Dropped connection on laptop

Every other day this happens . I have router WRT54GX2. It connects directly to my desktop. My daughter has a HP laptop. Almost every other day she cannot access internet. It shows our network sometimes and sometimes it does not. It shows other networks in our area. Why does this happen so often? I must have done something right if it connects sometimes for hours.  The laptop is set for our router to be automatic. Any suggestions? BTW she is less than 20 feet from me when it still will not connect.

You may be getting radio wave interference, perhaps from your neighbors routers, or from a wireless phone (yours or your neighbors).

  • Dropped connection when using Desktop and laptop

    I have a Motorala cable modem connected to a Linksys 10/100 5-port Work Group Switch. I have my desktop connected to this switch and have a WRT5G Wireless Router connected also. The problem is that when my lap top is connected to the internet, the desktop does not connect and vice versa. When the desktop is connected, the laptop shows that there is a wireless connection, but the browser comes up saying no connection. Any advice?

    Why exactly do you have this setup? The normal setup would be cable modem connecting to router. Computers (wired and wireless) connecting to router.
    How exactly do you "connect" your desktop or laptop to the internet? What do you do to get a connection?
    What you have is two devices connected directly the modem and thus your ISP. Unless the modem is actually a modem/router this won't work if your ISP does not allow more then 1 internet connection at a time.
    I suspect this slightly setup is the actual problem. If you use the desktop, the desktop gets the IP address from the ISP. Now the desktop is using internet connection through the modem. Thus, your router cannot connect to the internet nor your laptop.
    When your router connects to the internet it gets the IP address from the ISP. Again, the desktop cannot get an IP address anymore because the internet connection is already used.
    The normal setup is that the internet port of your router is connected to the modem. The purpose of a router like the WRT is to share a single internet connection among several computers - wired and wireless.
    Therefore I would suggest you connect the internet port of the WRT to the modem directly and hook up the desktop to a LAN port of the WRT. You can also connect the switch to a LAN port. Now desktop and laptop share the internet connection established by the WRT.

  • AT&T U-verse dropping connections suddenly

    Hi all.
    Since upgrading to Yosemite, there has been a degrading of my internet reliability with AT&T U-verse, and its been getting worse and worse.  I now drop connections every HOUR.  Speed and WiFi strength are great when its working, but it will spontaneously stop working, and if i do a series of diagnostics, quitting safari, turning wifi off and on, etc., I can get back online after a few minutes.  BUT WHAT THE HECK IS HAPPENING?  At this point I've mucked around with just about every network setting so I no longer even know what they should be.  AT&T is fairly useless regarding tech support for Macs, so hopefully someone here knows the current UVerse setup and can give me some advice.  Here's where I stand:
    - I have a 2009 Mac Pro, running latest Yosemite.
    - Router is AT&T Motorola NVG589, connecting to U-verse service (not gigabit, just regular)
    - When internet service drops, it appears that the WiFi continues to be connected well, at least for a while.  The NVG589 status page still shows my machine connected, and the WiFi signal strength in the menu bar remains full strength, but Diagnostics show failure to connect to ISP and internet.  Other Devices, like my phone or other laptops, continue to connect fine, so the broadband is fine, so maybe the WiFi is only appearing to work or something else is going on.  At some point, the WiFi also stops responding until I do a bunch of restarting stuff.
    - I have already trashed the various preference files and created fresh new locations, but to no avail.  It all works fine for a while then goes spotty again.
    - I have my network prefs set to "Link-local only" which had worked fine before.
    - I set the DNS servers to 8.8.8.8 and 8.8.4.4
    I don't really know much about the various pros and cons of different settings, but apparently you can get the NVG589 to assign a static IP address (or semi-static or something like that) but is that BETTER?   would that end the dropouts?
    Any other ideas?

