Ethernet Conundrum

I have just bought the Netgear WNDR3700 dual-band.
Before I put my office through it via a gigaswitch I thought I should test it out.
All the correct lights on - modem and router handshake all working.
Plugged ethernet from router to MBP. No connection, though DHCP issued IP and ethernet showing green light.
Loaded Parallels Window 7 from my MBP to experiment. Lo and behold I have internet access. How odd!!
Unplugged ethernet cable and set up 2.4 & 5 Ghz dual band. Both work very well in MacOS.
Why does ethernet not work on MBP but does on MBP loaded Windows 7?
Thanks
Andy

Have you checked the 'DNS Server' field of your ethernet connection? Click on 'advanced', there you can add more DNS servers (or remove servers).
What have you tried? Did you just open a browser to see if you had an internet connection or did you actually use some networking utilities to see if the local network was working?
Can you access the webinterface of your router on your Mac? Or ping it? There obviously is a connection if you get an IP address...

Ethernet printer conundrum

Ethernet printer conundrum.
===========================
My "network" is minimal and simple:
The DSL connection comes from the street to a Siemens/SpeedStream DSL "modem"/hub supplied by the phone company (my ISP). My desktop Mac is connected by Ethernet wire to one of the five ports on said "modem"/hub.
A Netgear RangeMax Next wireless router Gigabit Edition is also connected to one of the five ports of said modem/hub.
So far so good.
I can connect to the Internet through the wire and my wife's Macbook connects to the Internet wirelessly through the Netgear.
Then, I connect a Samsung ML-2850ND monochrome laser printer that replaces my recently, finally deceased LaserWriter IIg, to another port on the DSL modem/hub. Great, I can print from my desktop machine.
But the wirelessly connected Macbook cannot print.
Then I unplug the Samsung printer from the DSL modem/hub and connect it directly to the Netgear router. Now the Macbook can print, but it cannot connect to the Internet.
Will a network SWITCH to split the printer connection between the two routers help? Or am I dreaming?
Any other suggestions will be greatly appreciated.

I think you should arrange a completely different configuration than the currently used in your setup.
I'll tell you how I'd conect it if it were my home network (and I have set several DSL modem and wireless routers this way).
First, connect the desktop computer to a LAN port on the Netgear router using an Ethernet cable, enter the configuration page and run the Setup Wizard, as described in this Netgear k.b. article.
You will need to enter the username and password provided by your ISP. You can get them thru the DSL modem configuration page, or by calling your ISP Support desk.
Basically, when you set PPPoE on your wireless router, it is the router the one that obtains the external ip address from your ISP, instead of the modem, which is put into "Bridged mode".
Then, the router will assign an internal ip address to every device you connect to it. Also, check the router has a lease time set to "forever".
If the Netgear router Setup Wizard fails to set to PPPoE mode, then you'll need to manually enter the modem into bridging or "bridge mode" and configure the Netgear router manually to PPPoE.
The reason I suggest you to implement this setup is that, not only the network printer and the computers will get to work they way they do, but also, in the future, if you want to add any other device to your network, you'll only need to plug it into a LAN port on the Netgear router, or join the wireless signal provided by it. It's a robust configuration.
The tricky part may be to get the modem into bridge mode...

WiFi to Ethernet Internet Connection Conundrum - Can you help?

I'm trying to figure out whether it's possible to use my G5's ethernet port as a hub to connect my 12" G4 to my Wifi network. The G5 is connected via Wifi as it's two floors away from the modem.
My G4's airport seems to have gone screwy, and in the meantime, until I fix it, I need to get internet connected without directly plugging in to the far away modem.
The Wifi network is not an "airport" network (the wireless modem is a Thomson Speed Touch 585 model). If it was, I'd use my Airport Express' ethernet port. I can't get internet via WDS for some reason.
Any solutions?

With the Laptop set to DHCP and Ethernet dragged to the top of Network>Show:>Network Port Configurations, try Finder>Go menu> Connect to Server, then either browse or type in the IP of the G5.
Oh, almost forgot, if the G5's Airport has an IP with 2 in the third spot, like x.x.2.x, then it won't work.
We could try it Manually, though Apple says you can't, it sometimes works, then sometimes doesn't but works right after you try Manually then go back to DHCP!
If you give me the G5's Airport IP, I'll tell you what to try on the book.

