Linksys WRT54GS Ver 5 needs reboot every 10-12 hours after wiring it to LG BD590 Blu-Ray

Had this router hard wired to a desktop - everything has been fine forever.  Moved it so I could hard wire it to the Blu-Ray player for watching Netflix, etc.  Everything works.  Except the Router needs to be rebooted every 10-12 hours.  Unplugging it for 30 seconds works.  The router seems to be working, but the wireless signal to the other computers in the house, although showing strong, will not connect to the internet, Router is getting its internet straight from the Comcast modem. I have the latest firmware installed in the router.  Any ideas greatly appreciated before I throw this thing out.

Try to re-flash the firmware on your router.
Connect the computer with the Ethernet cable to the router.
Download the latest firmware from Linksys website and save it on your computer. Open the setup page of the router. Click on Administration tab and go to Firmware upgrade sub tab. Browse the firmware file that you have already downloaded and upgrade it on your router.
After upgrading the firmware on the router, it is recommended that you should reset the router and reconfigure it. Press and hold the reset button on the router for 30 seconds. Release the reset button and wait for 30 seconds. Power cycle the router and reconfigure it.
Also try to change some advanced wireless settings on the router. Click on Wireless tab and go to Advanced wireless settings. Change the Beacon interval to 75, RTS threshold to 2307 and fragmentation threshold to 2306. Save the settings.

    Hello this is happening to us also (minus the Bluetooth speaker).  We can't figure out what is causing the data usage.  I turned off mobile data as soon s I activated the device, and got the message that unless I am connected to WiFi.....(that is exactly what I wanted). We watched Netflix for about three hours, then the alerts started.  Like you we have many devices connected and never used over 2GB now all of a sudden we have used it in a matter of hours.  My husband called Verizon  and got the usual doubting Thomas response.  I understand that they don't know my device settings.  So over the phone we check all the settings and turned  off every possible culprit eating up the data and end the call.  By now I have purchased another gig for the month!  Assured we are NOT using mobile data, we continue on the IE path to bliss.  HA!  A few hours later I check the mobile data usage on the Verizon website and that darn thing is still using data.  After two more phone calls and two VERY uneventful trips to the local store we were told to take out the sim card.  This has stopped the data usage, but it defeats the purpose of having the data plan.  I could have just stuck with my Surface.  Verizon sent us a new sim card.  Its been installed and I have set my homepage to Verizon mobile data usage (just kidding) but I am on that site a lot.   I am surprised at the number of complaints about this device.  When we called the Verizon support acted as though this was the first time they had heard about this.   Loved your post, you should write for a living.

  • E1000 Dies After Streaming from Mac to Apple TV - Needs Reboot Every Time

    Hey everyone:
    I got an Apple TV a few weeks back and we've been using it a lot, especially to stream Netflix.  However, another application that I got it for was for streaming iPhoto slideshows and iMovie stuff to the Apple TV with Airplay's screen sharing.  This event scenario has played out several times.....  Screen sharing is up and going and it'll be working great.  All of a sudden the TV will go back to the main Apple TV menu on its own.  Upon further review at this point, NONE of my WiFi (iPhone, iPad, etc.) devices will connect to the network and I have to power cycle the router.  Router lights are on, but no one's home.  At this point, it'll boot back up and then everything will be fine, at least for a while.
    Tonight, I was showing vacation pictures to some family and this same process happened twice.  Since I can't seem to figure out how to stop playing a slideshow in iPhoto and then start it again in the middle, it's very annoying.  Here are some relevant troubleshooting points to consider:
    1.  This network problem (or something similar to it) has happened in the past, but whatever it is, streaming a slideshow really seems to aggravate it.  This seems to be the only scenario that I can do to actually INDUCE the issue.  Periods of long uploads or downloads are fine.  Streaming audio from one device and similar usage seems to be fine, but this scenario fails pretty much every time, and not necessarily right away.
    2.  After having this issue tonight multiple times, I stopped trying to stream an actual iPhoto slideshow and just went into the album and scrolled through the pics one by one.  I did this for at least an hour with no issue.  But with an actual slideshow, it failed twice in 30 minutes or less.  And it's happened before tonight as well.
    3.  It doesn't appear to make a difference what application I'm streaming from on the Mac.  Whether it's iPhoto, iMovie, or even Facetime.  
    MacBook Pro Specs - OS X 10.8.2 - Late 2011 Model
    Apple TV - MD199LL/A, v5.0.2
    Router - Linksys/Cisci E1000 - Firmware v2.1.02
    Anyone else have similar experiences or advice?  I've got a fair amount of devices in my home that use WiFi, but there was nothing irregular going on in the house to generate an excessive amount of internal network traffic or anything like that.  My gut says the problem is with the router, but it's only a few months old, and I've updated the firmware to no avail. 
    Thanks a bunch for any advice you may have!

