How to diagnose what is causing occasionally 'hang' of my WRT400N?

We have lost our internet access three times since installing our new WRT400N router. I'm trying to figure out what to do the next time it happens to determine what the problem is.
I have only witnessed this once myself and what I discovered is that the router configuration was no longer accessible through http://192.168.1.1. I also noticed that the LELA software would just hang. When I rebooted the router everything went back to working just fine. The other two times this happened when I wasn't around and my wife rebooted our DSL Modem (ActionTec M1000 with Qwest 7MB DSL). This also fixed the problem.
Our network is wired up so that the router is just a link from the DSL Modem to a Switch. So, if the router goes down the rest of our internal network continues to run just fine (as long as no device needs to get an IP address).
Can anyone point me to a troubleshooting guide that will help figure out the problem next time this happens? Or does it sound like any known issues?
Thanks,
Randy.

Thanks,
I'll definitely try the direct-to-modem thing next time it happens.
Can you tell me what problem changing the MTU would solve? From what I've read, changing this should not be done lightly. It sounds like individual computers should also be updated to match so things run efficiently. Also, it sounds like XBox Live, which I use, requires a minimum of 1365.
Also, I downloaded and ran mturoute.exe in a number of different ways and it seems to be happy with the default setting of 1492, example:
C:\>mturoute.exe www.slashdot.org
* ICMP Fragmentation is not permitted. *
* Maximum payload is 10000 bytes. *
- ICMP payload of 5046 bytes failed..
- ICMP payload of 2569 bytes failed..
+ ICMP payload of 1330 bytes succeeded.
- ICMP payload of 1949 bytes failed..
- ICMP payload of 1639 bytes failed..
- ICMP payload of 1484 bytes failed..
+ ICMP payload of 1407 bytes succeeded.
+ ICMP payload of 1445 bytes succeeded.
+ ICMP payload of 1464 bytes succeeded.
- ICMP payload of 1474 bytes failed..
- ICMP payload of 1469 bytes failed..
- ICMP payload of 1466 bytes failed..
- ICMP payload of 1465 bytes failed..
+ ICMP payload of 1464 bytes succeeded.
+ ICMP payload of 1464 bytes succeeded.
Path MTU: 1492 bytes.

Satellite M30: Blue screen error - how to diagnose what it is?

I have a hardware problem but I am not sure of the exact nature. Although I looks like the hard drive or something communicating to it.
Some two weeks ago I started to notice performance problems when loading something from the internal hard drive: overall function of the computer (like mouse cursor movement, mp3 playback) became hampered when the harddisk was loading (saving was less of a problem).
This was NOT the case when loading data or executing programs from an external usb harddrive. Today I got a blue screen informing me that this crash was probably due to new hardware or software, followed by a physical memory dump and a harsh shutdown. I rebooted the computer, but got the same problem after the login screen.
Trying to start it up in safe mode didn't work either and after a couple of tries it never got to the login screen anymore -- a few seconds after boot start there was a flash of a blue screen followed by an immediate shutdown.
Anyway, I used the product recovery dvd-rom but the problem is still there, i.e. I can boot now but I get the same blue screen every hour at least (seems to correlate with usage).
Instead of running off to buy a new harddrive I want to be sure that that is the (only) problem, and not some motherboard issue or what have you.
Hence my question: how can I diagnose what's wrong with my notebook?

Generally the best way is if you have a friend with the exact same portable. You can then take out your ram, and try it in their notebook, and try their ram in yours. If the problem persists on their computer, and yours boots up, its the ram. If not, the ram is fine. Then do the same with the HDD, again, if the problem doesnt happen on your computer, but happens on theirs, the HDD is bad, if not, your either down to CPU or Motherboard. A general overheating CPU goes into protection mode and automatically shuts the computer off. You dont get an error with overheating. But if the CPU has problems processing information it can generate blue screens. One sure way to find out if the CPU is defective is to continously reboot the computer and note the blue screen STOP error. If it remains the same constantly, then it is likely not the CPU, but the Motherboard. If it constantly changes from one error to the next, and generates 3 or 4 different errors, then you likely have a bad CPU.

Can anyone help my diagnose what is causing this kernel panic?