We have a wireless internet conundrum (who doesn't).

We have a wireless internet conundrum (who doesn't).
I have a new Airport Extreme Base-station (n-standard) in our basement. I bought this after frustrations with linksys and belkin routers as far as distance from router connection is concerned. My issue is not speed. Specifically, I have the router in the finished basement with my "precious" iMac Intel which is ethernet hardwired to the base-station. The PROBLEM is getting a wireless connection with my daughter's iMac G4 on the 2nd floor.
This makes the problem interesting (from system profiler):
iMac Power PC G4 (3.3)
CPU 1 GHz\Mem 768 MB
iBook G4 Power PC (1.5)
CPU 1.42 GHz\Mem 1.5 GB
Both of the above computers have the following wireless specs:
Airport Extreme Card
Firmware 405.1(3.90.34.0.p18)
Channel 1
The iBook shown above picks up the connection perfectly well in my daughter's room with a full signal level indicator but the iMac does not connect- the signal indicator is almost zero. The iMac when moved to the first floor is fine.
The way I see it one solution might be to move the router to the first floor and take my "precious" off of hardwire connection and go wireless and experience a speed drop.
If I have no other choice, I would prefer to throw a "few bucks" at the problem and keep my "precious" blazing. Does anyone have any other ideas? Can I buy something to extend the Airport signal further? An antenna for the Power PC iMac? Could the iMac's Airport Extreme Card be bad? Is there such a thing as an wireless n-card that plugs into a UBS port?
Thanks for any suggestions.
iMac Intel 2MB Ram Mac OS X (10.4.10)

The iBook shown above picks up the connection perfectly well in my daughter's room with a full signal level indicator but the iMac does not connect- the signal indicator is almost zero. The iMac when moved to the first floor is fine.
It is very possible that you may have some form of Wi-Fi interference in the basement area that is preventing you from getting a good clean signal when the iMac is located there.
I suggest you perform a simple site survey, using utilities like KisMAC, MacStumbler, iStumbler, or IPNetMonitorX to determine potential areas of interference...and then, try to either eliminate or significantly reduce them.
Can I buy something to extend the Airport signal further? An antenna for the Power PC iMac?
Check out QuickerTek transceivers.
Could the iMac's Airport Extreme Card be bad?
Since you mentioned that you got good performance on the 1st floor with the iMac, I would doubt there is something wrong with the AirPort Extreme Card in your iMac.
Is there such a thing as an wireless n-card that plugs into a UBS port?
Same outfit, QuickerTek now offers 802.11n upgrades for Macs. However, the model for the iMac is internal and does not plug into a USB port.

Ethernet connection to Apple TV3 used to make possible, now prevents Airparrot mirroring

Because WiFi in my vacation rental is provided by multiple servers, I can't get a reliable connection between my MacBook Pro and my ATV3 brought from home except by using an ethernet cable connection. Those of us still using Snow Leopard have the additonal issue that we need Airparrot or something like it to control mirroring. The ethernet-Airparrot solution worked fine for several months, but suddenly -- possibly due to an ATV3 upgrade -- it doesn't. If I want to mirror, I must use Airparrot. But the ethernet shuts down the Airplay that makes mirroring possible. However, only if I use ethernet can Airparrot find the ATV3. Your thoughts on solving this conundrum are welcome. Otherwise, something gets chucked.

Solved my own problem.
Having recabled my MBP with the Apple TV using an Ethernet cable, I went into System Preferences/Sharing and enabled Internet Sharing. From the drop-down menu, I chose Airport (thought it could be any modality in System Preferences/Network) and checked the box for Ethernet. Went back to Airparrot and System Preferences/Sound to make sure Apple TV was picked as target and audio was enabled. Now it mirrors my desktop and audio, via Ethernent cable. All I have to do to switch back to WiFi Apple TV. Works like a charm.
Whenever you need a direct link for mirroring, this way is easy and reliable.

How do I add an airport extreme to a cable modem with only one ethernet port, while keeping that port connected to my Mac?

I have a mac pro connected by ethernet to a cable modem via ethernet. There is only one ethernet port on the modem.
I want to keep the Mac connected via ethernet for speed. Is there a way that I can add an airport extreme to this set up - for my ipad and roku, and for guests to use - or do I need to buy a router to put between the modem and the mac?
If I need a router, what kind?
Thanks.