    OK, so I've done a couple things here and both point to the above post about having two devices doing AirPlay at once.
    First things first....  I ran the Inssider tool and looked over my network.  My signal seems to always be between 50 and 60.  My router is on Ch 6 which seems to be the best choice.  There's one other network on that channel, but it's a very low signal strength.  The other ends of the spectrum are pretty well covered by other networks.
    Does this shed any light on this problem?
    Second - I hard wired my MacBook to the router, then screen shared to the Apple TV.  It was up for at least 15 minutes.  At some point, I looked over and it was no longer sharing, but the network *WASN'T* trashed like it normally gets.  So it possibly got dropped for some other reason.
    Third - I forgot that I have an Apple Airport Express that I normally use to stream music to a radio in my garage.  However, this device can be used as a router.  So I set it up this way and created a 2nd network.  I only put the Macbook and the Apple TV on it.  I've been streaming continuously for about 35 minutes now with no issues. 
    So it would seem that there's a firmware issue with this router that won't allow one device to Airplay to another device.  Does anyone else have any other conclusions or suggestions?  Otherwise, looks like I'll be treating myself to some new hardware after Christmas.
    Thanks very much for your help!

  • Wrt54g ver 7 getting dced every 10mins or so.

    i checked, my internet connection has n problem. whenever i connect my cable modem into the router the connection will get disconnected every few mins and will connect aft 10 sec or so. this is killing me as i need the constant internet connection. help pls?

    Have you connected your Modem directly to your computer and have you check if the Internet is working fine on your computer?
    Are you facing this problem on your Wired computer or on your Wireless Computer?
    If its working fine, then login to the setup page of your Router and below change the MTU size to 1350 and click on Save Settings...

  • Linksys WRT54G Ver.6 not connecting (but internet is working through modem)?

    I have the following router and the internet is not working through it though its working when I connect my Mac directly to the ISP's modem.
    I did update the router to the latest firmware, I have had this router for the past 4 years. My friends other computer which is a vista and my iPhone is not able to get the Internet either. But it's connecting to the network with strong signal
    status I'm able to see the ip adress,subnet mask etc
    please help

    As you upgraded the router's firmware,Reset the router and try to re-configure it from scratch.

  • IMac constantly hanging up - needs reboot every few hours

    I'm running an i5 iMac currently when I play WoW. Usually I only have Safari and iTunes open at the same time. My iStat tells me GPU temps are around 80 celsius and CPU temps at 55 celsius. When I'm playing WoW for an hour or two, everything on my display will freeze up, but I can still move the mouse pointer around. The music from iTunes keeps playing as well but keys and etc are unresponsive.
    My first thought was that it was a GPU heating issue so I tried out smcFan control, which bumped my GPU temps down to 62 celsius and CPU temps of 45 celsius.
    Is anyone else having these issues or know of any possible solutions? Thanks for your time.

    yes i had the same exact problem, now my imac will not boot at all.
    do you think it was a heating issue?

  • WRT54G ver.2

    A couple weeks ago very soon after a snow storm my wireless kept disconnecting after repeat re-powering. I contacted the ISP because of their long history of various issues and figured it had to do with weather and service signal. They said it was fine when they checked it over the telephone. Then they sent a technician. He said their signal and their modem were functioning good. He continued to say my Linksys router was the problem. They told me this numerous times before over the last couple of years and repeatedly it was their issue and they finally fixed it with many technician visits and discoveries. So, I was inclined to think here we go again. If I connect my computer direct to their modem I get a consistent connection to the internet, no interruptions, normal, using it now. If I connect through the Linksys WRT54G ver.2 router either wireless or to the hard wired network system the service repeatedly fails rather quickly after re-powering and the 3 green lights to the far left flash fast simultaneously. Is this diagnostic for anything? I'm know inclined to believe the issue may be the router.  I am going to try the "Hard Reset" suggested to another poster. Thanks for any help. Bill Hite Jr. 

