menu, there buried away amongst other information are the IP addresses of my ISP's two DNS servers, which happen to begin with '212.xxx.xxx.xxx'.

 

In summary, using the above example, I now have my four pieces of information:

  1. IP address:            192.168.1.55
  2. Subnet mask:         255.255.255.0
  3. Default gateway:    192.168.1.1
  4. DNS servers:          212.x.x.x       &     212.x.x.y                    

I have not provided true DNS server addresses for my ISP, because I do not wish to swamp their DNS servers with connections from all Reciva Radio owners following these instructions on this webpage.  Of course you can use the DNS servers from any other ISP or which are publicly available if you believe your own ISP's DNS servers to be unreliable.

Alternatively, you can use OpenDNS nameserver IP addresses 208.67.222.222 and 208.67.220.220, obtained  from this web page.   

 

Configuring IR100

Armed with all the information I need, I can now configure my Logik IR100.

Please note: the screenshots shown below are from IR100 for the newer v257-a-421-a-057 firmware.

 

           

 

           

 

           

 

           

 

           

 

              

               

 

           

 

           

 

           

 

                

 

           

 

                

Do NOT use address beginning with '192.168.x.x', '10.x.x.x' or '172.16.x.x'.

 

           

 

                

            Do NOT use address beginning with '192.168.x.x', '10.x.x.x' or '172.16.x.x'.

           

           

 

You have now completed the manual configuration.

 

You can check your settings through the 'View Config' menu (2nd option in this list):

           

Use the Scroll knob to scroll through each of the settings.  

 

Switch off and then on the Logik at the mains wall socket.  Hopefully it will now connect to the internet.

 

If you still see 'DNS Server invalid' message and you are using the DNS server IP addresses supplied by your ISP, then try using alternative DNS nameservers.

 

My Linksys WAG354G wireless router has a tendency to freeze/hang in operation around once or twice a fortnight.  When that happens, wireless connectivity is lost and no LEDs on the router flicker which they would normally do if the router was working correctly.   Rebooting the router restores normal operation but I have to remember to go around and reboot all my networked devices including the Logik so the router can build up a true list of DHCP assigned IP addresses. (The WAG354G's DHCP service doesn't allow one to reserve IP addresses against MAC addresses. The technically savvy readers among you will know what I'm talking about).   To avoid having to power cycle the Logik every time I reboot my Linksys router, I'm hoping by configuring my Logik with a static IP address, I won't need to reboot the Logik so often.

I  replaced the Linksys with a BT 2700HGV router in May 07 onwards.

If you have firmware v257-a-421-a-057 installed, I've observed what appears to be a bug if you try to change from using a static IP address back to using DHCP.  With previous v255-c-158 firmware, one could go into the 'Edit Config' menu and re-enable DHCP.  The radio will then pick up an DHCP IP address from the router, but it now won't connect to the internet with the newer firmware.   I subsequently ended up having to perform a factory reset and Scan for Networks to get around the problem.  (Perhaps I didn't need to do a Factory Reset, but I was in a hurry at the time) 

 


OpenDNS blocks some websites

(New 10 Mar 2010)

I use static IP addresses on all my Reciva radios and they are also configured to use OpenDNS servers.

The other day, I encountered a strange problem where the radios could not connect to a particular radio station which uses Real Audio streaming.   The WMA version of the same station worked just fine.

My PC was able to connect to the same Real Audio stream without issues so this led me to suspect it was a DNS issue.  (My PC uses my ISP's regular DNS servers)

 

After reconfiguring my PC to use OpenDNS servers, I was unable to connect to the radio station's website or to their WMA and Real Audio streams.

 

After further googling, it transpires that OpenDNS offers filtering services to their customers. (I am not an OpenDNS customer btw)  I had restarted my router/PPP session with my ISP the previous day, this resulted in a new public IP address being assigned to my router, but this new IP address must be evidently known to OpenDNS.

 

Restarting my PPP session to acquire a different new public IP address resolved the problem with OpenDNS.

 

 

 


Known cases of routers requiring the IR100 to use static IP address

 

A reader who is with AOL UK broadband, and myself have encountered this issue with the Speedtouch 585 wireless router.  Configuring the IR100 with a randomly invented IP address of say 192.168.1.50, subnet mask 255.255.255.0, default gateway 192.168.1.254, and your ISP's DNS servers is proven to work. 

A reader of an AE radio who is with AOL broadband, reported their AE radio had been working fine until Feb 08.  This may have coincided with changes involving CarPhoneWarehouse switching AOL users to new CPW host servers. Use of static IP address and OpenDNS name servers resolved the problem.

 

If your router is not listed above and you had to configure your Logik IR100 to use a static IP address because you previously encountered the 'DNS Servers Invalid' message, feel free to email your IR100 IP address, subnet mask, default gateway, make & model of router, router firmware version (if known), IR100 firmware version, the name of your ISP, and your Reciva community forum name (unless you wish to remain anonymous).  My contact email address is on the main page.
