Problems using Macbook to connect to LAN at home

Hello, I'm a first time mac user so bear with me
My home LAN is connected by several cables in a few areas of the house, using a router. I previously had the cable hooked up to my desktop PC in a room. It works fine, plug&play most of the time. The times that it doesn't work, I re-insert the cable plug until it works. However, when I try to connect certain cables from other rooms into the macbook it doesn't work - nothing is detected, not even when I try out the network diagnostics. What could be the problem? Is it that my home network (router on all pcs except mine) is not always compatible with the router, or shoud that not be an issue?
What is the best way to make the entire network wireless, to be compatible with both PCS as well as my macbook?
Thanks for your help

The new gigabit ethernet on newer Macs doesn't autonegotiate very well. Try changing your Ethernet settings (Preferences/Network/Ethernet) by changing the duplex, speed, and/or adapter type. You just have to find a combination that works.
Wireless would be much, much nicer. Just buy a $50 router, plug it into your cable modem, setup security, and you're done.

ICHAT using macbook to connect to imac at home

Hi, I think a pretty basic question but for some reason couldnt get it to work!..Recently been away & tried to get in touch with the kiddies through ichat using my macbook (i have an imac at home)...do i have to have different a/c's or is there any other solution that i am missing?...many thanks

Hi,
I See you have linked or replied to my post.
I was trying to find out if the names were linked to your current MobileMe account.
A Trial MobileMe Account will not work in iChat if the Trial has run out. (@mac.com ones do)
At the MobileMe change from the .Mac (@mac.com name issue) you could decide to keep an @Mac.com name for your MobileMe Account.
Therefore you could have a MobileMe Account that has two working email IDs but they will not work in iChat (It is the same as if [email protected] was adding the Buddy [email protected] and trying to Video to "themselves")
I think Defcom has made it clear where you should be going for the New Account.

I have an ipad also wifi at home. Would is needed to use my wifi connection while not at home?

I have an ipad also wifi at home. Would is needed to use my wifi connection while not at home?

You can't use your wi-fi connection when not at home. Heck, my wi-fi connection bales out halfway down the back garden. Many places offer wifi hot-spots. Go google. The only (relatively) surefire way to be able to get on the internet anywhere is to have a 3G capable iPad and corresonding data plan.

My Macbook Air connects to ATV at home but not at work

My Macbook Air connects at home over a Time Machine network to my apple tv just fine (including airplay); when at work on a non-apple wifi network both computer and apple tv connect but cannot see each other. As I would like to stream video to the work ATV via airplay, this is a problem... Any ideas?

Hello Allan Robinson,
After reviewing your post, I have located an article that can help in this situation. It contains a number of troubleshooting steps and helpful advice concerning AirPlay:
iOS: Troubleshooting AirPlay and AirPlay Mirroring
http://support.apple.com/kb/TS4215
Try the following suggestions:
Ensure that other devices are not trying to stream to the same Apple TV at the same time.
Ensure that your Wi-Fi router is set up with the recommended settings for the best performance.
Certain external devices, such as microwave ovens and baby monitors, may interfere with a Wi-Fi network. Try moving or disabling these devices.
If possible, try to locate your Wi-Fi router in the same room as your iOS device and Apple TV.
If your wireless and wired networks are the same, try connecting your Apple TV to the router via Ethernet instead of Wi-Fi.
If the Wi-Fi router has an external antenna, check to see that is it connected properly and in good condition.
Use the Wi-Fi network troubleshooting guide to resolve interference and other issues.
Thank you for contributing to Apple Support Communities.

Problem using static IPs on PCs with BT Home Hub 2

Hi
Have today just been upgraded to BT Infinity using the new VDSL modem and BT Home Hub.
I have a server running Ubuntu and several PCs and laptops, mostly connected via ethernet.
Prior to the upgrade I was using the 10.x.x.x range for the network with most of the devices using static IPs. However, it seems that the 10.* range is not acceptable when configuring the IP address and Subnet mask on the Home Hub. Great! .... Not.
Anyway, so decided to switch to using the 192.168.x.x range (subnet 255.255.0.0). Have configured the router as .1.1 and my server as .3.1. However, the server is unable to ping virtually all sites on the Internet (I say all as some times www.google.com works ok.)
Also all PCs will not work with static IP configurations (using IPs like .4.1, .5.1, etc.). The only way I can get the PCs and laptops to work is to use the DHCP setting (Obtain IP from server). This is configured on the home hub as .100.1 - .100.254
I really need the PCs and laptops to work with static IPs.
Am I missing something or is this a known problem with the Home Hub? It seems that the Home Hub will only connect to the Internet if it is configured to grab an IP from DHCP on the Home Hub.
Thanks for any help in advance.
Sarah

