Limit inernet connection speed

I'm trying to write an app that can limit the internet connection speed(network speed) of the PC. Thus all programs running on that PC should have limited internet speed (eg 200kbps).
Can anyone tell me how to do this?
Thanx

The thing is, that I have a server running, download and running updates the whole time. Now I want to write an app that can manualy limit/pause the internet via network from an other PC. Eg if I want to surf/browse the web on my pc, I want to limit the internet speed on the server, otherwise the connection is too slow.Naturally of course the only way that is going to happen is if something changes on the server or the network infrastructure. Thus how do you think that you would accomplish this using either the router and/or the server in the first place?

Basic connection speed questions for WRT54GS v.4

Hi, and sorry, I am something of a network numpty (though I understand my pc pretty well)
My router only ever transfers data at 54mbps (according to the wireless network connection icon in the system tray) - so, what has happened to the speed booster increasing it to 108mbps? Is 54mbps the best I can get?
Is this 54mbps in each direction = 108 total?!
And, how does this then limit my broadband downloading speeds? I have a 20Mb connection, and get around 17Mb speeds on my desktop pc which is connected via an ethernet cable to the router. The laptop, connected by wireless, gets 6Mb max - is this being limited by the router's capabilities?

First of all, Speedbooster is a software enhancement to the router. It does not change the basic wireless g connection speed of 54 Mbps. The Speedbooster enhancement is supposed to give you a 10 to 20% boost in data throughput. In order to get the full benefit, both the router and your wireless adapter must have Speedbooster. If only the router has it, you still get a benefit, but not as much.
Under ideal lab conditions (read: not in an ordinary home) a wireless g system can deliver as much as 20 to 25 Mbps of data. Most home users get substantially less. Most home users are happy if they can get 50% of their wired speed (in your case, 50% of the 17 Mbps). Some have achieved as much as 80% of their wired speed.
Its possible that 6 Mbps might be all that your system will be able to do, but I would suggest that you try a few adjustments and see if you can improve it. Here are my suggestions:
First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal, and this can give a slight performance gain.
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. In rare cases, Bluetooth devices can interfere. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna should be vertical.
Also, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. If your current network is not listed, enter its info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings".
If the above does not fix your problem, download and install the latest driver for your wireless card.
If you still have problems, try the following:
For wireless g routers, try setting the "Transmission Rate" to 54 Mbps. For wireless n routers, try setting the "n Transmission Rate" to 162 Mbps, and the (wireless g) "Transmission Rate" to 54 Mbps.
If you still have trouble, download and install the latest firmware for your router. After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you saved a router configuration file, DO NOT use it.
Hope this helps. Please let me know your results.

Ridiculous Connection Speeds

Hi All,
Following issues with line noise which have gone since removing the front plate from my OpenReach master socket and plugging directly in there, I now have an issue with really poor latency and speeds. I don't want to have to restart the HH3 as it's been up for over 3 days now (a record) which is strange as the HH3 shows uptime of 2days 4hrs - last IP change was 26/4 15:33.

Hi klinkenhoff,
Your IP Profile would be about 2mbps as it's 88.2% of your current connection speed which was 2.212 Mbps from your last set of adsl stats.
Your throughput speed is the speed you experience when using the Internet and is also the speed which speed test websites use.
Your throughput speed will be slightly slower than your IP Profile and can be effected by how you connect to your router/home hub such as Wifi or Ethernet and also network traffic and congestion.
So:
1) Your connection speed is the speed which your homehub/router and the local exchange is connected at.
2) Your IP Profile is a speed limit applied to your broadband service by the local exchange. Its purpose is to ensure the exchange doesn't 'overload' your broadband service by sending more data down your phone line than it (or your BT Home Hub, router or modem) can physically handle.
As your on ADSL2+ your IP Profile will always be 88.2% of your connection speed.
3) Your throughput speed is the speed you experience when using the Internet and is also the speed which speed test websites show, it can be effected by how you connect to your router/home hub such as Wifi or Ethernet and also network traffic and congestion
Hope that makes sense.
Cheers
I'm no expert, so please correct me if I'm wrong

Im getting slower Connection speeds

Im getting slower connection speeds then what i ordered i got the 15mps and i only get 10 ?

It looks like you're right at the edge of the 10Mbps service limit for your copper line, as your margins are low and the line speed is incorrect.
Do you have access to a NID? If so, can you plug your modem into your NID's test jack and pull up the new statistics it shows? The NID can often times be found outside on the side/rear of your home, near your electrical panel/meter or on a pole near the street (uncommon for the last one).

