Sharing wifi to ethernet port troubles

I am trying to share my wireless internet connection (from a public wifi spot) to my ethernet connection on my mac. I get the wireless connection just fine on my iMac and connect to the internet directly from there, so I know that's working.
I have turned on the internet sharing option in the control panel and told it to share from the airport card to the ethernet port. However, when I plug a device (like my linksys router) into the the ethernet port and try to connect to the internet via that route it doesn't work. There is no connection it seems.
What have I done wrong? Is there some setting I am missing?
Thanks in advance.

I had the same problems with this too. Try changing your existing network to something other than 192.168.2.x (such as 192.168.1.x, or 0.x, or 3.x, or 10.x.x.x). Turns out that Tiger hard codes the 192.168.2.x network number for creating the new network, and it conflicts with the existing, to be shared network. Figured this out while searching for how to manually envoke natd, and am still annoyed that there was not even a warning about this.

How can I troubleshoot Internet Sharing (wifi to ethernet)?

Hi hi everyone!
Any idea how to troubleshoot wifi/ethernet Internet Sharing? I use to network a media player (like an AppleTV not made by Apple) and recently it stopped working. Luckily I have two macs in the house to shoot the troubles.
I have an iMac running Leopard 10.5.5 and a Powerbook running Tiger.
I have tried sharing both ways (imac wifi » powerbook ethernet and powerbook wiki » imac ethernet) but am only able to get an IP from the DHCP server (Airport Extreme N base station). I am not able to get on the web (google search, etc).
Where can I look to see what's not working?

Hi Ryan Feeley-

Ethernet port troubles

Hi folks.
I've recently bought a refurb Mac Mini to supplement my iBook. Everything's fine and I'm fully up-to-date, except that the Ethernet port seems to be dodgy. The Mac Mini loses connection with my cable modem regularly, though it will recover connection if I remove and reconnect the cable or generally waggle it around.
I can't believe this is a problem with the cable, as I have used it without any problems on two other computers. I was just wondering if anyone's heard of problems like this before with the Mac Mini and if there might be any precedent for hardware faults of this nature?
Thanks.

I'm also having trouble with my mini on the ethernet. The problem that I'm seeing is that it seems to be doing very strange things with its Ethernet MAC address -- Everything on the mini seees the MAC address as 00:0d:93:7b:cf:a6, but it shows up in the router DHCP client tables as that and some invalid value that changes each time I reboot the mini. The DHCP service on the router is dutifully providing an IP address to both the real MAC address and the wierd one, but the mini only responds to connections at the IP address assigned to the weird one. The current weird IP address displays on the router (A D-Link DI-524 running the latest firmware available) DHCP clinet list as "6D696E69", which is not 6 octets (the real MAC address display as "00-0d-93-7b-cf-a6" in the same list). Previously (before the most recent reboot), the weird address was showing up as "6D697373696E6D", which is also not 3 octets -- it's 7 octets.
I saw similar behavior with a LinkSys RT31P2 router, though it never showed me the odd formatting, it just showed somewhat random MAC addresses. I thought it was a problem with that router, so I put the D-Link in its place, and now I'm seeing what I've described. With the Linksys, I'd have to reboot the router any time I rebooted the mini, otherwise I could not connect to the internet through the router.
I've been having this problem with my wired LAN since I got the mini, but I was blaming the router. Now I'm pretty well convinced that there's something amiss with the mini's ethernet port.

