One machine connecting very slow on home network

Hi,
I have what appears to be a werid situation. I have, at this very moment, an iBook G4, an iMac G4 and an iMac G5 all connected via Airort (Extreme) to an Airport Express (which is on the net). The iBook and the iMac G5 all connect quite quickly (2 Mbps). The iMac G4 connects at less then 20 kbits per second.
There appears, I think, to be some networking setting "out of whack" which is causing it to network very slowly. (or, another possibility, is that the Airport card is damaged).
I have looked (by comparing the sick machine to the good machines) at every network setting I could think of, but, to no avail.
I have all three machines side by side. I am running a DSL speed test. The two good machines clock in at 2 Mbps, the sick machine at 20 kbps.
They are all using Airport (Extreme) to talk to the same AE.
Weird.
Tom

Follow up information...
When I chcked the "Interference Robustness" option on the Airport menu item, the problem resolved itself. The iMac G4 is now as fast (over 2 Mbps) on my DSL connection as the iBook G4 two feet to the left and the iMac G5 two feet to the right.
Odd as it seems, three machines on a desk, one required that option the other two did not.

  • IMessage slows entire home network when sending images?

    Does anyone have a CLUE why a picture sent through iMessage when on WiFi would slow down my internet connection accross my whole home network? For example run a ping test and I get normal 25ms pings to google.com > send picture on iPhone on WiFi > ping jumps to 300+... AGAIN THIS IS A PICTURE NOT A HUGE VIDEO.........
    Sidenote: before you say its my router, this issue was present on my old router. I will take a look at any suggestions but highly doubt that its a router issue.
    Phone: iPhone 5 White
    Carrier: AT&T
    ISP: Wide Open West
    Bandwith: 15mbs down | 1mbs up

    That's pretty common in the US. It's the ISP's being cheap, basically. They assume that home users have no need to upload large quantities of data, just download. And 90+% of the time, that's true. Unfortunately, it's easy to overwhelm a 1 Mbps uplink. If it only lasts a few seconds, it's not a big deal.
    It doesn't matter how large the files are. The only thing that matters is whether you saturate the connection. Things like facetime are self limiting. They only generate data so fast. File uploads, on the other hand, will cram as much as they can fit up the pipe.

  • IMac won't connect to MBP on home network

    I have an iMac and a MacBook Pro at home on the same network. The iMac is connected by ethernet, the MBP by wireless. The MBP can see the iMac under the shared list in Finder. I can select and browse folders. The issue is on the iMac. I can see the MBP but when I try and connect it just hangs. Occasionally I do connect but all the folder I try and browse have a red circles and won't let me access.
    I have tried deleting the com.apple.finder.plist file and logging out/logging in on both machines. This did not fix the problem. Any help is appreciated.

    I came on here to post the same - or similar issue.
    My iMac G5 sees but fails to connect via airport and home network to my Macbook. Macbook connects to iMac no problem.
    I tried connecting them directly via ethernet, same result. iMac sees but fails to connect to Macbook; Macbook connects to iMac.
    This has happened before and has worked itself out (although I don't know how).
    Yesterday, I did an Onyx clean up and maintenance.

  • Ipad will no longer connect to my private home network

    i have always had my ipad mini connected to my private home network for over a year and just 3 days ago it no longer connects to my network! Why is that and how can i fix it???
    i have no problems with my iphone 4s! it still connects to my wifi!

    If you are having WiFi problems it is necessary to isolate whether the problem is with your network or your iPad. Note: Do NOT consider your network to be blameless if some other devices can connect to it.
    First, test your iPad on some other WiFi networks: a friends, Starbucks, Barnes & Noble, etc.
    If it works well there then the problem is probably with your network. Try restarting your WiFi router by removing power for 30 seconds. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.
    If your iPad does not function well on other networks it possibly has a hardware problem. You could try Settings > General > Reset > Reset Network Settings to see if that corrects the problem. If not, contact Apple Support or visit an Apple store for evaluation. They can provide a replacement if your iPad is bad.
    If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

  • TS1398 My ipad will not connect to other wifi networks. It has connected to my main home network but will not connect to the booster network in my home (it has previously!) It will also not connect to other networks outside my home.

    Hi
    I just got new router and had to reset my network settings on IPad. Since then, my ipad will connect onto the main home network but will not attach to my extension booster (netgear) which is linked to the home network. It will also not attach to networks outside my home that it has previously worked with. i have reset the settings again, powered off and on again, updated to the latest IOS update, but nothing is working. Please help, as I can only use wifi in a few rooms in my house and i do not have 3G on my my ipad.

    Did you try forgetting the network and starting all over again?
    Settings>WiFi>Network Name>Tap the blue arrow>Forget this Network. Restart your iPad and then try joining again.
    Try rebooting your router. Even though everything else may be connecting to your Network, it might help with the iPad. Unplug the router for about 30 seconds and then plug it in again.
    Reset Network settings on the iPad?
    Settings>>General>Reset>Reset Network Settings. You will have to start all over again, Tap WiFi in the settings, find your network and enter the password.