    Hello Javier Bonafont,
    Welcome to the Apple Support Communities!
    I understand that it can be very frustrating when you are having multiple Wi-Fi drops in signal at home. There are a couple of different troubleshooting steps that I would recommend in this situation. Please refer to the attached article for information and steps to help you troubleshoot this situation.
    Wi-Fi: How to troubleshoot Wi-Fi connectivity - Apple Support
    Symptom: The network connection drops unexpectedly
    Your Mac may not not stay connected to your Wi-Fi network reliably.
    Your Mac may stop accessing the Internet during use.
    Solution
    Use these steps if your computer disconnects from its Wi-Fi network unexpectedly.
    Check your range to the Wi-Fi router and reduce the effect of interference.If your computer is too far from your Wi-Fi router or your environment has too much Wi-Fi interference, then your computer may not detect the Wi-Fi network properly. The easiest way to check for range limits with your Wi-Fi network is to move your computer or your Wi-Fi router closer together and make sure that there are no obstructions (such as walls, cabinets, and so forth) between the router and your computer.See Potential sources of wireless interference for more information about interference and solutions.
    Try connecting to a different Wi-Fi network. If your computer works fine when connected to a different Wi-Fi network, then the issue may be related to your network router or ISP. In that case, contact the manufacturer of your router or your ISP.
    Best regards,
    Joe

  • Apple TV3 dropping connection from iTunes...

    Hi there,
    I've read a lot of issues on the same thing but I wonder if anyone is having the same issue as me.
    Thinking it was a hardware problem I secured a replacement from the store but I'm having the same issue.
    I have a PC, Windows 8
    BT Infinity (with their home hub, I'm UK based)
    My Apple TV is wired directly to the hub (I have also adjusted the settings to give the Apple static IP addresses, I've also tried it with automatic IP)
    If I boot everything up from scratch the Apple TV will play both music and my movies (both my DVD rips and those purchased from iTunes store and downloaded to the PC).
    However, let's say when I've done the above I decide to watch a movie that is on the PC, it works and I can watch the full film or even a TV program.  Then I decide I want to watch another film after viewing that one, that's when I get the spinning wheel.  The Apple TV will recognise my iTunes library and display the movies but unless I watch something on the cloud I cannot view what's on my PC hard drive.  Then after a bit the Apple is telling me to turn on home sharing.  It already is on and my PC has no sleep settings activated, I turned them all off so unless I power down nothing will enter sleep mode or even powersave.
    I then have to reboot the PC and open iTunes again.
    Like I mentioned I've taken the first one back for an exchange, the same problem persists.  I've also been on the phone to Apple who advised to power everything down for 5 minutes then turn the router back on followed by the Apple then the PC.  That worked, so I then left it for 5 minutes and then the problem happened again when I decided to watch a film that I put on my PC hard drive.  It seems that I have to choose what I want to do quickly but it wont work with further requests after something is played. 
    I am using the inbuilt virus checker that comes with Win 8 (Elements I think it's called) and I use Windows Firewall.  I have tried creating a rule to allow iTunes to connect out on the firewall settings but this did nothing.  I've tired automatic IP addresses and now trying static ones but again, no joy.  Bonjour has been uninstalled, reinstalled, opened up connections in the firewall, basically everything I've read on this issue I've done.
    I read somewhere about turning off the Dolby Stereo, and yes, you guessed it, nothing corrected it.
    Has anyone had this problem exactly and any idea how to overcome it.  Apple have suggested a clean reinstall of my PC, so I tried it, wiped everything and started again.  Nothing, so I tried it on my laptop which has Windows 7 and it seems it's not localised to just one specific version of Windows.
    Getting a bit fed up now! 
    As a last ditch attempt I also checked the serial number to see if it was an old unit that needed to be replaced but it's not.  Oh, and I have also tried wireless and wired.  That didn't change anything.
    One interesting thing though, when looking at the settings for the BT Home Hub and looking at devices, when I know the Apple TV is connected it's showing as not connected.  It appears as though it is dropping connection after it has perhaps synced the whole film from the PC.  I can't think of a way to force it to stay connected.
    Any suggestions?

