Very fast internet disconnects frequently

I have very fast internet here at my school, but there is only one problem: it disconnects very frequently for a few seconds.
I use a thunderbolt ethernet adapter to connect to the network, and I have also used wifi. The speeds are similar, and both have the same problem of disconnections. As far as I can tell it's just purely random. Sometimes I'll disconnect many times with intervals of no more than 10-20 seconds, others, no disconnections for hours on end. I asked some buddies of mine and non of them have the issue, even though one of the have the exact same Macbook as mine and has the same specs, and also uses a thunderbolt ethernet adapter. I have come to conclude that this has nothing to do with how many people are on the network at the time, because it has happened to me at times like 5-6AM and also have been stable at 7-10PM at times, when all the students are on... My question is, what is the cause of this, and is there a way that I can fix this? I'm using a Macbook Pro with Retina 15" that i bought in 2013. I heard it might have something to do with a DHCP lease? I follow some fixes like renewing the lease and stuff. Nothing has helped. Any response will by greatly appreciated. THank you.

Thank you Loner T.
I think I found the solution under different Topic. It was problem with bootcamp 5, I think.
Here is the solution for this problem for those experiencing this issue. I was getting crazy for months.
Look at explanation of Fahrwahr in the link below. My internet is going good now.

I have very fast internet but my mac pro is downloading very slow?Do I have to clean it or something?

How do I improve the download speed of my mac pro? I already have very fast internet and wondering if I should clean my system or what.I have never done anything like this so not sure what to do?

I have the same problem, I hope that someone from apple gets back to us on this. Has been going on way to long now. We are not the only ones, but Apple seems to be ignoring this issue. Just as you have a very fast internet connection, so do I, and my dad's is even faster, and still being told 3 hours for a 1.5 GB dowload. Should be done in 10-15 min max.

Firefox is taking way too long to load pages. I have a very fast internet connection but firefox takes forever to load websites. At first it worked fine and very fast but now very slow??

Hi there!
do you test other browsers?
i suggest to make a clean install of newer version of Firefox like v8.0.

Connection to iTunes incredibly slow on a very fast internet connection

My connection to iTunes is incredibly slow. I have tested my internet speed and it is 75Mbps/s. I am currently in Singapore but have a U.S. iTunes account. It takes about 3-4 hours before a standard def TV show is ready to watch on either my iMac, my Macbook pro, or my Apple TV. This never used to be a problem until a couple of months ago, and it is incredibly frustrating. I have both my iMac and my AppleTV connected via ethernet but the situation is even worse over wireless. Does anyone have any ideas? This is killing me!!!

Hello and welcome...
This may not seem relevant to iTunes but make sure there's enough free space on your Mac's startup disk.
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you always have a minimum of 15% free disk space.

New Mac Mini Wireless Internet - Slow, Disconnects frequently

Hi all,
I've been doing some research and have read related posts about this, but I thought I'd share my specific situation to see if I could have any light shed on it.
As a long-time happy Mac Mini user, I was excited when I picked up one of the new 2009 mac mini models and ditched my old G4 mini.
My wireless connection on the old mini was never very fast, and I was extremely pleased when I first started up the computer and my internet FLEW! I thought, 'Finally!! I have fast internet!'
It was as fast as it had ever been, just as if it were plugged directly into an ethernet cable.
Well, that lasted only a couple of days. For several months since then, I have frequently been having connection issues. It is consistently slower than it ever was during those first several days, and at times, it is continuously disconnecting and reconnecting.
Needless to say all of this is very frustrating. My connection is to a D-link wireless router with a standard WEP key.
I haven't changed any settings since the internet was blazing fast those first couple of days, and I'm using my Macbook wired to ethernet at the moment, and it is perfectly fine.
Thanks for any insight or to anyone for pointing me in the right direction on this.

