Hi, i do have to set up a industrial ethernet connectíon
between a pc and a siemens s7. it's not hard to get it running, but it's getting hard to make it faster than 100millisecs per packet. the only way out seems to be a dll shipped by siemens. but all those functions need pointer like HWND - types. what to do?
cheers mario gansen it is not possible to use the siemens opc - server, because it doesn't allow update rates smaller than 100 msecs.

ethernet I/O and refreshed it sub 50mS rates . I used TCP/IP modules but
re-used the same refnum without closing the TCP/IP session. If you are not
already doing that, I hope it helps .

I have a set of 3 USB disks connected to my Time capsule (TC) via a USB hub. I usually switch the TC at night. When I restart the next day it stucks in amber state. When I disconnect the USB hub where my discs connects and restart, the TC will start properly. Any hints?
LOL.. don't switch off the TC.. this is fairly typical behaviour..
Or try a different usb hub.. but you could well and truly run out of hubs before you fix the problem.
Are you running latest firmware for your TC?
What error message is coming up in the airport utility.. amber led is a fault indicator.. look up what the actual fault is and see if it is for instance overloading the usb. You are using a powered hub??
Get one bigger USB hard disk instead of 3 smaller ones. -
We have a new iMac 2.9ghz and are running an airport extreme set up in house with several express entenders. The problem is that our son is streaming netflix and doing on line gaming and hogging all the band width. Time Warner tech suggested a hard wired ethernet connection to computer base sattion next to computer so that it can have direct conenction to internet. After much fishing of wire the connection worked great, but the wifi connection for the house is gone. I unplugged the ethernet connection and everything is fine. I read the articles about adjusting network preferences, but the issue seems to be in the extreme not in the computer. the connection goes from cable modem to extreme, from extreme to house and to hard wired conenction to other computer. Do we need a splitter before the extreme?
No. Something else is going on.
Your son may be hogging all the bandwidth but your wireless network should never simply disappear. Moreover, if your son isn't doing anything the available bandwidth for other devices should remain unaffected.
I suspect that something is miswired, and from what you describe I suspect that link is between the Extreme and the "other computer".
The way to accomplish what you propose is
Modem > Ethernet cable to Extreme's WAN port
Extreme's LAN ports > wired Ethernet devices.
There should be nothing but an Ethernet cable linking an Extreme LAN port and any other wired device. If you run out of available LAN ports on the Extreme, you need to by an "Ethernet switch" - they are not expensive, but don't call it a "splitter" or you will only confuse yourself. The switch would be connected to one of the Extreme's LAN ports, and you would connect additional devices to it. You can also use one of your Expresses for that purpose, assuming it is the current generation model with two Ethernet ports. -
Can't set up wifi or ethernet connection after clean installing XP
Hi, I recently done a clean install of XP on a friends Toshiba Equim M50-164 PSM57E laptop using instructions from this link.
http://www.easydesksoftware.com/I386.htm
I am now having extreme difficulty setting up the wifi internet connection, no wireless icon is appearing in the bottom right of screen. I tried downloading Atheros Wireless LAN Adapter 7.7.0.406.2 onto an external drive then transferring it to the Toshiba laptop but still it will not work.
It seems the drivers are not installing properly and are not showing up in Device Manager, nor can I connect to the internet using a usb cable.
Please help as my friend is extremely angry and I am now at a loss what to do.
Thanks in advance.

