Slow Internet Speed on Linksys router

I have an ibook that I use for work and when I am at work the inter speed is just fine (we're on an Airport). When I take it home and try to get on the net it is very slow. The crazy thing is, we have an Imac at home and connect via wreless to it and have no problems what so ever. Have any suggestions?

Mass market routers like Linksys are not very efficient with high speed broadband. I really don't think there's much you can do to improve the Linksys performance.
Just to be sure its the router you might want to check your cable modem signal strength; and the connectors from the street to your cable modem. Sometimes a bad splitter can cause very bad signal strength. You might want to test your speed by hooking up your iBook directly to the cable modem without a router. Run a speed test from somewhere like http://speakeasy.net. Be sure to pick a test location close to your home. If you get really fast speeds without the router than with the router then you know its the Linksys.
I had similar problems with Linksys. I upgraded it with the dd-wrt firmware. This improved reliability but not performance. You might want to buy a ZyXEL router which is very fast and very efficient. Also, its much more reliable than your Linksys router.

  • Help! Extremely slow Internet speed using Linksys WRT54G router

    I have an eMac running OS 10.3.9 and wired to a Linksys WRT54G router using ethernet cable. I have to use this router for my work PC. I'm also using WildBlue satellite internet. The problem is, I'm getting about 1.5 Mbps on my PC, but less than 33 Kbps on my eMac. It was running faster before using dial-up. I've called WildBlue and Linksys tech support, and they can't help. Can anyone help?
    By the way, my son is using his iBook on the same router, only wireless, and he's happy with the speed he's getting compared to dial-up.
    Thanks,
    Eric

    1400 kbps is a lot nicer than 33 kbps, isn't it? You can possiblly tweak it a little more --- I know I've seen a MTU of 1460 mentioned --- since you can also revert back to the 1400 MTU setting you found.
    (Broadband Optimizer is in one sense a nice GUI to the terminal commnads you found and used.)
    One more thing to be aware of, satellite internet is subject to longer latency times than cable or DSL, due to the unavoidable geometry of bouncing data packets off a satellite in orbit. That could be an issue if you ever want to play real-time online multiplayer adventure type games. It shouldn't be an issue for being able to grab OS updates in minutes instead of hours, through. Enjoy your broadband access!

  • Slow internet speeds and dropping connection

    hello, I am making this post on behalf of my dad, for a good few months (5-6 maybe even longer) we have been experiencing slow internet speeds and a dropping connection when ever the phone is picked up. when an incoming call is answered some or all devices connected to the internet drop out for a second then come back online, the connection does not completly disapear but causes any voice chat, streaming or gaming to disconect. We have BT wireless phones (not sure what exact type) which we have had for a few years. they are connected through an ADSL filter which as far i can remember has been there for years. We have a netgear DG834GT router which has also been there for a few years. I went onto its settings and got this information, not sure if its usefull or not.

  • Slow internet speed -upgraded it to highest speed

    I have had FiOS internet for about four years and never questioned the speed 10/2, but I had it plugged into the router.  On 3/4, I upgraded to TV FiOS/internet and phone bundle.  I do not have my computer where the router is located now (downstairs) and I had asked them to move it upstairs, but left before they had done it.  When I checked the speed (I guess the wireless speed since it is not plugged in to the router), it was 15.66/10 mbps.  I ordered the 35/35 mbps speed bundle.  I called Verizon and asked them about it and she checked the speed and said that it was "pretty good" considering it is wireless.  What?  I am not getting what I am paying for.  Do I need a DSL filter on all the phone lines?  Do I need a new router (I still have the old one)?  I have read on the community here that everyone has called several times to get an answer to the slow internet speed problem. Does anyone have the 35/35 mbps speed plan and have it work at this speed? I might as well go down to the 15 or 25 plan if that speed is all I am every going to get......But maybe if I go down to 25 plan, I'll get 10 or 15...... I will continue to try and work with Verizon to get this solved.   .Thanks for any help.

  • Slow internet speed - terrible service

    For the last 5 weeks I have been plagued with very slow internet speed. I have spent at least 4 hours on the phone with verizon techs. They always say that they will call back and never do. This is absolutely the worst service imaginable.