Ok. I think I have found a work-around for this, which shows that the problem is the BT home hub.
Delete all the devices showing on the hub (in the Advnaced Settings).
Configure each PC with a static IP address with the required IP. Reboot the PC. After logging in, go to the router and enter the device showing in the home hub and set the device so that it always uses the IP address (as it will have registered the IP - even though it is outside the DHCP range). Save this. Go back to the PC and reconfigure the network settings to use DHCP and reboot the PC. The PC will then continue to re-use the original IP address, which allows this to be used as a static IP address, thus allowing it to be used for apps that need to have a fixed IP.
Repeat for each PC.
Although this works I have a feeling that the IPs used may only be retained as long as the home hub is not rebooted.
It shows that it is possible to use "static" IPs outside the 192.168.1.* range and outside the DHCP range (I was using 192.168.100.* and it worked ok). Therefore there is no reason why this should not work as static IPs, other than that the firmware on the home hub does not allow it. What rubbish.
I cannot wait until some of the other manufacturers (like Linksys, Netgear, Belkin) jump on the VDSL bandwagon and produce compatiable routers.

Connection problems using Macbook pro and 3rd gen firewire ipod

Hello,
I have been trying to get my girlfriends old 3rd gen ipod to synch on our mac but when connected, the ipod charges but is not recognised at all by the mac. nothing shows up in itunes, or the desktop but the ipod is definitely charging and connected fine. I was told by someone that the newer versions of itunes are not back compatible with these older ipods so ive wiped itunes, reinstalled the earliest mac version i can find (7.4) with no success. I cant find any mac versions older than this although windows versions are readily available.
anyone had a similar problem and know how to remedy this incredibly annoying problem?
thank you very much for your time.

is there a work around

Problem with MacBook Air connecting to Epson Stylus sx600fw wirelessly

Hi
I have been trying to set up my new Macbook Air with Epson Stylus sx600fw. Previously this printer was being used via USB with a PC. I have set up the printer on macbook via USB, but under the advice of online resources, erased that and began trying to set it up for wifi use. The printer cannot be found in the Print & Scan section of settings, and when i enter it in manually with IP address, it can find the software to install but gets stuck and says "Unable to verify the printer on your network". After further research i have tried to Ping the printer, which does not work. One thing that i notice is that the Subnet Mask is different than the apple default...for the printer it is 255.255.0.0, where for apple it is 255.255.255.0 but i dont know how to change this
Any advice for where it might be getting stuck or what I can do?
thanks!!!

Problems with Macbook wireless connection to Airport Extreme

I have been experiencing an issue with setting up and connecting my Macbook (new in April 08 and running OS X 10.5.5) and a new Airport Extreme purchased a few days ago. Essentially the Macbook struggles to connect wirelessly, or even to recognise the airport extreme. When connected directly using an Ethernet cable their are no problems (this is ultimately how I configured the airport extreme). The airport extreme wireless connection works faultlessly with my 3G iPhone and the Macbook seems to connect fine to other wireless networks. Anyone got any ideas / suggestions?

