Losing Connectivity Every Couple Of Hours / Modem Or Router?
Sep 19, 2012
I have an issue with my current network where every couple of hours I will lose my connectivity and it will not come back unless I do a power cycle on my router/modem. I originally thought the issue was with my router, however I'm beginning to think it's an issue involving the modem. I've tried two different routers and this happens on both. My main router is a D-Link WBR-1310 (crap I know but it was free) and has lasted for years, and my modem is a Toshiba PCX2500 from Time Warner Cable. The second router I used to test this was an older Linksys BEFW11S4. I was going to replace my router, but when I saw that both of them reset after a few hours (today was only 5, last night it was connected for over 8 hours as I slept). I ran an IPCONFIG /ALL when I was connected with internet and when I was connected without and the only three changes were: [code]
I have noticed that in my router log that the router opes a port automatically without any human interaction and after some the time router closes the port again.Here is the log file of my router that opens the port and close it after a couple of hours.

I have a Linsys E3200 router for almost a year. It's been working fine until recently. It kept losing internet connection every a couple hours or even shorter. I have to power cycle the router in order to make it to work. However, sometimes that won't work either. I also tried to restore the router to the factory default but that doesn't seem to work.
I have updated the router with the latest firmware (1.04). I am using a cable connection and it never gives me any problem if I just connect my computer to it. I also test my network with another old netgear router that works just fine.
I have a problem with my wag120n and iphone or ipad or macbook.The connection works well for about 1-2 hours then stops.so with macbook i have to disable airport and connect to the network again with iPad or iPhone i have to turn-off and REturn-on the wifi.I have already changed the wireless channel but this didn't work form me.
There are 3 laptops in my house including mine, and i keep losing network/internet access every couple of minutes so I have to go to the router, unplug the device, and plug the device back in every couple of minutes, usually 10-15, although it varies, and the same has been going on with the two other laptops, so it's not just my laptop.
I have been using DIR 615 at home for around one year. Now I notice that after some time of continuous usage (say around 3 4 hours) the Wireless network is lost. Thereafter only reboot brings it back. I checked for any latest firmware upgrade from admin page, but it says device already has the latest.
Any problems with the guest network on the ea4500 with the cloud firmware? I am losing guest clients after about 24 hours and the re-authentication fails. you enter the guest password and nothing happens until you reboot the router.
I have a problem with an internet connection with a customer.They have a Zyxel 660 in bridge mode and the public ip is delivered to the eth0/0 outside interface of a 5505 ASA.They lose internet connectivity a couple of times per hour. What solves the problem immediately is disconnecting the ethernet cable from the eth0/0 and then directly plugging it back. Then it runs for 20-30 minutes or so.The isp doesnt't notice any errors on the dsl connection, only that they cannot ping the outside interface from time to time (duhhh)However, yesterday, when problem appeared for first time , I noticed that this Zyxel was very hot since it was placed on top of the ASA. Now it is set apart.In the meantime I already replaced all cables, but I think it's the Zyxel so I urged that the ISP send a new Zyxel.Though it sounds strange. [code]
The issue is the connection gets interrupted and dropped, but the devices and the router DHCP clients table show the connections are still present. By interruption, I mean no data traffic is being transmitted.My wife's iPhone 4G and my son's iPod Touch wifi both show they are connected to the home network, complete with wifi bars being displayed, and the checkmark is present next to the home network connection in the the device settings for both. When I check the E3000 DHCP clients table, both Apple devices are listed as holding a connection. Yet both devices display network errors when trying to use any app that connects to the internet. By restarting the wifi connection on each, the connection is restored to the point where traffic now transmits. My wife and son estimate it is after about 10 minutes that they encounter the interruptions.
On the PC and NetBook, the connections have to be terminated and reconnected. I have not timed these to see how long before the connection becomes problematic.Interestingly, my ASUS laptop and my iPhone 4G do not have the issue, nor does my work laptop (Dell).There are no timeout parameters in the router config. Closest thing to it is the Beacon Interval, but I don't know which way to adjust it (up or down) to manage the devices that are experiencing interruptions. I have not made any interval adjustments...at this time, everything is set to default settings.This E3000 replaced an aging WRT54 (hardware v2) router so that I could have an N router in the house.
