Very slow 3G speeds with internal card on Vodafone network: solved!

I'm running the internal 3G card on the Vodafone network in Australia (ThinkPad x200s, Vista) and a couple of weeks ago it slowed right down to less than dialup speed for no reason, and the speed hasn't picked up since.
I finally figured out how to resolve the issue today. I downloaded the Vodafone Internet Connect utlility and now my Internet speeds are restored to 3G speed. However, if I use ThinkVantage Access Connections utility to connect to the Vodafone HSDPA network, the 3G speed crawls again. It appears this is a bug in Acess Connections utility and I'm not sure why it appeared (probably related to a Vista update).
Anyway, if you come across this issue, you should download and connect using the Vodafone Internet Connection utility, which contains many handy features including a usage meter and SMS features.

By process of elimination I realised that the only cause of the sudden slowness must be software that I had installed recently. The only software I had added was a wifi utility to detect available networks--open or protected. Unlikely as it sounds, quitting the utility (which I had set to load on startup) made a dramatic improvement in performance.

Very slow download speeds with ATT U-Verse

Hello,
Experiencing very slow download speeds with Macbook Pro 2011, on Lion, and ATT UVerse Max, which should allow for an avg. 11-12 MBPS speed. Instead, I get a fluctuating 60-370 kbps speed. I am not experiencing this problem on my Windows machines (Laptop running Windows 7 and Desktop on XP), it is only affecting the Macbook pro. I wonder if this issue is a known problem with ATT U-Verse and Macs, I spent hours yesterday with their support online and they couldn't help me, stating that from their side all settings were OK; the first representative from ATT re-booted the router remotely and that seemed to work for about 10 minutes, and then it went back to a crawling speed...
Any suggestions welcome!
Thanks

Do you have QOS enabled in your router? Did you try plugging the win7 laptop directly and check the speed?

Help : very slow connection speed with AEBS and iMac

I connect to the internet using my newly purchased AEBS. I have a MacBook and an 24" iMac ( purchased in Nov 2007). My iMac showed very slow connecting speed of <1 MB/s download; with my MacBook placed just 1 foot from my iMac, the MacBook showed an amazing download speed of 20MB/s. If i connect the iMac to the AEBS using ethernet cable, it can get a very high speed.
So, where is the problem??
I am new to wireless, please help. I use iMac more than my MacBook at home.
Actually, i did not touch the any of the advance setting of the AEBS.

You know, I am experiencing the same problem. My wife's PC and iPhone are blazing fast, but my MacBook is accessing the internet at about dial-up speeds. Very frustrating and I haven't yet found the culprit.
Anyone???

Very slow download speed with intermittent halts

Need some help.
I run Apple os/x latest version and have since yesterday begun to experience constant very slow download speeds.
I have rebooted the router and I have reset it. I have tested with wireless and wired into router. No real change.
The results are below and are pretty consistent no matter when or with what computer I test it with.
This is very frustrating and I would like to know if anyone has experienced this and if there is anything I can do before calling for service.
Thank you in advance.

Very slow transfer speeds with external hard drives through Firewire and US

Hi All,
My external drives transfer very slowly on my MacPro. I've been searching for answers and have turned up very little. Apple support suggested I post my issue here. Just to make a note, I measured my disk speeds with both AJA System Test and copying files between drives and reading the Disk Activity in Activity Monitor.
I have 3 external drives, all MyBook Premium or Professional, 1x 500GB, 1x 1TB and 2x 1TB in RAID 0. I had them on Firewire 400 and the RAID 0 2TB one on Firewire 800. My transfers on FW were all around 24MB/sec on all drives (much less than what I should be getting with FW400). I then read somewhere that the FW bus on the MacPro uses the slowest speed connected for all FW connections. So I unplugged everything but the FW800 Raid 0 drive and my transfer rate jumped to 40-60MB/sec. This is much better, but still about half or so of what I expect it should be producing from an external RAID 0 setup.
To keep my FW800 backup drive faster, I've plugged the other two into USB2.0. The transfer speeds on both drives are now hideous, around 10-15MB/sec. This is so slow, but I'm not sure what to try to fix my speeds.
The HD's in the external drives are all 7200rpm, and all should be transferring at a higher rate. Do you have any suggestions or ideas? Ideally I'd like to get everything transferring at rates they should be transferring at, but I'll settle with my current FW800 speed of 40-60MB/sec if I can get my other two drives transferring at a non-snail pace.
Is this a common issue? I can't believe I'm the only one plugging multiple external hard drives into their Mac Pro. I hope someone has a fix or solution for this. I'm all ears!
Thanks in advance.