    Yes, you can try to reset the router and reconfigure it.
    Also try to upgrade the firmware on your router.
    Connect the modem to the Internet port and computer to Ethernet port on the router.
    Download the latest firmware from Linksys website and save it on your computer.
    Open the setup page of the router and go to Administration tab. Click on Firmware upgrade sub tab. Browse the firmware file that you have already downloaded and upgrade it on your router.
    After upgrading the firmware on your router it is recommended that you should reset the router.
    Press and hold the reset button on the router for 30 seconds. Release the reset button and wait for 30 seconds. Power cycle the router and try to reconfigure it.

  • IMac loses wireless network connection intermittently - Linksys wrt54g v.5

    I' ve setup a new 17" iMac for my folks, runs great with this big exception - it will spontaneously, but regularly lose connectivity with my Linksys WRT54G v.5 router (usually after sleep, but not always - and sometimes when starting cold). Restarting the iMac, fidgeting with internet connect, etc. will not fix the problem. ONLY power cycling the Linksys router will allow the iMac to once again see the network. Once the router is recycled, the network reappears with its strong signal indicator in the menubar (the iMac is maybe 20 feet from the router). When connected, network performance and quality are at expected levels (ie, no slow d/l speeds etc.).
    To make it interesting, I also have a PC running XPsp2, that experiences NO network hiccups when the iMac loses connectivity. And the iMac does this whether or not the PC is on, etc. But if I turn the PC on when the iMac cannot connect, the PC has no problem joining the network or accessing resources.
    In otherwords, I sense a problem between the Linksys router and the iMac (either the Airport card or OS X).
    I HAVE upgraded the Linksys firmware, upgraded all Apple software, changed router channels, and tried both WEP and WPA Personal, all to the same result. I have also scoured every corner of Apple and Linksys boards, only to find many people with this same issue and no answers.
    Brownie points for answers!

    Well, so far so good!
    I would never have found the preferences, so thank you thank you thank you for that Sherry. I never did delete ALL the prefs, just the ones obviously labeled as network related. But so far, no dropouts for 2.5 days. If Apple has anything up detailing this procedure, I sure couldn't find it - so you saved me there. I thought we left all the "delete prefs" solutions behind with OS 9.
    BUT, I was a bad boy and actually made two changes at once. Not recommended procedure, I know, but I was desperate. In addition to deleting/recreating the above prefs, I also changed the router from Channel 1 to Channel 11. Maybe the Airport card likes Chan. 11 in this application? Dunno if this was part of the solution, but worhwhile info for anyone else in the same situation.

  • How do I configure my Airport to work well with a Linksys WRT54G?

    I have DSL Extreme coming into my house in bridge mode. (Don't know the specifics, but they said that's how it has to work.) I had my Airport Extreme connected to the modem, sending out a nice wireless signal.
    I was given a Linksys WRT54G Ver. 6 wireless router, and I thought I'd use it as the main router connected the modem. I also want to use it as a wireless access point for one half the house for b/g devices AND I also want to set up the Airport Extreme as another wired access point for the other half of the house for n devices.
    So, I set up the Linksys as the main router sending out a wireless signal on channel 1 for b/g devices. I connected the WAN port of the Airport to one of the open LAN ports on the Linksys, changed the Airport to Bridge mode, and set up a new wirelss network to broadcast on a different channel. Unfortunately, this isn't working. Only the Linksys wireless is working properly, i.e. connected to the internet. The Airport broadcasts the wireless signal, but it isn't connecting to the internet.
    I've tried changing the IP address of the Airport to one that falls within the range of the Linksys (192.168.1.x) and making sure that the subnet of the Airport is identical to the Linksys. I've also added the DNS servers, although I'm not sure why the Airport Admin Utility asked for this. Regardless, nothing works. I'll get a green light, but there's no connectivity to the internet.
    I've also tried connecting to a LAN port and not the WAN port on the Airport. No joy there.
    I've read through numerous threads, and they all seem to indicate that my original set up should work. I've upgraded my Linksys firmware, to no avail. I don't want the Airport to be a repeater as there is a reduction in speed. I want to have two separate wireless access points.
    Thanks in advance for any and all help.

