Did OS 10.9.1 gum up internet speed?

Computer at work (Verizon is ISP, DSL) and another 2 machines at home (cable isp), both Firefox and Safari are incredibly slow even though Speedcheck seems OK (6600 at work and 15,500 at home!). Gummed up since OS 10.9.1 update after noon today. Oh boy!

Each of these systems runs WiFi through last year's Airport (1,2 TB), if that is helpful
Oh, and each was running Mavericks 10.9.0 til afternoon today...

Last night I rented a movie successully (Argo) but it would not download. Support was called and I was advised that it was probably an internet speed issue. This was confirmed when I did a speed test as suggested. They now want to sell me some software for $40.00. Help

Hi,
No, it was Apple. Last night the movie (Argo) was downloaded. It took about an hour, however it did not open.
I can watch the preview, but can't open it.
Thanks for your interest.

When I downloaded Firefox, it did not copy my Favorites List from Internet Explorer

When I downloaded Firefox, it did not copy my Favorites Bar from Internet Explorer. If it did, I don't know where to find it on Firefox. Can you help?

Look for a folder named '''from Internet Explorer''' in your bookmarks.

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.

Absurdly slow internet speeds and often unable to ...

I'm used to getting around 13 Mbps Internet speeds from BT.
In the last few days, although the speed tests show similar results (assuming I can actually get online to test them), Internet browsing has become painfully slow, with many pages simply not loading at all.
I've called BT, and been through some tests with them, and they assure me that everything is fine, and that my Internet speeds are as high as ever.
I've also done some hunting around on google, and tried using open DNS settings, but to no avail. It's especially hard to upload data, and it's almost impossible to send email.
Occasionally, if I turn on my Mac after a longish break, I can get online easily, and send e-mail for a few minutes, then the problem returns.
BT insist that there's nothing wrong with the line, but the fact that the problem affects both my Mac and my iPad suggests that the problem is not with my computer.
Indeed, I'm now in the local pub, and everything is working just fine.
I've been through all the usual things - checking location of Homehub (even though it was absolutely fine for 18 months in its current location), changed the ADSL micro-filter, changed the wireless channel, etc, and to no avail.
What else can anyone suggest?
Thank you.

So, the first time I did this speed-test was on my return home, when everything was working fine again.

Verizon is Capping Internet Speed/Service for "Unlimited" Customers

Some recent news has been brought to my attention by Verizon Wireless' customer service department, and I think that given the severity of Verizon Wireless’ continued breach of contract to Internet customers, this matter should be brought to everyone else's attention as well.
I originally purchased a Verizon Wireless USB Internet Card in 2007. I was offered a plan that entitled me to an “Unlimited Internet Usage Allowance”. I kept the same wireless Internet device for two years and never acquired any issues or concerns. On January 20th, 2010, I went into a Verizon store and was offered a free upgrade to the new MiFi Mobile HotSpot. I was told that I could test the product for 30 days to make sure that it worked to my standards and my Internet needs. It worked perfectly. I used it for multiple computers in my home, as well as work and travel.
My problem with the Verizon MiFi began on October 21st, 2010 when my Internet suddenly became extremely slow and unable to access any web pages without minutes of waiting. I continued to call customer service and go into the Verizon stores throughout the month in hopes that someone could find a ‘glitch’ and solve my issue of what soon became No Internet access. I did all this with patience and good faith, as I have continued to pay $60 a month for “High speed 3G” service. Two weeks ago, I took the MiFi device into the store and requested a new device since it became entirely defective. My new device arrived in the mail and I have still spent the last week going through the ring-around circus of Tech support and the only logic they can come up with is, "Either the device is defective or my computer is too old." This is not the case, as I recently purchased a new laptop.
What I discovered was that Verizon neglected to inform me for the past two months that I had gone over my "undisclosed usage threshold" (Even though I pay for Unlimited Allowance) and now my internet speed has been capped and I am unable to access the Internet. I spent 4 hours on the phone yesterday and weaved my way into a small department called "AIT" which is supposedly a new sub-contracted company that is suppose to help negotiate my "situation". They of course are closed, and my numerous voice mails will most likely never be returned.
At this point, I am still paying for something that does not work, and Verizon has taken it upon themselves to decide "how often" I can use the internet. This was not disclosed to me in my contract that I signed in Jan 2010, when I continued my Wireless plan for "unlimited usage allowance."
I want everyone to be aware of this, before they head out this holiday season and spend hundreds of dollars on a Verizon Wireless Internet Device, and eventually will have to deal with the same nonsense I'm currently going through right now!

