Internet speed just went ALOT slower. WHYYY

I have no idea about computers.
BUT
i use airport.
I have Unlimited download.
and my internet download speed was really fast ever since i had this computer (about a month)
but now its got really slow.
any ideas of whats happened?
My wireless network is Exacly the same.
So i think its my Mac.
Virus?

Spencer, you've asked your question in a forum intended for questions about the server version of Mac OS X. I'd suggest you ask again in the Mac OS X 10.5 Networking forum. You'll be more likely to get useful assistance there.
But no, it's extremely unlikely to be a virus. There have as of yet been no confirmed Mac OS X viruses.
Regards.

My internet speed suddenly went VERY slow on all browser

I am running on a Mac OS X Lion 10.7.5, 2 Ghz Intel i7, 4GB Ram DDR3.
I am experiencing very slow internet speed after some system update some time ago.
I have tried using wireless and LAN cable but both results the same.
I've tried resetting routers in both my office and home but it is still as disappointing.
Kindly advice on what to do? I've forgotten which update is it as it is some time ago already.
I have installed bootcamp in my macbook and tried the using from windows but there isn't such issue. The internet was smooth and great.

Try these basic troubleshooting steps.
1. Quit all app scompletely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
2. 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.
3. Go to Settings>Safari>Clear History, Cookies and Data. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

My internet speed just slowed down big time!

Hello everyone,
About 5 or so days ago my browsing speed just got so slow. I can't effectively view streamed media anymore and downloads are far too slow. I have a 1.83 gHz 15.4 Macbook Pro with 1.5 gigs of ram and maybe a week after a full system reboot my browser just got slow. I was using camino and thought maybe that was the deal but safari was also slow as balls. I have high speed wireless internet here and the other PC's in the house run at normal speed. Techtools shows everything is in order. Is there anything else I can check or any settings I can change to get my speed back? All my software has been updated.
Aaron

I find that by rebooting once a week, everything stays working , including internet connection times, smoothly. I have noticed the RAM usage is at a higher level prior to the reboot and more RAM is available after the reboot. Using Firefox, the other day I was unable to log into my e-mail account; rebooted and the the log in went as expected.

Internet speed in Snow Leopard slows down because of connected External HDD

I have two external Iomega harddrives that I connect through FireWire 800 to my MacBook Pro 17".
I noticed, when the harddrives are plugged in, safari lags and slows down tremendously. As I eject my harddrives from my MacBook Pro, the internet miraculously comes back at normal speed. The harddrives are just mounted, no data is being transferred.
I am not sure why this is, or why external harddrives would bother my internet connection. I am connected through my Airport wirelessly to my home router. Other computers get wireless internet fine as I notice this problem with my MacBook Pro.
Anyone know why this is happening and how to stop it? I notice restarting sometimes helps, but this problem comes back after awhile.
Also while I am mentioning this, I also notice the internet slow down when the MacBook Pro runs on battery. Anyone know why this is, and how to fix it as well?
Thank you, and Happy Holidays to all!

I do not notice any connection between my external harddrives being connected and internet connection no more. So that is good.
What I have been noticing though, is my MacBook Pro at some points loosing connection to the internet. The Airport icon in the menu bar says it is connected to my wireless internet at full reception. But at times Safari and Firefox are just not working. I try reseting my internet routers and the problem still exists. It comes down to me having to restart my MacBook Pro, which seems to fix the issue.
I have a iBook G3 with Tiger, and a Dell laptop with XP, and they both receive wireless internet fine when in use. And this is while my MacBook Pro is not.
I am not sure what the issue is now. Right now I'm not sure if there is anything I can do to fix this besides contacting apple and using my applecare.
Is there any internet connection problems similar to what I just described I should be aware of? Thanks in advance!

Internet Speed Terribly, Consistenly SLOW... Despite "Good" Test Speed Results!

