Weird Mac:Router problems

Hi all,
I'm having a really annoying problem between my Mac (G5, dual 2.5Ghz PPC running 10.4.11) and a wireless router.
I don't think the problem is with the router or with the router's web access because:
a) My iPhone connects to the router with no difficulties at all and loads web pages at an appropriate speed;
b) My Powerbook (G4 PPC, 10.4.11) connects to the router with no difficulties at all, and loads pages at an appropriate speed when connected both wirelessly and via ethernet;
c) My wife's Macbook (10.5.7) connects with no difficulties at all
d) All the devices that connect ok do so from various locations, often the same location as the G5 or from further away than the G5. I really don't think it's a location problem
e) This is a 'new' problem: the G5 has been connecting successfully to this network for a few years with no problems at all. Nothing has changed that I'm aware of. I was away for a few weeks (machine was switched off) and it worked ok at when I got back but now doesn't.
But the G5 drops the signal, fails to connect (error message = "there was a problem connecting to [name of network], do you want to try again?") and even when connected (ie when the Airport icon shows full signal strength) is either unable to load pages or extremely slow. For example, 15+ minutes to load the router's interface, or similar for a website.
The problem is the same for both Safari and Firefox.
Why? I've fiddled with the Airport arial on the back, I've logged out and in again, restarted the machine etc but am at a loss to think of what to try next.
Can anyone advise what I should try next, please?
Thanks!

Nothing - absolutely nothing at all. This morning, the first time I opened Safari, it immediately responded with one of the standard messages ('Safari can't open the page...'). I quit and reopened it. This time it loaded my home page after a few minutes, but then failed to open this page (Apple Discussions) saying the server unexpectedly dropped the connection. (I've logged on to this site using my Powerbook and Safari from the same desk as my G5).
The only Console entries from today (for the G5) are saying that Dashboard Client needs an update, the weather widget failed to fetch data (unsurprisingly) and the following message (from its time stamp it looks like it occured on start-up):
Sep 14 09:42:58 jasons-power-mac-g5 mDNSResponder: mDNSPlatformSendUDP sendto failed to send packet on InterfaceID 0181B200 en0/6 to FF02:0000:0000:0000:0000:0000:0000:00FB:5353 skt 9 error -1 errno 49 (Can't assign requested address) 2706483934
Does it mean anything?
Thanks for your help!

Weird wifi/router problem?

When I first bought my Ipod touch, I could not access the Internet because it would never connect to my router. The Ipod recognized the router in the "choose a network" section of the wifi settings, but when I tapped my router's name, it said it was unable to connect. I thought it was because the "wireless" LED was not lit on my router. One night, I tapped my router's name and it somehow worked. It worked for about a month and the "wireless" LED was lit on my router. But then it stopped working and the wireless LED is off again. I didn't change anything, I don't know what happened. Can anybody help me out? I have a belkin N wireless router and I've tried restarting it. I've also tried resetting netowork settings on my ipod.

Focus your energies on your router as it apparently is only broadcasting the wireless signal intermittently. Try a router reboot - unplug the A/C power, wait 30 seconds, plug it back in and let it re-initialize. You might also want to look for a firmware update and install that as well. However, if this keeps happening, it is time to go router shopping.

Router Problem - Works with Windoze, Linux, but not with Mac

I can't seem to get any router to work with my Mac.
I've tried a Linksys 'b' router, a Netgear 'g' router and a Belkin 'g' router.
No joy.
When I connect my Mac directly to my cable modem (Motorola Surfboard), there are no issues. When I connect the router in between, the Mac pulls the proper ip address and I can ping the router, but I can't get any further. If I try to ping an outside ip address (such as the 4.2.2.2 dns) I get the error message "ping: sendto: Cannot allocate memory". [Does anyone know what this message means?]
A second computer (IBM NetVista) connects reliably using Windoze XP. The same machine, booted in CentOS also connects reliably (after disabling the firewall).
Note, these are all wired connections. I'm not even trying to use wireless yet. The cables all check out, since they all work in other configurations (the Mac->router cable is the same one I use for Mac->Surfboard, and the router->surfboard cable works when connecting from the NewVista machine.
I thought the Mac problems might be firewall related. I had "Brickhouse" installed,but it has since been removed. My network settings no long advise that there is any firewall software in place (previously Sharing > Firewall was greyed out with message that other firewall software was installed). Sharing > Firewall now reports "Firewall Off".
I know the routers work, since I can connect from the NetVista machine. I know the cables are good, because they all work in other configurations. I know the Mac is seeing the router, and the router is seeing the Mac because a correct ip address is pulled. I can even communicate between the machines (ftp,ssh) but I can't get internet access using the Mac through the router.
Oh yeah... one other oddity. When I have personal web sharing enabled, an attempt to access the router setup page at 192.168.1.1 fetches the local server index.html page instead of accessing the router. When web sharing is off, I get a "you are not connected to the internet" message.
Any insight?