2 questions about connection speeds

Hello,
First up: I've been using the same ISP for 3 years now, at the same apartment, and my top download speed has always been 1.5Mbps (roughly 185K/s). For some reason my top download speed "now" is precisely 150K/s, and it's been that way for the past week or so. (And this speed limit affects all my internet-aware apps.)
Is it possible that I've set an OS-wide download limit without realizing it?
Second question: I'm using MenuMeters to determine my connection speed. When using Transmission, a Bit Torrent app, I can also read it's total downloading speed. When MenuMeters tells me that my total download speed is 150K/s, Transmission tells me that it's only downloading at 135K/s.
Trouble is that Transmission is the only app running. And indeed if I pause the downloads, MenuMeters indicates 0K/s (so there are no other internet-using apps running). Since I haven't found any report of speed errors on the Transmission forum, I don't understand this incoherence.
Any ideas?
Thanks
Loa

Hello,
Tom: very close to what MenuMeters was telling. So I guess Transmissions has some bugs.
But that doesn't solve my other problem: why isn't my top speed 185K/s anymore? Can this be on my side, or is it entirely up to my ISP?
Thanks
Loa

Very strange internet connection speed issue,

Good Evening all.
I have a strange issue. I got hooked up with a new ISP a few weeks ago and since that time I have had very slow PC connection speeds. I have done speed tests, and I get between 16 and 17mbps down, but the PC runs and acts like I am getting 4 to 5mbps. I have a Compaq Presario running Windows Vista Home Premium. Service Pack 2. There is 3 gig of ram and a 3ghz processor, with a 32 bit OS.
Here is how the setup looks. The netgear modem is plugged into a regular phone jack and then goes through a router and then it is hardwired to the PC. If I wire the PC direcly to the modem instead of going through the router, I get the same mbps no matter what. Between 16 and 17.
The wierd thing is that I can watch a movie on Netflix through my Wii with no issues. This is strange to me because I would figure there to be more issues with wireless connections rather than wired connections.
I have a netgear modem and a netgear router.
I am almost wondering if my PC is not processing the incoming speed correctly. I don't know if this is correct, because I used to have Xfinity internet before this new internet and had absolutely no problems. BTW my new ISP is called Edge Networks. The boast speeds up to 30mbps. I know that 16 to 17 is pretty good, I just do not know why It seems like I am not getting anywhere near that.
While on the subject, I also have another PC that I have gotten a USB adapter and am using wireless to access the internet. This PC gets 5 to 6mbps down. It is a Compaq running Windows 7 Home Premium Service Pack 1. It has 3 gig ram and a 64 bit OS with a 2.3ghz processor.
I do not have a clue why I have such slow inernet page loading speeds, other than the possibility that my PC's are just severly outdated.
Can anyone help explain this issue?

Evadfa, welcome to the forum.
I suggest contacting your ISP for help with the problem. They should be able to help you since they know their product better than anyone. I don't believe that it is a computer problem, since it is happening on two separate computers.

Connection Speed reading for external USB Modem ????

In previous versions of the Mac OS, I've been able to see a readout of my connection speed achieved with a dial-up modem and telephone line (e.g. 28 kbps, 33 kbps, 50 kbps etc etc) but under this latest 10.5 Version of OS X I can't see this speed in the networking software that controls my Apple USB modem.
Has this feature been dropped with 10.5 ?
If not, how do I see the speed. It would be very helpful to see it as I sometimes travel to some pretty remote areas where phone lines are poor - so if you know the actual connect speed you have a good idea of what sort of size of downloads to attempt and not to attempt while on-line.
I can see such parameters as my time connected and IP address assigned by the ISP, but no connect speed.

I realize the speed that used to be shown was the initial speed the two modems involved, mine and the ISP's, negotiated to establish the connection and I also realize that is not the actual download speed.
But it's still helpful to know that initial speed because it is a rough indicator of line quality ands gives one an idea of how rapidly he will be able to communicate - clearly there will be a significant difference for the better in performance for the online session if one can achieve a connect speed of, say 50k, as opposewd to 28k or less on a poorer line.

Issues with Infinity - Connection Speed & Other Pr...