The modem connects to the WAN "O" port on an AirPort Extreme router.
The Mac Pro connects to one of the three LAN <-> ports on the AirPort Extreme router.
Or if you do not need the ability to connect a hard drive to the USB port on the router, you can save a bit by using an AirPort Express.
The modem connects to the WAN "O" port, the Mac Pro connects to the LAN <-> port
Either the AirPort Extreme router or AirPort Express router will allow up to 50 wireless device to connect.
There are many other wireless modems offered by other manufacturers as well.

GPIB Ethernet/100 Performance

Does anyone have some real world peformance measurements on the transfer speeds of the NI GPIB-Ethernet/100 box. I am very disappointed in the performance of a block read which is approximately 6ms/byte transfer (tested from 20 bytes to 32kbytes block transfers). This is on a 100 Mb Ethernet. I can ping the box with 64 byte round trip transfers at ~0.7ms/packet.
I almost feel that the GPIB-Ethernet Box is not buffering my GPIB transfers.
Thanks

Actually ignore my question. My transfer speeds are ~6 microseconds/byte (not milliseconds!). This is still a little slower than I would like, but not totally unreasonable! Note the vertical axis in the included plot (pdf) is in ms, so the linear coefficient in the fit equation is 13 microseconds/(16 bit word).

I have a TC which is connected wirelessly to my router. I would like to connect a mac in another location via ethernet to the TC. I can't seem to get it to connect. Am I missing something?

I have a virgin Superhub which serves my wireless needs throughout the house. I have a Timecapsule which connects wirelessly to the router with no issues. I can backup my MBP over wireless easily. I have now got another machine in a different part of the house that I would like to connect to the network. It doesn't have wireless so ethernet is the only option. I have a number of options 1) run cabling - not really possible 2) buy a powerline network system or 3) use the timecapsule to connect to the network/internet.
I like option 3 because
(a) - I don't have to spend any more money and
(b) - my wife wont complain about cables also see (a)
Should using mixed wifi and ethernet clients on a timecapsule work? if so is it a feature I can use out of the box so to speak?
Thanks

No a TC cannot do what you want.. it is now in dumb stupid wireless join mode.. and it turns off the ethernet ports.. in case you want to use the TC as a wireless bridge to multiple clients which is plainly wrong.. (only airport express is allowed to do this since it has only one ethernet port).
Welcome to Apple. (The plainly wrong above is a figment of Apple imagination.. of strict network protocols.. but unhelpful for a home device. maybe also to encourage sales of expresses.)

Blue screen error when connecting an ethernet cable

I have a Compaq Presario 5300US desktop that I'm trying to upgrade. It has 512mb (max) of memory and a newer video card than the factory one. I installed Vista Home Basic on it with no problems. I also installed a pci ethernet card along with the Vista drivers that came with it. I checked tha card's properties in "device manager" and it said "This device is working properly". I haven't plugged in an ethernet cable to the card at this point. Everything is working OK, but as soon as I try to connect the card to my router, I get a blue screen with this message:
Hardware Malfunction
NMI: Parity Check / Memory Parity Error
*** The system has halted***
I don't get any memory errors as long as I don't try to use the ethernet card.

Hello @larrycarol99,
I understand that after upgrading your computer when you plug in an ethernet cord you get a hardware malfunction error. I am providing you with a Microsoft Support document: Hardware Malfunction Results in System Error Message that explains what causes that error and provides steps on fixing it. I am also including a link to the Compaq Presario 5300US Desktop PC Drivers page, which unfortunately does not have any drivers for your computer running Windows Vista.
I hope this helps. Thank you for posting on the HP Forums. Have a great day!

Ethernet to USB adaptor no longer being recognized by my mbp

I have an older macbook pro, which is running mac os x 10.5.8. The ethernet port is broken so I have been using a mac Ethernet to USB cable because there is no wifi at my college. I got the cable to work for a while, then I unplugged it and my computer no longer recognizes it. When I used to unplug it and plug it in I would get a message by the airport symbol that said something along the lines of ( new network usb-ethernet availible, which then would allow me to go into network preferences and give me the option to connect to the usb ethernet). Now when I go to setting with the usb ethernet device plugged in I no longer get the option to use usb-ethernet adaptor, and cannot connect to the internet.
Both the cable and port have been tested and they both work. I also havn't installled any new software recently so I have no idea what I have done wrong.
Thanks for your help

Hi Dibenkorn,
Yes, both USB ports are not recognizing this lacie external hard drive. I also tried the SMC reset but that did not change anything. I have another external hard drive (smaller one) and it works on this computer fine and like I said before the Lacie works fine on my other (older) MacBook. I just can not figure out what went wrong or what happened...