Hi Kappy, thanks for the information.
So I rejigged my setup a tad. My RAID 0 is still FW800, the second drive is back on FW400 on the back port, and the third is USB 2.0 on the back as well.
It's interesting to note that I saw the FW800 taking a bandwidth hit if the FW400 drives was being read/written to. For example, if I was averaging 50-60MB/sec on the FW800 drives and copy something large to the FW400 drive, each drive averages out to about 30/MB second, roughly half the FW800 speed I was getting. The USB while the slowest didn't cause any slowness on the FW drives.
Here are my Xbench results. These results are from each drive being benchmarked individually with no other drives being tested at the same time.

Very slow transfer speeds with Airport Extreme and MacBook

I have been using a new Airport Extreme without problem at my home for the past six weeks. The speed and range was excellent with both my MacBook Pro and the MacBook which I purchased a few weeks ago. I came out to Greece with both laptops and a new AP Extreme box for my home network here. After set up I noticed that internet access was lethargic on the MacBook and file transfer between the two computers was extremely slow. The problem seems to be with the new MacBook (although it was working well in London). I've done some speed tests and the internet download speed is only 48 kpbs! I also notice that the range is very poor--in the room next to the router I am down to five bars. If I connect to the AP Extreme with cable I get the full 1Mbps I would normally expect here in Athens (ADSL nominal 2Mbps). The MacBook Pro has no problems with wireless access speeds or range, so I am assuming this has to be a problem with the AP extreme card in the MacBook. Is there anything I have overlooked? Perhaps something to do with setting up the new AP Extreme here in Athens?

By process of elimination I realised that the only cause of the sudden slowness must be software that I had installed recently. The only software I had added was a wifi utility to detect available networks--open or protected. Unlikely as it sounds, quitting the utility (which I had set to load on startup) made a dramatic improvement in performance.

Very slow download speed with Airport Express

Hi.
I've recently experienced painfully slow downlink (download) speed using Airport Express.
My WiFi configuration:
- main router: WRT54G connected to my provider (speed limit: 4Mbit up/down link),
- AirPort Express with WiFi N and Airtunes hooked up to stereo in living room,
- AirPort Express WiFi G and Airtunes connected to stereo on bedroom.
Second Airport is currently not used to simplify tests and description of my problem.
The problem: when connecting from MacBook to Airport Express I can't reach more than approx. 512kbit downloading from internet, usually even 300kbit, while uplink reaches easily 2.5Mbit (limited probably by my network provider). While connected to WRT54G I can get 2.5 up to 4Mbit downlink, same when using cable directly plugged in to WRT54G.
I tried changing channels, switching different options in Airport with no effect - still getting pathetic download speeds. Even worse - browsing experience is awful, with frequent slowdowns, etc.
I tried different encryption methods, and seems like only switching it off at all (unprotected network) seems to let my Airport work on full speed (2.5Mbits symmetrically up/down, up to 4Mbits - provider speed limit) - which is unacceptable, I refuse to set up and use unprotected network at home.
Problem is clearly in Airport or in interaction between Airport and Macbook. I've just ran out of ideas - can you help me?

I can't offer any help with your problem except for the fact that mine has recently done the exact same thing. It's ridiculous, for months and months it was extremely fast and then all of a sudden it takes 20 minutes to open a simple browser page. Something is definitely wrong with the airport because all other wireless internet connections from other routers are as usual. \

Very slow download speeds with new laptop with windows seven- WRT160N Router

Just bought a new Laptop with windows 7 and of course wireless. Download speeds are horrible (0.2 mbs) and upload speeds are normal for me ( 8mbs) Have a wrt160N Wire less router. Older laptop and desktop work fine with normal( around (8mbs) downloads and uploads.
How do I fix this?

Do you have QOS enabled in your router? Did you try plugging the win7 laptop directly and check the speed?

My Jetpack 5510L says that its connected to 4G but its performing very slow, I removed the sim card and did a reset of the device. Any other suggestions?

I don't know who you would contact at Verizon to verify this, but I suspect you are in the same situation as me. My unlimited Jetpack is now being throttled to a basically useless speed of .10Mbps. Sometimes as low as .04Mbps. Turns out this is done purposely as they are evidently eliminating unlimited. They're doing this now even though accounts still display on the my device page as unlimited. They have given no warning, no explanation and started it in the middle of a billing cycle. At least for me. Be prepared to pay about double for 20GB with I think and $8 per gig overage cost. With the 5GB plan it appears they just throttle down to an unusable speed. Currently considering saying goodbye to Verizon myself. Even with some need to change plans and eliminate unlimited this isn't the way to treat customers during the change.

Very slow broadband speeds

Hello
My first post, and I'm hoping that someone will be able to help me with this.
For a few days now, I've been experiencing very slow broadband speeds (100kbps or less), in contrast to the 1.5 - 2Mbps that I would usually expect to get. I've been on hold to BT technical support for some time, and have got through twice, on both occasions being told that this is a widespread issue and to wait until the next day. However, I'm not seeing any improvement. I'm aware of the problems in Edinburgh and the North of England,but I'm in East Anglia.