Recently it has been really slow (less than 300kb/s) and I am tired of it. I want to use wired again but the modem and router are in my basement. Running an Ethernet cable from the router to my room is a last resort. I currently have Cox Internet, Telephone, and Cable. I do have a cable supplying internet to my room, so that is not my concern. How can I move my modem and router without losing phone service? Can it be any phone cable or does it have to be one connected to a special outlet as the modem currently is?
Noticed the last couple days that pages weren't loading on my laptop. Looked at the network status for the laptop and noticed that my network speeds would fluctuate from 54Mbps to 1Mbps, and various speeds in between. I had never had this happen before (I've had this router, a Linksys, for about 6 years). I thought maybe something was going on with the laptop. Grabbed my wife's laptop and she had the same issue. So, I checked the wired towers - their speeds are running at 100% all the time, no fluctuation. So, it has to be something with my router, but I'm not familiar with how to diagnose, etc. The router has a 3rd party firmware (DD-WRT) flashed on it, in case that matters. But I've had that on there about 4 years, nothing new. I've done a DHCP release and renew.
ISP : ShawPC >> SMC Modem/Router >> Netgear Router >> PS3 and Denon Stereo Receiver ( Both hardwired to Netgear Router), 2 Laptops and 2 Phones connected wireless- The reason I do not use the SMC as a router is because I was getting terrible wireless signal- When everything is working properly I am getting great speedsroblem : I keep losing internet connectivity. On the wireless devices I still have have great signal strength but no connectivity. I need to run netgear genie oripconfig/release/renew to get it back. It always comes back but this is annoying.It also does this on the PS3 and Denon which are hardwired to the router..as with the other ones if I reset the router or do a connection test on the PS3 it will fix it. Finds IP but no internet connectivity.My PC has also started to lose connectivity and I need to do a ip release/renew and it comes back fine.The fact that this is happeneing on my PC would lead me to believe that it may be an issue with the Modem/router. Are there some settings I need to change on it since I am only using it for modem purposes? I have disabled the wireless on it but I don't think that would be the issue anyways
I have a DIR-625 router that has been acting odd lately. Several times a day at random my devices (laptop, android phones, PS3) will lose internet connectivity from my wireless network. They say they are still connected to the network but I am unable to access the internet or even the router config page. Everything works fine on Wired LAN computers. The only way I can fix it is by unplugging the router for a few seconds. I have had the router for over a year now without this problem. Seems like it may have started when we got our android phones.
I am having an intermittent problem with my network connection dropping out for no apparent reason.When it drops, I still see the lights blinking on the NIC card, but cannot pass packets even to the router.Windows does not report the connection or the cable as disconnected when this problem is occurring.The problem will persist until I disconnect and reconnect the CAT-5e wire, or disable and re-enable the NIC.As soon as I do one of those 2 things, connectivity immediately returns (and works for another hour or so).I am running a legitimate copy of Windows 7 Home Premium 64-bit on an HP Pavilion.All of the latest Windows updates and the latest firmware drivers are installed.My ethernet connection is a wired Local Area Connection with a static IP address, gateway and DNS.The IP address, gateway and DNS settings are accurate and work for several other computers here.[CODE]
I have a UC520 in a building with several IP phones. We installed a WLC526 and two AP521's for seamless roaming of cordless phones. THe phones work great with no issues. When I am running a ping test on a wireless laptop, i keep loosing packets. It looses connectivity randomnly. DHCP is given via Windows 2008R2 server. Have a cisco 2948 switch also in the mix. THe AP's are connected directly to teh front of the UC520. Why do phones work perfectly and not data?
our autonomous 1252APs. It loses network connectivity irregularly and ends up disconnecting everyone. It may stay up from a few days to a few weeks. I don't see any log messages that give any clues to why it is doing this. We have 30 of these working worldwide (on the same software level and same config) and this is the only one having the problem.
