Permanently Change MTU in Airport - no running scripts all the time?

I was hoping some amazing Mac guru of networking could help me permanently fix my MTU on my Airport extreme - it seems to love a packet size of 1100, anything else in combination with this new Netgear wireless N router and I get HUGE latency. I play World of Warcraft and need to have a solid connection, and don't want to have to type sudo ifconfig en1 1100 into the terminal every time i wake up my computer. i've read some of the other threads and even hacked the library to change the MTU setting on startup, but i don't want to have to restart my computer every time either.... any suggestions on a permanent MTU change? thanks!
alternately, does anyone know of another wireless N adapter besides the Extreme (which is just G) that will work with a mac? i am thinking maybe a new adapter will let me permamnently change its MTU settings or just work best automatically with my netgear router.

Ryan, please don't misunderstand, but there are several people that are all hep't up on the development of the 802.11n technology.
To date, this technology is still in the development stages and has not been implemented. So it is really a waste of time and money until this technology is implemented. The last vote that was taken only produced 47% of the 75% required to implement. So the best you can get to date is 802.11g.
It is sad that many users here about the new developmet and then the manufacture's way in and start working on there product, but until the technology is implemented these routers do absolutely nothing, to increase your signal speed.

I have a Time Capsule on which I back up 2 MacBooks and on my wife's machine she keeps having Airport Utility popping up all the time with a yellow button flashing on the left and a Red button on the right side with a "1" in the middle of it.

I have a Time Capsule on which I back up 2 MacBooks and on my wife's machine she keeps having Airport Utility popping up all the time with a yellow button flashing on the left and a Red button on the right side with a "1" in the middle of it. Can any one tell me what is wrong. I read where when the yellow light was flashing there was a problem, but I am a novice at this and have no idea where to turn. It seems to be backing up on a regular basis.

On the Mac......
Open up Macintosh HD > Applicatons > Utilities > AirPort Utility
Click on the Time Capsule icon, then click Edit in the small window that appears
Click the Network tab at the top of the next window
Change the setting for Router Mode from the current DHCP and NAT to read Off (Bridge Mode), then click Update at the lower right of the window, and wait a full minute for the Time Capsule to restart to a green light.
Then.....very important
Power off the Time Capsule and your Arris modem/router for a few minutes
Start up the Arris first, and let it run a few minutes by itself
Start up the Time Capsule next the same way
Your network will now be correct, and your printing capabilities will improve.
If Time Machine backups do not occur now, post back and we will tackle that next.

Airport losing my Network all the time

Good morning,
I have set my network several months ago, it was working perfectly fine in the beginning. Now, this is what is happening all the time: after about half an hour being online, it seems like I am not hooked to the internet anymore. The Airport light is green, the signal level is at the highest, the status says "connected", but if I try to access a page, the bar is blank. No other networks show but if I manually type another network that I know of and that is not password protected, it connects to it, and then I can access my page with no problem.
This is not my network, I don't see why I should use a neighbor's network when mine is just set in the same room as my desktop, and above all why I can't catch it with the Airport that seems to say everything is there.
If I want to go back then to my own network, it has disappeared from the list, and then it says it can join back. It takes sometimes half hours before I can join back as if nothing had happened, and then some time later it does it again.
Any idea why it would do that? is my airport box defective?

Thank you for your help, Tesserax, I really appreciate it because I admit I am very annoyed (it is getting worse today, or I am less patient because of my own moods, but it seems to disrupt me from working so much).
I have many other networks, but mine is always with the strongest signal. Sometimes it drops to 50% (the highest is around 85%) and the noise increases (the highest has been 40%), and I see no of the described reasons why. All the other networks that appear are all around signal 44% and below
The only electric cable is the computer cable and the cable from the computer to the printer, could it be that making the interference? there is no way I can hook these somewhere else! The airport is hooked to the modem box and that's where the cable is hooked to my home, so I also do not see how I can avoid having those together. Maybe there is something I haven't understood there.
Also I have not understood how I can change anything in the airport. All those numbers seem to be automatically generated, and I don't see where you have a menu that gives you control to how it is set, if I have to reset something, whether it is in the System's preferences (network) or in the Internet Connect, I don't see any setting menu.

Does my library computer have to be running iTunes all the time?

