I have googled and amazoned and I can't find a solution or product for this. Free Republic always comes through for me in answering these type of questions, so here it is. Using an existing Cat5e cable in the wall to each desktop, is there a splitter or inexpensive device that will provide 1-gigabit to the computer and then 100mbit to a VOIP phone off of that single Cat5e in the wall? The original plan was for the phone to provide the VOIP and data to the desktop computer, as the phone has two RJ45 ports on it. And oh, the phone needs to be supplied POE by the Cat5e feed coming into it from the network switch. Therefore, with this said, is there such a splitter or inexpensive device to do this? In other words, I need the 1gibabit speed to the desktop computer and 100mbit to the VOIP phone, but somehow, it would have to utilize that single Cat5e run that is in the wall.
Managed router.
Reverse the polarity.
Assuming that you have a 1 gb network, you will have to share bandwidth. Frankly, your VOIP phone probably needs kilobytes, not megabits, to function well. Relibility (qos) is more important. I think you would have to go with a low end desktop switch with qos on it, but also on the switch feeding your line on the other end.
wouldn’t it be easier and cheeper to get a voip cable modem? then any base station powered off the modem can supply phone for the whole house.
Only one way I can see to do this:
Put a GB switch between the wall and both devices, give up the existing POE, and get a power supply for each phone.
There are power bricks that supply POE for one device.
You’d need a managed ethernet switch.
The plug out of the wall connects to the phone, the ‘uplink’ port on the phone connects to the pc... the PC & the phone each have an IP address... in the switch, you’d allocate bandwidth to each device by IP address on the physical port the wire connects to.
Use a Cisco SG200-08P gigabit 8 port switch. Not too expensive, nice management interface (remember to save your config changes), esaily established QoS for call prioritization and ports 1 through 4 are 48 volt PoE ports. Easy peasy.
Something like this might work. The uplink port will provide 1 gig to the access switch while the regular ports will autonegotiate whatever speed the computer/phone are using. At full duplex on the uplink you should have an effective 2G speed.

Thaw the chicken!
Unless you are at an office where things like CAT scans are transferred by network, or nuclear simulations, you probably aren't. And if you are at an office, let your IT staff handle it.
Just because you have a gigbit interface card in your desktop does NOT mean you are getting that much traffic. In fact, if you have DSL or cable, a 10Mbit interface is more than adequate.

I would not usa a hub. Get a switch. You can get them practically any place even Wal-Mart.

buy a hub/switch that is auto sensing
Thank you and everyone for replying and the ideas that you’ve given to me. Now, the argument that I’m getting from someone is it really worth the effort to get everyone to 1gigabit speed on their desktop computers? About a quarter of the computers at that location are running 100mbit NICs and I had planned on dropping gigabit NICs into the remaining computers with this whole idea. How can I state my case to the higher up that “yes, it is worth the expense and effort to get everyone to 1 gigabit speed on their comptuers” I ask this, because the VOIP phones will provide only 100mbit to the desktop computers.
waynesa98 recommended VOIP cable modem. That would introduce network reliability issues for your phone system. When any node in the series of nodes you connect through to central office goes down, every node after that one goes down. i.e., your VOIP is also down.
Just get a cheap switch from monoprice. I Always try monoprice first.
I’m no expert but you don’t want a hub. A switch is smarter and directs traffic to a specific device.
Your router probably has a 4 port switch already. Usually you can stack them 2 deep.
You set the QOS at the router.
I run one cable from my router switch to the AV area then have a switch for the PS3 and the TV. Another from the router switch to the next room for my PC’s and printer.
Two router connections / 5 devices.
Switches are usually very simple plug and go affairs.