Very close to the same thing happened to me:
-- I also stepped up from a G4 (iMac) to a 2009 Mini.
-- I also saw a big improvement in my wireless connection.
-- I also saw a big drop in speed, reliability, etc. (Software Update seems to hang, etc.).
-- I am also very frustrated.
Slight differences:
-- Drop in speed happened between the first and second time I booted up -- just a few hours!
-- I'm on an Airport Extreme network (old domed UFO-style base station)... WEP key, etc.
-- My iMac is still a-ok... just a few feet from the Mini, so I don't see how it could be a location-related problem.
Have tried usual tricks (rebooting computer and router, etc) and a couple of things found on similar threads. Not a bit of difference yet.
So advanced thanks for any forthcoming help from me, too...

Frequent internet disconnects for over a year

I have been suffering frequent disconnects from the internet for over a year. Each disconnect lasts for up to two minutes, rarely longer. Sometimes the disconnects have been as frequent as thirty or more times per hour. Sometimes I have no problems for many days.
I'm using HH5 and have Infinity 2 with a typical speed of circa 60mbps. Speed isn't an issue but the frequent disconnects are a pain. BT Broadband support have been unable to see the disconnects happening. As far as they are concerned, the line is fine.
If the disconnect happens when I'm using Google Chrome, I get a status message "Resolving Host" in the bottom left and, after a short delay, a screen appears saying "This webpage is not available. DNS Probe Finished. No Internet." Other devices, including BTTV, either give a message to the effect that there is no internet connection or just "hang". As far as I can tell, all devices, whether wired or wireless, 2.4GHz or 5GHz,, disconnect simultaneously.
I have tried disconnecting every device from the hub except the BTTV and the disconnects still happen.
BT have checked the line countless times, sent an engineer to my house, replaced my home hub three times, I have replaced all cables, replaced the phone/broadband socket, done countless resets etc all to no avail. The HH5 lights don't change colour when the internet connection drops.
After checking the BTCare Community Forums and discovering the event log in the HH5 I discovered that, when the disconnects occur, an "IN: BLOCK [16]..." message appears in the event log for the Firewall of the hub. At the end of this message I have copied a 12 hour firewall event log from today. Every "IN: BLOCK [16]..." event seems to coincide with an internet disconnect so that amounts to circa 40 disconnects in the past 12 hours.
What are these "IN: BLOCK [16]..." messages and why does my internet connection drop every time one of these messages appears? I checked the IP addresses for some of these "IN: BLOCK [16]..." messages. The first IP address in each message I checked was in China. The second IP address for each event I checked is BT in Boston, UK. My suspicion is that the BT server is logging me out every time one of these "IN: BLOCK [16]" events occurs. Logging back into the server then takes up to two minutes and, in the meantime, I have no internet connection.
BT Broadband support in India say that there is nothing they can do to address these internet dropout issues. They can only deal with line or hub faults. Their only suggestion was to disable the firewall on my HH5 but, given all these potential attacks from Chinese IP addresses, I refused to do this.
BTW, the HH5 IP address ending in 65 is my BTTV box.
I'd be grateful for any help and advice to resolve this issue. Here is the Firewall event log;

Ectophile - thank you for your reply. I tried the quiet line test and the line sounds good. There's no crackle or static. Just a very faint hiss if I turn the volume on my handset up full.
I've had three replacement hubs in the last year or so and they have made no difference to the frequency of the internet drop-outs.
The only fault that has been detected in all of this time was back in January when BTTV 2nd line support in the UK establish a link with my PC and monitored the connection. (They had a lot of difficulty establishing this connection and they were convinced I had no internet connection even though I did at that point). As a result of this monitoring and other testing, they diagnosed a very brief, intermittent drop out in the fibre-optic link between the surface box and the exchange. The 2nd line support engineer commented that this was a very strange fault because the fibre-optic connection normally either works or it doesn't.
He called out a BT engineer to investigate the fibre fault. This engineer told me that he had "reset" the fibre-optic link at the surface box. Having done this, he couldn't find a fault so visited my house, undertook line checks, replaced my HH4 with a HH5, checked out all wiring, tested the socket etc monitored for 20 minutes, couldn't find any further fault and left. The problems have continued however and BT India support just keep running their standard line tests and finding no fault.
I tried running a repeating ping test today using a tool called “WinPing”. I was using my BT email server for the ping test. The ping was set to 1 second intervals with the time-out set to a high level of 3000ms. I wasn’t using the internet at the time so I have no idea whether there is any correlation between the "timed-out" and/or slow response pings and the internet drop-outs that I have been suffering.
The eight and a half hour test gave an average ping time of 45ms but there was a lot of variability;
101 pings "timed-out" without a response (>3000ms).
6 pings were between 2000ms and 2999
23 pings were between >1500ms and 1999ms
87 pings were between 1000ms and 1499ms
139 pings were between 500ms and 999ms
66 pings were between 250ms and 499ms
428 pings were between 50ms and 249ms
680 pings were between 40ms and 49ms
12,296 pings were between 32ms and 39ms
There were no periods of more than a few seconds where WinPing couldn’t ping the server so this test doesn’t explain why I get the frequent drop-outs of up to 2 minutes unless perhaps the problem is caused by short drop-outs causing my connection to reset? The message I get on my Laptop / Google Chrome when the internet connection drops-out is a “Resolving Host” message at the bottom left and, after a short delay, a screen appears saying "This webpage is not available. DNS Probe Finished. No Internet." Other devices come back with various message to the effect that there is no internet connection, even though the HH5 light remains blue.
Do the ping test results indicate any particular issue or are these results normal?

WAG120N - Frequent Internet Disconnection Issue

I have bought a Linksys WAG120N few days back & after i got it , i also updated it to the newest firmware from the Linksys site.The Firmware version for my product is , 1.00.12 Annex A.
But i am getting a frequent internet disconnection after installing the Router/Modem.I am not a newbie in this.I have done my CCNP with full marks & currently working in IBM India & i have enough knowledge on how to configure Routers.
I have done the Flashing in the correct process & after Flashing , i did a 30-30-30 Reset as explained in this forum somewhere but the issue is still existing.
I am listing below what i have done so far. :-
1) After getting the Router , i have updated to the newest firmware & Hard-Resetted the Router as explained in this forum.
2) Then i configured the modem with the values from my ISP.I have done it both manually & also tried the Linksys Setup wizard that came on the CD with the Product and the SETUP WIZARD HAS MY ISP ON THE LIST as well.
3) I got the net connected after configuring but only for some time.After that , i am constantly getting disconnected from the Internet no matter what if i use the Wired or the Wireless devices to access the Internet.I tried setting the Router with both wireless Security enabled & disabled.No luck in either cases.Almost all of the time i get a disconnection when the DSL Link is Steady on the WAG120N.So, this should not be a Line problem.Also i can access the Net with my ISP provided Modem.No problems at all.
4) I tried uninstalling the Anti-Virus & the Internet Security program i use which is Symantec Norton Internet Security 2010.No luck.
5) I have Formatted & did a Clean Install of Windows 7 X64 & Windows XP SP3 & tried running the Router on a freshly installed operating system with no other software installed.I tried different Machines , Different Operating Systems , Different Lan Ports.No luck.
6) I deactivated Windows default Firewall & every Power Saving functions of my OS.No luck.
7) Linksys suggested me to visit the Service Center & get a replacement.I did visit the Linksys Authorized Service Center & got a new WAG120N & brought that to my home.I had to pay around 20 USD Taxi Fare as the Service Center is at the remotest part of my city.I wish if Linksys had a Pick-Up & Drop facility which nearly every big companies offer in my place.
8) The new WAG120N did not change anything.The disconnection issue is still existing.
9) There is absolutely NO problem in my ADSL line.I am using a 512kbps ADSL connection & when i use the CHEAPEST Wi-Fi ADSL Modem which has been given by my ISP , i can access Internet just fine , no problems at all either in Wired or the Wireless.So, in this case The Linksys ADSL Router is at fault.
10) I can see the ADSL line Stats with my 20 USD worth of Huawei ( ISP provided ) Modem but the 150 USD worth of Cisco/Linksys WAG120N does not support showing the ADSL Line stats ( or at least the Firmware doesn't support it ) which is unbelievable for a company of caliber like Cisco.
The two most important things every Modem at least should display are :-
1 ) SNR Margin
2 ) Attenuation
These two are absolutely a Must-Have features if you want to see how good your ADSL connection is & i am surprised to see that my cheapest ISP modem does have these but a Cisco product does not. !!!!!!!!
I have called the Linksys support again & they told me that they are Escalating my case to their 2nd Level.
I got a response from their Level 2 Support Person & he asked me to provide information about my case & i had sent him a reply 2 days ago but no reply from him.
And I am NOT the only person with this problem.I do not know Linksys knows this or not but there are several Linksys users who are using this model & are facing the exact same issues as me.
Here are some of them & they have been posted on this community itself :-
1) http://homecommunity.cisco.com/t5/Cable-and-DSL/Wag120n-problem/td-p/300397
2) http://homecommunity.cisco.com/t5/Cable-and-DSL/WAG120N-keeps-disconnected-from-internet/m-p/330870/...
Tell me Sir , what should i do ? Should i sell it & get another brand or Linksys is going to help me to resolve the problem ? I am extremely sorry to say that i feel regretted that i invested my hard earned money into this which just does not want to work at all.I am too much frustrated & not going to buy any Cisco product if my problem does not get solved because i can not bother the disconnection problem as i need to stay connected all the time for my job & also for my personal reasons.It is a shame that i had to pack my Linksys up on the shelves & have to use the cheapest quality Chinese ( No offense ) Modem because at least the connection does not drop here & I can use it for what it is meant to be.
I will be expecting a quick reply from you people & would also hope that you will be able to solve the problem.Also i think the problem is not the Router but the Firmware itself is faulty but i am not sure about that because this is my first Cisco product & frankly speaking I am very much disappointed with it.I would very much like to experience a Cisco product because i thought it is an World Class product in the business.So, please help me resolve this problem.Either Linksys should help me resolve the problem and get me an working product or i would want to get my money back.Thank You.
(Mod note: Edited for guideline compliance.)

Yes but I think Linksys should give me another one which is working right ? Why should i invest in another Router as i just bought it & its already too pricey here.
I need an ADSL Wi-Fi Modem Router & there is only three models avilable here.One is this one which i'm using , WAG120N & the other two are WAG160N & WAG320N & both of them costs more than triple than that of WAG120N.And no one is going to give me a replacement here.I can get the replacement but the same Router.I can not upgrade it without having to buy a whole new router which costs thrice than my current one.
So, i would be highly oblized if Linksys can give me a replacement because only they can replace it with another model but Linksys India customer Care is only suggesting me that they can issue a replacement for the same model & can not give any other model.
I sent my concern to the 2nd Level Technicians but have not received any reply.Feeling helpless at the moment.
My posts are edited & most important parts are being deleted.Please do not edit my post.All i am wanting to get a suggestion for my problem.I do not want to bother you with my problems but the communities are meant mainly for that purpose so that we can help & support each other.
Thank you.

I have very slow internet even though my provider says the speed is fast

I am experiencing very slow internet even though my provider says that my speed is fast. The uploading of a page takes long to complete

If Safari is getting very slow:
(Presumably you regularly empty your Safari cache by deleting the following file:
Home/Library/Caches/com.apple.Safari/cache.db
and clear your History)
Adding Open DNS codes to your Network Preferences, should give good results in terms of speed-up as well as added security, (including anti-phishing and redirects) (Full information about Open DNS is here: http://www.opendns.com/home/nobloat ) and further independent information can be read here:
http://reviews.cnet.com/8301-13727_7-57338784-263/free-dnscrypt-tool-enhances-ma c-web-security/?tag=mncol;txt
and here:
http://www.macworld.com/article/1146064/troubleshootdns.html?t=234
If you are using a single computer: Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu, and in the box marked 'DNS Servers' add the following two numbers:
208.67.222.222
208.67.220.220
(You can also enter them if you click on Advanced and then DNS)
Sometimes reversing the order of the DNS numbers can be beneficial in cases where there is a long delay before web pages start to load, and then suddenly load at normal speed:
http://support.apple.com/kb/TS2296
If your computer is part of a network:please refer to this page: http://www.opendns.com/start/best_practices/#your_network and follow the advice given.
If you use a Router, make sure it has the latest firmware installed.
One reason for a slowness in page loading may be the 'DNS Pre-fetching' feature of Safari 5.x as is described here:
http://support.apple.com/kb/TS3408?viewlocale=en_US
You can cancel DNS pre-fetching by going to Terminal and typing:
defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false
You have to restart Safari for it to take effect.
If Safari seems to hang for ages:
If you have a lot of tabs open and/or a lot of pages running Flash, Safari can sometimes 'hang', requiring a restart of Safari. This can often be inconvenient, and as it is rarely Safari itself that is hanging but merely one of its plug-ins, usually Flash, there is a way using Terminal to restart the plug-ins (without restarting Safari and losing your tabs) by quitting the WebPluginHost process:
Open the Terminal from the Utilities folder in /Applications and type
killall -9 WebKitPluginHost
Note that this command kills all Safari plug-ins, not just Flash. All plug-ins should start back up when you reload the page.
Then go back to Safari and refresh any pages that were using the Flash plug-in. This also fixes the Beachball of Death. Try this whenever Safari gets slow or freezes. The later versions of Flash 10.1 onwards appear to have improved the situation somewhat, but haven't completed eliminated it.
For this and other reasons Apple switched their websites to HTML5 in January 2011:

Very slow speed and frequent disconnection

I have been using BT broadband since 6/09/13 and my speed has been below par so far. I have only received 3mbit/s or less when my line is capable of 8mbit/s. Along with this, I disconnect frequently for seemingly no reason. When I contacted bt support, they assured me that the disconnections was the exchange testing out my connection during the 10 day training period, but even after that the issues persist.
From checking the homehub's event log, I found that this message was being given when the connection dropped: "20:55:08, 20 Sep.(404656.240000) PPP LCP Send Termination Request [User request]"
Does anybody know what this means?

I've been connected to the test socket for a couple of weeks, and I've found that it makes no difference.
I've noticed the downstream noise margin has been very high: "DSL noise margin: 5.90 dB upstream, 17.40 dB downstream". I think this is what BT has set for my line, from my previous ISPs I had a 6db noise margin and my line was fine.
1. Best Effort Test:
Download Speed : 0.82 Mbps
2. Upstream Test:
Upload Speed : 0.76 Mbps
However the speed tester was unable to find my ip profile.

My airplay mirroring won't work with my macbook air, eventhoug my internet connection is very fast. The image will appear after 5 seconds.

My airplay mirroring won't work with my macbook air, eventhoug my internet connection is very fast. The image will appear after 5 seconds.

Mirroring is done over the local network so internet speed isn't relevant.
I would check istumbler.net to see if there is any interference

When i Using 3G internet The battery is reducing very fast. maximum I can Use 2.30 Hours with internet using. Is this possible ?

When i Using 3G internet The battery is reducing very fast. maximum I can Use 2.30 Hours with internet using. Is this possible ?

How long are you using internet for? Are you using WiFi or mobile data? Are you watching video on websites? There are many variables that could explain a perfectly natural battery drain. As I said previously you should try recalibrating the battery. My phone used to drain by mid-afternoon with little to no use until I found out about recalibrating. Since then its been fine and its something I do at least once a month.

Very Strange Internet Problems

I own a MacBook Pro 15.4 Inch that I purchased about a year and a half ago. I recently upgraded to Leopard and have all the latest updates. I am from the US, and when I am home my internet works fine. However, I am on travel to Seoul, South Korea right now and am having a very strange internet problem.
As far as I can tell, the URLs that I type in to my browser are, sparodially, not translated correctly into the webpages that they are supposed to represent. This problem is probably effective 75% of the time, and the rest of the time my internet works roughly correctly. For instance, when I enter http://www.google.com, instead of being taken to the Google homepage, I am taking to the homepage of Jammin Beats DJ Service, an obscure website about a company in northern Pennsylvania. The actual URL of this website is http://www.jamminbeats.com, but when my internet is malfunctioning, 'jamminbeats' is for all intensive purposes replaced by 'google' (that is, it applies not only to the main page, but to sub pages, so "http://www.google.com/weddings" takes you to "http://www.jamminbeats.com/weddings" and etc). For most other webpages, one of two things happens. Either I am taken to the correct page but it is displayed without any images or frames (just the html text and links), or I am taken to a blank page with the header "Under Construction", which I assume is the default for a page that doesn't exist. This is why it seems as though the URLs are simply being interpretted erroneously.
This problem occurs when connecting both to the wireless and the wired internet at my hotel, and it occurs on both Safari and Firefox, so it is not a connection-specific or browser-specific problem. It may be a problem with the hotel's internet, and as of yet I have not had a chance to test the computer at another location. However, a colleague using an IBM computer has had no problems, and I am currently on a Samsung machine in the business center of the hotel and it is working correctly as well. I have searched extensively online for a similar problem but have come up empty handed, and more than anything, I am confused about what might be causing this problem. The strangest thing is that a fraction of the time, the internet functions normally, but it is usually roughly 15 minutes out of every hour, and eventually I am inevitably taken back to Jammin Beats.
I am a computer science graduate but I still have no idea what would cause this problem. At first I thought it might be a hacker, but if it is, he or she has been at it consistently for 3 days now, and only seems to be targeting my computer. Any ideas or solutions would be greatly appreciated, as I have been forced to resort to the hotel's business center for checking email, doing work, etc. Thanks in advance.

I did consider that, as I was in Beijing last week and there are a number of censored sites. However, in Korea I have had problems with very basic sites like facebook, wall street journal, google, yahoo, Korean google, my hotel's webpage, etc. Further, I have successfully gotten all of these sites to load seemingly at random, and can access them without problems on other computers. The only disconnect seems to be between my MBP and the internet, not between Korean internet and the web. I have toyed around with the network settings, and although sometimes after switching from "Automatic" to a fixed connection I get some sites to work, it usually only lasts a short time and eventually the same sites stop working. I reset my cache regularly to make sure I'm not getting sent to cached sites, but this also doesn't help. Further, my Apple Mail, Skype and AIM accounts jump between being connected and disconnected randomly as well. Again, this is isolated to my own computer, which is why I'm so confused.

My WRT54G v5 router loses internet connection frequently

My WRT54G v5 router loses internet connection frequently. Sometimes occurs when you enter a web or sometimes every few minutes, but without a pattern. I have W XP Pro with SP3 and I have a pc wired to the router and sometimes 2 notebook with Wi-Fi. What could be the problem?. Thank you very much.

I have upgraded the firmware to v 1.02.8 and reduced the MTU to 1350 but after a few minutes of doing that I had the same problem... The router reboots itself, again and again and again...
It's possible to run some diagnostic utility that somebody can check ??
It's possible it would be a router failure ??
I note that sometimes is ok and when Entering some web pages the router reboots itself and I loose my internet connection, but others, the router reboots for no apparent reason...
I dont know what to do...