I was able to get home sharing set up, but unless I keep iTunes running on the computer my library is on, the other computer can't see the shared library. Any way around this, as I really don't feel like keeping iTunes running on my machine all the time?

I'm with Limnos. In my experience, iTunes has to be running on the computer you're trying to share from. (It's okay if it's minimised, so long as it's on.)

Can I keep my iMac running at all the times?

I have iMac, early 2009 version and in good condition. I would like to know, whether I can keep the machine ON at all the times ( 7 * 24hrs) or should I switch it off every night? So far, I am switching it off every night and switch it on the next morning. Please clarify me.

In talking with a tech guy at Applecare, I was told to shut the iMac down--all the way down--every so often. I'd been using "sleep" for months and months, but this chap said the processor is running at about 10% capacity in sleep mode. It was then accumulating signals, loading up the RAM, and slowing down the computer. If you shut down the computer from time to time--stopping the processor completely--the accumulated "noise" is erased, and the computer will run faster as a result.
I've used a lot of vague language here. I'm not sure exactly what happens when you use sleep mode for extended periods, but in following the tech's advice, my mac is running fast and smoothly.
So I'd say, DON'T keep your machine running forever.
FWIW.

G505s running hot all the time

So I have my G505s (still under warranty thank god) and has been running fine but now it seems that the fan isn't running anywhere near the percentage it should be. I have run energy management fan cleaning, bios is updated, AMD overdrive is downloaded... but it is physically hot and the fan does not change rates of speed. Yes, the power management setting is set at active... I am not even running anything and it is running hot.
Is there a driver or patch that alters the temperature protocols? Because if the fan can run faster, but isn't even when it is hot.... then it isn't serving the purpose.
Lenono please help me... and the fact this is a consistent problem isn't prompting me for reccomendations. If this continues I will be getting the laptop serviced under warranty or replaced because this is ridiculous.
I do run windows classic shell, but that has not been a problem yet.

hi reedbarnes,
Welcome to the Lenovo Forums.
Just to check, when you open AMD Overdrive, what are the values on the CPU frequency and temps?
- Sample image
In addition,is the system running on BIOS v3.00? Looking at the BIOS 3.00 - Summary of changes, this should fix the fan duty if you're getting CPU temps. between 50-90°C.
If you have the BIOS to v3.00 and you're getting high temps (eg. 60°C++) after logging into Windows and there are no startup apps / processes running on the background that's eating up high CPU resources then it's likely that the fan may need to be replaced (or the thermal paste and heatsink as it's not properly conducting the heat out of the APU). In this case, you may need to contact lenovo and report the issue as you may need to send the unit for service.

After Mavericks Install, MBP runs hot all the time

Im sure this has been said all over the community but I have to add my two cents. My 2011 MBP was perfect on Mtn Lion. I started the update which failed on install, which I then had to wipe the HD and do a fresh install. My time machine backup wouldnt even restore, that was a fun night let me tell you. Anyways, ever since I installed Mavericks, not only do I have the service battery issue everyone else has but now even running firefox or watching a movie will make the laptop run super hot and the fans start going. Ive even had the MBP shut itself down twice b/c of the overheating. Example: I almost couldnt even get time machine to make a new first time backup b/c the laptop starting running hot during the backup and it shut itself down. The second attempt worked but it sure seemed like it was on the verge of shutting down again. I just tried resetting the SMC but I dont think it did anything if you want my honest opinion.
I hope apple is listening and realizes what mess mavericks is making of our older macbooks.

I did do the verify/repair disk, and there is nothing wrong with the disk. Havent had a chance yet to boot in safe mode. Will post an update shortly but in the meantime:

New MBP seems to run hot & fan runs almost all the time

I've had my MBP for just about a week now. It's the new, 15", 2.2 GHz model. It's great, but I notice that it runs hotter than my Powerbook G4 did and the fan is almost always on. It's presently sitting on a wooden topped table. My house is not AC-ed, but the air temp is about 70 F/21 C today. Seems to run hot in my AC-ed faculty office too, when I am there. What is "normal" for this machine. TIA.

David,
Ditto what Ned says. To be sure, 80 C is not too hot (it is the temp that the MBP is designed to maintain as a working maximum), but that you are experiencing this temp at all times indicates that something is pushing the processor at all times.
That is not normal. As has been suggested, have a look at Activity Monitor. If you are not doing anything of any consequence at the time, your CPU usage should be very, very low, and processes that you see using CPU intermittently (there will be many of these processes) should only use a small percentage when they use any at all.