    UPDATE
    This is now resolved, not with the use of the Homehub though.
    After another conversation with Apple they asked me if the Youtube app on the TV works, which it does then there's a problem elsewhere!  Therefore Apple think there's an issue with the hub or the home network.  They also asked me to try something on the hub called Port Forwarding.  However, because that the hub isn't an Apple product they are not allowed to advise me on tinkering with the settings.  But did suggest to Google a website called port forwarding. 
    Having a look at that I tried what it suggested by connecting to the BT Homehub, you guessed it, that didn't work either.  I called BT who advised that their technical help team that would deal with this has been disbanded and the person I spoke to gave me the port forwarding suggestion on Google.
    At this stage I had had enough and after reading a few more bits of feedback I then looked at replacing the hub with something I could buy myself.  This led me to Amazon where I purchased the ASUS RT-N56U and a modem to go with it.  I ripped out the hub and linked the modem to the line in the wall and the router to the modem, I had to bridge the router to the modem and after that was done I set up the wireless.
    I'm now very pleased to say that it works, everything is syncing as it should do and the speeds of my downloads have also increased.  So far no issues at all.  I also have a constant connection to the PC and can view as many films as I want that are downloaded to the PC.  No lagging, no problems at all.
    Bit of an expensive solution but the modem and router I bought can also replace a Virgin one should I change suppliers in the future.
    If you follow this solution and are doing it the same with BT just Google the username for the hubs as it's the same for everyone, you can get that username from the hub if you connect to it but if you're like me and didn't think of that all the solutions you can google.  I used the CD's that came with the items and I had it all set up and running in 5 minutes.  If you do purchase the RT-N56U don't forget you need a modem, as that bit I forgot about and then had to order that via Amazon as well.
    That's really all you need!

  • FiOS Quantum Gateway Router - Intermittent Dropped Connections

    I just got this router and incredibly disappointed!! I had the Arcotec.. Excuse my spelling and was having intermittent problems with that but this new a Gateway is herendous!!! I can't believe they charge you a 199 for this. Wifi signal lost constantly. Called tech support.. Now they want to charge me 75 bucks for an extender that they say will help.. Optimum looking better all the time!! Very frustrated.

    I am experiencing the exact same issue. My issue also started after i upgraded to their 50/50 plan and swapped out my Actiontech M42xxx for the Quantum Gateway Router. They had me do the following and i am still having the issue. 1. disconnect the coaxial cable and the power from the router2. Reset the fios box in my garage by unscrewing the battery power and removing the battery3. Replaced the router (Verizon did this and the replacement was another Quantum Gateway)4. Replaced the box in my garage (Verizon did this)keleko68 wrote:
    Hi All, I upgraded my FiOS service a couple of weeks ago to the Quantum 50/50 service and bought the Quantum Gateway/router (model# FiOS-G1100). I used to use the Actiontec router (model# MI424WR, Rev. I). I've been having issues probably for months with intermittent or dropped connections on both wired and wireless connections. Fast forward to the beginning of December. I called tech support enough to the point of them sending a tech out to look at it. My ONT was old, and he replaced it. I had hoped that this was the issue, but it wasn't. The drop-offs continued. I again hoped the upgrade in service and router would also fix the issue. Nope... didn't. This 'latest, most powerful' router only has two lights on it, one for wireless signal and the other that looks like a globe. The router sits on my desk, so I can watch the lights.  While I am surfing around, the globe light will suddenly flash for about 5-10 seconds. While this is happening, my connection drops/stops, and then resumes a couple of seconds after the globe light stops blinking. I also noticed that the globe light will turn red once in a while, but not nearly as often as the blinking white does. It's not really consistent as to how long I can be online before the connection starts dropping. I haven't honestly watched it for a long period of time (in other words, I don't know if it's still doing it while I'm not at the computer). I just notice it while I'm trying to use the connection. Once the router starts disconnecting, it can happen as often as every few minutes. VERY annoying. My setup is:2 Mac laptops (one used wirelessly and one used wired connected to a display)1 Apple TV (wired)1 Apple Airport Express (wired)1 printer (wired) I don't have any cordless phones, powerline adapters, wifi extenders, or other electronics that might be messing with the signal. I use VPN software but haven't noticed a difference with it on or off (I think). Any thoughts as to what this might be or where to look? Thanks in advance.       I am still having the issue. there is obviously an issue and either Verizon knows about it and doesn't want to say they know there is an issue and fix it, or they are too dumb to take the time to find out. Each time i call i give them detailed information on the issue and ask them to check their knowledgebase if its listed as a know issue and they keep saying it's not. The issue happened again tonight, 1/8/15. at first my laptop dropped Internet connection while i was surfing. then i checked my other wi-fi devices and they all lost connection. i then went and checked my wired devices and they too lost connection. I look at the router and this time both the Globe Internet and the Wi-Fi lights were solid white. i looked at the Internet Ethernet light and the bottom light was green. I could have resolved the issue by unplugging the router and plug it in back, but instead i called Verizon so they could see the issue. 10 minutes into the Verizon call queue the Globe Internet light changed from solid white to solid red. 5 minutes later i finally got to speak to a tech. at first he said the box in my garage wasn't connecting to the router and asked me to disconnect the coaxial cable and the power and, according to him, he sent some command and instructed me to connect the coaxial cable and power the router back on. I did that and then the issue went away.I told him the rootcause of the issue was not identified and fixed and the issue would occur again and i needed him to alert engineering or product development about the issue. i then told him its a know issue with the router and he should do a google with "Verizon Quantum Gateway dropping connection" and he would see how many people are having the same issue. I told him Verizon need to take their heads out their A*%%%$ and spend some time and investigate and resolve the issue. Me