    Step one: Visit http://www.giganews.com/line_info.html and post up the Traceroute the page shows, if you wish. Be aware that your non-bogan public IP Address will show up.  It might shown up as the final hop (bottom-most line of the trace)  might contain a hop with your IP address in it. Either remove that line or show only the first two octets. What I'm looking for is a line that mentions "ERX" in it's name towards the end. If for some reason the trace does not complete (two lines full of Stars), keep the trace route intact.
    For example this what I saw when I was using Verizon
    news.giganews.com
        traceroute to 71.242.*.* (71.242.*.*), 30 hops max, 60 byte packets

    Step two: Can you provide the Transceiver Statistics from your modem?

  • Slow internet speed, being used by unknown websites

    Hello all,
    For about a month i have been experiencing slower internet speeds than usual. Contacted the isp and went through all the processes and there was not a problem at their end. I was advised to go to network utility and check how many processes there were, found out that there was too many to count.
    It seems i have internet processes coming from my macbook ip address from uknown sources such as ookla.com etc. Now i have downloaded spyware programs for mac which have failed to find any viruses or spyware at all.
    Now i know the problem is coming from my macbook as the unwanted guests our appearing under the macbook ip address, my router is receiving the right speed so it can't be the isp?
    Right now i am just wondering what to do to stop these processes using up my internet connection and potentially turning my router into a server.
    Any help would be grateful.
    Mark Lees

    Yeah i have little snitch but it appears to not spot these websites, i can send you a screenie of the netstat screen
    Then that would imply the only connections going out from your mac are from legitimate applications.
    lots of things will engage outbound connections.
    safari
    firefox
    itunes
    spotify
    and sites that you visit that have embedded video often host the video on other servers. So you would be suprised at how many socket connections you have at anyone time.
    If you have little snitch look at the monitor window and it will show all the recent connections.
    You could reset little snitch to default rules and then you will be prompted to allow or deny each new connection.

  • Internet speed impacted when router connected

    I have been keeping a constant check on our internet speed, primarily because our Bell Sympatico service peaks and troughs .. my speed without the router is 5600kbps .. when I connect the router however my speed drops to 2,200 .. why is that .... and can it be fixed .. because before I switched to this router, I had a d-link which recorded the same speed with or without the router connected.
    I've been giving Bell grief and have a service ticket out, which I may not need it seem to be the router ?
    Router is the WRT320N
    Message Edited by steelefamily on 10-06-2009 06:12 AM

    1)  When you said your speed drops to 2200 kbps, I assume you mean your speed when your computer is wired to the router  -- is that correct?
    2)  And I assume by "kbps", you do mean "kilobits per second", not "kilobytes per second"  --  is that correct?
    3)  If the answer to both 1 and 2 is yes, then the first thing to do is simply reset the router to factory defaults, then setup the router again from scratch.  If you saved a router configuration file, DO NOT use it.
    4)  There are several other things that can give you slow speed when wired to the router including:
    a)  using point-to-point (P2P) software.  This is a known cause for router slow downs and disconnections.  It can cause problems for several days after use.  Stop the P2P.
    b)  unnecessarily adding a "Domain name" to your router.  If your ISP does not require a domain name, erase the domain name from your router.
    c)  turning on "logging" in the router.  Logging is only for diagnostic purposes, otherwise, turn logging off.
    d)  Sometimes Linksys routers seem to have trouble synching to some very old modems.  The solution is to get a new modem.
    e)  Some computers will slow if you are using a wired and a wireless connection at the same time.  Turn off your wireless adapter.
    f)   Improper setup of modem and/or router  ---  to fix this, we will need more info:
    5)  Please state your ISP
    6)  Please state the make and exact model number of your modem (not the WRT320N).
    7)  Please do the following test:
    Power down your entire network.  Using an ethernet cable, connect your modem directly to your computer.  (Do not use the WRT320N for this test.)  Power up the modem and computer.  Verify that you have a working Internet connection, then proceed with the following:  (Even if your Internet connection does not work, state this, and proceed.)
    Go to "Start" > All Programs > Accessories > Command Prompt.
    A black DOS box will appear. Type in "ipconfig /all" (with no quotes), then hit the Enter key.   Copy all the results to your next post.  To do the copy, highlight the results, then use the copy (Ctrl-c) keys and the paste (Ctrl-v) keys.  If your "IP address" does not start with 192.168 , then for security reasons, erase the last half of your IP address.

