D-Link DIR-655 :: Random Internet Disconnects From Internet

Feb 18, 2012

I am experiencing random disconnects from the internet -- they have been occurring about 1-3 times per day, although I've just had four in the last 20 minutes.

ISP: Wow! Cable - 15/1Mbps
Modem: Motorola SB6121 (new)
Router: D-Link DIR-655 (new) Firmware 2.00NA

When the internet disconnects:
- Both the LAN & the WAN are affected, but I do not lose any wireless connectivity with the router itself.
- I am able to log into the router wirelessly but cannot access the modem.
- If I plug my laptop directly into the modem, I can connect to the internet.
- When I reboot (using the on/off switch on the surge protector), everything comes back up.

There are a couple of other wireless routers nearby with fairly strong signals, but they appear to be running on different channels.

My phones are DECT 6.0, so there shouldn't be any interference problems with those.

I've been poking around this forum, and have already made some setting changes that seem to be consistently recommended:
- Ensured DNS IP addresses are being filled in under Setup/Internet/Manual
- Turned off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
- Turned off Advanced DNS Services
- Turned on DNS Relay under Setup/Networking.
- Setup DHCP reserved IP addresses for all devices on the router.
- Ensured devices are set to auto obtain an IP address.
- Set Firewall settings to Endpoint Independent for TCP and UDP.
- Using mixed G and N signal mode
- My security setting is WPA-Personal. WPA2-PSK

Internet Random Disconnects After Reformatted

Mar 2, 2013

recently upgraded most of my computer parts and reformatted from windows 7 enterprise 32bit to win7 enterprise 64bit. (all of this happened in a computer store) I never had internet problems before the reformat, however it has happened to me before when I had previous, newly reformats on my pc which usually goes away after 2-3 months. here is the problem, the internet is fine when I start using it and after an hour or two it will disconnect and when I troubleshoot it, it will just say "DNS server isn't responding" and what I do is turn the modem off and turn it back on and the internet will come back after 10-20 seconds. so basically my internet is fine and will just go down then to fix it I just have to turn the router off and on.

Linksys Wireless Router :: E4200 Disconnects Internet At Random Times

Oct 14, 2011

I check all of the settings and changed the channel to see if it works.  For some reason it disconnects my wireless internet at random times and i know before it never use to do that before with a older router. There is nothing blocking it, it worked before, and my computers can connect except two.  The only thing i can guess is my wireless card.

D-Link DIR-655 :: Random Disconnection From Internet

Feb 25, 2013

I have been experiencing random disconnection from the internet completely out of the blue lately.  Router has worked great for a long long time.  Now it just drops connection and is down for about a minute and then I can reconnect or reload a webpage.I have my xbox live and PC wired with a laptop wireless.  It drops everything at the same time everytime.  I hardwired my xbox to the modem and gamed all day.  I would assume this could eliminate the modem as an issue.  There isnt any inconsistencies with the router's colour or lights to my knowledge either.

I put a new Ethernet cable from modem to router to try and I thought it fixed the problem but it lasted problem free for about 6 hours then it crashed.

D-Link DIR-655 :: Internet Connection Being Dropped And Random Reboots

Mar 30, 2011

I've been having a number of issues with performance on my DIR-655 with streaming media, internet connection being dropped and random reboots. Over the last couple of weeks it has been getting worse, to the point where I'm about to act out the printer scene from Office Space but with my DIR-655!  It has been rebooting, completely killing WiFi networks and Internet Connection, almost every 20 minutes when I'm watching DivX over the network. The relevent information about my network is as follows:

-Hardware:
-D-Link DIR-655
-Hardware Version: A3 (US) , Firmware Version: 1.34NA

As an experiment I reconfigured the DSL-380T into PPPOE mode and set the DIR-655 into DHCP Client.  This was over 2 hrs ago.  So far - no random reboots, no jittering on the Media Center Extender playing videos, no internet drop outs..It seems to me that the DIR-655 doesn't cope well when it has to do the PPPOE network protocol as well as the routing, WiFi and other basic functionality that it should be able to cope with.I'll leave it running as it now is and report back later, but from the dramatic change in behavior I'm hoping that I've finally cracked my perf issues with the DIR-655.