Hi all,
I had Infinity installed on 2nd November. Besides some issues with BT mixing up delivery addresses the installation by Kelly Comms went smoothly, and was setup within 45 mins.
Initial speeds were very good, achieving 74Mb/s Down & 18Mb/s Up with a Ping/Latency of 5ms Excellent really considering the sub 5Mb/s I was used to with ADSL. The high connection speeds remained over the weekend until about 4pm on November 5th. I found that the Openreach Modem had lost connection (flashing DSL light) and my HH3 Broadband light was a steady orange. I left this for a while before picking up my landline to call customer services only to find that my line was dead with no dial tone.
Broadband eventually came back on service later that afternoon, but at a much lower speed of 43Mb/s Down, and an almost impossibly slow 0.97Mb/s Up. Ping/Latency has also slowed to around 20ms. During the evening I managed to get through to customer services in India, who were able to start dealing with the fault on my phone line.
Initially I was told it would be the 12th of November that the problem with the phone line would be resolved. Fortunately enough it was then fixed the following morning by an apparent engineer visit. I was unaware of this action until later in the day, but had noticed before leaving for work that Broadband was yet again down.
So to cut a long story short: I have a phone line that works, but a big reduction in connectivity speed especially upstream speed. Should I be contacting BT to investigate yet another potential problem bearing in mind that I am still within the supposed '10 day training' window.
(All speed tests have been conducted via a PC connected by ethernet directly to the HH3)
If anyone can advise me it would be much appreciated.

Hi Tidycarrot,
Welcome to the Forum. What was the speed estimate given to you when you signed up to the service? If the speeds you are see are well below that estimate, send me in your details using the link below and I'll run a few test on you line from here.

Problems with the Fios 20/5 connection speed in my area dropping down to less than 3mbs.