Apple TV 2, Home Sharing, WiFi and Ethernet Problem

Equipment:
- Three 2nd Generation Apple TVs
- AirPort Extreme
- MacMini running current version of iTunes
Problem/Situation:
I have a Mac Mini set up as a dedicated media server running the current version of iTunes via Home Sharing. I have three 2nd Generation Apple TVs in the house streaming media from this server. All three Apple TVs are up to date. The network router for the system is an AirPort Extreme. All software updates have been performed, and this is a long term problem (has existed for some time, did not just appear.)
Two of the Apple TVs connect flawlessly, but one of them is "quirky"
I have recently moved and as a result the configuration has changed a bit, the problem existed both before and after the move, and the two configurations may shed some light on the problem. In the old configuration the whole house had hardline ethernet available throughout the house, all connected to the AirPort Extreme. All of the Apple TVs worked fine except for the "quirky" one, which refused to connect to home sharing via an ethernet connection, but worked fine via a wifi connection (the other two Apple TVs worked via ethernet.) My solution was simple - unplug the ethernet cable and connect via WiFi.
However, in my new household there is currently no ethernet run, so all connections are via WiFi. As before the same two working Apple TVs connect just fine, but now the "quirky" Apple TV cannot connect to Home Sharing. I have reset the Apple TV to factory defaults, to no effect.
I have not yet run a test ethernet line to the Apple TV, but I theorize that it would work. My working theory is that the quirky Apple TV cannot be on the same type of network as either the server (since the problem exists even if the other Apple TVs are in sleep mode.)
So far I have not found any articles that are on point to this problem, and I don't think this is a known problem. I would love to find a solution to this problem that does not mean that I have to run a ethernet line through the house. Hopefully someone will have some insight to this issue.
Thanks,
Ken

**** UPDATE ****
So this morning I decided to test my theory.
I connected the "quirky" Apple TV to the Airport Extreme via an Ethernet cable running down the hallway. The device was able to get an IP address, reach the outside world, but no joy on connecting to Home Sharing being served from a computer connected via wifi to the same router. (Hmm, theory fail - strike one.)
Next I decided to run this cable to a ethernet switch connected to the serving computer (with a self generated IP). This time the Apple TV could not see the outside world (as expected), but could still not see the Home Sharing network either. (Hmm, theory epic fail - strike two).
Considering my testing now complete, I disconnected the ethernet cable and allowed the Apple TV to once again connect to the WiFi network (the configuration I started the day with.) This time not only did the Apple TV connect to the outside world, but it found the Home Sharing network, and all worked well. (Swings, and connects to a long fly ball to deep center - stay tuned to see if it is a home run or something else.)
While the system is now working as I would like - I can not say that my confidence is high at this point because I did not really change anything - I simply stirred the pot.
Very bizzare!

Sharing internet through ethernet port

I'm sharing internet through my ethernet port to my other computer but so far it appears that it only works for web browsing. Is their something I can do (open a port or something) so the other computer can use the shared internet for more than just web browsing, like use ichat, Mail, or Dashboard?

Yes the firewall is on. Do I have to turn it completley off or can I just open a couple of ports?

Cisco RE1000 WiFi extender ethernet port question

Good morning - I have a RE1000 WiFi range extender which is unable to reach the far end of my house, an old barn with a thick stone wall in the middle (& the ADSL line enters at the other end of the building). I have tried various extender locations on both sides of this internal stone wall without consistent success.
A simple solution - IF the ethernet port is two-way - would be to run a 100ft long exterior Cat5 ethernet cable from my existing router to the far end of the house, into the RE1000 as its feed (as opposed to the RE1000 trying to pick up the WiFi signal from the router) & then any WiFi device at that far end of the house could connect via the WiFi signal from the ethernet-powered RE-1000.
Will this work, ie. will the RE1000 accept the ethernet signal as its source and transmit it onwards via its WiFi capabilities (or is the RE1000 ethernet port's only purpose to transmit wirelessly-received signals to a wired, non-WiFi-capable device ?) ?

The use of Ethernet port in RE1000:
"> Ethernet (green) Using Ethernet cables (also called network
cables), this Ethernet port connects Ethernet network devices
to your wireless network.
The green light turns on when an Ethernet device is connected
and active on this port. The light flashes when the extender is
sending or receiving data over the Ethernet port.

Ethernet port trouble

hi there
I have recently upgraded my ibook 500 MHZ to OS 10.2.8 i now want plug in to a cable modem using the ethernet port. However I don't seem to be able to make the connection, infact i think the ethernet port has become faulty, It displays in the system profile ok, but won't see printers or the cable modem. Is there any test i can do the check if the port is functioning?
thanks

Look in your
Applications > Utilities
folder for "Network Utility" It will show you the state of the networkable ports, tell how many packets have come and gone, and allow you to "Ping" the IP address of the broadband modem or the router beyond it (the IP address provided by your ISP).
How you set up the
System Preferences > Network > (your Ethernet port)
depends entirely on your ISP. They may give you a manual address, ask you to use DHCP, or require you to use PPPoE.
If you are trying to see an Apple LaserWriter, you may need to be sure AppleTalk is turned on for the active network interface.
The physical Ethernet ports on really early iBooks were pretty flimsy, but by the time the dual USB 500 came out, they should have improved significantly.