Things I have tried: Changing software levels - there is a code level where it didn't seem to have this issue, but I can't run it because then I'm unable to monitor it in our monitoring system. Swapping out wireless access pointsRe-terminating the cable on the AP side, it was really difficult to get the network cable into the AP while swapping it outBlocking a company test piece of equipment from connecting using the mac address filtering (it connects with one of their test IPs - weird) – I still see it connecting though I don't see high utilization on the switch port when the issue happens I had a few cases open with TAC, and they were unable to find anything wrong - gave them sh techs of prior to the event and after the event. It was one of those where the tickets were open for a weeks with no updates.

Network fixes I have attempted from the OS level so far include:
~ Switching the dynamic port range to start at 10,000 and run for approximately 54,000 ports
~ Systematically reviewing every running service to make certain that only the essential ones are on
~ Disabling all NIC stacks except Client for Microsoft Networks, IPv4, File and Printer Sharing and Comodo
~ Attempted connections with Comodo turned completely off and its NIC driver disabled
~ Attempted rolling back the RealTek driver to an earlier one from the same family and device line
Using netsh I have tried the following settings:
~ netsh winsock reset catalog ~ netsh int ipv4 reset reset.log ~ netsh int ipv6 reset reset.log ~ netsh int tcp set global rss=enabled
I have the model AE1200 usb adapter and its been working great for over 6 months, but lately it has been inconsistently working. It has stopped working then i have to reset the adapter and then it will work for a little bit and then it will do it again. is this a common problem or is it likely my adapter is failing? Is there an update that i am missing?
I recently purchased a Belkin F5D8053 N Wireless USB Adapter after my 6 year old adapter was unable to see my home network in the network list.
I installed the software but the adapter wouldn't connect to my home network so I reinstalled and updated the driver, still wouldn't work. Finally about 2 hours later it just randomly connected. Now it has been frequently (1-2 times a day) losing connection to my home network for around 3 hours, it can see a dozen networks in the list with full signal strength but won't connect to any at all then connects to my home network again several hours later.
I have switched between the Windows connector and the Belkin one and tried all 6 USB slots with no luck. I contacted Belkin support and they told me to try the device on another computer and see if the problem still happens but I don't have another computer to test it with.
I suspect this is a problem with my Windows installation rather than the hardware or router as my old card would freeze once every couple of days and was only fixed by powering off my computer as Windows was unable to kill the process to restart it.
I have a cisco 1941 ISR router and I am trying to configure a router to allow a modem for "Offband or Out of band" access.Below is the configuration on Aux port on Line (n):
line aux 0 login local modem InOut transport input all speed 115200 flowcontrol hardware
I have US Robotics 56k Faxmodem which is connected to aux port of router and I am using USB dialup modem with my laptop to dailin to the router which is connected to a US Robotics Faxmodem. Then I have accessed my USB dialup modem throught HyperTerminal and I can issue all "at" commands and to dialin to the modem I have used the following command atdt914011111111 (atdt followed by country code, area code and landline number)Once I issue the above command it give me message "Connected" and after this I just get a flashing cursor. I cannot do anything nor will it display a username login prompt.

First of all, this is how my connection looks like:
PC & Xbox 360 -> Router (Linksys WRT54GL with DD-WRT firmware) -> Modem (Arris TM602B) Everything is working just fine, except for every now and then (sometimes a few times per day), when my modem decides to "stop working" for a second or two. I do not know if it is exactly the modem, but i guess that it is.
What happens, is that for a second or two, all the lights on modem stop blinking or turns off, except "Power", "DS" and "US". Those lights stays turned on. After a second or two, all the lights continues working normally.
It would not even be that big of an issue, as i would not mind if my internet radio has stopped working for a second or if i had to wait a second before continuing with browsing the web, but it becomes an annoying issue, while i am playing video games on Xbox Live. This is what causes me to disconnect from an online game, even though, everything works normally after - until it happens again.
Every few minutes my WGR614v6 loses connection to the cable modem though the wireless in-house is strong. Cable modem being reset does not work. Resetting netgear router brings us back online but only for a few minutes. Have replaced power supply to router and it is still occurring.We have a desktop and 2 laptops online. Also, the notebooks always drop to 18mbps while the desktop stays at 54mbps.