I have written out a flyer that I plan to go door to door with. Since I am under contract with Verizon, I am forced to honor my side of the contract. Even if they are allowed to make me pay for a service that I am not completely getting. I am very displeased and as soon as my contract is up, I will change back to My local cable companies all in one that does not require a contract and has no issue such as the one I am having.
Do you have Verizon Fios Internet?
Are you on the 20/5 connection?
If so, you may not be getting the speed you are paying for. I am on a 20/5 connection and when my computer is on for longer than an hour the internet download speed with Verizon Fios starts to slow down until it is below 3mbs. It takes about 24 hours to get down to 3mbs but only about an hour or two to get down to about 6-7mbs when I am paying for 20mbs…
I have 3 computers in my home that have Windows Vista, Windows XP home edition and Windows Media Edition 2005. All of the computers run into this same exact issue, I have tried every setting I could think of with my 24 years of computer technical experience. I finally took one machine with Windows XP and ran a full format on the hard drive and reinstalled a fresh Windows Xp Operating system onto the hard drive so it is a bare bones OS. This way there is no other software on the machine that could possibly be causing the problem and found that when I connected online through Verizon Fios the machine still ran into the same exact issue. This proves to me that the issue is not on any of my machines.
Now all of this time my buddy that lives 1.2 miles away from my house has been having the same issue with three computers at his home also. He has Windows Vista on two machines and Windows XP Pro on one.
When I concluded that it was a Verizon Fios issue, after a few months of trying to get by, researching, diagnosing and losing much information in order to verify it was on Verizon’s side, I contacted technical support at Verizon’s online website. The agent and I went through the regular procedure that anyone would have to go through and I patiently explained what I had done to try to diagnose the issue. The agent came to the conclusion that he could not figure out the problem so he guessed that the Verizon router/modem may be the issue and told me he would send me a new one by mail.
I received the new Verizon router/modem, installed it and had to call to have it activated. Afterward it still had the same exact issue as the prior router/modem. So now we know it’s not my computers, it’s not the router/modem. My Verizon router/modem is connected right at the Optical Network Terminal (ONT), which is the box that connects the fiber-optics to your home, usually just inside or outside your garage wall. Mine is just outside…
From here my buddy, who has been having this problem also the entire time, called the local office of Verizon Fios and an installer was setup to come over to his home and trouble shoot the issue. My buddy called me and told me when the installer was headed to his home and I met him at his home to see what the installer found and in hope that my issue would be fixed at the same time. The installer went through the system at his house and was frustrated about not finding the reason for the issue and ready to leave without fixing anything. I simply asked that he stay long enough to see the issue present itself within an hour-hour and a half.
His laptop itself already showed the speed drop from 20mbs to between 16-17mbs, it was on its way down. He basically told us something that online tech support already stated to me, it is extremely difficult to prove it is on Verizon’s side. In other words it is extremely difficult to prove it, in a way that will convince Verizon to check its own servers, routers and software updates to their own systems. The installer, good guy, couldn’t/wouldn’t stay but we did convince him not to simply drop the issue. He called shop and they sent another installer out to take over the issue.
The new installer, great guy, got up to speed on what was already done at my buddies home. The first installer, checked and replaced the Verizon router/modem, checked the wiring and splitters. Basically went through the entire system up to the Optical Network Terminal (ONT), the box that connects the fiber-optics to your home. He pulled and replaced the Optical Network Terminal (ONT), thinking that perhaps the unit was compromised. While he was doing this job a tech was called and asked to stop by for assistance with the issue. The tech checked the computers inside and tried to do some settings that the main office informed him to try. I explained to the tech that the same issue was happening at my house, that I went through every setting I could think of and find online to help alleviate the issue. After some shop talk about what I had tried, including the full format and reinstall of the operating system on one of my machines, he just as I came to the conclusion that it couldn’t be with the computers and since everything that had to do with the Verizon Fios system from the street to the end-user computer had been checked, verified and/or replaced, the issue had to be coming from Verizon’s main office.
The installer had already checked the main at the road that has the 3x2 green service cover on it by the side walk. Everything was in good working order. The tech called the main office to see if my buddy and I were on the same hub, basically a big splitter that continues the service from the main office to the homes, we were not. So that was ruled out…
My understanding of the system ends there. The only other components I know of are the Main branch’s routers, servers and software.
Verizon had a new connection speed added to their system, 25/15 about the same time our issue began. So I am guessing that when they updated the system to include this new connection speed they corrupted the software for the 20/5 connection.
We have been waiting to hear from the tech that was at my buddy’s house, to see if the issue will be dealt with. My buddy has called him a couple of times and he has mentioned that he is trying to get it addressed and to call back if we hadn’t heard from him. He remembered who he and I were and what the issue was, so I believe he is taking it seriously. How far he can move the issue is beyond me…
I want to add that my buddy and I have been customers with the all in one package from Verizon Fios since their services have moved into our area, about a year and a half… It has only been since about June that this issue has presented itself, before then we were on 7th heaven with the speeds. We couldn’t have been more than happy with the services.
This issue has caused that to all go afoul, not only do the speeds get down to less than 3mbs but the speed is not smooth at all. Rather the 3mbs speed is stop and go, freezing in between at times, very choppy. Barely usable at times, unless you restart the computers and start over.
We are hoping that anyone with Verizon Fios Internet Services will keep an eye on their speeds by going to http://speedtest.net and doing tests to verify they are getting the speeds they are paying Verizon for.
This is what it will take for Verizon to take this issue seriously is to gather everyone on the system that may be having the same issue. I believe it is everyone that is within the 1.2 miles from my house to my buddy’s and will distribute flyers to each and every house in between.
If you find that your speed is not as fast as it should be please contact me and I will add you to the list, this way we can see exactly how far this problem covers and perhaps it will also help to show a pattern and understanding as to why the issue is present in the first place.
My contact information,
I have left this out here, you can contact me on these forums...