Screen sharing - wifi and ethernet

I have a Macbook on an Airport-based network and an iMac on an ethernet network on a Netgear router. The Airport is plugged into the Netgear router. I would like to get the wifi-based Macbook to control the screen of the ethernet-based iMac. I have followed all the instructions as far as I can tell, but have so far had no success. I can connect the two using the Finder 'Go' option but not control the screen. Anyone got any tips for setting this up?

Have you tried Finder -> Go -> Connect to server -> vnc://imac.address
I am concerned about the fact that you mention "Airport-based network" and then in the same sentence "Netgear router".
That makes me think (as I assum cabeandsuz) that you have both a Netgear router *AND* an Apple Airport Extreme or Airport Express router runnin in your home.
If you do NOT have an Apple router, then ignore the following:
If you do have both Apple and Netgear routers, then you may have 2 active routers in your home, and the Bonjour auto discovery protocols will NOT travel between routers. So your MacBook on the Airport Extreme or Airport Express router would not be able to see the iMac on the Netgear router, and the reverse would be the case because you are crossing a router boundary.
Airport Extreme and Airport Express routers can be put into "Bridge" mode via Applications -> Utilities -> Airport Utility -> Internet -> Share an internet connection -> Bridge. (or something like that). That would turn off the routing fuctions in the Airport Extreme or Airport Express and turn it into just an ethernet to WiFi bridge extending the existing Netgear router's subnet, so everyone is on the same subnet, and Bonjour protocols can access all your home computers.

Sharing Ethernet port

I'm on a wireless network and have a SIP phone in the office: On my, soon to be retired, Powerbook G4 (in OS 10.2.8) All I had to do to get the phone to work was check share this internet connection in the network control panel. The mac then established itself as a DHCP server for the ethernet port and routed my phone traffic over the wifi (airport)
On my MacBook Pro (OS 10.4.9) the options have changed slightly: The options seem to make perfect sense: I am sharing my connection from the Airport card to the ethernet. only problem: It doesn't work. I don't have the firewall turned on (although I'd rather change this) just to avoid a conflict. What am I doing wrong?
PS: I seem to have way too much routing going on by what netstat is reporting but then I can't really read NetStat reports; This is not so much a case of being IP ignorant (although I'm no Guru) as it is not having any reference materials for netstat codes. Can someone direct me on how to read a netstat report?

The portable has to hand out DHCP addies to anything that wishes to share it's connection, it simply must.
The G5 will not be getting a DHCP addy from the Wireless LAN via Ethernet, the portable is the go between, and it's the only one that needs to get an addy from the router.
A possible scenario...
Portable gets IP of 10.0.1.2 from Router 10.0.1.1, G5 will have a Router setting of 10.0.1.2, (the portable), and gets a pseudo IP of 10.0.2.3 from the pseudo Router 10.0.1.2, (the portable), with the portable translating where the two different base packets go to/from.
"Is there anyway to see if THE PORTABLE is a DHCP server ?
Yes, if the Portable is set to "share" it's Internet Connection, then it will be a DHCP Server, pure and simple.
And can it be truned off?
Yes, very easily... turn off Internet Sharing".
Is there a GUI to manage DHCP or is it throught config files?"
Depends what/how you want to manipulate them, but the only thing you need to do with it ... is GUI via Sharing & Internet.
The G5 just needs to Join the portables advertised network to get connected, iirc.

Network Configuration Window Freezes When USB NDIS Internet Connection Sharing and Ethernet Port Are Used Simultaneously