Tried to learn how to read these from a website, but no luck. Could someone smarter than me figure this out? It's happening weekly. Thanks!

How to diagnose what is wrong with CCMS?

Which o/s are you using??
We had this problem on windows 2003, and the SAPCCMSR.00 service was not running. I started the service manually and this corrected the error.

I have an email account causes the machine to hang up after being in use for a day. It only occurs on my Macbook Pro and only one particular account. The problem account works fine on my iMac and Windows Machines. Any ideas what is causing this?

I have an email account causes the machine to hang up after being in use for a day. It only occurs on my Macbook Pro and only one particular account. The problem account works fine on my iMac and Windows Machines. I have been to the local Genius bar and through trial and error we have determined that Mail is working ok but somehow the account is causing the problem. I have used this account for years. Any ideas what is causing this?

No idea why, but one thing you may try if you have the time, is create a new user, and set up the problem mail account in the new user space. See if it causes your MBP to hang as well. That will tell you if it is something wrong with your main User, or something wrong with MBP.
Assuming this works, I'd nuke the problem account in your main user space, re-start, and reinititate the account and see if that helps.
Depening on how many email accounts you have setup, it may be necessary to nuke the whole Mail folder in your User/Library.... Hard way to get it to work, but just my idea.

E-mails with attachments, mostly photos, are replicating themselves in my inbox, 100 or more at a time. What is causing this and how do I fix it?

It is an intermittent, but a regular-enough-to-be-really-annoying occurrence........when someone sends an e-mail, to which is attached a photo of some kind, or a picture document, it will replicate in my inbox, sometimes 100 or more copies at a time. I delete all of them, empty the trash, and will also go to the Yahoo web version of my e-mail and delete the offending e-mail from there and empty the trash. Sometimes worked. Now that process isn't working, and this particular e-mail just filled up my inbox with over 100 copies of itself, even after the other steps were taken. Can't get any incoming mail.
This log jam of replicated e-mails prevents incoming and new mail from reaching the inbox.
Needless to say, am not too happy about it. What is causing it, and how do I fix it, other than to go to Outlook for my e-mail client....? :0) This, coupled with the constant "not responding" each time I try to send an e-mail, delete items from the "sent" or inbox folders, is really driving me nuts. We have a crappy internet connection, and that is likely part of it, but the "not responding" is not a new thing with Thunderbird, either.
Thanks in advance for any assistance you can provide. I dislike the web version of Yahoo, and don't want to have to switch to that, as it just doesn't meet e-mail needs. Would like to get Thunderbird fixed.

I have not seen your error in either my IE or my chrome. I do note that you are using a "strict" Document Type Declaration.
You might try a transitional DTD, which should be more forgiving than the strict:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
Other than that, I don't see anything particular (because I don't see the error, either) that would cause the menu to drop vertically instead of horizontally.

On a Mac running v10.7.2, the only way to reinstall Safari is to reinstall OS X using OS X Recovery.
Safari 5.1.1 is for Snow Leopard. It will not run on a Mac with v10.7 installed.

I am using an iPad with Apple TV and airplay with a projector in my classroom. The mirroring cuts out and back on several times during use. Any suggestions on what's causing it and how to fix it?

I am using My iPad with Apple TV, Airplay and projector in my classroom. The projector screens blanks out and back on several times during a presentation. It seems like a problem with connection but I'm not sure as it comes back on after a few seconds. Any idea of what is causing this and how it can fixed?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased.

You can not access the backup directly.
Did you restore your replacement from this backup?
If so then you already have everything in the backup on your device.
If not, you can wipe the device and restore from this backup:
Settings > General > Reset > Erase All Content & Settings
What is it you are worried about losing that isn't already on your current device?

How do you determine what is causing a reoccurring kernel panic?

What is causing and how do you fix a song stopping during playback? I have latest iTunes 12.0.1 and Yosemite 10.10.1.
It stops then after several seconds (like 25 secs) then it starts again ... and then several seconds later it stops again!
I have the latest software so I don't know what to do?

How do I find out what is causing a random black screen on iMac?

