Network speed 100Full resets to 100Half

Hello folks! I have a MBA manually connected to an Enterprise network at 100-full duplex. The user complained of long download/upload file transfer times to a network server. I found that the machine network settings reset to 100-half duplex. When I changed it back to Full, file transfer speed was greatly improved (worked normally).
Now the user has called and said after logging in this morning, his MBA is back to 100-half.
Two considerations: 1) he often unhooks his network cable (to attend various meetings) without logging out of his account. 2) he uses a third-party USB adapter (Belkin?) to be able to connect an external mouse and network cable to the one available USB port on the MBA.
I am recommending to him that he not use the third-party adapter - to just use the Apple-supplied USB-to-Ethernet connector, and to log out of his account before removing his network connection.
Am I on the right path here, or can you see any other potential problems/solutions?

Not exactly answering your question but it sounds like the network switch is forced to 100/full instead of auto/auto. Whenever that happens the client comes up with 100/half. Can you change the switch?

Network speed WAY down for internet - help??

I have 3 airport extreme's set up as a WDN. It all works great. Internet is fast through a cable modem attached to the main stations WAN port.
It seems though that when "certain" users are getting into heavy internet traffic, seemingly large continuous downloads, the REST of the network is slowing down. The internet slows down to a CRAWL, so much so that eventually safari brings up the "network troublshooting" thing.
What is perplexing about this is that when I try to remote desktop to another machine on the LAN, THIS TOO has slowed to a crawl! There are no other LAN transfers or interactions between machines going on, ONLY NAT/DHCP net access.
I KNOW it is other users, because when I disconnect the internet, the network speed instantly goes back to super fast, remote desktop works great etc, then it seems somebody is starting their download again (ha ha that I just disconnected) and suddenly it's crawling. This doesn't seem right, not with only 3 - 5 users on a 3 base station system, and a 1Mb/s internet cable connection.... does it? At least, if the internet is slowing down, other LAN traffic (non internet related) should not right?? This is the part that has got me confused.
Also is there any software out there that will let me see stats from the main station in regards to:
- DHCP LAN assignments
- and upload / download traffic of each of those LAN addresses and other information.
Thanks,
Miklos.
PS Just to be clear when the internet is extremely slow it is not one particular site - email doesn't work, and the same site, reloaded again and again does not load - the rest of the network is simultaneously slow - I disconnect the internet (log off via simple software app supplied by the ISP) and within 5 - 10 seconds, network speed is visibly up - things start loading properly, and the internet - the same site, starts to load very fast.
My dilemma is how can the internet usage slow the REST of the network, when it's a very fast system! Another point: I am NOT resetting the base stations, they are remaining online and nobody is getting bumped off, I'm only disconnecting the internet feed that's ALL, so it's not like they're getting kicked off and then network speed is resuming, they are still in effect logged on to the network, they just can't access the internet.

Did you run it in store? If so, the wireless instore is notoriously bogged down/slow with all the things connected to it.

How to test network speed

How do I test the speed of my network to determine if Time Capsule or my Internet provider is behind a real slowdown in my internet access. I ran the java test at DSLReports.com and got the following results:
Compared to the average of 971 tests from comcast.net: download is 98% worse, upload is 98% worse.
I'm unsure where to look or what to look for in trying to find a cause for the problem but wanted to at least try and make a stab at finding out before I called Comcast.

You could try connecting a computer directly to your broadband modem and run the test again. That would remove the Time Capsule from the configuration. You may need to reset the modem to convince it to connect to a "new" device.
Are you connecting to the Time Capsule via Ethernet or Wi-Fi? If by Wi-Fi, the quality of your Wi-Fi connection could have a big affect on the network speed. In that case, use the advice in the second message of this thread to investigate the signal and noise levels that your Mac sees:

Try this first - 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. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts Tap on the Account, then on the red button that says Remove Account.

Very slow network speed

Since I changed from Mac OS 9.2.2 to Mac OS X 10.3.9 on my dual 450 Power Mac i am having always the same problem. after some new starts my network speed becommes very slow. internet, printer connection and also when using personal file sharing. Folder of 22MB takes about 1 hour insted of 3 seconds to send from one mac to the other. I was trying on both HD´s and with only security update from CD before using Internet. I also have to repair volume permissions.tried reset of PRAM. tried it with both HD´s separately installed, sometimes it helped for short time. but unfortunately I always get the problem also when I am not using intenet connection after installing 10.3.9 on a completely empty HD (also tried to formate mith zeros). On my other mac´s: G3 (400MHz), G4 (500MHz) PowerBook and Power Mac G4 450(single)
the system is working without any problem. same settings! Only the Power Mac G4 dual 450 I am having this problem. Software like Photoshop, X-Press and also Maxxon 4D are running fast and without problems. Please help me!!!

HT1725 the network connection was reset. stopped err-3253

the network connection was reset. stopped err 3253

I tried EVERYTHING.
Eventually I installed a new modem/router and hey presto - problem solved. I think that the modem was on its way out as the new modem has increased access and download speeds significantly.

The Network connection was reset everytime on different networks.