Internet has been terribly slow since we got FIOS Internet (75/50mbps) installed here half a year ago.
YouTube clips, Skype and even our NetFlix streams are all choppy, and inconsistent. Doing searches on Google, Yahoo, or Edmunds would take 3 to 10 seconds...which we all know in 2014 is completely unacceptable.
I have done my homework validating all the potential failure points. I am in the software industry since 1999 and have an expert knowledge in network, databases and systems integration in general. Everything that can be checked, have been done. I've followed all your suggestions on the website, but in vain.
I'm connecting to the FIOS router from several different devices (PC Laptop, MacBooks, iPhone and iPad) wirelessly about 3 to 30 feet away. No microwaves, no fridges, no baby monitors, no thick walls or doors obstructing. Apple TV and WD External HD are unplugged.... yet the internet is SLOW. Ran the Speed test over the past weeks and months, and I always 'score' pretty good....50/35 or 65/40mbps etc. The numbers are impressive but do not reveal the real performance! Back in our old home in Brooklyn, my scores were the same (using Verizon FIOS - same service/speed)...but the speed lived up to the Speed Test results. Had no problem over there.
Can anyone help me? What am I missing? Any special tricks of the trade with this Verizon FIOS internet service?
If this is not getting resolved very shortly, I am ready to escalate this to the management level at Verizon.
Please advise. Thanks everyone for listening.

The best way to find where the problem is without using test gear is by the process of elimination.
Test you LAN using LAN Speedtest. First test using Ethernet connections and see if you can get speeds of 90+ Mbps. Much higher is possible if the equipment you are testing with has gigabyte capability at both ends.
If you can't 90+ on your LAN there is a problem with your LAN setup that needs to be addressed.
Then you can test speeds on your LAN using WiFi.
Using Speedtest introduces to many additional variables making it very difficult to diagnose throughput problems.
Once you know that your LAN is up to standard then you can point at Verizon.

Speed on PC alot slower than on mobile devices

Hi, I had infinity installed today and am achieving 75down20up on all of my mobile devices. However my PC will not get over about 38 down and 15 up. This is despite me trying wired/wifi and powerline adaptors.
Any advice? I am a fairly competent PC user so have troubleshooted as far as I can and I am getting inconsistent at best results.
I would put this down to the connection stabilising over the first few days but that doesnt explain why mobile devices are consistently achieving 75/20.
Any help would be greatly appreciated

Use this speed tester then carry out the further diagnostics and post back a screen shot of all the results including your IP profile for up and down. This test must be done with a wired connection.

As you will have a Homehub 5 can you also post the stats from 1-12 by logging onto the Homehub management pages then troubleshooting > helpdesk. http://bthomehub.home/

Airport Extreme (time capsule model) internet speed EXTREMELY slow.

Hello, first thank you for any help on this as it is a bit frustrating for me.
I recently noticed my internet speed was running significantly slower on both my MacBook Pro and on my wifes MacBook.
I had my ISP come and check out the problem. They hooked my MacBook Pro directly to the modem and my speed went from under 1 mb to over 5mb.... he then had me hook up directly to the lan port on the airport extreme and my speed was once again back down to the 1 mb range. He concluded that it must be a problem with the speed once it hits the Airport Extreme.
He ended up giving me a different modem, its a 2wire wireless. I have since connected my airport extreme to the new modem and am still pulling down the same speed, but now I have connected directly to the new 2wire wireless modem and am getting my 5 mb speed.
Can anyone give me any help or advice on what I can do with my airport extreme time capsule so that I can get the speed I should be getting from it.
Thanks again.

More information. I have a separate router for ISP connect/DHCP. I only use my Airports to create a WDS and bridge onto my home network. I have never allowed 2.4GHz or 5GHz phones in the house, just to limit interference. I live way out in the country so interference from neighbors is negligible to nonexistent. Speed testing done with Speakeasy.net/speedtest
I moved all the hard wired machines from the TC to my switch. Which will impact the speed of my backups, but it helped with internet throughput for those machines.
Then I split my WiFi into 2 separate nets, each with a connection to my home network switch. I created a b/g network with my ufo Extreme and my Express (NET 1). I left my TC set for n/b/g (NET 2). As long as my MacBook was powered off internet speed were nice and fast. As soon as I turned on my MB the speeds were impacted, not as bad as before.
I then changed NET 2 to be n-only 5GHz and retested. These was a small but noticeable impact for wireless machines but I have concerns because my ISP is wireless and runs at or near 5GHz.
I then changed NET 2 to be n-only 2.4Ghz and retested. Again a small impact for wireless machines whenever my MB was connected to NET 2.
I then had my MB join NET 1 and speeds were nice and fast all around. My solution, shutdown the wireless on my TC and use it as just a network drive while I use my old reliable b/g hardware for WiFi.
Maybe someday this Draft version of 802.11n will be finalized and have no issues.