  • Time capsule drops connection

  • E4200 - Extremely high latency, drops connections

    I have 50mb high speed Internet via comcast using a docsys 3 modem, and my wired connection is blazingly fast. I am more than happy to pay for performance, thus this purchase. And that's precisely why it's so infuriating to have 5 to 10 seconds of waiting for a web page to even BEGIN to load via the wireless network. Something is seriously wrong with this router - probably the firmware - even though I'm up to date (I called to double check)
    Once connections are made, the transfer is impressive. But I'm not sure the 5+ seconds to start each connection is worth it.

    There might be some settings required in the router so that it gets the proper solution. If you are facing the concern of getting lag, dropped connections then you can try the following steps:
    A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
    1] Open the software and go to the option which says "Router Settings"
    2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
    3] Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page)
    4] Then go to the Wireless tab, keep network mode as mixed,
    For Channel Settings of 2.4 GHz you can make Channel Width to 20 MHz only and Channel to 6, 9, 11..
    For Channel Settings of 5 GHz you can make Channel Width to 20 MHz only and Channel to 40 or 161...
    B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the username field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.
    You should also make sure you upgrade the drivers for the WLAN card on your laptop computers.
    Second, for best results, wireless-N routers should be paired with wireless-N adapters in the same way that wireless-G routers should be paired with wireless-G adapters.
    Should there be a mix of wireless-G and wireless-N adapters connecting to the network, it would be best to set the wireless network mode to Mixed. This will allow wireless-G devices to have a stable connection to the network and will allow the wireless-N device to still connect to the network but will be performing based on the wireless-G speed.

  • Wrt54gs drops connection

    Forgive me if this has been addressed somewhere on here - i looked for a similar situation and couldnt find one--this is wordy, but hopefully it is useful info to solve the issue.
    My future father-in-law runs a Sony Vaio with Windows XP with SP2, on Charter hi-speed internet through a Motorola cable modem.  virus and firewall are from Trend Micro.  Comp and modem are approx 5 years old. They just got a WRT54GS (v. 7 i believe) and had no problems setting it up right out of the gate - he used the LELA interface and was up and running in no time.  all night it was fine.  The problems started the next day, when they tried to get on the internet.  Their homepage is MSN, and it wouldnt load up.  they also tried to go to several of thier regularly visited websites, nothing worked.  Eventually they gave up and disconnected the router, going directly through the old modem.  that let them back online for about an hour, then it dropped the connection and they couldnt get it back. finally, they un-installed the LELA software and everything was back to normal.
    My future F-I-L wanted to be able to work from home with his laptop, which was the whole reasone for the router, so this weekend i went over to set everything back up.  We got the router re-installed, everything was communciating properly, and they were back in business.  His laptop was at work, so i planned to go over today to get that connected.  when i got there, they informed me that they couldnt get on the internet anymore.  yesterday was fine, nobody tried to get on during the day, and this evening the problem started.
    I checked connections (all good), un-hooked the router, and had the same non access problems, so i dumped the software as well.  read a bit online and then re-installed everything, it wouldnt let me onto the internet, so i went into the router and changed the IP to 192.168.2.1.  released the DHCP and renewed it, and everything was great.
    Then tried to connect the laptop (ibm thinkpad, win XP SP2) had some troubles, mis-entered the WAP key, fixed that, and got on the internet with the laptop.  Everything seemed good, but when he tried to access his work server (via LotusNotes) it wouldnt allow him in.  something about the tcp/ip being denied.
    The laptop is running PcAnywhere, which i have read may have issues.  One thing i noticed is that LELA recognized the laptop twice.  once as an actual computer with the right name, and once as an unknown device.  unless i disable pcAnywhere and the  IBM access connections software, the recognized laptop doesnt access the network, only the unknown device does.
    1.) Is the re-assigned IP solution the best way to handle the dropped connection?  did it even really solve the problem?
    and
    2.) is the laptop connection issue something with the router, or something with the different programs on the computer itself?

