fixed : use one printer in two networks at the same time

Question :

I have a network printer on my (private) network that I would like to make available to the people on my AirPort Guest Network, but I don’t want guests to access my private network.

Is there a way to do this ?

 

Answer :

There are options to do this, but it can’t be done the way you would find most elegant probably… the problem is the restriction in AirPort Guest Networks that users can’t connect to each other, so adding the printer to the AirPort Guest Network won’t make it available to any AirPort Guest Network user.

On the other hand, an other restriction on most network printers is that they only have one Ethernet-card that is shared between the UTP-cable port and the WiFi connection, so the cable-connection and the WiFi-connection will always have the same IP-address, making it impossible to connect the cable to your private network and joining the Guest Network using the WiFi-connection at the same time…

Your best option is to connect the Ethernet/UTP-cable and/or the printer’s WiFi to your private network and creating a separate network to be used as a Guest Network to which the printer can be connected using it’s USB-cable. Since you will need an extra wireless router or an extra (secondhand) AirPort Base Station or Time Capsule to create this separate Guest Network, you can plug the printer’s USB-cable into that wireless router / AirPort Base Station / Time Capsule.

You could also use a printer server, if it isn’t possible to connect the printer’s USB-cable into the wireless router / AirPort Base Station / Time Capsule. You can find relatively cheap print servers on Amazon.com, Amazon.co.uk or Amazon.de

Regarding the setup of your networks, you will probably be best off doing it like this :

  • set your internet modem in router mode (if you would set it in bridge mode, you wouldn’t be able to connect two separate networks behind it)
  • connect both routers (or AirPort Base Station or Time Capsule) to the internet modem
  • setup one router (or AirPort Base Station or Time Capsule) to create the private network and private WiFi network
  • setup the other router (or AirPort Base Station or Time Capsule) to create the Guest Network and Guest WiFi Network
  • make sure that the IP-ranges issued by both routers are completely different (to prevent easy connection from the Guest Network to your private network (and the other way around)
  • if any of your routers give a “Double NAT” error, just ignore it

That’s it !

the only downsite is that having such a complex network setup with multiple routers will have negative influence on your (internet) connection speed ; this difference in speed will probably not be very big if you have few devices connected, but if you have a lot of devices connected that also use a lot of bandwidth (like video streaming) you will probably have slower internet speed than you used to…

enjoy !

fixed : setup LogiLink WL0083 as WiFi-to-ethernet-bridge

Question :

I have a Philips BluRay player which has the option to connect to the internet (for things like YouTube and Picasa), which I think would be interesting to every once in a while.  The BluRay player has two options to connect to the internet, either using an ethernet network cable or using the special Philips WiFi-to-USB-dongle that is very expensive.

Problem is the BluRay player is next to my TV (and my AppleTV), but I do not have an ethernet cable connection there, only WiFi… (and my AppleTV cannot share it’s WiFi connection through it’s ethernet port…)

My first thought was to use an Apple AirPort Express and connect it to the BluRay player’s ethernet-port to use it as a WiFi/AirPort-client… but since I do not have an AirPort Express (yet), buying one would even be a more expensive option than buying the official Philips WiFi-to-USB-dongle…

On the other hand… I do happen to have a mini/portable WiFi-router (a LogiLink WL0083) lying around, which should be able to act as a WiFi-to-ethernet-bridge also…

But… even after several tries, I did not succeed in setting the WL0083 up properly…

Any idea how that should be done ?

Answer :

Yes !

Actually it’s rather simple, you just have to setup the LogiLink WL0083 as “Client+AP” and use the setup-wizard of the web-interface, but there are 3 things to know :

-1- the default IP-address of the LogiLink WL0083 is 192.168.2.1 so you need to be sure that the network you want it to connect to does not use the 192.168.2.0 to 192.168.2.255 range of IP-adresses (so you might have to reconfigure your ‘entire’ network to use the 192.168.3.1 to 192.168.3.255 range…)

-2- to make it a “Client only” instead of a “Client+AP”, you should set SSID broadcast to “Hidden” and leave the additional (extender) SSID in default “Logilink” and “Disabled”

-3- and… when finishing up, do not forget to change the IP-address of your Mac’s WiFi and ethernet connection back to “DHCP”

in a step-by-step guide, that would be :

– make sure your WiFi network is not using the 192.168.2.0 to 192.168.2.255 range of IP-adresses (if it does, reconfigure your network router to use another range of IP addresses, and reconfigure all clients in your network that use Static IP addresses)

– then unplug your ethernet cable from your regular network

– disconnect from your regular WiFi/AirPort-network

– connect the LogiLink WL0083 to your Mac using an ethernet cable, and connect it’s USB-cable to a powered USB-port (e.g. on your Mac)