D-link DIR 615 Disconnects From Internet?

Feb 3, 2011

I have a D-link DIR 615 and 2 laptops, a Toshiba (Vista) at about 35 ft away and a Dell (XP) about 15 ft away from the router. Both laptops connect to the router. The Dell w/ 4 or 5 bars and the Toshiba usually 2 bars. They stay connected to the router but lose the internet regularly. Anywhere from every day or two or 3 and 4 times a day. Usually shutting off the router for 10 seconds and turning it on again will reconnect to the internet but sometimes it takes up to 4 or more times and resetting the router before it works again. This happened when I was on a different cable network at a different address last year.

D-Link DIR-651 :: Internet Disconnects When Try To Use It

Jul 25, 2011

I brought this router mainly for audio/video streaming, as well as multiplayer gaming.  I thought it would work.  However, whenever i try to watch a show online, or even play a flash game, it would disconnect.  I've only had this router for one day.  I have Time Warner Cable as my cable provider and honestly since I'm living alone, the only two device that'll ever use the router is my laptop and my desktop.

D-Link DIR-655 :: Internet Randomly Disconnects Every Few Hours

May 12, 2011

I am using a D-Link DIR-655 REV B (Firmware: 2.00NA) wireless router. The problem I keep having is that the internet will randomly disconnect and it happens to all my computers. I am not sure if it is the router or the modem that is causing this. The internet service provider that I am using is Time Warner Cable and the modem is an ARRIS TM502G.I have tried resetting the modem and the internet seems to come back. Same thing happens if I try to reset the router instead of the modem. I have also tried restoring the router to factory default settings and that didn't seem to work.

TP-Link ADSL2+ Wireless :: TD-W8960N V3 Disconnects / DSL Light And Internet Go Off

Mar 3, 2013

Region : Egypt

Hardware Version : V1
Firmware Version : 1.4.0 Build 111108 Rel.40398n

In the past everything was working fine (had same computer connected wireless + wire) never had this disconnection. Now, I have a laptop connected using wireless & desktop wired but this disconnection is becoming so irritating. It is not only that I lose the internet connection, I lose the DSL like (as if the modem is turned off then on) and all my files over the LAN are either lost during transmission or something else.

Random Disconnects Every 2 To 30 Minutes?

Aug 12, 2012

Recently I've been experiencing random disconnects.

My setup is a Actiontec Q1000 with (QAQ002-31.20L.4) modem/router that talks to qwest. Then I connect to a linksys router WRT54G2. I connect directly to the linksys router with an ethernet cable, but my family connects to it wirelessly.

I ran a constant ping to my modem and to google, and on the random disconnect, the Actiontec Q1000 gets a huge 4000ms response time (but then it resumes normally), and I get ping timeouts to google. Windows 7 will say "no internet connection available". Not sure if it makes a difference, but I had google timeout 4 times during my constant pings.

Nobody else is connected when it does this random disconnects, so I'm not sure what's causing it. I've tried a lot of things, from changing and flushing my dns, connecting directly to the modem, turning off QoS/firewall settings, but nothing seems to work.

Centurylink Random Disconnects?

Nov 2, 2012

I just moved to a new rural city and Centurylink DSL is the only option for internet. I just had it installed on Monday and have had problems immediately. The two main problems are this:1) My computer is connected wirelessly but cannot seem to connect my mobile devices. My phone and my Google Nexus both try to obtain IP address and then immediately disconnect and try to reconnect over and over. Strangely my Kindle Fire didn't seem to have a problem.) I've found that when I am playing a game (Team Fortress 2 and World of Warcraft) and sometimes even watching a video on youtube, I will lose connection and get booted from my game or have to restart the video. The lights on the modem don't change and the modem itself does not disconnect or reboot. I seem to have internet service immediately after, but I get a hiccup probably once every 10 minutes that makes games unplayable

Via a cable, i get usually 1 ms, and sometimes 2 ms. It generates a problem while online gaming and btw i tried changing channels and it didnt work. I even get same pings when i am 3 meters away from the router compared to less than 1 ms pings.