It sounds like we may have similar problems. I have a new MacBook Pro and I just bought a new AEBS 802.11n. It shows up intermittently on the MacBook available networks and I can only occasionally configure it using the airport utility, but then it fails to connect after that and I have to reset the AEBS and start over. Curiously, the AEBS shows up consistently on my iPhone, so I think this is a problem on the MacBook side. Unfortunately I can't configure the AEBS via the iPhone (at least I don't think I can).
Any suggestions would be greatly appreciated.
Thanks

Problem using JDBC to connect to WBEM ODBC driver

Hello,
I've got a problem to connect to WBEM ODBC driver using JDBC. The error is:
exception due a la requetejava.sql.SQLException: [Microsoft][WBEM ODBC Driver]Unable to connect
When I try to connect to a MS access database, replacing only the ODBC source name, it's working. I can access to the MS access db. But when I put the WMI ODBC source name, WMI, I've got this error.
Does anybody know what could happened? Is it possible to access to WMI through JDBC? With MS access, accessing WMI ODBC is working !
Thanks very much for your help.
Here is the part of the source code :
import java.sql.*;
import java.io.*;
public class Main_1 {
/** Creates a new instance of Main_1 */
public Main_1() {
* @param args the command line arguments
public static void main(String[] args) {
try {
String url = "jdbc:odbc:WMI";
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection(url);
String query = "Select * from Win32_Processor";
//String query = "Select * from test;";
ResultSet results;
Statement stmt = con.createStatement();
results = stmt.executeQuery(query);
//System.out.println (results);
catch(Exception e){
System.out.println("exception due a la requete" + e);
e.printStackTrace();
}

you have to first start the network listener before you can run the program
start TNSLSNR before running the jdbc program

Trying to use MacBook to connect Wii to internet

I just bought a Wii yesterday and I am trying to connect it to the internet so I can buy old school nintendo games. I have already spent way too much time on it and it won't work. The wii is recognizing the signal from my computer, but it will not pass the connection test. I would appreciate any help you can give me.
I am running a MacBook 10.4.11 2 Ghz Intel Core 2 Duo
I have the internet coming into my macbook through ethernet DSL and it is being broadcast through airport wireless.
Again, thank you for your help!

Ensure that the firewall on the MacBook is disabled.
Unfortunately OS X's Internet sharing has no options. If the services required by the Wii aren't passed through, you will need to buy an inexpensive wireless router and use that instead of your Mac.

HT4463 OSX Mountain Lion download fails using MacBook wireless connection

I've tried to complete this download about 8-10 times. It fails at some point, and there when I restart from Purchases, I have to start from the beginning. What's going on? I'm connected on AC power, have PowerSave options turned off so it won't go into sleep, and I've disabled all screensavers. Yet, when I come back to my download after about ~3 hours (into a 4 hour download), the Mac has been "reset" to user login screen.
Also when the app is downloading, the only progress bar I have is either in Purchases or in Launchpad: So this quote from your help document is wrong
When you find an app that you like, click Buy (you may be asked to sign in with your Apple ID). For more information about Apple ID, please see this article. When you click Buy, the app will begin downloading automatically, and the app icon will be added to your Dock with a progress bar below the app icon. Once the app is done installing, the progress bar below the app icon will go away.

Je suis sorti de l'AppStore puis ré-ouvert. Je peux reprendre le téléchargement......je croise les doigts

Problems using TimeMachine from two Macs to IOMega Home Media Drive

Hi,
This has been driving me crazy for a couple of weeks now, so I'm hoping that someone here can point me in the right direction.
I have a PPC G5 and my wife uses an iMac. I recently bought an IOMega Home Media Drive and wanted to use it with TimeMachine. I set up the G5 and got that working, but when I tried to add my wife's iMac I've had nothing but problems.
I tried resetting the IOMega back to factory defaults, deleting and then re-creating the backups folder, using usernames and passwords or a guest account, and nothing seems to work. I occasionally do something that breaks it on the G5 (running 10.5.8) but I have been able, for the most part, to get it working again, but it's never worked from my wife's iMac (running 10.6.2).
I even tried creating the sparsebundles by hand and copying them in which seemed to work on the G5 but not on the iMac. I thought that the problem might be trying to back up two systems to the same share, but I'm not sure how to split them. Is there a way to create separate backup shares on the IOMega (which seems to connect using AFP even though I've seen references to SMB in some of the forums) so that each system would use its own? Is there a general problem when trying to back up two Macs to the same network share?
The error that I tend to get is that the "backup volume is read only". On the iMac the current error I'm getting, after creating the hostname.sparsebundle image (oddly enough when TimeMachine tried creating it yesterday it dropped the MAC address...not sure why), is: "/Volumes/backups-1/hostname.sparsebundle could not be created (error 45)."
Any help would be greatly appreciated, this has been very frustrating.
Thanks,
Rob