HP Color LaserJet MFP M476dn - Impossibly slow ethernet

Win7 - 64 bit on typical small office network setup (Comcast internet, Linksys Router, half computers on wifi, half wired).
Upgraded from terrible old Brother multi-function printer.
We print some files from remote desktop (using redirected printers.. as in, the remote desktop session has the ability to print through our computers to our local printer).
Sometimes the files are large (10-20mb).. and the Brother printer sends it right over in about 1 second.
New HP Color LaserJet MFP M476dn goes as slow as you can imagine.. I can sit a watch the printing dialog box and watch it 256kb........512kb........768kb.......... out of 15mb.
I have tried a bunch of combinations of different drivers (PCL5 etc), link speeds on the printer, RAW processor, Port types, and so on, but can't find the right combination..
I should mention that we are using the exact same ethernet cord as the old Brother printer. Also, the HP is set to a Static IP.
Please help!
Thanks,
Eric

I had this exact problem. I've had the printer for about a month and it was very fast at first. I really like the printer, especially the duplex ability. Over the past week or so it became excruciatingly slow. I just finished downloading the new firmware and drivers but before installing them something made me check the Ethernet cable which is plugged into my Airport Extreme 802.11n Gigabit router. It was loose and partially pulled out so I plugged it back in all the way and the printer went back to printing the way it is supposed to.
You might want to give this a try. Perhaps try another Ethernet cable or direct connection via USB if that doesn't work.

How to print on HP LaserJet 2200 over Ethernet?

Hi,
I did an upgrade to Snow Leopard and would like to print on a HP LaserJet 2200 over Ethernet. OS X and the HP printer drivers are up to date now.
The printer has been cold reset and on the configuration print out there's the IP address 0.0.0.0
Now my question is how to get this printer to work with Snow Leopard over Ethernet? I did not find a tutorial how to assign an IP address to the printer first so I got stuck.
Could you give me a hint where I should start with the configuration first?

OK, now the printer works
I reset the router and checked if DHPC is running.
I reset the printer (hold down the GO button, turn the printer on and continue to hold the GO button for five to ten seconds).
Checked at router that the printer is visible as network device.
At the router I assigned a fixed IP address to the printer.
At OS X System Preferences > Printer I added a new printer with "HP Jetdirect - Socket", the fixed IP address and the correct printer driver "HP LaserJet 2200".
Now the printer has been recognized well by the system (Tray 3, Duplex and printer RAM) and printing works.
THANKS.