Very strange indeed!
Only 2 suggestions at this point...
Get Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, reboot holding down CMD+s, then when the prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 5 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Try dragging these files to the Desktop & Reboot...
/Users/nnnn/Library/Preferences/com.apple.internetconnect.plist
/Library/Preferences/SystemConfiguration/preferences.plist
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
/Library/Preferences/com.apple.sharing.firewall.plist

Peculiar Mac Pro problem just cropped up

I've got a Mac Pro, about 5 months old. It has 4 hard drives and 8 GB of RAM. It has been running flawlessly for 5 months and it SEEMS to still be running flawlessly except ....
Today I've been unable to download anything from the net. It started this morning and was limited to one particular piece of software, but now the problem arises whenever I try to download something from any site.
What the problem ISN'T:
a. a Comcast problem (I have both a MBP and an MB wirelessly connected to the same network and I don't experience the problems on those machines.
b. a router problem (see "a"), but in any case, I've reset the router, reprogrammed it. I've also reset the cable modem. Everybody else gets to download. My Mac Pro won't.
c. a network problem. Everybody can navigate all over the net. The problem ONLY arises when I click on a link to download something. Neither Safari nor Firefox works; they both just sit idly going "duh, what do you want me to do?".
d. a browser problem (see "c" above). I've cleared the caches and it changes nothing.
What it SEEMS like:
a firewall setting that has somehow changed, although I've changed nothing.
What happened between yesterday and today:
Mostly absolutely nothing. I did receive my fourth 500 GB drive and plugged it in and formatted it. No software that I can recall downloading between last night and tonight.
I've repaired permissions.
I'm completely baffled. Help and suggestions gladly accepted.

You should be able to remove the Plug In that is affecting Safari, by going to the Library on your Startup Drive (Not the one in your USER Folder or the one in the folder called system.
Inside you will find a folder called Internet Plug Ins, Locate the Plugin that is causing the Problem and remove it. You will need to have Admin proveleges to do this. I would move it to the Desktop to make sure you have got the right one.
After that I would do a search, for anything else related to that particular Plug in and get rid of what you find. IF you use Spotlight you may find that everything that has any reference to the words Speed Download will be listed so if you know how I would use a regular Cmd-F Search and set the Criteria to Name and Contains.
That should do it

Applet in Apple Mac OSX problem

Hi all,
have developing an applet long while using WinXP platform, everthing seem ok, but when i try over Apple Mac OSX, i has a loading problem saying that init failed to load ArrayList as error message said:
ArrayIndexOutOfBound, 0...
but when i debug print out the ArrayList content and its length, i'm sure that this ArrayList is NOT NULL and its length is NOT ZERO either. what is happening here? oh, ya, this only happen in Safari, in FireFox for Mac no problem, even Camino also pass the test, why? anyone have idea about this? because i'm new to Apple Mac.
also, there is another question whereby, when i use FireFox for Mac to load the applet, the applet load seem no problem but it just can't display properly. what i mean is that in Windows platform (IE6), this applet show entire applet successfully, but when i try it in Mac, it show only a part of applet without any error, but when i try to refresh the page, applet is now successfully show, why?
lastly, when a button of an applet being click and this will bring a new window with some parameters value, its work on IE in Windows platform, why it won't work for FireFox or Safari for Mac? i see prompt out saying is security problem, is there any workout of this? thanks. to summary out of junk above:
_______________________________FireFox_____Safari_____IE
_______________________________Win | Mac_____Mac____Win
1. load applet for 1st time___________OK_|_NO_____FAIL____OK
2. refresh applet after 1st load failed___OK_|_OK_____FAIL____OK
3. when applet button click (security)___OK_|_NO_____-_______OK
p/s: all above test was using same applet with same parameter and value.
below is the sample i capture from Apple Mac just now:

i has a loading problem saying that
init failed to load ArrayList as error message
said:
ArrayIndexOutOfBound, 0...Well, post the stack trace.
but when i debug print out the ArrayList content and
its length, i'm sure that this ArrayList is NOT NULL
and its length is NOT ZERO either. You can still get an out of bounds exception with those conditions. The list could exist, its length could be N, but you're trying to dereference position N + 5, for example.
try it in Mac, it show only a part of applet without
any error, but when i try to refresh the page, applet
is now successfully show, why?My guess is that you're not calling repaint() when you should, but that's just a guess.
lastly, when a button of an applet being click and
this will bring a new window with some parameters
value, its work on IE in Windows platform, why it
won't work for FireFox or Safari for Mac? i see
prompt out saying is security problem, is there any
workout of this? thanks. to summary out of junk
above:Often you can sign applets so they can do things that unsigned applets aren't allowed to do.
Maybe you're making some kind of security mistake that Firefox and Safari are (properly) catching but IE isn't. In any event, post the error message.

I have a MacBook Air which has a camera installed in it but it doesn't seem to work for some things like iMovie and my security camera for emergencies. It does however seem to work for Photobooth and facetime. Please write back and help my mac's problems.

It'd be nice if you could help me with my mac's problems so I can start using iMovie and my security camera again. Thank you too all that answer.

I have a carillon 25 keyboard (bad choice, I know) and I can't get it to communicate with my mac at all! I'm running logic pro 9 and reason 5. I get signal in from my M Audio trigger finger so I know it isnt an entirely mac based problem. Thanks!!!

Well, how have to determined no signal is being recieved to your mac?
Have you got something that shows the actual signal? Or have you just been trying to control a VST? What software are you using by the way?
I personnally went with a AKAI MPK25, because it's made already mapped for logic & ableton etc, so it just makes things incredibly easy.
I would suggest you return it if you can as a dead unit & perhaps look at something else a bit easier?
Otherwise, if you just want to get this working we can have a look a bit deeper.
And driver? OS X driver?

I purchased Microsoft Office for Mac through the Apple website.. I have downloaded all from the disk into my Mac, no problem with all the other Word etc, but Outlook is asking for the key number: I have put it in but its obviously not the right one...????

In the box with the disk came the product key, have put it in and it doesnt work. Please help..x

unfortunately - you can not. you can't even buy outlook by itself at microsoft's own website.
does it have to be outlook? maybe you can get away with using something else that's outlook compatible.
how about trying Thunderbird for Mac OS?
or maybe you can call apple and let them know you purchase the wrong version - they might give you a break and just pay the difference for the home and business version.
good luck

TV Guide fails - router problem?

When the guide failed on our main TV is the family room, I tried trouble-shooting it -- no luck. Then I "chatted" online with Verizon's "Raul" for two hours, trying everything he asked, including swapping the box with the one in the bedroom -- Raul thought it was the biox and gave me an 800 number to call to get a swap in boxes. However, before the weekend is over, all but one TV has the same problem. Right now, we get the guide on one TV and no guide on four TVs.
I've worked on this all day so far today. Verizon's In-Home Agent reports that none of the TVs have connectivity with the router. So I've concentrated on that, I've unplugged the router and the boxes, reset the router, accessed the router's control panel to see it seems to be working well. The only thing I can see wrong is this: The router's "WAN Ethernet" light stays dark, though its "WAN Coax" light stays lit. I wonder if this could be the problem; and, if so, how could I fix that?
One thing worries me about a router problem, though: Why would I still have the guide on one of the six TVs?
Anyone have a clue if I'm on the right track?
Thanks,
George

Yes, sounds like a router problem.
The STB has to download the program guide via the router. Each box should download 10 days worth of programing. So when the router goes out it could take as much as 10 days before the guide disappears. So the one box that still has the guide, was the last one to update and had more guide data stored than the others. It will go as well just given time.
If you have rebooted and reset the router, then the problem is either you have a bad router or possibly a bad splitter. Either way, you need to call tech support so they can get a tech out.