  • Network connection very slow, lot of drops

    Hello!
    On my network, there's an ADSL modem; an AirPort Extreme is connected to it and all my computers are connected to that AirPort Extreme.
    Initially, I had set the AirPort Extreme as a bridge and the modem was in PPPoE. However, I had weird troubles with that setup (one computer couldn't reach another one, not even ping) so I made the other way around: the modem is now in bridge mode and the AirPort Extreme handles the PPPoE connection.
    Since then (at least, I guess), downloading from the Internet or simply browsing is a nightmare. Connections would start at a varying low rate (always less than 30 KB/s, sometimes 5 KB/s) and always slow down until the connection drops completely. For small files, I can hope to download a 1 MB file in 40 minutes; for larger ones, it's hopeless.
    I've tried to rule out the AirPort Extreme, connecting one computer directly to the modem. I reset the modem (since it's in bridge mode and it's beyond the subnet made from the AirPort Extreme, how can I reach it from my network?) and enter my ISP data. When all the lights on the modem are fine, it tells me some tests failed; I can't connect to the Internet that way. It looks like the modem lost its ability to connect as PPPoE when I defined it as a bridge (?).
    I then tried to rule out the modem. I connected my computer and the ADSL line to the AirPort Extreme (which still had the PPPoE settings); the AirPort Extreme would not connect or reach a DNS (what's the purpose of having PPPoE settings if it can't connect to the Internet without even passing by a modem in bridge mode?).
    In short, I can't rule out either the modem nor the AirPort Extreme, because they both can't connect to the Internet separately (the modem could before I inverted which device is in bridge mode). After all my attempts, the only way to get Internet back is to set the modem again as a bridge and use the AirPort Extreme for the PPPoE, which makes the whole problem of a very slow connection (even unusable) that I'm trying to repair. I'm lost at that point.
    Any help would be really welcome!

    Two possibilities:
    1) The modem is not working correctly and should be replaced
    If that's the case, then I'm feeling guilty, as it worked before I set it as a bridge.
    2) Your log in information has changed due to service provider updates. Contact your provider to verify your account details
    It's actually my mother who created that account; I'll ask her further.
    my native language isn't English
    But, your English is excellent.
    Thank you.
    Some countries use PPPoA authentication, and not PPPoE.  Although they are similar, if your provider really uses PPPoA credentials, then you cannot log on from your Mac or use the AirPort router to provide the log on authorization, since Apple does not support PPPoA.
    Well, I tried using PPPoA recently and it wasn't better. Also, the fact that the AirPort is currently the one making the PPPoE authentication seems to definitively indicate it's not PPPoA (thanks to your information that it wouldn't work in that case).
    Generally, my opinion would be that things will work better if you use the modem or a modem/router to provide the connection service and run the AirPort in Bridge Mode.....rather than trying to put the modem in Bridge Mode and use the AirPort to provide the connection service.
    Yes, I agree. Actually, I had another problem with the previous setup (AirPort as bridge and modem for PPPoE) where, on my LAN with two computers, only one could reach the other one (the connection worked in one direction only); I couldn't even use file sharing, Remote Desktop or even ping (because, even trying from the working sense, the response would often not come back). In this Apple forum, I got the suggestion to exchange which device was in bridge mode and, indeed, now I can communicate from and to all computers. Since I've realised my connection to the Internet is now mostly broken, I should have been satisfied with the previous problem…
    I'm hoping to go back to an Internet connection that works, and not get the first issue of computers not being reachable on the LAN. The big trouble here is that all these behaviours I've experienced are weird (am I outside of the logic with my use of the devices?). I'm also noticing that the first problem sounds to have arrived since I replaced my old router by the AirPort Extreme.
    If your modem is 4-5 years old, then that might be another reason to consider replacing it.  Ask your provider what they would recommend.
    Wow, mine is actually way older than that! I don't think we've ever changed it since we had an Internet connection (around 1998). At this time, things were not designed to break too soon, right?
    Perhaps it had to break with this duration of use, and it just waited that I change settings to break… Doesn't sound a likely scenario, however.
    I'm considering trying with my neighbour's modem (with his connection's settings), with the AirPort in bridge mode. If it works, I'll be almost certain the problem is the modem, I'm right?
    Thank you very much for your help so far; things are getting clearer!

  • One user has very slow network drives on terminal server.