Hi,
You don't want to hear this, but Time Machine does not back up to network drives, except Time Capsules or a shared drive on another Mac running Leopard or Snow Leopard on the same local network. It will often back-up to a USB drive connected to an Airport Extreme, but even that is, technically, unsupported, and may require running a special Terminal command to make it work.
Here's the official word: http://support.apple.com/kb/HT1733
You may find some hardware or "hacks" that might make it work, in some cases, to a degree. But use them at your own risk.
First, since this is *unsupported by Apple,* there's nowhere to go when there's trouble.
Second, you're risking a future update preventing it from working, and perhaps rendering your backups useless.
No guarantees, of course, but this might help: https://iomega-na-en.custhelp.com/cgi-bin/iomegana_en.cfg/php/enduser/std_adp.php?p_faqid=22012&p_created=1246919828&p_sid=KBbtj nNj&p_accessibility=&p_redirect=&p_lva=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PWRmbHQmcF9 ncmlkc29ydD0mcF9yb3dfY250PTEwLDEwJnBfcHJvZHM9MTAzMSwxMDQzJnBfY2F0cz0mcF9wdj0yLjE wNDMmcF9jdj0mcF9zZWFyY2hfdHlwZT1hbnN3ZXJzLnNlYXJjaF9ubCZwX3BhZ2U9MSZwX3NlYXJjaF9 0ZXh0PXRpbWUgbWFjaGluZQ**&p_li=&ptopview=1

Problems with New iPhone connecting to wireless at home

Hi everyone,
just got back from the Apple store in Bristol ( UK ) where I had my 'old' iPhone exchanged for a New one because of some problems.
Anyway I get home and I am 'trying' to get my iPhone on to my home wireless ( which is protected so have to 'add' the phone to the accept list ), the problem is when I try to add the iPhone I keep getting a 'error' message telling me that the "MAC" address ( from the phone ) is not a MAC address.
I know where to look - 'About' - 'Wi-Fi Address and there is the Mac address ( 14:8F:C6:D9:9B:6D ) , so does anyone know what I am missing or doing wrong !!
I had no problem adding my 'Old' iPhone or anything else, iPads ( one a friends for when they visit ), iTouch, Macbook ect ;-(
Not happy at the moment.

Problem with transacted JMS connection factory and transaction timeouts

          We encountered an interesting problem using transacted JMS connection factories.
          An EJB starts a container managed transaction and tries to validate a credit card
          before creating some information to a database for the user, in case of success
          an SMS is sent to the user via the transacted JMS queue. If the credit card authentications
          duration is about the same as the transactions timeout (in this case the default
          30 seconds) sometimes the database inserts is committed but the JMS insert is
          rollbacked. How can this be?
          If the authorization duration is much longer than 30 seconds everything works
          fine (both database and JMS inserts rollbacked), the same is true if a rollback
          is insured by calling EJBContext.setRollbackOnly(). The problem thus occurs only
          if the duration is approximately the same as the transaction timeout, it appears
          that the database insert is not timeouted but the JMS insert is. How can this
          be if they are both participating in the same transaction.
          The JMSConnectionFactory used is a Connection factory with XA-enabled. The result
          is the same also with the default "javax.jms.QueueConnectionFactory" and if we
          configure our own factory with user transactions enabled.
          Any help appreciated!

          It should not be.

          Make sure that your session is not "transacted". In other words,
          the first parameter to createSession() must be false. There is an
          unfortunate name re-use here. If a session is "transacted", it
          maintains an independent "inner transaction" independent of the
          outer transaction. From the above description, it seems unlikely
          that your application has this wrong, as you say that
          "setRollbackOnly" works - but please check anyway.
          Make sure that you are using a true XA capable driver and database
          (XA "emulation" may not suffice)
          Beyond the above, I do not see what can be going wrong. You
          may want to try posting to the transactions and jdbc newsgroups. Note
          that JMS is appears to be exhibiting the correct behavior, but the
          JDBC operation is not. The JDBC operation appears to have
          its timeout independent of the transaction monitor's timeout.