  • Broadcom wl with wext driver on Wicd dropping connections

    I have a laptop where I'm using Wicd to connect to my WPA network. My wireless card is a Broadcom Corporation BCM43142 which is, unfortunately, only supported by the "wl" driver. I can connect to my wireless alright, but every 5 to 30 minutes I get disconnected from the internet.
    My journal is littered with these stack traces. I have a feeling these are the culprits.

    Has anyone seen anything similar to this? Does anyone know if this is a Wicd, wext, or wl problem? Any help in either fixing this problem or mitigating the dropped connections would be great.

    Hi,
    I have the same issue. The stacktrace is printed everytime I connect with Wicd.
    I'm running kernel 3.19 (but it happened on 3.16 as well) and my wifi card is "Broadcom Corporation BCM43228 802.11a/b/g/n".
    DId you find a solution to the problem?

  • BT Wifi drops connections periodically

    While I'm waiting for BT to resolve the issues encountered while installing my line, I've been using BT Wifi (FON) now & then.
    I noticed this week, that after a while of being logged in (login via BT ID, not by purchasing time), after a while, the session is logged out. I actually noticed as it happened while my lad was watching a video on YouTube on the laptop.
    It's not a problem to log back in again & it works, but it is a hassle. Same problem doesn't exist when using the mobile/tablet app - so it's clearly not an account limitation.
    Anyone any ideas of the cause? Or an easy work around (don't say to install the app on the laptop... it'd be much easier/faster for me to write an auto-login script for the browser & sit it on a background page in Chrome)?
    Solved!
    Go to Solution.

    BTWIFI is set to drop connection every 2 hrs (I think) to stop people downloading large files.  it will also disconencted after 15min of inactivity

  • Linksys E2000 drops connection

    Hey everyone, I have had my Linksys E2000 for a few months now. But up until now, I havent used the wireless settings too much, I have had everything hardwired into the router. 
    I decided last week to set up the wireless settings so that I can connect my PC and Xbox's wirelessly. They are all within about 10 feet from the router. The connection is fine for a while, but after a few days it begins to degrade. I opened up a command line and pinged 192.168.1.1 to see results of 150+ms on my PC wirelessly. Wired it was about 2ms.
    All of my devices have a static IP address on the LAN, and one of my Xbox's is in the DMZ, still dropping connection often. I moved my PC and DMZ Xbox to another room on the second floor of my house and its still about the same speed.
    I set my old wireless G router up and its working fine......but I use my PC as a home media server, so 54mbps is very slow for media that needs upwards of 100+mbps. My ISP subscription is about 12mbps, which I get all 12 of those on a hardwired machine, but a wireless on the E2000 is lucky to get 3 of those.
    I have everything set up correctly in the router settings, MTU of 1500, with only Wireless N broadcasting. I also noticed that the E2000 will drop connection much faster if the SSID is hidden.My old Wireless G router is getting pings of less then 1ms wirelessly.
    I have the Xbox S models and my wireless adapter is a Edimax wireless N adapter. Could this be a defective router? Any options to try to fix the problems?