    Hello,
    I am using a windows XP machine to connect to a 2003 terminal server. I have one user that was complaining about how long it took her to open files from a network share. I found that this is a problem with her account as it is slow no matter where she logs
    in from. E.G when I log in to the server from my computer as me, it is quite fast, if I do the same but log in as her it is painfully slow accessing the network drives.
    Does anyone has any ideas?Kind regards,
    Chris

    Hi Chris,
    Thank you for your comment.
    The issue seems it’s related to network problem, please check the network connection behavior. Network performance issues can also be caused by auto-tuning, because not all network devices support auto-tuning well. So try to disable the autotunning behavior
    with below mention command and check the result.
    netsh int tcp set global autotuninglevel=disabled
    In addition check KB 885189 for slowness mapped drive issue to Server 2003. Apart from this, check the below article to make the network connection fast.
    Windows 7 Network Slow
    Hope it helps!
    Thanks,

  • IOS7 on iPhone 4s: Since I have iOS7, my 4s connects very slow (or not at all) to a known Wi-Fi access point (e.g. at home). This this a bug?

    Since I have installed iOS7 on my iPhone 4s - 16G, my 4s connects very slowly to my home Wi-Fi network. Sometimes it even doesn't connects at all. Which result in a higher mobile data usage (and thus higher bill at the end of the month).
    Can this error be solved in iOS 7.0.4?

  • TimeCapsule 2.4ghz connection VERY slow

    For the past several days, any connection to the 2.4Ghz radio on my TC is very slow.  Speedtest.net shows .29Mbps download and .34Mbps upload (yes, note the decimal place!).  If I switch over to the 5Ghz radio, my speeds increase to 16.03Mbps download and 4.19Mbps upload.  Also, when connected to the 5Ghz radio, my laptop is showing a full 4 bars of strength, whereas when connect to 2.4 radio, I am only getting 1-2 bars from the same location.
    The TC is connected to my Comcast cable modem - wired connections through the TC are getting 30+Mbps downloads.
    I have tried restarting TC, restarting the cable modem, rebooting client machines...
    Ideas?  is my 2.4Ghz radio dying?

    Chances are, your router is just fine and you are picking up some interference on the overcrowded 2.4 GHz band from a cordless phone, other neraby wireless network, or a wireless camera/security system.
    I used to have intermittent slow downs and drop outs on my old 2.4 GHz router and never could figure out why. One day at my desk, by accident I noticed my neighbor coming out of his front door talking on his cordless phone wihen my wireless suddenly slowed. When he got to his mailbox on the street, the wireless was down to a crawl.
    So, the source of the interference may not necessarily be in your home, although if you have any cordless phones, that would be the first thing to investigate. For more info on the epidemic problem of wireless interference, you might want to look over this document:

  • WRT54G2 - very slow at home, blazing fast at work. Any idea why?

    I have a WRT54G2 wireless router at home with a Verizon DSL internet connection.  In the last week or two my internet speed has been very, very slow.  I hooked up my laptop to the DSL modem with a network cable and the speed of the connection was fine.  I brought the WRT54G2 into my office and swapped it with  the office wireless router (Comcast cable internet connection) and the WRT54G2 worked without any problems.  The connection here in my office is absolutely fine with both wireless routers, and in fact using Speedtest.net the router from home was faster than the one in the office.
    Any ideas what would be causing the difference in connection speeds between home and office locations?  If my DSL modem is giving a good connection with a wired connection I am guessing the problem was  with the wireless router, but in the office it performs flawlessly.

    At your Home you are using DSL connection (Verizon) and at your Office you are using Comcast (Cable) ISP. The modem which you have got from your Verizon it also has a DHCP in it. So when you connect your Linksys router to your Verizon Modem, so your connection will be Like NAT behind NAT issue. So in this case when you connect your Linksys router to your Verizon Modem the speed will be slow as compared to your Office.
    So you can Call up your ISP and convert your modem into bridge mode, and i think this might solve your problem.And you will receive a good speed from your router.

  • Lumia 920 Facebook connection very slow over WiFi ...

    Since the Portico update the connection to Facebook both in the People and Me hub as well as in the Facebook app is very slow over WiFi, whilst still good over 4G/LTE (with WiFi off). The connection to the Nokia account also appears to have a similar problem. All other accounts and apps have good speed over both cellular and WiFi connections.
    Any ideas anybody?
    PS: FYI, a bit more info about the history and context: When I noticed the problem the first time after the update, I tried to solve it by deleting and re-adding my Facebook account on the phone. Unfortunately, that made me lose my Me hub tile, so I decided to do a full reset. That again unfortunately got stuck on the togg wheels, so I restored the phone using Nokia Care Suite with the latest firmware, and restored my accounts, apps and settings from scratch. Everythings seems to work fine now, except the above mentioned Facebook and Nokia account connectivity problem.

    Did you somehow solve this problem?
    I have the same issue here with my Lumia 920.
    However I have already found out that it only applies to my home Wifi. All other Wifi networks i was connecting to did work flawlesly.
    I need to note that all other devices on my home network are using facebook without a glitch. Only Lumia has some problems with it.