Current Setup:
Asrock Extreme 4 Z77 mobo with built-in Broadcom NetLink (TM) Gigabit Ethernet. Windows 8 Pro. Intel i5-3570k (using onboard Intel 4000 HD Graphics). RAID0- 2 OCZ Vertex 4's.
I will refer to this setup as my tower.
The Ethernet port works fine by itself. When I use wired tethering with my Android phone (Droid 4 running on 4.0.4 Ice Cream Sandwich), it works fine when nothing is connected into the Ethernet port in the mobo.
The issue arises when I try to connect both simultaneously. The network configuration window in windows basically freezes and I cannot really navigate it without a ~60 second delay at best.
I would like to be able to accept the internet from my Android via a USB tether and either bridge the connection or use the internet connection sharing service to route traffic through the unused Ethernet port on the mobo (either to another computer/xbox
or more desirably a switch/router to spread to the entire home network). I have extensively researched the issue of Windows 8 become slow and unresponsive when I attempt to do this and I have not found anyone with the exact problem. I am able to
do both the MAC bridge miniport (bridge 2 connections) and Internet Connection Sharing though a Windows Vista (home premium) Laptop I have. The difference between the laptop and the tower I am try to do this on is the laptop has a WIFI and Ethernet connection
while the tower only has the on-board Ethernet.
Do I have all the necessary equipment to accomplish this, or do I need to buy a PCIe WIFI card? If so could I get away with just getting a USB WIFI dongle?
Any help would be very appreciated.

I had the same problem and came here by searching.
Per Rosengren's method solved the problem, but he didn't say how to do it, so I'll try to explain step-by-step for anyone that may venture here.
Open Device Manager (right click on Computer > Manage > on the left side, under System Tools choose Device Manager)
Choose the problematic device in Network Adapters (for me it's called HTC Remote NDIS based device)
Right click on it and choose Update Driver Software...
Click Browse my computer for driver software
Click Let me pick from a list of device drivers
Uncheck the box Show compatible hardware
For the manufacturer, choose Microsoft Corporation
Now you will have two options:
- Remote NDIS based Internet Sharing Device
- Remote NDIS Compatible Device
I chose the second one and it solved the problem, but if it doesn't work you could try the other one. In my case, the driver that was being used was neither of these, but a special driver from Android SDK ADT bundle.
Pick one and click Next. If a dialog comes up, confirm by clicking Yes.
Wait a few seconds for the connection to restart. If it doesn't work, try disabling and reenabling USB tethering on the phone, or reconnect the USB cable.
I should also note that I'm using a custom Android ROM on HTC Wildfire S (unofficial Cyanogenmod). If you have a stock ROM with HTC Sense, maybe this method may not work and you'll need a proprietary HTC driver.

Losing ethernet port after turning on internet sharing

Just received a new iMac with Mountain Lion. I am connected to the internet through ethernet. I was setting up to share my internet access through the system prefs panel and internet sharing checkbox. This used to be called web sharing. However, once I check internet sharing to turn it on, I lose my internet connectivity through my ethernet port. If I turn on my wifi, and set the status order to use wifi works, then the internet access works ok. If I uncheck internet sharing, the ethernet port does not come back working. I have to delete that ethernet port under the Network panel and then create a new ethernet port. Then everything will work again. I have not seen this problem before.
Any ideas appreciated.

Next time the ethernet drops off, try opening System Preferences/Network, click on the Assist me button, and run Diagnostics to see if that will show you anything helpful. If the ethernet is working now, likely the test will not show anything.
If you monitor the "More Like This" box (top right), other threads appear. Opening them usually displays other threads. Maybe you can find other ideas there.

Can I convert a PB 1400's PC card port to a ethernet port for file sharing?

My plan here is to connect a PowerBook 1400cs/133 running OS 8.6 to an iBook G4 running OS 10.4 by means of an ethernet crossover cable, and move my important files (ClarisWorks 4.0 docs and games mostly) to the new computer. But the PB 1400 has no ethernet port! Is there something I can put in the PC card slot that will convert it to an ethernet port?