  • Windows 7 64 Bit Very VERY slow internet speed

    I just bought two new laptops for my wife and I and we've been having terrible trouble with download speeds since taking them out the box. 
    We are using the exact same configuration and IP as before only our last two computers were on XP and Vista but there were no issues whatsoever. I even went and bought a new router just in case that was the problem but it made absolutely no difference, leaving
    me with the conclusion its a problem with the 64 bit version of Windows 7.
    Currently I cannot even watch a Youtube video because after loading the first couple of seconds, it stops loading and then after a couple of minutes there's a quick burst of speed and stops again.
    I can't complete a speed test on my connection on either laptop. Normally this would take only a few seconds but the site (speedtest.net) crashes every time using windows 7.
    Setup;
    Windows 7 64Bit
    Intel i3 2310M @ 2.1Ghz
    4Gb of RAM
    My IP is VirginMedia UK on a 10Mb connection (same problem wired or wireless)
    As you can imagine this is very frustrating since I have just paid out over £1000 to find my browsing experience has virtually at a stand still.
    Any help in this matter would be very much appreciated

    I recently had the same problem after installing Windows 7 64bit.  The internet speed for some reason was really slow.  After looking for a solution I tried to flush the DNS.  It worked.
    Open start menu
    type "cmd" in the search then hit enter key
    when the new screen opens type:
    ipconfig /release
     hit enter and then type
    ipconfig /flushdns
    hit enter and then type
    ipconfig /renew
    hit enter and the problem is solved.

  • PC to Mac - slower internet speed?

    I have just purchased my first mac (entry level imac 17"). I love the computer and the operating system. However, the internet speed is extremely slow (almost like dial up). I have a pc and a mac, both running off the same connection. The mac is significantly slower surfing the exact sames sites. It's not a cache issue or anything like that. The mac is just slow. I have tried both the wireless and ethernet connections and it's slow either way. I have tried downloading Firefox and that doesn't seem to make a difference either.
    Any help?
    Thanks