    Ok, I got you. Prior to the introduction of the simultaneous dual-band routers, the only way to mimic them was exactly what you are trying to do. Connect two routers by Ethernet and create separate wireless networks to allow clients to connect to either as appropriate.
    You are also correct that the upstream router (Linksys) should have both NAT & DHCP enabled and that the downstream router (AirPort) be configured as a bridge. The only recommendation is to set the AirPort's static Private IP address to one just outside of the Linksys' DHCP server range instead of inside it to prevent the same IP address being handed out to multiple clients.
    You could do this a number of ways, but the simplest would be to use the Configure IPv4 = Manually option on the TCP/IP tab within the AirPort Utility. Use the LAN-side IP address of the Linksys for the Router Address, and the appropriate DNS server addresses (either your ISP's or a service like OpenDNS). The Domain Name field can be left blank.
    Since the AirPort is in bridge mode, it really doesn't matter which Ethernet port (WAN or LAN) you connect the Linksys to, but for consistency, I would recommend the WAN (circle-of-dots) port.

  • WRT54GX2 reboots every 10 seconds

    I have a linksys WRT54GX2 wireless router that reboots every 10 seconds. I've read that it's a firmware problem but how am I supposed to update the firmware from the interface in a matter of 10 seconds?

    You can try updating the firmware using TFTP utility...BUt before you upgrade the firmware...Press and hold the reset button for 60 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...
    Download the TFTP utility and save it on the dekstop.
    Follow these steps to upgrade the firmware on the device : -
    Double click the TFTP.exe file and click run.
    For Server- Enter the IP Address of the router that you assigned.  By default, the router is 192.168.1.1...
    For Password- Enter the password you assigned the router. By default, the router’s password is “admin”.
    For File- Click the triple “…” button and browse for the .bin firmware file...
    Click Upgrade button to start upgrading.  A progress bar should show up to show the progress.
    Once the Upgrade is done press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

  • Access restrictions w/ WRT54G Ver 8 (Firmware 8.0.5).......

    It seems that Access Restrictions are a bit of a problem w/ the Linksys routers. Well, here's my story to go with the crowd. Hopefully, someone at Linksys / Cisco can provide a solution.
    I am wanting to set up access restrictions on my Linksys WRT54G Ver. 8 (Firmware 8.0.5). Following the "instructions", I built my access restrictions as follows:
    Policy 1
    Enabled
    Named for my PC
    Edited List of PC's - inserted my NIC MAC address and saved the settings
    Set to "Allow" Internet Access
    Everyday
    24 Hrs per day
    Saved Settings
    Policy 2
    Enabled
    Named for my daughters laptop
    Edited List of PC's - inserted her Wireless NIC MAC address and saved the settings
    Set to "Allow" Internet Access
    Sun - Thur: 07:00 AM - 09:30 PM
    Fri - Sat: 07:00 AM - 10:00 PM
    Saved Settings
    Policy 3
    Enabled Named for my wife's desktop
    Edited List of PC's - inserted her NIC MAC address and saved the settings
    Set to "Allow" Internet Access
    Sun - Sat: 06:00 AM - 11:00 PM
    Saved Settings
    ....then, I reset the router. Once up, I tried access from each PC...nothing. Couldn't get out.
    Thus, I went back into the Linksys set up, disabled the access restrictions. Viola ! I'm back on-line with all three PC's.
    Checked around the forum and found that some people had built a primary policy that included all of their PC MAC's or IP addresses and was "Enabled" and set to "Deny" Internet access 24/7. From there, they built out their access restrictions and, supposedly, they worked.
    I tried that as well...deleted all the access restrictions. Reset the router and went through the entire router setup to be on the safe side. Built the primary "Deny" access restriction then my other three PC restrictions. And....it still didn't work.
    Thus, I would really like to get this working so I can limit my daughters access. It's interfering with her school work so I want to lock her down a little bit. Friends are important to her but I've stressed that her education is even more important.
     Thus, if Linksys themselves or someone on the forums can provide an answer, excellent ! If not, I'll look into another router that can do the job. I'd rather not do that, but if the Linksys won't perform this function, I'll have to. Thanks in advance for any feedback.

    Thanks for the reply. I deleted all profiles and built just the two specific for my daughters laptop and one for my wife's PC. My wife's PC is running XP SP3. It follows the access restriction policy with no problems. My daughters laptop is running Vista Home Premium. With the policies active, her connectivity was sporadic for about an hour before it just finally shut off her connectivity completely...well before the policy was supposed to.
    Thus, I'm now thinking that thismay be a Vista problem to an extent as well(Gee....who would have thought that !?!?!?!?).
    I disabled the IP 6 protocol just as a precaution. Still no access. And when I disable the policies on the Linksys, she's back in service.
    Any further suggestions are appreciated.