How to set up TC for ethernet connections to MacBook and MacMini?
Hi MacGurus
Current setup:
- ISP provided modem for incoming signal.
- TC (1st generation from 2008) connected to ISP modem via ethernet cable (TC port: the one next to USB port with roughly an O-symbol). Is this the correct port to use?
- Our ISP provider only supports 5 IP addresses and in our network we also have PCs/mobiles occupying IP addresses.
- The back-up from MacBook to TC works fine through the connected ethernet cable between MacBook and one of the three ethernet (not the above mentioned O-symbol) ports on the TC.
This is what I would like to do:
- Ethernet cables from TC to both a MacBook (from 2008) and a MacMini (from 2008), i.e not use wireless transmission
- Switch off wireless function on TC.
- Use the TC to provide IP addresses for both the MacBook and MacMini in order to leave the other IP addresses for the PCs/mobiles.
Is there any other information needed from me in order to help solving the problem?
Thank you very much in advance.
Cheers/WAThx for quick response, below some "answers".
It helps if you spell out a few things.
- ISP provided modem for incoming signal.
Who is the ISP? And what model is the modem provided? Is this dsl or cable or fibre or something else? *** ADSL
- TC (1st generation from 2008) connected to ISP modem via ethernet cable (TC port: the one next to USB port with roughly an O-symbol). Is this the correct port to use?
The answer depends.. is the ISP modem also a router? Is the TC setup to bridge or route? *** Yes, the modem is also a wirelss & ethernet router. *** I do not know if the TC is bridge or route, how can I see that?
- Our ISP provider only supports 5 IP addresses and in our network we also have PCs/mobiles occupying IP addresses.
Here is where I am getting confused actually.. Most ISP supply just 1 IP.. the router translates that single public IP to all the computer and devices on your network which run on a private IP network.
Is the ISP giving you 5 public addresses?? Are they ipv4 or ipv6? Setting up blocks of ip addresses is more a business setup.. where multiple devices need direct internet access eg servers.. without being hidden behind a NAT router.
So the more info you can give the better.
*** Sorry for confusion. It is likely that the ISP provider gives 1 IP address, and that the modem generates up to 5 IP addresses. It is most certainly only a standard private setup, no business setup.
This is what I would like to do:
- Ethernet cables from TC to both a MacBook (from 2008) and a MacMini (from 2008), i.e not use wireless transmission
- Switch off wireless function on TC.
- Use the TC to provide IP addresses for both the MacBook and MacMini in order to leave the other IP addresses for the PCs/mobiles.
What IP addresses are you getting now?
If you plug ethernet to the macbook and mini now.. and turn off wireless, what IP address are they getting??
If the TC is in router mode they should get 10.0.1.x IP and be able to ping and share with each other.. without needing to do anything.
*** I am now connected to the modem (wireless), as I cannot connect through the ethernet cable. -
I recently added a new printer to a 2005 vintage PC that is running windows 7. It used to go through a router in my wifes upstairs office to the time capsule by wired ethernet (cat5) but when I added her new local printer thought I would network it, big mistaked, lost all my ethernet connection and she cannot get to the internet. Wireless not an option. How do i set up again the ethernet connection and i will only USB the printer locally this time for the windows pc?
Tried windows diagnostics, and besides telling me to reset everything and turn router off and on etc. I am in an endless loop.
Other Mac products are not impacted by this issue.I see no direct connection.. a printer and the computer setup for internet are not related.
But it sounds like the router in the wife's office is now in the wrong mode..
If you have an existing main router replace the second router for a switch .. that is the easy way.
Otherwise you need to bridge the router if it has that option.. most do not. Or use wan bypass.. where you turn off the dhcp server in the router and fix its ip to match the range of the main router.. this is the hassle of using router as a switch.
BUT I am making a huge number of assumptions.
What I need is the full network layout.. a quick picture would help.
I need main modem.. main router.. (maybe same box or different).. make model and current IP address and how dhcp is setup.
I need secondary router.. if that is what it is, IP and settings.
I want the printer type and model. How it is connected.
BTW I much prefer to see a network printer plugged into the network rather than usb.. it is only a matter of sorting the IP settings and driver pointing to the network rather than local.
Or you should think of it as a broken washing machine and call the technician.. who could fix the whole lot in an hour. -

If that won't work, perhaps you can use Find my iPhone from a computer in your iCloud.com account to erase the device.

This has nothing to do with the Find my iPhone app being installed on the phone, but you do have to have Find my iPhone activated in the iCloud settings on the phone. -

When I try to open an .ai/pdf file received through my email, it won't open and asks for a password. I have never set up any kind of password for email security, but have tried typing in my standard passwords. Nothing works. I wonder if it has anything to do with the use of my Wacom3 Tablet...I've been having trouble with it and was getting the same message when trying to open the User's Manual in my Applications/WacomTablet file on my hard drive. Any suggestions? I just downloaded the latest version for the Wacom and recently upgraded to Snow Leopard 10.6.7 (which I hate, and my CS3 hates, etc.)
It sounds like you have a a password-protected PDF. The password was set by the person who encoded it.

My printer keeps going off line with my network. have to set everything up every few minutes.
After getting my HP photosmart 5510 all in one printer setup on my wireless network and setup for eprint, 2 problems occurred. The printer keeps jumping off of the network, and I have to set everything back up again. Also, even with eprint still completely set up, none of the emails that I send are printing out???
Please HelpFor those who are experiencing ongoing issues with their web services, you can attempt to try the following steps that may help resolve your problems.
1.) Completely shut down your printer and restart it
2.) If you have prints that have not printed, log into ePrint Center (or create an account if you do not have one) and then look for your printer status. If printer status is green but you still have pending jobs, delete the pending jobs one at a time (Starting with the oldest first). There may be a print job stuck in the queue that further restricts other jobs from completing.
If option 1 or 2 above still doesn’t work, removing web services and re-adding web services will cause the printer to reattach to the cloud.
Please note that if you attempt option 3, you will get a new eprint email address (and lose your custom one with no ability to get it back) furthermore, you will need to re-add your printer back to your ePC account.

I have Firefox set to automatically look for updates then ask if I want to install them. I do this when convenient (may also need to restrict downloads on another machine when paying for Internet use by amount downloaded) Until recently it did just this. Firtefox 6 seems to have downloaded & installed (& lost all passwords & cookies) I assumed this happened when someone else was using the machine & said yes. It has now automatically downloaded the latest update automatically and the settings are still set to ask me first. What has happened & how can I stop it please?