Wired PC Randomly Disconnects From Network At Random Intervals?

Feb 11, 2013

Wired PC randomly disconnects from network at random intervals each dayoday it has done so 3 times. The only way I have found to get it working again is to reset the router which can be inconvenient. When it disconnects all wireless devices continue to work and I have no issues like this with my wired consolesI switched to using a static IP address, since having an automatic one gave me the same results [i have since switched back to automatic]Be happy for any suggestions on how to sort this. I am using W7 OS and I'm using an Orange router. I don't know if its relevant, but when I go to reset my router I have noticed that the download light on my router is flashing like crazy when my PC has disconnected.

Linksys Wireless Router :: Random Disconnects With WRT110?

Jul 28, 2011

I see that many people have the same problem, random disconnects. I am a long term sufferer from this. I have called support before they can't fix it. and being knowledgeable with routers has not worked at all. I turned off every wireless device in the house, even the microwave it still happens. I change the channel countless times it still happens.

Linksys Wireless Router :: E3200 Some Random Disconnects On Devices Using 2.4GHz Frequency

Jul 24, 2011

I just recently (4 days ago) purchased an E3200 router.  I noticed some random disconnects on my devices using the 2.4GHz frequency.I installed inSSIDer from MetaGeek to see what was going on and noticed some strange behavior where the Amplitude on the 2.4GHz randomly drops dramatically.  Sometimes its once every 10 minutes, other times it happens 5 times in one minute.  I can't figure out what is the cause.  The 5GHz signal is steady as a rock.

 What I tried so far:  Set the Channel to the least crowded channel instead of auto, upgraded the firmware, restarted the router all to no avail.  This is annoying to say the least.  It doesn't affect anything unless you are playing video games or running a remote desktop session, where a single disconnect is disastrous. I just upgraded from an old linksys wrt54g, tried a netgear n600 which was terrible, then swapped it out for the Cisco E3200..

Cisco Wireless :: 5100 / 6200 - Intel Chipset Clients Random Citrix Disconnects

Apr 24, 2012

Currently using intel 5100 & 6200 client cards on multiple driver versions. WiSM is 7.0.116. APs are 1250 and 1260 series. Citrix is setup to send server-side keepalives for session reliability. Randomly, several times a day the client will get disconnected from the Citrix application session but maintain connectivity to the AP and other applications continue to work. Traces show the server-side keepalive reach the controller but are delayed from controller to client by 5-6 seconds. Just enough time for the Citrix server to timeout and tear down to session. Additional testing shows the delay most likely occurs somewhere from controller to AP. It occurs on multiple controllers on multiple campuses.
 
We have Dell/Broadcom clients that don't experience the problem. The only commonality seems to be the Intel cards. CCX? I know Intel has a special relationship with Cisco regarding CCX and have developed features not available on other cards. Tried disabling power save and other CCX features but hasn't solved the issue.

Random Internet Lag Spikes

Jan 16, 2011

I am playing a game, like Battlefield Bad Company 2. Every 5-15 minutes, I get 3 lag spikes. When I get the lag spikes, everyone who is using my internet, also gets it the same time as me. So my computer is not the problem.For example: I am just running, shooting people (online), and then, randomly, people are running on the spot for like 3 seconds, and then they teleport somewhere in front of them. And then it goes back to normal, then it happens again. It will happen 3 times.

Random Internet Slow Downs

Mar 9, 2013

Where I try to download files and they do not download. They only download for a few seconds before not receiving any internet connection. Then after a few minutes they slowly download at only a few KB/s before completely not downloading.