– then press the small “WPS/Reset”-button on the WL0083 for about 5 seconds (to reset it)

– then, on your Mac, go to Apple Menu (Apple icon top-left on the screen) –> System Preferences –> Network –> Ethernet and change it to “Using DHCP with manual address” and type the IP-address 192.168.2.100 in the input field

– then open Safari and type 192.168.2.1 into the URL-field ; for User Name and Password type “admin” (both the same)

– now the LogiLink web interface should open

– click on the “Client+AP” tab, then “Setup Wizard” on the left, followed by “Next” on the left

– on the next screen, start by clicking on the “Scan”-button, and wait for the list of SSIDs of local WiFi/AirPort-networks to appear

– then select your WiFi/AirPort-network from the list

– everything will then be automatically filled out, apart from “Pass Phrase:”, there you should type your WiFi/AirPort-password

– then click “Next”

– in the “Wireless Basic Settings”-screen that opens, set “Network Mode” to “11b/g/n mixed mode”, leave “SSID” as it is (probably “Logilink”), set “Broadcast SSID” to “Disable” and leave the rest as it is automatically set

– then click “Next”

– in the “Wireless Security Settings”-screen that opens, set “Security Mode” to “Disable”, and leave the rest as it is

– then click “Next”

– in the next screen click “Apply” and the WL0083 will reboot

– then, on your Mac, make sure that you are NOT connected to a WiFi/AirPort-network

– then go to Apple Menu –> System Preferences –> Network –> Ethernet and change it to “Using DHCP”

– then, in Safari, manually type the URL of any existing website that you do not often visit (e.g. the website of the city you live in) and see if it loads, to check if the WL0083 is properly configured as a WiFi-client on your network

– then disconnect the LogiLink WL0083’s ethernet and USB cable from your Mac

– so, go over to your BluRay player, and connect the LogiLink WL0083’s ethernet cable to it and connect the USB cable to a powered USB-port (or USB-poweradapter)

– now try and see if your BluRay player can use it’s internet services

– if your BluRay player needs any additional configuration, just set it to “ethernet” and “DHCP”

Enjoy !

Note #1 : the LogiLink WL0083 supports WiFi-N only at 150Mbps speed, even though the normal maximum speed of WiFi-N is 300Mbps (just like Apple’s implementation of WiFi-N in AirPort), most of the time you will probably not notice any decline in quality, but you might if you’re a heavy user…

Note #2 : if you want to adjust something small on your LogiLink WL0083 after you’ve configured it, you just need to temporarily switch your ethernet-connection from “Using DHCP” to “Using DHCP with manual address” and 192.168.2.100 as the actual IP-address ; then you can login to the LogiLink web-interface at the 192.168.2.1 URL (and do not forget to change back to “Using DHCP” afterwards)

fixed : 5V 4A car adapter for Samsung Optical SmartHub SE-208BW

Question :

I have a Samsung Optical SmartHub SE-208BW (all-in-one : WiFi-DVD player, media streamer,  WiFi-router and DVD+R burner), and since it is capable of streaming DVDs and HardDisk content to my iPhone/iPad using the Samsung SmartHub iOS-app, I thought it would be a great idea to use it in my car also.

However, if I power it using the USB-cable that comes with the SmartHub, it is limited to not act as a WiFi-device. So… I need a ‘dedicated’ car-adapter for it…

But… the power needed is 5V and 4A minimum… that’s a really rare combination… and Samsung does not sell any car adapters for the SmartHub, neither do they have any recommendation on a good solution…

What options do I have ?

Answer :

The Samsung Optical SmartHub SE-208BW is a rather unique piece of equipment. Combined with an iPhone/iPad and the SmartHub-app, it is a really versatile solution …if you keep in mind that it still has some little flaws…

If you ask Samsung how to power the Samsung Optical SmartHub SE-208BW in your car, they will recommend using a cigarette-lighter-to-220V-transformer…

…that’s a stupid ‘solution’, since transforming from 12V to 220V and back to 5V is both a complete waste of energy resources and it will drain your car battery…

So… after elaborate search and testing, I’ve found a ‘real’ car adapter solution for the SmartHub ; you should create a car-adapter yourself consisting of these three parts :

1- a USB to 5V DC Barrel H power cable like this one :

USB to 5V DC Barrel H power cable

2- a USB Y-connection cable (2x USB-male to 1x USB-female) like this one :

USB Y-connection able

3- a 5V 4.2A dual-USB car adapter ; at this moment, there is only one product like this that actually works :

5V 4.2A dual-USB car adapter

If you join these 3 parts together into, you’ll have exactly the car adapter you need for the Samsung Optical SmartHub SE-208BW.
