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. I also notice random slowdowns when browsing the internet or whatever I'm doing that uses the internet.

D-Link DIR-655 Causing Internet Slow Downs?

Jun 10, 2011

I have been using my DIR-655 for about 2 weeks now with Road Runner wideband services. Starting yesterday my internet became very slow and I discovered the cause was the router. I tried resetting it to factory settings and things will be fine and run smoothly for about 5-15 minutes but after that it goes back to being extremely slow. My speed tests would go from 10ms (normal) to 250-450ms. Before this issue occurred the Dlink was perfect, had full speeds. I am running a wire Ethernet connection.

I am currently using revB and tried upgrading firmware to 2.01NA which had no effect, but make my internet seemingly go back to normal for the first few minutes then nosedive again.I have also changed my speed/duplex settings in Network Config to 1gbs Full Duplex. I've also disabled QoS, and still no change. Not sure what else to do.

When directly connected to the modem everything seems fine. The modem is also the provided Motorola SBG6580 which I have called Time Warner to set the modem into bridge mode and have the DIR-655 connected to it.

Intermittent Internet Speed Slow Downs With A TP Link Usb Adapter?

Mar 22, 2012

I have recently bought a TP Link wireless usb adapter (TL-WN727N). Initially I had some issues with drivers but solved that and my internet was working perfectly for around 2 days. However recently the internet speed has dropped down to extremely low speed periodically for no apparent reason. I can be downloading something at around 700kBps one moment then only have 100B/s the next. [CODE]

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

Apr 30, 2011

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:

Lot Of Drop-outs / Random Disconnections And Slow Speed?

Sep 25, 2012

I have setup the existing wifi router (couple of years ago) so do have the basic networking knowledge but am not up-to-speed with all the latest developments in the industry2. ISP have provided a '******' ADSL modem that i need to connect to get this whole netwrok working. its only supports ethernet connections - (i live in a third world country)3. I have installed a TP-link Wifi router (WR841Nd). The modem on stand-alone basis is fairly decent, covers decent range on ground floor (my house is fairly big and is double story building) but with few dead spots. It supports N series so speed is quite good as long as one is within range.

Problemi have been living with it for couple of years but since recently i have been experiencing a lot of drop-outs/random disconnections and slow speed. I have tested my wifi router at friend's place and it showed no signs of problems so it has to be my ADSL modem (phone line is fine, though i am not close to exchange but that is not an issues as my neighbours are using the same phone line/ISP and they dont have an issue)another problem i have is the coverage, my current wifi only covers the ground floor and i would like to extend this to upper portione am looking to change my ISP provided ADSL modem. The problem is i dont know if i buy an ADSL modem off amazon and whether it would work or not because the setup is not straight forward and the ISP staff is corrupt. They dont provide with quality hardware neither do they have technical competence so i literally have to beg them at time to at least come and see the problem.Question1: ISP provided ADSL modem replacementi know the settings for ISP modem so i can search how i can replicate the same with Billion but can this work?Question2: RAnge ExtenderI am thinking of buying couple of powerline wireless extenders from netgear.

Small Network / Random Computers Lose Browsing At Random Times?

Dec 29, 2012

Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

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

No Internet After Random Period?

Dec 27, 2012

I have Windows XP Pro SP3. After a random period of maybe 30 mins to a few hours, my internet connection seems inexistant. PC reacts like there is no internet cable plugged in. I've checked the ipconfig command in command prompt before my internet shuts down and after and there was a change. A few lines(IPs) were missing after my internet fell.

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.

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.

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.

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.

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.

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.

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

WL-530g V2 Wireless Router / Random Drastic Internet Speed Decrease?

Sep 18, 2012

I've been having this problem for quite some time, mostly since my mother bought her first Asus Laptop that came with an Asus WL-530g V2 wireless router.Problem is sometimes I get a random disconnect where Local Area Connection is identifying. On some occasions it reconnects on it's own after a few seconds, other times I have to diagnose the problem and I get a "Windows doesn't have a valid IP config" problem but it fixes that.The other problem, and I don't know if the two are related is that very often, for short/long periods of time I get a drastic reduction of internet speed. From what I can tell, it's got to be something to do with the network configuration or the actual router itself, it's very old and Asus stopped making firmware for it in '09. Useful data Basically I have a wired connection from my desktop to the wireless router.

>>>Atheros ar8151 pci-e gigabit ethernet controller (driver up to date)

Linksys Wireless Router :: E4200 Disconnects Internet At Random Times

Internet Slow On One PC Not The Others?

Jun 23, 2011

we recently decided to put wireless in the house, and the problems really started from there. The internet was really slow, especially considering the bandwidth was upgraded as well (since my dad thought the internet seemed slower on wireless, though I thought it was expected). I have this really old laptop with Vista/Fedora dual boot and the internet works fine there; my dad's laptop also works fine, but the home's desktop (which has the wireless adapter) is incredibly slow. I've tried uninstalling the LinkSys wireless manager and letting windows handle it, but no luck there. I thought maybe it was cluttered with stuff or maybe it was infected but Avira and SuperAntiSpyware only find a couple of cookies which they delete at the end of their scan.

I should mention that with the upgrade in bandwidth we got a new router (or modem? whatever); I can't quite remember if the internet was slow before or after, but it was put up after the wireless.

When it can see the router and connect to the internet, speeds are so slow that most web pages cannot load (Google comes up, searches are slow, can't open any sites). The new laptop is attempting its connection through wireless. My Device Properties says I have an Atheros AR8152/8158 PCI-E Fast Ethernet Controller (NDIS 6.20). Wireless Network Connection Properties says I'm connecting using Intel Centrino Wireless-N 2230. I'm sending and receiving millions of packets, getting great signal quality, and have 144.0 Mbps. IPv4 is connected but IPv6 is getting no internet. The router is a Linksys, though I don't know the model number.I am typing this on another laptop that is connecting via wireless, also a Toshiba. I have another laptop and desktop which can connect via wireless and three desktops which connect via ethernet cable.

It was a miracle I even got to download anything. After I got Google Chrome I decided to go on YouTube to test if it was slow as well. The videos need time to buffer even if on 240p. On my PC the internet loads fast, no need to buffer videos at all and the other webpages load fast too. I have a Ps3 here too, but it's YouTube app's videos load fast too, no need to buffer. I can play online with 4 bars and no problems at all. Why is the internet so slow on my laptop?
