The wifi on my macbook has slowed to a crawl. What is up?

I have been all over message boards tying to figure this out... Now I'm hoping to find a nice person who can walk me personally through this solution.
I have a macbook 2009 and the internet is ridiculously slow all of a sudden!
To put it in perspective, my 15 year old laptop gets 40mpbps per second and the Mac maybe gets 8 on a good test!
Wow!
I have my router configuration page open, no idea what to do.
I've checked my settings(against a couple other forum responses) they seem fine,
I hit option and clicked on wifi and I see
Transmit rate 130
Mcs index 15
Rssi -28
Chanel 11 (2.4gz)
(I can also see 15 of my neighbors routers around me when I click wifi)
My activity monitor
Memory free 984mb (almost half of the circle is green)
Usage 137 used, 112 free
Please let me know if you need any other info.
I called xfinity, and they reset the router yesterday, that did not help.
Mine and my kids ipads are also connected and speedy
I greatly appreciate the help!!

I just changed the wireless channel to 11....
Well it worked for about 30 min... My speed was way up to 30mps.
Now it's back down, I changed nothing.
This is so weird

Hi ..
Not enough free storage space can slow your Mac down.
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage. Make sure there's at least 15% free disk space.
Freeing space on your Mac OS X startup disk
OS X Tips Where did my Disk Space go?
Check to see if the startup disk needs repairing.
Launch Disk Utility located in HD > Applications > Utillities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If Disk Utility reports errors, restart your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities in OS X Recovery to repair the startup disk.
Make sure to back up all important data first before using OS X Recovery.
Anti virus software, as well as third party Mac cleaning utilities such as MacKeeper and CleanMyMac can also slow your Mac down.
For Safari.
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Relaunch Safari to test. if that doesn't help, troubleshoot Safari extensions.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test.
If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.

The screen on my MacBook has been flickering and shaking up and down. It starts flickering, shaking, gets 'pixelated,' then eventually begins to fade to white and freezes. Restarting sometimes helps, but only temporarily. Why is this? How can I fix it?

The screen on my MacBook has just started flickering and shaking up and down while I am using it. The screen starts flickering, shaking, gets pixelated, begins to freeze, and eventually fades to white. Why is it doing this? How can I fix it?
It is a newer MacBook, just over 1 year. It is well cared for, hasn't been dropped, etc. I don't want to pay for expensive repairs for such a new computer, and I certainly can't afford a new one!
I've tried updating my system like the Support page suggested, but no improvement. The problem started just the other day, and is progressively getting worse.
.... as I typed this, it did it again. Only, this time it did not flicker and shake, but got 'pixelated' (pixels came up checkered-like darkened and lightened). It did this for about 2 minutes and then stopped after I did not touch the computer.... Now it is flickering... HELP!

it means that it is not a hardware issue. Other then that, Im not too sure. Sorry I can't help you any further, but Im sure others members of this forum will read your question and be able to help you. Good luck

The screen on my macbook has malfunction. When I change the brightness to zero and return to the first level of brightness it works briefly but then the screen starts to flicker brightness and quickly extinguished.

The screen on my macbook has malfunction. When I change the brightness to zero and return to the first level of brightness it works briefly but then the screen starts to flicker brightness and quickly extinguished. It seems to be a bad contact, it would not be normal for a quality product that should have, he has less than two years of use. Not because of the bad use or crash. Someone with the same problem or can help me? It's really a contact problem? I've done all the procedures recommended by the online support. Thanks.

Hey everyone in Apple world!
I figured out how to fix the flashing yellow screen problem that I've been having on my MBP! Yessssss!!!
I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
I followed the instructions on this page and here's what I did:
Resetting NVRAM / PRAM
Shut down your Mac.
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 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.
I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process. Since I did that, my MBP boots up just like normal. No flashing yellow screen anymore!!
(Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
Let me know if this works for you!

That depends on which OS your MacBook can support. The system requirements for Mountain Lion 10.8 are here...

The spacebar on my macbook has something under it and I don't rust myself to remove it. Can they clean it in an Apple store? If so, do I need to drop it off or can they do it while I wait?