Internet Slowdown And Random Disconnect

May 27, 2011

Recently I bought a new PC to replace an old laptop that I use in my bedroom. However, initially I couldn't pick up my downstairs router signal. So, I bought a new wireless network card and STILL didn't pick up any signal. I then purchased a Netgear WN200RPT and everything seemed to be ok while using that to repeat the signal up into my bedroom. Then, suddenly, it all stopped working. The WN200RPT would, although showing a full internet connection with no yellow ! or red x's, it would never ever load webpages. So, I removed it and put it back in its box. Then, for some unknown reason after a Windows 7 reinstall, my network card started picking up the signal from my home router and had a good speed and signal. This worked fine for a month or two before it started playing up again. It would randomly slow down and stop loading webpages, or completely lose the signal and show a red x, stating that no signals could be found. The strange thing is, all the other PCs in my house connect wirelessly fine, and so did the laptop that was in the same room as this PC. After a system restore, the internet started working again. Then it stopped. Another restore later, it works. Now it's intermittent again.

Internet Random Disconnect And Reconnect

May 15, 2011

When doing anything on my PC, gaming, browsing, whatever, I will have random disconnects for a few seconds and it will reconnect. I don't get the "your network cable has been unplugged" message, it just stops working for a second or two and starts working again. This has been happening for a few months after a fresh install of windows xp and I haven't really tried to fix it.Every other computer in the house is fine except this one, it can't be the modem because a new one was installed a few days ago and its the same problem. The router was reset within the last week as well. I think the problem is with this computer alone but I don't know where to look.  The problem didn't happen for a few days after I put a new network card in, but soon after it continued happening. I also have tried a few different CAT5 cables, even the XBOX one but nothing resolved the issue.

Internet Connection Keeps Disconnecting At Random Times?

Oct 26, 2012

I have fiber optic Internet with static ip and keeps disconnecting at very random times. It started 3 weeks ago, before it worked perfect. Most of times dcing 3 times per hour. But sometimes working for hours without dcs. Usually disconnects only for half minutes then reconnect, it can be very annoying. The provider keep saying that need change router. I'm tried three different of routers already, but keeps disconnecting. I'm tried connect the net directly into my cpu, without router, but not worked, dc-ing too. I tried ping the default gateway when its disconnected, and its saying: request timed out.What else can i try? It should be, that the provider has too many clients, and their router collapsing?

Dell XPS 410 - Random Internet Disconnection By Desktop PC

Jan 2, 2011

I have a Dell XPS 410 desktop PC purchased in 2006 now running Windows 7 (32-bit) that is hard-wired to D-Link 825 dual band N router.

The Problem- The desktop, when actively using the internet, will randomly lose connection to the Internet, then by just waiting, it re-acquires a connection. When it does this it sometimes also disconnects other laptops that are wirelessly connected through the same router, or at least slows them way down. Also similarly effects a hard-wired X-Box 360 (either loses connection all together or, the games start to severely lag) much to the disdain of my game playing kids.

Internet Access Keeps Dropping At Random Times

Feb 17, 2011

I have a brand new Dell laptop running windows 7 connected to a sky router wirelessly. My internet connection randomly just drops. At 1st I could just click on the yellow triangle and troubleshoot and it would reset the network adapter. I cannot do that now - Im having to disable the adapter and the enable it and Im back on the internet.I have set it up so I am connecting via a manual IP address as I wondered if when the kids PS3 was connecting it was pinching my Ip address.

Internet Would Just At Random Stop For Like 2-3 Seconds Then Catch Up With Itself?