Deej.

Once a line is stable and working well, it's best left running 24/7
Interventions like resets, replacing accelerators, unplugging the router etc. will cause line "flapping"
And the dslam sees this as instability, and in turn the BRAS lowers the IP profile ....
This is done to achieve stability, and decrease throughput purposefully, all done automatically.
What you have to do, is cure any line noise, plug directly into the master or test socket behind the NTE
faceplate, leave it connected and wait for the throughput to increase.
Very often a rock bottom IP may need a kick to get it out of the doldrums.
Eventually the noise margin will decrease, sync will increase, and IP profile go up.
Depending on how long the line has suffered impulse noise, will determine the time for SNR to come down.
Regardless of which type of phone you used to test quietline ... hum or crackle is a no-no.
It may be the cause of the problems. It could be REIN on the network portion of the connection or dslam
crosstalk, either way it needs to be reported as line noise before you can count it out of the equation.

Very Slow Download Speed

Hi,
I am experiencing very slow downloading speeds, when I am just normally downloading something in Safari, or downloading a torrent with upto 100 seeders.
The maximum download speed I have seen on my computer is 80kb/s, which is painfully slow for downloading the Adobe trials, when they reach about 1gb.
I have a router, connected to 2 computers, and speedtest.net has told me that my download speed is 1mb/s.
It seems like download speeds are being restricted to 80kb/s, so is there any way to 'unlock' full potential downloading speeds?
Any help much appreciated!
-Ollie

I think you're making the same mistake a lot of people make.
The maximum download speed I have seen on my computer is 80kb/s
Safari reports downloads in kiloBYTES per second, not kilobits, so that 80KB/s translates to about 640 kilobits per second.
downloading the Adobe trials, when they reach about 1gb
Really? 1 gigabit per second? I assume that's a typo.
speedtest.net has told me that my download speed is 1mb/s
therefore your downloads are progressing at about 64% of maximum. That sounds about right - you won't get maximum throughput for every download - it will vary based on server location, network load and more.

I'm with Sky, and have had very slow broadband for a while now. Above are the statistics from the test socket. Sky seem to think there is a problem with the line. I've now plugged the router into the main socket.
Any help would be appreciated.
**EDIT** My phone line is with BT, my broadband is with Sky. The problem Sky says is with the phone line it seems.

Hi Joe,
Try sticking your telephone number into this line tester page and let us know if it finds a fault. If it comes back clear, you'll need to go back to Sky as there'll be no issues with your telephone line. If it comes back with a line fault, we can get it progressed towards a fix

E1200 router: very slow download speeds, ok uploady got

I recently set up a new E1200 router to replace my old one. We are having problems with very slow download speeds (often <0.10 Mbps) even while the upload speeds are OK (8-10 Mbps). Our previous download speed over wifi was 10-15 Mbps.
When I first set it up, the download speed was very poor on the initial computer. After fooling around, it was fine. I don't know what I did that made it speed up. However, my wife's computer has had very poor download speeds. After rebooting my computer, the download speed has also dropped bak to <0.10. I was able to stream Hulu on my Wii just fine an hour ago.
What could the problem be?

So we could have this isolated, check how much speed you’re getting straight to the modem so we’ll have some point of comparison that from your internet provider. If through the router, you have struggles with not getting an acceptable value for download speed especially if it only happens with the wireless connection, you can try these: change the wireless channel and the wireless security on the router. If on the router, you have the channel set to auto by default change it to (3,6,9,11), just have to play around with it. Moreover, for the wireless security, select WPA2 Personal. If that doesn’t make any difference, update the firmware of the router, reset and have it reconfigured.

Why i have very very slow downloading speed on wifi on iphone5

While on wifi I am experiencing very slow downloading speed on iPhone 5. My iPhone 5 is a brand new phone, I have to wait for hours to complete a running download of about 40mb or so. Please help me and tell me if there is any solution to that. On the same wifi network I have the new iPad and iPhone 4 and iPhone 4S, all are working perfectly getting perfect speed while downloading but I can't on iPhone 5.

What you did was fine. Leopard is a little different to 10.4.11, but:
Repairing permissions is an important part of regular maintenance, and should always be carried out both before and after any software installation or update.
Go to Disk Utility (this is in your Utilities Folder in your Application folder) and click on the icon of your hard disk (not the one with all the numbers).
In First Aid, click on Repair Permissions.
This only takes a minute or two.

If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.
Once that is complete reboot again from your usual start-up disk.

My Verizon iPhone 5 has very slow upload speeds that causes my apps to time out. Is anyone else experiencing this? It only happens on 4g.

Then Restore your iPhone Firmware with iTunes on computer. See if better. If not, talk to Verizon and see if they know of the problem and if there is a fix. If not, then make Genius reservation and take iPhone to Apple for resolution under Warranty.