VERY slow Internet speeds

During about the past week my internet speeds have been VERY slow, sometimes loading a 1 minute youtube video has taken upto 5 minutes, and i also have been disconnecting off the internet very frequently. We have had bt internet for about 3 years and this has never happened before. We have a BT home hub and all our computers connect to the internet wirelessly. I have spoken to a friend and he said he had the same problem this week, he said he phoned up and got sent a new hub. I am not sure if this is the problem but all advice is appreciated. Thanks in advance. I live in dundee (Scotland) if its any help.

Geoff,
I think Angus has either a Home Hub 1.0 or 1.5 as the front screen when you access the router settings page show "My Broadband Connection" and lists the speed and all the other pieces of information on this screen. Would I be right Angus?
In terms of the slow speed issue you are facing. Please can you post the information on the Home hub screen under "My Broadband Connection" so we can see the results.
Also, the general troubleshooting steps for slow speed would involved moving the Home Hub, if not already there, to the Master/Test socket.
Pleas see the following link for information on how to do this:
http://bt.custhelp.com/app/answers/detail/a_id/13892/c/346,4740,4740
You may also want to run a speed test, as Geoff suggested ecm200 did, via http://speedtester.bt.com, as the results from this test can be used by technical support to raise a fault.
I know that some people think that because they have been connected to the same socket for a certain period of time, and the connection/speed has never changed, that the socket must be Ok, but if this socket is an extension socket, the internal wiring may have degraded over time and this is the cause of the poor speed. This is why technical support always ask to go to the Master/Test socket, to prove that the fault is on the BT Network.
I reckon, at worst, you will get an engineer to visit, who will either fix the fault, or recommend that the Hub is replaced. However, the troubleshooting steps will have to be completed before you get to this stage.

Slow internet speed with Site-to-Site VPN

I have 2 RV042 routers, one is version 1 and the other is Version 3 and both have up to date firmware loaded. Both ISPs are cable, one is Comcast and the other is Mediacom. I have set both MTUs to various different settings and set the upload download speeds in Bandwidth Management. Speedtest.net shows speeds at office # 1 of 30/5 and office # 2 is 10/2. The VPN connection is always active. My problem seems to be this, if data is ever being transferred between the offices the internet speed for office #2 slows down to 1.5/.12 but there isn't really any notable differences at office #1. Does anyone have any idea of what could cause the drop in speed.

This makes perfect sense depending on the size of the file. Bandwidth is limited to the speeds you stated, no matter what resource is using them--internet or vpn. Also, a large factor is that with asymmetrical bandwidth that when a lot of upload bandwidth is used, the download bandwidth suffers as well.
I bet most of the time when this happens, the file is being transferred from office #2, thereby using up all the available upload bandwidth.
Office #1 won't see the effects from file transfer because the file transfer is using download bandwidth not upload bandwidth.

Internet speed significantly slower using Time Capsule

I have a 50MB internet connection and a Time Capsule. I use the Time Capsule to wirelessly connect my iMac to the internet. I also have a desktop PC with an ethernet connection to the Time Capsule. Lately the internet speeds have been very slow when I connect via my Time Capsule. I experience slow speeds from the wireless and wired connection. On speedtest.net, I can't even get the test page to load. On my PC, when I unplug my ethernet cable from my Time Capsule, and plug it directly into my modem, I get fast 50MB speeds on speedtest.net. When I plug the cable back into my Time Capsule, the speed is slow again.
Does anyone know why the Time Capsule is causing my internet speed to be significantly slower than connecting directly to the modem? And more importantly, how can I fix the issue?
Thanks, Brian

Hi Brian,
Every couple of months I also experience the very slow wi-fi connection through Time Capsule (currently on firmware 7.6.1 but the problem has occurred also with older firmwares).
I have been able to fix the slow connection this way:
Test your laptop's wi-fi speed to verify the problem. For example, I'm getting only 2 MBit/s download speed at speedtest.net when the Time Capsule slows down, although my operator provides super-fast 100 MBit/s connection.
Detach the (Internet) Ethernet cable from the Time Capsule.
Connect the same (Internet) Ethernet cable directly from ADSL or Ethernet wall plug to your MacBook (or any other computer that experiences the slow wi-fi connection).
Run the Speedtest.net test again. Now you should obviously get "full" Internet speed without Time Capsule (for me it means about 75 Mbit/s, never quite the same the operators promise ;).
Detach the Ethernet cable from your laptop and connect it back to the Time Capsule (wait until the green light on Time Capsule). Test again with Speedtest.net. (Now I get around 60 Mbits/s over Wi-Fi, that is OK). Interestingly the problem now disappears and stays fixed for several weeks or even a few months, after which I simply repeat this process when needed.
I am currently running Time Capsule firmware 7.6.1 but the issue has happened on later versions also. Perhaps you will experience it after running 7.5.2 after a few weeks or months?
For background information I am running on the same Time Capsule's Wi-Fi network:
A white MacBook with OSX 10.7.3
Samsung laptop PC with Windows XP
Two iPhones (3 and old 4)
Playstation 3
Apple TV
Hope this helps!