Jun 19, 2011

my internet would just at random STOP for like 2-3 seconds then catch up with itself. I have 3 computers, 1 printer, a laptop and an xbox all setup on a NetGear N300 Router. the 3 computers and xbox are directly connected to the router. the printer and laptop are wireless.The Road Runner Modem is a CISCO Cable Modem DPC2100R2. Now when this random STOP happens... on programs like Teamspeak peoples voices cut out but then quickly catch up with themselves. On Black Ops PC and Xbox everyone freezes for a few seconds then catch up to themselves and I'll get a connection interrupted. I'd be asking friends around me to see if they got that "Connection Interrupted" and they say no. On Rock Band 3 I get randomly disconnected from the game with everyone asking what happened...When this STOP happens... my computer doesn't give me any error message like "Local Area Connection is unplugged" or anything like that. I've tried checking my CISCO modem's log and it shows no problems.Last week I swapped out the Road Runner Modem at their swap shops to see if that was the problem. Obviously it isn't. The Router I had before the NetGear did the same exact thing except it was a westell...I've tried directly connecting the modem to the computer and trying that to see if there was some kind of miscommunication between the router and the modem... same thing.

Random Internet Blips Ruining Gaming?

Aug 16, 2011

I play some games online casually, primarily League of Legends, and about every second sitting the internet has frequent 'blips' of going down for long enough to make the game have connection issues. I've noticed it is the sending that goes down and if the receiving goes down at all, then it is very quick. (The game still plays and I see everything that is happening but cannot respond. This happens in Rift too the rare time I play it and the even rarer flash games I play). Though I have tried many things to fix this issue, it hasn't truly bothered me that much until recently when I realized I play even less than I normally would out of fear the game session will be ruined by the internet.About half a year ago the internet was in very bad shape. It crashed often and stayed down for a long time. My ISP is Comcast (Or Xfinity...), and it took me many weeks of harassing their customer support (off and on) for them to fix it. Then it ran smoothly for a couple months before it started having these blips.

The details:When it has a blip, before, during, and afterwards (I've sat by the modem to watch it happen), there is no indication of the internet having trouble on the modem indicator lights. Nothing changes, and they flash at about the same rate as normal. The router I have is a Linksys, and nothing seems to change on it either during a blip.I have the games port forwarded. All my firewalls including the windows firewall are off. I have updated my wifi and internet drivers on my computer and am using the firmware recommended to me by my ISP for the router.

SMCD3GN - New NIC Losing Internet At Random Times?

Jan 29, 2013

I've been having some problems with my new custom built computer connected wirelessly to my Router. My router is an SMCD3GN. So it is a Router/Modem in one. I am currently using the Linksys AE3000 Wireless-N USB Adapter. I have had a past Wireless USB Adapter, & an internal Wireless network card. The USB quit working & in order for me to get it to work is I have to reinstall the drivers everytime I turn my computer back on. The internal wireless network card would randomly lose internet every 30mins - an hour. Being a gamer, this is very frustrating. So, right now I am using the Linksys USB, and I was just playing a game & talking to some friends on skype & I would lose internet for 2 seconds then it would automatically reconnect. So I am beginning to think that it might be my Router but I tried my USB on my laptop for like 10 mins (I disabled the internal wireless network adapter) & I went into cmd.exe and pinged google for about 10 mins, & it said "Request Timed Out." several times.

Slow Internet At Random Times (usually During Peak Hours)?

isp is Comcast. They have had 2 techs come out here to look at problem and found nothing. I'm on a wireless connection with router in the next room. Modem was replaced a week ago and still problem persists. Landlady says she has no problem (shes the one in the next room and is connected directly) but I think that because she doesn't notice (I play online games so its very noticeable). I have excellent signal from router. This is my report:

Dell :: Random Internet Lag Spikes - Netgear M14xR1 Router

Oct 26, 2012

Since last night 10/26/12 I have been experiencing random lag spikes on all games (Hawken Beta(installed yesterstay), Mechwarrior beta, MW3, and BF3).

* Framerates do NOT drop when the lag occurs
* Lag last for 1-3 seconds
* Lag occurs on both wireless and wired connections
* Lag occurs when no one but myself is on the network and while others are on it as well
* Only occurs while gaming as far as I can tell
* Unsure if other computers on network are lagging because none of them are gaming computers
* I have performed tests using SpeedTest and the ping/DL/UL speeds are normal
* Tried turning off Anti-virus (Kaspersky). No Change
* Ran virus and malware scans using Kaspersky and malwarebytes. Both negative results