How to stop Airport turning itself on all the time.

My AirPort setting (MBP) keeps turning itself on at random. I have it always switched of as I am connected over a cable. It is a random occurrence, sometimes not for days and than 3 times in one day.
This happens since upgrading from 10.4 to 10.5.
Wake for administrative purposes is switched of.
Any idea as to why this should happen? fixes? etc.
Maybe it is the plist, but I do not know where it is kept, anybody know where this is kept and what its name would be? Or any ideas for that matter.
thanks

Hi Nick
Failing that you could trash it. You'd have to set up your networks again, but that might not be such a bad thing.
did that before and it did not solve it, so...
Have you tried running the hardware test that came on the DVD/CD with your computer? Just to check the Airport card?
No I did not. will give it a go.
Reboot with the disk in and hold 'D'.
I hold 'C', is 'D' new? suppose C = CD and D = DVD?

Is it bad to have the fan running loud all the time

the fan on my macbook runs loud and long at times. is this bad for the machine?

Is it possible to have 2 threads running at the same
time at different times eg 1 repeats every 20
miliseconds and the other 40 for example. Yes.

I reset SMC and now fan is running high all the time

I reset the SMC after finding info on here about the built-in iSight not working. Once it came back up the iSight is working, but the fan is on high all the time. I'm not sure what to do with this. History prior to resetting SMC: I hadn't used the camera since the hard-drive was replaced in October. However, my kids have used it to video chat via stickam with no problems yet iChat and Photo Booth wouldn't recognize the internal camera (System Profiler could see the camera). So I tried the fix I found on here - resetting the SMC. It fixed iSight but now the fan is on high all the time. Any thoughts on what I should do next?
If you need more info on the iMac - I can supply that later as I am away from that computer at the moment. Here is what I do know - 20" white iMac

Hi, an SMC reset is one of the things usually recommended as a possible fix for loud fans, not the cause. There are a few troubleshooting steps to take, but you'd be better off posting in the Intel iMac Forum. You are in the iMac G5 Forum. You have a newer computer. They'll try to help you over there.
EDIT I'm basing this on your SMC reset, which would indicate an Intel Mac. Sure it wasn't a PMU reset?

MacBook (2008) fans running most of the time

Hi!
I have a late 2008 white MacBook. Recently, my MacBook's fans have started to run almost all the time, even when usage isn't very heavy. Currently, as I'm writing this post, they are running at 6115rpm, CPU is at 69 degrees, Airport card at 61 degrees, and CPU usage is constantly at around 40%. I have a messaging programme on, I am writing this post and watching a Youtube video at the same time, which doesn't to me seem to be particularly heavy usage. However, the fans are constantly running.
The fans kick in pretty much instantly these days, whenever I play a Flash game, watch a video or do Skype. Not forgetting a combination of browsing and messaging.
My question is: is this normal? I understand that as MacBooks go, mine is starting to get a little old. However, it is in stellar condition, and the battery health is still at 90% with 671 cycles. Is there anything I can do? I want at least another year or more of quality life out of my MacBook until I plan on buying a new one, and am willing to try saving the fans on my MacBook!
Any help is much appreciated!

Hey Tiia Hurri & welcome to the forums.
It's absolutely normal for your fan to kick in very quickly if you're video chatting or viewing any kind of Flash content. You'll probably see a higher CPU temp as well--all normal.
Your computer only has the one fan. You're doing a very good job by keeping an eye on the temperatures. You probably have nothing to worry about unless you notice the fan has stopped coming on or you see it running when you having nothing CPU-intensive going.
Unfortunately, YouTube does fall under that "CPU-intensive" category. My fan kicks in whenever I watch a YouTube video.
I wouldn't worry about getting another year out of the computer--it sounds like your machine is doing very well & that should continue for a while.
The one thing to watch is your battery's health--anything over 300 cycles can mean your battery will abruptly stop working, so keep an eye on this.

the fan always runs, usually you cant hear it. Right now my fan is running at 1996RPM and I would know it was on unless I checked.vv Is is running loud all the time?

Permanently Change MTU in Airport - no running scripts all the time?