Printing to AppleTalk printer via Ethernet

I’ve read all the pages I could find about this topic, and several threads on this forum, and tried everything suggested but I still can’t get my Mac Mini with OS X 10.7.4 to print to my HP printer.
My hardware setup is thus: HP LaserJet 6MP is connected by its AppleTalk cable through an AsanteTalk bridge to an Ethernet hub. (There is also a DSL box connected to the same hub). The hub is connected to my Mac Mini via the Ethernet port. This setup worked fine with my old eMac with 10.3.9. The printer was recognized automatically and I did not need to do any special setup, at least with 10.3.9. I understand that Apple dropped support for AppleTalk with Snow Leopard, but is there any possible way to make this work?
I bought a Mac Mini with OSX 10.7.4, and I have connected the same hub to the Mac Mini via the Ethernet port. The DSL works fine. But I am unable to print. I have read through the following pages and tried everything suggested on these pages:
http://support.apple.com/kb/HT4670
http://support.apple.com/kb/HT4507
http://gigaom.com/apple/how-to-resurrect-your-appletalk-printer-in-snow-leopard/
What I have done to set up the printer is:
1) I have downloaded the latest HP drivers and run Software Update today, to verify that all my software is current.
2) I powered down everything and then powered everything back up starting with the printer, then the hub, then the Mac.
3) In System Preferences -> Network, I noted that it says “Ethernet is currently active and has the IP address 76.212.150.40” So I am assuming the IP address of the printer is 76.212.150.40 However I'm not sure if I'm correct in assuming that.
4) I ran Terminal and typed PING 76.212.150.40 and got a series of replies,
64 bytes from 76.212.150.40: icmp_seq=0 ttl=64 time=0.071 ms and so forth.
5)I go to System Preferences -> Print & Scan. I click the + to add a printer, then the IP icon. For Protocol I have tried all 3 options, but the last time I chose Line Pinter Daemon - LPD for the protocol, because it’s an old printer.
6) For the address I put in 76.212.150.40
7) The “Print using” field came up automatically with Generic PostScript Printer, but I chose Select Printer Software... and chose HP LaserJet 6P/6MP - Postscript.
8) I click “Add” and I get a warning message, “Unable to verify the printer on your network. It cannot be currently determined if ‘76.212.150.40” supports the Line Printer Daemon Protocol. Would you still like to create the queue?” I click Continue.
9) The next dialog box asks me to verify my printer’s options (the only one is Total Memory and I set that to “6 Mb or more” because the printer has 7 Mb of memory. I click OK.
10) The printer shows up in the list of printers. Under it says, “Idle, Last Used.” I print a test page of one sentence, using Tex-Edit Plus. The printer’s status changes to “In use” in printer list. In the Print Queue, it says that it is printing my document, but under that it says “The printer is busy.” And it stays like that.
I have tried deleting that printer, and adding it again with all the above steps. I have also powered down the whole system and started up again. Now it says, “The printer is not responding.” and if I turn the printer and hub off and then back on again, I am back to “The printer is busy” message.
Is the problem here that I am trying to still use AppleTalk or LocalTalk? Besides the LocalTalk port, the printer also has 2 parallel ports (a B-type and a C-type) and an infrared port that I have never used. Would a parallel-to-USB cable or adapter solve this?
Is the problem that the DSL is interfering with the communication between the Mac and the printer? Is the problem with OSX 10.7.4? Or did I make a mistake in the setup process?
Is there a solution for this or will I have to buy a new printer? The printer still works fine and worked well with 10.3.9. I would hate to just discard the HP LaserJet because it is a workhorse that has printed over 120,000 pages for me and still seems perfectly useable.
Thanks for any help or suggestions.

You suggested earlier that "The only way you can print to an AppleTalk printer from OS X 10.6 or later is if the printer is a shared printer running on a Mac running OS X 10.5 or earlier.
I am using a Macbook Pro with 10.7.4 and like Bob Weaver, I have tried all of his methods as well. What is the set up as you describe above. I have an old HP laserjet 5m with the Directjet.
To be absolute about things, I should change that wording to indicate AppleTalk only printers need to be shared from a Mac running OS X 10.5 or earlier.
You have a JetDirect card that allows for other connections/protocols other than AppleTalk.
I am trying to use it with my mac using an ethernet cable. I cannot ping it, I cannot see it but my ethernet shows its connected with the green light. The HP is a work horse and I would hate to turn it into a door stop. Iv'e printed the config sheet and have entered the IP address with no luck.
I cuurently use a Netgear Wireless Router/Modem and have tried using its ethernet ports as well but I continue to have no luck. Can I print to this thing or is it a paperweight
You appear to be on the right track here, but you appear to need to make some changes to the JetDirect setting to use it on your network. I have never worked with a JetDirect card, so I cannot give you all the specifics. Bob Weaver's post will probably be of more help than my outline. You may also want to search the Apple Discussion boards a bit more -- especially the OS X 10.6 archives. There were a lot of posts regarding switching over from AppleTalk to network cards.
The basics are:
1. Set the JetDirect card to use a routable address that your router can use. You can look at the router's configuration to get the expected range of addresses and the gateway address for the router. You will also need to pay attention to the subnet mask to make sure the two devices are on the same network.
2. I generally recommend that you reserve an IP address on the router for the printer. You will need the JetDirect's MAC address to do this. The benefits of setting a static IP address for the printer is that you can power down the printer assuming it will hold the set address. This saves a lot of time and headaches.
3. When you configure the printer with the static IP address, subnet mask, and router gateway, be sure to turn off the option for it to get its address using DHCP. That is, you don't want the printer to get a new address from the router every time you power it up or down.