Trying to figure out if I have a bad modem or bad wiring leading to the modem.I'm losing connectivity usually in the evening when I'm sure everything is more loaded.he reason I'm concerned about the modem is that when I lose connectivity, I can't access the modem through my browser. It won't respond. This isn't just for a moment. I'll unplug the modem and plug it back in. I can access the modem after that with my browser, but more often than not, I don't regain connectivity. It keeps trying and failiing.its a Motorola SB5100 from 10 years ago. how to seperate bad wiring from a bad modem?
I want to use cisco connect with the Router E1200. There is a wireless connection between laptop and E1200 Router. When I run the "Cisco Connect" after couple minutes searching It can not find the Router and I have to put an (Router name SSID) and password.

I just upgraded to a faster internet speed with my cable company, and so they came and installed a new combination modem/ wireless router yesterday. Since then my computer has said that it is connected to the internet but when I try to load pages sometimes they work and sometimes they don't. Mostly they don't work, and when they do they are very slow and don't always load pictures, video, etc. The other computers and devices in my network have no problem with the internet connection. My computer connected perfectly before the new modem was installed, and it works when it is plugged in directly ( it was plugged in the entire time the cable guy was setting up the network). I tried running the diagnostic tool and sometimes it says that the dns server isn't responding and other times it says it can't find the problem or that it can't find any problem.
I am using two desktops. One is an old Windows XP running SP3, and the other is a new Windows 7. Neither PC is wireless. I set up the modem through the Windows 7 computer, and it is connected to the wireless modem through the Ethernet cable. (I hope that I am saying all of this correctly.) It's running just fine.Because the other PC is not wireless, I purchased a NETGEAR wireless USB adapter, go through installation and setup, starts and finds my SSID, add WEP key, etc, etc. In the bottom corner of the software it says the signal is good. In the toolbar it says the adapter is connected to the modem.Next to it, though, the network connections icon shows:
Wireless Network Connection Speed: 24Mbps Signal Strength: Good Status: Limited or no connectivity
And so, of course, I have no connection to the Internet. Using the modem through Ethernet on the XP computer (switching the situation around, in other words) is not an option; the only phone line for connecting the modem to the wall is too far away.(It was stated more than once that I should use WPA instead of WEP; I haven't made it that far yet... I'm just trying to get this other computer connected.)
I bought this Tenda wifi router and connected it.It's a chinese one and the user interface is not much friendly. It works fine but sometimes if u play around with it u will lose the settings you inserted in to it and you will need to reconfigure it.
My problem is my ISP seems to renew the IP's issued to their customers automatically every 10 hrs from the last login. But every other router keeps the connection alive but my router doesn't. It needs to be restarted in order to get the internet back online.simply said,u need to restart the router every 10 hrs.
My D-Link DIR-655 will no longer let me pull up any web pages after several hours. For example, it works great when first rebooted, but the next morning web pages have timed out. When it is broken, I'm unable to connect to web pages via another wireless access point that i've plugged into the D-Link. I'm unable to use any of the wireless PCs or devices in my house.After it's rebooted, it works well for at least a few hours. It has the latest firmware and has basic, out of the box settings.
I have a Dell Inspiron, Windows 7 laptop, that's about all I know about it. A couple months ago I got a Belkin Surf N300 router, when I first got it I had it set up through Hughes Net and everything worked fine, I had good connecting everywhere I went with my laptop. Now, I no longer have the Hughes Net and I hooked up through a Broadband thing, our desktop computer is connect to it and works perfectly fine, when I go to try and connect to it on my laptop it WILL NOT work, it just says its unable to connect to it. I have tried EVERYTHING I can think of and some stuff I didn't even know you could change, all I want is to use my laptop
I have my D-link DIR 600 and I never had problems with it until now. For the past three weeks, my router keeps on disconnecting my Desktop P.C. from which the main internet cable is connected. Whenever it happens, I try connecting my Netbook over a WiFi connection using the same router; and even though my desktop can not connect to the internet, my netbook still can. Apparently when it happens, the [3] (the 4th light in the image) light goes off, and I have to restart my Desktop P.C. for it to turn on again and to use the internet again.