Hello I get random black screen on a iMac and I haven't made any hardware changes. How can I find out what is causing this?
Thanks
Jer
iMac 2.66 core 2 duo with Snow Leopard 10.6.8

You can do an SMC and PRAM reset. These won't hurt anything and 'might,' maybe help the screen issue. If it doesn't, then take it into an Apple store or AASP for their guidance and advance testing diagnostics.
SMC:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.
PRAM:
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

What is causing Premiere Pro CC to hang?

The issues I'm experiencing never seemed to happen to me when I was on CS6....I'm on a mid 2011 iMac 3.4ghz i7 with 16gb of RAM and the AMD 6970M GPU with 1GB of VRAM and I'm editing ProRes 422 footage. My apps and OS are all on a recently added SSD.
But a few things are happening on Premiere CC (7.0.1) that are driving me nuts and I don't know what's causing it:
1) First, if I have two sequences open and I don't go to one for a while, when I do go and open that tab it hangs for about 15-20 seconds. The render bar is red and I can't scrub through any of the clips as it appears to be loading or something. Then it suddenly clicks in, the render bar turns yellow and I can edit away like normal. What is causing it to hang like that? I don't remember this ever happening on CS6. Is this a hard drive thing (eventhough my new scratch drive is 3x's as fast)? Or maybe a GPU Acceleration thing or a VRAM thing since before on CS6 I wasn't GPU Accelerated since my card isn't "officially supported" although it does ahve 1GB or VRAM? Or is this a Premiere Pro CC thing and I just have to get used to it? Or something else? When I'm in "software only" mode the render bar stays red since my footage is 60fps on a 24fps timeline, but with GPU acceleration the render bar goes yellow and makes it noticably smoother to scrub, etc.
2) Similarly, when I'm editing for a while and I add the gaussian blur effect, the program hangs for another 15 seconds or so before I can scrub or play. It doesn't happen when I first start up PPro, but usually happens more frequently after I've been editing for a while. So why is it hanging? I'm guessing #1 and #2 are related but again, I never experienced this 15-20 second hang time on CS6.
At one point tonight, the app actually froze up after adding a gaussian blur and I had to force close. My auto-save wasn't working for some reason either (I had it saving to Dropbox) so I lost about an hour of work since I had last hit save. Frustrating.
Anyone have any ideas or ways to find out what is causing this? Any solutions?
A little back story and specs: Recently my scratch hard drive crashed so I got a newer much faster hard drive, plus I installed a SSD into my 2011 iMac to run the apps off of. The app loads fast and for the most part editing is fairly snappy and I can keep the Preview window at Full resolution with no stuttering when editing ProRes422 footage. I can also take advantage of GPU acceleration now on PPro CC because my iMac has 1GB of VRAM (eventhough the card is not "officially" supported (AMD 6970M)).

Nothing jumps out, but I have a routine that I do whenever Pr acts up, which is way too often:
1. Trash Preferences (fixes most Pr problems when "it's just not working right").
2. Delete media caches and previews (ditto). Do this after each application crash or hang.
3. Check for corrupt media in your project. That can cause major performance degradation, freezes and crashes. Remove or transcode problem media to some other format.
4. Reboot the computer (Pr has RAM leaks) or much faster, open the Terminal, and type in "purge" (no quote marks) and hit Return every so often. You can tell you're out of RAM when you open the Activity Monitor > System Memory tab, and there's no Free RAM left. Free RAM defaults to the green color. A lot of blue (Inactive RAM) is caused by Pr. It's RAM that's not accessible. Low RAM causes performance issues, and I'm gobsmacked that Adobe hasn't fixed this problem yet. Purging will turn the blue Inactive RAM into Free RAM. The longer you work in Pr, the less Free RAM becomes available.
Those things clear up 99% of my problems.
5. Run Disk Warrior (esp. if you're getting beach balls, AND every time after a computer (not application) crash or freeze).
6. Re-install the application.
7. If you have an external video (BMD, AJA, etc.) or audio card that requires third-party drivers, remove them and see if the problem vanishes.
8. Re-install graphics drivers (this has fixed display issues for me, such as video not updating in real-time).
I know that's a lot of stuff, but I make my living using Pr and Ae, and it's vital I keep them working and don't encounter any job-stopping problems.
A lot of people suggest Repairing Permissions, but this is mostly useless advice. You only need to do that if you're getting directory access denied or can't write file errors. However, it can't hurt.