jpl, Denis, here's my setup:
The PB 1400 is connected to the iBook via a Farallon EtherWave/EtherMac Ethernet PC Card (with a blue arrow, PCMCIA 2.1, PC Card Standard). I have the Farallon software installed and the Farallon extension turned on. A "Farallon EN Card" icon appears on my desktop, and the little light on the cord where it connects to the card is green. I used to use the card to connect to the internet back in the day when the 1400 was my primary computer, so I'm confident it works.
The PB 1400 (name: Ben's PowerBook 1400): AppleTalk, configured to connect via alternate ethernet. File sharing, on. TCP/IP, connected via AppleTalk (Mac IP). I've tried configuring that both "Using Mac IP server" and manually by entering in the iBook's IP address and router address (the 1400 is not connected to the internet). As far as I can tell, Users/Groups is configured; it has "Ben" as "user" and "Guest" as "guest user."
The iBook (name: Ben's iBook G4) is set up basically identical to the way jpl describes his iMac above. Like his, the services panel of sharing on the iBook says "Other Macintosh users can access your computer at afp://x.x.x.6." I also manually entered the iBook's IP address, subnet mask, and router. Under my shared location, under Built-in Ethernet, TCP/IP is configured and AppleTalk is active.
Still, file sharing is not working. When I try to access the iBook from the 1400, I go to the Chooser, click the AppleShare icon, and "Ben's iBook G4" in the file server window. When I select it and click OK, I go to a screen to enter my name (Ben) and password as a registered user. I'm not sure if the password it wants is the file sharing password I set up for the 1400 or the administrator password for the iBook, so I tried them both. I also tried connecting as a "guest." In all cases, after I hit the "Connect" button, I got the error message "The connection to this server has been unexpectedly broken."
No luck going the opposite direction either. When I go to Go: Connect to Server: Browse on the iBook, "Ben's PowerBook 1400" appears in the Network area, but when I select it and hit the "connect" button, I get this error message: "The file server uses an incompatible version of the AFP protocol. You cannot connect to it."

Is there a device I can purchase to enable wifi on my old iMac, like something that plugs into the ethernet port?

Is there a device I can purchase to enable wifi on my old iMac, like something that plugs into the ethernet port?

Yes! There are lots of wifi adapters that will work with OS 9 on old iMacs. You can find a comprehensive list of them here:
http://lowendmac.com/macdan/md09/mac-os-9-wifi.html
Belkin seems to make a lot of wireless products for OS 9, so that would probably be the name to keep in mind. You can see one of these here:
http://cache-www.belkin.com/support/dl/belkin_wireless_usb_network_adapter_manua l_os9.pdf
If you're using an iMac G3, I think those are compatible with AirPort cards, so that's an option too. Good luck!

Connect WiFi to one subnet & the Ethernet port to a different subnet? (OJ Pro 8600)

Hello all,
I have an OfficeJet Pro 8600, which has both WiFi and an Ethernet port.
I have two routers at home: one for a fibre boradband line for business use and another for an ADSL line which the family use.
The fibre router has a 172.17.17.x subnet and the family router has a 172.17.18.x subnet. I would like to connect the printer wirless to the family router via WiFi and ALSO to the business router via an Ethernet cable. If I do the above;
Should I be able to print from both networks?
Is there a risk of the printer "Bridging" the two subnets in any way? (I like to keep businenss / family traffic seperate)
Any advice greatly apprecaited.
Al.
PS: I use a NetGear ProSafe Dual WAN router to sit across the fibre line & the ADSL line (it's configured to fail-over to ADSL in the even the fibre fails). Whilst the business & home networks are on seperate subnets; I do have the option to set-up static routing between them (only for the specific protocols & ports that the printer needs to work). Would this be a better idea than connecting the printer to two different networks?

Hi,

Why Are Ethernet Ports Disabled When Extending WiFi

I have an airport extreme (latest model) and have just bought a time capsule (latest model).
My extreme works as my primary WiFi and router, however I'm a fair distance from it and only get 100 meg WiFi link at best. I had hoped to connect the new Time Capsule as a wireless extender on the other side of the room where signal strength and quality are improved, and hard wire into the unit - so my backup would be quickest and the 100 meg wifi plenty for my internet browsing.
Sadly when I setup the TC to extend the WiFi it disabled the ethernet ports - is their any reason for this? it seems completely unnecerssary from my understanding of the technology and comparable products on the market, like the netgear universal extenders which have a 4 port switch to connect to the wifi on.
Can we expect a firmware update to address this or is this just plain old arrogance at it's best?

This is long standing setup that when an apple router joins the wireless of another router it will turn off ethernet ports. That includes another apple router.
But this is simply a case of wrong setup for you.
Somehow you have chosen join a wireless work.. and you should have chosen extend a wireless network. In extend wireless the ethernet ports still work..
Apple have given a reason for the lack of ethernet bridge in join wireless.. but it is fairly complex.. and seems unnecessary. The Extend wireless is proprietary method and apple was able to get around whatever the issues were.
Extend wireless on the TC.. create a wireless network on the AE.. should work ok.. I do have it running fine with Gen5 AE and Gen4 TC so previous generation.
Please give screenshots from the airport utility if you cannot figure it out.