    I'm experiencing similar problems as well.  I'm going to try these settings out and see what happens.  Reseting my router fixes the problem, but I don't want to have to do this once a week or more.  My WRT54GS worked great, but I wanted the speed that N had to offer.   Its rather annoying because I hate having to go upstairs every time I need to reset my router in order to get an IP address on my wireless laptop downstairs.
    This seems to be an apparent problem among Wireless-N in general.  D-Link, Linksys and Netgear all seem to have problems with dropped wireless-N connections on their routers too. Read the reviews on Amazon & Newegg for yourself.

  • MacBook is dropping connections often

    Using OS 10.5.8 with a MacBook 4.1, using a Belkin "n" wireless routing fed from Comcast Cable modem (motorola, I think).
    If I leave the machine for even a short while, it is likely to break the wireless connection. Also on the same wireless router are a PC laptop and an iPhone 4.
    Since getting the iPhone, the dropped connections on the MacBook seem to be getting worse. No noticeable problem with the PC, or the iPhone (although we have not used the iPhone wireless apps much yet.
    Have gotten a message like this a couple times in to past couple of days
    Thanks for any pointers or clarifications?

    Does your Router have some setting like this?

  • Connection between laptop and PDA

    Hello eveyone,
    I was wondering if anyone has got an idea on how to do this...
    I am trying to design a software (Location Based) that will connect my laptop to a pocket pc Toshiba e740 using wireless technologies.
    i need to somehow send applets or java swing application to my PDA from my laptop.
    I need to use java technologies for the prgramming.
    Please has anyone got an idea on how to do this?
    Thank you

    You don't say which WIFI you are using but the following is applicable to 54g and the older standard.
    This is the nature of WIFI but you can improve matters.... If someone has one of those television transmitters that uses WIFI 2.4Ghz you are probably shot although I can report that the XBOX 360 controllers seem to exist very happily....
    Set the data rate as low as possible to support the application and also set the Fragment Threshold and RTS thresholds lower (750 from 2500).
    You may also find it helpfull to turn of auto channel hopping and fix the channel as well as turning off features such as pre-amble length detection and if there is a roaming decision parameter adjust it for distance rather than throughput. Turn it off if you can.
    I also found that fixing IP addresses routes etc. seems to help as well and it seems more tolerant of drop outs as a result.
    This is generally in the configuration parameters for the hardware.
    This will need to be done at both ends.... I suspect however that an access point would be better as the antenna location will or should be optimised That's one reason why people use them. In an industrial context the best I have seen to date is the CISCO stuff but it costs....

  • BEFW1154 v.4 - Dropped Connections

    Hi,
    I have been using a BEFW1154 v.4 wireless router for 2 years and my wife and daughter have told me they are sick of dropped connections. I don't know where the problem is.
    1. I have a Desktop PC connected to the internet with a cable modem. Wireless Router is connected to this PC.
    2. I have 2 Laptops connecting wirelessly using this Router. One Laptop is located in the next room, the other is one floor down and 30 feet away.
    3. We all use Windows XP SP2.
    4. The Laptop in the next room drops the connection at least 5 times a day and the computer freezes up. Needs to be powered down and restarted. Desktop connection is uninterupted. Occurs most often when connected to pokerstars.com.
    5. The Laptop located on another floor drops the connection at least 2 times a day. Requires pulling the power chord from the router to reset. Desktop connection is not interupted. Occurs randomly on any internet site.
    Thanks
    Tom

    Hi,there, I met the same problem. Sometimes wired connection is fine while wireless connection does not work. And in the meanwhile, I can not connect to router admin page with my wired connection. Sometimes both connections fail. I need to unplug the router power and plug in it again to make it work. But after some time, it would fail again. Could someone know how to solve this problem? My firmwire version is the highest and it is 1.52.02. Thanks!