Actually what this came down to was an issue between Windows Vista and an Ethernet Card on one of the machines in each of our local networks.
Even though our two machines are 6 years apart, we both have the same ethernet adapter on our main desktops. A RealTek RTL8139/810x Family Fast Ethernet Nic. It seems that the adapter does not work at the 20mbs download speeds with Vista. For some reason the adapter does not shut down when the computer does? I don't understand why but it doesn't, it keeps the connection alive. I removed the ethernet cable and pulled the power cable and had my two other computers still connected to the network and found that the issue was resolved. The way I found out was that I used the connections on my main computer to hook up one I had laying around and through further testing found the problem no longer existed...
Then I realized that my buddy and I installed Windows Vista at about the same time, a couple of months ago. Funny how you can forget an important detail like that. Then I remembered that he had the same identical ethernet adapter as I did, I had noticed that while trouble shooting his computer at his home but didn't think it was important at the time. Until the issue was narrowed down to the adapter, then it all seemed to all fall into line.
Quite humbling... In the end, anyone who has Windows Vista and this NIC probably will have problems with the 20mbs download speed of the computers on their own networks. I tried the latest Vista driver from RealTek and also tried to roll back the driver, with no success....
Back at the beginning when we first had fios installed in our homes there wasn't an issue when we had the 10/2 speeds and had Vista. Then we decided to change from Vista to XP because we both were having issues as to what programs you could use and which you could not, shortly after having fios installed. Then when verizon upgraded us to 20/5 we were amazed at the speed and still had no issue because we had XP on our main computers with the RealTek adapters...
We reinstalled Vista because it seemed like we were having more issues with XP by getting hit with Antivirus2008 and its variants and thought it time for a change back...
It didn't really hit us that Vista could be the culprit because we both have a laptop in our networks that have had Vista on them from the get go when there were no issues... We also didn't notice just how bad it was right away and over time kind of left the Vista install out of the equation.
Just strange that one computer can effect all the other computers on the network, even when it is shut down...
I allowed the other two computers to run 24hours and the issue did not present itself, when I added the main computer with the RealTek adapter back to the mix it reappeared. The Realtek adapter is the only real common denominator between his machine and mine.
So now we have three choices,
We can go back to Windows XP.
We can buy a new NIC or a wireless card to replace the RealTek...
Hopefully this post will help anyone else who runs into this problem, it has been very frustrating to say the least...
Thanks to everyone for their help and I apologize for complaining about verizon when it was not a verizon issue. I came to the conclusion that the only part verizon really played was upgrading us to a 20/5 tier which I am thankful for...
Would be nice if this card was on a list that Verizon support could use to troubleshoot , diagnose or eliminate for future support issues.

Slow Internet Connection Speeds caused by Ethernet Controller Driver

Problem: Internet connection speeds are 1/10 of available connection speed.
1. Problem statement is based on running speed tests at cnet, speedtest.net, and AT&T.
2. I am paying for 12 MBps down load speed but I only get about 1.5 MBps.
3. Other computers in household get 11+ MBps connected to the same ethernet cable and also different ethernet cables.
4. I traced the problem to the network controller driver.
5. I updated to the latest driver with no change in performance.
6. After some experimenting I found that if I re-install the driver after the computer is booted up, the internet connection down load speeds increase to 11+ MBpS (typically around 11.4 with maximum capability of 12)
I have assumed that the driver does not load properly the first time, but why? Or is there some other cause or setting that I have overlooked?

My Lacie Big Extreme Hard drive does not show connection speed

*My Concern*
Hi I have a Lacie Big Extreme Hard drive, which although works fine is not showing its connection, shows up in the system profiler as 'Connection Speed Unknown'. -Should I be worried? I have other drives connected to my G5 Dual 2 gig machine and no problem their they all show their connection speeds.
*Other Firewire 'Unknown Speed connection' related Problem*
I had a DVD LaCie Dual layer portable Firewire drive which recently suffered from the same problem and I had to send it back. This was due to it slowly developing a fault of not being able to burn dual layer disks properly.
*What I have done to try and remedy the situation.*
I have been able to do the following but I am afraid with no change in the system Profiler;-
1 Trashed the whole system and rebuild
2 repair my permissions
3 empty out all my caches with OnyX (third party app) version 1.8.5
4 Disconnected all drives and reconnected them one by one to see if there are any anomalies within the system
5 switched my G5 off removed the plug from the wall waited 30 sec for it to reset itself this was the 1st attempt. On my 2nd attempt I then cold booted the machine and reset Pram settings
6 used Tech Tools Pro 4 version 4.1.2
7. Replaced Power supply of the offending unit (didn't have to but I wanted to be safe and eliminate this fronm the equation.
9.tried changing around the order in the chain to which the drives were connected to the G5but alas no joy!
Summery
So my concern is if a device which is Firewire shows up in the system profiler as connection speed unknown should I begin to worry even though it appears to be functioning.
Thank you ahead of time for any help on this matter
*Supporting evidence*
Please see below a shot of my System profiler so you can see what I mean:-
*(Important Note)*
The Lacie Big disk has 800/400 Firewire connection speeds I have connected it straight to my G5s firewire 800 port then daisy chained the LaCie's via its other 800 port to the two other 800 Firewire Hard drives.
When the LaCie DVD DL drive was connected, I connected it straight to the 400 firewire port. As it needed direct access to the G5 for it to function optimally.