    Clint,
    Have you tried using the "Automatic" setting that you first saw after setup? Unless you made changes to it, I'd imagine it's still in effect, just not active since you're now using another "Location:" setting. Or, was that "Automatic" setup too slow as well?
    If you'd like to try yet again, using the same basics as included in the Network Setup Assistant, but with more stringent settings:))
    There's no need to dump any of your current setups that already work - at System Preferences>Network in the "Location:" selector simply use "New Location..." to name yourself yet another new setup (perhaps "wireless Feb 11") and proceed:
    Set the "Show:" selector to "AirPort" and choose the "TCP/IP" pane. Check that "Configure IPv4:" is set as "Using DHCP." No other settings are necessary on that preference pane. If you make any change, be sure to click the "Apply Now" button before leaving that preference pane.
    Switching from the "TCP/IP" pane to the "PPPoE" pane, if the isp connection settings are already held within your wireless router, which I think they most likely are, the "Connect using PPoE" box should not be checked. There would also be no need to have checked the box "Show PPPoE status in menu bar." If you make any change, again be sure to click the "Apply Now" button before leaving that preference pane.
    Now switching from the "PPPoE" pane to the "AirPort" pane, have the box "Show AirPort status in menu bar" checked, and I suggest setting the "By default, join:" selector to "Preferred networks." Eliminate all other networks listed [remember, you'll only be eliminating them from this new location setup, not from your other, already working "location" setups], then add your wireless network security method, name and password to the preferred networks list, and click the "Apply Now" button.
    Then within the "Options..." button, I would set the "If no preferred networks are found:" selector to "Keep looking for recent networks" and check the box "Require administrator password to Change wireless networks." I would definitely NOT check the "Automatically add new networks" box. Click the "OK" button and again the "Apply Now" button.
    Now switch the "Show:" selector from "AirPort" to "Network Port Configurations" and drag the activated "AirPort" configuration to the top of the list. Once again click the "Apply Now" button.
    Even with this new setup now activated, when you open the menu bar AirPort icon you will continue to see the other wireless networks in your area that are visible to your AirPort - but you won't have to worry about them confusing your Network connection, as it will no longer be considering them.
    To return to one of your previous connection setups, simply switch the "Location:" selector to the one you want to use, and click the "Apply Now" button. The new setup just completed will remain unchanged in the "Location:" selector under the new name chosen.
    Now, in the "Location:" selector name a second "New Location..." (such as "enet to router Feb 11") - this will be for ethernet access to your router.
    Set "Show:" to "Built-in Ethernet" and select the "TCP/IP" pane. Check that "Configure IPv4:" is set as "Using DHCP." No other settings are necessary on that pane. If you make any change, be sure to click the "Apply Now" button before leaving that preference pane.
    Switching from the TCP/IP pane to the PPPoE pane, if the isp connection settings are already held within your wireless router, which I think they most likely are, the "Connect using PPoE" box should not be checked. There would also be no need to have checked the box "Show PPPoE status in menu bar." If you make any change, again be sure to click the "Apply Now" button before leaving that preference pane.
    Now switching from the "PPPoE" pane to the "Ethernet" pane, check that the "Configure:" selector is set to "Automatically" and if any change is made, click the "Apply Now" button.
    Now switch the "Show:" selector from "Built-in Ethernet" to "Network Port Configurations" and drag the activated "Built-in Ethernet" configuration to the top of the list. Then drag the activated "AirPort" configuration to the position immediately under "Built-in Ethernet." Once again click the "Apply Now" button and that new setup is completed and activated. Your iMac will be connected to the router by ethernet and at the same time can use wireless to connect to a wireless printer or to another wireless computer.
    After both new setups are in place, I suggest to boot from your Install Disc 1, get past the first (language selection) screen, and (after fully loading) the second screen will contain a "Utilities" pull-down in the menu bar. Open and select Disk Utility. On the left side of the box, select the top-most drive shown, on the right side select "First Aid" and then click the "Verify Disk" or "Repair Disk" button. Allow to run to completion. Run a second time to be sure. Do not run Disk Permissions Repairs, but instead quit the installer version of Disk Utility, quit the installer process, and restart to your usual startup disk, which you can re-select using "Startup Disk" also located in the "Utilities" pull-down where you found Disk Utility. After restarting, Repair Disk Permissions in a similar manner after opening the version of Disk Utility located in your Applications>Utilites folder.
    Please don't hesitate to let me know the results of the above series of recommendations.
    However, if all that doesn't make for some improvement, I'd think you'd want to check with your router maker's website (or the router supplier's website if it was supplied by your isp) to see if there's a firmware update that might be applied to your router. Such an update might help your router's encryption capabilities, or might provide updated Mac support for the Intel-based Macs.
    Beyond that, I'd be calling AppleCare for support with your connection, since you're still within the 90 days of AppleCare phone support that is part of your new Mac purchase.

  • Slow Internet Speed C50-30

    I recently purchased a Lenovo C50-30 Desktop and my internet speed is very slow. I have my old computer next to it and it runs just fine on the internet (Using wireless connection). Any ideas on how to increase the internet speed for the Lenovo? Thanks

    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.
    Restart the router and the broadband device, if they're separate. Any change?
    Run Software Update and install all available updates for OS X or the computer's firmware. Any change?
    Are you connected to Ethernet as well as Wi-Fi? If so, disconnect the Ethernet cable or adapter and test.
    If possible, connect to the router with an Ethernet cable and turn off Wi-Fi. Any difference?
    Are any other devices on the network, and if so, are they the same?
    If you can connect to more than one network, are they all the same?
    Are all network applications affected, or only some? If only some, which ones?
    Is networking always the same, or is the problem intermittent?
    Disconnect all other devices from the network. Any change?
    Start up in safe mode and test. Any difference?
    Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?
    If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?