  • SOLVED: Dropped connections with Time Capsule and cable modem/router

    I've been dealing with random dropped connections for quite a while and I thought that it would be useful to share what I've found.
    I was having a very puzzling problem where my internet connection would drop randomly on wireless devices. On my laptop, webpages would suddenly become unresponsive for a minute or two, Mail would have connection problems and complain, etc...but incredibly randomly and definitely not repeatable or in any pattern that I noticed.
    I also have 2 Nest thermostats in the house which connect via wi-fi. I noticed that they would randomly show Offline very often when viewed from a webpage or iPhone app, but the Nest front panels showed that they were connected with a strong signal.
    As I said, the dropped connections were very sporadic. Most of the time, everything worked, but every once in a while...bam.
    I worked with the level 3 tech support guys at Nest for over a week to figure out what was going on. We went through settings on my router and Time Capsule and everything seemed proper and okay. I even replaced the Nests with new ones but still had the same problem. We were all completely stumped.
    Yesterday, my laptop dropped it's connection at the same time my wife's laptop dropped hers. At this point, I wondered if something was wrong with the Time Capsule or maybe my internet provider.
    I called AppleCare to see if they could help with debugging the problem. They passed me up to a senior wi-fi tech and he asked me many questions about the configuration of my network. My home network looked like this yesterday (see crappy diagram below)
                                                         Motorola Cable modem/router
                                                                                 |
                                                           Netgear multiport switch
                                                          |          |         |         |          |
                                                         hardwired Macs,            TimeCapsule (bridge mode)
                                                         laser printers,                   |   |   |   |   |
                                                          Apple TVs                       laptops, Nest, iphones
    This configuration seemed correct to me. The Time Capsule in bridge mode would mean that the cable modem/router would be handling DHCP so all the devices would be on the same network and I could print from a laptop to one of my printers and the laptops could connect to the hardwired Macs, etc..
    The AppleCare technician said he thought that bridge mode was the problem. He mentioned that there was a known issue that in this configuration, the IP addresses could get lost between the cable modem/router and the Time Capsule. He said it would be best if the Time Capsule was in DHCP/NAT mode and the first device before the switch, this way the Time Capsule was the only device passing out IP addresses.
    So I repatched my network like this:
                                                       Motorola Cable modem/router
                                                                                 |
                                                       TimeCapsule (DHCP/NAT mode)
                                                                |                                       |   |   |   |   |
                                        Netgear multipart switch                      laptops, Nest, iphones
                                             |         |         |        |
                                               hardwired Macs,           
                                                 laser printers,                 
                                                   Apple TVs                     
    I can tell you that in the past 24 hours, I haven't seen anything lose a connection. Not even the Nests which seemed be on and off all the time. And, in this configuration, all the devices are on the same network and able to speak to each other.
    I hope that helps someone.

    So you're saying that Bridge Mode not functioning properly is a well known issue?
    Not to me.. I have not had issues with the TC in bridge. And it is my prefered setup. I think it is better as a wireless AP and network hard disk than a router any day of the week.. but there are other ways to skin the cat if it is proving unreliable. I am at the moment using a wireless bridge from the Gen4 TC to a Gen4 AE upstairs for TV internet streaming.. it started off very reliable.. but of late I guess I need to reboot it every few days. And it has required a full reset two or three times.. although I probably need to take some of the blame for those. I am not over worried.. i do not believe in wireless bridges except for the most interim of arrangements.. it will be wired in ethernet ASAP.
    Wireless should always be used in a way that respects its status as voodoo.. not stable technology. NOT SCIENCE.. it is more a bag of beads and rattles.
    Is there a way to change the cable modem/router to avoid the double NAT problem?
    The answer to this may depend on your ISP. Did they provide the modem? If so they may lock it down so you have no control. But normally a Motorola cable modem will not have a bridge mode as such but will have a method of turning off NAT.. (and wireless).. this amounts to the same thing.
    Once you turn off NAT.. you need to power cycle the modem so the TC gets the public IP in router mode. The power cycle time might be 5min or 20min or overnight.. it again depends on your ISP.. but you need to stop the modem capturing the public IP so it can be passed to the modem.
    Depending on where you are in the world.. US is most concentration of cable network.. you can go out and buy your own modem. Pick one on your ISP list and steer clear of SB.. at least with the apple routers they are problematic.
    It also can be a case that the cable modem is SB model and therefore more problematic. Sorry I have forgotten the recommendation for what to buy. There are a number of posts here about it but search is terrible now. (or I am too old to figure it out). I will get Bob to poke his nose in and tell you what works for him.