Hello,
my problem has been exasperating as I have wanted to get my podcasts on to itunes for sometime. The first thing I did was suggested was run it through the feed validator that gave me the thumbs up and I thought everything would run smoothly. Sadly I have been getting a hard time going through the first phase.
Everytime I try to run my RSS feed through the submit podcast it works at it for a while and then comes up with the "We could not complete your iTunes Store request. The network connection was reset."
So at first I thought it was my computer and my home network. I disabled the firewalls and my anti-virus software and still received the same answer. I then checked my internet speed and the website gave that the double thumbs up as well.
Next I contacted one of my subscribers and asked if they could check out their feeds. Apparently my RSS feeds from my website work well and they are indeed alerted when we bring a new show out.
I also contacted my Website Host asking them about the status of the server and they said everything is going great. Next I asked a friend if he could try to submit the podcast through iTunes and he received the same thing.
I have spent many hundreds of hours producing radio drama in a podcast format but now I am able to go through any RSS feeder except itunes. What on earth can I do about it?

The feed looks OK and can be subscribed to manually in iTunes; so one of two things is happening.
1. We've seen instances where a feed which worked elsewhere wouldn't work with the Store itself (which is a different matter from the iTunes Application when you subscribe). This appears to mean that the server is not responding properly to requests from the Store, though I've never seen an explanation for this. Only the people running the server can sort that out, by looking at the logs. I don't know how likely it is that this is the explanation.
2. There may be a temporary problem with the submissions process: this is not unknown. You could try this alternative URL:
https://buy.itunes.apple.com/WebObjects/MZFinance.woa/wa/publishPodcast
but if that doesn't work you could leave it for a day or so and try again.

Hi, I am trying to update an iPhone 4 from iOS 4.3.3 to iOS 7.0.4, and every time I try to update it comes up with an error message saying that there was a problem because the network connection was reset. Is there any way I can get past this and update?

The full message said:
There was a problem downloading the software for the iPhone "Judy's iPhone 4". The network connection was reset.
Make sure your network settings are correct and your network connection is active, or try again later.
I am trying to update the iPhone for my grandmother, Judy, as I am leaving for Paris on Wednesday night and we want to have Facetime installed on her iPhone before then, so we can stay in contact with each other. It is the simplest way for this to happen but the program simply will not allow me to update her iPhone.
Is there any way to get past this error and update her iPhone? Any help will be greatly appreciated.

Dear Jody..jone5
Good for you that can't update your iphone because I did it and my iphone dosen't work for example I can't download any app like Wecaht or Twitter..
Goodluck

ITunes Store Error Message: "network connection was reset"

I've been having trouble connecting to the iTunes Store since Dec. 25, 2006. The last time I was able to connect to the site was Jan. 2, 2007!
The error message that I have been receiving is: "iTunes could not connect to the iTunes Store. The network connection was reset."
Here are the troubleshooting issues that I have already performed.
1) Ensured that my internet connection was active.
2) Checked to make sure Windows XP Service Pack Updates were compatible. No problems with the firewall detected.
3) Have the latest version (7.02.16) of iTunes.
4) iPod software is up to date.
5) Ran iTunes diagnostics which states:
Windows Firewall is on.
iTunes is enabled in Windows Firewall.
Connection attempt to Apple web site was unsuccessful.
The network connection was reset.
Connection attempt to iTunes Store was unsuccessful.
The network connection was reset.
Secure connection attempt to iTunes Store was successful.
Does anyone have this problem? Can anyone recommend a solution that worked for them?
Sony Windows XP

PS: I also went into Internet Explorer...
Selected Tools, selected Internet options, then selected Advanced Tab
Then I looked for the security section and made sure that SSL 2.0 was selected.
I was still unable to access iTunes Store.

When trying to log on to the iTunes store I get the message 'We could not complete your iTunes store request. The network connection was reset'.

When trying to log on to the iTunes store I get the message 'We could not complete your iTunes store request. The network connection was reset'. I can access my account on a different PC but not my own. Can you advise me as to what I should do please?

If Join was on then your home wi-fi must be set to Non-Broadcast. If you did not set this up (maybe your provider did) then you will need to find the Network Name they used, and any password they used. The SSID is Security Set ID and to see more try http://en.wikipedia.org/wiki/SSID . Basically it is the name used to identify your router/network. A lot of times the installer will leave it set as LinkSys, or Broadcom or whatever the manufacturer set it as for default. Your best bet is to get whoever installed it to walk you through how they set it up, giving you id's and passwords so you can get in. HOWEVER, if you are not comfortable with this (if you set security wrong, etc.) you would be well ahead of the game to hire a local computer tech (networking) to get this working for you. You can also contact the vendor of your router and get help (if it is still in warranty), or at least get copies of the manuals as pdf files. Sorry I can't give you more help, I hope this gives you an idea where to go from here to find more.

Network speed affected by large file copy operations. Also, why intermittent network outages?