I started with one of the few unlimited plans back in 2008- They kept telling me to "hang on to it- cause it won't be around for long!" So I did and when I upgraded my device- everything worked great for 7 months. I started using it more frequently as a hot spot for more than one computer, we're talking email, web browsing and paying bills- Not Xbox360 for 24 hours a day or fownloading 10 videos a day!? I don't even know how to do that!?!
And the first month we went over- we got capped! Now it runs at about a quarter of the speed. Which was never disclosed to me. And to think- they market this MiFi 2200 as a hotspot for up to 5 computers??? I can only imagine how quickly people are being capped.

VBA Internet speed

Hi I'm new to this type of scripting however know a bid of VBA and MSaccess. However this is my first project using WMI.
Did a function with pingstatus that went well.
I'm now trying to measure my internet speed on this PC and get the value in MSaccess. I searched around and can now find at least my network adapter.
Function nw()strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2")
Set colItems = objWMIService.ExecQuery( _
"SELECT * FROM Win32_NetworkAdapter WHERE NetConnectionStatus = 2", , 48)
For Each objItem In colItems
Debug.Print "-----------------------------------"
Debug.Print "Win32_NetworkAdapter instance"
Debug.Print "-----------------------------------"
Debug.Print "Name: " & objItem.Name
Next
End Function
Now what I like to do is get the mom. speed on that adapter
The same as what you can see on the "windows task manager/networking/networkutilization"
I tried every property in the win32_network adapter but can't find the right one.
All help appreciated.

It is not on the adapter. The utilization is a performance number. Run Perfmon and look at the network data.
Counters are an advanced element of scripting. Search for examples.

Internet speed is slow with Mountain Lion 10.8.2

Internet speed is slow with Mountain Lion 10.8.2, but booting in separate drive running 10.6 is fine. Tried renewing DHCP, zapped the PRAM, ran disk utilities, and sudo chron. No change. I am running 2008 Mac Pro, 8 gig ram, AT&T DSL via ethernet. Getting 0.15Mbps instead of 3Mbps.

Did you try creating a new location and deleting the old one? Just renewing the DCHP on its own may not be enough. Follow all the instructions here, first:

Internet Speed even after an engineers visit.........

Hi,
I am hoping someone can help me as I seem to be getting nowhere.
Whilst I was away this last Christmas my telephone went faulty (No dial tone although I could still use my BT Broadband at its usual 6.25mbps speed – it had been this speed since I moved in approximately 3 years ago). When I returned home I reported it to BT and an engineer came to visit on 3rd January. He repaired the phone but my internet speed plummeted down to 0.45mbps download and 0.14 upload. I was told I needed to fault this separately.
I thus reported this to BT (in India) who said he could see there was a problem and he would try to reset it. However I would have to wait 5 or 7 days for the line to ’settle’.
As it never got above 0.41mbps upload and 1.7mbps download over this period I recontacted BT in India who said they would put the job out to Openreach and an engineer’s visit would be needed.
Despite Openreach missing an agreed appointment last week, necessitating me to recontact BT in India, an engineer finally attended today.
The engineer agreed the internet speed was only 600kbps at the main socket in my house. He then went to the exchange to check the speed there which he reported was 8.0mbps which it also was at a cabinet further down the road. He then checked the speed at the telegraph pole opposite my house and the speed was only 700kbps there. The engineer stated there was obviously a problem in a stretch of about 40 yards of cable between the cabinet and the telegraph pole. However there were no working ‘spare pairs’ to transfer my line onto.
He then dropped the bombshell that BT do not guarantee line speed on the internet, only that the telephone side of the line works and as my phone was working there was nothing he could do, other than report it back. He then went onto say though, that as my line ‘passed its phone test’ and the phone was working, BT would not replace the faulty cable and so I was stuck with the problem.
He said until the cable fault caused an outage of someone’s telephone, BT would not replace the cable.
Hence I am now left with snail pace broadband. Surely this cannot be right?
Many thanks
Solved!

I'd be interested in knowing what was done to improve the speed.
Hi,
The engineer changed all the wiring from outside of my house to the BT main socket as his equipment was showing a problem there. Then he went out amongst the cabinets and manholes in the area and found I was 'cross paired' or something with another phone line further towards the exchange. He also connected me up to a different 'pair' that he found in the alleged faulty cable and on his equipment it showed I should then receive asbout 6 to 7 mbps (despite a section of cable being aluminium instead of copper!!). He then rang BT to take off a 'throttle' or something and lo and behold my speed was back in excess of 6mbps. It took the engineer almost all day (out in horrible cold and snowy weather) to fettle it but it is great to be back upto speed again.
He did say it would take about 10 days to finally settle down but I was expecting that so no problem there.
It was a great job done by a very thorough and precise engineer in order to find the fault(s) that were causing the problem.