MacBook Pro Slowed to a CRAWL after less then a week....

Hello All,
I'm new to Mac. I just got a MacBook Pro last week.
Well, for some reason it has slowed to a crawl....
The dock show/hide and magnify isn't working either. Neither is the "active screen corners" feature on the dashboard. In addition to that, the system does not highlight menu items and show the submenus.
Also when starting applications they take forever to load.
It's acting like it has no ram even though it has 2 gigs and a 2.16 processor. The ram is showing up in the "About this MAC" screen though.
I've tried turning off all startup login items. Nothing is being loaded into memory. I've also tried running the disk utility.... still having the same problems.
I'm new to Mac so perhaps I'm missing something completely obvious.
What would you all suggest is going on, and what do I need to do to fix it?
Thank you
MacBook Pro Mac OS X (10.4.6)

James:
I suspect Wizard's problems resulted from too many widgets and possibly some not quite compatible software. Slowdown can result from lack of free physical RAM, so that Virtual Memory swap files on disk have to be frequently accessed. I don't think he mentioned how much RAM is installed. His symptoms go beyond mere slowdown, however, so I would suspect other software problems as well.
Cutting way back on widgets together with restarting can work wonders sometimes.
OS X handles file fragmentation pretty well, for file sizes up to about 20 MB. It's probably not necessary to run defrag on a Mac unless one wants to clean up a large space for video work. I don't have defrag software. I'd rather wipe the drive (maybe once a year) and reload from a backup drive. I do swear by DiskWarrior, however, and hope they release an Intel version soon. DW does a great job of correcting disk and file errors and optimizes the directory.
Apple has been packing a lot of changes into OS incremental upgrades. To interpret that as comparable to Windows Service Packs probably isn't very accurate. Yes, some bugs are fixed but there have been steady upgrades of core features. Security fixes are often included as well. But I've experienced no stability problems whatever.
Some users recommend using Combo updates instead of using Software Update. I've always used Software Update and have never had a problem. The important thing, either way, is to make certain the operating system and disk directory are 'clean' and trouble-free before and after the update.
I've never had to do an OS reinstall except once, when I was tinkering with System files and slipped up. Routine preventive maintenance works.

Can't seem to download any app despite entering the correct password and answering 3 security question but still in the end it comes up the message that my session has timed out no matter what! Please help, many thanks in adv!!

Try doing it on your computer with iTunes and then sync to your iPad to see if it clears the problem.

The wifi on my macbook pro (lion) is ridiculously slow. the wifi on my pc works perfectly though. how could i fix this?

So I recently bought my MacBook Pro, about three days ago, and the wifi connection is horrible. I can barely access anything on the internet. I tried using my PC laptop, and the wifi worked very quickly, so the problem definitely isn't my wifi connection and has to do something with the MacBook Pro. What would be the problem? And how would I be able to resolve this problem?
By the way, I am using the OS X Lion and this is my first Mac ever.

I think the other devices are fine. I'm not sure. It usually only happens like a couple days out of the week. I do know that the network I'm using when I click on the wifi symbol at the top of my screen doesn't have a padlock on it. It IS MY network that is at my house, but maybe that has something to do with it.

Why has my native windows 7 Pro-64 network to a windows 7 Pro-64 VM has slowed to a crawl and freezes, after the new Arris cable modem was installed?