Mysterious routing problem / interface determination

Hi,
I have a very very strange routing problem with XI.
A message is sent from R/3 to XI and then send via adapter to an external party. The routing is configured well. But sometimes I have the following problem:
A message is received by XI (from R/3). The receiver is determinated. Although an interface determination and receiver agreement is configured, the trace shows "no interface determination fpr party xyz and service abc found". The very strange thing is that finally the receiver interface DELINS.DELFOR01 with namespace urn:sap-com:document:sap:idoc:messages is set!!
Finally, the error message is "no receiver agreement found for "... DELINS.DELFOR01, urn:sap-com:document:sap:idoc:messages", which is reasonable because this receiver interface has never ever been configured!
Any idea why the interface determination cannot be found and nevertheless a completely wrong receiver interface is set?
This error occurs just sometimes for certain partners, but not always with all messages for these partners!
Help appreciated!
Christopher

Hi,
all routing objects are 100% correct. Particularly the receiver service has definitely no DELINS.DELFOR01 interface, but nevertheless the Integration Runtime tries to send the message to this interface. Another strange thing is that in the trace there is the warning "no interface determination for party xxx and service xxx found".
By the way: The Receiver Determination was configured to terminate message processing when no receiver can be found.

Lightroom 5, Mac. Problem with the Radial Tool. Marquee Lines disappear.

Lightroom 5 Mac. Problem with the Radial Tool. I use this tool a lot. I must have hit a hot key by accident because between photos the marquee lines have disappeared and i don't know how to get them back. Without the marquee lines there I cannot rotate or expand the radial tool.

I have attempted to uninstall, empty trash and a fresh download from Adobe. The problem is still there...

Router problems. Multiple Linksys connections

I am having an issue with one of my computer connections to my Linksys WRT110 router. I am using a WUSB100 USB adapter on my HP computer with Windows Vista. I set up one connection to the Router initally and just used the default Linksys router name. It was working fine but now it is always disconnected and when I look at the connection it is connected to Linksys 2 3 4 or some other weird linksys router that are all really my Router. When I look for availible net works it lists my original Linksys router but there are all these LInksys 2 linksys 3 and Linksys 2 3 4 routers too. They are not other linksys routers in the hood they are all comming from my router. how can i get it to connect to my Linksys router only instead of connecting to these other connections that it seem to be renaming itself.

On your computer click on Start - Control Panel - Network and Sharing center and then under task click on "Manage Wireless Network" and in the preferred network list remove all the networks and then close that window... Now again in the Network and sharing center window... click on Connect to a Network and search for your wireless network and try to connect to your network... Once connected to your network check if you are Online.

.Mac sync problem

I can't sync my computer with my .Mac account. When I go to "System Preferences"->".Mac"->"Sync", the computer just sits there and I won't be able to go into the "Sync" option. I can't access the "Advanced" option in this window neither, however the "iDisk" and "Account" options are accessible.
I don't know if this related with my iSync problem reported also in this forum.
Thanks in advance.

Replying to myself as the one long discussion about recent .Mac sync problems has been locked!!
Just to say that NOW .Mac on the web says:
".Mac sync services are currently intermittently unavailable to some users. Changes made to synced information will be reflected when the problem is resolved. All other .Mac services are unaffected.
Last Updated: 6/1/06"
So the MANY people who have been posting problems in the last 24+ h MAY find it resolves and is not their end. But, customer care suggestion to apple:
- IF you think .Mac syncing has a problem POST the info IMMEDIATELY
- Possibly even email .Mac members as many use sync all the time without logging on the .Mac web services
The time and stress (cand cost) spent by many trying to fix their own syncing is frustrating. I have spent several hrs over the last 24h unregistering, registering, syncing manually, resetting from different Macs, doing it item by item...finding a glimmer of hope when on one occasion Mail synced and on another so did contacts, only for .Mac login failures to continue...This has clearly been replicated by a large number of other frustrated customers from the other postings on this over the last day.

Dreamweaver 2014.1 Build 6947 (Mac) - save problem

I updated to latest version yesterday and now have a problem when I save files which shouldn't happen on a 2012iMac saving to a thunderbolt drive - and didn't happen before updating.
When I save a file i get to watch the (very pretty but boring) spinning top for a longtime. If the 'Force Quit' window is open it shows Dreamweaver 'not responding'. Mostly but not always Dreamweaver decides to respond again.
Same site, same settings, same HDD as before the update.

What have you broke?

Hi Nancy,
It seems it's a bug, so I will go back to the previous vetsion. Thanks for