Linksys WRVS4400N V1.1.13 slows down Internet speed by 50%

Hi,
Recently I upgraded my Internet speed at the ISP from 10Mbps to 25Mbps and the problem is that I am measuring only 15Mbps using speedtest.net.
On the day when the tech came out to install the new DSL modem, he noticed the difference and as part of troubleshooting, he bypassed the Linksys router and voila the net speed measured 25Mbps using speedtest.net.
So, why my Linksys WRVS4400N V1.1.13 acts like a bottleneck in this case? I didn't have this problem at the speed of 10Mbps. The upload speed is OK, it is 5Mbs with or without the DSL modem.
Does someone have any idea how to troubleshoot this problem?

Hi Tom,
Thanks for the tipp on disabling the IPS, I did it and the speedtest.net test resulted in 21Mbps.
So, it is already a great improvement.
It is interesting though, that on the IPS page of the router, all four protocols were disabled (http, ftp, telnet and rpc), so I am not sure if it was doing anything useful anyway. Am I right?
Since the tech from my ISP was using speedtest.net for testing and did get 25Mbps, I figured that it should work for me too. I am not sure if our ISP has a website for the same purpose.
In order to eliminate any bugs I was considering upgrading the firmware on my router, but I am not sure which firmware I should use, it seems to me that there are two sets of firmwares available for my router one with VPN version 1.xx the other one is VPN ver. 2.xxx
The model# of my router is WRVS4400N v1.1 but I am not sure whether to upgrade to one or the other VPN version is up to me or the VPN version range is already set in my router and I cannot upgrade to 2 from 1 in case I have VPN v1. (How can I tell which version of VPN I have on my router?)
8 hours later I added this text:
I did another test on speedtest.net and at this time I got 24.35Mbps, so you were right, speedtest.net won't give you a reliable speed value if you just run it once and you want to make a decision based on that. (Btw., I contacted our ISP, they don't have a net speed measuring website within their own network.)
So, I am done with the speed problem thanks to your right on target suggestion, but could you please, answer my other two questions:
- Was the IPS in my router doing anything usefull to me since all 4 protocolls were disabled - until now?
- About the firmware dilemma.
Thanks.

Non-Flash based internet speed test sites for touch?

I'd like to test my internet speed directly from my touch. It seems like the speed test sites out there that I've found (like www.speakeasy.net/speedtest)use Flash which won't work with the touch. Does anyone know of any internet speed test sites that will work on the touch's Safari browser?

Great! Thanks for the info. The results seem to be lower than normal though. I could not get over 768k even with my 1.5mb cable connection here at home. I did find this site: http://i.dslr.net/tinyspeedtest.html which seems to test more accurately.

After updating to 4.3 I can't connect to wi-fi because the "internet speeds are too slow". How much speed does this require?

After updating to 4.3 I can't connect to wi-fi because the "Internet speeds are too slow". So what speed does it need?

I called tech support and I got the same **** canned response, backup and reset to factory settings. Yeah right! Everything was fine until Verizon shoved the software update down my throat. I finally unchecked the box in Wi-Fi settings for auto network switch. However, I still get the "Your Internet connection is unstable" warning no matter what Wi-Fi connection I hit.
In a related story, I received a new or refurbished phone as my original SIII had AC/charging connection issues. I called probably three times to attempt to back up my data, went into two stores in attempts to have them transfer the information over, and all were too incompetent and inept to assist me. Only when talking to someone about this Wi-Fi issue, did someone actually know how to back up everything. Of course by this time, I had to send the new phone back because Verizon charged me $400 before I got everything squared away. What a colossal waste of my time!

Bad fluxuation in internet speeds but usually arou...

Hi,
I have been with BT for a few months now and the internet speeds have been fluxuating a lot with the norm download speeds being that stated above. Im using wired through a homeplug. Quoted realistcally between 2mbs and 6mbs. I recently did a tracert to bbc and the result was below. My line has been tested and apparently there are no faults with it. Getting really frustrated with BT's customer service and thought the community would be better help, thanks!

Internet browser freezes after checking internet speed/bandwidth

After installing Lion I tried to determine my internet speed by using various websites like speedtest ,speedtest.net and some more like them.
Every time when the download test was finished and the upload had to start the browser stopped.
It did not react to any commands. Only thing to do was a restart of my iMac.
This happened with Safari as well as Google Chrome.
With SL I did not have this problem.
Anybody an idea what causes this and how to cure it?
peterwillem

Could the setting of the firewall cause this?
I activated stealth modus.