  • WRT54G ver . 5 and AppleTV

    I seem to be having an issue with multicast between the wired ports on a LinkSys WRT54G ver. 5 and an AppleTV which is on the wireless network. The Bonjour service, which I believe uses multicast, seems to not be able to cross the boundry from wired to wireless on the router.
    For instance, I typically use an iPhone connected wirelessly to my WRT54G to control my AppleTV, also on the wireless network, but if I move the AppleTV to a wired port, the iPhone cannot see the AppleTV anymore even though both can go out to the internet via the cable modem plugged into the WRT54G.
    Any ideas? I just updated to the most recent version of the firmware, 1.02.7

    WRT54G v5 does not support WMM feature...I would suggest you to either go for N-Series router like WRT160N or upgrade the router with 3rd party firmware like dd-wrt.However upgrading the router with 3rd party firmware will void the warranty period of the router.

  • WRT54G Ver 6 Constant Need To Reset!

    I purchased a WRT54G Ver 6.0 Router in April to bring to Iraq with me.  I have it connected to my iDirect 3000 Satellite Modem, with the static IP config input into the WRT54G.
    I have two computers on my desk, my personnal XPS 1710 with Vista and my Work D600 Latitude with XP.  Both computers exhibit the same problems at the same time.  I have even had other computers connected and have had the same problem.
    My problem seems to be a constant need to reset the WRT54G Router.  I was connecting wirelessly.  The system seemed to operate fine for a day or two.  I started to have problems with the connection to the internet dropping.  When it did this, I could not connect to the WRT54G setup page either.  I figured something locally here at the Camp in Iraq might have been interfering with the wireless, so I ditched the wireless and have been using wired connections.  The problems have not stopped.  I am constantly having to unplug and reset the router to reconnect.  When it hangs up, I cannot even connect to the setup page.  Occasionally, it will find itself without reseting the router, but most times, I have to reset.
    I have tried factory default reseting and manually reentering my settings.  I have just updated the firmware, but it didn't seem to solve anything.  In the past few minutes while trying to search for this problem here on this forum, the router dropped the connection twice.  The networking icon on the computer still indicates a connection, on the Vista is shows that a local connection is available only (during the problem).
    I have read a little online and this seems to be a common problem for Linksys.  I have 2 more of these routers, one at home and one at my office in the States.  Both have had the problems, just not as severe.  This router requires reseting at least 15 times a day during my 12 hour shift.
    I bought the Linksys Routers because they did have a reputation for reliability and quality.  Boy, I guess I should have researched this one a bit more.
    I have 5 IP addresses from my Satellite ISP, so I am considering configuring the Router as a Switch or HUB, but I am unsure on how to do this, or of it will even solve my problems.
    Any ideas?
    Thanks,
    Vincent

    I am having the almost exactly the same problem. It started about a week ago, (just like alot of others I have read on here recently) and I too will have no access to the set up page once it drops the net. I can still acess other computers on the router, but no net and no router set-up page until I reset it. I'm running the same router, without the firmware update. I have 4 desktops directly into the router..and one laptop wireless. Most of the time, the net will stay on for all the computers for surfing and email. Maybe once or twice a day it will drop access to the internet. a simple unplugging of the power cord resets it and everything is peachy. BUT....try to start a download.(usind DAP *download accelerator plus* or a bit torrent)...WHOA! it's anywhere from an instant drop to maybe ten minutes then drop. Most assuredly it will drop. we have had this router since January, and until a week ago, it worked just fine. no problems. Last week, our ISP upgraded their equipment and increased the bandwidth. (we have to use a cellular connection with a static IP being out in the boonies far enough that cable and DSL are still not available) The problems started at the same time and I thought it might be a problem with them. After testing one of the computers with a direct connection to the internet modem, everything, including a major download, worked just fine. It is definately a router problem. I spent quite a lengthy time on the phone with Linksys tech support, and the nice lady had me change the MTU rate from 1500 to 1300. It seemed to work, but about an hour after being done with the support call, things started to go wonky again. I am just about at my wits end!! Nothing has been changed on the router settings except that one thing that tech support instructed me to do. I am kinda leary about upgrading the firmware because I have been seeing a ton of *my router wont work with firmware update* or *now my router is frozen* posts. I have to type in a ton of settings because I am using a static IP and I really don't want to do all that again!! lol PLEASE, somone have a solution to this problem! It is driving me mad!! I would really hate to have to buy a new router, but my roomate is about to that point if this doesn't get fixed soon.