Hi BDAqua - thanks a lot for replying - really appreciate your help. I was using Time machine to back up on the old lacie drives that I have - I just backed up on both lacies and they backed up faster for some reason but that might have been because they were very small back ups as I did full back ups on Tuesday night - this is the info under the USB section > hardware > about my mac - it didn't show the speed like the example you gave me though but it still backed none the less :

I also got a reply back from WD on the hard drive and they said the following - exactly the same as you about it being a problem with the power supplied hence why the disk won't mount - so you were spot on - so I'm thinking I should go ahead and get the newertech 7 USB port 4 amps as you suggested - let me know what you think and then I'll just order it - and thank you - really do appreciate your help on this - thanks Jayas
Dear Jayas
Thank you for contacting Western Digital Customer Service and Support. My name is James.
If the drive is working fine on one system but failing on another especially with the "clicking" sound this is an issue with the system not being able to supply enough power to power the device.
These devices require power from the machine to make them operate if there isn't enough power supplied the drive will fail to work. This is why you are having no issues with one system but are on another.

Connection speed high but pages have been loading slowly for last 4 days.

My Broadband has performed well for the last two years but 4 days ago web pages have suddenly begun to take ages to load (10 to 15 seconds or more).
Checking my connection speed gives, typically, 7816 kbits downloaded in 1.542 sec.
The problem persists with Safari, Internet Express, Camino and Firefox.
Another problem cropped up at the same time in that a web site I use regularly suddenly became unavailable to me - but still OK for others. This also applied to Google UK until yesterday but now that is back.
Can anyone help?
Regards
Chris

IWeb publishing to .Mac/iDisk- interruptions: does connection speed matter?

Greetings,
I posted an earlier message somewhere in the iWeb08 forum regarding my suddenly experiencing lack of completion of publishing iWeb site to .Mac. Publishing just stops - no error message comes up. I have however noticed that my internet connection has been also varying in speed - down to a few dozen kbps in the last day, which is when I started experiencing this problem. Does connection speed affect such publishing? in other words, if connection speed goes down tremendously, does publishing to .Mac sort os "times out"???
Will appreciate input!

More than likely you are seeing a cached copy of your website. Sometimes this is a local phenomenon and a simple clearing of your browser cache does the trick (Safari>Empty Cache). However sometimes your ISP is the culprit with caching at their level. This seems to be a chronic problem with ISPs in the UK for some reason. And the only thing you can do is to wait it out.
You can try adding a "?" to the end of your URL to force Safari to fetch a non-locally-cached copy of your site, but even this won't help if your ISP is overzealously caching material.
Anyone in the UK can shed light on this ISP phenomenon???

Minimum Connection Speed & A few other Questions.

Living in rural Vermont this is of concern, is there a minimum connection speed for the CC versions?
If one has no internet access during the 23-33rd days but returns on day 35 what happens?
Can the check-in occur on Day 21 instead?
Finally, I saw mention made of CS7 and CS8. Are these in the planning stage? If the CC versions are simply a conveince for those who want this service and the regular updates are coming I would be very much happier.
Thanks!

Hi there,
There is no minimum connect speed requirement for the Creative Cloud membership or using CC products.
The two things for which you would need an Internet connection are -
1. downloading the creative cloud products that you would like to install & use
2. licensing & activating the products by signing in with your CC membership ID
for #1, Adobe has implemented a lot of improvements to be able to resume downloads of CC products post a network failure or outage.
for #2, a minimal Internet bandwidth is required
So, as long as your connection allows you to accomplish the above, you are all good.
>> If one has no internet access during the 23-33rd days but returns on day 35 what happens? Can the check-in occur on Day 21 instead?
If your CC membership is active, you will be able to resume working on the software after hitting 'Try Again' in the 'Renew your subscription' prompt that you will see in the software on the 35th day. We are working on certain enhancements that will provide flexibility vs. the monthly subscription check-ins.
>> Finally, I saw mention made of CS7 and CS8. Are these in the planning stage? If the CC versions are simply a conveince for those who want this service and the regular updates are coming I would be very much happier.
Please refer the letter from the Creative Cloud team for details - http://www.adobe.com/cc/letter.html

Very low connection speed.

Hi, I've waited the 10 days since I first got BT Broadband and I wondered about the slow speed I am getting. The speed test says my line is rated for 8mbit (8000kbit) but I only get up to 900kbit connection speed, it was around 600-700kbit for a while but now seems to have settled at 900~kbit. When I ordered the package the line check said I can get between 8 and 15megabit but should expect 8.5.
Is there a fault on the line? The online speed checker thing (which seems to have been replaced or I just can't find it anymore) said I should report a fault and that on my line I should be connecting at more like 6000kbit-7000kbit.
This is what my router says in the advanced connection page:
