Extremely slow, high ping internet

I'm again having problems with my internet. I never, ever had problems with BT, but the past month it's been dire. Around a month ago for a few days my internet was really unstable, but it sorted itself out, now today my internet is worse again.
I log in today to find out that it's extremely slow to load pages up and when I check my ping it's in the thousands and won't go down.
Phoned up BT, no help there.
Can't do anything, my ping is way too high. :/
Any help ?
Solved!

Extremely slow, often down, internet. ALL DAY LONG.

I'm a software engineer and very familiar with wifi/router setups. I don't see any issues with my equipment at home, and have rebooted all the equipment and computers in my household. I have already sent a PM to Uverse Support and have not received any response. I live in Los Angeles, in the Glendale/Eagle Rock area. My internet has been extremely spotty, mostly very slow (when up at all), and generally awful all morning and continuing into this afternoon. I work from home and this issue is severely impacting my ability to work. As I write this, I'm attempting to download a file for work. It's downloading at < 20KB per second, and has already failed twice. This is a 45Mb line. I've been logged into servers for my work and am constantly getting disconnected. This isn't a minor issue. It's almost useless, and extremely frustrating as I can't get my job done. It's been difficult even getting to this site to send the PM and now this. Is there a PHONE NUMBER I can call? Maybe there's one listed somewhere on this site, but I'm having a hard time even loading pages to look around to find it. In addition, the Community forum keeps telling me it doesn't recognize my login id even though I have already had it reset my password once (which then logged me in a couple hours ago when I sent the PM, but now it won't let me login again). I am desperately trying to NOT reel off a string of expletives here because I know that won't accomplish anything, but my frustration level is through the roof on this as it has been ongoing since at least 7AM this morning (now 4PM).

Since it's a 589 RG, have you disabled IPv6? That cause reboots, disconnects and browsing problems on the 510/589 RGs.

My computer is running extremely slow, especially the internet. I don't know why, but I need it fixed. Help?

Okay, I have restarted and shut down my computer to help it act right. I have reset safari, deleted my history, everything and it is still running slow! I have full bars of the internet as well, so I don't understand why it is running so slow. Does anyone have any suggestions?

Go step by step and test.
1. Power cycle
     Power off the router. Unplug it from the wall. Wait a while.
     Plug it back to the wall. Power the router on. Wait until all the lights are lit properly.
     It will take a   while.
     Restart the computer.
     Start up in Safe Mode

Extremely slow download speeds and internet browsing on Macbook pro

I recently got a 13"" macbook pro. System config - Maverick OS/i7 dual core/8GB RAM/750 GB HDD, Almost 690GB of free space available. I am expriencing extremely slow download and internet browsing speed. I have to wait for almost 10-12 seconds for normal sites to download. The app updates and downloads are painstakingly slow.
The internet speeds are working perfectly fine on my Windows Laptop, and even on my mobile phones. So, the there's no issue of network. Also, I have cleared safari cache etc, just to be sure. But nothing's really helping.
Can any one help me here.
Thanks !
Chetan

Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If the answer is no, do that now and see whether there's any change.
Quit and relaunch the browser. Any change?
Log out and log back in. Any change?
Enable Private Browsing in the Safari menu. Any change?
Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
Again, if only Safari is involved, open the iCloud preference pane and uncheck the box marked Safari, if it's checked. Any change?
Are there any other devices on the same network that can browse the Web, and are they affected?
If you can test Safari on another network, is it the same there?
If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

Macbook Pro 2011 extremely slow wondering if hard drive failure

Hello, I want to start off by saying I'm not a huge computer guru, so that is why I'm coming here first. My Macbook Pro worked very well for a year, and then it has slowed down drastically. I've always been a windows user so mac is kind of foreign to me, but I'm trying to learn.
Some problems I've encountered are 1. Extremely slow running whether internet related, or just an application. I have checked the activity monitor and nothing is hogging up my memory. 2. Spinning wait cursor (rainbow circle) when I try to do ANYTHING. It takes minutes to start computer once it makes it to home screen. The circle just spins for a few minutes. Even just web surfing it's there. 3. Battery drains from 100% to less than 20% in 30 minutes, which again is annoying. 4. When battery drains the fan turns on and seems to drain battery even faster. 5. I get a lot of random errors forcing shut down of programs. I have ignored this problem for two years by not using my laptop or using it very minimally, but I am going to be needing a laptop again for school and not just my iPad and phone so I was planning on taking my macbook to genius bar, but wanted to check here first since Apple is an hour away. Plus I want to be able to use the piece of equipment that I spent a decent chunk of change on. I used time machine to back up everything today. I know its not a space issue as I have 300+ free GB on hard drive. I have tried to read through similar posts, but its overwhelming so I came here to post my own question.
I ran disc utility and there were some errors, which were able to be corrected after a couple tries. Computer still slow though when trying to do anything and running rainbow circle.
In recovery mode I reinstalled OSX
I was finally able to install updates after completing the above that were not able to be installed before.
I ran etre check, this is the report that came up:

Basically I'm wondering if anything sticks out in this report. I was thinking it could be a possible hard drive failure. I know my computer has been dropped on the floor at least a few times. Thoughts are appreciated. Thank you for your patience.

Eab, I feel your pain! I am replying simply to share my similar ongoing experience with my early 2011 17 inch MacBook Pro, running Mavericks with seeming ample hard drive space, [applications requiring less than 100GB, about 200GB data (total drive space of 500GB)] & 4GB RAM. (Disclaimer: I am not a wise or computer-savvy mac guru - simply a fellow traveler who has had a very similar set of problems - apps taking forever to load, rapid battery depletion & super overheated MacBook. While I am a Genius Bar groupie, getting to the Apple store is, for me, akin to an antarctic polar expedition (i.e. problematic). Having spent endless hours struggling with a similar issue, I offer you a synopsis of my struggle/experience.
STEPS TO DATE:
1.Installed several memory utility programs (Daisy Disk & MacCleanse) system
maintenance program to regularly and thoroughly empty application caches (Adobe apps & internet browsers being tremendous hogs), identify and remove language elements and other redundant space hogs, etc.   Result: Small, but real improvement when I forced myself to perform a "scan and delete" session every second major computer run (typically about 6-8 hours in length). However, this did nothing to help the problems regularly detected when I run the Disk Utility which almost invariably demonstrates disk permissions that need to be repaired and, with increasing frequency, has demonstrated actual disk errors that require restarting and walking through a disk repair protocol. I did bring it to the Genius Bar where they kindly reinstalled Mavericks which they could do in about an hour versus the several hours that doing this at home requires. This did identify that my RAM was, on fact, a limitation on the speed at which I could run certain apps.
2. My next move was to install an additional 4GB of RAM. I bought the new RAM on eBay for about $90 because, with 3 kids equipped with MacBooks & iPhones, I simply couldn't afford the official Apple RAM. I even installed it myself, with the help of a YouTube video. Result: Giant improvement in speed (starting up or switching apps. If I had realized how simple it turned out to be, I would have done it well over a year ago. Some minor improvement in the overheating problem, but persistent problems with disk permissions continually requiring repair and periodic disk repairs (using Disk Utility) required.
PLANNED FINAL INTERVENTION:
3. I am purchasing and installing a solid state drive (ssd) and simply chucking the original hard drive, after considerable discussion with my savvier mac friends. It has become clear to me that, sadly, every hard drive has a finite life affected by a variety of factors. I am, in fact, hard on my equipment - running multiple graphic apps simultaneously, transferring massive GBs of data between my laptop, time capsule and an array of hard drives. I will let you know how it goes, but can share that the decision to get a solid state drive followed many conversations with multiple Mac guru-types (in the hope of saving you similar painful tribulations). The cost varies according to the size of the drive, but $400-$500 would buy a reasonable starting size. I am waiting for Black Friday sales, myself. Amazon (where I will likely purchase the ssd) is already offering a number of pre-Black Friday deals. While I don't really feel like putting out that amount of cash, I reassure myself that a new drive will almost certainly solve the disk errors (with a solid state one offering more durability) & will help me prolong the life of my MacBook Pro by a couple of years hopefully. It beats buying a new Apple MacBook only three and a half years after investing close to $3k for this one!
I am certain that more experienced forum users could point you to software that could help defragment your drive or may be able to offer other solutions. I've simply had enough of struggling with burning thighs and head-banging behavior triggered by slow performance. I hope this is helpful to you in some small way. The war is not yet over, but I'm feeling good about the battle plan!

Airport Extreme Slow Ping (Internet) Response

I am having problems with my dual-band airport extreme. When connecting to the external internet, I'm seeing high ping responses (>500ms) after about 5-10 minutes of resetting (hard reset) the Extreme and initially seeing 15-30ms response times.
I've tried:
1. Moving the router physcially in the house (no improvement)
2. Trying different channels on both 2.5 and 5 (some, but inconsistent improvement)
3. Multiple hard resets and reconfiguring the Extreme
4. Reinstall the firmware (haven't tried going down in firmware)
5. There are no cordless phones in the house
6. Absolute speed to the internet is strong (above my provider's stated speed)
7. If I connect my Macbook pro directly to the cable router, everything (ping + speed) is great.
8. Seeing slow ping responses both on my MacBook Pro and a separate PC
Any suggestions on how to troubleshoot? Seems like it a problem with the wireless connection and/or interference.
thanks!
Dale

had a 5th gen Extreme that I bought with 7.5 and immediately upgraded to 7.6. Saw the exact issue you described. exchanged it for a 6th gen Extreme, and am experiencing the same behavior again... both with 7.5.2 and 7.6 firmware.
everything is hunky dory when plugged directly into my cable modem.
third time's a charm, hopefully.

Very Slow Internet + High Ping

I am on a Sager laptop running Windows 7 and using an Airport Extreme Base Station as my router. I don't know how the router is set up or even how to access the router from my computer. My roommate set up the internet before I moved in. I have already contacted my internet provider and they believe my slow service + extremely high pings when I try to play any online game are a result of my router.
I am just looking for a way to correct my issue. I would also like to know how I can even access my router from my computer. Thanks.

+Is there any way for the owner of the device to limit the amount of bandwidth I am receiving??+
No.
+but I really don't understand why my internet is so crummy.+
Interference from other wireless networks or cordless phones is usually the cause of issues like this. If you have a cordless phone there, turn it off for an hour or so to see if things improve. Unfortunately, there's not much you can do about a neighbor's cordless phone causing problems or another wireless network.
+If I could access the utility what would you suggest I check?+
You can access AirPort Utility by going to the Downloads link on the main forum page. But, you won't be able to access any of the settings on the AirPort Extreme unless you have the device password, which is different than the wireless password. The first thing to do is try different channel settings for the wireless to see if you can find some clear airspace.

Establish IP from DHCP but no Internet or Extremely Slow

Synopsis: Net Macmin, New Ethernet Cat 6 cable (approx. 90 ft), DSL Comtrend Router. IP Connects, slow to no internet.
Added a 90' cable and ends across store basement from front PC to router in rear of business. Standard non-crossover Cat 6 cable properly crimped. Get IP Address from DHCP on front MacMini but internet is extremely slow. I re-ran the cable away from parallel to power conduit, still extremely slow. The light on the port which this cable is plugged in flashes at high rate with no pause, unlike three other connected to router.
Front MacMini works fine over wifi, but retail software recommended ethernet connection to ensure reliability should interference occur over wifi. When I'm testing the Ethernet I do shut off the wifi and have, since started testing, changed the service order so wifi is second chosen to ensure tesitng with ethernet is accurate when wifi is on.
When you try to load a webpage (I used google) through safari it loads 25% of the load bar and stops until it times out a few second later. Used network utility to verify connection to goolge, it took a few seconds longer than wifi but was able to ping google. I don't own a ethernet tester and would rather not buy one for one project.
Based on the ability to connect with IP address tells me the cable is able to talk back and forth with the router, correct? I've read a lot about ethernet port issues, how common is this, what else could be causing the problem?

Thank you to whomever can help and everyone that lends feedback!

My plan is to bring my MBP to the shop later this week to test this out. I wanted to put this out there to see if any other troubleshooting ideas were brought up. Thanks for the input!

Extremely slow and high latency all day.

DSL is running extremely slow during peak hours from 12 afternoon to 12 midnight. Lower than 50% of rated speed and high latency
I have been frustrated with this DSL Service for months now. I am considering contacting BBB to file a complaint and I am tired of dealing with customer service giving me the run around. Internet is a monopoly in my area therefore verizon feels it doesn't have to do anything to keep its customers when they provide crappy service. I am on waitlist for another internet service provider and it is going to take almost a year because of how bad the internet options are in the area and demand for better options. I even had to pay over 100 dollars to get a truck roll come to my house to fix any issues within the house and the internet has not gotten better. Atleast I feel I should get a refund or something.
Here is my speedtest result just now. http://www.speedtest.net/my-result/2899553407
It has been even slower at other times. http://www.speedtest.net/my-result/2893509440
Modem is Westell 6100 or something.

The round-trip time (RTT) between your computer and our server is 580 ms, which is somewhat high. This may be due to a variety of factors, including distance between your computer and our server, a slow network link, or other network traffic.
We recorded a packet loss of 16%. This loss is very significant and will lead to serious performance problems. It could be due either to very high load on our servers due to a large number of visitors, or problems in your network. Of the packet loss, at least 14.0% of the packets appear to have been lost on the path from your computer to our servers.
TCP connection setup latency (?): 720ms –
The time it takes for your computer to set up a TCP connection with our server is 720 ms, which is quite high. This may be due to a variety of factors, including a significant distance between your computer and our server, a particularly slow or poor network link, or problems in your network.
Background measurement of network health (?): 3 transient outages, longest: 0.8 seconds –
During most of Netalyzr's execution, the client continuously measures the state of the network in the background, looking for short outages. During testing, the client observed 3 such outages. The longest outage lasted for 0.8 seconds. This suggests a general problem with the network where connectivity is intermittent. This loss might also cause some of Netalyzr's other tests to produce incorrect results.
Network bandwidth (?): Upload 700 Kbit/s, Download 2.3 Mbit/s +
Network buffer measurements (?): Uplink 5400 ms, Downlink 1200 ms –
We estimate your uplink as having 5400 ms of buffering. This is quite high, and you may experience substantial disruption to your network performance when performing interactive tasks such as web-surfing while simultaneously conducting large uploads. With such a buffer, real-time applications such as games or audio chat can work quite poorly when conducting large uploads at the same time.

Your ISP's DNS server returns IP addresses even for domain names which should not resolve. Instead of an error, the DNS server returns an address of 199.101.28.20, which resolves to search.dnsassist.verizon.net. You can inspect the resulting HTML content here.
There are several possible explanations for this behavior. The most likely cause is that the ISP is attempting to profit from customer's typos by presenting advertisements in response to bad requests, but it could also be due to an error or misconfiguration in the DNS server.
The big problem with this behavior is that it can potentially break any network application which relies on DNS properly returning an error when a name does not exist.
The following lists your DNS server's behavior in more detail.
Please help. I am so frustrated I literally have fights with my family over internet problems. I am right now looking for other options and even starting to think about paying over 100 a month for dedicated line or T1 if they can service my area.

Not a single response from Verizon on this? And after you posted the tests & information they will need? I think I may have to make a service choice soon. Its bad enough Verizon can't post a simple email address for our support, they have removed Usenet access, removed access to our websites (I use HTML so their sitebuilder is useless)... Sheeshe...

Extremely Slow Internet From Linksys WRTU54G-TM

Hi all,
I'm hoping someone can help me with this issue. I got the Linksys WRTU54G-TM for T-Mobile's @home service. According to the store employees, I should be able to just plug it in and it should work. I got it home, disconnected my old router (a Linksys WRT54G) and plugged it in. After a few minutes, the phone was up and working and sounds good; however, the internet coming off of the router is extremely slow (both wired and wirelessly). So slow that pages won't load. The title bar will tell you where you're trying to go; however the page will not load.
Before calling for help, I contacted my internet provider (Cox Cable in Phoenix) and verified that the network was working and that my modem (Terayon brand) was good. When I hook the modem directly to the computer I get my full connection (around 20 megs down). Then I called T-Mobile and was connected to Linksys since the router was connecting and providing phone service.
I spent an hour on the phone with Linksys. We flashed the firmware to the latest build, reset the modem to factory settings, reset the modem via the button on the back all the while power cycling the whole setup numerous times. The rep had me check some settings on my computer and I was able to ping from the cmd prompt. In the end, she felt that I received a bad router and said I should return it. She never mentioned cloning the MAC address; however, I saw that on the T-Mobile forums and tried it - no luck.
I took the router back to the T-Mobile store and the rep happily exchanged my router for a new one. I got it home, plugged it in and have the same problem. Phone works, internet doesn't pass through the router properly.
I went ahead and flashed the new router and reset it factory settings and that did not help (all the things I did with the Linksys rep with the first router). I'm going to be calling T-Mobile/Linksys again tomorrow but I wanted to see if there was anything anyone in these forums may know what I could try.
With the second router, I did try plugging it into my old router (modem - old router - new router), the phone worked and the internet worked (both wired and wireless); however, the internet is not as quick as going through one router and I do not want to have two routers set up.
Secondly, I looked at the configuration of my old one and set the new one to the same exact settings; however, one setting could not be matched. My old router is set to an operating mode of GATEWAY, the new one is set as ROUTER. The only options on the new one are router and bridge. Could this be the issue?
It was recommend on the T-Mobile forums to run a speed test and post the results, which I can do tonight after I get home from work.
I've searched these forums, Google, the T-Mobile forums, the Cox forums at dslreports.com, and tons of other places and cannot find an answer. Based on the size of Cox, it's hard to believe I'm the only one with this issue. Any help would be appreciated. I have until Sunday to return the router and cancel the service without any termination fees.

Try the following settings on the router...
Change the Wireless Channel to 11-2.462GHz under Wireless tab...Under Advance Wireless Settings,Change the Beacon Interval to 75,Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304.Under Security tab,uncheck the option "Block Anonymous Internet Requests "...Power Cycle the router and check..

Extremely slow internet using wifi.

Hi guys,
First post here so be gentle.
After a week or so of using Arch I started noticing some strange things happening so far:
- Pacman's package list downloading from the repos happens at regular speed (around 700Kb/s), then followed by a 30 secs lag between each package download, which starts at normal speed, but then come down to around 2Kb/s then I get an Address Record error, which terminates the download.
- first ping to google is fine, then any ping after either get a 'host unknown' error or ping takes around 9Kms.
- another strange behavior that happens when pinging is that the wireless connection start at a bit-rate of 1Mb/s (according to iwconfig), then every time I ping google the bit-rate jumps (1Mb/s -> 12Mb/s -> 24Mb/s -> 54Mb/s -> 81Mb/s).
- can't load any websites (google takes around 5min to load, most other sites I just get a timed out error)
So my config is as follows:
- Intel Centerino Ultimate-N 6300
- connected using NetworkManager (but while connected with wicd the problem still occurs).
- running gnome 3.
- the router is Edimax 6524n
So far, I've checked resovle.conf (which only states my router ip address, which is fine because it serves as my DNS server), my hosts file (which is configured according to the tutorial in ArchWiki) and I've disabled the ipv6 module.
I've asked in several forums so far but with not much success, so i'm really hoping someone can solve it for me.
Thanks in advance!
PS: in one of the forums i asked someone asked me to post the output of dmesg | grep -i iwlagn, so here it is:
pastebin.com/Pmhi6swv
PS2: This problem does not occur in any of the Windows machines that are connected to the wireless network nor does it happen when this exact machine runs Windows; so the problem is definitely in Linux

I'm kind of having a similar problem. Ever since upgrading to 2.6.39 my wifi is extremely slow. It connects in g mode according to iwconfig and other network analyzing programs. I have iwl3945. The problem is. First it connects to wifi network(which takes about 30secs to successfully complete a connection request) it works great and I'm measuring 25Mbit(which is my internet connection speed) on speedtest.net. But after some minutes my speed drops to around 100KB/s and has a slight fluctuation, not quite constant. Even the upload is bigger than the download speed. If I disconnect the wifi, reload the kernel module and reconnect, then it works again for 1-2 minutes at full speed, then the speed drops again.

Any suggestions, or ideas would be very helpful. Thank you.

High Packet Loss, High Ping and Slow Connection Ov...

Hi There,
I have been a customer with the BT unlimited broadband package for a little under two years and up until recently have had no real issues with the service. This was until around 3/4 weeks ago I noticed that the internet was very slow and certain online games or applications like Netflix would lose all of its quality or stop completely. At first I thought nothing of it and simply reset my BT Home hub router, and sure enough everything was back to normal. However after around 2-3 hours of moderate use (gaming online or watching Netflix) the problem surfaced again.
Now I am lucky if I can get the entire way through a 40 minute TV episode before the quality drops and/or the service requires buffering. I have already contacted BT via the helpline and the service lady ran through the obligatory steps (turn off, wait 5 minutes, reset the home hub etc.) but she failed to understand that although rebooting the home hub does alleviate the problem initially, the symptoms of a slow connection, high packet loss and high ping always return within an hour.
Four the last couple of weeks I have been trying to investigate the problem myself and I have done the following things:
Tested the line using the master socket (no difference)
Opened the ports on my firewall within the home hub (no difference)
Directly wired in the computer instead of relying on the wifi (no difference)
Tested for interference from neighbours wifi using inSSIDider office (it wasn’t, operating on different channels)
Switched every device that requires internet off apart from the PC (no difference)
So with all that in mind I am fairly confident that it is nothing within my house that has caused a significant reduction in internet quality.
Now I have tried my best to display the problem I am having by recording the connection quality for the last 24 hours. The table below represents the condition and quality of the connection after leaving it a period of time without resetting:

I have also checked if the bell wire was attached and it is not. My socket is of the new type with the inclusion of an inductor on the faceplate. My ADSL filters and modem cable already have the middle connecting pins removed so I don’t think it is a wiring problem, at least in my apartment anyway. I have also searched for problems with the exchange and they are showing green for my area. (Liverpool Central)
I have just rang the quiet line and I do not appear to have any noise on the line. However, all I have is a cordless phone and I know that is not ideal for determining noise due to the radio frequency interfering with the phone speaker.
Again thank you for you time on this issue.

Richard

Slow Speeds/High Ping During Evening

Just signed up for Comcast this week. Noticed bad lag while gaming and speed tests indicate slow download speeds (<10 Mbps when I should be getting 75 Mbps) and high ping (200-300ms). Checked everything hardware related on my end and couldn't find an issue. Finally, did some trace routing and discovered high ping on Comcast servers in San Jose and Great Oaks. See tracert results below. These issues seem to occur during the evenings (8pm to midnight PST), but the few checks I did during the day seemed fine. It may be related to streaming volume at night. In any event, it's ruining my internet experience. How can this be resolved? Tracing route to e10905.dspb.akamaiedge.net [23.211.8.171]

The same thing is happening for me. I live in Houston, Texas and my ping to a game called LoL was around 80 now its at 90. It's not a huge difference and I don't notice anything when gaming. I'm just curious as to why this has happened?

Extremely slow internet data downloading

I have 2 other older Macs connected to my LAN both of which access the internet at normal speed. My new Mac mini pings addresses at the same rate as the other Macs but data download speed is extremely slow. Has anybody had this problem?

Define extremely slow.
Start with the basics:
1. System Preferences -> Network -> Network Port Configurations.
Uncheck all the boxes except the method you use to connect to the network (airport checked if you are wireless, or Built-in ethernet if you are wired)
2. System Preferences - Network -> Airport (or Built-in Ethernet depending on step 1.) -> TCP/IP -> Configure IPv6
Change selection to OFF
Under DNS (Optional Box) you may wish to manually enter in the IP addresses of your Service Providers DNS servers.
3. Because you have older Macs with an older selection of LAN hardware to access the internet you may want to see what the speed and duplex settings are on your box (access switch, broadband router, hub) and match those settings on your Built-in Ethernet if you are using that instead of Airport.
4. If you are wired, switch cables with one of the older Macs.
That should be a start.