Powerbook G4 can't connect via ethernet but connects via airport

We have a small office network connected to an Efficient Networks DSL router that's managed by our isp. The router has 4 ports and a linksys 8 port switch is connected to one of those ports. Another D-Link wireless router/switch is connected to another port.
2 i-macs connect without problem via ethernet cable. They are set to DHCP and get 192.xx private addresses. Both run 10.4.5. Another older imac running 9.2.2. also has no problems.
I recently purchased a powerbook G4 and it will not connect via ethernet to the Efficient networks router. At first it was connected to the linksys, so decided to connect it direct to the Efficient Networks router. With DHCP, it acquires a 169. internet address which is self generated (i.e. no real connection). I tried to give it a static private address (talking to the isp provider). They could see the powerbook but saw all zero's (presumable mac address). By the way the Powerbook works perfectly at home connected via ethernet cable to a D-Link router connected to a cable modem so it's not a physical problem. I even checked the ethernet cable I used in the office with another computer - no problem.
When I switch to airport in the office, the powerbook connects to the network and the internet. I get some strange warning messages showing the server's and the router's private ip addresses. I click ok, and the powerbook finds an unassigned private ip address. It's the only way it will work, but it causes problems, because I can't connect to one of the network printers. Speed also isn't great.
Can anyone give me advise how to proceed. I am no expert on this stuff so keep it as simple as possible.
Tks

Tim,
Thanks for your help. Here's what I've done before reading your e-mail. The D-Link DI-524 wireless router is connected to the Effiicent Neworks DSL router as you mentioned. One ethernet port of the EFF.Net. router is connected to the WAN port of the DI-514.
Because I have a D-Link router at home which works flawlessly with my powerbook, I decided to connect the ethernet cable of the powerbook to the D-Link which has 4 ethernet ports. Lo and behold, the powerbook acquired a private ip address and connected to the LAN and internet!
When I connected the powerbook direct to the Efficient Networks router, it could not communicate. I believe that there must be some software incompatibility between the powerbook and the Efficient Networks router. By connecting to the D-Link, the D-Link assigned an ip address to the powerbook, and it could connect to the server, lan, etc..
Only problem is that I have a Brother network printer that cannot connect to the powerbook. My powerbook cannot find it on the network. Because there is a linksys switch connected to the efficient networks router's third ethernet port, maybe as you said, going through the D-Link via DHCP (when the Linksys is also acting as a DHCP server, might cause this type of problem. What do you think?
As a final note, other imac G5's connected to the linksys switch (which then connects to the Efficient Network's router) have no problem connecting to the lan or internet and have no problem connecting to any of the printers. When I put the powerbook on that switch, I could not connect to the internet - i.e. whether connecting via the lynksys switch or direct with the efficient networks router - same results: no internet connection whether manually or via DHCP.
So the imac G5 has no problem with the efficient networks router but the powerbook G4 hits a brick wall. The G4 likes the D-Link router. I am concerned (and I will have to check this) that if I turn off the dhcp server feature from the D-Link, that whatever software issue crops up between the powerbook and the Efficient Networks router, will rise up again, because the D-Link will act like a simple switch (just like my linksys switch), and we'll be back to square zero. In any case, no harm in trying. This may be the cause of the Powerbook not seeing that Brother printer (even though it sees another printer and other macs).
Having spent hours reading about network problems, I think it's safe to say that macs have problems with certain routers. Why a G5 works and a powerbook G4 doesn't is beyond me, but clearly software must play a role.

In my small office ethernet network all of a sudden one of my imacs cannot be connected to. It can connect to all other computers and can access internet, but as soon as someone tries to connect to that mac, it disconnects from the network. Any ideas

I have a network of 9 macs that connect via ethernet and a router. All of a sudden one of the macs cannot be connected to. It can connect to all others and the internet, but no one can connect to that one. I have appletalk active and file sharing on, but everytime someone tries to connect to it, it is not on the network. Additionally, the personal file sharing keeps turning off even though I have it locked. Any ideas?

Hi orangekay
not sure where you got the idea that I have
bizarre encrypted filesystem plugins and scripts you have manipulating them all the time
because I do not have any such running, just normal Applescripts that do tasks that could be done by hand.