DSL internet speed

I am starting to think that Verizon is Throttling down our Internet speed. I have checked with friends around our area about slow Internet speeds ( dial up or slower ) Every time we contact Verizon our speed goes back up only to slow back down again in a day or two. We only have DSL available and we pay for the fastest speed available to us.
A am collecting information on this before I go to my state representatives and public utility commission.

YES we have been around and around with people that we can hardly understand. We unplugged and turned off , reset and all the other things from the verizon script on many occasions We have been told that our modem/router was outdated and received a updated one. The speed picks up and then back down to a craw in a few days. I have ask around and it IS a common problem but not all at the same time. We are starting that Verizon is charging us for the higher speeds and throttling the Internet speed down. We have contacted our State Representative at a function last week and her staff will contact the PUC to find out some awnsers for us. We live in a rural area and customer service from many businesses is nonexsistance

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting?

Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting on the computer, and how?

One possibility is that you may need to "Upgrade" your Cable /DSL Modem if you have an older unit. ISP's that provide your Internet service in recent years have been switching over from DOCSIS 2.1 version Modems to DOCSIS 3.0 version Modems, which handle the new higher data streaming speeds the ISP's are offering. I would suggest you call your ISP's Technical Support and inquire about this possibility.

Internet speeds keep slowing down to a crawl

I'm having a problem that has only developed in the past week which was during a time when I haven't changed any configurations in that period of time since my son was born a week ago yesterday and I obviously had more important things to do than mess with my network configurations. However, about 2 weeks prior to his birth, in the process of configuring a baby monitoring system with icam source, 3 weeks or so ago, I read that I might be able to improve my internet performance, I ran googles namebench a couple of times and added and re-ordered the DNS servers that had been listed prior to any problems developing based on its' reports. My internet speeds improved as a result of changing those DNS settings and stayed good until the past week. But of course, we now need to use the computer as part of our baby monitoring system and it's not working worth a **** and I'm getting frustrated since I can't put my finger on the problem and I don't really have time to spin around in circles right now. I'm sure it's probably something simple and I can't put my finger on it though. Sleep deprivation is new to me.......
I've kept running log of notes so this is a little deshoveled but I figured the more information I provide the better the chance someone might help me get this solved quickly.
In the last week, since my sons birth, my internet speeds would be okay after restarts and resetting everything, 2.5 Mbps or so but after a 10-15 minutes it starts to slow down to .2-.3 Mbps. I went thru all my network settings, restarted everything, repaired permissions, I've changed ethernet cables reset PRAM, firewall is running, stealth mode enabled, allow signed software incoming connections and my various other programs such as netsessionmac4f3c6b, skype, java, itunes, etc.
All sharing services off and pretty basic login items at startup including growl.
I had AT&T come out and check my DSL line and everything checked out on their end up to and out of the DSL modem based in their equipment tests.
The problem seems to start when I connect my imac (a fairly loaded 27" imac I got in Dec.) First off, as soon as the imac is connected to the modem via ethernet, the old ethernet modem flashes and continues to flash, even right after startup. So the tech thought something was running in the background and I can't figure out what. I looked through login items but don't see anything that would be a problem and am afraid to eliminate everything.
So I created a guest account to eliminate any login items (I think) and in I got 5.69 Mbps right off the bat. But after a minute or two, without changing anything my download speed slows down and I get for example .77 Mbps. The same thing happens with my administrator account on the imac. Fast speeds at startup and more importantly if I change the configuration by switching between ethernet and airport, I get fast speeds right after changing the configuration but after a minute or two I am well below 1.0 Mbps. I've got several network configurations with automatic, airport and ethernet set up in different ways including a clean ethernet connection with the original DNS settings.
I haven't set up an airport only account but that really isn't the way I want to hook up the computer that sits right next to the modem and runs my network. Restarting the old modem and direct connecting the computer to the modem results in the same thing happening.
I connected my ethernet from the (old?) modem directly to my ancient powerbook G4 and I got +5.6 Mbps download but it also slowed down to 300 kbps after 5 minutes or so the first time (old modem?)
Now to explain why I have "old?" listed above. I was then able to get a new DSL modem from AT&T, hook it up just fine, get enormously faster internet service in the 5,000 kbps only to have it slow back down to around 300 kpbs after connected for several minutes.
directly connected to imac-bypassing router
3,500 kbps
after 15 minutes-250 kbps
connected to imac thru router/time capsule with airport extreme
2500 kbps
after 15 minutes=166 kbps
directly connected to an older powerbook G4 with new modem
IP address of 192.168.1.64
5.65 Mbps on speedtest
after 15 minutes=5.67 Mbps
after 30 minutes= 5.59 Mbps
1 hour-5.66 Mbps
Very solid, stable readings for what I am used to. This would seem to isolate the problem to the imac.
directly connected to imac with new modem
IP address of 192.168.1.64
5.8 Mbps on speedtest
after 30 minutes= .60 Mbps-ping takes 250 ms
1 hour= .46 Mbps-ping takes 250 ms
Now a problem that only started last night after I hooked up the new modem and started up my old Time capsule/airport configuration, I got a message that said something to effect of "another device on this network is using computer IP address 192.168.1.64. So I tried manually changing last digit of the IP address on the computer to one number higher and it kept saying the start and end range were incorrect so I shut the airport station down since when it was connected, it would not allow the computer to connect thru the router via ethernet. I did a hard reset on the airport and I got it back up and running just fine but the internet speeds on the imacs' ethernet connections are so slow it's practically worthless. I also checked to see what was connected to my airport on any given occasion, 2 iphones, 2 pads, another imac running upstairs and a newer powerbook running icam source that is supposed to be the baby monitor. Except for the laptop everything can use "802.11n" but the powerbook only connects via 802.11g so I have set the airport to that limiting setting.
Any suggestions? Is there a way for me to log what is happening so I can report in more detail?