Please appreciate the details, so the complete situation can be visualized:
The office network:
New Mac Mini PC running Win 7Pro 64, (in boot camp), networked to an iMac running the same Win 7 Pro 64, VM, UNDER Fusion 7Pro.
To review: My treatment rooms former dell PC/running vista business/ running the server and network versions of my Dental practice mgmt & X-ray capture apps, had no probs WLAN to the front desk iMac running the same PC client dental network apps under the same vista business, & Fusion 4. The dell slowly fried its power supply .
I could not wait to replace it with a Mac mini/ boot camp/ win7 pro 64 bit, as it has to run natively to capture X-rays. The front desk iMac was also upgraded to os10.10.3/ Fusion 7pro/ and its own matching Win7 pro 64bit. The iMac is wired and WLAN connected to a netgear d600 router and a Time Warner Cable modem. The modem then failed and was replaced by an arris modem. As the Arris was configured out of the box, the network ran much slower slowed, as compared to the original modem. BUT- The Vonage 2 line phone system stopped working- no incoming or outgoing voices could be heard after it rang. Then twc remote configured it and the phone now works, but the network iMac slowed to a crawl, and now freezes when accessing the Mac Mini PC dental server to edit or enter data. The Mini perfectly accesses the internet via wifi. It accesses the front desk canon printer by wifi, and can print share they the iMac that is wired to the printer, as well, BUT, the network connection is a spinning pinwheel. The front desk imac easily finds the Mac Mini PC server on the network. It connects easily by entering the servers IPv4 address SHOULD THAT last value change. But if data isn't entered in slow motion, the window and app freezes, and has to be force quit by Task Manager!
Cause:
1. I think TWC switched the cable modem from the default- Non Bridged, to Bridged mode. Could this be the cause?
2. The network setting in fusion, on the iMac is auto detect, a setting that always worked with vista and with the new Win7 system, before TWC installed the new arris modem. 3. Switching to NAT does not work at all is there a different setting to use?
3. Does the Netgear Router have to have a port or pref configured so as not to block the Server.
4. might in need an Access Point (I have an extra netgear wdr3400) ).
5. Do I need an Extender that plugs into the AC LINE?
I hope this info helps.
PS:(some addtl info:
1. File sharing works fine between the minis -Mac and boot camp sides and between the iMacs- Mac and VM sides and between eother side to or from either of the 2 computers! 2. Also either office computer and all of my my home macs , (& my iPad, & iPhone), can access each other instantly and flawlessly, with splash top streamer and jump desktop remote apps, as controller or as client! In fact, the front desk iMac can remote control the mini PC AS IF YOU WERE DIRECTLY ENTERING INFO I TO IT!
SO I think it's either a misconfiguration in the TWC cable modem &/or some additional pref to config in the router? Thanks so much for your help, (been using VM's since VPC1. & Win95 in a iMac, 1999, DV MODEL! (TWC BLAMES VONAGE FOR NOT OPENING SOME PORTS IN THE TELE MODEM. Vonage blames TWC FOR NOTopeningj ITS PORTS IN THE CABLE MODEM, when they meant the ports on the Netgear. They have passed the buck for 6 weeks with not even a guess at what to do. VERY FRUSTRATING! Again, thanks to all!

Okay Saint Steven, I'll bite:
I read your description multiple times, very carefully, and I am still confused. May I suggest the following:
* Follow basic troubleshooting procedures. Isolate each individual problem. Don't try to get everything working at once. Make one change at a time.
* If I read your description correctly, the Netgear D600 (??) Router is the office LAN (not WLAN). Connect each piece on the LAN separately one-by-one, and test each piece individually. Get your LAN and its devices working first. Forget about the Vonage and the Arris Cable modem.
* Next, look at your Internet connection. Again, try each piece separately. Depending on how the original cable modem and the new Arris cable modem are configured, you may also have to adjust the configuration of the Netgear D600 Router.
* Finally, if you are still having problems, try to organize your thoughts and presentation before you post again. List each element in your network. List how each element is configured. Be systematic.
"Arris cable modem" does not help much - some are simple bridges, others are routers, etc.
To answer your questions:
1. I can't tell from your confusing description, but I don't think so. It seems like the problems are associated with the system changes you made (replacing Dell, etc.) and the problems seem to be isolated to the local LAN.
2. Auto detect should work, but it is easy to change and test, as long as you change one thing at a time.
3. No. The Netgear router should allow all communications on the local LAN. Could you have put the "server" in the DMZ?
Note: I could not find a Netgear "D600" model in a web search. Do you mean N600?
4. No. I doubt that you need an additional access point. Based on your description, everything appears to connect to the LAN.
5. No. See 4.
To repeat myself:
* Do careful, systematic troubleshooting.
* Provide carefully written, detailed description of your network and system configurations when you ask for help.
Good luck!
