So I was posed with a challenge when Joe asked me to start adding telephones at random to the telephony network…I don’t have a wired network around my house like he does. Nor do I have the ability to just start knocking down walls or running 100 feet of patch cable around to wire up the phones all over the house. So, I had to come up with a solution to “wirelessly” enable IP phones that normally need wires to connect. Here’s how it’s done:
First of all, you need some “tools” to get this to work. Here’s what I have and I’ll explain each component as we walk through:
- One Belkin Mini Surge Protector ($14)
- One TP-LINK TL-WR700N Wireless N150 Portable Router ($25)
- One TP-Link AC TL-PoE150S PoE Injector ($20) – make sure it’s the injector
Once you have the above supplies, you’re ready for the recipe for success…
First – the TP Link WR700N
This device allows the wireless connectivity from the (wired) phone to your wireless network. In order to configure it we have to go through a few hoops, but it’s pretty easy…First, set your “wired” connection on your computer or laptop to the IP Address 192.168.0.200 with a subnet mask of 255.255.255.0. No need for a default gateway, we’re only configuring this little device and then back to DHCP we go. To do that here’s some quick and dirty steps:
- Go to Start -> Run and type “ncpa.cpl” (that should bring up the network control panel)
- Right click on the wired (note wired) adapter and choose properties
- Double click on TCP/IP v4
- Click “Use the following IP Address” and enter the IP address of 192.168.0.200 and the Subnet mask of 255.255.255.0 – NOTE: Make note of the original settings you had as you’ll need to revert back to them after configuring the TP Link
- Click OK a few times to apply the changes
Once you’ve got the IP Address manually configured on your computer, plug the TP Link in to the wall and plug your Computer in to the TP Link. Once you’re sure the TP link has booted successfully, fire up your browser of choice and enter http://192.168.0.254 which should bring up the TP link admin interface. The username and password is admin/admin. Now you need to configure the TP link to be a client.
- After logging in to the TP Link, click “Quick Setup”
- Choose “Client Mode”
- Click the Scan button and wait until it shows your wireless network name
- Click “select” next to your wireless network name
- Change the security settings according to your wireless (most likely WPA-PSK) and enter the password if you have one.
- Click OK to apply the changes (at which time the TP link will tell you it needs to reboot – let it do that)
Now, remove the network cable between your computer and the TP link and then go in to the network settings of your wired connection and set it back (start -> run -> ncpa.cpl -> Ethernet connection -> TCP/IP v4 -> Obtain an IP Address automatically).
Cable it all up
Now that the TP link is configured, go ahead and find where you want to plug this in. Now, break out the Belkin 3 port surge protector:
which not only will enable surge protection but also give you an extra power plug and two USB ports (in case you want to charge say a mobile phone near the IP phone) and plug the TP link in to it first. Presto.
Next thing, you’ll want to plug in the POE Injector:
and then run a network cable from the TP link (plugged in to the electricity via the Belkin) to the POE Injector “Line In” port (next to where the power supply is connected). On the other end of the POE Injector, run an Ethernet cable from there to the IP phone and presto, watch the magic work.
A PoE wireless phone.
Of course, this doesn’t limit itself to just the 1165e, you can do it for any IP based phone that works with PoE technology. Enjoy!