First thing is to check if the wireless is on a sensible channel: HomeHub doesn't always make sensible choices. Install inSSIDer on your laptop and see what other devices there are around and if there is any clash. Also, try moving the HomeHub around a little, even quite small differences can make a big difference to wireless signals.
You could run an ethernet cable from downstairs to upstairs. Easy to do, but can be a bit unsightly. If most of your devices are upstairs, you could use this cable to connect the modem to the HomeHub. If you have devices both up and down, you may want to keep the HomeHub downstairs and add a switch upstairs.
HomePlug may be suitable for you. If you search Amazon for HomePlug you will see a couple of kits for just over £30. Don't go for an 85Mbps one. A 200Mbps such as the TP-link or D-Link should be much better than wireless, but not as good as a cable.
Depending excatly how many devices you want to connect and where, you can pay more and have a builtin wireless at one end: http://www.amazon.co.uk/Devolo-1408-Wireless-N-HomePlug-Adapter/dp/B00472MMCQ/ref=sr_1_15?ie=UTF8&qi... Or it may be best for you to use the basic devices and add an old wireless router in switch mode.

Windows 7 64 Bit Very VERY slow internet speed

I just bought two new laptops for my wife and I and we've been having terrible trouble with download speeds since taking them out the box.
We are using the exact same configuration and IP as before only our last two computers were on XP and Vista but there were no issues whatsoever. I even went and bought a new router just in case that was the problem but it made absolutely no difference, leaving
me with the conclusion its a problem with the 64 bit version of Windows 7.
Currently I cannot even watch a Youtube video because after loading the first couple of seconds, it stops loading and then after a couple of minutes there's a quick burst of speed and stops again.
I can't complete a speed test on my connection on either laptop. Normally this would take only a few seconds but the site (speedtest.net) crashes every time using windows 7.
Setup;
Windows 7 64Bit
Intel i3 2310M @ 2.1Ghz
4Gb of RAM
My IP is VirginMedia UK on a 10Mb connection (same problem wired or wireless)
As you can imagine this is very frustrating since I have just paid out over £1000 to find my browsing experience has virtually at a stand still.
Any help in this matter would be very much appreciated

I recently had the same problem after installing Windows 7 64bit. The internet speed for some reason was really slow. After looking for a solution I tried to flush the DNS. It worked.
Open start menu
type "cmd" in the search then hit enter key
when the new screen opens type:
ipconfig /release
hit enter and then type
ipconfig /flushdns
hit enter and then type
ipconfig /renew
hit enter and the problem is solved.

Internet speed just went ALOT slower. WHYYY