  • Wrt32on slow internet speed two computers

    I have two desk top computers with one dsl hook up with a wrt32on router so one computer can share dsl..When one computer is running internet speed is fine...when using both computers at the same time, both slow down to 1minute and 50 seconds when you chick any action you want the computer to do while on the internet...any suggestions on how to fix this?

    Use either a MoCa link as suggested above, or better yet just use Ethernet. I wouldn't bother with Wireless, as much as a different router (N-based) might improve the experience.

  • Slow Internet Speed

    For the last 2 months I have had a problem with slow broadband speed. I have tried everything to fix it here... I have the Home Hub plugged into the master socket. I have tried a different router, different cables nothing I do changes the speed.
    We have had two BT Open Reach engineers come to our house to try and solve the problem no ones knows what the problem is. When they do the test everything passes. The sync speed is around 5 Mbps but we get no where near that. They rest my profile and still no difference in speed.
    It's not been working since July... Each day they ring us a say they run tests.. The fault has been put though to our engineering team... Nothing changes though.

  • Slow internet speed/ dropping internet

    I am on the Bt Ifinity 2,  last year at summer time (8/10/2014) every thing was fine 59 mb/s down 19.55 mb/s up. bettween then and the 11/11/2014 speeds fell to 13.8mb/s down 10.24mb/s up. (mediafire link for page download for internet speeds http://www.mediafire.com/download/24vs7ra8pyl09qc/bt+stats.rar )
    during this time untill the 19/11/2014 the internet would just drop randomly, 3,5,6 times a day commonly (not shown on the graph for due to no internet). the internet droped and the router was not connected to the internet shown by the ui in 192.168.1.254. internet speed is lower then the what was on the speed test so would strugle to steam youtube videos.
    i thought that this was a throtling thing origionaly, but i tryed off peak time 1-4 AM the connection dropped slow speeds 
    we called a bt enginer out for the 19/11/2014 we a router replacement and some line was changed there was no internet dropping untill reasontly speeds increased slightly. 
    8/1/2015 I was downloading addons for battlefeild on my playstaion when the internet started dropping again the internet speed on speedtest.net showed a resonable speed of 30mb/s down 1.97mb/s up which should be fine for content consumption. well thats what i thought, youtube videos in 240p would not play. 
    in my oppinion it looks like bt has being throtiling my traffic, but i know bt only "manages p2p taffic during peak times"
    any one know whats wrong, by the way there is know other users on the network at the time of the speed tests 
    Thanks for reading 

    Next time your speeds are bad, or right now if they are now, please try this:
    In order to rule out the Homehub as potentially being the device responsible for your speed loss, you can connect the Openreach modem directly to the PC and see if the speed improves.
    To do that follow these steps:
    Step 1: Remove the homehub from the modem cable
    Step2: Connect your pc/laptop to the modem via the cable instead
    Step3: Open network and sharing centre on windows and click set up a new connection or network
    Step4: Connect to the internet then click make a new connection Broadband PPPoE
    Step5: Username [email protected] and the password as BT
    Step6: connect, If it doesn't,keep pressing try again until it does.
    However, please note that this will stop any other access apart from the PC

  • Slow internet speeds on iMac running 10.10.3

    Hey folks,
    Hoping you can help me!
    I have a late 2012 21.5" iMac running 10.10.3 and currently I've been getting very slow internet.
    I've done some troubleshooting:
    I've taken it to the Genius Bar and the airport card is fine.
    I've reset dhcp lease which used to work but now no longer does.
    Currently, my internet only gets normal speeds (about 100 Mbps down) when I delete my system config folder. Even after deleting it, however, it's only fine for a short period of time (usually a few hours) before it goes back to crawling speeds (usually the speed test ping test fails).
    It's definitely not the hardware of the machine because it's picking up the wifi, it's not the router because the speeds are fine on my other devices and fine when I delete the system config folder, so I know it's software related. The issue does persist in a guest user or known good account so I know it's not user repeated.
    I wanted to see if anyone else has any ideas to resolve the issue in the OS' current state prior to me just doing an erase and install.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