Hi
I have a couple of issues on our company network.
The first is thate a single large file copy imapcts the entire network and dramatically reduces network speed and the second is that there are periodic outages where file open/close/save operations may appear to hang, and also where programs that rely on
network connectivity e.g. email, appear to hang. It is as though the PC loses it's connection to the network, but the status of the network icon does not change. For the second issue if we wait the program will respond but the wait period can be up to 1min.
The downside of this is that this affects Access databases on our server so that when an 'outage' occurs the Access client cannot recover and hangs permamnently.
We have a Windows Active Directory domain that comprises Windows 2003 R2 (soon to be decommissioned), Windows Server 2008 Standard and Windows Server 2012 R2 Standard domain controllers. There are two member servers: A file server running Windows 2008 Storage
Server and a remote access server (which also runs WSUS) running Windows Server 2012 Standard. The clients comprise about 35 Win7 PC's and 1 Vista PC.
When I copy or move a large file from the 2008 Storage Server to my Win7 client other staff experience massive slowdowns when accessing the network. Recently I was moving several files from the Storage Server to my local drive. The files comprised pairs
(e.g. folo76t5.pmm and folo76t5.pmi), one of which is less than 1MB and the other varies between 1.5 - 1.9GB. I was moving two files at a time so the total file size for each operation was just under 2GB.
While the file move operation was taking place a colleague was trying to open a 36k Excel file. After waiting 3mins he asked me for help. I did some tests and noticed that when I was not copying large files he could open the Excel file immediately. When
I started copying more data from the Storage Server to my local drive it took several minutes before his PC could open the Excel file.
I also noticed on my Win7 client that our email client (Pegasus Mail), which was the only application I had open at the time would hang when the move operation was started and it would take at least a minute for it to start responding.
Ordinarlily we work with many files
Anyone have any suggestions, please? This is something that is affecting all clients. I can't carry out file maintenance on large files during normal work hours if network speed is going to be so badly impacted.
I'm still working on the intermittent network outages (the second issue), but if anyone has any suggestions about what may be causing this I would be grateful if you could share them.
Thanks

What have you checked for resource usage during one of these copies of a large file?
At a minimum I would check Task Manager>Resource Monitor. In particular check the disk and network usage. Also, look at RAM and CPU while the copy is taking place.
What RAID level is there on the file server?
There are many possible areas that could be causing your problem(s). And it could be more than one thing. Start by checking these things. And go from there.
Hi, JohnB352
Thanks for the suggestions. I have monitored the server and can see that the memory is nearly maxed out with a lot of hard faults (varies between several hundred to several thousand), recorded during normal usage. The Disk and CPU seem normal.
I'm going to replace the RAM and double it up to 12GB.
Thanks! This may help with some other issues we are having. I'll post back after it has been done.
[Edit]
Forgot to mention: there are 6 drives in the server. 2 for the OS (Mirrored RAID 1) and 4 for the data (Striped RAID 5).

Poor network speed with 1st generation time capsule and multiple airport express 5Ghz. My network speed slows to a crawl when not close to the time capsule. I get the range that I need, but the speed is painfully slow.

Hello,
I have a first generation time capsule running 802.11n (b/g compatable) and the airport expresse's are the newer 5ghz models. I have 3 airport express's and I have the range that I need. I can run the time capsule using 802.11n 5ghz, but I loose the range and can't connect to all of the airport express's. My computers and mobile devices run 802.11n. Does anyone have any suggestions on how to increase the network speed. Would the new airport extreme fix the problem?
Thank you

Unfortunately, you are experiencing one of the downsides to 5 GHz. That's because the higher frequency 5 GHz signals are much weaker than 2.4 GHz signals.
After all, you always have to give up something to gain something else. In the case of 5 GHz, you gain potential speed but in return, you must give up penetration power and distance capability.
In order to work well, 5 GHz signals need to almost have a line-of-sight relationship between devices. Unless you can achieve this, you will do much better to leave the Time Capsule running at the 802.11n (b/g compatible) 2.4 GHz Radio Mode and allow the Express devices to "extend" that network.
As for the location of the AirPort Express devices in an exended network, that is critical for best performance. That's because the Express can only "extend" the quality and bandwidth of the signal that it receives. Post back if you need a few more tips on how to find the best location for the AirPort Express devices.
Would the new airport extreme fix the problem?
Unfortunately, no.

Cannot connect to the iTunes store. The network connection was reset.

My iTunes has been messed up since August 17th. I am getting the error message; "Cannot connect to the iTunes Store. The network connection was reset. Make sure your network connection is active and try again." I am having no issues connecting to the internet or even receiving my podcasts. It just won't download my TV shows or let me shop. I have contacted Hewlett Pack. about this and iTunes/apple. No one seems to have an answer for me. I have disabled my firewalls, norton, done msconfig, allowed iTunes, everything. I am very frustrated and so are others that seem to be having this same problem. We need a genius!! Please help!

I suspect a location-driven problem here. I live in SHanghai, China - as does the poster above! I have this problem on three different computers using three different ISPs.
Anybody got a suggestion? Tried firewalls, turning off virus production, reinstalling iTunes, putting phobos.apple.com and such in the permitted list, all sorts of stuff, to no avail. And Apple help support just bounces me around - I've interacted via email with three people, finally graduated to a real person, and they sent me back to email when the usual "reboot your machine and reinstall iTunes, then turn off virus protection" didn't work.
